More thoughts. A breakdown is defined as one of two things: faulty workmanship or materials supplied by Kia, or a gradual reduction in operating performance as a result of normal wear and tear. To me, this is the difference between a warranty and a service contract. Many people, including me, have been interested in one of these policies because there are so many electronic and computer-related components in the car. I'm not really worried about *electrical* parts (things like motors and switches, which are listed). It's *electronic* parts (circuit boards, etc.) that are more concerning to me. Those are not specifically mentioned, and those are expensive repairs.
Let's suppose that one of the Telluride's driver assist technology features (e.g. Head Up Display or Lane Keeping Assistance) stops working correctly. If I'm still under warranty, the underlying reason doesn't really matter - Kia has to fix it regardless. But after warranty, with this contract, things are different. Normal wear and tear does not really apply to electronic components, so I'll have to prove that there was faulty workmanship or materials. I believe that "workmanship" generally refers to the manufacturing process. If it's a problem with the design, that's usually not part of workmanship. But if I have a flaky electronic issue, if may be difficult or impossible for me to prove exactly what the underlying cause is. Is it a materials issue or was it designed poorly? If a board fails, is that a *faulty* material or just a normal lifespan? Maybe the company will be honorable and not quibble over this sort of thing, but it does give me pause. If you read the Consumer Affairs reviews (like is in post 18 of this thread), there are both positive and negative comments associated with the company.
