Called to make an appointment just now because the wrench light is on. The line was busy so I was put on hold and transferred to a technician. To my surprise, after he inquired about the vehicle info, he told me that the light only indicate for oil change and there is no need to maintenance unless I want one. The other two auto shops I called said they will need around 1.5 - 2 hrs and follow Scion's maintenance guidelines. I want to sincerely thank the staff for the expertise and the honesty. I will definitely come back if I ever need auto service.
