2005 Nissan Pathfinder brakes problems

After having the transmission and radiator replaced twice (3/12 and 10/12) as I was driving 65 miles per hour on the highway, all lights on dashboard came on, car died. I had no power and somehow managed to get to the side of the highway slowing for the length between two exits until I could steer into guardrail to stop the vehicle. Car was smoking, coolant system mechanic thinks let go and engine cracked, nissan refuses to buy back car that was a lemon in the first place.

Tl*the contact owns a 2005 nissan pathfinder. The contact stated that while reversing out of her garage, the brakes failed and to stop she would have to pump the brakes. The vehicle was inspected by a dealer who informed the contact that they could not duplicate the failure. The vehicle had not been repaired. The failure mileage was approximately 69,000.
