Batteries in remotes go bad if you keep them too close to each other, good fuel mileage, hail damage all over, wear and tear on inside as well as outside of the car, automatic windows, child lock, remote start, heated seats, temp control on both sides of the car, all leather interior.

THE CAR RIDES REALLY WELL AND GAS MILEAGE IS OK, BUT THE A/C SPRUNG A LEAK AND IS NOT WORKING AT THIS TIME.

NICE LOOKING, LOVE THE COLOR AND THE CAR HANDLES NICELY. TOO EXPENSIVE TO REPAIR. THE DEALER WHERE I BOUGHT THE CAR USED NEVER BACKED UP SOME ISSUES THAT WHERE THERE FROM THE BEGINNING. SOME ANNOYING PROBLEMS THAT STILL EXIST AND NOW THE A/C HAS SPRUNG A LEAK.

To replace a headlight the entire front bumper and grill has to be removed also a tail light cannot be replaced the entire assembly has to be purchased at $1, 800 each also the service tire monitor light blinks constantly but the tire pressure is fine.

  • Air bags, dual-stage frontal and side-impact, driver and right-front passenger and head curtain side-impact, front and rear outboard seating positions with Passenger Sensing System (front passenger airbag status indicated on the inside rearview mirror) (Head curtain side air bags are designed to help reduce the risk of head and neck injuries to front and outboard rear seat occupants on the near side of certain side-impact collisions. Always use safety belts and the correct child restraints for your childs age and size. Even in vehicles equipped with air bags and the Passenger Sensing System, children are safer when properly secured in a rear seat.

Safety Recalls (1)

chevronDown icon
Exterior Lighting Mar 4, 2008
Report Receipt Date:
Mar 4, 2008
NHTSA Campaign:
08V108000
Summary:
GM IS RECALLING 4,586 MY 2008 CADILLAC STS AND STS-V PASSENGER VEHICLES FOR FAILING TO CONFORM TO THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 138, 'TIRE PRESSURE MONITORING SYSTEMS' (TPMS). THE STANDARD REQUIRES AN INDICATION TO THE DRIVER FOR CERTAIN TPMS MALFUNCTIONS. WHEN THE SYSTEM DETECTS A MALFUNCTION, THE LOW TIRE WARNING LIGHT SHOULD FLASH FOR ABOUT ONE MINUTE AND THEN STAY ON THE REMAINDER OF THE IGNITION CYCLE. A DRIVER INFORMATION CENTER MESSAGE WILL ALSO BE DISPLAYED ON THE INSTRUMENT PANEL.
Consequence:
THESE INDICATIONS OF A SYSTEM MALFUNCTION DO NOT WORK. PREMATURE TIRE FAILURE COULD RESULT IN A LOSS OF CONTROL OF THE VEHICLE, INCREASING THE RISK OF A CRASH.
Remedy:
DEALERS WILL REPROGRAM THE REMOTE CONTROL DOOR LOCK RECEIVER MODULE FREE OF CHARGE. THE RECALL IS EXPECTED TO BEGIN ON MARCH 18, 2008. OWNERS MAY CONTACT CADILLAC AT 1-800-982-2339 OR HTTP://WWW.CADILLAC.COM.
