Around 69K miles I started getting the classic rumble/vibration from the rear passenger side wheel. Car is under extended warranty, so I took it to the dealer, as the warranty says that front and rear wheel bearings are covered. Diagnosis was that the bearings needed replacing, but could only be done with a new hub assembly, which had a part number NOT covered under warranty. So I owe the $150 diagnosis fee (kinda like gambling to see if a repair is covered) as well as the cost of the repair - close to $400 in total. Wouldn't have asked to check for warranty coverage if the literature didn't mislead me...
