Common Problems with the 2021 GMC Terrain
Powertrain, Transmission Issues:
“The contact owns 2021 GMC Terrain. The contact stated upon starting the vehicle and attempting to shift the vehicle to drive, the vehicle inadvertently reversed. The contact depressed the brake pedal. There were no warning lights illuminated. The contact stated that the gear shift selector was stuck in park(P) position while the instrument panel was displaying that the vehicle was in neutral. The vehicle was towed to the dealer who informed the contact that they could not replicate the failure; however, the vehicle remained under observation at the dealer. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure but did not provide any assistance. The failure mileage was unknown. The VIN was not available.”
“My 2021 gmc terrain with 6000 miles on odometer. When driving up hill or going around corner transmission shudders so bad that it feels like front tires are coming off. I contacted the dealer and gm and was told there is a tsb for this complaint. GM and dealer acknowledged there was a problem but they didn't have a fix or known cause of problem”
“When driving car starting from a red light/getting on freeway or after making turn from a stop light when accelerating between 45 and 60 car shakes when shifting. Problem is getting worse. Car only has 6000 miles on it. I reported it to local gmc dealer and I was told GM is aware of the problem and they do not have a solution. They mentioned there is a TB out for several models that customers have reported same problem”
Electrical Problems:
“Just purchased this vehicle has about 64500 miles on it. When accelerating between 40-55 (hard acceleration) my vehicle wobbles really bad, seems like a tire issue. Have had the front end looked at, and tires all balanced and inspected. Noting out of the ordinary. Then all of a sudden my rear view back up camera works, but my back up assist symbols are not showing/working. I checked the settings and they are turned on. To top off the cake, when the weather is cold outside my windshield wiper fluid will not spray from the front windshield or rear, then when it warms up or is parked in a garage it works again. I have made sure the correct wiper fluid is added as well so it does not freeze. But apparently it is getting stuck somewhere......”
“While driving my vehicle and talking on the phone, the radio screen went black. Bluetooth or nothing in connection to it was working. After about 2 hours it came back on. I was told to bring to dealership to be checkout, but it came back on. I'm going to take it to the dealership. My vehicle has 13,000 miles on it.”
“I dropped my son off at school and he mistakenly took my car keys into school with him, and somehow I was able to drive all the way home, 4.5 miles, with no key in the car and no warning to stating the remote wasn't in the car. The issue with this is if I'd driven further, perhaps to another state, or even driven somewhere at night, I would have been stranded once I turned the car off. There was no indication that the remote wasn't in the car, and the car never cut off. I only knew the remote was gone once I arrived home and turned off the ignition. That's when the message displayed that the remote wasn't in the car. I had to call an Uber to go back to my son's school to get the key. This could have been a disaster had I driven further or not had the funds to get back to my son's school. Not to mention if a car thief had someone occupied my car and driven off in it. They could have gotten as far as they wanted (or gas would allow) before the car shut-off as long as they didn't turn off the car. I stopped at stop lights and stop signs and the car just kept going. The issue should be looked into and addressed immediately. This just occurred yesterday. The vehicle has not been inspected and this was the first time anything like that has happened. I normally receive a warning message if my remote isn't in the car even if it's just in the house. This is clearly a defect that needs to be fixed.”
Brakes Problems:
“Recently I have noticed that the back brakes squeak and sound like they are grinding when backing up. Also every now and then the information screen will go black for a while then turn back on could be a few seconds or several minutes. 23,900 on car”
“I was going to my sons home which is located on a steep downhill street with several turns, one of their almost 90 degrees. As I started to descend the hill and gain speed, I depressed the foot brake. It did not respond at all. As I continued to gain speed and coming up on the sharp curve, I continued to pump and apply brake. The brakes did not work. I continued to gain speed and go around 2 other turns. At the end of the street I had a choice to continue straight ahead and hit a house, turn right and continue down another steep street until I hit a home at the end of the street or try to turn left and go up hill. I turn left up the hill and finally got stopped before I could put the vehicle in park or apply the brake I began to roll backwards on the steep incline . I rolled by and hit a curb, jumped into the yard and hit a bush,small tree and an electric ground transformer, coming to reset about 4 feet of the ground on top of the transformer.. The utility workers said that I was lucky not to get electrocuted. This vehicle was purchased about 7 day prior to the accident, the brakes simply failed and did not work at all”
