Valve lifter problem
Rod, 09/02/2021
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. We were 80 miles from home in the middle of no-where. We limped home.
The truck is beautiful, pulls great and gets good mileage, but GM should let customers know about this kind of potential problem.
The dealer told me … today that it could take a month to get parts and get it fixed. I need the truck almost every day, but now I walk for a month! NOT HAPPY! I’ve been a GMC customer for 35 years and bought north of 17 new pickups. Never had this problem. When this is fixed I will have to look at other brands.
