2015 Chevrolet Silverado 1500: engine failure

Filed Sep 15, 2026 · Engine, Transmission · IN

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 federal safety agency 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

At 144k I had to replace the passenger lifters because cylender 8 (linked to AFM) was stuck. I got that repaired. At 147k I had to get my passenger side lifters replaced again. 2 months later at about 152k I had to replace drivers side lifters. At this point 152k ive had all lifters replaced. Passenger side twice. Now at 157k my bottom end is bad. I was driving and boom no power. That could of been bad. Ive spent so god damn much money on this truck due to the AFM. Its ridiculous. Now I have to spend 8k on a new engine. Ive spent a total of 12k in repairs to this truck. There has to be something done to compensate. Because of your guyses shitty engineering im going into debt. Its insane

2015 Chevrolet Silverado complete engine failure. At 143,000 miles the engine failed because of the displacement on demand fuel injection system/lifters. Lifter failed without warning, destroyed the camshaft, cam bearing and crank and crank bearings. Chevrolet/GM were no help at all and took on responsibility for building defective engines they knew would fail after the warranty expired. I ended up spending nearly $17,000 to have a remanufactured engine installed.

86K miles smelled gas. Dealer replaced one fuel injector on the 6 cylinder rail. At 108K miles, catastrophic engine failure caused by misfire in the #6 cylinder. No compression or diagnostic testing done at initial fuel injector replacement. It is now my understanding that it is good practice when replacing one fuel injector, all should be replaced. After truck was inoperable at 108K miles, ran a borescope into the 6 cylinder shaft and noticed massive wash and scoring. Goodwill from GM was denied for an engine swap. Subsequent diagnostic testing revealed low pressure in all cylinder heads. I don’t put a lot of miles on this truck per year and suspect the problem compounded over time without notice. There was gas mixture in the oil, however this issue was never brought to my attention during routine maintenance and oil changes. I know there were issues with the 6.2L and didn’t know of parallel or residual issues with the 5.3L. Long story short, I had to go with an engine swap on a truck with relatively low mileage.

The contact was informed that the engine shudder was due to a faulty fuel management system, which caused the lifters to remain in the open or closed position.

I heard a sharp click like metal on metal, then I lost all power from the engine. I was on the highway close to rush hour and I was trying to move to the right side of the road and get off on the shoulder, the engine would start long enough to get off the road and then that was it. The engine was dead. I called for a flatbed tow truck through my insurance. I had no idea as to what had happened. However, I have read many reports of engine failure concerning the 5.3 v8 engine which I have. The Chevrolet Silverado 1/2 ton pickup was towed on a flatbed truck to Chevrolet, They found that the engine had dropped a valve in the #7 cylinder and some rocker arms, etc also had broken. The final billing was $7092.89 I was in traffic going around 60mph when the engine died and put me in an emergency situation. This could have caused a wreck. Several warning lights came on because of a dead engine. I do not believe any rep. has inspected the parts as this has become a common serious problem, it is all over the internet however I have not seen a Recall at this time. I sincerely believe GM should be responsible for this as it has been happening for years and years. Thank you for listening
