L87 6.2: “NHTSA to investigate potential for engine failure in nearly 1 million GM trucks, SUVs”

[schrimsher242]

Apologies if this is being discussed elsewhere, I searched and checked the “is this being discussed elsewhere” suggestions.

Just saw this article, looks like a recall may be coming eventually.

This applies to the L87 6.2L V8 in 2021+ Tahoes/Yukons.

NHTSA to investigate potential for engine failure in nearly 1 million GM trucks, SUVs

Complaints lead NHTSA to examine certain Silverado, GMC Sierra, Chevrolet Tahoe, Suburban, GMC Yukon and Cadillac Escalade trucks and SUVs.

It was only a matter of time. Spontaneous engine failure is a recipe for a serious incident. Fortunately, at least on this forum we haven't heard of anyone having a major incident outside of the inconvenience being stranded with a failed engine.

Toyota recently recalled the majority of their TT 3.5L V6 engines due to failure caused by machining debris eating up crank bearings.

Good. I’ve been dreading the day when my power train warranty runs out, which is in about a year. Hopefully by then, an engine recall is in the books.

GM made the bed, now they got to lie in it. They had faulty tooling, produced faulty engines, and the consumers paid the price (figuratively and literally) .. GM shouldn’t get off Scott free when people are paying mortgages for f*ckin trucks and being left on the side of the road.

Happened to my wife a few days ago with our kids in the car. 2024 YukonXL Denali Ultimate. She had the same thing has everybody else: without warning it shutdown on the highway. Fortunately, no injuries or accidents caused by it. But it’s only a matter of time.

The dealership says the engine needs to be replaced. I’m trying to do some research on what this does to the value seeing as how the replacement will make it on the CarFax. Does anybody know? Also, will it alter the title?

The dealership has no timetable on when they’ll be able to do the replacement. We are going up there today to pick up our loaner (which, to me is not comparable) so just trying to get all my ducks in a row before we go up there. Thanks!

@Tomg737 i would push back ******* the loaner vehicle. Especially since they have no timetable for how long you’ll be in it.

Check the dealerships’ used vehicle inventory on the lot and ask for one of those. They got money in their used inventory, they own them, and it’s not like you’re asking for something brand new. Make them have some skin in the game and they’ll be more motivated to get your vehicle repaired and back to you sooner. I wouldn’t take anything less than a suburban in your case.

I was highly skeptical that machining debris was the only, single, solitary, root cause of that.

The GX550 has never been part of the recall and has a different front main bearing part number.

The damaged bearings looked like a clearance issue far more than debris issue.

Replacement will probably show up on the carfax. Mine did.
