Shift to Park comes on after vehicle is shifted into park and the vehicle is turned off. You have to hit the gear shift or jiggle it to register it is in park or start the vehicle and shift to neutral and back to park and turn it off a few times to get it to register it is in park.

When putting the vehicle in park I receive a messege saying "shift to park" this means the vehicle is not recognizing I put the vehicle in park. This is a safety issue my truck is not even off when this message pops up. GMc knows about this issue and their is not a recall on it. Dealer will not fix the issue becazue it actually has to say that messege when they are diagnosing the problem. It does it randomly but more frequent now. I call gmc the only thing they can tell me is record it when it does it as a paper trail I guess. They are saying the same thing the dealership is saying they can't diagnose the problem without the shift to park messege. Been having this problem when I hit 20,000 miles

I was waiting at the traffic light and the car just shut off without any warning and it wouldn't start back up. After a few minutes a warning came on that said "battery low-start vehicle." When I tried to start the vehicle it still wouldn't start. Then all of the warnings lights were flashing on the dashboard the wipers were moving back and forth but the vehicle still wouldn't start then the car just shut down and and nothing would come on. This happened in the lane of traffic at the red light. With the hazard lights not working it was a dangerous situation. The police were called to be there with me until the tow truck came so no one would run into the vehicle. I feel that the fact that no warning light flashed before the car just shut off was very dangerous especially after it wouldn't start back up. I had just purchased this vehicle (used) December 2022. I am very frustrated because now I don't have a vehicle to get to work. I only purchased this vehicle because my KIA was stolen and totaled October 2022 and I needed transportation to get to work. The car is at a Chevy Dealership now so they can try to figure what's wrong with the vehicle.

When I shift the gear from PARK to DRIVE & step on the GAS, the vehicle hesitates to DRIVE. I have to turn off my vehicle, play with the gear shift, then shift again to get it to move. The other day I put my vehicle in DRIVE and it rolled back and REVERSED. Nobody can figure out what-??s wrong with my vehicle. The check engine light comes on then goes off. Nobody can get the problem to duplicate. A ticket to GMC was submitted and from them, my vehicle seems fine on paper. This is a safety hazard. I-??ve taken my vehicle to a Chevy dealer and also to a GMC dealer multiple times.

Started having issues where all the electronics on the car go blank/dead. So far when this has happened it has not caused the car to be inoperable but in the meantime I have found that the car is leaking (seriously leaking) under the entire drivers seat was soaked. I noticed a while back that it smelled like mildew in the car, I had it cleaned and put a damp rid pouch in there, that basically absorbed in 2 days, but never could find the water. This week I found the water...under the drivers seat. This car has been leaking for 2 years! Last night, I get in the car and plug in my phone to charge and get a message of LIQUID DETECTED Charging is not available because liquid has been detected in the lightning connector. Disconnect to allow the connector to dry. At the same time the phone was plugged in everything started to crackle and squeal through the radio and then no radio at all. There is no way all these components are not damaged. Meanwhile I have take it to a dealer for them to do a "water test", I have zero confidence that this water test will yield any positive results and I am without a vehicle. So I am trying to get this info out anywhere I can to see if other people had similar issues and what can be done. It can not be safe to drive a car that the electronics have water damage.

Cutter Chevrolet in Honolulu had a recall on my vehicle for a jack unable to support the vehicle. I had the appointment to address the recall. Their solution was to remove the jack without a replacement. Now I no longer have a jack. It will now cost me to have someone else to change a wheel that I can do myself. I have a spare tire with no jack in my new vehicle

Two times I have heard a loud pop noise coming through my stereo speakers. I noticed it when applying the brakes. I went on a Trailblazer forum and a few others had reported the same thing. I heard the pop today when I was pulling into a parking spot and applying the brakes.
