My truck had been randomly misfiring but the dealership couldn-??t resolve the issue because the check engine light would go away on the way there. They were able to pull codes showing a misfire taking place and told me to return if it continued. The truck started having misfire issues again periodically fir the next 2 weeks but once the check engine light stayed on I scheduled an appointment. On the way to the appointment to Hidiburg Chevrolet we were on the interstate the cruise control kicked off, the service parking brake indicator, misfire flashing of check engine light, an ESC warning, and the traction control light came on as the truck randomly pulled to the right real quick then it stopped. Once the indicators went off all warning indicators were off and cruise control would not work. The dealership pulled codes and saw every cylinder misfired and that the other issues that took place. They tested everything and could not find the source and said that they had to wait until the indicator stayed on so they could see the issue. I left with no resolution and concern that when the misfiring could damage parts and the computer. I also fear that the issue if someone isn-??t aware of vehicles not fixed could lead to severe accidents and potential for death if not fixed.

I was stopped N the drive thru at in-N-out with my foot on the brake and the eco system had turned off the motor. It spontaneously turned back on without me lifting my foot off of the brake and the transmission engaged and the truck launched forward approximately 12-18 inches. This is the second time this has happened to me. It also happened one night about 2 months ago. This could have been very dangerous, I could have hit someone or their car or I could have even received whiplash myself.
