2015 Chevrolet Silverado 1500: engine stalls while driving

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.

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: the federal safety agency 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 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.

I purchased a Brand new Chevrolet Silverado 1500 LT Z71 in2015. While still paying on this vehicle I had an issue with the engine bogging down and it would almost die. It would jerk and shake terribly to the point it just shut down. I took to Royal Chevrolet and they found that it had a broken Valve spring on Cyl 7. This went on and on they had this vehicle for a total of almost 7 months before they put 1 last engine in it. The 1st thing I did was drove down From Michigan to North Carolina to visit my daughter. Plenty of Mountains and a lot of driving as I drove 14 hours straight by myself. The engine that they had just put in started Chugging and choking and it stalled on the highway going through the mountains and I was hit in the rear end and the other driver never stopped. I managed to get it running again. Prior to leaving for North Carolina I ordered what they call a tuner where I could deactivate the AFM system and stay in 8 Cyl mode at all times. I had it sent to her house. I installed the program. Keeping in mind #1 I was rear ended. And every single time there was an issue it was Cyl#7 on all the previous engines. I talked to the Lead man at Royal chevrolet about all the issues and he said they know all about it and its a joke. They tried it on Cadillacs back in 1975 and recalled every one of them and turned it off. On my way back home not 1 single issue in fact and I sill have it displayed on my dashboard I actually got 26.2 Miles per gallon in V-8 mode in the mountains. I have driven to NC every year since before I even owned that truck and have never seen milage before or since. The AFM system is nothing but a ploy to get people to buy junk. Could someone been killed? Most certainly. I told the manager 1 more engine and I have a Friend cut stickers of lemons out and put at the main 4 corners in our town. I still have that truck and currently have 128,000 miles on it and I had to pay $600.00 to fix it myself. And GM thinks its a joke. I called GM

I began to smell gas near my gas tank. Upon further inspection, I noticed there was gas leaking down the side of the tank. I then tilted my truck bed to look at the leak from above the tank and I noticed that the plastic piece connector coming out of the fuel pump housing to the supply line was pumping a stream of gas all over the top of the tank. I went to disconnect the hose and the plastic piece broke instantly fully cracking apart. Thankfully this was in my driveway and not driving as this would have been very dangerous. There was no warning light and this would have sprayed fuel everywhere, especially at speed. There are hot parts all over there and would probably resulted in a fire, and at the very least the truck to shut off while driving. I did not take it to a dealer as the damage was extremely obvious. The truck has never been in a crash and I’ve never changed out any components involving the fueling system, meaning that it simply broke apart on its own. This appears to be a common problem and yet it is not a recall. I had to spend my own money replacing the fuel pump and housing in the tank, as well as the supply line connector as the plastic on that also failed. I started smelling gas and then a few days later is when I found the issue, but I had been driving the truck, including at highway speeds. The truck has 100,365 miles and I’m the original owner.
