Noticed brown liquid leaking from the front driver wheel area. Had vehicle towed to gm dealer where they discovered a coolant line failure which created leaking of transmission fluid into radiator and coolant into transmission. Both transmission and radiator need replacing, car is unable to be driven. This was determined by the dealer and Cadillac to be a failure of the part, unable to be prevented and unable to detect. Consumer was not at all responsible for damage. Total estimated cost $4,900. Contacted gm where they offered to "split" the cost 50/50, myself reliable for the $2400. Although Cadillac took responsibility for the failure, I am responsible for the cost of repair.
