    2022 Z71 Suburban 6.2L bent lifters

    My first sign was a whole lot of warning lights "Service ESC", "Service Trailer Brake System", "Service Steering Column Lock" and "Service Traction Control", among others.

    Made without AFM module

    I have a neighbor who ordered a Suburban without AFM (his choice). Wasn't aware that was something one could do.

    2021 Z71 traction control failure

    This is almost certainly the pre-game for a lifter failure. That's what happened to me. I got all the warning lights before the knocking started.

    2022 Z71 Suburban 6.2L bent lifters

    Lack of recall likely not due to lack of availability of parts (they are apparently getting parts to repair anyway). And if there was a recall, GM would get with suppliers to expedite production of parts with correct spec to conduct the recall. In fact, they would announce the recall, and then...

    2022 Z71 Suburban 6.2L bent lifters

    With regard to the "bad parts" vs. "bad design" issue, if it is simply bad parts, why hasn't GM issued a recall? They know what batches of parts, or mfg. dates of vehicles were subject to poor quality (due to covid?). I was also under the impression (perhaps incorrectly), that there is a new...

    Faulty Lifters took out my Escalade 2021 - 2 Trucks Down and Need advice

    I dumped the Tahoe and got a Lincoln Navigator. Could not be happier. I like it better - except it doesn't have four wheel drive. I probably can do without it fine.

    2022 Z71 Suburban 6.2L bent lifters

    I don't understand the perspective that this lifter issue is due to a bad batch of parts. If so, GM would have/should have announced a recall, as they would know what vehicles had the "bad" parts. The fact that this issue continues, and now is seen in 2022 models, is evidence (in my view)...

    '21 Tahoe Z71 alignment - anyone else?

    I had this on my 2021 Tahoe. Scalloping on the outer edges of front tire. Took to the dealer and they claimed it was due to improper tire pressure. We all know that low pressure causes wear on both inside and outside edge. Over pressure causes wear in the center of the tread. Despite the...

    2021 Tahoe issues

    Not to pile on here, but my 2021 Tahoe High Country had many issues. Bad (foggy) tail light from factory - replaced after delivery. Then I had water sloshing around somewhere in the roof in the rain, as if the drains were not working. Also had scalloping on the front tires indicative of...

    Lifter Issues on ‘21s Being Delivered to Dealers

    This isn't a case of bad parts - lifters out of spec from a supplier. This is a design issue. GM knows it, and will stall as long as possible. I'm willing to bet the failure rate in the 2021's is much higher than in prior years. When mine failed at 7,000 miles, and based upon the service...

    Sold my new tahoe

    My lifters failed at 7,400 on a new Tahoe. After seeing how common this is on various forums, I dumped it. Sure, it might be fixed under warranty (how many times?), but the inconvenience with no loaners, and my fear of my family being stranded on a highway trumped all. I sold back to the...

    Lifters

    I'll second the presumption that it isn't bad parts. If it was bad parts, the "batch" could be isolated and a recall would be issued based upon manufacture date and knowing what vehicles go the bad parts. GM hasn't issued a recall. The point made in a post above that they only replace the...

    2021 Tahoe with 6k miles mine has already had a head off

    So if it is indeed bad valve springs for certain manufacture dates, why hasn't GM issued a recall? I've seen several references to initial repairs and then subsequent failure, with what I would assume are "in-spec" parts from the suppliers.

    Lifters

    I beg to differ on the view that it is faulty parts. If that were the case, GM would have announced a recall. They would know the supplier of the faulty parts, the shipment lot of the faulty parts, and the vehicle manufacture date of the vehicles with the faulty parts. The fact that there...

    2021 Tahoe 5.3 engine failure at 4,800 miles

    Yes, I had those same code issues one week before failure. Took in and they "replaced a module". Less than one week later the valve spring/pushrod failure, and the same codes reappeared. Wonder if they are related.

    2021 Tahoe with 6k miles mine has already had a head off

    Well, in my view a recall wouldn't solve the problem, as it isn't faulty parts that could be replaced. It is likely a faulty design. And if they only replace affected parts on the cylinder bank that is impacted, it can happen again or on the other side. I wish everyone good luck, and hope GM...

    2021 Tahoe with 6k miles mine has already had a head off

    You might be surprised at what they would offer. Friend just had the Porsche Dealership call and offer to buy back a 5 month old Cayenne for what they bought if for. Few high end cars on lots due to chip shortage. Was told by a Ford salesman that Ford has shifted production to lower-end...

    2021 Tahoe with 6k miles mine has already had a head off

    One last update. Went to dealer yesterday and told them I wanted them to buy the car. They did. Owned 7 months and 7,400 miles. Got 78k on a MSRP of $79.5k. Sure, I'm out the sales tax, but feel i've dodged a major headache down the road. Don't know whether to attribute the sales price to...

    2021 Tahoe with 6k miles mine has already had a head off

    Well here is an update. As noted above, my 2021 Tahoe High Country started getting numerous warning lights, fixed by the dealer, and less than a week later at 7,400 miles I got the knocking and shuddering, which the dealer identified as the lifter/pushrod issue. Service Advisor called...

    Would love the addresses, and I'll be happy to share my correspondence with them. There is power in numbers.

    2021 Tahoe with 6k miles mine has already had a head off

    Just happened to me at 7,300 miles. This following the Brake issue last week that required module replacement. Funny thing is that after the engine started knocking today, I got the same warning from the "replaced module" Namely ""Service Trailer Brake System", "Service Traction Control"...
