Bought a 2021 GMC Sierra SLT used 18k on it.

February 21, 2025
By Chris from Colorado
Owns this car

Bought a 2021 GMC Sierra SLT used 18k on it. Drove it 350 miles and the left band of lifter went bad,bent push rod and rocker arms. Got back and drove it about 300 miles and had the oil changed to make sure there was no metal in it from the work that was done. The next day I started up and it had 70+ pounds of oil pressur. Took it the dealer and now it is getting a new oil pump. This is a very nice truck to look at and drives nice but you should not have these kind of problems with a 50 thousand dollar truck. GM has paid fo6 all the fixes. Waiting to see what is next. Don't want to trade it in to give someone this problem. It suck to get a lemon.
