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!!

9/30/20 driving home and was accelerating to pass another vehicle, the tcs and stabilitrak lights came on and check engine light began to flash. A brief message popped up to service the tcs system and went away. Check engine light stopped flashing but tcs & stabilitrak/traction lights remained on. I stopped the vehicle as soon as I could, turned it off, waiting a few minutes and restarted - all lights had turned off. Problem has not replicated, but am scheduled for service (oil change) at dealer tasca Buick GMC sat Oct 3rd, will discuss during service appointment. (I commute daily round trip 120 miles) this is extremely worrisome)

Two incident warnings on my dashboard saying of my back hatch was open when it was not. Had it serviced because the dash warning would not shut off. Service said it was fixed then happened again. Twice this happened intermittently. Another incident when on navigation screen, when the Navigator gave directions it changed to phone screen and went back to navigation screen when she stopped talking, like she was calling me to verbally give me directions! the most worrisome was as I was going 50 mph on city street, my gas peddle stopped engaging with the engine and I was loosing speed, as I pressed on the gas peddle harder the car was decreasing in speed as I watched the speedometer. During that incident all was working including brakes, radio and steering. I proceeded to drift into a driveway to stop the car for help, good thing I was not on the freeway could have gotten killed. The car is getting serviced now, I do not want it back, will trade in for different make/model is this considered a lemon and which laws/action do I take? I've only had the car only 7 months when this started to happen.

Service bulletins pit 5663 and pic 6365A, GMC known problems before I signed my lease. Contacted GMC after penske Buick GMC, shillington pa, told me there was nothing they could do to fix the climate off error. Pushed an update through to fix the safety no alert sounds. At this point penske as well as GMC have no idea when the climate off errors will be fixed. I continue to pay my full lease rate for a vehicle that does not fully work.

When trying to start vehicle with push button ignition and brake pedal depressed, the vehicle failed to start. The dash lights would come on and error messages such as low battery came up on dash display. Vehicle was purchased on 11/17/18. Two separate occasions occurred where the car had to be jumped. One on 11/21/18 and 11/22/18. Unsure if an electrical wiring issue or battery issue?
