general problems of the 2011 GMC Yukon

My Yukon denali xl gm engine that was put in on 07/2022 has already failed. It failed as I was driving down highway at 65 mile per hour. It failed on 04/12/2025. I paid almost $7,000 to have my engine replace due to the original engine failing in early 2022. Now the engine that I paid thousands of dollars for has already failed and has no compression in cylinder 4. I have researched this and can see gm is currently in litigation over car owners reporting engine failure due to either liftors or cams. My car should be considered in this class action lawsuit against gm. It's wrong for a company to take so much money from owners and use an engine that gm knew had issues and was faulty to place it into my vehicle only to have it fail and now make my vehicle undriveable and I am told it's another $8,000 to repair it. Gm should address this issue with my vehicle and replace this engine that I had put in in 07/2022. Gm was aware of this engine problem with my model car Yukon. Gm knew this particular engine that they used in my vehicle on 07/22 (a gm engine) had the issue that gm is being sued for and sure enough the engine has now failed in my Yukon. Please hold gm accountable for this and include my car in this lawsuit.

Recurring system problems: my vehicle continues to exhibit intermittent system failures, causing unpredictable and potentially dangerous driving conditions. These issues have included: engine stalling, braking issues, electronic system malfunctions].

There are several incidents reported regarding ongoing assessment with GMC interplay activity I have noticed this have become a dangerous drive ability inside acceleration controls governor sets whiling driving engine play transmission shifts this have gone beyond everyday practices during drive times this have been very noticeable during anyone time rpm gauges constantly disrupted radio functions remote controls are at play many problems are being serious illegal assessed during drive compulsive fuel guagement. I have been placed at dangerous risk by interplay noticability. Now slight tick sounds after full services sparkplug and wire as tuneup oil changes fuel services and coolant same recurring problems continued after serviced alignment services. Controls are very strong.

GMC shuts down while driving. Almost caused 2 accidents. Then it starts back up. Very dangerous!!!.

Engine coolant is usually water–based, and may also be oil. A three–valve–per–cylinder was originally slated for the ls7, and was abandoned imputable to design complexities. E85 ethanol should is an understatement to the ‘war on fossil fuels. ’ the l98 is a modified version of the l76, with increased power and reduced redundant hardware. A vee engine is common configurations of internal combustion consisting of two cylinder banks connected to a common crankshaft.

Keep getting traction control and stability issue warnings along with reduced engine power. Idles up and down and rough car was parked haven’t moved.

I have replaced the battery and alternator. My door locks keep locking and unlocking on the own while driving, all my electrical in my car dim and keep resetting, my gauges are going all over the place. My car will turn itself off. While stopped at a red light, it seems to want to go on its own. While not running, I get in to leave, and my key at times don’t want to turn over. Then at times I try to start it and it will tell me theft control and won’t crank. When I’m out of my vehicle at home, my car will lock itself when the setting is turned off. The problem has been going on for a year but only getting worse now.

Truck started sputtering while driving. I had it towed home and then towed to the dealer and they stated the lifters in the engine were broke and there was damage to the can shaft. Told me this is normal and happens to vehicles like mine regularly. I have only owned the truck three years and have maintained it well with low mileage. They told me it would be $6700 to fix. When I complained, the rep told me $5500. I asked for a supervisor who then stated that GMC would offset the cost and it was now $3311. It would seem that if this is a regular occurrence in vehicles like mine, GMC would do something to ensure it doesn't happen. In addition there is still no remedy available for the tamara inflator.

Air bag.

Travelling at speed on the highway (60 mph) , the engine light comes on and a stabilitrak message is shown. Power to the engine is dramatically reduced. Car shakes violently and it is difficult to get off the highway. A seconday message appears to check throttle body assembly. Very close to getting rear ended. This is a major defect that has to be addressed. It has also occurred on a 2014 GMC Yukon xl that we own.
