At about 60 speed on the highway, all engine lights came on and the engine turned off. The car steering wheel locks up. I pulled over to the shoulder and successfully restarted the car after about 10 attempts. The car started again and ran well for another 10 minutes. Again, at about 60 miles per hour, the engine halted and I had to change 3 lanes to get to a shoulder. The cars behind me were coming at full speed while my speed was going down fast. There seems to be a recall for this model year, make, and model, but Infiniti dealership is telling me that my VIN # is not included in the recall. I have seen many people online with the same exact problem.
