The truck's engine died while traveling down the highway around 60 mph. I lost all power and struggled to pull to the side of the road avoiding traffic. there were no warning lights or engine lights before the truck died. There was only a slight vibration and loss of power. Once I stopped on the side of the road smoke started coming out from under the hood. The truck has been maintained well and taken care of and has 59,000 miles on it. I was told by a Nissan mechanic that the motor is locked up because of a broken crank, and they are still trying to see what happened with the electrical wiring that caused the fire. The truck is out of warranty and they informed me that a new motor would cost upwards of $25,000 dollars.
