2014 Chevrolet Volt Electrical Problems

Your car suddenly surged forward and hit your garage wall while you were slowly backing in, even though you were only lightly braking and not accelerating. Your car had been showing a "Propulsion Power is Reduced" warning and wasn't holding an electric charge, but the malfunction indicator light never came on, so you thought it was safe to drive based on the owner's manual. The unexpected surge caused severe damage to your garage, and your insurance company totaled the vehicle.

While driving at 55 mph and attempting to merge, your Volt suddenly hesitated and shut off in traffic. The dealer diagnosed a failed battery as the cause. This is a serious safety concern since the engine unexpectedly died while you were actively driving. The battery will need to be replaced to restore normal operation.

Your car loses power and jerks suddenly while driving, especially on hills or the freeway, which feels unsafe and unpredictable. The dealership has been unable to reproduce or fix the issue despite multiple visits, and you've discovered this is a known problem affecting other Volt owners. The problem also involves a high voltage electrical issue and a coolant sensor that gives incorrect readings. Resolving this will likely require diagnostic testing of the electrical system, high voltage battery connections, and engine sensors to identify the root cause of the power loss.

Your Volt has stalled multiple times when switching from battery power to the gasoline engine, leaving you unable to drive. The lithium battery isn't charging properly, which causes the engine to shut down once the battery is depleted. This has happened at least three times since February 2022, and despite diagnostic service and error code clearing at dealerships, the problem persists. The repair will likely involve diagnosing and replacing the battery management system, charging components, or the hybrid power control module.

Your 2014 Volt lost all power and stalled without warning while driving at 40 MPH. An independent mechanic diagnosed a battery failure as the cause. The manufacturer informed you that the free replacement warranty period had already expired, so you're responsible for the repair cost.

Your car's main battery pack suddenly stopped working while you were driving on the highway with no warning signs beforehand. This left you without power while driving. The issue may require battery pack replacement or diagnosis of the charging system.

GM has disabled the OnStar feature on your 2014 Volt because it uses older 2G cellular connectivity. Canadian owners were offered a free upgrade to 4G connectivity to restore the feature, but U.S. owners have not received the same option. GM has the technical capability to perform this upgrade, as documented in their service bulletin, but is not offering it to American customers.

The contact owns a 2014 Chevrolet Volt. The contact stated that while operating the vehicle during an electrical storm the power would shut off causing the vehicle to become inoperable. On one occasion the power shut off causing the vehicle to roll into the rear of a second vehicle causing damage to the bumper. No injuries were reported and no police report was taken. The vehicle was taken to the local dealer who was unable to duplicate the failure and no repairs were performed. The manufacturer was also notified of the failure. The failure mileage was 46,000.

TL* THE CONTACT OWNS A 2014 CHEVROLET VOLT. WHILE DRIVING IN THE ELECTRIC MODE, THE VEHICLE'S BATTERY VOLTAGE SUDDENLY FAILED AND THE PROPULSION SYSTEM WARNING INDICATOR ILLUMINATED. THE VEHICLE WENT INTO ITS BACKUP MODE, WHICH WAS THE USE OF THE FUEL GENERATOR, AND LOST POWER. THE CONTACT TOOK THE VEHICLE TO DYER CHEVROLET FORT PIERCE (LOCATED AT 4200 S US HWY 1, FORT PIERCE, FL) WHERE THE HPCM2 SYSTEM WAS REPROGRAMMED, WHICH RELATED TO THE HYBRID PROPULSION SYSTEM. THE FAILURE OCCURRED. THE CONTACT STATED THAT THE FAILURE WAS SIMILAR TO NHTSA CAMPAIGN NUMBER: 18V397000 (HYBRID PROPULSION SYSTEM). THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 105,000. *CW THE CONSUMER STATED THE VEHICLE HAS BEEN SOLD.*JS

CAR TELLS ME THAT THE AIRBAG NEEDS TO BE SERVICED EVERY TIME THE CAR TURNS ON AND CONTINUES TO ALERT ME AS I DRIVE, EVEN AFTER I ACKNOWLEDGE THE ERROR. APPARENTLY THE FRONT PASSENGER DETECTOR FOR TURNING ON THE AIRBAG MUST BE REPLACED. THE PREVIOUS OWNER SAYS HE'S DRIVEN WITH THIS PROBLEM FOR OVER A YEAR. OVER $600 TO REPLACE. FROM READING FORUMS ONLINE, I SEE THAT THIS IS NOT AN UNCOMMON PROBLEM. THE PART SHOULD BE RECALLED.

