2004 Chevrolet Impala Engine Problems

Your car stalled while you were exiting a highway at 65 mph and wouldn't restart. You then noticed smoke coming from under the hood, and when you opened it, you saw a fire underneath the engine. The fire department had to extinguish it. You had also noticed a battery warning light was on before the stalling occurred. The vehicle was towed but not inspected to determine what caused the fire.

While driving at 60 mph, your engine suddenly shut off and heat came pouring through the air vents. When you opened the hood to investigate, flames erupted from the engine manifold—you had to use a floor mat to extinguish them. After restarting, the check engine light came on. The issue appears to involve oil leaking from the valve cover and front gasket area, which likely caused the engine fire.

Your car suddenly lost power while you were driving at 40 mph, forcing you to pull over. After waiting 5-10 minutes, you were able to restart it. Your check engine light came on, and you suspect this may be related to a known engine issue (NHTSA Campaign 15V701000). The problem may require diagnostic testing at a dealer to identify the underlying cause.

While driving at 35 mph, your low oil pressure warning light came on and you noticed an oil leak underneath the car. You discovered that an oil line had become detached near the front passenger wheel well. After reattaching the line, a mechanic informed you that the engine needed to be replaced due to the damage from the oil loss. The repair will likely involve replacing the engine or having the oil line professionally reconnected and inspected to prevent future leaks.

TL* THE CONTACT OWNS A 2004 CHEVROLET IMPALA. THE CONTACT HAD NOT EXPERIENCED A FAILURE PRIOR TO BEING REPAIRED AT THE DEALER (PETE MOORE AUTOMOTIVE, 103 AND 106 NEW WARRINGTON RD PENSACOLA, FL 32506 850-456-7000, EXT 466) PER NHTSA CAMPAIGN NUMBERS: 15V701000 (ENGINE AND ENGINE COOLING) AND 15V201000 (ENGINE AND ENGINE COOLING). THE CONTACT WAS UNCERTAIN IF THE REPAIR CAUSED A FAILURE WHEN THE PARTS WERE REPLACED. THE CONTACT FELT THAT THE OEM PARTS MAY HAVE FAILED AND THAT THE MANUFACTURER NEEDED TO PROVIDE A SOLUTION TO THE DEALER TO REPAIR THE VEHICLE. THE CONTACT WAS UNABLE TO PREVENT AN INTERNAL OIL LEAK. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO STATED THAT THE REAR GASKETS WERE LEAKING. THE MANUFACTURER WAS NOTIFIED OF THE FAILURES. THE FAILURE MILEAGE WAS NOT AVAILABLE.

WHEN TRYING TO START MY VEHICLE, THE SECURITY LIGHT COMES ON AND THE VEHICLE WILL NOT START FOR 10 MINUTES. THIS OCCURS ON A WEEKLY BASIS AND OCCURS IN MANY LOCATIONS. SOME OF THE LOCATIONS INCLUDE VERY RURAL AREAS WITH NO PHONE SIGNAL, DURING HIGH TEMPERATURE DAYS WHEN A CHILD IS PRESENT IN THE VEHICLE. TEN MINUTES IS A LONG TIME TO SIT WITH NO COOLING AVAILABLE AND NO ABILITY TO CONTACT ANYONE. THIS OCCURS WITH NO WARNING AND NO CERTAIN WEATHER. GMC IS AWARE OF THE PASSCODE/PASSKEY FAILURES BUT HAS REFUSED TO RECALL SUCH MALFUNCTIONS, EVEN THOUGH IT AFFECTS THOUSANDS OF VEHICLES.

THERE IS A RECALL ON THIS CAR. WE BROUGHT IT TO THE DEALER WITH AN APPOINTMENT AND THE DEALER DID NOT PERFORM THE RECALL SERVICE.

INTAKE MANIFOLD GASKET. WHY ARE THE DEFECTED? THERE ARE SO MANY COMPLAINTS ABOUT FAULTY ONES AND STILL YOU HAVE NOT CHANGED TO BETTER GASKETS. FIRST THE HEAT GOES AND THEN THE CAR OVERHEATS FOR NO APPARENT REASON. CHANGED THE WATER PUMP AND THERMOSTAT. NOW THE GASKET. FOR THE PRICE YOU PAY FOR THIS CAR IT SHOULD NOT HAVE TO COST ME ANOTHER 800 TO 1200 MORE FOR A PART YOU CAN FIX WITH CHANGING YOUR PRODUCT YOU USE. I HAVE OWN GMC PRODUCTS FOR OVER 20 YEARS AND THIS IS MY FIRST COMPLAINT ABOUT THEM. JUST BECAUSE I AM HAVING PROBLEMS WITH MY IMPALA WILL NOT KEEP ME FROM TELLING PEOPLE THAT GMC HAS GOOD CARS. JUST WISH THIS PROBLEM WILL FIXED FOR FUTURE OWNERS. WOULD HATE TO BE CALLED A LIAR. ONE OF OUR GMC'S IS A 78 SIERRA CLASSIC WHICH WAS BOUGHT BRAND NEW IN 77. *TR

AFTER PARKING MY CAR, I JUST HAPPENED TO NOTICED SMOKE COMING OUT FROM THE FRONT OF CAR AND I WAS FORTUNATE ENOUGH TO HAVE A DRY CHEMICAL FIRE EXTINGUISHER AVAILABLE TO PUT OUT THE FLAMES. IT APPEARS THAT THERE WAS A VALVE COVER OIL LEAK THAT HAD DRIPPED ONTO THE EXHAUST MANIFOLD THAT CAUSED THE OIL TO IGNITE INTO FLAMES. RESULTING DAMAGE THAT I'M VISUALLY ABLE TO SEE WAS TO ALL SPARK PLUG WIRES, ENGINE COILS, PLASTIC ENGINE COVER, OIL DIPSTICK, RIGHT ENGINE STRUT, WIRING HARNESS PIGTAIL GOING TO COIL PACK ASSEMBLY AND UNDER HOOD INSULATION. I WILL NOT KNOW FULL EXTENT OF DAMAGE UNTIL I ATTEMPT TO PERFORM THE REPAIRS MYSELF. I HAVE PHOTOS IF SOMEONE WOULD LIKE TO VIEW THEM. ALSO, THE MILEAGE I LISTED OF 99,400 IS APPROXIMATE, IT IS NOT EXACT AS I AM NOT NEAR MY CAR AT THE MOMENT. *TR

TL* THE CONTACT OWNS A 2004 CHEVROLET IMPALA. THE CONTACT STATED THAT WHILE DRIVING 25 MPH, THE VEHICLE STALLED AFTER THE CHECK ENGINE LIGHT ILLUMINATED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 196,000.

