I am the original owner of a 2014 GMC Sierra 1500 (VIN: [XXX] ) and began experiencing serious mechanical and electrical issues while the vehicle was still under warranty around 40,000 miles. These included engine RPM fluctuations at idle, vibrations under acceleration above 65 MPH, and intermittent misfiring — all symptoms that are now believed to be early indicators of defective lifters or valve train components. I also experienced repeated electrical failures including a rear turn signal malfunction due to melting/corroded taillight sockets, a thumping rear-end noise, differential knocking, and body panel issues (hood lifting at highway speeds). These were reported multiple times to authorized GMC dealers (Mike Haggerty GMC and Rizza GMC), but I was told there was no issue or no repairs were made. GM refused to assist when I escalated the issue in 2017 via a detailed email, despite all problems occurring within the warranty period. I’m now dealing with a persistent ticking sound from the engine and loss of power, which matches widespread reports of lifter failure in GM’s 5.3L/6.2L V8 engines. These failures pose both a mechanical and safety risk due to stalling, misfiring, and potential electrical fires (in my case, from a failed taillight socket). A class action lawsuit ([XXX], et al. v. General Motors LLC) has been filed regarding these known defects, yet GM has not issued a recall. I’m filing this complaint to add my case to the record and urge the federal safety agency to investigate these issues. I have full documentation of the original complaint and am willing to provide it upon request. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

What component or system failed or malfunctioned, and is it available for inspection upon request? How was your safety or the safety of others put at risk?: The truck just stalls and dies without warning, all lights go off inside and outside and all power is lost. From digging on the internet, I found out the problem is due to one or more rusty/defective connection to ground which stops current from flowing and therefore stalls the vehicle and turns everything off. When the truck stalls, power steering and power assisted breaks are not available and this makes the truck very difficult to guide/stop for most people, making it a significant safety risk to occupants as well as others as the likelyhood of a collision increases significantly. In addition, since all electric accessories are disconnected, warning/flashing lights can not be turned on to advise others that the truck has stopped. Has the problem been reproduced or confirmed by a dealer or independent service center? The problem is hard to reproduce because it happens at random times, it has happened to me at least 5 times in the last month or so. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? NO Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? NO warning messages or other symptom.

The truck shuts off while driving which disables the power steering, engine and power braking. The electrical systems seems to reboot and turn back on after a second or two. This also happens occasionally while driving at slower speeds and turning the steering wheel or after hitting the turn signal. I have had the entire electrical system and engine shut off while doing 50mph on the high just because I turned my turn signal on. This happens every 4 weeks or so. You can tell it is about to happen when the headlights start deeming when tapping the brakes or using the turn signal. It usually happens when the truck is in motion. It has happened in all temperatures. After it happens the console states "stablitrak is disabled".
