I bought my car in July of 2025 and since then my car keeps derating and reducing engine power while driving down the road at 70 miles an hour. It cuts out and decreases power. I took my car to the shop twice to have them tell it needed an update. I drove away and then the car does it again. Since December my car has down this decreased power, derated notice more than 30 times!! It is a safety risk for me and my family because you never know when it will happen on the interstate and when you will lose power. I have almost been rearended 3 times due to this issue and no one can seem to fix the issue.

Transmission dropped complete out of gear while driving. Got vehicle moving again. Took to dealership. Found complete internal transmission failure at 6779 miles. Transmission replaced with new unit. New transmission has erratic / hard shifts. Found replacement transmission leaking fluid due to front pump / porous case at 14800 miles. Customer Satisfaction Program N232433890 issued May 16, 2024

Feb 02, 2026

Powertrain System failure while driving, causing complete loss of power on road. The car lacks any accessible manual overrides to put in neutral or turn off parking break. This leaves the car stuck in park with all four wheels locked in the middle of the road in an incident with no safe way to move or tow the vehicle. When attempting to tow car must be dragged, and parking brake continuously engages. Tow attempt took nearly 3 hours to saddle the vehicle in the roadway. Vehicle currently awaiting formal inspection/repair from dealership.

I purchased a new 2024 GMC Terrain in March 2024. At the time of the incident the mileage was approximately 18,000 miles. On [XXX], as I was driving on a MA state highway, the car lost power with no warning. I was able to "coast" into a parking lot where I contacted OnStar; a flatbed tow truck was dispatched and the car was towed to the local dealership where it was purchased. At this time, the car is still at the dealer as I was informed by dealer service consultant that it's a "massive" transmission job and parts were on back order from GMC for over three weeks. I specifically purchased this vehicle to be safe on my monthly trips to NY to visit grandchild. I no longer feel safe in this vehicle and have no guarantee this won't happen again. The fact that the transmission failed in 1 yr. old car at 18,000 miles is of great concern to me. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

this just started on it's own. back up rear camera shows distortion from time to time and appears to be getting worse or happening more.

Apr 11, 2026

The rear camera is displaying the top of the license plate! It wasn’t doing it when I first purchased the car. Dealer states it is normal. I do not agree.

Sep 10, 2025

Vehicle shimmies upon acceleration from a stopped position.

Aug 06, 2025

infotainment system safety issues. I have video. Multiple times per week when starting the car and backing the rear camera engages. When placing car in drive the rear camera never shuts off, the sound volume doesn't work, the entire infotainment system completely malfunctions. The safety is when attempting to function the controls the volume will turn up and not able to turn it down, the screen flashes and the infotainment systems controls on the steering wheel do NOT function. I've had it to the dealer and they indicate PIC6591A from March 3rd 2025 is logged. When contacting GMC corporate they refuse to give any information. The PIC spans across many GMC vehicles including 2019 models. Why hasn't this been addressed? My son drives a 2024 Chevy Trax and this car has no issues like the my car does. His car also doesn't have the transmission/gear shift buttons like the 2024 terrain does. Anyone else having issues with the GMC infotainment systems, black screen, malfunction? I have video.

When shopping for a new Vehicle I noticed this but purchased the vehicle anyway. I attempted to look under the hood of my new GMC Terrain. I have a (hopefully temporary) handicap from a medical procedure I have been dealing with for over a year. I found that the hood assist springs or air shocks have been eliminated from the 2024 model. I can lift the hood on my 2010 GMC Sierra, but I had to have my wife help me lift the hood on my 2024 Terrain. My guesstimate is the hood weighs 50 plus pounds! Once the hood is lifted you have to install a rod (stick, like the old Model A and T cars) so the hood stays up. Yes, I am aware that Ford and Jeep have done this too, but that still doesn't make it right in my view. In this day and age of vehicle safety, and adding safety features to vehicles that I would never even have thought of, I can't believe this is OK! I can only imagine a mechanic bumping the hood rod, or a small child reaching up to boost themselves up to see what Dad or Mom is looking at or doing under the hood of the vehicle. This would cause a 50 plus pound hood to come crashing down on a person and that is OK? How about a short or elderly person? How much did the car manufacturers save by eliminating this feature at the consumers safety and cost? Maybe the manufacturers don't want us under the hood anymore, but then they will have to find a better way to add windshield washer fluid or check the oil or brake fluid.

