The official notice
Defect
On certain vehicles equipped with a 2.8L V6 5-valve engine and automatic transmission, while driving for a considerable period of time at a steady rate of speed during extremely low ambient temperatures (-15 degrees Celsius or below), the throttle may not return to idle position due to ice accumulating in the throttle body. In this instance the driver can apply additional brake force or take other actions (such as shifting into Neutral, turning off the ignition, etc.) to positively stop the vehicle. In the absence of such action, the vehicle may maintain speed when the driver expects the vehicle to slow. If this occurs, it could lead to an increase in the stopping distance and possible collision with bystanders, a fixed object or another vehicle which may cause serious injuries or even death.
Safety Risk

Remedy
Dealers will replace the throttle body assembly.
