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.

GM has produced millions of vehicles with the 5.3 motor with AFM, DOD, VVT issues. They are well aware of this issue. The factory defect causes the lifters to collapse causing catastrophic engine failure. This posses a hazard to consumers in traffic trying to navigate their stalled vehicles off the roadways. GM customer service is rude and dismissive, furthermore they offer no assistance to fix these problems. The issues with these motors is well documented and any repair shop/ dealership can confirm these issues. There is no indication from warning systems prior to this failure. However there are multiple Dash warning lights after the catastrophic failure occurs. The cost is passed to consumers to address these issues.

Upon light acceleration of the vehicle, a rough gearshift occurred followed by a check engine light and the vehicle continued to shift roughly and idled roughly. After months of diagnostic work and attempts at repairs, it was determined the lifters were the issue. From independent research I understand this is a somewhat common (and pricey) issue. I-??m not sure why there is not a recall for the cheap lifters, but I would like to pursue possible reparations for this fault of GM that has left me without a vehicle and left me with a great financial burden for over six months.

UNKNOWN The ignition, steering wheel, and electrical. While driving it flickers off and on, turns off the engine, unlocks my doors and turns on again. Yes, our safety as well as others are put at risk this can cause an accident to happen on the road while driving, most likely to get rear ended. Today it gave me a scare because my 2 year old granddaughter was in the truck.

During the mornings when first starting my truck, I get a stutter or hesitation to the engine when accelerating out of my driveway. This happens just about every morning. I have determined that the truck has to be off for about 10+ hours. The stutter/hesitation goes away after the car warms up in about 1 mile. Have had the truck into the shop but they can find NO problems.

Silverado 1500

Our 2018 Chevrolet Silverado 1500 was purchased new and only serviced at Chevrolet dealerships. While on vacation we were driving on a 3-lane paved road and then engine started knocking for a few seconds and then a chime could be heard and the check engine light came on. The vehicle lost power and the vehicle was difficult to control. We were fortunate that other vehicles were able to avoid us since our truck slowed quickly (without the brakes being applied). The vehicle had to be towed to a local Chevrolet dealer for diagnostics. The dealer found that the hydraulic lifters on the right bank of the engine collapsed (resulting in a misfire) and there was extensive engine damage. The vehicle was equipped with a 5.3l engine with AFM/DFM (cylinder deactivation). Mileage was 64,562. Vehicle was repaired with "upgraded" valve train parts from General Motors as this failure mode seems to be somewhat common in AFM/DFM engines (can find class action information during web search).
