When I shift my vehicle into park and hit the button to shut it off, a "shift to park" message appears on the DIC screen. I then am required to start my vehicle again, shift into gear, and then put it back into park and attempt to shut the vehicle off again. It has taken me up to 15 minutes to be able to get it to recognize that my vehicle is in park and for the message to not pop up. If I get out of the car while the message is still on the DIC screen, I cannot lock my vehicle and it drains the battery. I contacted my local Chevrolet dealer and they are saying that although this is a known issue which has had more than one GM Service Bulletin on this issue which includes my year and model, there is not an actual recall for this, so I have to pay out of pocket, because my bumper to bumper warranty expired at 36,000 miles and I am currently just shy of 39,000 miles. Of note, there is also a class action lawsuit for this exact issue so I am confused as to why a recall would not have been issued, or why it would not still be covered despite the expired bumper to bumper warranty.

My car key keeps getting stuck in the ignition and won’t come out until we unhook the negative on the battery.

Repeat issues with the transmission, ongoing issue for about two months. Initially experienced the vehicle not shifting in drive or reverse, which was resolved in drive. The issue persists when in reverse, where I will put it in gear but it will rev without moving, as if the vehicle is in neutral . The dealership has replaced the valve body three times and is now awaiting other parts to attempt to resolve the issue.

Vehicle will not shift when needed or suddenly shift when it shouldn’t be, causing a lurching motion of the car. Then, the vehicle would not be able to be put into reverse. Appears to be a transmission issue.

I have noticed that when it's very cold, the vehicle will not shift to the two highest gears (I think) until 20+ minutes into my trip, and that's with having auto-started the vehicle 10 minutes prior to getting in it. So it takes about 30 minutes for the vehicle to shift into whatever the two highest (I think) gears are. This morning, 20+ minutes into my trip, I was going 71mph while pushing 4,000rpms, and it wouldn't shift. The temperature outside is 1 degree fahrenheit. The same thing was happening when it was cold in December. That day I don't think it got above 0 degrees fahrenheit.
