What is NOT an essential detail to include in a vehicle repair order?

In the context of a vehicle repair order, the essential details serve to facilitate efficient service and effective communication between the customer and the service personnel. Repair part brand is not typically considered a critical piece of information to include in a repair order because it does not directly relate to the service or repair process for the customer in the same way that the other choices do.

Previous service history is vital as it provides insight into the vehicle's past repairs and maintenance, which can affect current diagnostics and recommendations. Customer's insurance details are important for processing claims or ensuring that repairs are covered under warranty or insurance. The vehicle's warranty status can impact the types of repairs performed and whether the costs are covered, making it essential for both the service advisor and the customer to understand. Thus, while knowing the repair part brand may aid the technician or influence decisions, it is not crucial for the creation of the repair order itself.
