The only symptom was a high pitched squealing sound during very cold weather. The problem has been reproduced by the dealer. The problem first appeared the first winter owning the vehicle.

We are concerned about how safe our vehicle is when in "park". We will, on occasion, get a "Place in Park" message when the shifter is clearly in the park position. The dealership is not aware of any service bulletins or recalls, and since the problem is intermittent cannot offer a clear assessment.
