2018 Chevrolet Silverado 1500: fuel pump failure

Filed Nov 5, 2025 · Electrical · ND

Number one electrical system left side wire harness manufacturer installed in properly, not watertight and ran through a pinch point causing wires to break. Safety was put at risk due to power failure from fuel pump and brake lights failing which could’ve caused a potential accident. Been confirmed by an independent service center. Reached out to the manufacturer. They said there was no recalls. It was very unhelpful. On the failure happened a light did come on. Number two media end navigation system this is a safety risk because at certain times it will switch between screens at will by itself. They will also put calls on hold, causing you to instinctively reach for your phone and taking your attention from driving as well as switch off of navigation moving your attention from driving, this is a clear definition of distraction and not serving the purpose it was created for which is also been confirmed by an independent shop. I reached out to GM. They said there was no recalls. And there is no service light. P.s.I just found out that I could make a complaint here so I do not have any of my old documentation. I just went to the dealership this morning to try and get some help and I had no luck. They would not be helpful at all. They just want to sign me up for a service meeting and charge me another $500 to look at it only to tell me they can’t order me a wearing harness again.

The plastic fuel pump module (GM part # 13510918) has cracked. The top flange that rests against the top of the fuel tank has an approximately 3 inch crack. The indications were a failed EVAP Check Engine Light PO442 (Small leak). The vehicle had less than 35K miles at the time. Contacted dealer who stated that it was a common problem. Also contacted GM but they provided no assistance. This crack could lead to fuel leaking from the top of the tank. The issue required the fuel pump module assembly to be replaced.

UNKNOWN I had performed preventative maintenance this evening, fuel filter replacement and noticed after I pulled the fuel filter from the housing and tipped housing back upright, there was what appeared to be brass/gold metal shavings in the bottom of the housing in a little puddle of fuel. If there is metal shavings in the filter, that is a problem. Not sure if it would be fuel pump, or lift pump. Truck runs fine, I do get some hesitation from time to time, but not always. No warning lights/indicators, no water in fuel indicator, or presence of water in fuel. I am worried about safety if metal shavings contaminate entire fuel system, plugging injectors shutting down the truck on the interstate.

When I opened doors the fuel pump turns on, while I'm driving it shifts and runs funny and you hear popping noises. The gauges mess up and radio turns on and off. Like its being hacked.
