Scheduling Service Appointments (U.S. and Canada)
When the vehicle requires warranty service, contact your dealer and request an appointment. By scheduling a service appointment and advising the service consultant of your transportation needs, your dealer can help minimize your inconvenience.
If the vehicle cannot be scheduled into the service department immediately, keep driving it until it can be scheduled for service, unless, of course, the problem is safety related. If it is, please call your dealership, let them know this, and ask for instructions.
If your dealer requests you to bring the vehicle for service, you are urged to do so as early in the work day as possible to allow for same day-repair.
