My GMC terrian has 98567 miles and had check engine light problem. Dealer said that I needed new timing chain. Cost $2282.05. Have not found a recall on the timing chain problem, but have seen many complains about the same issue. With some being replaced multiple times. Why has GMC not done anything to cure this problem. Van does not burn oil. Have it serviced at the GMC dealer since I purchased it with only 16000 miles.

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.

The timing chain is failing on my 2012 GMC Terrain. It’s dangerous to drive and it started without warning (to me). It’s my understanding that this is a common problem with this year and model GMC vehicle as many owners are complaining about the same issue. Will GMC be notified so they can remedy this situation? Many thanks.

My vehicle keeps running extremely low in oil and not alerting me with any warning lights. My vehicle starts to shake like it is going to stall and the engine makes a rattling noise. This is a safety concern.

Engine lost power suddenly while driving. No warning. Fuel pressure slowed to where vehicle no longer moved forward. Again. No warning. Timing chain slipped TWICE and destroyed engine without warning. “Engine power lost” appeared on dash from driving without warning or incident. Excessive oil consumption without warning. Smoking engine even though had regular oil changes. Engine had been inspected by dealership and allegedly had no issues. Car never smoked but did after second time of timing chain slipping/breaking. This issue has happened repeatedly to many drivers who own these vehicles. Had a difficult time stopping after engine and total power failure without warning.

Not really sure if it is electrical but the Stabilitrak light came on and the car jerked and I could not go over 50 mph and that would be fine however when you are on a freeway and the speed limit is much greater you could cause and accident. I took the vehicle to a garage and they put it on there computer and reset it and it seemed to work OK until I again went on the freeway and the same thing happened. Again I took it back to the same garage and they recommended I take it to a GMC Dealer which I did and they could not find the problem either after spending around $600.00. I did take it to the GMC Dealer which the vehicle make is a GMC.The problem, to the best of my knowledge, started about April 2023.

The engine cutoff while driving through a major intersection in 3/2022 with no warning lamps, messages or other symptoms of the problem prior to the failure. Dealership replaced the fuel pump module. Subsequently, the engine cutoff while driving in 5/2023. Dealership replaced the fuel pump module. Each of these occurrences placed my life, my passengers life and the lives of others on the road in danger as an accident could have resulted if I was not able to coast out of harms way. GMC has an existing recall on the fuel pump module for 2021 - 2022 Chevrolet Equinox and 2022 GMC Terrain vehicles. Why did this happen a second time after replacing the fuel pump module? Are they using a module included in the recall? I was charged $ 591 dollars for the repair in 3/2022 and no charge in 5/2023 as they stated it must have been a faulty module. I have no confidence in my safety and the module they used in 5/2023 is not faulty.

Multiple brake lines have corroded out of the gas tank. This caused gas to slowly leak from the vehicle . Not available for inspection - currently being fixed. Dealer confirmed multiple lines corroding. It has been inspected by a certified dealer, Golling in Chelsea, Michigan. There was no warning. Initially smelled gas, but could not pinpoint where it was coming from. Eventually the leak became so large that gas usage was excessive and smell was very strong.

I was on the interstate, heading out of town. I heard a loud noise from under the car. The car started slowing down and would not accelerate. This could have been very dangerous if I had been in the middle of 5:00 traffic. I took the next exit in front of me and pulled into a gas station. Looked under car and seen no obvious damage. Got back in and the car and put it back into drive. It would barely pull and then quick pulling all together within a few feet. The D/drive light started flashing. No warnings at all before this happened. I was 200 miles away and had to have it towed back home. Put it in the GMC shop and was told it needed a transmission.

In mid traffic my 2018 GMC terrain just stopped with no warning, no check engine lights, no smoke from the vehicle, nothing. I was in Charlotte traffic, driving, with my family in the vehicle, the car stopped right in the middle of driving, and I had to quickly and sharply turn the wheel to got into a median to avoid hitting the car in front of me and avoid being rear-ended. The dealership informed me that the vacuum pump in the engine cracked (broke) causing another part in the engine to malfunction. There were no, none, warning lamps, messages, or other symptoms prior to this incident that would of indicated a problem so that I can proactively service the vehicle and keep my family safe.

The infotainment center has a tendency to freeze upon starting the car. Subsequently, when the car is put in reverse the back up camera will remain on for several minutes after putting the car back into drive causing a distraction to the driver. The freezing of the infotainment screen will often stay frozen even after turning the car off. When the car is off and the door is closed and locked, the screen stays on and music stays blasting, unable to turn the music down or off even though the car is off and locked with no one inside. The screen has stayed on for over an hour and upon returning to the vehicle, the car took several tries to start. I can only assume that the freezing is beginning to cause the battery to drain. This is causing a safety concern as loud blaring music is distracting and the possibility of being stranded without being able to start my car is a scary thought. This problem has been occurring since I purchased the car and has not been able to be reproduced by the dealer as it only happens randomly a few times a month.

I was driving down The expressway. The traffic in front of me came to a stop. When I went to apply the brakes I had no breaks. The pedal was as hard as A rock So when I realized I couldn't stop I swerved over into the breakdown lane. And continue to pass cars at a high rate of speed until I got the car to stop. There were no check engine lights on Then I had the car towed to the Dealership Where they tell me is a break vacuum pump. That has damaged The Cam shaft. Pistons and rods in the engine. Totaling $7200. In damage. No one seems to care and I still owe 20000 on the car. Car has 71000 miles on it.

Bought my 2013 GMC Terrain SLT in 2017 from Carvana. I did not know there had been low oil issues or catalytic convertor issues that GM had put out a letter to get replaced in 2020. I always had to put oil in it. It just burnt right out. I also replaced 3 catalytic convertors. Fast forward to now 2023, I'm driving and my engine starts knocking loud. It has oil in it at this point. It finally died half way home 52 miles out. I had it towed home and then to a dealer. I find out from them that there was metal intermix with the oil and that this had a warranty for this issue. But... now my vehicle is 10 years old and over 120,000 miles. Now I can't get the warranty because it expired. that's crap! This should be a recall by now considering this has happened to numerous people with this year make and model. I can't spend $9,698.00 on a new engine.

The engine burns oils twice as fast as it should and gives no warning of a problem. I am 3 years into payments on this vehicle and the engine is shot due to this issue. I have under 80,000 miles but this is a major problem that GMC is not addressing its very frustrating I will have to pay off a damage car they sold and now buy a new for an obvious problem they won’t acknowledge
