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.

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)

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.

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!

Bought car in 2021 and a few months later car started turning off while driving. Check engine light came on..replaced sensors and all was good. Fast forward to a week ago...scheduled an oil change like I always do...check engine light came on and engine started rattling. Stopped driving immediately. Checked oil and there was none. Added 3 quarts. Took to garage to have them take a look at it. He did the oil change but doesn't handle engine repairs and believes it is my timing belt. The vehicle only has about 65,000 miles on it and is a 2014. Common occurance apparently with this vehicle that needs to be addressed.
