Front driver caliper overheated to 350+ degrees and dealership said it was a manufacturer defect. Now the driver rear caliper is doing the same exact thing and the dealership won't fix it, even though it is doing the same thing.
At these temperatures, the tire could catch on fire causing the tire to explode, but as of right now, Hyundai doesn't see a problem with this.
I encourage every 2007 Santa Fe owner to fill out a complaint with the National Highway Traffic Safety Association so they will open an investigation and issue a recall. The form takes about 3 minutes to do and can save all of us A LOT OF MONEY! They need only 5 complainants to open the investigation.

Um that's all well and good, but why don't you contact Hyundai consumer affairs before you do that, could save you time as well as money. Also take it to another dealer. I am truly amazed by the large number of people on this site turned off from Hyundai, not by the manufacturer, but by the large number of incompetent or dishonest dealers. I am senior technician for a Hyundai dealer and I don't have these problems, I am truly sorry for all of your unhappiness and disappointment in both you vehicles and the people you've had to do business with.
