This might be a bit if long post.

Truck is a 2021 silverado LT.  5.3L

Just a hair over 30,000 miles.

 

So on 11/05 I got off work and went out to my truck.  Started and had a odd start.  Almost like the key or button wasn't held down long enough.  Didn't think anything of and drove home about 2 miles later and hard knock from the engine, hard shifting from all gears and a rough idle.

 

Dropped it off at the dealership on Monday.  Was not given a loaner and was not told how long it would be.

 

After going round and round for a month I finally talked to someone that told me the lifters went.  They didn't say why the went.

 

Then they told me it was running fine but the throttle is stuck wide open.  They tried to replace thr throttle body.  Nothing.  There now replacing the computer. 

 

Over a month at the dealership and every week no loaner is available. 

 

Corporate said they couldn't do anything about it.

 

This the 2nd time the computer had been replaced in this truck.

 

It's been nothing but a headache since I got this damn truck.  I'm ready to park it in Chevrolet's show room through the front window.  

 

My 2011 never had any issues over 350,000 miles and never replaced any engine parts in and it ran great when I traded it in.  Biggest mistake I've ever made with a truck.

 

Sorry for the long rant.

 

Just wanted everyone to be aware that there is an issue with the lifters in this truck and engine model that seems to go out around 30,000 miles.

Ya I've seen a few on here.  More or less just needed a rant.  Tired if dealing with all the ****** from this damn thing and spending more time in the repair shop than on the road.

Same issues here. Same year and engine. Rough idle, jerking, shuddering in literally every gear. What was the solution? Did it correct the issue?

The only solution for the lifters is to either replace them with the factory junk that will break again, or pay a shop to install after market lifters+cam+tune to delete the DFM junk. GM DOES NOT care about customer service and will only support you up to the warranty end. They know they have a lifter issue and have no intentions of fixing/resolving the issue.  

When my lifters went, luckily i was still in the warranty period other wise it would have been about $7K.

      Post your UOA, (used oil analysis) here

      By Black02Silverado · Posted

      Here's the second UOA on my 22 Wrangler with the Ecodiesel. This has 5k miles on AMSOIL Signature Series DEO 5w-40. The first one was dealer installed oil, no clue what it was, the second is what AMSOIL recommended, European FS 5w-40, Most of the Ecodiesel world is showing great results using the European MS 5w-40, I figured I would see how the DEO works. This is using an Ecoguard oil filter. It's my understanding this engine likes to shed aluminum.  We will see. So far I don't think this is too bad.

      Disable DRL's

      By revmanii · Posted

      I'm surprised nobody seems to offer a solution like the start/stop device I put in my new truck. Remembers my setting when shutdown. And while it still starts up in start/stop, it stores/evaluates what mode it was in when shut down and will change it whithin a second or 2 of startup. It'd be nice to have something like that for the DRLs.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      I will be doing that for sure, but I need to solve who has/ where I can find a bidirectional scan tool that will support OBD 1.5. I'm kicking myself because I ebay'ed a Snap On MT2500 that I didn't think I'd ever need anymore. D'oh!! I'd rather not buy another, so I'll contact a few local shops to see if they have one and how much they'd want to do the procedure. I'd rather have the ability to do it myself... I wish there was a modern tool that could do it all, but I'd have no idea what to buy.   The theory with the pulled timing is that it mimics a rich condition. The delayed spark causes incomplete burn and the O2 sensor picks up low oxygen levels. That's interpreted as a rich condition so the PCM pulls fuel and that shows up in the deeply negative fuel trims.

      An ultra wealthy man had the most beautiful daughter. But, there was a problem. Everything she touched would melt in her hands. No matter what, Metal, Wood, Stone. Anything she touched would melt. She could not feed herself. Because of this, men were afraid of her. Nobody would dare marry her. Her father was despaired. What could he do to help his daughter? He consulted doctors, scientists and anybody who could solve this problem. Finally one of them said, "If your daughter touches one thing that does not melt in her hands, she will be cured." He was overjoyed and came up with a plan. The next day, he held a competition. Any man who could bring his daughter an object that would not melt in her hands would be given billions of dollars to marry her. Three extremely intelligent and handsome young men took up the challenge. The first brought a very heavy steel rod, But alas, when the she touched it, it completely melted in a matter of seconds. He sadly went away. The second brought a beautiful diamond, knowing diamonds were one of the hardest substance in the world and would not melt. But alas, once she held it in her hand, it melted. He too was sent away disappointed. So now, there was one left He was very nervous & sweating. He approached the daughter & said, “put your hand in my pants pocket and feel what is in there." She did exactly what he asked. She felt something very hard. She held it in her hand, squeezing it as hard as she could. It did not melt & remained extremely hard. Her father was overjoyed. Everybody was overjoyed. She was finally cured. Nothing never, ever melted in her hand again. They married and they both lived happily ever after, raising a wonderful family. Question: What was in the the groom’s pants pocket??? Answer below ↓ M&Ms of course! They melt in your mouth, not in your hand. What on earth were you thinking?