THE 120V CHARGING CORD THAT CAME WITH THE VOLT HAS CRACKED AND FRAYED, EXPOSING ELECTRICAL WIRES TO THE ELEMENTS AND CREATING A FIRE HAZARD. SEE PHOTO OF CORD CONDITION. THE CHARGER IS A NECESSARY ELEMENT TO USING AN ELECTRIC-HYBRID VEHICLE. WE ASKED THE CHEVY DEALER FROM WHOM WE BOUGHT THE VOLT (SEE BUSINESS CARD PHOTO) TO PROVIDE A REPLACEMENT CHARGER, AND THEY REFUSED TO. THIS EQUIPMENT IS AN UNACCEPTABLE FIRE HAZARD, AND ITS CONDITION SHOULD NOT HAVE RESULTED FROM NORMAL WEAR AND TEAR.

STARTING UP THE CAR IN THE MORNING, THE DISPLAY PANEL WENT DARK. I TURNED OFF THE VEHICLE AND TRIED STARTING UP THE VEHICLE AGAIN WITH NO CHANGE. THE DISPLAY PANEL IS DARK. I AM NOT ABLE TO SEE GAS INFORMATION, BATTERY INFORMATION, SPEED, AND TURN SIGNALS.

THE ELECTRIC HEATING SYSTEM FAILED ON MY VOLT WHICH DISABLED THE WINDSHIELD DEFROSTER, CREATING A DANGEROUS VISIBILITY SITUATION. THE VOLT HAS TWO HEATING SYSTEMS, THE TRADITIONAL WASTE HEAT FROM THE ENGINE'S COOLING SYSTEM AND AN ALL-ELECTRIC RESISTOR PACK. WHEN THE CAR RUNS IN ALL-ELECTRIC MODE, THE ENGINE DOES NOT ENGAGE AND THE TRADITIONAL HEATING SYSTEM IS INEFFECTIVE. THERE IS A MODE THAT WILL OPERATE THE ENGINE WHILE THE BATTERY STILL HAS A CHARGE, BUT THE CAR STILL RUNS PRIMARILY ON BATTERY POWER AND ONLY RUNS THE ENGINE TO MAINTAIN A CERTAIN CHARGE LEVEL. THERE IS NO BACKUP MODE TO FORCE THE ENGINE TO RUN IF THE ELECTRIC HEATER FAILS. I PARK OUTDOORS OVERNIGHT IN A PARKING LOT. THIS MORNING, DESPITE ENGAGING THE VEHICLE MODE THAT OPERATES THE ENGINE TO SUSTAIN THE BATTERY CHARGE LEVEL, THE ENGINE DID NOT OPERATE OFTEN ENOUGH TO GENERATE ENOUGH HEAT TO DEFROST/DEFOG THE WINDSHIELD UNTIL TRAVELLING NEARLY 2 MILES. YOU CAN'T SIT AND WAIT FOR THE ENGINE TO HEAT UP BECAUSE THE ENGINE STOPS WHEN THE VEHICLE IS STATIONARY.

TL* THE CONTACT OWNS A 2014 CHEVROLET VOLT. WHILE DRIVING 25 MPH IN BATTERY MODE, THE BATTERY EMPTIED AND THE VEHICLE SWITCHED TO GAS MODE. THE VEHICLE EMITTED A LOUD NOISE AND LOST ACCELERATION. THE CONTACT STATED THAT THE ON STAR SYSTEM ACTIVATED AND INDICATED A SYSTEM FAILURE. THE CONTACT WAS ABLE TO COAST THE VEHICLE ONTO THE ROAD SHOULDER. THE VEHICLE WAS TOWED TO BEDARD BROS (391 SOUTH STATE ROAD, CHESIRE, MA 01225, (413) 743-0014) WHERE IT WAS DIAGNOSED THAT THE ELECTRONIC CONTROL MODULE (PART NUMBER: 12670036) FAILED. THE DEALER REPLACED THE ELECTRONIC CONTROL MODULE AND REPROGRAMMED THE VEHICLE IMMOBILIZER. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS 33,509.

