2021 GMC Sierra 1500 Review

Name: 2021 GMC Sierra 1500 Review
Brand: GMC

Price Range: $27,000 - $53,998

GMC Sierra 1500 AT4 Crew Cab Pickup Exterior

The GMC Sierra is comfortable and can be equipped with a rambunctious 6.2-liter V8. But getting the big V8 drives the truck's cost up, reducing its value. Still, if you're looking for the best interpretation of the GM family of trucks, the Sierra could be it.

Valve lifter problem

2021 GMC Sierra 1500 SLT 4dr Crew Cab 4WD 5.8 ft. SB (5.3L 8cyl 10A)

I have a 2021 GMC 5.3L w/10spd transmission. I pull a 21’ cargo trailer w/2 Polaris Trail Rzr’s. Yesterday at 13,800 miles the valve lifter on #5 cylinder went out.
