Subaru is warning dealers about making modifications to their cars, listing simple items like changing tires and wheels, they also mention adding larger tires and wheels and lifting the vehicles, but they specifically mention changing tires and wheels.
Subaru is requiring that dealers must identify and document any changes they detect because it could impact warranty coverage. If a dealer does make non-standard modifications they must indemnify Subaru.
I think I'm going to have a discussion with my Subaru dealer and get a copy of their warranty support and manufacturer indemnification letter when they replaced my tires with non OEM tires. I replaced the OEM tires with the same size tires, but they aren't OEM and they could impact vehicle performance and I need to know that my dealer will stand behind the change.
With all the technology on cars it's looking like the car industry is going down the Apple/John Deer business model. You don't really "own" the car, you just pay to use it, and maintain it, but you don't own it.
