ENGINE
My husband just did an at home oil change on the car not long before the incident. Unfortunately my car was barely under 3,000 miles since the oil change and we were going to change the oil again when my engine died mid drive on the way home. There was no oil in the car due to high oil consumption and no coolant either. High oil consumption was not reported and not disclosed to me before and a broken guide for my timing chain leading to total engine failure just after I started to exit the highway. Had my car died any sooner I would have crashed. Or wrecked with another vehicle. GMC and the dealership I got the car from did not properly disclose this safety risk to me when I purchased the car and no recall information was ever sent out. The high oil consumption causing engine failure has been a part of a class action lawsuit for these vehicles before and THAT was not disclosed to me either at any point. No notifications of low oil or other issues aside from a check engine light came on for my vehicle when I was driving. I dont know how fast I was going as I was applying the brakes to my car for a traffic light.

ELECTRICAL SYSTEM, SERVICE BRAKES
ABS Brake problem and have tried to get it repaired for over 3 months and cannot seem to be able to get the part and call GM with no help. Can not tell me when or where to buy the part. Nobody seems to be able to get a new part and no help from GM. If there is this many problems that there is no part left available it should be a national recall.

FUEL/PROPULSION SYSTEM, ENGINE
I purchased this in March of 2025. 2 or 3 weeks after I bought this I took it to an oil lube shop and they said there was not any oil on the.dip stick. Also I started noticing the car being jerky while driving and when shutting it off it sputters. I took it to Max motors, a GMC dealer for a diagnostic check because it uses a quart of oil a week. They told me the high pressure fuel pump is bad and the piston rings were no good. This was on the 18th of June. I had taken it to the dealer I bought it from and complained about the problems, but he wouldn't do anything about it . The warranty was good at that time. Max motors told me it would cost me about $5000 to fix it which I don't have. I read that there was a recall on these cars with a 2.4L engine for these problems.

ENGINE
It has nothing to do with the headlights. I was told by a couple different technicians that there's an issue with there being a slow oil leak with the GMC Terrains causing the motor/engine to lock up. I get my oil changed religiously! I even have files/reports showing so. It was NOT time for an oil change and my motor locked up. I still have 3 years to pay on my vehicle and it's my primary ride. So after having it towed 4 times...I have to get it towed 1 more time back to the shop to get a used motor/engine installed for $6700 (that's what they estimated me). On top of not having a vehicle for 3 months and making payments on top of it.

ENGINE
On May 10, 2024 while driving my 2014 GMC Terrain driving at about 65mph my car cut off while driving to the point that the car started slowing down which had med confused as to what was going on but thankfully I was able to safely move over to the side of the of the highway in order to be in safer position to start the car back up. There was no warrant signs that the car had cut off but I had the air conditioning on do it stop blowing. At this point I knew the car was not safe to drive but I had to get off the highway. So I was about 5 miles from my exit which I was able to get to the exit without the car cutting off again on the highway but the car cut off once again on the exit as my speed was decelerating. I took my car to Meineke Car Care a few days later and was told that my car needed to have the solenoid replaced and the timing chain kit which was what the diagnostic was showing. Once they were able to fully inspect the car I was told that the timing chain kit was broken and I had medal in my oil which was suggested that I replace my engine. This put me at risk of being in an accident that could have injured myself or someone. There were no warning indications. My check engine light was not on. I had to pay to have the engine replaced which before I had it replaced I took my car to another shop just to get a second opinion in which I had the engine replaced.

I was driving my suv while it was raining heavily and my driver side wipers just stop working out of no where the passenger side still operates. I have not been to see if a dealer can fix it because I was unaware it was under recall so now I’m trying to find someone to fix it while under the recall.
