2002 Hyundai Santa Fe GLS. When moderately braking to slow down to exit the interstate the car rapidly decelerated and vibrated violently. Pulled over and could not get the car to go over 20 mph. My initial impression was that the transmission was failing. This happened randomly on several occasions. The 2nd time it occurred I had the car towed to the nearest Hyundai dealer. Dealer could find nothing wrong with the vehicle. I drove the car back without incident and dropped it off at the Hyundai dealer that sold me the car. They had the vehicle for several days before they could reproduce the problem. The diagnosis was a faulty brake system master cylinder and proportioning valve. Cost of the repair was over $500. I investigated this problem at various Hyundai forums on the internet and learned that this same problem has been reported on other Hyundai vehicles (including my generation of Santa Fe). I feel that any brake system failure is a serious safety defect that should be investigated.
