2015 Chevrolet Silverado 1500

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.

January of last year, I was driving, coming off the highway, my engine came on and the system send to shutdown immediatly. I was close enough to my machanic, upon inspection, the AFM System failed at only 76,622 miles. This is part of the building issues with this value lifter problem I wanted to document it with the NHTSA as you are actively opening case for this ongoing issue with GM. i am hoping that a class action law suit will hopfully gain traction. this was a know issue, i was outside of standard warrenty, I was forced to replace the engine out of my own pocket to avoid having a truck worth almost nothing. I will bring this up with GM corporate also, reciept uploaded. Millions of 2014-present trucks and SUVs, while federal investigations specifically target nearly 878,000 to 1 million newer vehicles (2019–2026). GM should be helad accountable

When applying brakes at low speeds the brakes are unresponsive they sound rough and the vehicle does not come to a stop it skids forward, and an electric low whine occurs. This doesn't happen everytime. I took it in for Carvanas 30 day warranty and was told its because I drove it down the mountain grade while applying brakes and they didnt find anything wrong with the brake thus wouldn't be covered. Been seeing this vacuum issue with the brakes on this particular issue and seeing if I can get this resolved.

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.

The contact owns a 2015 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, the vehicle lost power steering functionality for approximately 1 minute. The failure had occurred while the steering wheel was straight or turning towards the left or the right, and the steering wheel was jerking during the failure. The “Power Steering” message was displayed, and there was an audible chime intermittently. The dealer was contacted, and the issue was discussed. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the issue. The failure mileage was 158,000.

The contact owns a 2015 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the brakes failed to engage while the brake pedal was depressed. The contact placed both feet on the brake pedal for the vehicle to come to a stop. No warning lights were illuminated. A dealer was contacted and made the contact aware of an unknown recall; however, the VIN was not under recall. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 187,918.

COMPONENT: Electric power steering (EPS) and electrical/power distribution. Available for inspection. FAILURE: My 2015 Chevrolet Silverado 1500 LT (5.3L, 4WD) intermittently loses EPS assist during tight low-speed turns; steering becomes suddenly and severely heavy. On one occasion the engine shut off completely while I was turning - steering went heavy immediately before the stall. The same events bring random Service StabiliTrak warnings, Tow/Haul messages I did not request, and loss of stereo audio and turn-signal chime, sometimes together. Shutting off, opening the driver's door, waiting a minute, then remote starting restores normal operation - modules appear to reset when the truck fully powers down. SAFETY RISK: Loss of steering assist plus complete engine shutdown occurred while turning. Losing both in traffic could readily cause a crash. RECALL: NHTSA 18V-586 (GM 18289, EPS Loss of Steering Assist) was completed on this VIN 2018-10-11. Eight years later the vehicle still loses steering assist, now with engine stall. GM's Part 573 report states the remedy only reduces EPS current draw so voltage stays above the 8.8V cutoff; it appears inadequate here. GM TSB 18-NA-161 describes this same symptom set and attributes it to high-resistance battery cable connections, a poor BCM ground at G218, a shorted B+ cable at the starter solenoid, or a faulty battery - a hardware condition never made subject to recall despite causing engine stall and loss of steering assist. INSPECTION: Hotchkiss Auto could not recreate the failure; the vehicle set numerous codes across multiple modules, making the fault impossible to isolate. Not inspected by manufacturer, police, or insurance. No crash, injury, or fire. PRIOR REPAIR: Two months ago I cleaned and tightened two grounds (front passenger wheel area, under driver's dash). Symptoms stopped two months, then returned. WARNINGS: StabiliTrak and Tow/Haul messages precede and accompany the failures. First appeared June 2025.

The contact owns a 2015 Chevrolet Silverado 1500. The contact stated that while his son was stopped at a gas station, while buckling the seat belt, the floor anchor pretensioner cable snapped off. The contact stated that there was no warning light illuminated. A Chevrolet dealer was contacted and stated that the VIN was previously under recall, and the vehicle was repaired in Maryland in 2016 under NHTSA Campaign Number: 16V209000 (Seat Belts). The vehicle was recently repaired at Lancaster Chevrolet in Lancaster, SC (1616 Charlotte Hwy, Lancaster, SC 29720), and the contact stated that the vehicle would be covered under warranty if the mileage was under 184,700 miles. The contact paid out of pocket to have the cable replaced. The cause of the failure was not diagnosed. The manufacturer was not notified of the failure. The approximate failure mileage was 200,000.
