I had lifter failure on my 2021 Denali 5.3 at 10,600 miles. Dealer replaced all 16 lifters with new GM lifters with supposedly new beefed-up springs under warranty. I got the truck back in 3.5 days. Truck does have DFM. Time will tell...

[@JoseRodriguez-tx1qz]

So far so good? Or did something happen?

[@ernestyunk1927]

oh my gosh I have 20000 miles on a used 2021 sierra 1500. it came out of mexico then Canada. I had 15,000 miles on it when I bought. 5.3 liter engine base model work truck. Disc breaks arent wearing evenly. what is the warranty on the used gmc? The manual really sucks.

Hopefully they’ve fixed the electrical bugs. Every now and then the audible sounds in mine don’t work. No radio, no, turn signals, etc.

Dear followers!! Don't let the beautiful pictures confuse you . Anyone who buys a new car from GENERAL Motors the chance you threw your money into the trash is very large. In this company there is no customer service, the company's management does not care at all, if you have a problem or a malfunction, you can only pray to God there is a chance that the help will come faster. GM is a very dangerous company, be careful and keep your money safe.!!!Share so more peopl… See More

Beware of possible lifter issues. I have a 2021 GMC Sierra SLT and I have had collapsed lifters twice on my truck at 8,000 miles and at 13,000 miles.

[@normangreer2465]

Same truck here. Same problem here with less than 3,000 miles. Got it back and headed back to shop this morning with display show vehicle my stall. Steering failed, truck won't shut off, will move when in neutral. I regret ever purchasing this truck!
