2008 Chevrolet Tahoe Cruise Control Problems

GAS ENGINE RUN AWAY CHECK ENGINE LIGHT ILLUMINATED WITH P0069, P0430 (EMISSIONS CODES) ENGINE UNCONTROLLABLY REVVED TO MAXIMUM 6000 RPM (MAX THROTTLE)WHILE IN DRIVE GEAR FROM AUTOSTOP RESUME.. CRUSE CONTROL NOT ENABLED SLIGHT UPHILL GRADE REQUIRED ENGINE TO BE SHUT OFF WITH KEY SAME DAY AS FIRST EVENT WHILE IN DRIVE GEAR FROM AUTOSTOP RESUME WITH CRUSE CONTROL ENABLED AT 25 MPH ENGINE UNCONTROLLABLY REVVED TO MAXIMUM 6000 RPM WAS ABLE REGAIN CONTROL OF ENGINE RPM BY SHUTTING OFF CRUSE CONTROL .. (SOMETHING IN COMMON WITH THE FIRST TIME ) SLIGHT UPHILL GRADE UNCONTROLLED HIGH ENGINE RPM FROM AUTOSTOP RESUME STILL HAPPENING AFTER REPLACEMENT OF THE MAP SENSOR ... I SEE AS MUCH AS 2,000 TO 2500 RPM FROM AUTOSTOP RESUME... THIS IS NOT NORMAL IT SHOULD BE STARTING AT 1200 TO 1500 RPM.. NORMAL ENGINE STARTS ARE AT 1100 RPM

WHEN DRIVING AROUND AND AT A STOP LIGHT THE ENGINE WILL GO INTO AUTO STOP. WHEN APPLYING PRESSURE TO GAS PEDAL THE VEHICLE WILL HESITATE AND THEN LURCH FORWARD. VEHICLE WILL ALSO GET A HIGH IDLE BETWEEN 1500 RPM AND 2200 RPM AND FLUCTUATE BETWEEN THOSE RPMS. ALSO WHEN IDLING BELOW 1,000 RPMS THE ENGINE WILL REV UP AND DOWN AS IF PRESSURE IS BEING APPLIED TO THE GAS PEDAL BUT THERE IS NO PRESSURE BEING APPLIED AT ALL. BEEN HAVING THIS ISSUE FOR QUITE SOMETIME AND I FIGURED IT WAS JUST SOME BAD FUEL BUT IT HAS BEEN CONSISTENT. ALSO HAVE NO LIGHTS ILLUMINATED ON THE DASH, NO CHECK ENGINE LIGHTS OR ANYTHING. I HAVEN'T TAKEN TO DEALER YET BECAUSE I AM WAITING ON THE SUPPLIES FOR THE AIR BAG RECALL SO THEY CAN WORK ON THE VEHICLE WHILE REPLACING THE AIR BAG. *TR

TL* THE CONTACT OWNS A 2008 CHEVROLET TAHOE. WHILE DRIVING APPROXIMATELY 75 MPH, THE BRAKE PEDAL WAS DEPRESSED BUT THE VEHICLE FAILED TO DECELERATE. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THROTTLE POSITION SENSOR FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 145,000.

WHILE TRAVELING OUT OF TOWN STABILITRAC DISABLED ENGINE POWER REDUCED ON THE HIGHWAY. I HAD TO PULL OVER TO THE SHOULDER SINCE SPEED WAS REDUCED. I HAD TO TURN OFF VEHICLE FOR A FEW MINUTES TO LET THE ECM RESET THE FAULT. I DISTRACTED DRIVER REARENDED THE VEHICLE WHEN I WAS STRANDED WITH MY FAMILY INSIDE THE VEHICLE.

TL* THE CONTACT OWNS A 2008 CHEVROLET TAHOE HYBRID. THE CONTACT STATED THAT WHILE DRIVING AT 40 MPH, THE VEHICLE ACCELERATED INDEPENDENTLY WITHOUT WARNING. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 129,000.

