Anyone else have multiple issue regarding the lifters? I purchased a demo truck with 3900 miles on it back in early May. Started having engine issues almost immediately and had gotten all my lifters replaced recently, with under 7,000 miles on the truck. Spent almost a month at the dealer and finally got it back. They replaced all the lifters the first time and then a few weeks later it started having issues again.

 

Luckily with the market conditions today I was able to trade out and get a newer one but I gotta admit I'm concerned.

 

Anyone else dealing with this issue repeatedly?

There are a few threads on here about this topic. There was a run of engines made prior to March 4th 2021 that were having failures. I forget the exact dates but it was small span from January to March that had problems.

I hate to hear that.  Mind just started doing it today.  Dropped it off at the dealership and they said it was becoming common.  They had 5 in the service for it now.  Due to a part backorder, may take 3-4 weeks to complete repair.  Friend had same problem, but they were able to fix his in a couple days.  So far, his is back to running good.  I hope they get this figured out soon.

2021 RST CC 5.3 5485miles went in on September 10 hopefully I’ll get it back this week. All 16 lifters are being replaced. Now I’m wondering if I should trade it off and wait for the 2022s. 
 

My question is how long this fix will last before there’s another issue!

 

Engine build dates with issues are from September 2020 till March 2021.

      I have a 2022 trail boss lt that has about 6100 mile on it now. Bought it brand new in may 2022 and it seems like the drivers seat leans to the left towards the door. Almost feels like Im gonna fall out of it and no matter how I adjust it it seems the same. Visually it looks like it sits level and is fine. Is it possible something is broken inside like the frame? I would assume the frame would have to be sturdy. Is there any place that sell a better bottom cushion?

      My l84 5.3 cracked some pistons now thinking of doing a light hone but wanted to know if it would even save the engine ? The scratches are pretty light my nail doesn’t get stuck but I do feel em. The pours on the other hand I’m not sure what could have caused those little things ?

      Hello all, My Sway bar was hitting my CV axle, as the title says. So I crawled under some trucks at the dealer to see what stock trucks are like and it turns out that the new TB/AT4's have longer end links then my 2020 TB. The new end link has a 3 inch rod vs the 1-3/4 inch OE part.
       
      The part number for the longer end link is P/N:85590925

      I have a 2020 RST with the 3.0 LM2 Duramax with 79k miles… the flywheel failed when I was driving down the highway and left me dead in the water.. I had it towed to the dealership 4 weeks ago and they called today and said the transmission and the engine needs to be replaced. Has anyone experienced this with their trucks? I never towed anything heavy and was religious with service.. luckily all covered under the 100k powertrain warranty…

      Hello everyone. I've recently purchased a 2020 Silverado 1500 from a dealership. I found out late in the sale that the truck was used as the dealerships "loaner" which didn't really bother me even though I know people beat up those vehicles. Anyway, I'm pretty in-tune to vehicle sounds and I had a couple of questions regarding noises I'm hearing from my vehicle. 
       
      The first is a clunking noise and a physical jolt when I shift from Drive to Reverse. I have my foot on the brake and am on a flat surface. I notice it a lot after I've been driving for a while and go to back into my garage. I took the truck back to the dealership and they chalked it up to bad U-joints. They slapped 2 fresh sets on, but I've still go the issue. Any ideas what it may be? I don't feel like anything is going to fail, but I also don't like the sound and don't think it should be that way. I have another service appointment next week and I'd like to help them out with ideas considering they don't really seem to care.
       
      The second is a ticking noise coming from the undercarriage. I' got under the truck today and believe it's coming from the rear portion of the engine, but I'm not for certain as I've never been beneath the truck while it's been on a rack. The noise cannot be heard when standing at the front with the hood up, but I can hear it very noticeably when standing at the driver's door. I do not hear it as the engine is heating up, but that could be because every other component under the hood is loud as h*ll while the truck is heating up. Once the engine is approaching operating temp, it's very noticeable. As you can hear from the short video, it's every .5 to 1 second or so and is always present during idling. Again, may not be a big issue, but I hate hearing things on my vehicles that I can't attribute to something else.
       
      Thanks for reading my ramblings. I can try to post longer videos if anyone needs. Thanks in advance!
