THE CYLINDER HEAD BOLTS STRETCHED RESULTING IN OIL LEAK AND HEAD GASKET FAILURE. LEAK VARIES FROM DROPS ON GARAGE FLOOR TO SMOKING OIL CLOUD FROM ENGINE COMPARTMENT.

ENGINE HALF CASE OIL SEAL FAILED RESULTING IN LEAKAGE, POSSIBLE ENGINE FIRE HAZARD. *MJS
I UNDERSTAND FROM MY MECHANIC THAT THERE HAVE BEEN SEVERAL CASES OF CRACKED TRANSMISSION CASES, WHICH ARE VERY EXPENSIVE. I WOULD HAVE HOPED THAT CADILLAC WOULD PAY FOR THE PARTS TO REPAIR THIS REPAIR, SINCE IT COULD HAVE RESULTED IN A FATILITY. DO PEOPLE HAVE TO DIE BEFORE A SAFETY ISSUE LIKE THIS IS ACTED UPON? *AK
ENGINE IS MADE OF 2 METALS, THEY EXPAND DIFFERENTLY, OIL USAGE IN VEHICLE IS 3 QUARTS WEEKLY. CADILLAC DEALER MADE CONSUMER AWARE OF THIS FACT. *AK
OIL IS LEAKING FROM CRANK CASE, POSSIBLY CAUSING OTHER RELATED DAMAGE. *AK THE OIL LEAK IS DUE TO DESIGN FLAW, WHICH THE MANUFACTURER IS AWARE OF BUT RELACTANT TO REPAIR BEYOND WARRANTY. *YH
ENGINE OIL LEAKS, IN TWO PLACES, POSSIBLE HEAD BOLTS STRIPPED, GM RECOMMENDS REPLACEING ENGINE AT A COST OF $7,500. THE ENGINE HAS ONLY 72,500 MILES ON IT. THIS IS NOT ACCEPTABLE. GM SHOULD REPAIR THIS PROBLEM AT NO COST, DUE TO PROBLEM ORIGINATING FROM A DESIGN PROBLEM.*AK
ENGINE BOLCK THREADS FOR HEAD BOLTS FAILED, RESULTING IN BLOWN HEAD GASKETS AND LOSS OF ENGINE COOLANT, CAUSING ENGINE TO OVERHEAT.

OIL PAN IN THE NORTHSTAR ENGINS HAVE DEFECT THE MANUFACTURER IS AWARE OF AND WILL FIX IN ANY UNIT UNDER WARENTY OR EXTENDED INSURANCE PROGRAMS. THE PROBLEM IS A STRUCTURAL WEAKNESS OF THE CAST METAL OF THE OIL THE OIL PAN IS CONSTRUCTED....MINUTE CRACKS DEVELOP IN THE METAL AROUND THE RETAINING SCREWS OF THE OIL PAN AND EXCESSIVE SEEPAGE IS ENCOUNTERED CAUSING AT THE LEAST AN ENVIRONMENTAL HAZARD. OWNERS WITHOUT THE ABOVE COVERAGE ARE FORCED TO PAY EXTENSIVE REPAIR COSTS WHICH SHOULD BE BORN BY MANUFACTURER WHENEVER THE PROBLEM DEVELOPS. I HAVE A DEFINITE FEAR OR REPRECUSION AND DO NOT WANT MY IDENTY OR MY VEHICLE IDENTY MADE PUBLIC.