TL* THE CONTACT OWNS A 2004 CHEVROLET IMPALA. WHILE DRIVING 40 MPH, THE CONTACT HEARD AN ABNORMAL SOUND COMING FROM THE ENGINE AND THE RADIATOR OVERHEATED. THE VEHICLE FAILED TO SHIFT OUT OF PARK. THE CONTACT WAS ABLE TO MERGE THE VEHICLE TO THE SIDE OF THE ROAD AND POURED WATER INTO THE RADIATOR. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC FOR DIAGNOSTIC TESTING, BUT THE CAUSE OF THE FAILURE COULD NOT BE DETERMINED. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS UNKNOWN.

TL* THE CONTACT OWNS A 2004 CHEVROLET IMPALA. WHILE IDLING AT A TRAFFIC LIGHT, THE VEHICLE WAS UNABLE TO ACCELERATE AND THE REDUCE ENGINE POWER WARNING INDICATOR ILLUMINATED. AN INDEPENDENT MECHANIC STATED THAT THE THROTTLE BODY NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED AND THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS 114,000.

TL* THE CONTACT OWNS A 2004 CHEVROLET IMPALA. THE CONTACT STATED THAT WHILE DRIVING AT APPROXIMATELY 65 MPH AND GOING OVER A POT HOLE. THE VEHICLE STALLED WITHOUT WARNING. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING WHERE THE FAILURE WAS UNABLE TO BE DIAGNOSED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 64,000.

MY VEHICLE RECENTLY STARTED HAVING ISSUES WITH OVERHEATING. AS SOON AS IT WOULD WARM UP THE GAUGE WOULD GO THE WHOLE WAY PAST THE HOTTEST POSSIBLE TEMP ON THE DASH. MY HOT COOLANT TEMP LIGHT WOULD COME ON AND THEN I WOULD HAVE TO PULL OVER AND TURN THE CAR OFF TO LET IT COOL. I TOOK IT TO A MECHANIC WHO SAID THAT I WOULD HAVE TO REPLACE THE HEAD GASKETS AND INTAKE GASKETS. HE RESEARCHED IT AND SAID THAT HE FOUND THAT IMPALAS FROM 20003-2007 HAD PROBLEMS WITH THE ENGINES BECAUSE OF AN ADDITIVE THAT WAS PUT IN THE ENGINE. I PAID HIM OVER 1000 DOLLARS TO FIX THE ISSUE BECAUSE BEFORE I TOOK IT TO HIM I TOOK IT TO A DIFFERENT MECHANIC WHO SAID IT WAS THE RADIATOR SO I GOT THAT FIXED WHICH COST ME CLOSE TO 500 DOLLARS. SO EVEN AFTER I GOT BOTH OF THESE PROBLEMS FIXED MY CAR STILL OVERHEATS. *TR

ENGINE STOPS RUNNING ARE RANDOM TIMES. WON'T RESTART FOR ABOUT 20 MINUTES. VERY UNSAFE CONDITION. DEALER SAYS THEY CANNOT REPLICATE THE OCCURRENCE, BUT WOULDN'T COME CHECK OUT THE VEHICLE WHEN IT STALLED 1 MILE FROM THEIR DEALERSHIP. *TR

I BOUGHT CAR 2 YRS AGO AND DROVE IT FOR 3 MONTHS NO PROBLEMS THEN SAT FOR 6 MONTHS, I START DRIVING IT AND THIS IS ALL THE STUFF THAT WENT OUT AND STUFF STILL GOING ON. RADIATOR TEMP SENSOR, WATER PUMP, HEATER, WATER PUMP BEARING, INSTRUMENT CLUSTER, LOW COOLANT SENSOR, RADIATOR, VSS, KEY STUCK IN IGNITION, LOCK CYLINDER, 8 WIRES UNDER HOOD SHREDDED IN HALF DUE TO RUBBING ON BELT, POWER LOCK WONT WORK ON DRIVER SIDE DOOR, CHIMES GO OFF WHEN KEY NOT IN IGNITION. MY PROBLEM NOW IS KEY LOCKED UP AGAIN FINALLY GOT IT TO TURN THEN ANTI THEFT SYSTEM COMES ON AND THE CAR WONT REPROGRAM CODES. MY CODE READER SAYS IT CANT READ FROM CAR. *TR

(1) HEATING SYSTEM FAILED. NO HEAT, COOLANT WAS OK. FAN WAS RUNNING. DEALER EXAMINED. THREE ACTUATORS IN THE ELECTRONICS ARE FAILED AND HAVE TO REPLACE AT A COST OF OVER $550.00 (2) TEMPERATURE GAUGE STOPPED MOVING. DEALER EXAMINED. ESTIMATED COST OF $~400.00 TO REPLACE IPC UNIT. THERE IS ONE OF THE RECALLED IPC UNITS FOR GM AUTOS MADE BETWEEN 2003-2007; BUT IMPALA WAS NOT INCLUDED IN THE RECALL LIST. I DON'T KNOW WHY? SAME ELECTRONICS FAILED IN ONE UNIT MUST BE RECALLED FROM ALL THE UNITS.. THESE DEFECTS COULD INCREASE HEAT IN THE ENGINE BLOCK AND COULD INCREASE FUEL CONSUMPTION, FAILURE OF THE ENGINE AND POSSIBLY CAUSE FIRE, CONTACTED GM BUT THEY WERE NOT COOPERATIVE AND DENIED ANY CLAIMS. *TR

