Consumer Description

We have owned the car for five years. We bought it new in 2020. Now, the engine has completely failed. It has the same problems all the recalled GMC Yukon Denali XL 6.2L V8 engines have; lifters are not functioning, cam shaft is destroyed, rods are bent, oil is pooling and the aluminum engine has melted. The engine light suddenly went off and we didn’t have acceleration. The vehicle started “puttering” and didn’t drive well. No warning at all. This is a known issue with GMC (which I just found out about) and I find it absurd I have to pay $26,000 for a new engine which will most likely have the same problem. Luckily nothing happened, but if that happened on the highway with my wife and three young kids in the car it could have been a nightmare situation.
