Would something like a "using unauthorized filters voids your warranty" agreement suffice? I can understand the manufacturer's desire to avoid costly repairs caused by shoddy aftermarket parts, but I don't understand the idea of rendering the end product totally unusable.
To put it another way, should my car stop running entirely if it detects that I'm using a "non-GM-certified" cabin air filter?