WAS DRIVING DOWN THE HIGHWAY AND CAR STARTED TO SLOW DOWN. NO TEMPERATURE LIGHT CAME ON BUT CAR STARTED TO SMOKE A LITTLE UNDERNEATH HOOD. STOPPED CAR AT AN EMPTY LOT, AND HAD IT TOWED TO A GARAGE. THEY SAID MY ENGINE HAD OVERHEATED AND NEEDED A NEW HEAD GASKET. IT HAD PREVIOUSLY HAD A HEAD GASKET PUT ON IT ABOUT A YEAR AGO, SO THIS WOULD HAVE BEEN THE SECOND ONE. MECHANIC ADVISED ME NOT TO HAVE A SECOND HEAD GASKET JOB BUT INSTEAD ADVISED ME TO GET ANOTHER ENGINE FOR THE CAR. *TR

TL* THE CONTACT OWNS A 2004 CHEVROLET IMPALA. THE CONTACT STATED THAT WHILE DRIVING 65 MPH, THE TEMPERATURE GAUGE RAPIDLY INCREASED AND A COOLANT ODOR WAS EMITTED INSIDE OF THE VEHICLE. THE VEHICLE HAD NOT BEEN DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE DEFECT. THE APPROXIMATE FAILURE MILEAGE WAS 141,000. THE VIN WAS UNAVAILABLE.

CHEVY IMPALA 2004 LS- THE VEHICLE IS STOPPING COMPLETELY WHILE DRIVING OR SITTING AT INTERSECTION. THERE IS NO WARNING, NO MESSAGE, IT JUST DIES. THE STEERING GOES WHEN THIS HAPPENS SO I CANNOT EVEN GET OFF THE ROAD. THEN THERE ARE TIMES THAT THE CAR WILL NOT START AT ALL AND I HAVE BEEN STRANDED. EVENTUALLY AFTER ABOUT 20 MINUTES THE CAR WILL START- I HAVE ALREADY REPLACED THE STARTER BUT THE PROBLEM STILL EXISTS. I HAVE HAD THE CAR CHECKED OUT AT 2 DIFFERENT SHOPS (FIRESTONE) AND THEY CANNOT FIND THE PROBLEM. THERE ARE NO CODES COMING UP. THEY ARE COMPLETELY PERPLEXED. CHEVY STATES THEIR MECHANICS ARE BETTER. ALSO THE CLUSTER PANEL IS GONE AND CHEVY IS AWARE OF THE PROBLEM BUT THEY ONLY RECALLED CERTAIN MODELS AND DID NOT INCLUDE THE IMPALAS. I HAVE 2 ESTIMATES REGARDING FIXING THIS PROBLEM BUT THE QUOTES ARE $500.00. I DO NOT FEEL THAT I SHOULD HAVE TO PAY FOR THIS WHEN CHEVY KNEW THEY HAD THIS PROBLEM WITH CLUSTER PANELS AND OMITTED THE IMPALAS IN THEIR RECALL. SO, TO RECAP: THE CAR DIES IN TRAFFIC (ALMOST HIT TWICE), I DO NOT KNOW HOW MUCH GAS I HAVE, HOW FAST I AM GOING, OR IF THE CAR IS OVERHEATING. IN DEALING WITH CHEVY I WAS TOLD TO TAKE THE CAR TO A CHEVY DEALERSHIP. THEY GAVE ME A PLACE THAT IS 2 1/2 HOURS HOUSE AWAY FROM MY HOME. I WAS ALSO TOLD THAT I WOULD HAVE THE HONOR OF PAYING FOR THE DIAGNOSTICS. IN RESEARCHING THIS PROBLEM, I HAVE PULLED UP SEVERAL COMPLAINTS FROM OTHER CHEVY IMPALA 2004 OWNERS THAT ARE EXPERIENCING THE SAME MULTIPLE PROBLEMS. I ALSO NOTICED THAT MOST OF THE COMPLAINTS ARE STATING THAT THE SAME ISSUES OCCURRED AT APPROX. THE SAME MILEAGE AS MINE. I HAVE DISCUSSED THIS WITH CHEVY CUSTOMER SERVICE AND BASICALLY THAT WAS IGNORED. THIS CAR IS HAZARDOUS TO DRIVE AND POTENTIALLY WILL CAUSE BODILY HARM. DEALING WITH CHEVY IS POINTLESS. ALL THEY CAN THINK OF IS HOW MUCH MONEY THEIR DEFECTS WILL BRING IN. *TR

