2018 Chevrolet Silverado 1500 Fuel System Problems

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.

While driving my 2018 Silverado, the 5.4L, 327c.I. engine began idling very rough, shaking and periodically stalling. The check engine light began blinking and it threw codes PO308 & PO301.

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.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that on three separate occasions while driving at various speeds, the vehicle lost motive power and stalled without warning. The contact was able to restart the vehicle after the first failure and called the dealer; he was instructed to keep driving the vehicle and that there were no recalls on the vehicle.

There was fuel in the engine oil. Had to replace all of the injectors and the high pressure fuel pump. The shop I had it done at said this is known issue on these trucks - why isnt something being done?

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).

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.
