I'm going by what my wife described and what I observed afterward, but have no idea what happened. My wife started up her CX-9 to leave the house. The engine was cold but it was probably in the 70's here. She said she heard a loud tapping/knocking under the engine and when she looked in the rear view mirror she saw a lot of what she described as whitish smoke. No engine lights though and she turned it off. I came out about a half hour later it was smelling of gas so I had her start it up. I didn't hear any tapping or knocking and it was smoking out of the exhaust slightly but I couldn't tell if it was just moisture form being cold. The smell of gas and like something burning was very strong. As she said she saw white smoke and heard a knocking, I'm thinking Head gasket so I had it towed to the dealer. They called me today and said they could find nothing wrong. No engine codes, nothing. I went and picked it up and drove it home and it runs great.
My wife swears it was knocking loud and her rear view was full of smoke. She said she never touched the gas and cranked it like always. It has 125,000 miles on it but has never given us a problem. So while it runs great now, I'm having some trust concerns with the car as my wife takes my daughter to a lot of doctor appointments. I would feel much better if I could get an idea what happened and if its something I need to worry about. Anyone have this happen before or have any idea what it could be?
Thanks for any insight.
