While taking a trip 750 miles from home, driving down the highway went over a overpass and lost power steering. The vehicle was hard to maneuver. There was no warning. It was a good thing there wasn't very much traffic as i was back and forth between the lanes trying to get the vehicle under control. We were stuck out in no mans land without cell service. We had to drive the vehicle 50+ miles to get to a shop. This was a Friday night and all mechanics have left for the day. The next morning we started car up and the steering wasn't as tight. But after awhile of driving it got harder to steer trying to find a shop to fix the problem. No luck. We had to drive it back home. That was the longest 750 miles of my life. We took it very slow coming home and keep switching driver as our arms got tired. Now working on trying to get it fixed.
