URGENT: New 2022 Yukon XL Denali Engine Failure

[Srf471]

I took delivery of a brand new 2022 Yukon XL Denali on 8/11/22. Exactly two weeks later the dealer had to pick it up with a flat bed due to multiple system warnings including check engine light and running rough with engine noises. I still have not received any news whatsoever from the dealer. Frankly I’m shocked and getting pretty angry. It was assembled in 7/22 and had less than 10 miles when I drove it off the lot. 6.2L engine. Anyone have a similar situation? Could this still be the pushrod issue? I’m thinking I may just demand a full and complete refund. Any insight would be greatly appreciated. Thank you.

It could be the valve spring issue that was causing lifter failures, but I thought those were all purged from the system. Even though you have a late year build for the 22MY there is no telling when the engine was built. Hope it works out for you and I would be pissed off as well.

Sound like the lifter or pushrod, which could lead to the cam. I guess this issue is not resolved being such a recent build. Sorry to hear. takes all the joy out of a new purchase. keep us updated, good luck.

Very sorry to hear this and I would be very pissed off as well. Please keep us updated about how your Dealer and GMC respond to it. I have a 6.2 2022 also. So far no trouble.

Thank you all. I called the dealer again this morning and again I’m waiting for a call back. I then called GMC to explain the situation and get everything on the record. If it is the lifter/pushrod problem - what should I request be done above what they propose? I read they may try to replace only one side and not the other - what does that mean exactly and what specifically should I ask them to do?

Look up on GM authority. I believe if it’s before 8,000 miles they replace one side.

The engine on my 2022 Yukon Denali (6.2L) with 13K miles failed with no warnings or messages. We were on a road trip and we are waiting for our dealer in Minnesota to get it home from Montana and fix it.

Thank you both and please keep me posted mbrunn. Curious to see if similar issues.

 

[Srf471]

Dealer just called me and said it has one bad fuel injector and that they are on back order and not available. Could this be true? Does this sound right?

Could definitely be.........same kind of condition a bad coil would indicate, missing (either fuel or spark) on one cylinder, running rough, etc. Really sucks on a brand new vehicle........I'm surprised (but I guess not) that the part is unavailable.....Did they put you in a loaner?
