My 2018 Sierra 1500 6.2L started knocking and misfiring. Dealer told me it's the camshaft. Any one else have this problem? The truck has 64,000 miles. Of course, 4,000 miles after warranty.
I have a 2018 6.2lL that has started a ticking noise. Dealer has told me I have a bad camshaft at 44000 miles on truck. I have a warranty. Also have a hesitation from 1th to 2 gear.
