I will be be driving (speed is not a factor, happens at low speeds & high) the radio and navigator will cut out, then come back on (happens in a second or two). When it comes back on, all the warning lights come on. If I am traveling at a low speed, I can detect a sluggish acceleration but I don't notice this if I am on the highway. The only difference in driving if I am on a highway is that the cruise control (radar) is not available (I also suspect that some of the other features, like FOW are also not available). When I do come to a stop, I notice the sluggish acceleration at slower speeds. Once I have stopped, shut the car off and started it back up the warning lights disappear, except for the Check Engine light which persists for a while, then turns off maybe a day later. The cruise control is available when the car starts up.

I am taking the car in to the dealer, but I would like to know if anyone else has encountered this problem.