WHEN USING THE TURN SIGNAL WITH THE RADIO BARELY ON I CANNOT HEAR THE TURN SIGNAL INDICATOR AT ALL. THE TURN SIGNAL SOUND IS EXTREMELY LOW. TODAY I LEFT IT ON ACCIDENT AND A VEHICLE PULLED OUT IN FRONT OF ME ASSUMING I WAS TURNING, HOWEVER I WAS NOT. THIS COULD HAVE CAUSED A FATAL ACCIDENT IF HE DID PULL OUT, THE VEHICLE STOPPED JUST INCHES BEFORE BEING IN THE ROAD. IF THE BLINKER INDICATOR IS THROUGH THE VEHICLE AUDIO SYSTEM, IT NEEDS TO BE INCREASED. I HAVE LEFT MY BLINKER ON MULTIPLE TIMES >10.

SERVICE AIRBAG LIGHT WARNING. REPAIR SHOP SAYS THE PASSENGER SIDE SEAT 'PASSENGER PRESENCE MODULE' NEEDS TO BE REPLACED. WHAT IS THE SAFETY RISK OF NOT PAYING THE $500?

A USED CHEVY VOLT.IT CAME WITH A LEVEL 1 CHARGER. BASIC 110 V TAKES 8 HOURS TO CHARGE 18KVH BATTERY. THIS CHARGER WAS REPAIRED FROM THE LOOKS OF IT.I USED IT FOR A FEW TIMES AND IT BURNT. LUCKILY IT WAS NOT NEAR ANY FLAME ABLE MATERIAL, OR IT MAY HAVE CAUSED FIRE.

TL* THE CONTACT OWNS A 2014 CHEVROLET VOLT. STARTED CAR WHILE PARKED IN GARAGE AND THE INSTRUMENT PANEL BECAME INOPERABLE WITHOUT WARNING. AS A RESULT, THE CONTACT WAS UNABLE TO DETERMINE THE AMOUNT OF FUEL THAT WAS INSIDE THE VEHICLE AND THE SPEED. THE VEHICLE WAS NOT DIAGNOSED NOR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND TOLD ME TO GO TO A DEALERSHIP WHICH WILL RESULT DIAGNOSTIC FEE. THE FAILURE MILEAGE WAS 61,000.

THE SCREEN THAT DISPLAYS SPEED, FUEL REMAINING, ETC GOES DARK AT RANDOM TIMES WHILE DRIVING. IT HAPPENS MOST OFTEN WHEN I FIRST TURN ON THE CAR AND LASTS FOR SEVERAL MINUTES. OCCASIONALLY IT HAPPENS WHEN I HAVE BEEN DRIVING FOR A WHILE.

AIR BAG SENSOR AND COMPUTER SYSTEM MALFUNCTION THE DRIVER SIDE SENSOR AT TIMES MALFUNCTION AND SO THE SOFTWARE DISABLE THE AIR BAG SYSTEM AS A WHOLE. THE SERVICE AIR BAG MESSAGE COMES ON FOR FEW MINUTES AND THEN DISAPPEARS ASSUMING EVERYTHING IS OK. TOOK IT TO THE DEALER AND THEY INFORMED ME THAT I NEED TO CHANGE WHOLE AIRBAG SENSOR KIT AND WOULD COST ME MORE THAN 1300 DOLLARS. THIS SHOULD BE A RECALL AS THIS RELATES TO SAFETY

