My 2017 Chevrolet Tahoe LT 4WD with a 5.3L engine experienced sudden drivability issues related to confirmed AFM lifter failure, including severe engine misfires (P0300), rough idle, shaking at stoplights, and significant loss of power while driving uphill and under load. The vehicle has approximately 140,000 miles and has been consistently maintained through Chevrolet dealerships. The condition has been diagnosed by Premier Chevrolet of Carlsbad. The engine experienced loss of power during operation, creating a potential safety concern when accelerating or driving in traffic conditions requiring consistent engine power. This issue appears related to widely documented AFM lifter failures on GM 5.3L engines.

The factory-applied clearcoat on my 2017 Chevrolet Tahoe is failing and delaminating. The clearcoat is peeling away from the base coat in sheets, exposing the underlying paint to the elements. This deterioration occurred without any external damage, collision repair, or environmental abuse. The vehicle has 76,000 miles and has been regularly washed and maintained throughout ownership. The affected areas include roof and door panels. The failure began as clouding and hazing of the clearcoat and has progressed to active peeling and flaking. This issue appears to be a widespread manufacturing defect. Multiple class action lawsuits have been filed against General Motors alleging defective paint and clearcoat application on 2015–2020 full-size SUVs produced at the Arlington Assembly Plant [XXX] et al. v.

It has happened several times when going slow the breaks get really hard to stop the vehicle. Otherwise breaks are new work well. One time I hit my garage as I tried to move it slightly forward. Another time I was slowly moving forward & tried to stop at a driveway as person was walking by. I pressed breaks down as far as the could go.