WHILE DRIVING IN HEAVY TRAFFIC, IT JUST STOPS RUNNING. MY HUSBAND PUTS THE CAR IN NEUTRAL AND IS ABLE TO START IT BACK UP AGAIN. IT HAS DONE IT A FEW TIMES SINCE THAT OCCURRENCE. THIS COULD RESULT IN A VERY SERIOUS SITUATION IF THE CAR STALLS IN AN INTERSECTION AND WON'T RESTART. THE CAR ALSO HAS A SECURITY ISSUE THAT PREVENTS US, AS THE OWNER FROM STARTING IT. THIS HAS BEEN AN ONGOING PROBLEM FROM THE PURCHASE DATE. IF YOU TURN ON THE IGNITION AND LET IT SIT FOR 10 TO 15 MINUTES, IT WILL START UP. WE NOW LEAVE THE CAR RUNNING WHEN FILLING THE CAR WITH GAS BECAUSE WE HAVE HAD TO SIT AND WAIT FOR IT TO RESTART AT THE PUMP. THIS COULD CAUSE A VERY SERIOUS PROBLEM ALSO. IF YOU GO ON LINE, YOU WILL SEE NUMEROUS COMPLAINTS ABOUT BOTH OF THESE PROBLEMS. WE BOUGHT THIS CAR USED AND KNEW WE WOULD BE RESPONSIBLE FOR SOME ISSUES, BUT NOT THIS, IT SHOULD BE A RECALL ISSUE. WE HAVE HAD TO REPLACE THE RACK AND PINION (VERY COSTLY) ALL NEW BRAKES AND ROTORS, ALL NEW TIRES, AND SOME OTHER MINOR ISSUES. I FEEL, AS DO NUMEROUS OTHER GM OWNERS, THIS IS A FACTORY DEFECT IN THE SECURITY SYSTEM (PASSLOCK KEY SYSTEM), CAUSING BOTH PROBLEMS. ANYONE HAVING THIS PROBLEM, SHOULD BE ABLE TO TAKE THE CAR TO THE DEALERSHIP AND THEY SHOULD HAVE TO FIX IT AT NO COST TO THE OWNER OF THE VEHICLE. I TOOK IT TO THE DEALERSHIP JUST AFTER WE PURCHASED IT AND HE SAID HE WOULD HAVE TO REPLACE THE IGNITION AND SOMETHING ELSE AT A COST OF ALMOST $800. I AM CERTAIN THIS CAN BE TAKEN CARE OF BY REROUTING WIRING IN THE SECURITY SYSTEM AT A VERY MINOR COST, OR JUST RESETTING THE COMPUTER SYSTEM. ANY ASSISTANCE YOU CAN GIVE WOULD BE GREATLY APPRECIATED.

TL* THE CONTACT OWNS A 2004 CHEVROLET IMPALA. THE CONTACT STATED THE VEHICLE FAILED TO START. ON A SEPARATE OCCASION THE VEHICLE RESTARTED AND WAS TAKEN TO AN INDEPENDENT MECHANIC. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 98,000 AND THE CURRENT MILEAGE WAS 103,000.

VEHICLE STALLED OUT / STOPPED WHILE TRAVELING DOWN THE ROAD. IT HAS DONE IT TWICE NOW. THIS CAR IS FULLY EQUIPPED WITH CRUISE CONTROL AND TRACTION CONTROL. AFTER THE FIRST TIME (THREE DAYS AGO) WE TOOK IT TO A DEALER AND THEY COULD NOT FIND ANY CODE (S) AND OR REPLICATE IT. IT JUST HAPPENED AGAIN TODAY. BOTH TIMES THE CAR STARTED RIGHT UP. THIS COULD BE A DISASTER AT HIGH SPEEDS ON AN INTERSTATE. THANK YOU. *TR THE CONSUMER STATED THE VEHICLE STALLED FOR A THIRD TIME. THE DEALER RAN IT FOR CODES AND IMMEDIATELY, IT CAME BACK AS A PROBLEM WITH THE MASS AIR SENSOR. IT WAS REPLACED AND SO FAR, THERE HAVE BEEN NO MORE PROBLEMS. UPDATED IVOQ 08/01/12

THE TRACTION CONTROL TURNS ON FREQUENTLY. THIS CAUSES THE CAR TO MAKE A GRINDING NOISE. WHEN BRAKING THE CAR MAKES A GRINDING NOISE AND CAR IS NOT STOPPING IT FEELS LIKE IT'S LOCKING UP AND SLIDING. IN A SUDDEN STOP NEEDING TO BE MADE IS AT GREAT RISK OF A ACCIDENT. I HAVE REPLACED A ELBOW SHAPED PART THAT HAS BUSTED OPEN TWICE. CAR IS CONSTANTLY OVER HEATING THE RADIATOR CAP HAS A RUSTIC CLAY LIKE SUBSTANCE. IT WON'T HOLD ANTIFREEZE, I DON'T SEE A LEAK BUT IT NEEDS REFILLED QUITE OFTEN. THE ENGINE SMOKES, THE CARS RPM'S WILL FLEX UP AND DOWN AND THE CAR WILL JUST CUT OFF. I'M WONDERING IF THE RUSTIC CLAY LIKE SUBSTANCE HAS GONE THROUGH MY ENGINE AND IS CAUSING ME MANY PROBLEMS WITH IT. I HAVE FOUND REPORTS OF LAWSUITS IN PAST REGARDING DEXICOOL IN GM CARS DOING THIS AND RUINING THE ENGINE. THE PROBLEMS IN THE REPORTS ARE JUST LIKE MINE AND MANY OTHERS ON HERE. HELP!!' *TR

ROCKER ARM BOLTS CAME OUT OF HEAD DISABLING CYLINDER #1. CAUSING ENGINE TO RUN ROUGH AND COULD NOT EXCEED 15MPH. THREADS IN HEAD FAILED. THIS HAPPENED AGAIN IN DECEMBER 28, 2010 AFFECTING CYLINDERS #3 AND #5. NOW AGAIN THIS ISSUE AS OF MARCH 9, 2012 IN CYLINDER #2. IN EACH OCCURRENCE THREADS FROM HEAD WERE FOUND IN BOLT THREADS. BOLTS WERE LOOSE DISABLING CYLINDER FROM WORKING. THIS HAPPENS WITHOUT WARNING AND DUE TO CONCERN OF FURTHER DAMAGING ENGINE, CAR REQUIRES TOWING. THIS SEEMS TO BE A DEFECT IN THE MATERIALS THE HEAD WAS MADE OF. *TR

SECURITY LIGHT COMES ON WHILE DRIVING AFTER CAR IS TURNED OFF IT WONT START UNLESS I TURN ON THE IGNITION SWITCH AND LET IT SIT FOR 20 MINUTES THEN THE CAR WILL START. TURN SIGNALS LIGHTS RARELY WORKS PROPERLY AND THE CHECK ENGINE LIGHT STAYS ON I'VE MADE THE REPAIRS UNDER THE CODES AND THE CHECK ENGINE LIGHT IS STILL ON THIS IS DEALING WITH THE EMISSION TESTING. *TR

