Coolant Leaking Problems of Cadillac Deville

The contact owns a 1999 Cadillac Deville. While driving at an unknown speed the vehicle stalled. The dealer performed a diagnostic evaluation of the vehicle and located a coolant and water pump leak, as well as engine failure. There was pressure build-up and head gasket failure, which contributed to the failure. The dealer estimated that the repairs would cost over $3,000. Although there was a customer safety improvement campaign, the manufacturer denied the contact's claim due to the current mileage on the vehicle and because she was not the original owner. The current and failure mileages were less than 86,629. Updated 04/29/30.