CHEVY VOLT WAS DRIVEN INTO THE GARAGE WITH 10 MILES LEFT ON THE BATTERY, THE CAR WAS PLUGGED INTO THE ELECTRIC CHARGER FOR OVER NIGHT CHARGE. IN THE MORNING IN THE ATTEMPT TO TURN ON THE CAR A MESSAGE APPEARED STATING. "NOT ABLE TO CHARGE" "BATTERY RANGE 0 MILES" "CHARGING OVERRIDE/INTERRUPT OCCURRED" MY HUSBAND CAME AND CHECKED OUT THE CAR WE PLUGGED INTO OUR 110 VOLT CHARGE TO MAKE SURE THAT IT WASN'T OUR CHARGING SYSTEM. WAITED SEVERAL HOURS STILL NO CHARGE. ON STAR WAS CALLED THEY COULD NOT COLLECT ANY DATA BECAUSE THE CAR WAS TOTALLY SHUT DOWN. SOME TIME LATER POSSIBLY THE NEXT DAY (SUNDAY) THERE APPEARED A MESSAGE. "CHARGING OVERRIDE/ INTERRUPTION A CHARGING OVERRIDE OR INTERRUPTION HAS OCCURRED DUE TO ONE OR MORE OF THE FOLLOWING EVENTS: * OVERRIDE OF CHARGING SETTINGS BY VEHICLE OWNER VIA ONSTAR. (THIS DID NOT HAPPEN) * UNINTENDED INTERRUPTION OF AC POWER KATH THE VEHICLE'S CHARGE PORT. (ALSO DID NOT HAPPEN) *INTERRUPTION OF CHARGING BY THE UTILITY COMPANY VIA ONSTAR AS AUTHORIZED BY VEHICLE OWNER. (ALSO DID NOT HAPPEN) SEE OWNER'S MANUAL FOR FURTHER DETAIL." MONDAY MORNING CAR WAS TOWED TO DEALERSHIP. DEALERSHIP ATTEMPTED TO CHARGE AND RUN TESTS TO FIND OUT WHAT HAD HAPPENED. AFTER FIVE DAYS THEY DECIDED TO ORDER A PART, NOT SURE WHAT THE PARTS ACTUAL NAME WAS, SOMETHING TO DO WITH AN ELECTRICAL STARTING MODULE. DEALERSHIP SAYS THE PROBLEM IS SOLVED, PICKING UP ON THE 6TH DAY AT DEALERSHIP. HOPING ALL IS WELL.

CHEVROLET VOLT 2014 HEAD UNIT REBOOTS WHILE VEHICLE IN MOTION (CITY STREETS AND FREEWAYS). NO USER AUXILIARY DEVICE PLUGGED IN. FH DAILY SAN LEANDRO COULD NOT IDENTIFY PROBLEM. REBOOTING OCCURED APPROXIMATELY 1 MONTH AGO AFTER MANUFACTURER RECALL REPAIR. CAR WAS LAST SERVICED 11/22/16 FOR STATED PROBLEM. HEAD UNIT REBOOTED 12/1/16 WHILE IN MOTION ON CITY STREET. HEAD UNIT PROVIDES VITAL INFORMATION INCLUDING VEHICLE OFF/ON STATUS AND AUDIBLE TONES.

IGNITION SHUT OFF ON MASSACHUSETTS TURNPIKE WHEN TRYING TO CHANGE FROM NORMAL (ELECTRIC) TO HOLD (GAS) MODE. MODE BUTTON IS TOO CLOSE TO IGNITION POWER BUTTON. I HAD TO STOP IN RUSH HOUR TRAFFIC TO PUT CAR IN DRIVE AND RESTART, COULD HAVE BEEN HIT. I CALLED ONSTAR EMERGENCY SERVICE IN THE MOMENT, BUT THEY WERE NOT AWARE OF A WAY TO RESTART THE CAR WHILE IT WAS ROLLING. DISCOVERED LATER THAT THERE IS A 3-STEP PROCESS TO RESTART THE CAR WHILE IT'S STILL MOVING, BUT IT IS COMPLICATED AND DIFFICULT TO REMEMBER WHILE PANICKING ABOUT THE DANGER OF BEING HIT. THERE IS NO AUTOMATIC WAY TO RESTART IN CASE OF ACCIDENTAL SHUT OFF. THIS SHOULD BE FIXED OR SOMEONE WILL GET HURT OR KILLED. THIS HAS HAPPENED TO ME SEVERAL TIMES ON THE HIGHWAY AND I HAVE BEEN VERY LUCKY NOT TO HAVE BEEN HIT WHILE FIGURING OUT HOW TO RESTART THE VEHICLE. I COMMUTE DAILY INTO BOSTON AND HAVE TO KEEP EYES ON THE ROAD AT ALL TIMES; WITH THE MODE BUTTON NEXT TO THE POWER BUTTON, THERE IS CONSTANT DANGER OF SHUTTING THE CAR DOWN AT PRECISELY THE MOMENT WHEN I EXPECT AND NEED TO BE ACCELERATING.

