2015 Chevrolet Silverado 1500 engine problems

Filed Oct 8, 2026 · Engine, Transmission · IL

A lifter failed and caused an injector to fail and a push rod to bend. The truck has misfires on two cylinders now. The AFM system is a large issue known for 2014 and newer 1500 trucks as mine is a 2015. The truck is in need of a motor rebuild or replacement and the dealer I took the truck to for the work quoted me over $9000 for the work to be completed. The engine has less then 125,000 miles on it.

I am filing this complaint regarding a serious engine lifter/Active Fuel Management (AFM) failure in my 2015 Chevrolet Silverado 1500. The vehicle experienced a lifter failure that caused significant engine problems and created a potential safety concern while driving back from shopping: loss of power, engine misfire, severe shaking, ticking, check-engine light, stalling, inability to maintain speed, etc. The vehicle had approximately 200k miles at the time of the failure. The vehicle was inspected by a local mechanic, which diagnosed the problem as collapsed/failed lifter. The repair required/will cost approx. 3k or more estimated My concern is that this does not appear to be an isolated failure. Other owners of 2015 Chevrolet Silverado 1500 trucks equipped with GM's Active Fuel Management system have reported lifter failures, including failures resulting in engine damage and sudden loss of engine power or propulsion. A sudden lifter or related engine failure can create a significant safety hazard, particularly when it occurs at highway speeds, while merging into traffic, crossing an intersection, or in another situation where the driver depends upon the engine to maintain acceleration and vehicle speed. I am reporting this in hopes that GM can be held accountable as they knew about these defective lifters but did nothing but hide it.

Lifter for cylinder 7, part of the Active Fuel Management system, failed to open causing the truck to lose full power while I was on the highway without any warning prior to the incident. It could have caused an accident if It had happened during a busier time on the highway as I could not go the "flow of traffic's speed." It has been torn down and looked over to confirm the problem and full extent of the damage, by a dealership, with pictures of proof. This has left me without my vehicle for months due to needing a full brand new motor.

When on the highway and attempted to accelerate to pass in the passing lane, there was a loud pop, the truck rapid decelerated and my son was forced to drive off the burm to avoid being hit by a semi truck. It’s been determined that it was caused by a lifter failure due to the AFM system

My 2015 Chevrolet Silverado 1500 had an oil pump failure at 77,000 miles… Truck may be 11 years old but it only has 77k on it and the oil pump has already failed? Seems crazy to me, especially when I’ve changed the oil religiously every 3,000 miles.

The engine in my 2015 Chevy Siverado 1500 5.3 AFM lost propulsion, began to shudder and stall on the highhway as I was pulling out of my hometown. Speed limit 60 MPH. I returned home and the flashing engine light came on before I could get home. Sputtering I pulled into the drive but was concerned about mine and my passengers safety as I turned around on the highway and headed back home! This is the second time my lifters failed, as diagnosed by the repair shop currently diagnosing the issue.
