I had to have a new engine put in my Yukon after a valve lifter failure. We opted to replace the engine instead of purchasing a new vehicle because we thought that would fix the problem, and I would have basically a "new" car. What we did not know at the time is apparently, there are known issues with the Valve lifters is the GM engine. Shame on us for not doing the proper research, as there seems to be a widespread major issue with the GM engine and the valve lifters. Had we known this, we would have never purchased another GM engine.

Now, after only 61,000 miles on this new engine, I have major valve lifter failure AGAIN, and my mechanic says the engine is "toast!!!" It has been 3 years and 7 months since we had the engine replaced, but I do not drive a lot, and have only 61,000 miles on this new engine that cost us $6500. How can a major manufacturer such as GM design such a piece of crap? Why are they allowed to sell such a worthless engine to the consumer? What is there accountability for this widespread issue?

Who is the engine design engineer for GM? I am guessing it is perhaps, Goofy, the Disney Character! It certainly cannot be anyone who actually went to an engineering school, or even has any experience in designing a proper engine. A "backyard, self taught" mechanic could design a better engine. Shame on GM for not hiring competent design engineers. And shame on GM for taking advantage of the consumer who assumes they are buying a quality product.

I had my engine replaced 61,000 miles ago for a valve lifter failure that completely ruined my Yukon Denali's engine. This new engine cost me $6500. After only 61,000 miles on this new engine, I have again had a valve lifter failure that has ruined my engine yet again. GM has known about this widespread issue on all models with this engine, and yet they continue to sell this inferior product to the consumer.

If this was some unknown, crappy little car manufacturer with a small amount of funds to get their product out there, then it might be more understandable. Or if it was some "cheap" vehicle, it might be conceivable to have such issues. BUT, GM has been in business since 1908. From 1931 to 2022, it was the largest automaker in the world. (Toyota took that status from them in 2022) So, they definitely have the funds to design and produce quality products that don't leave the consumer with a pretty yard ornament when the engine blows up.

I will never own another GM vehicle, and I will be telling everyone I know about the issues I have had with my GM product. My next car will definitely be a Toyota or Lexus SUV. It is sad, because I have always tried to support American manufacturers. I will continue to support other products made in the USA, but not when it comes to my car.
