The high pressure fuel pump has failed at only 60,000 miles. My Safety along with the safety of others has been put at risk from major loss of power... not safely stopping the vehicle due to fuel pressure malfunction. Certified Chevy Dealer diagnosed high pressure fuel pump Come to find out from the dealer... a warning sign was the electric start button not working. Engine light did NOT come on till after the truck had major power loss/ misfire/ stall.
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.
The component or system that failed or malfunctioned, FUEL PUMP ( METAL FLAKING IN FUEL SYSTEM ) has caused 1 or more CYLINDERS to FAIL. It is available for inspection upon request. My safety as well as the safety of many other motorists was put at high risk due to the fact that I had a 40ft. trailer hitched to the truck at the time the engine power was reduced. thus causing my vehicle to loose power while driving on a major highway. The 2018 Chevy Silverado was diagnosed by the Chevrolet Dealership doing-business-as ASCHENBACH CHEVROLET located at 925 East Main Street, Wytheville, VA 24382. The vehicle has not been inspected by the Manufacturer. When pressing down on the gas pedal, the truck would not accelerate as normal, then a message appeared on the dash-screen ENGINE LOOSING POWER.

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.
Faulty injector connectors get a loose connection and make truck shutter and check engine light come on. This has happened 3 times already and had to replace one faulty plug. This is all over the internet from other l5p owners. Yet gmc want do anything
Hearing unusual powertrain winning, lugging on a hill to the point of shuttering before it downshifts, and then very harsh shift. Very harsh shift from first to second gears, and then again on downshift from second to first. Today 11/19/2020 I had the cruise control set at 70 mph, and once it started lugging down it downshifted and took off like the engine kept running wild. I tapped the brake pedal to cancel the cruse control, the brake pedal had no effect in canceling the cruse this vehicle just kept running wild. I even pushed the main cruise power button on the steering wheel foe what seemed like an eternity, still run as if it was possessed. After about 45 seconds, and just as I made up my mind that I had to kill the ignition switch, it calmed back down to the normal harsh shift, but didn't run wild. I also noticed that the engine RPM's gauge is not steady, and moves radically I have contacted my local dealer in the past with my concerns of a harsh shift issue, as well as the shuttering and luging down on the hills, and they assured me that they haven't had any issues with their transmission. These trucks need to be looked at very closely before someone has a catastrophic accident. I have an appointment on the 5 of December 2020, and you would think with the safety factor of my concerns, that they would try getting me in sooner, rather then put me off over two weeks.
This truck has so many issues first one was a fuel pump sending unit and it appears to be linked in with a lin data base? I had it repaired was good now it pops on again but its saying it can be something in the lin system sad todays cars are just filling up the junk yards and charging 50K for a new one its sadly piss poor quality
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.
Vehicles engine and ignition shut off while turning right. Engine can be restarted immediately. This has occurred 3 times in 3 weeks (1090 miles) unexpectedly while traveling at low speed. One time while entering a roadway from a parking lot, one time while pulling over to park and one time while turning off of a highway off ramp. The dealership, healey brothers of middletown, NY attempted to recreate the problem, but was unable to do so and has no answers as to what could be the problem.
