I’m crying out to you because I bought a 2019 GMC Terrain in April of this year with about 14,000 miles. The suv ran great for about 2 months and since then I’ve been dealing with nothing but a nightmare. We’re dealing with a situation where the suv goes into park while driving. We’ve brought the suv multiple times to GMC dealership and even reached out to GMC, and had no luck resolving the issue.

When I place the vehicle in reverse, my backup camera is not working, resulting in a blue screen with a message to have the camera serviced. Per the GMC dealership, this is a common problem with many of the newer GM vehicles and is a safety item due to not having a clear view of what is behind me. I purchased this safety feature and it not working.

The car failed to shift into gear. Message displayed, "transmission unable to shift" ,"2 gears selected " or "service transmission". Issued started in June 2022 while in drive thru line, when shifting from park to move the car would not shift. Had to turn car off for about 10 minutes and car was able to shift and drive normal. Check engine light came on about a week later and had checked for code p07b5. A couple of days later, light went back off. About 3 days later getting ready to leave home and car would not shift into gear again but turn car off and back on a couple of times and car shifted and drove normal. On July 13 2022 was driving in traffic and message displayed, unable to shift and service transmission. When I changed lanes and released the gas petal, the car went into park, stopped, and set the parking brakes, but did not turn off, jerking me forward and throwing things around in the car. Cars behind me had to slam on brakes to keep from hitting me because there was no initial brake light. I put on the flashers and turned the car off. Parking brake was stuck so I pressed it about 5 times before it finally released. I restarted the car 3 times and it finally shifted and drove as normal. I called gm to inquiry about a recall and was told there were none. I called for a diagnostic test and schedule is in about 2 weeks. The car has not been inspected by anyone listed above?⁸
