Exact make, model and year evidence from official US sources. Recall campaigns, ODI investigations, complaint allegations and EPA estimates remain separate.
A campaign may cover only certain production dates, plants or equipment. A zero result here is not safety clearance. Use NHTSA’s official VIN tool for the individual vehicle.
Exact model-level NHTSA results for 2005 CADILLAC STS. Campaign records are official safety actions; applicability to a particular car still requires its VIN.
ON CERTAIN PASSENGER VEHICLES, THE REAR AXLE PINION SEAL DOES NOT MEET ALL OF THE SPECIFICATIONS AND MAY EXPERIENCE A FLUID LEAK.
Consequence
A REAR DIFFERENTIAL FAILURE MAY CAUSE LOSS OF MOTIVE POWER AND POSSIBLY LOSS OF CONTROL INCREASING THE RISK OF A CRASH.
Remedy
DEALERS WILL REPLACE THE PINION SEAL FREE OF CHARGE. THE RECALL BEGAN ON FEBRUARY 1, 2008. OWNERS MAY CONTACT CADILLAC AT 1-800-458-8006 OR HTTP://WWW.CADILLAC.COM; PONTIAC AT 1-800-620-7668 OR HTTP://WWW.PONTIAC.COM; AND SATURN AT 1-800-972-8876 OR HTTP://WWW.SATURN.COM.
CERTAIN VEHICLES EQUIPPED WITH V6 ENGINES MAY HAVE A CONDITION WHERE FUEL IS NO LONGER SUPPLIED TO THE ENGINE. THIS CONDITION OCCURS WITHOUT THE ILLUMINATION OF THE FUEL LEVEL LOW INDICATOR LIGHT OR THE WARNING CHIME.
Consequence
IF THE ENGINE STOPS RUNNING, THE OPERATOR WILL NOT BE ABLE TO RESTART THE VEHICLE WHICH COULD INCREASE THE RISK OF A CRASH.
Remedy
DEALERS WILL REPROGRAM THE ELECTRONIC CONTROL MODULE (ECM) WITH NEW SOFTWARE FREE OF CHARGE. OWNERS WERE NOTIFIED IN DECEMBER 2005 AND ASKED TO MAINTAIN AT LEAST 1/4 OF A TANK FUEL LEVEL TO AVOID THIS CONDITION UNTIL THE PARTS ARE AVAILABLE. THE PARTS ARE NOW AVAILABLE, OWNER RENOTIFICATION BEGAN ON MARCH 23, 2006. OWNERS MAY CONTACT CADILLAC AT 1-866-982-2339.
CERTAIN VEHICLES HAVE A LEFT OR RIGHT REAR SUSPENSION TOE LINK THAT COULD SEPARATE BECAUSE OF AN INCORRECT WELD.
Consequence
IF THIS WERE TO OCCUR, THE AFFECTED REAR WHEEL WOULD BE ABLE TO TURN IN OR OUT, AFFECTING VEHICLE CONTROL, WHICH COULD RESULT IN A CRASH.
Remedy
DEALERS WILL INSPECT THE RIGHT AND LEFT TOE LINK AND REPLACE AS REQUIRED. IF A TOE LINK IS REPLACED, THE DEALER WILL PERFORM A WHEEL ALIGNMENT. THE RECALL BEGAN ON MAY 3, 2006. OWNERS MAY CONTACT CADILLAC AT 1-866-982-2339.

Complaints across nearby Cadillac STS model years
Totals for the same nameplate, scaled against its highest year here. They are not adjusted for how many were sold, how old they are, how far they are driven, or how much publicity a fault received — an older or better-selling year will usually carry more reports. This shows where the reporting sits, not which year is better.
An investigation means ODI reviewed a possible safety issue for this exact model-year identity. Opening one is not a defect finding; closing one does not by itself clear a vehicle.
