Driving 75-80mph in the freeway when suddenly the power stopped in the middle of the road and couldn’t get it to run. Thankfully freeway exit was near was able to get the vehicle to safety. Tried to turn in on again and would turn on but die down after. Had to tow the vehicle and take it to the dealership the next day. Said it was fuel pump module defect and there’s nothing I could have done to cause it. Vehicle is less than 3 years old with good maintenance

POWER TRAIN, SUSPENSION
First time I had problems with my 2021 Terrain I took it to victory GMC on 9/20/24. At the it had 45,000 miles. Every time I would drive and accelerate it would shake extremely bad in the floorboard. There was also transmission fluid leaking. I picked the car up on 9/27/2024 and was advised that both front axles were replaced, which corrected the shaking and the driver side axle seal was replaced, which was where the leak was coming from. this was covered under warranty but at 45,000 miles I should not have been already having axle problems or any type of leak. I dropped my car off again on May 5, 2025. When I called them the day I made the appointment I let them know I had a service transmission message show up and then go away, I told them it’s taking longer to kick into gear when I’m on the highway, I told them it revs up past 4 1/2 RPMS at times when it had not previously done this and it just sounded like the engine is working harder. I also told them I had a check engine line come on and go off and it was code P2271 which was an oxygen sensor code. I also told them when I had the oil changed. They told me there was a slight oil cooler leak starting. All this was supposedly addressed when I dropped it off to be serviced on 5/5/25. I was called on five 625 to pick up my vehicle notifying me that they found no issues. They were unable to verify concern concerning my check engine light. They said there was no oil cooler leaking, it was just slightly seeping, so not considered a leak. And they said no transmission concern operated as designed. Fast forward to May 9, 2025… I got in my car in the morning and once again the check engine light was on. I drove it straight to GMC and had them put the reader on it. The oxygen sensor code came on. The same code I told them about on the 5th that they said was fine on the 6th. I made an appointment once again to get this check engine light looked at although the check engine light is not on at the moment again.

POWER TRAIN, VEHICLE SPEED CONTROL
Unintended acceleration in forward and reverse: the vehicle experiences unintended acceleration both in forward and reverse. While driving in heavy traffic, the vehicle continues to maintain throttle position for approximately two seconds after releasing the throttle, creating a dangerous situation where the vehicle continues to accelerate towards other cars. This defect requires emergency braking to prevent a collision. In reverse , the vehicle also holds throttle position after the accelerator is released. This results in the vehicle unintentionally accelerating in reverse at a rapid pace. This requires the driver to depress the brake moderately to control the reverse speed. During this event the driver is fighting against the motor with the brake pedal until the vehicle decided to stop accelerating on its own.

Drive shaft on my GMC Terrain needs to be repaired according to my repair shop. I brought it in as it was vibrating on acceleration and other times frequently. I was told it was the “drive shaft” and the mechanic states they have had Equinox and GMC Terrains coming in for same issue. (Specifically my year Terrain) I looked up and found this recall # for this issue: N212343560. I was never notified and now have a very expensive repair bill which may or may not fix the issue.

FUEL/PROPULSION SYSTEM
Three times in one month, four months after purchasing vehicle from dealership, the vehicle stalls while driving and will not restart. After running codes, each instance prompted a P129F code for the fuel pump driver control module. After the second incident, the vehicle was inspected by a qualified repair shop and no issue or stored codes were found. When the issues occur and the car stalls, the Check Engine Light and a Low Battery warning message can be seen on the instrument panel. When this issue occurs, the vehicle's gears cannot be shifted manually. The vehicle must be force shifted by hand, via transmission components under the hood, in order to place the car into neutral.
