I've had my 2007 450GL for almost a year now. The check engine light has come on at least six to eight times, always requiring a visit to the car shop. Is this common? It's not always the same codes. This last time I was told to change the grade of gasoline. It's quite frustrating and expensive. Any suggestions?
