Take it to the dealer. Also search broken valve spring for silverados. Seems to be a very common issue but I do not know for sure that your symptoms match or not. Again though, take it to the dealer and take advantage of the warranty.

After getting on YouTube I'm sure that's what it is.....and it sucks, makes me feel I have an untrustworthy truck

What year is your truck? Which engine (5.3 or 6.2)? Sorry to hear about this. Makes me fear that for the future of my truck. DISGUSTING how a truck can bet $45k + and have boat anchor engines in them.

Must be why I'm seeing a BUNCH of TB's sitting in used lots with under 10k miles on them. People shagging their doomed to fail V-8's. Very sad. I feel like I made a mistake buying one.

Ok, let me correct myself. Must be why I'm seeing tons of used, late model very low mileage GM products that are V-8 powered, usually TB's sitting on lots. Feel better?

Hey man.
Same exact thing happened to me on Wednesday. Same lights everything. Had mine towed to the dealership. It’s lifters. After doing research it seems to be happening a lot to certain trail bosses. I was told that trailbosses built between September 1st 2020- March 31st 2021 were put out with defective lifters. I’m also reading the parts are on back order for 1-2 months. It is covered by the warranty however they will only replace one at a time. You have to wait for the others to fail for them to replace them even though it’s a known issue. I’m fighting Chevy to have them all replaced now otherwise it’s a guessing game as to when it will happen again. I travel alot, luckily this time it happened when I was close to home.
