A method, system and computer program product for assisting a user in handling a vehicle service issue. A profile is created by a navigation system that stores preferences of the user, such as vehicle and vehicle service preferences (e.g., tire brands). The navigation system polls the vehicle sensors in the automobile diagnostic system periodically to interpret a status. If there has been a change in the status of a sensor (e.g., change in tire pressure) and if the change represents a service issue to be addressed, then a service issue has been identified. The navigation system then determines a change in the route the vehicle is currently traveling to reach a service destination (e.g., Discount Tire® store) to address the service issue (e.g., low tire pressure) taking into consideration the user's preferences (user's profile specified the Discount Tire® chain to handle all service issues relating to tires).
