There must be an independent repair facility in Bend that has the ability to do this type of service work. I am sure that you have you researched that. I know that Klamath Falls has nothing. I can't even get Lithia to honor the warrantee work on my 2014 RAM 1500.
I prefer driving to Bend for shopping: Trader Joe's, Costco, Lowe's, good food and beer. It is fifteen miles further than Medford, but less fuel to get there and a pleasant drive, so I hope that other members read this and respond with their suggestions.
