Given the apparent widespread nature of this lifter/rod failure, I don't think it is sufficient to be "satisfied" with the warranty and wait for repair. First, there are significant delays in getting parts and a common side issue is the lack of loaners available. Second, it is insane to think it is normal for these expensive vehicles to need a top end job at 3k, 5k, or 7k miles, with NO ASSURANCE that the issue won't happen again. My Tahoe was plagued with warning lights issues on three different occasions which I think was the pre-game warning (i.e. misfire of cylinders prior to failure). Has there been a recall issued? Is GM standing behind the explanation that it was a faulty batch of parts from a supplier? I've never received official notification of a recall and my lifters/rods failed at 7,000 miles on my nearly $80k Tahoe High Country 4WD. There was no communication from GM. But the Service Advisor at the dealership was well-versed on the issue ("yep, we've got another one. Hate to tell you it could be weeks for parts"). The only service bulletin i've seen on the issue says repair damaged parts on affected cylinder bank and send the parts to GM Engineering for evaluation. Is this common practice? Or does it suggest that GM is still trying to understand the failure mode. If it is the same "faulty parts" in the other four cylinders, why not proactively replace those while the top end is off the engine? Until GM takes the public position that it is a batch of faulty parts (via recall), it is going to be hard to convince me that this isn't a design issue, potentially linked to cylinder deactivation. There are some interesting videos on YouTube about the potential cause of this failure. The guys at the dealership I bought my Tahoe admitted they have seen quite a bit of this on Tahoes, Silverados, and its the same for Yukons and Escalades.

Well, at least here in Texas the Lemon Law say you have to allow for "Reasonable Attempts" to rectify the situation (among other conditions). And you probably signed a document agreeing to arbitration. So probably not as clear cut and easy to force a Lemon Law claim as some might expect. My 2021 Tahoe High Country had the lifter/rod failure at a little over 7,000 miles. Same story as all the others, dealer claimed weeks to get parts, only will repair one cylinder bank. They fixed it and immediately I got the warning lights again, which I think are related to cylinder misfire and perhaps precursor to yet another failure. Many references to subsequent failures in the public domain. Fortunately, I was able to convince the dealer to buy it back from me. Lost money on the purchase price as well as sales tax etc. but feel I've dodged a major bullet and avoided quite a bit of heartache and frustration down the road. Bought a Ford product, and will NEVER buy any GM product ever again. And NEVER is a long, long time.
