When shifted into park, persistent error message that car was not in park. Unable to shut off the car despite numerous manipulations of shift. Few similar preceeding incidents were resolved by shift to drive then back to park. Goes to dealer tomorrow. Car running endlessly is dangerous. What if I could not stay with the car, or the car was on the local ferry. No one has inspected it yet. First time problem occured was in November 2024. Most recent more serious problem occured Friday. I am afraid to use the car since, and have not driven it since.

The dealer fixed it in our recollection. 2) On [XXX], I was driving the car out of a Detroit Convention Center parking lot, going up the ramp when the car, with no warning, completely lost power and stopped. The message on the display said "Powertrain loss" or "Powertrain lost." I wish I had taken a photo of it, but I was panicked. Cars were backed up behind me on the ramp out of the parking garage, honking and having to back up. I tried turning the car off and on, googling the problem, and was about to call a tow truck when after 12-13 minutes, I was…

While driving home one evening, the power steering suddenly failed. A warning message displayed to service the power steering. It became very difficult to steer the car.

Fortunately I did make it home safely and shut the car down. I made an emergency repair appointment for the next day at a Chevrolet dealership. In the morning the power steering was back. The car was inspected at the dealership. They told me a software update was needed and they charged me $450 to…
