How does the 10-yr warranty work? Are you required to have the car serviced at it scheduled times at the dealer or a service station. Can I decide to service it myself, under my shade tree, or will this void the warranty, even if I keep the receipts?

I believe that US law protects car buyers from strict service requirements.
The dealer/company cannot force you to have service at a specific place, unless you specifically sign a separate contract (like for the free BMW maintenance).

They’ve begun posting notices to this effect at the Jiffy Lubes, because of dealers’ unscrupulous practices.