PASS LOCK SYSTEM "SECURITY" LIGHT COMES ON AND THE CAR WILL NOT START. HAPPENS RANDOMLY. *KB

TL* THE CONTACT OWNS A 2004 CHEVROLET IMPALA. THE CONTACT WAS DRIVING 55 MPH WHEN THE VEHICLE STALLED WITHOUT WARNING AND WAS CRASHED INTO BY ANOTHER VEHICLE. THE CONTACT SUSTAINED WHIPLASH INJURIES AND WAS TRANSPORTED TO THE HOSPITAL. A POLICE REPORT WAS FILED. THE VEHICLE WAS DESTROYED. THE CONTACT STATED THAT THE VEHICLE WAS PREVIOUSLY REPAIRED BECAUSE THE VEHICLE WOULD FAIL TO START AND THERE WERE OTHER ELECTRICAL FAILURES. THE MANUFACTURER WAS NOT CONTACTED IN REGARDS TO THE FAILURE. THE FAILURE MILEAGE WAS 125,000.

2004 IMPALA W/ 3.8L ENGINE STALLS WHEN DECELERATING, LEAVING THE CAR VERY DIFFICULT AND UN-SAFE TO DRIVE. CURRENTLY, THE ENGINE STARTS RIGHT BACK UP, BUT IT TAKES MY EYES OFF THE ROAD TO PUT THE CAR IN NEUTRAL AND RE-START. I HAVE TRIED A FEW INEXPENSIVE THINGS SUCH AS PREMIUM GAS, FUEL INJECTOR CLEANER, AND A NEW FUEL FILTER...NO AFFECT ON THE PROBLEM. THERE IS NO "ENGINE LIGHT" WHICH APPEARS. I HAVE OWNED THIS CAR SINCE NEW AND TAKEN VERY GOOD CARE OF IT. I DO NOT WANT TO TAKE IT TO A DEALERSHIP IF AT ALL POSSIBLE BECAUSE I DO NOT TRUST THEM. UNFORTUNATELY, I MAY BE FORCED TO SINCE THIS IS MY ONLY CAR AND I CANNOT AFFORD A CAR PAYMENT. *TR

NOW AT 117,000 KMS. OR PAST MY FIVE YEAR WARRANTY. SINCE 88,000KMS. HAVE COMPLAINED SEVERAL TIMES ABOUT TEMP GAUGE VERY OUT OF WHACK ON HIGHWAY TRIPS, LEAD ME TO BELIEVE SEVERELY OVERHEATED, BUT NO MESSAGE FROM CAR, JUST GAUGE GOING ALMOST 90 DEGREES PAST "DANGER POINT " OF GAUGE. IN LAST TWO YEARS TEMP GAUGE REPLACED THREE TIMES. OBVIOUSLY NOT THE PROBLEM. RETURNS TO NORMAL FUNCTION IN CITY OR SHORT HAUL DRIVING. STOP FREQUENTLY, AND UNDER HOOD CHECK SHOWS NO SIGNS OF OVERHEATING. CONCLUSION- ELECTRICAL, SENSOR, PROBLEM AND DEALER KEEPS COMING UP WITH COSTLY NEW EQUIPMENT FIXES WHICH DO NOT WORK. NOW THEY WANT TO BLAME A WATER PUMP LEAK AND GASKETS, ALTHOUGH RESERVOIR CAREFULLY WATCHED BY ME. NO LEAKS THERE. HAVE NEVER HAD TO ADD FLUID, ALTHOUGH I KEEP IT ALWAYS IN CAR-THAT IS THE DEXCOOL-WATER MIX. NEVER DOWN LOWER THAN RECOMMENDED, AND THE DEALER WANTS TO GIVE ME A NEW WATER PUMP AND TAKE 1000-1200 OUT OF MY POCKET. THEY HAVE NEVER MENTIONED THE TEMP SENSOR, OR ANY OTHER FIX. TRAVEL ON MOUNTAIN HIGHWAYS 3 TIMES PER YEAR, GAUGE NOW GONE WAY OVER THE TOP 6-8 TIMES. ALWAYS STOP. NO SIGN EVER OF HOSE, RADIATOR, WATER, LOWERED RESERVOIR, OR COMPUTER MESSAGES AS PER MANUAL. HAVE READ OF NUMEROUS SIMILAR PROBLEMS OF THIS MAKE AND MODEL, THE 04 CHEVY IMPALA LS, ALWAYS GAUGES. IN MY CASE I WILL NOT APPROVE ANOTHER TEMP GAUGE "FIX" AND NOW SPEEDOMETER IS ACTING UP AS WELL, JUST LIKE OTHER DRIVERS REPORTED. *TR

