2000 Cadillac Deville engine and engine cooling problems

“DRIVING INTO MY DRIVE WAY I NOTICED THAT MY CAR PULLED IN VERY FAST. NORMALLY, I IDLE IN MY CAR INTO THE DRIVE WAY, THIS TIME IT WAS MUCH FASTER AND THE ENGINE WAS VERY ACCELERATED. I PARKED THE VEHICLE AND THE ENGINE WAS ACCELERATED UP TO 1850RPM. I PRESSED THE GAS PEDAL TO FREE UP THE THROTTLE, IT MADE IS WORST. THE VEHICLE RPM INCREASED UP TO 2835 RPM AND STAYED STUCK AT 2835 RPM. AFTER 10 TO 15 SECONDS THE RPM SLOWLY DROPPED DOWN TO 1500 RPM AND STAYED AT THESE REVOLUTION. I HAD TO TURN OFF THE VEHICLE. IT'S NORMAL IDLE RPM ARE 675-700RPM. THIS IS A SAFETY HAZARD FOR SOME ONE THAT DOES NOT KNOW WHAT TO DO WHEN DRIVING AT A BUSY HIGHWAY OR REGULAR CITY STREETS. *TR”

“TL* THE CONTACT OWNS A 2000 CADILLAC DEVILLE. THE CONTACT STATED WHILE DRIVING AT 25 MPH, THE ENGINE WOULD ABNORMALLY OVERHEAT. THE CONTACT RECEIVED A RADIATOR FLUSH AND THE WATER PUMP WAS REPLACED YET THE FAILURE PERSISTED. THE CONTACT STATED HE WOULD CONTINUOUSLY ADD ANTI-FREEZE TO THE ENGINE TO STOP IT FROM BECOMING EXCESSIVELY HOT. THE CONTACT TOOK THE VEHICLE TO A LOCAL MECHANIC WHERE IT WAS DISCOVERED THAT THERE WAS AN EIGHT INCH FRACTURE IN THE ENGINE BLOCK.

“"CHECK COOLANT" LIGHT, OVERHEATING, TAKEN TO GARAGE "FREE LANCE" CADILLAC MECHANIC RESEARCHED PROBLEM THAT IT IS A FACTORY RELATED INCIDENT THAT THE FIRST OWNER OF THE CAR IGNORED AND SHOULD HAVE BEEN SENT BACK TO GM AND THEY WOULD HAVE FIXED IT. I AM A SECOND OWNER TO CAR AND I HAVE "INHERITED" THIS PROBLEM. BLOWN HEAD GASKET............YOU POUR COOLANT IN AND IT RUNS RIGHT OUT THE TAIL PIPES! *TR”

CONSUMER WAS TOLD THAT THEY WERE POPULAR BY THE DEALER. *KB THE CONSUMER STATED THE ENGINE STALLED SEVERAL TIMES A MONTH BECAUSE OF THE CRANKSHAFT SENSOR. *JB”

“STARTED BURNING OIL AT 58,000. DEALER REPLACED PISTONS AND CHARGED ME $6376. CALLED MFG. TO COMPLAIN ABOUT COST. THEY IMMEDIATELY REFUNDED 50% OF BILL. WAS THERE A RECALL? AM I STILL PAYING MORE THAN I SHOULD? THE 50% REFUND CAME TOO EASY. I TALKED TO A STRANGER AT A CAR WASH, WITH AN IDENTICAL CAR, WHO HAD THE EXACT SAME PROBLEM! HIS WAS STILL UNDER WARRANTY. *NM”
