2014 Chevrolet Volt Complaints

From Diagnostic report: CODE B0074, Airbag Front Passenger Presence Module Replacement SHORTED. PART #22968437

Our 2014 Chevy Volt began to rarely give an audible chime with a: "Service Airbag" message on the Driver Information Center display, as well as the "Passenger Airbag" overhead panel display showing "On"-"Off"-"On", spontaneously back in 2018. Again, this was rare, but concerning. This became somewhat more common in the months that followed and is now a common annoyance on every drive. Because of personal circumstances, as well as the Coronavirus Pandemic, we have not driven this vehicle much over the past couple of years, and we have not taken the car in for service. It has not yet been inspected by any other entity other than myself. The alarms happen whether the passenger seat is occupied or not. I have read on the GM-Volt online forum that this is likely caused by a defective passenger detection pad in the passenger seat, but I have personally checked the seat wiring harness and connector, and they appear to be nominal. Obviously, having an inoperative passenger airbag system is...

Several times a the passenger side airbag with or without a passenger will say it has an issue and a warning will pop up on the dash for a few seconds and then go away. It has been doing this since I got the car used over 2 years ago. I'm not sure if this means the airbag will deploy or not. It simply says airbag warning then goes away. I took it to the chevy dealership and they didn't find any issue.

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.

Service airbag is turning on.
