I have a 2010 wrangler with 3,000 miles on it. Saturday, the check engine light came on along with the ESP light and the Electronic Throttle Control light. Owners manual says to shut the vehicle off and restart. I did and the all lights went out except for the check engine light. Went to the dealership today and was told they couldn't read any codes because I had "reset" them by turning the vehicle off, which is what the owners manual says to do! It was all I could to keep the engine running and get powere to the wheels. I was told I would have to drive it until the lights come back on and then limp it to the dealership so they can analyze the codes!
I thought the computer stored every code as it came up. Am I wrong about that? Or am I just getting the run around from the service department?
