2009 Cadillac STS Complaints

TAKATA RECALL. PASSENGER SEAT, PASSENGER DETECT SENSOR (PPS) STOPPED WORKING. NO PHYSICAL DAMAGE. PASSENGER PRESENT LIGHT SAYS, PASSENGER AIR BAG OFF. AIR BAG DASH LIGHT ALWAYS ON. I CHECKED WIRING UNDER THE SEAT AND CAN NOT VISUALLY SEE ANY DAMAGE TO THE WIRING GOING TO THE SEAT CUSHION SENSOR OR THE SEAT BUCKLE SENSOR.

TL* THE CONTACT OWNS A 2009 CADILLAC STS. WHILE DRIVING VARIOUS SPEEDS, THE VEHICLE WOULD DECELERATE INDEPENDENTLY AND THE STABILITY SYSTEM WARNING INDICATOR ILLUMINATED. THE CONTACT COASTED OVER TO THE SIDE OF THE ROAD AND WAITED A FEW MINUTES BEFORE RESUMING DRIVING. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 140,000.

VEHICLE DETECTS FAULT AND DISPLAYS MESSAGE TO SERVICE STABILITY CONTROL SYSTEM. SPECIFIC PROBLEM NOT YET DIAGNOSED. WITHIN A FEW MOMENTS, THE DISPLAY STATES THAT ENGINE POWER IS REDUCED. THIS CAUSES A VERY UNSAFE CONDITION AS THE VEHICLE SLOWS TO 10-15 MPH. PRESSING GAS PEDAL CAUSES TRANSMISSION TO DOWNSHIFT TO LOWER GEAR SLOWING VEHICLE FURTHER. CANNOT SAFELY MANEUVER IN TRAFFIC, BRAKES REQUIRE MUCH HIGHER PEDAL PRESSURE DUE TO LOW VACUUM BOOST AFTER ENGINE POWER REDUCED. INSUFFICIENT WARNING THAT THIS IS HAPPENING. PROBLEM IS NOT WITH ENGINE OR POWERTRAIN, BUT ENGINE POWER IS CUT (ENGINE RUNS VERY ROUGH AS A RESULT) IN RESPONSE TO DETECTED STABILITY SYSTEM ERROR. ENGINE RUNS FINE IF TURNED OFF AND RESTARTED. NO OVERHEATING, OIL LEVEL IS FINE, GASOLINE IS GOOD, NO EXTERNAL PROBLEMS. AFTER RESTARTING CAR DRIVES FINE INITIALLY, EVENT RECURS WITHIN 1 MILE. VERY DIFFICULT TO TRY TO JUSTIFY THIS KIND OF INTENTIONAL VEHICLE CONTROL BEHAVIOR. EXTREMELY POOR DESIGN THAT CAUSES AN...

I PURCHASED A 2009 STS IN AUGUST OF 2014. I AM HAVING A PROBLEM WITH THE WHEEL BEARING HUBS GOING BAD. I HAVE REPLACED BOTH FRONT. THE FRONT LEFT SIDE HAS BEEN CHANGED TWICE IN A 13 MONTH PERIOD. UNFORTUNATELY THE PART ONLY HAS A 1 YEAR WARRANTY. I'VE ALSO HAD THE RIGHT REAR CHANGED IN MAY OF 2015 AND NOW IT'S JUNE 2016 AND HAS GONE BAD. I HAVE NO EXTENDED WARRANTY,I'M JUST CURIOUS WHY THIS PARTICULAR PART WENT BAD IN THE TIME FRAME THAT IT DID? I CALLED THE SALESMAN AT THE DEALER ABOUT THE FIRST INCIDENT TO SEE IF HE COULD DO SOMETHING TO HELP WITH THE REPAIR SINCE IT WAS ABOUT 6 MONTHS AFTER I PURCHASED THE CAR. I ACTUALLY BOUGHT IT AT THOMSON AND MCCONNELL CADILLAC IN CINCINNATI, OHIO, OF COURSE HE TOLD ME THAT HE WISHED THERE WAS SOMETHING HE COULD DO. I WON'T GO THERE AGAIN. I HAVE ABOUT OR CLOSE TO 90,000 MILES ON IT AT THIS TIME. I HAVE NEVER HAD TO HAVE THIS TYPE OF REPAIR ON ANY VEHICLE IN MY LIFE. MY PREVIOUS VEHICLE WAS A 2006 ESCALADE PLATINUM AND THE ONLY MAJOR THING THAT...

STARTED CAR TO PULL OUT OF GARAGE AIRBAG LIGHT CAME ON. TOOK TO DEALER WHO SAID AIRBAGS ARE DISABLED AND NEW MODULE NEEDS CHANGING AT COST OF $900.00.
