I woke up Saturday morning to head to work and the car would not go faster than 23 miles per hour. I called Nissan and had it towed to the shop right away. Shop called several hours later and said the car is fine and they could not find anything wrong. They drove it several times and it did not happen to them. So I picked up the car Saturday after work. I drove the car Sunday with no problems or issues. I went to work today -Monday and after work had a dental appointment, when I left the dental office once again the car would not go faster than 23 miles per hour. I immediately took it back to the Nissan dealership and requested they drive it in front of me and they did. They now have seen it is performing. They gave me a loaner car to drive so they can further diagnose and repair. Up until this point my Versa had been completely free of problems. I want my car to be all better.
