I was at the dealership for four and a half hours for an oil change. I didn t get any updates from my service provider during my wait unless I hunted him down to ask for an update. I can understand if the service department if is overwhelmed with high volume or they are understaffed, but at least communicate that to me. I was initially quoted 90 minutes and I had an appointment. Pretty unacceptable...
