NHTSA Complaint #11679207 — 2018 CHEVROLET VOLT

When shift lever is moved to Park, the car often does not recognize it is in Park and can't be shut down. It takes a lot of time of moving the selector in and out of Park to finally get the car to recognize it is in Park. During an occasion when the car would not go into Park, the car ran for hours while the driver was at work. This seems to be a known issue (micro switch) with this model. This is available for inspection upon request. Safety is at risk because this condition leads to not being able to shut the car down, which leads to the potential for a dead battery and getting stranded. While I have not yet had my car's problem reproduced or confirmed by a dealer or independent service center, there is a lot of evidence in online forums of the prevalence of this problem. The vehicle/component has not yet been inspected by the manufacturer, police, insurance representatives or others. There weren't any warning lamps, messages or other symptoms of the problem prior to the failure as long as we've owned the vehicle. We purchased this vehicle less than a week ago, on August 2, 2025. The issue presented itself once on our test drive and again intermittently in the six days we've owned the vehicle.
