They haven’t… We have numerous 200K+ examples ruling the highways with original turbos, some of whom have towed most of their lives.

So it’s only natural that we think a belt is a point of failure, especially with the history timing belts have developed over the years. A couple important differences, though… These are “wet” belts cooled and lubricated by engine oil, and there is no service interval. Traditional timing belts almost never fail before their maintenance interval, and these are clearly designed to last for the life of the engine. I’ve stopped assuming I know more than the engineers who designed them, and refuse to worry about something until I have reason to. And unless they start breaking, there’s just nothing to see here, folks.

I'll be very surprised if it says you must get all oil changes at the dealer. In fact, I think it would be illegal. Sure sounds like your dealer is just trying to screw you and recoup the costs of the "free" warranty.

I got a lifetime powertrain warranty from my dealer also. It's from a third party, as they always are (I have never heard of a dealer having their own lifetime warranty in-house). The fine print definitely does not say oil changes must be done at the dealer. It does say that I must follow the maintenance schedule and provide documentation as proof in the event I submit a warranty claim. It also says my deductible is $200 if I have the warranty work done at the selling dealer. Otherwise it's $500 at any other dealer.
