2015 Chevrolet Volt problems

“My 2015 Chevy Volt has been experiencing ongoing mechanical and electrical issues, including random power loss, reduced propulsion warnings, and sudden vehicle shutdowns with no prior indication. These problems pose a serious safety concern, as the car can lose power unexpectedly while driving. Despite these issues, GM has refused to service the vehicle or unlock necessary components because they no longer manufacture or support the required parts. As a result, I am left with an unsafe and unreliable vehicle with no available remedy from the manufacturer. This is forcing me to trade in the vehicle at a loss”

“The vehicle experienced a catastrophic charging system failure. When connected to the wall charger, the charge port becomes hot to the touch within seconds. The charger connector has now cracked from heat stress, and the wall charger itself previously melted due to electrical backfeed from the vehicle. The vehicle refuses to charge at all. This appears to be a thermal event and fire-risk safety defect involving the onboard charger, wiring harness, or battery management system. Insurance refused coverage due to the nature of the electrical failure. The vehicle is unsafe to charge or operate.”

“This car is connected to Bouncie a device that detects when a car turns on and off, the speed, if break or acceletor are stepped on forcefully and any trips. Recently the device is detecting the engine is turned off but the car is showing no signs of struggling and its in full motion. This is new, I've tested the device in another car for two weeks hoping it was the device but I had no issues on the other vehicle. The images is just one of several occasions. The image shows green dot where car starts and red where car is turned off. However, I never turned off my car at the Demaree Rd that day. I feel like the car is losing power and starts back up while in motion.”

“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…”

“A "service brakes" warning came up when I was parked in a parking lot and immediately afterwards the brakes stopped working when I was reversing in the parking lot and I almost backed up into another car. I had my car towed to Paradise Chevrolet and they diagnosed the problem as a faulty "brake pressure modulator valve" (BPMV) that needs to be replaced. I saw that there is a recall for the 2012 Chevy Volt for the same issue, faulty BPMV.”

“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”
