When I'm driving my vehicle in a city street I get an alert on the instrument panel which says "trac off - check awd system" and the service light turns on. I did not turn the trac off. When I turn the vehicle off and then back on, the service isn't on anymore and the message goes away. This has happened several times when I'm driving and the car stalls and loses speed and wants to shut off as I'm driving in a city street. For several minutes and the service light and the track and awd light turn on and stay on for several hours. However, when I turn off the car the lights are still on but go away after some time. This has happened several times.
