2009 Cadillac Sts

WHEN DRIVING IN RAIN THE SMALLEST AMOUNT OF WATER WILL CAUSE THE REDUCED ENGINE POWER TO ENGAGE AND IT DOES NOT GO OFF UNTIL THE VEHICLE HAS SAT FOR A LONG AMOUNT OF TIME. EXTREMELY DANGEROUS. FIRST THE ABS LIGHT COMES ON AND THEN YOU LOSE POWER. 3RD ROW LED TAILLIGHT OUT... 400 TO FIX. PURCHASED IN MARCH OF 2018 WITH 93K MILES. CURRENTLY AT 104K.

THE CAR TRACTION CONTROL FAILED AND THE VEHICLE HAD THE SERVICE STABILITY SYSTEM COME ON. THE ABS LIGHT WAS LIT AND THE VEHICLE WOULD NOT ACCELERATE OR TURN EASILY. THE VEHICLE WENT INTO THE DITCH. THIS VEHICLE HAD HEADLIGHTS PRIOR TO THE INCIDENT WITH BULBS POPPING OUT INSIDE AND MOISTURE. AFTER THE REPAIRS WERE DONE BY THE BODY SHOP THE NEW HEADLIGHTS HAVE HAD THAT SAME PROBLEM. THE AIRBAGS NEVER CAME OUT, AND THERE IS A MESSAGE DISPLAYED INDICATING THEY NEEDED SERVICE. IT WAS NEVER ADDRESSED BY THE BODY SHOP. ALSO PRIOR TO THE INCIDENT THE STEERING HAD AN ISSUE CAUSING PAIN TO MY SHOULDER. THE DIAGNOSIS WAS WRONG AFTER THE STEERING SERVICE LIGHT REMAINED AFTER A GEAR REPLACEMENT AND THE SAME ISSUE CAUSED PAIN. TIME PASSED AND THE SHOULDER GOT WORSE. THERE HAS BEEN 2 WHEEL SENSORS WITH ISSUES. THE DEALER NEVER TOLD ME THAT THERE WAS A SPECIAL WARRANTY FOR THE TIMING BELT WHEN I BOUGHT THE CAR. I AM ALSO NOW HAVING ISSUES WITH THE COMPUTER SCREEN. I CANNOT CHANGE THE TIME ANYMORE.

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 UNSAFE CONDITION WHEN A STABILITY SYSTEM ERROR IS DETECTED.

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.
