   6.2 liter engine failure @ just over 100,000 miles. Prior to 100k miles I had taken to the dealership for sporadic loss of oil.

Had to have the vehicle towed and the mechanical said the motor is shot, and related to lower camshaft bearing issue. The only warning signs were the low oil light which happened around the…

When checking oil, I would find that it was low 2 quarts of oil each time. I reported this to the GM Dealer and they did oil consumption tests and determined the oil loss was within GM tolerances. So apparently it is ok to burn a quart of oil every 1000 - 1500 miles. Then fast forward to January 2025, apparently my rear…
