general problems of the 2014 GMC Terrain - part 1

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 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.

The contact owns a 2014 GMC Terrain. The contact stated that the was consuming an excessive amount of engine oil; however, there were no oil leaks evident. There were no warning lights illuminated. The vehicle was taken to a certified mechanic who informed the contact that the frame near the rear wheel on the driver's side was completely rusted. The mechanic stated that the vehicle was not safe to drive. The vehicle was not diagnosed for the oil consumption failure. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 71,000.

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.

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 I-94 24 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.

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.

The contact owns a 2014 GMC Terrain. The contact stated that while driving at various speeds, the vehicle was consuming an excessive amount of engine oil. There was no warning light illuminated.

The manufacturer was not notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 50,000.

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: rachel buchholz, 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. Lindsay popovich.

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!.

See attached document for complaint.

The contact was advised by the mechanic that the engine needed to be replaced. The vehicle was not repaired. The contact stated that prior to the engine failure the contact was continuously adding oil to the engine. The contact was adding one quart of oil every week for more than 10 months. The manufacturer was informed of the failure. The failure mileage was approximately 150,000.

Oil consumption issue caused timing chain to go causing catastrophic damage to the engine resulting in over 3000$ in repairs the oil light does not come on nor does it have a low oil pressure warning.

Pcv system plugged up pressure in engine when remove oil cap have cleaned it my self.

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!.

Other years of this vehicle have recalls for the catalytic converter. My check engine came on and it said it could be that or the O2 sensors. O2 sensors have been replaced and the check engine light is back on.

Timing chain malfunction that burned through oil causing the engine to seize. No engine light indicators were displayed in regards to this issue. The issue escalated quickly with signs showing only 2 days before the engine finally seized & leaking oil into engine bay. It is also noted that the engine oil has had many reported leaks into fuel tanks & other areas of the car.

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.

The contact owns a 2014 GMC Terrain. The contact stated that while driving at an undisclosed speed, the engine seized and then the vehicle lost motive power. No warning light was illuminated. The contact stated that the vehicle previously had an oil change, but the engine consumed an excessive amount of oil. The vehicle was towed to the residence but had not yet been diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 109,000.

My engine burns a very large amount of oil rapidly. I have to replace oil in the engine at least twice a week. I went to the automotive service center and they indicated that my timing chain need to be readjusted and that the engine itself between the year of 2010 and 2017 on GMC Terrains have major problems/ defects in with the engine. I was driving on the highway and the car slowed down I barely could get any acceleration. I then had to get off of the expressway to avoid collisions. I took my car to the shop several other times for automatic brake system problems and stability track problems. I had censors replacedvand stability track problens. They wrre fixed but the automotive technicians indicated they the oroblems will happen again. Soon after that my engine was low of oil again within the matter of two or three days. The problem (massive oil consumption) continues to happen. I have investigated the problem and I found that there were engine class action lawsuit on the GMC 2014 Terrain because of the engine problems. I need to know how I can get my problems with the engine in particular resolved so that I can move forward and not worry about being involved in a motor vehicle accident when I drive to work each day.

Issue of timing chain failure. After 100,000 miles of use during which time no engine warning lights of any kind were observed the timing chain broke disabling the vehicle & resulting in dealer repair estimates upwards of $10,000.

My car had been needing at least 2quarts of oil in between oil changes which I have done every 3000 miles. The timing chain is bad which is caused by excessive oil consumption. The service power steering and stability track light comes on it its messing with the transmission until I disconnect the battery and reset it, and it also leaked inside my glove an f the passenger floorboards.
