Engine replacement

[ANHannie]

Just found out the engine on my 2021 AT4 Yukon has to be replaced. 38,000 miles.

What was your oil (0w20) and your frequency of changing it?

Assume 6.2l, but please confirm what engine your vehicle has.

2023 Tahoe 21,113 miles 6.2 getting a new engine. 2 to 3 months not sure when. Good luck. Trying to get a email from the dealer of what happened to the engine. So far was told the bearings but nothing in writing. Going to report it to the NHTSA as a safety problem. Good luck

Dealer told me this is an issue, GM is trying to figure out which supplier(s) are involved, which explains why it isn't every 6.2. There are 17 6.2's in our fleet, and so far only 2 of them, one was a 21, the other was a 23. All of them have over 50k on them now, the 2 had the issue had less than 20k on them. It isn't service related, they all use the same oil, same intervals, must be as GM suspects, supplier parts related.

Sorry to read this. You are not alone with this issue, but that won't make you feel any better.

You joined the site just to post this -- and nothing else? How about some follow-up info?

Probably one of those that join the site just to add fuel to the fire and doesn’t even own a Yukon or Tahoe. They are on every forum.

I was thinking that same thing. Probably a Ford dealer posting. LOL
