The high pressure fuel pump failed and sent metal particles throught the fuel system. All fuel components except for the injectors are available. The engine stalled while driving at speed forcing me to stop and call a tow truck on the side of the road. Mileage at failure was 81340. Preston hood Chevrolet diagnosed the HP4 failure and replaced the entire fuel system, noting metal contamination in all areas. The component has not been inspected. The truck had a slight grinding noise when shifting into 4th on throttle. Took it to a firestone and the techs noted its possibly just shifting hard, no issues found. The grinding noises ultimately was the HP4 failing. No warning lamps or other indications of a problem were present prior to the catastrophic failure.

Most recent owner complaints, unedited.
Recall N192265660 repair failed. Dealer stated that GM refused to participate in the repair. Smoke and smell of burning electrical followed by the rear window exploding. Dealer quoted over $1900 to repair and suggested we go aftermarket and have the repair done elsewhere. Vehicle has approximately 62k miles since last attempt to repair the recall.
I’ve heard all the horror stories about faulty electrical issues. I’m chasing an issue now on my 2018 with ONLY 87,000 miles after spending a bunch of money on batteries hub assemblies random control modules to try to fix an issue of stabilitrak, traction control, abs, trailer brakes, power steering etc all going off every 3 seconds. Grounds have all been re done to bare metal nothing is fixing the issue. Steering wheel about flew out of my hands going 65mph when the power steering message along with all the others on the dtc while dinging annoying the shit out of me. I’ve bought nothing but gm trucks my whole adult life and I’ll never do it again. Thing is a piece of shit and you all should be doing something to fix it. I’ve seen people have the fix by replacing a tail light bulb speed sensors ecbm abs modules trailer brake modules harnesses the list is endless. Someone is going to die when they crash from some bullshit electrical problem that can’t be chased down because it’s always something different. The money we pay for these trash trucks is insane for the problems like this that you won’t recall. That’s it these trucks suck and I’ll never buy another one. Trash.
