For instance, it would be wise to put an end to hauling a trailer. Get the car evaluated as soon as you can to avoid costly damage.
- If any built-in diagnostic tools are available, use them. Many contemporary vehicles feature built-in remote diagnostic capabilities that allow for reporting on fault codes and scheduling an appointment for service. Today, numerous automakers offer remote diagnostics and the option to book a service appointment, including Fiat Chrysler, Ford, Hyundai, Jaguar/Land Rover, and Volvo.
