Cover picture for the articleGM Authority has received a growing number of emails and messages from General Motors pickup truck and SUV owners experiencing valve lifter problems. Some of these owners are stating that their vehicle has been at the dealership for several weeks while waiting on repairs. The valve lifter issues seem to concern the naturally aspirated 5.3L V8 L84 gasoline engine and the naturally aspirated 6.2L V8 L87 gasoline engines, which can be found in 2019-and-later model year Chevy Silverado 1500 and GMC Sierra 1500 pickups, as well as 2021-model-year full-size GM SUVs, including the Cadillac Escalade, Chevy Suburban, Chevy Tahoe, and GMC Yukon.

GM has been designing and manufacturing poor quality vehicles since the early 70s. The last good GM vehicle I owned was a 1962 Chevy Impala. My 1972 Camero, 1978 Malibu and 2003 Saturn Vue all had major issues well before 70k miles, which is why I no longer buy GM products. Toyota Tundra is my current vehicle and I expect to get at least 300k trouble free miles from it.

Today’s engines are crap…. All my cars drove 200 thousand miles or more before I traded them in, never any engine problems.
