Report "Hi guys I have a Stelvio 2009 with only 3500 miles. Recently it developed a problem of not starting and showing a SERVIVE NEEDED light on the screen along with the red warning triangle on the upper left side. The problem comes and goes, it appears, then I take it o a shop and a few hours later it starts right up with no warning lights or problems. When it does not start the lights do not turn on with the ignition, only the parking lights turn on. I have accidentally overfilled the tank a couple of times and I do not know if this could be the cause with vapor lock damage. The problem however has not appeared when I have accidentally overfilled tank. Any clues?"