AIR BAGS

2 complaints

The contact owned a 2024 GMC Terrain. The contact stated that while her daughter was driving 5 MPH on an intersection, another vehicle driving 40 MPH crashed into the driver's side of the vehicle, by the driver's side door.

The vehicle was deemed a total loss by the police officer. The vehicle was towed to a tow lot, pending assessment from the insurance company. The dealer and the manufacturer were not yet contacted.

ENGINE,FUEL/PROPULSION SYSTEM

2 complaints

Check engine light is coming on, indicating reduced engine power. Took vehicle to GMC dealer and they advised that the repair shop was getting assistance from the GMC Tech line to update a module to correct the issues. I was informed today that the high pressure fuel pump will have to be replaced, along with a hose or pipe to correct the issue. The vehicle has 57k miles on it. Upon researching the issue, I found that this has been a persistent issue with this model vehicle, dating back to 2020. It appears that it has not been resolved and the vehicles could stall or stop at any time. There is currently a class action lawsuit pending on this issue. Please help, this is dangerous

On Febuary 14 2026 I was driving on the feeder of the freeway with speeds of 50 mph my car suddenly down shifted in the middle of driving started shaking real bad stalled wouldn’t start wouldn’t go in gear at all would just die and say engine power reduced. This is after it had just been at the dealership and they said all I needed was an update. It had to be towed and the dealership said it was my high pressure fuel pump had failed. They replaced it and gave me the car back. I staled the next morning going to work on the freeway going 70 mph same exact thing happened except this time I could smell gas so strongly. I had to sit on the side of the highway until it was picked up due to gas smell and fear of fire. They say a bolt broke off of the high pressure fuel pump they just installed

POWER TRAIN,VEHICLE SPEED CONTROL

2 complaints

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.

Was driving along and transmission downshifted (?) wouldn't change gears. Tachometer was like a race car. Just went wild. Limped it along to a dealership. They informed us it was probably the transmission. It was determined it was indeed the transmission. They also stated that they had 7 more waiting in the service area waiting for parts to repair. Ours was to be #8. We called the dealer we bought it from, they sent a tow truck and towed it to their service area. Luckily, I wasn't out on the interstate going 70 mph as I would have been in just a few more minutes. Very scary situation as I was in 3 lanes of traffic. It was in town, so traffic wasn't moving fast. I was 2 hours into my vacation. Needless to say, that put a damper on things. Had to rent a vehicle, unpack my vehicle and repack the rental. Oh, and by the was it is a 2024 Terrain with ONLY 2400 miles!

FORWARD COLLISION AVOIDANCE

1 complaint

My wife and I took our new vehicle on a 7k mile road trip this summer. Two times while on the freeway around 70 MPH, the sensors went wild. The cars auto break came on and red lights and collision warnings went off in the seat and the HUD. The vehicle slowed down to about 35 immediately! Then everything turned off and we sped back went down the road like nothing happened. Luckily there was no behind us or in front of us for a good distance. The thing is during both of the there was a car in the lane next to us at our 1 or 2 o'clock position. Perhaps the sensors. Mistakingly thought we were about to hit that car. Can these seniors be adjusted?

