2014 Chevrolet Silverado 1500: engine failure

Filed May 26, 2026 · Engine · SD

I own a 2015 Chevrolet Silverado equipped with a GM V8 engine that experienced significant engine failure symptoms consistent with known GM engine defect issues and related recall/service campaign concerns. Prior to failure, the vehicle began exhibiting abnormal engine noises, warning lights, performance issues, and symptoms indicating internal engine damage. The condition worsened and resulted in major engine failure requiring extensive repair or engine replacement. The failure created safety concerns due to the potential for sudden loss of power and loss of propulsion while driving. Based on the symptoms, model year, and engine configuration, I believe the failure may be related to known GM engine issues involving internal engine components, lifter failures, AFM/DOD system failures, bearing damage, or related defects that have been the subject of recalls, special coverage adjustments, technical service bulletins, or investigations affecting GM trucks and SUVs. I believe the vehicle should qualify for coverage, repair assistance, recall-related repairs, or special policy consideration from General Motors due to the nature of the engine failure and the known history of similar failures affecting comparable GM vehicles. I am requesting that GM review the vehicle history, diagnostics, and failure condition to determine eligibility for recall coverage, special coverage adjustment, warranty assistance, or reimbursement related to the engine failure.

While driving to work a month ago (3/19/25) I lost the power to accelerate out of nowhere. And my truck started making this noise, what I can only describe as a winding up noise while trying to accelerate. I was going 55mph on a busy morning commute. There were no warning lights. I pulled over and shut the truck off. Checked oil (even though it was changed a week or 2 prior). Oil was fine. Let truck sit for 10 mins then tried to turn back on, it started but had that winding up noise when just sitting in idle, the check engine light then came on after it was on for a minute or so. Ran codes at home, and truck started making an additional rattle noise on top of the winding up noise when had to be turned on. One code was the crankshaft position sensor, we changed that out. Then the truck wouldn't start. Taken to Dealership, and they said initially they found a broken connector to the engine harness. Fixed that then truck started but still making the rattle/clunk type noise and louder than at home so they continued diagnostics because they said the noise sounds like a rod knock, so rod either being bent/broken/slipping. Further diagnostics found that oil and coolant are mixed along with metal shavings through engine so new engine is needed.

EVERYTHING, it started with spark plugs and boots which is normal, then all of a sudden one ignition coil after the other, then the transmission, now it's the valve cover gaskets, the ENGINE oil cooler lines, the rear main seal, the oil pan itself, like literally everything. The places I took it advised probably getting a whole new engine. Mind you I just financed this truck 2 years ago. The transmission cost me $6,700 dollars out of pocket because my power train warranty wouldn't cover it because some wire. I don't know but there is seriously big problems with this year make and model. Also, the catalytic converters are bad and the exhaust manifold. All these things can't be wrong all at the same time unless there was a major issue prior to me financing when Chevrolet spit these trucks out.

I have experienced engine failure in my 2014 Silverado 6.2L on 3 separate occasions. All caused by the AFM system. Rockers lock into the wrong position while transforming from 4 cylinder to 8 cylinder operation. The first two occurrences bent lifters and caused a failure to the catalytic converter. A certified GM service department at a local dealership replaced parts covered by warranty. On the third occasion the rockers locked into the wrong position, bent push rods, damaged the cam shaft and caused a failure in the catalytic converter. It was taken to the same GM service department at Lou Fusz Chevrolet. My 5 year warranty had expired and GM refused to cover the parts they had previously replaced a year prior. I was quoted approximately $10k for repairs and $16k for full engine replacement. After some back and forth with the service department manager I requested to speak with the lead mechanic. He informed me that it was an AFM system problem he was very familiar with. He stated to me that I would be better off taking it to a private shop and bypassing the AFM system as he was “working on” 10-15 vehicles a month with the same issue. At the time I had reached out to GM corporate about the issue and I did not receive a correspondence. I have all of the paperwork and receipts and all other service records dating back to my purchase of the vehicle in 2018.

During a recent trip while using my turn signals the entire dash would flash off and right back on. When I exited the freeway and turned onto a small side street making a u-turn the engine died without warning and all dash lights went blank. Loss of everything including power braking and steering. Then the info center kept flashing “ Service stablink soon.” On my return trip home the same message kept flashing. There are no codes set in the computer. Just all intermittent electrical issues. Unable to replicate the issues at home. The service trailer tow system also flashes once in a while. The loss of all power shutting off unexpectedly with the engine dying is a major concern.

Using a signal for lane changes causes cruise control to disengage, suspension messages and air bag failure messages as well as tire failure icon would all come on and when leaving the exit ramp and decelerating the engine would die and system would lock up without ability to steer. So dangerous. Then next trip all is good but the engine failing while driving has happened a half dozen times. The last incident was another engine failure during an exit from the interstate in November.
