NHTSA Complaint #10391428 — 1996 CADILLAC SEVILLE

GM HAS A KNOWN PROBLEM WITH THE CADALLIC NORTHSTAR 4.6L HEAD GASKETS. THEY BROKE DOWN BETWEEN 70,000 AND 140,000 MILES GM WILL NOT ASSIST IN THE REPAIR OF THE HEAD GASKETS. OUR CADILLAC IS A 1996 WITH 72,000 MILES AND HAS HAD THE LEAKING SINCE 40,000 MILES. THE DEALER WAS AND IS WILLING TO REPAIR FOR APPROX. $3500.00. WE HAVE NEVER BEEN TOLD ABOUT THE LAWSUIT THAT WAS FILES AND THE DEALER HAS KNOWN ABOUT THE DEX COOLANT PROBLEM. THE DEALER WILL NOT GUARANTEE THE HEAD GASKET THEY SAID WAS NEEDED . I DID NOT KNOW THAT THERE WERE SERVICE BULLITTINS ON PUTTING INSERTS IN THE BLOCK FOR THE HEAD BOLTS. I THINK OVER 50% OF THESE ENGINES HAVE HAD THE GASKET REPLACED. THIS WAS A PROBLEM, BUT I KNOW THAT THEY LIKE THE MONEY THAT IT BRINGS IN TO THEM.
