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.

I have a 2017 Chevy Tahoe with 77,000 miles on it. I will have it 4 years Labor Day Weekend. I get all the regular service and oil changes on it in a timely fashion. Last week I was driving my daughter to a friends house and there was a tapping sound. The car did not sound right. Suddenly the engine light illuminated and was blinking. The car smelled of gas. Thankfully I wasn't too far from home. I had to drive on a highway to get back to my house. I could only go about 30 mph. It was very dangerous. I had my hazards on but people were still beeping at me since I was causing a safety hazard for myself and others. I managed to get home safely and called the dealership. I dropped my car off the next morning since it is not drive-able. The service rep said it was going in as an emergency. After 5 days they finally looked at it. They did not give me a loaner. If I wanted a loaner I was required to pay $46/day. The rep said the repairs to my 3 year old car wont be covered and it will cost over $5,000 to fix the engine. It is a known engine issue to Chevy corporate bulletin 15-06-01-002H Engine Misfire/tick noise, malfunction Indicator Lamp Illuminated. It is common in 20-15-2019 Tahoe and Suburban. I had to borrow a 12 year old car to drive around my 4 children because my 3 year old car has a bad engine. Ethically how can Chevy require their customers to cover a cost of an engine that they know is faulty. There was nothing that I did to cause this issue. I will never purchase another chevy. SHAME ON PARAMUS CHEVROLET.

Vehicle is misfiring and stalling due to a fuel injector problem similar to the bulletin n182198000. This bulletin should be valid for any state. Gm is having major issues with fuel injectors. The problem is that this vehicle misfired which felt like a jump and I cause me to hit the brake thinking it was something else and it misfired again which made the vehicle slow down faster and almost cause a wreck on the highway
