2014 GMC Terrain engine problems

“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.”

“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.”

“The contact owns a 2014 GMC Terrain. The contact stated that while driving 50 MPH, the vehicle started jerking and hesitating abnormally. A dealer was contacted. The vehicle was towed to a dealer, where it was diagnosed and determined that the piston rings were damaged, the high-pressure fuel pump had failed, and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 130,000.”

“The contact owns a 2014 GMC Terrain. The contact stated while driving at an undisclosed speed, the contact became aware of an abnormal odor coming from the engine compartment, with the check engine warning light illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed that the engine failed due to excessive oil consumption. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The dealer was not contacted. The manufacturer was made aware of the failure. The approximate failure mileage was 125,000.”

“Tensioner issues keeps breaking the timing chain. . Replaced twice at own cost. Fuel pump/ loss of power while driving. Back up camera doesn't work sometimes. Screen goes black. If key is left in the ignition it starts itself. If you try to use a car charger for a phone the AC shuts off and a "systems error" message pops up. This happens alot. It's an ongoing issue since I bought the car in Feburary this year.”