MY CAR WOULD RANDOMLY TURN OFF WHILE DRIVING ON THE STREETS AND ON THE MIDDLE OF THE HIGHWAY GOING 55 MILES PER HOUR, OR WHILE STOPPED AT A LIGHT . THE CAR WOULD STALL UP TO 3-4 TIMES PER DAY MOST OF THE TIME AND AS TIME WENT ON IT GOT WORSE. I REPLACED THE FUEL PUMP, FUEL PRESSURE REGULATOR, THE BATTERY, THE FUEL FILTER, THE IGNITION SWITCH, AND THE CAR STILL TURNS OFF IN THE MIDDLE OF NOWHERE. THE LAST TIME IT HAPPENED WAS WHEN MY WIFE WAS DRIVING TO WORK THE CAR STALLED A FEW YARDS AWAY FROM A RAILROAD CROSSING (SINCE SHE QUIT DRIVING ON EXPRESSWAY), LUCKILY IT DIDN'T HAPPEN ON TRACKS, NO TRAIN WAS COMING AT THAT TIME. SHE HAD TO WAIT APPROX. 25 MINS FOR IT TO START AFTER TRYING A FEW TIMES. THE NEXT DAY THE SAME THING HAPPENS BUT THIS TIME IT DIDN'T TURN ON, SO SHE CALLED THE DEALERSHIP AND THEY SENT A TOW TRUCK. THE TOW TRUCK DRIVER, WHEN HE ARRIVED APPROX. AN HOUR LATER, TRIED TO START IT BUT IT DIDN'T START EITHER. SO, WHEN ARRIVED AT THE DEALERSHIP THEY TRIED STARTING IT AND BY THEN IT STARTED. THE SHOP MANAGER, WHOM I HAD RELATED THIS INCIDENT TO WAS AWARE OF THE SITUATION, SO HE THEN ASSIGNED A MECH TO STAND BY THE ANALYZER MONITOR WHILE THE ENGINE WAS RUNNING. THEY KEPT THE ENGINE RUNNING UNTIL IT FINALLY DIED ON THEM AGAIN, WHILE THE MECH WAS STILL THERE, I DON'T KNOW HOW LONG (DIDN'T ASK). AT THIS PARTICULAR TIME THE ANALYZER INDICATED THAT THE CRANKSHAFT POSITION SENSOR WAS THE CAUSE OF THE STALL. NEEDLESS TO SAY IT WAS REPLACED AND IS NOW A MONTH LATER AND IT'S RUNNING JUST FINE. NOT A HINT OF STALLING NOR ANYTHING ELSE. MY CONCERN IS THAT ANYTHING CAN HAPPEN ON A HIGHWAY FROM A CAR THAT TURNS OFF RANDOMLY DUE TO THE CRANKSHAFT POSITION SENSOR. *TR

TL*THE CONTACT OWNS A 2004 CHEVROLET IMPALA. THE CONTACT ATTEMPTED TO START THE VEHICLE WHEN THE SECURITY WARNING INDICATOR LIGHT ILLUMINATED ON THE INSTRUMENT PANEL. THE ENGINE WOULD NOT OPERATE WHILE THE SECURITY WARNING INDICATOR WAS ILLUMINATED; HOWEVER, THE ENGINE STARTED AFTER APPROXIMATELY TEN MINUTES. THE CONTACT STATED THAT THE FAILURE APPEARED TO BE MORE PRONOUNCED WHEN THE TEMPERATURE WAS 50 DEGREES. THE IDENTICAL FAILURE OCCURRED TWENTY TIMES. THE VEHICLE WAS TAKEN A DEALER WHERE THE TECHNICIAN STATED THAT THE FAILURE WAS CONTRIBUTED TO THE VCM UNIT AND CONNECTORS, WHICH HAD BEEN REPLACED. THE FAILURE CONTINUED TO OCCUR. THE FAILURE MILEAGE WAS 97,000. THE CURRENT MILEAGE WAS 105,000.

WAS IN MY CAR DRIVING SMOKE CAME FROM UNDER THE HOOD. RAISED THE HOOD AND IT WAS ON FIRE. *TR

FAILURE OF LOWER INTAKE GASKETS ON 2004 CHEVROLET IMPALA. *TR

ENGINE TEMPERATURE GAUGE STOPPED WORKING, THEN SHORTLY AFTERWARDS THE SPEEDOMETER FAILED. DOES NOT READ THE CORRECT SPEED OR READS 0 MOST OF THE TIME. *TR

FAILURE: LOWER INTAKE GASKET FAILED DUE TO DEXCOOL ANTIFREEZE. DEXCOOL INSTALLED AT FACTORY. VEHICLE HAD SUDDEN SERIOUS COOLANT LEAK . VEHICLE OVERHEATED ON HIGHWAY AND STRANDED OWNER. VEHICLE WAS TAKEN TO DEALER FOR SERVICE. DEALER TOLD OWNER TO REPLACE GASKET AND COOLANT. SERVICE TECHNICIAN REPLACED DEXCOOL WITH ANOTHER LONG LIFE BRAND OF ANTIFREEZE. THE ORIGINAL DEXCOOL ALSO CLOGGED THE RADIATOR WHICH REQUIRED EXTRA FLUSHING WITH ADDITIONAL CHEMICALS. *TR

TL*THE CONTACT OWNS A 2004 CHEVROLET IMPALA. WHILE DRIVING IN REVERSE OR ACCELERATING AT VARIOUS SPEEDS, THE CONTACT HEARD A LOUD NOISE. HE TOOK THE VEHICLE TO THE DEALER AND THEY FOUND THAT THE MOTOR MOUNT BOLT LOCKS WERE OPENED, WHICH MAY HAVE CAUSED THE ENGINE TO FAIL. THE DEALER TIGHTENED THE BOLTS. THE CONTACT WAS AWARE OF THE SAFETY RISK INVOLVED. THE CURRENT AND FAILURE MILEAGES WERE 77,000.

SECURITY LIGHT WENT ON LAST MONTH. IT WAS TAKEN IN IMMEDIATELY FOR REPAIR. I WAS TOLD IT WAS THE IGNITIION CYLINDER. THE CAR ALSO MAKES A VIBRATING NOISE ON ACCELERATOR. I WAS TOLD THIS WAS THE DRIVE SHAFT AND THE CATALITIC CONVERTER. ALL REPLACED. THE CAR STILL MADE NOISE WHEN LEFT SERVICE AT NORTHEAST AUTO CENTER IN PHILADELPHIA PA WHERE IT WAS PURCHASED. YESTERDAY THE LIGHT FOR SECURITY IS BACK ON. 2004 CHEVY IMPALA VERY DISAPPOINTED. CAR HAS 55,000 MILES. AT 36K THE RADIATOR AND WATER PUMP WENT DURING FUNERAL PROCESSION. *TR

2004 CHEVY IMPALA WITH STEERING FAILURE. CUSTOMER STATES THAT THE VEHICLE WOULD NOT STOP, SO SHE HAD TO HIT A CURB, WHEN THE CAR WAS RESTARTED SHE DROVE ABOUT ANOTHER MILE AND THE FAILURE OCCURRED AGAIN. *KB THE PROBLEM WAS DETERMINED TO BE A SPEED SENSOR FOR THE ELECTRIC POWER ASSIST IN THE STEERING COLUMN. THE CONSUMER ALSO STATED THE ENGINE WOULD MISFIRE. THE DEALER REPLACED THE CAMSHAFT POSITION SENSOR. *JB

