6 reports
“TL* THE CONTACT OWNS A 1999 CADILLAC ELDORADO. THE CONTACT STATED WHILE DRIVING AT ANY SPEED THE BRAKES ENGAGED ON THEIR OWN AND CAUSED THE VEHICLE TO COME TO A COMPLETE STOP. THE STABILIZER CONTROL LIGHT ILLUMINATED WHEN THE FAILURE OCCURRED. THE VEHICLE WAS TAKEN TO THE DEALER WHO PERFORMED A DIAGNOSTIC TEST THAT LOCATED THE FAILURE WITHIN THE STEERING SENSOR MODULE. THE DEALER REPLACED THE STEERING SENSOR MODULE, BUT THE FAILURE WAS NOT REPAIRED. THE DEALER TEST DROVE THE VEHICLE, AND WAS UNABLE TO DUPLICATE THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 23,000. THE CURRENT MILEAGE WAS 26,000.”

“TL* THE CONTACT OWNS A 1999 CADILLAC ELDORADO. WHILE DRIVING 55 MPH, THE VEHICLE STARTED TO OVERHEAT. THE VEHICLE WAS TAKEN TO THE DEALER WHO PERFORMED A DIAGNOSTIC TEST AND FOUND THAT THE WATER PUMP AND THE OVER PIPE GASKET WERE LEAKING. THEY REPLACED THE WATER PUMP, THE OVER PIPE GASKET AND THE THERMOSTAT BUT THE FAILURE CONTINUED TO RECUR. THE VEHICLE WAS TAKEN BACK TO THE DEALER WHO STATED THEY WERE UNABLE TO FIND THE PROBLEM FOR THE FAILURE AND TO TAKE THE VEHICLE TO ANOTHER MECHANIC TO GET A SECOND OPINION. THE MANUFACTURER WAS NOTIFIED WHO OFFERED NO ASSISTANCE. THE FAILURE MILEAGE WAS 184,320.”

“MY WIFE PURCHASED A 1999 CADILLAC ELDORADO IN 2009 AND IT ONLY HAD 38K MILES ON IT. NOW IN 2016 IT ONLY HAS 103K MILES ON IT BUT WHILE DRIVING THE ENGINE COOLANT TEMPERATURE GAUGE WILL FREQUENTLY GO FROM 'NORMAL' TO 'ENGINE HOT - A/C OFF'. AFTER SHUTING OFF THE ENGINE, LETTING IT COOL, AND TOPPING OFF THE COOLANT LEVEL, THE WILL OPERATE IN THE 'NORMAL' TEMPERATURE RANGE FOR SEVERAL MILES BUT THEN IT WILL SUDDENLY JUMP UP TO THE 'ENGINE HOT - A/C OFF' RANGE. THE CAR IS NOW AT A REPAIR SHOP AND THEY HAVE DIAGNOSED THAT THIS 1999 CADILLAC ELDORADO HAS FAILING CYLINDER HEAD GASKETS. RECALL - CAMPAIGN #99086 (MARCH 19, 2002) ACKNOWLEDGES THIS DEFECT AND THE REASONS FOR IT. WILL CADILLAC PLEASE HELP US WITH THIS PROBLEM? A 103,000 MILE CADILLAC ELDORADO SHOULD NOT HAVE THIS ISSUE AND, IF IT DOES, THE MANUFACTURER SHOULD TAKE RESPONSIBILITY.”
