The Infotainment System started acting strange. The volume adjusts itself. It starts blaring very loudly and has nearly caused several collisions and it continuously turns on and off. I can not use it at all.

When I-€™m reverse screen shows blue and message says -€œservice rear camera system-€ I purchased this car NEW in 2019 and warranty just expired. I have read so many forums with this being a common problem with gmc. Why this isn-€™t covered and over $600 coming out of my pocket to fix it is ridiculous. This is a safety issue and gmc flaw and should be corrected/covered by them.

I was driving through a four way intersection with my children and the breaks locked up and I couldn-€™t get to a stop. This was the middle of September: There are MULTIPLE complaints on this happening with my model and someone is going to die if it-€™s not recalled. This is a serious safety concern. There was NO warning, or light to prepare me for the problem. Please do something to help us.

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?-¸

The contact's wife owns a 2019 GMC Terrain. The contact stated that upon making a left turn, the steering wheel would forcefully jerk to right, thrusting the vehicle into the opposite direction. The contact stated that the service ESC and service brake assist warning lights were illuminated. The warning lights would disappear soon after the failure as well as upon restart. The contact had taken the vehicle to the dealer on multiple occasions where he was repeatedly informed that unless the service light was illuminated upon arrival to the dealer, they would be unable to service the vehicle. The vehicle remained in the possession of the dealer and was not repaired. The manufacturer had yet to be notified of the failure. The failure mileage was unknown.

A couple weeks ago I got in my 2019 GMC Terrain and shifted into reverse and my back-up camera was not working. It was a blue screen that said "service rear vision system". a couple days later it started working again. My car sat for a wk and I got in it on May 28 to help my daughter move and it wasn't working again. This is a serious safety issue not only to me, but to anyone (like my grandkids) or anything behind my car as I'm backing up, especially if I cannot see them.

Found bulletin 19-NA-181 which was very close to all symptoms and stated to check for chaffed wires near the ECM. Found no spots in the tape where it was rubbed through but lost comms when wires were shook. Unwrapped main engine harness loom and inspected wires, found nothing. Started TAC Case # 9-6385087421 and was told it probably is a chaffed comms wire somewhere and gave me multiple locations to check. Found no damaged wires in those locations and shaking main harness no longer would make it fault. Put it all together and drove it down the road and faulted immediately. Unwrapped main harness again snd sprayed with saltwater to help conductivity but still couldn't get it to fault while shaking the harness. Only way it will fault is when shifting into drive the drive train bumps just right to bend the right wire. Checked every wire I could find and can't find the problem wire. Not drivable. When this vehicle faults it will not shift past 1st gear and sometimes locks out reverse. Must be towed. Needs the main wiring harness to start, recommend customer to authorize FSE to dealership CUST declined., all the lights and messages were coming on over the dash.

Bought the Terrain in Nov 22nd 2020 at covina Chevrolet, California. On Nov 25th wanted to restore the car stereo because the settings would not delete data saved and it wouldn't connect to my iphone via usb. So I decided to disconnect the posts from the battery terminals for 30 minutes. Connect back the posts to battery and check if that delete everything and it did but it still wouldn't connect to my iphone. That's when I noticed that SRS and service ESC message came on. The ABS, airbags and stability lights were on, turn off the vehicle and turn it back on and didn't fix the issue. I made a repair schedule where I bought the vehicle and till this day Dec 13th they haven't fixed the issue or their not even trying. Service advisor advise me that they are getting in touch with a field GM engineer that was a week ago. I'm thinking its just the computer that is frozen a malfunction ABS module controller or a fuses or a relays because I drove the vehicle to the dealer and had no issue. I live in oxnard, California and its about 1hr 30min from the dealer. I'm still hoping that they can fix the issue because I really like this vehicle. Please help GM!!
