 We purchased our Five Hundred in July 06 with 6000 miles. On our first trip I noticed a bad vibration during braking going down hills. I contacted the dealer and they said that a factory brake kit was needed to fix the problem. The kit consisted of new discs and pads. Now after approximately 16,000 miles after the replacement, the rear brake pads were shot and needed to be replaced for $200. I contacted Ford and they will not admit that there is a problem with the brake design. I've also had to have the gauge cluster replaced. I thought Ford finally had a "Better Idea". I guess I was wrong.
