Vehicle robust engine design FLAWD!
I owned a second generation Yukon and I absolutely loved it over 200,000 mi on it never had a major problem with the engine. My biggest issue with the second generation was the right front hub. I decided to go with the 3rd gen thinking it would be the same experience. But I am so disappointed in the engine in that thing. I have the AFM and the dod and the lifters go bad on it constantly. I replace the engine with a remanufactured one and still after 12,000 mi got another problem with injector 7. The the lifter went bad again and that was after 12,000 mi. I wasn't even done completely breaking in the new engine or get a 6.2 l in there? It'll be a truck that you'll love for the rest of your days. GM. You have to do better with that engine design. The whole active fuel management is terrible.
