2021 LT Trail Boss has great styling, powerful engines, and tons of technology in a great package. A commanding view of the road, a nice comfortable interior, amazing Bose Stereo system, tons of storage and tons of space for adults in the crew cab. But there are issues, side mirrors are too small, harsher ride (which I expected), and DFM, GDI engines, and questions on the 10 speed transmissions. I recommend disabling DFM ASAP or using the L9 trick to overide the system, to help prolong the life of the engines from lifter failure. Mine is under warranty for another 18K miles, if it acts up at all its into the dealership for warranty service.

I have a 2021 Chevrolet Silverado LT since the warranty has expired and the vehicle is over 60, 000 miles I have had nothing but problems with my truck. I barely drive my vehicle, I work from home and it sits up the majority of the time the miles are highway miles. My truck has been in shop 3 times for repairs. The dealership ( Galleria Chevrolet) does not want offer a loaner or rental vehicle unless the repairs are covered under warranty. There have been several recalls regarding the Silverado and GM and the dealership are aware, but they try to sweep things under the rug and don’t tell consumers because they don’t want to pay for the repairs. GM and the Chevrolet dealership are trash, they are not supportive of their brand. American made cars are poorly manufactured and we pay the price for it. I will never support or purchase anther GM product nor Chevrolet dealerships.

I have had the 2021 Silverado LT 5.3 for about four or five months now and have put about 5k miles on it. I purchased used and right away had problems with the tire sensors. If you have a problem with these trucks they will likely shut off multiple computers within the truck (abs, TC, etc are all connected, all will shut off simultaneously). Fixed that and a couple of months later had throttle control issues. Truck would randomly rev up a few hundred rpm’s every 3-5 seconds while holding steady throttle. Went to get it fixed and nothing is covered under chevys warranty for any of these parts. Due to the throttle control issues the truck had carbon build up and caused speed sensor failure. Major computer issues with the trucks and all are very costly. AFM systems in these trucks cause issues. An eight cylinder is supposed to be an eight cylinder. Don’t try to make it a 4 banger Chevy.
