2014 GMC Terrain Complaint Log

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 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.

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.

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.

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.

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.

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.

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.

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.

There's an oil consumption issue that requires you to constantly refill the engine with oil between oil changes. It's so bad that it causes buildup and eventually interferes with the timing. Causing significant, unacceptable repairs! Now I'm forking out money for a constant issue that shouldn't exist! My car cut off in traffic! That's a major safety issue! I will provide costs of repair when I get the final estimate! My timing chain, tensioner and pistons may need to be replaced because of this issue!

All wheel light say it’s disabled

On December 26, 2022, my son and I were on our way to Indianapolis, Indiana from Anderson, Indiana. When we were about to the end of going through Ingalls, I noticed that my check engine light went off. I pulled over within 3 to 5 miles within notification of my engine light going off at a gas station. I turned off my Terrain, so my son could look under the hood to see if anything was amiss and I turned my Terrain back on hoping that the check engine light would go off. It didn't and the engine sounded normal. We proceeded to go on to Indianapolis driving on. Everything was fine until right before we reached 30th and German Church Rd. I started hearing what I thought was a clicking/ticking sound, so I turned off my radio to confirm it. As I turned down the radio to confirm the sound, my dashboard let me know that my engine was losing power and a stabilitrack warning. I immediately pulled over to check to see if my serpentine belt broke. It hadn't. My oil read at 29% and no other lights were on besides the check engine light. NOTHING letting me know that I was losing oil. A friend of mine came to listen to it and thought maybe my alternator was going out. I attempted to drive it to a garage that was maybe at most 2 miles away. It started right back up but lost power again less than a block away from where I stopped. I pulled it into a parking lot to get it off the street. I had it towed from the parking lot to a garage to have it looked at and I was shocked to find out that I was out of oil even though the dash read 29% before needing another oil change. NO OTHER WARNING that I was losing oil. The mechanic notified me to let me know that I had a blown engine. I'm furious with GMC right now because I had overheard approximately a couple months ago while getting my oil changed that GMC engines were going out left and right and now it's happened. to me. I don't even want to think about what could have happened to my son and I if on the interstate being very short notice

Car engine light coming on because of codes P0010, constant oil changes, acceleration slows. Turns off a low idle. No low oil warning lights at all.

I took the car in for a recall regarding the headlights. The recall number is N222363740. The dealer placed a sticker. On the headlights, which now makes it hard to see at night this is my wife’s commuter car to work at the hospital. We live in a very rural area where the 2 lane roads are remote and very dark.my wife works from 7:00 am to 7:30 pm but with her commute she leaves at 5;30 am and returns home around 9:00 pm . This includes every single shift she works, so the bottom line is she leaves at dark and gets home at dark, needing her headlights to work and home every trip. ever since they applied the sticker to the headlights, she’s having a much harder time seeing the road which is making it dangerous especially in winter weather. Since she travels by Two lane very dark back country roads. I am asking for a different remedy for the headlight situation, other than the stickers on the headlights that are actually making it harder to see. I’m afraid she’s going to get in a car accident rather it be with a vehicle or the many deer. We have run across the roads out here by not being able to see. I feel this is very time sensitive and would really appreciate a response back as soon as possible. Thank you very much.