SATURDAY ON 09/5/2015 AROUND 12:00 NOON WHILE DRIVING OUR 2014 CHEVY VOLT, WHILE I WAS PASSENGER, MY WIFE WHO WAS DRIVING THE CAR SUDDENLY NOTICED THE CAR COMPUTER PROGRAM HAS GONE CRAZY AND STARTED THROWING ALL KINDS OF ERRORS STARTING WITH 1) PROGRAM CLUSTER ERROR 2) ICE MAY BE POSSIBLE 3) WASHER LEVEL LOW 4) SOME OTHER KIND SENSOR ERRORS 5) BATTERY LEVEL STARTED SHOWING ZERO ( IT WAS FULL ) 6) FUEL LEVEL WAS ZERO ( HAD OVER 1/2 TANK FUEL) 7) ODOMETER INDICATION HAD CHANGED ON ITS OWN TO KM FROM MILES 8) NO PROPER VEHICLE SPEED INDICATION.9 ) SUSPENSION NEED ADJUSTMENT ETC ALL THESE ERRORS KEPT REPEATING OVER AND OVER WHILE DRIVING CAUSING A BIG PANIC TO DRIVER AND PASSENGER (ME) BESIDES RESULTING IN DISTRACTED DRIVING. BOTH DRIVER AND PASSENGER SEAT HEATING KICKED IN ON ITS OWN. FOR A SHORT PERIOD WE WERE NOT SURE WHETHER THE VEHICLE IS MOVING UNDER OUR CONTROL OR NOT. ON THE CENTER PANEL ALSO THE INFORMATION SYSTEM WAS SHOWING ALL KINDS OF ERRORS LIKE, BATTERY WAS SHOWING EMPTY, THE AMBIENT TEMP WAS SHOWING - 27C ALTHOUGH IT WAS QUOTE HOT AT THAT TIME AND THE MILES HAD CHANGED TO L / KM ETC. LOOKS LIKE ALL THE UNITS CHANGED IN THE CAR TO METRIC ON ITS OWN. ALL THE SYMPTOMS INDICATIONS WERE SIMILAR TO THE VIDEO SOME ONE HAS ALREADY POSTED HERE AT THE BELOW YOU TUBE LINK. HTTP://WWW.YOUTUBE.COM/WATCH?V=07ZMNH5Z1GO SCARIEST PART WAS OUR VEHICLE STARTED DOING WHILE IT WAS BEING DRIVEN IT WAS LIKE CAR LOSING ITS BRAIN ( COMPUTER PROGRAM GETTING CORRUPTED ) WHILE ON ROAD. THIS SITUATION POSES A BIG SAFETY RISK TO PEOPLE. CURRENTLY AS OF TODAY 09/09/2015 VEHICLE IS STILL AT DEALERSHIP AND YET TO BE FIXED AND HANDED OVER BACK TO US. I HAVE ALREADY CALLED GENERAL MOTORS CUSTOMER SERVICE AND EXPRESSED THE SAFETY CONCERNS, BESIDES THEY EXPECT ME TO PAY IN PART TO FIX THIS. I CAN PROVIDE NHTSA MY CASE NUMBER THAT GM REPRESENTATIVE GAVE ME.

