What must be provided in writing when using Nonoriginal Equipment Manufacturer (Non-OEM) aftermarket parts in vehicle repairs?

When using Nonoriginal Equipment Manufacturer (Non-OEM) aftermarket parts in vehicle repairs, obtaining the consumer's consent in writing is essential for several reasons. First, it ensures that the vehicle owner is fully aware that the repairs will involve parts that are not manufactured by the original equipment provider. This transparency helps the consumer make an informed decision regarding their vehicle's repair.

Additionally, consumer consent protects the repair facility by documenting that the customer agreed to the use of these aftermarket parts, safeguarding against potential disputes related to the quality, performance, and warranty of those parts. This practice can also help maintain trust between the repair facility and the consumer, as it underlines a commitment to communication and customer service.

The other options pertain to different aspects of vehicle repair documentation but do not address the critical need for consumer consent regarding the use of Non-OEM parts specifically. While warranty information and the repair facility's license may be relevant in various contexts, they do not replace the necessity of obtaining explicit consent from the consumer when introducing aftermarket components into repairs.
