Consumer Description

Traction control light came on and the vehicle felt like it was going to die/low idle. I took to dealership on 9/13/22 (5months after getting vehicle) and the codes P03000 00 which is an engine misfire, P050D 00 which is cold start rough idle and it was noted by service tech that engine making a clunk and ticking noise. There was a misfire on cylinder 6. They removed the valve cover and the intake valve rocker arm was not moving at all and when the rocker arm was removed they noticed the push rod was also bent. They verified the DFM lifter was collapsed.
