2005 Nissan Frontier electrical system problems

While driving down the road at 40MPH my frontier suddenly cut off , had no brakes or power steering. I went off the road and hit some trees. My insurance fixed my truck, even after I told them and the body shop I wanted it checked out first. I took it to the dealership and was told there was a recall with a defective ECM relay. They also informed me my radiator and transmission had a problem with the coolant leaking into the transmission.

Tl*the contact owns a 2005 nissan frontier. When she attempted to start the vehicle it would not start. After several attempts, she waited a few minutes and she was able to start the vehicle. The failure recurred intermittently. The vehicle was taken to an independent mechanic where they were unable to diagnose the failure. The manufacturer was notified and informed her that the vehicle was not included in any related recalls. The vehicle was not repaired. The failure continued to recur intermittently.
