In March of 2025, my engine started knocking and had low power. I took it to a local mechanic and he said it was the classic 6.2L rod knock. I took it to the dealer in Decorah Iowa and they agreed that it was the rod knock from the recall. Since it was not covered under the recall, I had to pay almost $10,000 to have it replaced. It took over 4 months to get an engine and then it was finally replaced.

My 2019 Chevrolet Silverado 1500 with the 5.3L engine developed a severe tick, misfire, and rough idle at only 93,000 miles. This was diagnosed as a collapsed AFM lifter on Cylinder 2. GM 5.3L AFM lifter failure is extremely common in these trucks and causes sudden loss of power, misfires, and unsafe driving conditions. This is a known widespread defect, yet GM has not issued a recall. The failure happened without warning and required major engine disassembly. This should be investigated as a safety and reliability issue.

"The vehicle has developed a recurring ticking/knocking noise in the engine, worsening under acceleration, accompanied by excessive oil consumption. This is a repeat issue after a warranty repair on June 6, 2022, where all 8 lifters on the right bank were replaced due to AFM/DFM lifter failure. I believe the current problem is caused by metal debris from the initial failure scoring cylinder walls, rings, and bearings, leading to lower-end damage. GM denied coverage under Special Coverage Adjustment N242498000 despite the prior repair and matching symptoms in bulletin PIP5623. Johnson Motor Sales quoted $14,893.89 for engine replacement. The noise and oil loss pose a safety risk of sudden engine failure or loss of power while driving, potentially causing a crash."

When driving normal speeds to work on a county road, engine light comes on, service light comes on. There was a tapping noise and reduced power. Luckily, there was a sports field parking lot that I could pull into to get out of traffic. We had the truck towed to our house through our roadside assistance program so that we could determine what to do. If we had not been able to pull off the road as quickly as we did, we probably would have been hit by the semi that was barreling behind us. The truck had reduced power.

I was on my way to work and I stoped along the side of the road to help with a car accident. After helping the person and the ambulance arrived I went back to my truck. when I got in it everything was on but I noticed that it was quite and that-??s when I realized the truck was not running anymore. I tried to turn it on and off but nothing happened besides all the dash stuff came on. It had been making a ticking noise but it would go away after a certain speed. After the engine would not turn on I had a friend that is a certified Chevy mechanic take a look and he told me the engine seized. It took 2-3x the torque to crank it over and when he was able to do that he found lots of metal shavings in the oil. I been out of a vehicle for almost 2 years now because of this issue.

Lifter failure while driving on highway. Resulted in an immediate drop in speed taking me from 65 to 30 mph quickly, and having to cross three highway lanes of traffic in order to pull over. Lifter failures are well documented on the chevy silverado 1500 trucks with the 5.3V8 and the 6.2V8. Mine happened after the warranty period but there are many documented cases of owners having lifter failures at 3,000 miles.