AROUND FEBURARY OF THIS YEAR MY VEHICLE BEGIN TO IDLE OUT OF CONTROL AND WAS ATTEMPTING TO GUN OFF EVERTIME I TRIED TO PUT IT IN DRIVE, ACCORDING TO GM THEY WERE ALREADY AWARE OF THE ISSUES AND SAID THEY HAD AN EXTENDED WARRANTY ON THE THROTTLE BODY FOR MY 2008 CHEVY TAHOE. MY CAR DID EXACTLY WHAT GM SAID IT WOULD DO TO CONFIRM IT WAS THE THROTTLE BODY BUT THE GM SERVICE DEPARTMENT DENIED THE ISSUE CLAIMING IT WAS A LOOSE VACUM HOSE AND WOULD NOT REPLACE THE THROTTLE BODY. MY VEHICLE STILL DOES NOT OPERATE AS IT SHOULD WHICH I KNOW IS DUE TO THE THROTTLE BODY ISSUE. THOUSANDS OF OWNERS HAVE CONFIRMED THE SAME ISSUE AND OBVIOUSLY GM KNOWS ABOUT THE ISSUES BUT CHOOSES TO GO AROUND IT BY CALLING IT AN EXTENDED WARRANTY WHICH MAKES THE REPLACEMENT CONDITIONAL. I AM 100% SURE THAT I AND MILLLIONS OF TAHOE OWNERS KNOW THIS SHE BE A RECALL AND NOT A SO CALLED EXTENDED WARRANTY TO GET AROUND THE EXPENSE OF MAKING A RECALL. WHEN THE ISSUE OCCURED I WENT FLYING DOWN THE FREEWAY WITH MINIMAL ABILITY TO SLOW THE VEHICLE DOWN, I HAD TO DRIVE MY VEHICLE TO THE SHOP BY RIDING MY BREAKS BECAUSE THE VEHICLES THROTTLE BODY WOULD NOT LET THE TRUCKS RPM GO BELOW X3000. GM IS CONTINUING TO IGNORE THIS SERIOUS ISSUE AND WILL UNTILL SOMEONE DIES INSTEAD OF TAKING RESPONSIBLILTY AND MAKING THE RECALL TO PREVENT THE LOSS OF LIFE. *TR

WHILE DRIVING VEHICLE COMPLETELY STALLS NO ELECTRICAL NOT EVEN HAZARD LIGHTS. I WAS DRIVING AND RADIO STARTED TO STATIC AND THEN CAR STALLED WAS NOT ABLE TO TURN ON HAZARDS MAKING IT VERY DANGEROUS AS OTHER VEHICLES WERE NOT ABLE TO SEE THAT I WAS STALLED AND GOT VERY CLOSE TO HITTING MY TRUCK HAD TO CALL FOR HELP AS I WAS SITTING IN INTERSECTION HAD NO WAY OF TELLING THEM I WAS UNABLE TO MOVE HAD TO OPEN MY DOORS TO CALL ATTENTION TO DRIVERS. A DAY BEFORE I NOTICED THAT PROBLEM BEGAN WHEN I PARKED VEHICLE AND IGNITION KEY TURNED OFF ALL ELECTRICITY WILL QUICKLY SHUT OFF INCLUDING RADIO. WHEN AT A NORMAL TIME RADIO WOULD STAY ON UNTIL DOOR OPENED. THIS INCIDENT HAS HAPPEN TO ME 3 TIMES ALREADY. I HAVE HAD FULL BODY THROTTLE REPLACED, BATTERY AND GROUND CABLES REPLACED AND STILL NOT FIXED VEHICLE ALSO SHAKES ALOT AT TIMES WHEN STOPPED AT INTERSECTION. *TR

TL- THE CONTACT OWNS A 2008 CHEVROLET TAHOE. THE CONTACT STATED WHILE DRIVING APPROXIMATELY 30 MPH THERE WAS STATIC COMING FROM THE RADIO AND THEN THE VEHICLE STALLED. THERE WERE NO WARNING LIGHTS ON THE INSTRUMENT PANEL. THE CONTACT WAS ABLE TO RESTART THE VEHICLE. THE STATIC FROM THE RADIO ALSO CAUSED THE ELECTRIC WINDOWS TO OPEN AND CLOSE INTERMITTENTLY. THE FAILURE WAS DIAGNOSED BY THE DEALER WHO STATED THAT THE FULL BODY THROTTLE NEEDED TO BE REPLACED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 76127. RK

AFTER GETTING THE REQUIRED SOFTWARE UPDATE FROM GM, MY 2008 HYBRID TAHOE HAS HAD MULTIPLE EPISODES OF UNCONTROLLED ACCELERATION WHEN DRIVING ON CRUISE CONTROL. WHEN USING CRUISE CONTROL AT AROUND 30MPH AND WHEN REACHING AN INCLINE THAT REQUIRES SLIGHT ACCELERATION TO MAINTAIN SPEED, THE VEHICLE "FLOORS" ITSELF, DOWNSHIFTS AND ACCELERATES AGGRESSIVELY. I'VE HAD TO JUMP ONTO THE BRAKES TO AVOID LAUNCHING FORWARD. IF I HAD BEEN IN A SITUATION WHERE I WAS CLOSE TO ANOTHER VEHICLE OR OTHER OBJECT, OR IF I HAD NOT BEEN PAYING CLOSE ATTENTION, THE TRUCK COULD EASILY HAVE ACCELERATED RAPIDLY CAUSING A CRASH. *TR
