2015 Chevrolet Volt

The passenger presence sensor in the front passenger seat is malfunctioning and spare parts to replace it are not available from the manufacturer. The Chevrolet dealership has inspected and verified this issue, and the system is available for inspection upon request. This is the same issue that NHTSA investigated in the 2013 model described below. This sensor failure results in a check airbag signal and prevents the deployment of the passenger frontal and knee air bags, posing risk of serious injury to passengers. The PSS may develop a malfunction due to bunching of the sensor mat in the seat trench. The bunching of the sensor mat could cause the mat to repeatedly fold in the same location. Over time, the repeated folding can cause an increased resistance in the sensor mat. An increased resistance in the PSS sensor mat is detected as a fault in the air bag system diagnostic. If this fault is detected, a diagnostic trouble code will be stored in the air bag control unit and the air bag MIL will illuminate. Further, if the fault is detected, the passenger frontal and knee air bags will be suppressed in a crash of sufficient severity to warrant a commanded deployment regardless of the nature of size of the occupant of the front passenger seat.

Driving 75mph with cruise control during moderate traffic on freeway about 30 minutes after starting the car, my Volt shut off. There was a jolt of the car that felt like strong breaking and my dash along with everything electrical shut off for about 2 seconds then kicked back on with "Service Theft Deterent" on dash. I could not break or steer the vehicle. I had to come to a rolling stop on shoulder of freeway. Luckily I was in toll lane #1 next to the shoulder or I might have been in a wreck with other cars. I have a check engine light on now and a scheduled appointment at Chevy dealer made prior to today for tomorrow. I have had an issue with my Volt not charging at home/work for a few weeks. No breakers pop, the vehicle just wont complete the charge. The battery was replaced a week ago, driven over 250 miles with new battery, and it is still not charging properly. I have no messages on my vehicle regarding battery, engine, etc. Just the check engine light lit up.

TL* THE CONTACT OWNS A 2015 CHEVROLET VOLT. THE CONTACT STATED THAT THE AIR BAGS WARNING LIGHT ACTIVATED INTERMITTENTLY WHILE ACCELERATING OR DURING HARD BRAKING CONDITIONS. THE VEHICLE WAS TAKEN TO BERGSTROM CHEVROLET OF MIDDLETON (3605 TRIBECA DR # 101, MIDDLETON, WI 53562, (800) 353-1150) TO BE DIAGNOSED. THE CONTACT WAS INFORMED THAT THE SEAT BELT PRETENSIONER NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED TWICE. THE VEHICLE WAS TAKEN BACK TO BERGSTROM CHEVROLET OF MIDDLETON, WHERE IT WAS DIAGNOSED WITH NEEDING THE WIRING HARNESS TO BE REPLACED. THE VEHICLE WAS NOT YET REPAIRED. THE MANUFACTURER WAS NOT INFORMED OF THE FAILURE. THE FAILURE MILEAGE WAS UNKNOWN.

DRIVING ON 55 MPH STRAIGHT TWO LANE ROAD WHEN CAR AHEAD SLOWED. TO RECOVER ENERGY TO THE BATTERY, DROPPED FROM "D" TO "L" IN GEAR SELECTION RATHER THAN USING BRAKES (WAS PLENTY OF DISTANCE, BUT NOT ENOUGH TO COAST). CAR IN FRONT TURNED OFF TO RIGHT. I ADVANCED SELECTOR TO DRIVE, BUT OVERSHOT INTO NEUTRAL. REALIZED MY ERROR WHEN PRESSING ACCELERATOR YIELDED NO SPEED INCREASE. PUT SELECTOR INTO "D", VERIFIED VISUALLY AND PRESSED ACCELERATOR WITHOUT RESULT. VERIFIED AGAIN VISUALLY THAT SELECTOR IN D. ADVANCED DELIBERATELY INTO N, THEN BACK TO D, THEN REAPPLIED ACCELERATOR WITH FUNCTIONAL RESULT THIS TIME. I AM A PE WITH SIEMENS VDO, RETIRED. SINCE VEHICLE IS SINGLE SPEED "TRANSMISSION", I ASSUME COMPUTER GLITCH

THIS VEHICLE HAS 84,500 MILES ON IT AS OF JUNE 2020. I AM THE ORIGINAL OWNER. DURING A STATE MANDATED SAFETY INSPECTION IN JUNE 2020, BOTH OEM OUTBOARD REAR BRAKE SHOES WERE FOUND TO HAVE SEPARATED INTO 2 PIECES AND FAILED INSPECTION. THE SEMI-METALLIC BRAKE PAD HAD SEPARATED FROM ITS METAL BACKING PLATE. I BELIEVE THE TWO PARTS OF THE BRAKE PAD ASSEMBLY ARE HELD TOGETHER WITH AN ADHESIVE, AND THE ADHESIVE FAILED ON BOTH PADS IN SIMILAR FASHION. AN INTERNET SEARCH REVEALED THAT THIS BRAKE PAD SEPARATION HAS OCCURRED TO A NUMBER OF CHEVY VOLT VEHICLES. REGENERATIVE ELECTRIC BRAKING MEANS THAT THE HYDRAULIC BRAKES (AND THUS THE BRAKE PADS) ARE RARELY USED ON THIS VEHICLE. THE BRAKES HAD NEVER BEEN SERVICED ON THIS VEHICLE, SO THE PADS WERE OEM. I HAVE RETAINED THE BRAKE PADS FOR REVIEW OR ANALYSIS.

WHEN IT RAINS OR THE CAR GETS WET, THERE WILL BE WATER THAT RUNS DOWN FROM THE UPPER RIGHT CORNER OF THE PASSENGER SIDE INTO THE FLOORBOARD CAUSING THE CARPET TO GET SOAKING WET AS WELL AS THE ELECTRICAL COMPONENTS THAT RUN UNDERNEATH THE CARPET. IT APPEARS THE SEALANT UNDER THE HOOD AND UNDER THE COWL IS FAULTY CAUSING WATER TO LEAK INTO THE CAB. THIS OCCURS WHEN THE CAR IS STATIONARY OR IN MOTION. THIS IS A FACTORY DEFECT AND NEEDS TO BE CORRECTED, NOT TO MENTION THAT THE ELECTRICAL COMPONENTS GETTING WET COULD POTENTIAL CAUSE A FIRE OR HAZARDOUS SITUATION. ALSO I TOOK IT BY A CHEVY DEALERSHIP BUT THEY COULDN'T FIND ANYTHING IN THE ALLOTTED DIAGNOSTIC TIME WITHOUT HAVE TO CHARGE ME MORE TO REMOVE SEATS AND CARPET. I DECLINED.

WHILE DRIVING ON THE HIGHWAY THE INSTRUMENT CLUSTER WENT BLANK AND TURNED OFF. THIS HOUSES INFORMATION LIKE WARNINGS, SPEED, FUEL LEVEL, BATTERY LEVEL, TRACTION, NAVIGATION, ODOMETER, LIGHT SIGNALS AND OTHER INFORMATION. THIS IS A HUGE SAFETY ISSUE WHILE TRAVELING DOWN THE ROAD AND LOSING YOUR ABILITY TO LOOK AT THE SPEED OR IF YOUR BLINKERS OR LIGHTS ARE ON.
