2014 GMC Terrain: engine failure

Filed Feb 18, 2026 · Engine · MI

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.

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.

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

February 3, 2022 I noticed a slight stutter in my 2014 GMC Terrain (approximately 111,346 miles) when accelerating after stopping at a stop sign. When stopped at the next stop sign the stutter happened again, and I aborted an attempt to make a left hand turn onto a 2 lane highway. Once the highway was safe again to make a left turn I attempted the turn, and the car died in the middle of the highway. There were no check engine lights, or other warning lights on at the time of the stutter, or when the car died. I was able to restart the car (no warning lights once restarted) and continue driving to my destination to drop my child off at school, and return home. Upon arriving home I researched the issue, and found similar complaints regarding the same issue of 2014 Terrains either stalling while driving, or having complete engine failure while traveling highway speeds. Upon further research I also found numerous complaints regarding unusual oil consumption. In 5 days I added 5 qts of oil, and took it to a repair shop February 10, 2022 where they added 4 quarts of oil and diagnosed a rear main seal (again no check engine light, or oil pressurewarning light). Bottom of my car is currently covered in oil from the massive leak. I purchased the vehicle used, and have changed the oil on the recommended schedule with 5-30 synthetic blend oil.

I bought it in june 2020. Used excessive oil. I kept adding oil. I thought it was an oil leak and took it in to firestone to get fix. As I was almost there the engine light came on and was making a loud noise under the hood. First warning of anything was wrong, no other lights showed on dash indicating a problem. I was driving when this happened. Firestone said really bad oil leak that damaged timing chain and lower engine. They said I need to replace the engine. Why didn't I get any warning lights indicating there was a problem before my engine was damaged due to excessive oil usage. I see this same issue has happened to other owners with this vehicle. I was driving on the highway and could have been in an accident.
