At 15 months, 13000 miles, the passenger door sill (the aluminum plate) sprung up. Front edge is up a couple of inches, and double stick pads won't hold it down. Took it in to the dealer, service manager said he had seen it several times, had just ordered a couple (warranty) and added mine to the order. He says they replace the whole sill (black plastic piece with the aluminum insert).

Just to alert that this is a warranty item.

 

Thanks for the heads up! I love this forum!
