AT4 / ENGINE REPLACED

[47AT4]

I bought a brand-new GMC 1500 6.2L AT4 back in 2025. Never have an engine recall. At 39K miles, lost power, and ended up replacing the camshaft and lifters. 2K miles later went back to the dealer for engine replacement. Is this a lemon-car or what?

Welcome.

Good luck on the new engine. If'n your not too worried about losing .00001 miles to the gallon, ain't nothing wrong with 10w30 oil.