MY 2004 IMPALA SS HAS HAD SEVERAL FAILURES OF THE INSTRUMENT PANEL CLUSTER. THE FIRST WAS INCORRECT SPEEDOMETER READINGS THAT LEAD TO TOTAL FAILURE OF THE SPEEDOMETER (STICKING AND/OR ERRATIC BEHAVIOR OF THE SPEEDOMETER NEEDLE). THE SECOND WAS IMPROPER FUEL LEVEL INDICATION (HIGH LEVEL SHOWN WITH LOW FUEL LIGHT COMING ON - ALMOST NO FUEL LEFT). THE LATEST IS INCORRECT OIL PRESSURE INDICATION. ALL OF THESE ARE KNOWN ISSUES WITH THE MODEL OF STEPPER MOTOR USED TO DRIVE THESE GAUGES IN MANY GM VEHICLES. MY TOTAL COST FOR REPAIR HAS BEEN IN EXCESS OF $300, NOT INCLUDING THE CURRENT OIL PRESSURE GAUGE REPAIR (STEPPER MOTORS FOR SPEEDO AND FUEL LEVEL GAUGE). I PLAN ON HAVING ALL STEPPER MOTORS REPLACED WITH THE LATEST GENERATION REPLACEMENT (SWITEC X25.168). THIS IS SOMETHING THAT GM NEEDS TO TAKE RESPONSIBILITY FOR AND CORRECT AS IT IS A VERY WIDESPREAD ISSUE. *TR

VEHICLE HAS BEEN STALLING INTERMITTENTLY AT ANY SPEED. VEHICLE HAS STALLED A TOTAL OF TEN TIMES. THE VEHICLE HAS BEEN TAKEN TO THE LOCAL MECHANIC SHOP FIVE TIMES AND THE DEALERSHIP TWICE BUT NO CODES WERE FOUND DURING TESTING. SO FAR I HAVE HAD NEW PLUGS/WIRES (TUNE-UP), NEW COIL PACK, NEW IGNITION MODULE AND NEW CRANK SENSOR, AND NEW FUEL FILTER. THE VEHICLE COMPLETELY DIES AT ANY SPEED. TOLD POSSIBILITY OF BAD FUEL PUMP BUT DEALERSHIP CANNOT BE 100% CERTAIN THIS WILL FIX THE PROBLEM. WHILE DRIVING AT 70-75 MILES AN HOUR THE CAR COMPLETELY SHUTS DOWN. IT IS A MIRACLE I HAVE NOT BEEN SEVERELY HURT OR KILLED. PROBLEMS BEGAN IN MAY 2007 AND HAVE BEEN ONGOING SINCE THEN. *TR

TL* - THE CONTACT TOOK THE 2004 CHEVROLET IMPALA IN TO HAVE A ROUTINE OIL CHANGE. THE VEHICLE HAD 37, 792 MILES. THE CONTACT WAS TOLD BY THE DEALER THAT THE COOLANT & OIL WAS LEAKING INTO THE ENGINE. THE VEHICLE WAS REPAIRED AND SHE HAS THE REPAIR ORDER. THIS IS THE FIRST INCIDENT. THE VEHICLE DID NOT GIVE ANY WARNINGS. HOWEVER, THE CONTACT'S COOLANT LIGHT TURNED ON 9/06 AND SHE HAD COOLANT ADDED.

THIS VEHICLE HAD A HEAD GASKET REPAIRED UNDER STANDARD 3 YEAR/36,000 MILE WARRANTY. WE ARE NOW TOLD WE HAVE ANOTHER HEAD GASKET OR HEAD PROBLEM AT 49,000 MILES. THIS APPEARS TO BE AN ENGINE MANUFACTURER PROBLEM OR I GOT A LEMON ENGINE FROM CHEVROLET? *JB

DEX-COOL ANTIFREEZE TURNED BROWN AND SLUDGED UP. LESS THAN ONE YEAR AND 16,200 MILES ON VEHICLE. TOOK TO DEALER AND HAD SYSTEM FLUSHED, RESERVOIR REPLACED AND NEW COOLANT ADDED. I WILL TAKE IT BACK FOR THE SAME THING EVERY YEAR. MANY PEOPLE I'VE SPOKEN TO WITH GM VEHICLES HAVE EXPERIENCED THE SAME THING WITH THIS COOLANT.

ENGINE IS CONSUMING OVER A QUART OF OIL APPROX. EVERY 1800-2000 MILES. I WAS SHOWN A BULLETIN THAT SAID THAT THERE WAS A PROBLEM WITH OIL CONSUMPTION AT THE DEALERSHIP. I BROUGHT THE CAR IN TWICE TO THEM EACH TIME THE LOW OIL LIGHT CAME ON AND EACH TIME THEY TOLD ME THERE WAS NOTHING THAT COULD BE DONE BUT TO CHECK IT EVERY DAY OR TWO AND KEEP TRACK THEN COME IN WITH MY NOTES TO SEE WHAT WAS HAPPENING. I BROUGHT THE CAR TO MY REGULAR GARAGE THE NEXT TIME THE OIL WAS LOW AND 4 MECHANICS INFORMED ME THAT THE RATE OF OIL CONSUMPTION WAS NOT REGULAR AND THAT THERE IS A PROBLEM IF IT IS NOT MAKING IT PASSED 2000 MILES BEFORE IT LOSES OVER A QUART OF OIL.

