Totally Agree.. my 5.3 07 had 1 seized lifter at 130k... fix it and wait for one of the other 7 to seive as well... HELL NO ! I did an AFM delete, new cam solid lifters, reprogram the computer. RESULTS - Same fuel mileage, more responsive, more power! go figure

 

I am in the same boat on how I feel about this. I love my 2021 Tahoe but need it to be reliable. I just don’t have much faith in the model, even when I eventually get it back. Ours is in the shop for the 2nd time, currently waiting on a complete set of new lifters. They have not torn down the engine yet to be able to determine whether there is any additional damage (and whether a replacement engine is necessary), as they are waiting on the back-ordered new lifters first. No one can estimate when those will arrive (“could be two days or two weeks”), at which time I might be looking at a wait for what is likely a back-ordered replacement engine.

A replacement engine is the only way I would agree to keep this vehicle, as I cannot be convinced that running it with bad lifters for 2000-3000 miles after they became symptomatic did not cause damage to other parts of the engine, which could easily manifest themselves anytime, including after my warranties lapse.

This is a crazy time for this to be happening, as there are no loaners and virtually no rental cars available right now.

I’m surprised that you haven’t exceeded the lemon law requirements. I guess Maryland has some tough requirements. In NC, it’s 4 trips for the same issue or over 20 days loss of use within a year due to being in the shop. It sounds like you’ve likely passed those marks but maybe not in MD.

If I were you, I’d trade yours in now while it’s “fixed” and while used cars are selling at a premium. You can in good faith represent that it’s “fine” (as you’ve been told) and either (1) get one manufactured after 3/31/21 (allegedly the date the lifter supplier changed) or (2) buy a full size SUV from another manufacturer. As much as I like my Tahoe when it works, I plan to do (2) when I get mine back, because I’ll never be able to trust that it was fixed.

 

Have a 2021 1500 AT4. Bent pushrod at 9,000 miles, dealer replaced all lifters on that side of the engine. Today, at about 15,000 miles, engine light came on, took it to dealer, and they are going to replace the other side lifters. If it is worse then just a lifter swap then they said they will replace engine. Sad, as this is my first ever truck and GMC/Chevy. Makes me regret this large purchase, and totally lost confidence in this vehicle. Will share any more details I can get from the dealer. Sadly, no loaner or rentals available, so I rode my bike home 17miles in 100 degree heat. Terrible from a customer experience standpoint.

This can’t happen every 7-10k miles can it?! Lord have mercy.

attaching a photo of the first bent pushrod for reference.

 

It's hard to rely on cars lately. The problem is especially relevant for children who live far from school. It is convenient that now there is distance learning, but this will not replace the child's communication with peers

 

2021 Tahoe premier 5.3 and 7200 miles- dealer says lifters and will be 1-2 weeks for parts/ this is my 9th Tahoe/ so far 1100$ for rental and charged 200$ for the tow by GM assistance- will see how it plays out but 75k for this? Dealer said I’m the 5 th Tahoe this summer/ how about a recall on that date of manufacture GM? You know the rods are bending! Money Pit

 

Update 8/6:
Still no acceptable resolution for my request to replace other 8 defective lifters.(I had 8 replaced when the truck broke down in June.) Also, no resolution on getting my warranty extended. After these requests were denied I continue to call GM to ask for updates, I finally got a call back from them on Aug. 5 saying that they're discussing my request again with their supervisors and the dealership. While talking to the representative(Damian) I did mention that I was a member of this forum and was keeping this group updated on my case. Not sure if that will help but at least I let GM know that they weren't dealing with me as an isolated customer. Anyway, Damian said he would call me back next Tuesday with an update.....I'll let the group know if he really does and the outcome.

 

UPDATE:
Drove away 2 weeks ago with all new lifters (16 of them). Was again out of town for work, sitting in a parking lot with engine running for about 20 min. Engine started to feel kind of sputtery so I turned it off. Five min later started it to drive away and continued with sputtery feel, misfiring, ESC, Traction Control and Check Engine light came on. Ended up getting it towed from Raleigh to CLT, NC. That was Wednesday at noon and now, Friday evening, they still haven't looked at it. We are totally, completely done with this car! It makes me soooooo sad that Chevrolet made this beautiful, smooth, comfortable car but put a piece of junk engine in it!! We've spoken and emailed the dealership where we bought it (first time we've contacted them about this as we bought in MD), have emailed GM yet again and are now looking into a lawyer. I REALLY THOUGHT THAT AFTER ALL 16 LIFTERS BEING REPLACED WE'D BE GOOD!!! But now I just am going to work on our lemon law and getting every dime back from this car's purchase. Then, I'll get a 2023 Toyota Sequoia. Our GM days are completely over!!!!!!!

 

Darn, that's not good at all!!! Sorry to hear this since I was hoping replacing all the bad lifters would resolve this issue. Good luck with moving forward on the lemon law and please keep us updated on your progress. I would really be interested in what advice the lawyer gives you on this situation. As my update indicates, I'm working on getting the other 8 bad lifters replaced and my warranty extended. I probably will end up in your position with the lemon law track though.
I'm about to be a Toyota customer as well:-).

 

Here's an interesting article I found last night.......

https://gmauthority.com/blog/2021/08...omment-1348325

I paid close attention to this particular paragraph:

If the customer has experienced prior valve lifter failures, dealers can choose one of three options: replace one bank of lifters and offer the customer a 60-month, 100,000-mile Powertrain Component Coverage Letter, replace the entire engine, or reach out to the District Manager of Aftersales for further guidance. The solutions are similar for a customer that has experienced valve lifter issues in the past and had one bank of lifters replaced. In this case, the dealer can replace one bank of lifters and offer a 60-month, 100,000-mile Powertrain Component Coverage Letter or reach out to the District Manager of Aftersales.

NONE OF THESE OPTIONS were even mentioned to us during any one of our many visits to the dealers for lifter replacement!! Looks like an extended warranty is on the table! GO for it people!!!

 

Hello again you wonderful people from the internet! we got out truck back on on July 23, they called us and told us to pick up the truck out of the blue 15 minutes before closing the shop so it was very weird for us but we went! they told us that they replaced all the lifters so we were happy of getting our truck back! as we got on the truck we realized we didn't have any more gas left in the tank? we left it full! (lol)

so we drove our truck for approximately for 600 miles and it finally broke down again on the 4th of august ( same issues sputtering engine, kicking and all TC and engine lights on) we left it there and we haven't moved it yet. tomorrow we are calling the GM road assistance thingy and get out truck back to the dealership where they fixed it.

let's see what they will say now, but from what I can see in this forum there's no escape to this curse.

I will let you guys know what happens after!
