Trailboss2021

2021 Trail Boss 6.2L v8. 21000. Same thing.. parking brake engaged Evs, shaking knocking and all kinds of lights. Had it towed in bc it was unable to be driven to the dealership couldn’t control the brakes or steering well. first thing they said it was injectors then dealership said pushrod bent due to lifter failure replaced 8 lifters number 7. It has been in the shop since June 1 went to pick up Friday within a few minutes struggling to get over 40mph and wouldn’t go over 60mph. Turned around and brought it back for the same issue. Service Manager stated a wire is loose and it will be ready Monday. Let’s see hope so. Brand new truck not even a year. Anyone got this fixed and any further issues ?