MY "LOW OIL LEVEL" LIGHT CAME ON AFTER 2000 MILES. I HAD THE OIL CHANGED, IT WAS A QUART LOW. I WAS TOLD THAT NEW VEHICLES SOMETIMES "ABSORB" OIL THE FIRST TIME. THE LIGHT CAME ON AGAIN AT 5000 MILES, THE OIL WAS OVER A QUART LOW. IT WAS IMPLIED THAT I WAS NOT RESETTING THE CHANGE OIL LIGHT PROPERLY. THE ENGINE OIL LIGHT CAME ON AT 9000 MILES. AT THIS POINT I PAID FOR AN OIL CHANGE AND AN OIL CONSUMPTION TEST WAS DONE. THE LOW OIL LIGHT CAME ON AGAIN AT 10,000 MILES. THE DEALERSHIP MADE A SERVICE APPOINTMENT, TOPPING OFF THE OIL SINCE IT WAS A QUART LOW AND I SHOULDN'T GO FOUR DAYS WITH THE OIL A QUART LOW. WHEN I RETURNED FOR THE SERVICE APPOINTMENT MY OIL LEVEL WAS ONLY 1/2 QUART LOW. THEY HAD FORGOTTEN THAT THEY TOPPED IT OFF. I HAD TO PAY FOR ANOTHER OIL CHANGE AND ANOTHER OIL CONSUMPTION (DYE TEST) WAS STARTED. I WAS SHOWN A NOTICE THAT WAS SENT TO THE DEALERSHIP REGARDING DEFECTIVE GASKETS OR SEALS ON 2004 IMPALAS. TO DATE I HAVE HAD FOUR OIL CHANGES, ALL OF WHICH THE OIL LEVEL WAS OVER A QUART LOW. I WOULD THINK THAT THERE WAS ENOGH EVIDENCE TO WARRANT THE REPAIR TO MY VEHICLE WITHOUT HAVING TO PAY FOR ANOTHER OIL CHANGE AND WAIT 2000 MILES. I AM CONCERNED THAT IF OIL IS BEING CONSUMED IT HAS TO EFFECT OTHER PARTS OF THE ENGINE. THE OIL HAS TO GO SOMEWHERE. AGAIN, I WAS TOLD THAT IT WOULD NOT CAUSE ANY EFFECT TO ANY OTHER PART OF THE VEHICLE. *AK

VEHICLE STALLED INTERMITTENTLY AT ANY SPEED. VEHICLE HAD BEEN TO DEALER ON FOUR SEPARATE OCCASIONS, AND THEY WERE UNABLE TO DUPLICATE THE PROBLEM.*AK THE VEHICLE HAS STALL A TOTAL OF EIGHT TIMES. THE VEHICLE HAS BEEN TAKEN TO THE DEALER ON FOUR OCCASIONS BUT NO CODES WERE FOUND DURING TESTING. *NM

ALL PROBS WITH 2004 IMPALA SS STARTED AFTER 3 MONTHS OF PUCHASE DATE. THERE WERE LESS THAN 3,000 MILES ON CAR. 1ST INCIDENT - WHILE MAKING RIGHT TURN AT 20 MPH, CAR DIED 1/2 WAY THROUGH TURN. THE STEERING WHEEL LOCKED AND ENDED UP GOING INTO ONCOMING TRAFFIC. LUCKILY MADE IT TO OPPOSITE SIDE OF ROAD W/ HARM. CAR WOULDNT START AT ALL. DEALERSHIP SERVICE DEPT. REPLACE CRANK SHAFT POSITION SENSOR. 2ND INCIDENT - APPROX 3 WEEKS AFTER 1ST, I WAS STOPPED TO DROP PASSENGER OFF, CAR STARTED TO SHAKE AND IDLE WAS HIGH, 2 SECONDS LATER CAR DIED. CAR RESTARTED THIS TIME, DRIVING HOME ABOUT 35MPH CAR DIED IN HEAVY TRAFFIC, STEERING LOCKED AND HAD TO STRUGGLE TO GET CAR OVER TO SIDE OF ROAD. CAR WOULD NOT RESTART THIS TIME. DEALERSHIP SERVICE DEPT AGAIN REPLACED THE CRANK SHAFT POSITION SENSOR. 3RD INCIDENT - GOT THE CAR BACK ON A FRIDAY AFTERNOON, THE CAR DIED AGAIN WHILE DRIVING BY SATURDAY NITE. DEALERSHIP SERVICE DEPT LOOKED A LITTLE FURTHER THAN CRANK SHAFT POSITION SENSOR THIS TIME AND REPAIRED LOOSE PIN CONNECTIONS IN IGNITION COIL MODULE CONNECTOR. 4TH INCIDENT - 2 MONTHS AFTER ALL THIS, CIGARETTE LIGHTER DOESNT WORK, LIGHTS DIM WHEN POWER WINDOWS PUT UP, DASH BOARD SENSOR THAT GETS OFF WHEN LOW FUEL LIGHT/ LOW TIRE PRESSURE LIGHT COMES ONDOES NOT RESET. CAR STILL FEELS SLUGGISH. LOUD SCRATCHING NOISEOCCURS WHEN WHEELS TURNED ALL THE WAY IN ONE DIRECTION. EVERYTHING FIXED B/C OF BLOWN FUSE. SCRAPING NOISE COMING FROM LOOSE CLIP IN TIRE WHEEL WELL. DEEALERSHIP STATED CAR WAS RUNNING FINE AND THERE WAS NO PERFORAMANCE PROBLEMS. THIS HAS HAPPENED OVER THE LAST 6 MONTHS. CAR PRESENTLY HAS 4500 MILES ON IT. OH AND CHEVROLET ROADSIDE ASSISTANCE ABSOLUTELY HORRIBLE. AND THEN TO TOP EVERYTHING OFF THE DEALERSHIP MAKES IT SEEM LIKE ALL OF THESE PROBLEMS ARE CAUSED BY THE DRIVER, BY ASKING WELL WHAT GAS DO YOU USE AND HOW FAST DO YOU DRIVE ON THE HIGHWAY. THIS CAR IS AN IMPALA SS. THE CAR IS SUPPOSED TO BE BUILT FOR PERFORMANCE. *AK