a little over two weeks ago we were going to sidney to get groceries. it was hot that day so we turned the a/c on. fog started coming out of the vents, it looked like we turned on a fog machine! a few days later we were going to town, my daughter got in and the whole driver's side floor was full of water. there was so much of it we had to get the shop vac out to suck it up. I called the dealer where we purchased it from because it still under warranty. their shop guy was out for the week so they scheduled me an appt for the following week. by this time my speakers aren't working, my signal lights dont make any sounds when I use them and the floor is soaked again. on August 5th we took the car into high plains and left it. they said they worked on it for 4 hours and fixed the problem, some drain line was plugged with sludge and so the water knocked out a module or amp. I thot everything would be covered but then they said I'd have to pay because all of a sudden a mouse had causes that line to get plugged. I asked them for pictures because im turning it into my insurance company, and they said they would send them. they never have I requested the pictures 2x, once with Patrick the shop manager and then with Jeff presser, owner. Still today, nothing. Meanwhile yesterday here comes all the water on the floor again. We use this vehicle to haul my grandson to his therapies and medical appointments. he [XXX]. Now were worried that mold has started growing because even though were sucking up the water, the floor pad and carpet are still wet. I went online and have seen numerous people complaining about the same issue for years with these GMC Terrains, why hasnt there been a recall or national warning on this faulty problem?

Driving on slightly uphill 55 mph highway, vehicle started jumping & losing engine power. Engine light came on, I made it to the top as it was slowing down. Pulled off to the side. Put it in park for a minute. Message showing on dash read - acceleration power reduced. Drove it on home (engine light stayed on) parked it & had it towed to dealership the next morning. Got a call from dealership the same afternoon saying the vehicle was ready to be picked up. Picked up later in evening from dealership. They left keys & paper in car for pick up. We still tend the paper left it in the box showing we picked it up. The vehicle drove good back home. Drove it the next day, As I was pulling out from a stop sign, it started jumping again for a few seconds. Got home & had my husband to drive it, as we were coming up a small hill, it started jumping & losing power again engine light was blinking at this point. Dash board read engine power reduced. My husband kept on the accelerater & when we got on top of the hill engine light went off & we drove it back to the dealership & left it to be checked again. They kept the vehicle for 7 days & said they were not able to find concern. We picked it up again. Drove it back home without any incident. It has been parked since we got it home.

Vehicle was running but transmission was in PARK. Suddenly on screen in front of driver this message appeared: BRAKE SYSTEM FAILURE 43MPH TOP SPEED WARNING SERVICE ESC. Vehicle was not moving. Engine was running but vehicle was in PARK. I had to drive it home. Very difficult to stop. Brake pedal vibrated violently. Very long stopping distance even at 20MPH. I had the vehicle towed to the dealership from which I had purchased it. I bought this vehicle on 25 Nov 2024. Right now its mileage is 3757. Obviously my safety and that of others was put at risk. The service department at the dealership has not communicated with me at this time. There was NO prior warning nor were there any prior symptoms of this problem. It occurred VERY suddenly.

When accelerating, the engine revved up, switched itself from drive to park, resulting in complete loss of control and the vehicle coming to a sudden stop. The car behind narrowly avoided a rear-end collision by swerving around me. The malfunction indicator light came on for the first time, and the vehicle would not switch out of park. After turning the ignition off and on again, the vehicle would switch out of park. The GMC service inspector ran diagnostics and found fault codes related to the transmission valve components that must be replaced.

While driving, the dash warning "service power steering" light up and my steering wheel locked making me unable to steer or manuever the car to safety. I was stuck in the middle of the road.

Bought new car August 16th 2024. Few days later, I was turning left at a light and the car lost power as I was turning and error messages came up on the dash screen saying service transmission. I also observed that the cars gear indicator went to Park by itself even though the car was still moving. Pushed the engine start button and car came back on and I switched the gear to Drive. Took car in on the 19th to get looked at. Week later, driving down the city street going 40-45 MPH, car lost power again and car gear indicator switched to Park again, service transmission indicator came up and low fuel indicator came up even though I had over 1/2 a tank left. Took in to dealership on August 26th, 2024. Over this weekend, my wife was driving home from up north at a very busy freeway intersection and the car lost power again and luckily she was able to get over to the shoulder. It took some time but she was able to get the car restarted and made it home. There is something seriously wrong with this particular vehicle where we do not want to even drive it. This car has less than 500 miles on it and has lost power three times in three weeks.
