Diamante 6-cyl

  • Automatic transmission
  • miles
Heater core (and possible effect on transmission issues) going up before its time (and this known to be a problem on the Diamantes for over 3 years of the model) and causing antifreeze fumes and smoke to fill my car for months unnoticed exposing my family and self to nauseousness, headaches, not to mention expense of repair on a relatively new vehicle.