TL* THE CONTACT OWNS A 2014 CHEVROLET VOLT. THE CONTACT STATED WHILE THE BRAKE PEDAL WAS DEPRESSED, HE INADVERTENTLY TOUCHED THE IGNITION SWITCH. ALSO, THE CONTACT STATED THAT THE OPERATING BUTTONS WERE TOO CLOSE TOGETHER WHICH MAY CAUSE A CRASH. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE AND CURRENT MILEAGE WAS 700. UPDATED 9/9/14*CN THE CONSUMER STATED THE DRIVE MODE BUTTON WAS NEAR THE IGNITION POWER BUTTON. WHEN HE WAS IN THE MIDDLE LANE DRIVING, HE REACHED OVER TO CHANGE THE DRIVE MODE, HE ACCIDENTALLY PUSHED THE POWER BUTTON. THE VEHICLE DID NOT SHUT OFF, BECAUSE HIS FOOT WAS NOT ON THE BRAKE. NOW, IF HE HIS FOOT WAS ON THE BRAKE, AND THE POWER BUTTON WOULD HAVE BEEN HIT, INSTEAD OF DRIVE MODE, THE VEHICLE WOULD SHUT OFF AND COULD NOT BE RE-STARTED BY PUSHING THE BUTTON AGAIN. THE VEHICLE WOULD HAVE TO BE SHIFTED INTO NEUTRAL AND PUSH THE POWER AGAIN TO RE-START IT. UPDATED 10/21/14

I RECEIVED THE CHEVY VOLT 2/20/14 AT AROUND 10:45 AM. MY PARTNER AND I HAD A VERY IMPORTANT MEETING AT 12:30 P.M. IN JERSEY CITY, NJ SO WE LEFT DIRECTLY FROM THE DEALERSHIP IN THE BRAND NEW VOLT, 7 MILES ON THE ODOMETER. AT APPROXIMATELY 12:00 P.M. THE CAR ALARMED WITH TWO MESSAGES: 1. ENGINE NOT AVAILABLE AND 2. PROPULSION POWER REDUCED. THE ALARMS/ENGINE FAILURE CAME AT THE MOST INOPPORTUNE TIME---WHILE ON THE NEW JERSEY TURNPIKE IN A CONSTRUCTION ZONE AND NO AVAILABLE SHOULDER. WITH SEMI-TRUCKS BEARING DOWN ON US, WE LUCKILY MADE IT TO A CONSTRUCTION PULL OFF AREA AND CALLED ON STAR. ON STAR INFORMED US THE TURNPIKE IS A RESTRICTED ZONE SO THEY COULD NOT SEND ANYONE, THEY WERE HELPFUL AND GOT IN TOUCH WITH THE TURNPIKE AUTHORITY WHICH SENT A TOW TRUCK. WHILE I WAS ON THE PHONE WITH ON STAR MY PARTNER CALLED THE DEALERSHIP WHERE WE GOT THE CAR. THEY WERE HELPFUL AND CONTACTED THE DEALERSHIP WHERE THE CAR WOULD BE TOWED?MALOUF CHEVROLET. AFTER WAITING OVER 30 MIN FOR A TOW TRUCK TO ARRIVE, ALL THE WHILE FEARING I WAS GOING TO BE MOWED DOWN BY A SEMI-TRUCK ON THE SHOULDER, THE BRAND NEW VOLT, MY PARTNER AND I WERE OFF THE TURNPIKE. UPON ARRIVAL TO MALOUF WE WERE GREETED BY A MEMBER OF THEIR SERVICE TEAM, HE ASKED ME HOW MANY MILES WERE ON THE CAR. I SAID?66?, HE ASKED ?6600?, I RESPONDED ?NO! 66, THE CAR ONLY RAN FOR A LITTLE OVER AN HOUR AFTER DELIVERY!? WE NOW HAVE A LOANER FROM MALOUF AND HAVE NOT HEARD ANYTHING ABOUT WHAT CAUSED THIS CATASTROPHIC FAILURE OF THE BRAND NEW CHEVROLET VOLT. *TR
