Electrical System Related Problems of the 2013 Nissan Titan

Alternator/generator/regulator problem

While on a road trip to tennessee, 1. 5 hours away from our destination we stopped at a gas station. We took the key out of the ignition of the truck and the truck kept running. All of the warning lights also came on at once. We could not turn the car off by disconnecting the battery because the alternator kept the car running. A check of the computer at an o'reilly auto parts did not show any computer warning codes. Since we did not want to be stranded 8 hours away from home, we decided to drive back home. While on the freeway, the truck's engine completely shut off. We had no power steering or power brakes. We were able to get it to the shoulder and restart the truck. While driving it off of the exit ramp, the truck died again. We tried going to another auto parts store but they were not able to get a code reading off of the car. A call to a Nissan dealership told us to just pull fuses to shut the car off and that they wouldn't be able to help us for 2 days. We disconnected the battery when the truck had died to try to reset the system and drove back on the highway. The truck died again. A call to the Nissan roadside assistance hotline told us we should just call 9-1-1. We realized that if we didn't drive the car faster than 60 mph we it would not shut off while driving so we were able to make it home. This incident could have killed us had my husband not been as skilled of a driver. Online research shows that other people have had the same issue with their Nissan Titans. This is an extremely serious issue and, when contacting Nissan about it, they do not care. Please help us.
