While pulling this vehicle in to my garage about halfway in the brake pedal went to the floor and the vehicle hit a bench on the opposite side of the entrance. After pumping the brakes after waiting about 10 minutes they seemed to work normally. I backed the vehicle out of the garage and saw NO fluid under the vehicle. The next morning the vehicle was towed the the dealer collision shop and then taken to the service department at the dealer. This problem; ,after almost 2 months was never solved....corporate offices checked the data recorder...no conclusions.....and implied this problem did not occur. The body is now being repaired yet no brake problem has been ever repaired. ( under warranty....31,967 miles ). I understand a similar problem occured in New Jersey although on the road and the driver had to be removed through the sunroof and the vehicle was totaled.
