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.
