Valve lifter problem
Rod, 09/03/2021
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.
Bad engine design

2021 GMC Sierra 1500 SLT 4dr Crew Cab 4WD 6.6 ft. SB (5.3L 8cyl 10A)
My 2021 GMC Sierra 1500 had to have new lifters and push rods put in at 3600 miles then again at 5200 miles had the same problem waiting on dealership and General Motors to get back with me.I think they should buy back this truck in my opinion nobody should have this problem with a brand new truck purchased in January 2021.steelworker96@gmail.com
Broke down at 1,236 miles

2021 GMC Sierra 1500 AT4 4dr Crew Cab 4WD 6.6 ft. SB (3.0L 6cyl Turbodiesel 10A)
Bought a 2021 AT4 with 3.0L Duramax. Ordered it and waited 4 months for it to arrive. Love the ride & engine. Had to be towed to dealer with 1,236 miles due to a "transmission module issue." Been 3 days haven't heard back. Think transmission might've blown. Wouldn't go in reverse, would go into reverse position but wouldn't move. Engine power was reduced & check engine light came on. The … 10 speed transmission was supposed to be solid.... be cautious

2021 GMC Sierra 1500 Denali 4dr Crew Cab 4WD 5.8 ft. SB (5.3L 8cyl 10A)
Complete failure needed to be towed in three times less than 500 miles. Power or computer problems and still trying to fix!
