ENGINE, UNKNOWN OR OTHER
Broken rear main seal broke which causes oil leak. Almost all GM vehicles around my year have the same issue resulting in blow engine. $2000 to repair and GM told me they know of this being an issue but won’t do anything to resolve.

While driving my vehicle, check engine light came on. Then, my car proceeded to flash about 4 warnings on the dash, Fuel Level Low (had half tank of gas), Engine Power Reduced, Service ESC, and Service Transmission. My vehicle shut itself off while driving 55 down a main highway and put itself into park. Forcing me to pull over and be stranded on the side of the road. In the way of other cars, with no way to get out of the way. I then had to shut car off, wait, and start it back it up. However, after the first time this happened, I cannot drive my vehicle more than 15 to 20 minutes without it doing this to me over and over again. To make matters worse, I am 37 weeks pregnant, and the last thing I need is to be without a car. I also had just gotten my vehicle inspected and an oil change the week before, with no issues to show. The only thing I did to my car before it did this, was remote start my vehicle, which I do every single morning and have for the little over a year I've owned this car. Also, my car has less than 60,000 miles on it!! The mechanic who is currently working on fixing this issue for me, has concluded it to be a throttle body, or the actuator of the car.

AIR BAGS
The OBD airbag deployment sensor is displayed. The GM dealership service center advised the airbag may not deploy in the event of an accident. The service center advised that we would need to pay for the airbag and sensor to be replaced / repaired regardless of the ACRO agreement to replace and repair airbags. This is unacceptable and a danger to all drivers or passengers of the vehicle. It appears several other complaints have been filed where drivers or passengers were injured due to this issue.

POWER TRAIN
I have a 2014 GMC Terrain with less than 70k miles on the vehicle. I took the truck to the mechanic and was advised the power belts were no good. Why is this? The truck has no mileage on it basically for a 2014, I have a 2011 Chevy with more miles than this truck and its power belts are fine. The Mechanic also advised me within the last 3 years, his shop in Cecil County MD has changed over 125 Power Belts on the 2014 GMC Terrain AWD (V6), same vehicle that I have.

ENGINE
The rear main seal for the engine fails because of a clogged PCV valve. This was a problem on previous years for the Terrain and other vehicles that carried a similar type of engine. There was a recall for those previous years (2011-2014). My vehicle is a 2015 GMC Terrain, and I am currently experiencing the same issue. I took my vehicle to a licensed dealership and they quoted me a price of close to $3,000 to make the necessary repairs. In my opinion, since the same issue/problem is occurring, there should be a recall issued to include at least the 2015 year models for that engine.

STEERING
I was driving the vehicle, approaching an intersection and making a right turn. As I turned the steering wheel, it locked. I kept trying to turn the steering wheel and it finally did. A Service ESC error appeared on the dashboard. The T/C light came on as well. I drove it home. The error was gone the next time I started the vehicle. The service code kept coming on intermittently. Appointment scheduled on 11/10/23. GMC service dept stated they wouldn't be checking the vehicle until next Monday, so I could take it home. I rescheduled and took it back on 11/13/23. My vehicle was there for 32 days. My safety was at risk because of the failure of the steering wheel to turn, with traffic in the lane next to me as I was turning.The service dept was able to download the error codes.Code C0800 was captured. The steering gear assembly was removed and replaced, programmed and calibrated.

STEERING
2nd incident, 1st incident reported: Complaint number 11570916. Was driving the vehicle and the steering wheel locked again as I was making a right turn. The service ESC light immediately came on with the T/C light on the dashboard as well. I had roadside assistance pick up the vehicle to take it to the service department because I was afraid to drive the vehicle. According to the service invoice, they were not able to replicate the problem, but I have a photo of the error code on the dashboard. I was told that they checked the brake module and reprogrammed the computers.

In September of 2022 my gmc automatically shut off right in the middle of traffic on a Friday night. No warring, no lights to indicate that something was wrong with my vehicle. I took it to a mechanic shop and they said nothing was wrong and they did a diagnostic test on the car and no codes popped up. A week later my engine light came on. And my car died again. Thankfully, I had an extended warranty on my car and took to another mechanic shop. It turns out the timing changes on my car needed to be replaced. Fast forward to today Jan 22,2024. I smelled burning oil every time I would drive the vehicle. The rear main seal and PCV was leaking in between my engine and transmission. I lost 5 quarts of oil between Wednesday and Sunday. My oil light never came in. Thankfully, my engine didn’t lock up. It is currently in the shop getting repaired. My car is still under an extended warranty.

AIR BAGS, ENGINE
The air bags will show that they are shut off while we are driving down the road with my wife sitting in the seat and they will also does it if we are just sitting in the drive way. Also they had a recall in the older models of this car for the pvc valve getting clogged and building pressure and causing the lower seal to bust and that happed to my car but they never gave a low oil light when it happed. All that happed was my wife was driving and the lower engine power came on while she was driving in traffic causing her to freak out and feel unsafe with my kids in the car as well. I contacted them about and they said there is no recall for the car at all about it. They clearly still had the same issues in my car because the pvc valve was clogged and then now I’m loosing all of the oil from my motor. When I went to out oil in it after work I had to add 4.5 quarts of oil to it and it only holds 5 quarts. It still never had a low oil light when I went to start it to get it to level ground so I could check it. Clearly this is a safety issue and I don’t want it to happen to someone while they are on the Interstate during heavy traffic and potentially cause an accident.

While turning from out of. Wheel gas station, the truck just stopped abruptly and shut off. It left me in a turning lane that curves to a stop at a stop light. I was in a dangerous spot. It was raining and dark. The Burr Ridge police had to come due to the position my truck was in and push me out of the lane and danger. I had it towed by AAA that night. Then had to have it towed to a mechanic. Who informed me that it was the timing chain belt.

SERVICE BRAKES
Brake booster failed with no warning. Brake pad was hard to push down as I exited the freeway. I came close to hitting the vehicle in front of me which would have resulted in a bad car accident. There were no warning. This is extremely dangerous and is a risk to not only the driver but also to vehicles in the path of a vehicle that cannot stop. This needs to be a recall along with the other vehicles that have a recall for this part.

ENGINE
I was driving our 2017 GMC Terrain in subzero temperatures when my vehicle started making sounds and loosing power. With in seconds I heard a pop, and then my dash went crazy with alarms. I had it towed to my local mechanic who determined that the vehicle's engine was seized do to a frozen PCV valve that caused the engines real seal to give away. If need be, the the vehicle is currently available to be examined. My family's safety was in danger because of the location and frigid temperatures that were present at the time of the breakage. The vehicle has not been examine by a GMC dealer, just an independent mechanic. There was no warning what so ever of a possible problem. The vehicle started making sounds and loosing power. With in seconds, I heard a pop and all the lights on the dash light up. We had no other issues with this vehicle leading up to the breakage.
