My vehicle started making a knocking sound and eventually died on me. I barely made it to a repair shop to check out my vehicle, but had to get it towed back to my home from the repair shop after they told me my engine failed. This happened around 118,000 mileage. I found out that this issue is very common and needs to be addressed for this year and model vehicle. It could have ended very badly for me as I was on the interstate when it happened. Now, my vehicle is sitting and I am unable to use it. Engine would cost me over $12k for cost and repairs.

Not even 100,000 miles on it and the engine blew. Started with a lifter issue. Everyone I talk to with Yukons and GMC in general say it’s a problem. Just a search on the internet shows that they all have this issue… a well maintained car should not have this issue and it’s clearly a GMC issue and it needs to be fixed. The repair shop can’t even order me a new engine due to this being a real problem all over with GMC.
