I own a 2023 GMC Sierra Denali with the 6.

March 23, 2025

By Leonard GODUTO from Wood Dale, Il

Owns this car

I own a 2023 GMC Sierra Denali with the 6.2 liter v8. The truck just turned 20k miles and my engine locked up. First GM had Active fuel Management, that was a problem causing engines to fail. Instead of doing away with the faulty system that deactivates cylinders while the truck is cruising, supposedly to get better gas mileage, they doubled down and came of with Dynamic Fuel Management, which deactivates even more cylinders at cruising speeds, causing even more V8 engines to blow at extremely low mileage. My truck has been at Al Piemonte Buick / GMC for almost two months now, waiting for an engine replacement, but guess what, this is happening to Chevy Silverados, Cadillac Escalades and of course GMC Sierras, so the engines are not so readily available! Making payments on a truck that I can’t even drive is very frustrating! My Sierra Denali is under factory warranty, so they say it will be covered, but when is my truck going to be repaired and returned to me! GM knows there is a major problem with both the 6.2 & the 5.3 liter V8’s cause of this DFM system, but they refuse to to do the right by their loyal customers and fix this flawed system. I have been buying GM vehicles since the 1980’s, this might be my last GM truck! Hope GM is listening to the multitude of complaints concerning these motors, the worst being 2019-2024 models. Very disappointing state of affairs!

I bought my 2023 gmc sierra truck a couple months brand new/used. I started having problems with the brakes. Took it to the dealership and they said there was nothing wrong with my brakes. I’m still dealing with that annoying noise on my brakes. A month ago my front dash screen went blank. Now today a new truck I can t drive my truck out of my driveway! I had no oil and it sounds like my truck motor is going to blow up. I had a couple months took my truck in the dealership to get my oil changed!!!! Then no oil !
