I have a brand new 2014 WRX with only about 500 miles on it and I have a problem that could be dangerous. The car will rev by it self as if you put your foot to the floor on the gas peddle, it does this while I am sitting at a stop when it is in gear idling with the clutch disengaged and my foot on the brakes. I shut the engine off and on restart it revs right up again. I does this for 4 0r 5 restarts then goes back to idle and runs perfectly normal. This has happened 5 times, 3 times in the first weekend I had the car. I have taken the car back to the dealer and the diagnostics are normal and no defects are shown. The dealer says they have never seen this problem before. They have had my car for over two weeks now and drive it occasionally with no problem showing up. The last I heard from them is they called Subaru about the problem. Has anyone ever heard of this problem happening.
