I just bought a 2020 rst Z71 6 days ago. Still on first tank of gas and truck went crazy this morning. Service ESC, brake light, engine light flashing, traction control light, ran really rough and shaky, on star email stating emissions system issue. Unbelievable!! I was very close to dealership so I brought it in immediately. Service writer looks up history and it was already in for a misfire in cylinder 8 but could not duplicate! This is a brand new truck! It had 100 miles on it when I bought it so I’m wondering if someone at the dealership was going to drive it but discovered it had a problem, had it looked at and they decided to just put it on the lot where unsuspecting me could buy it?! Seriously unbelievable. Can’t wait to hear what they say next week after they look at it...
