2014 GMC TERRAIN Recalls, Complaints & Safety

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.

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.

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.

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.

Vehicle is consuming excessive amount of oil in short drive time up to 3qt in less than 1000 miles. With no oil leaks. Vehicle only has 139840 miles. Has regular oil changes and services done.

My motor blew out of nowhere. I took it to a shop and there was no explanation as to why. I barely drive my car and keep up with oil changes. Please help asap!

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.

Was driving from home to my job in Novi, MI. While driving at 70 mph on [XXX] [XXX] miles west of Grand Rapids the motor suddenly stopped. There was never any warnings on dashboard instruments, no audio signs, and no physical signs this was about to happen. Had 16% remaining oil life before next oil change per computer. Dealership is telling me there is no oil in motor and it has suffered a catastrophic motor failure after timing jumped. This almost caused a major accident at highway speeds. Motor only has just over 77,000 miles on it. Of course it is out of warranty. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.

While driving oil blew out of engine of 2.4 eco tech. Single digit temperatures. Very little warning caused engine to lock up cost over 5,000 to replace engine.

Vehicle started leaking oil with no indicator. Didn't realize it for at least a few days. When I smelled a burned oil smell took it to the repair shop. Was told my oil gasket blew and the engine is about shot. I also only a month earlier replaced the battery. These vehicles apparently have known battery, oil and engine issues that were known since 2010. The following class action lawsuit in Missouri is pending: [XXX] , on behalf of herself and all others similarly situated, Plaintiff, v. GENERAL MOTORS LLC, Defendant. _____________________________________ Our vehicle is not even at 100,000 miles! This will cost thousands of dollars to fix or we will need to purchase a new vehicle which we didn't plan on for a few years at least! This has been devastating. Please help.

2 and a 1/2 months after I bought my 2014 GMC Terrain used. It had no oil in it. I had to put pretty much a whole new engine in that cost me $5000

On October 13, 2023, I was driving on the highway when my 2014 GMC Terrain power was reduced. Suddenly, the engine light came on and car began throttling. Second, an error message appeared on my dashboard indicating “ engine power is reduced.” Then it stopped in the middle of the highway. I was able to restart my vehicle and drove it to a nearby mechanic shop. The mechanic said the problem was my timing chain and that my vehicle was not drivable. I left my vehicle at the mechanic shop because it was the weekend and It needed it to be towed to the dealership. On Monday, October 16, 2023, I had my vehicle towed to Buick Classic Service Center. After waiting for two days, I received a call from the service center stating that my 2014 GMC Terrain timing chain and pressure gas pump was the cause of the problem - with my vehicle. After, reading other owners similar complaints ; why is there not a recall to address this problem? Now, I am stuck without a vehicle and the company has no idea how long it will take to get the parts needed to fix my vehicle. I was told that the timing chain and a tension is on back order due to the employees of GMC being are on strike.

I haven’t had a call back from the dealership it has been over a year since I’ve heard anything from them to get the recall fixed.

Crash 2 injured

Vehicle shut down and turned off while being operated. No warning lights were on at any point before the incident. I was driving down the road and without warning, it just turned off. My safety as well as the safety of the drivers on the road around me were compromised by this sudden failure as the vehicle was in motion when the incident occurred and I was unable to properly operate the vehicle. When I tried to re-start the vehicle the engine would not turn over and several warning lights were suddenly on. Vehicle was towed to dealership and the service department said the timing chain jumped and the engine needs to be replaced. Multiple complaints have been made against GM for the faulty 2.4L Ecoboost Engine that causes excessive oil consumption with no appropriate monitoring or warning system in place leading to timing chain issues/failure that destroys the engine without warning, often while the vehicle is being operated. No recall has been made and no warning is given to customers who purchase vehicles with these engines. I have owned this vehicle less than a year and the repair invoice I was given quotes over $10,000.
