ENGINE
The known timing chain issue GM done a warranty for to fix it but won’t fix it now. My car is running sluggish because of it and had numerous times that it wouldn’t go up to the speed limit almost caused accidents because of it and I’m afraid to even drive it anymore knowing that it’s a time bomb waiting to happen that could blow up on the highway that can cause accidents.

POWER TRAIN, ELECTRICAL SYSTEM
The vehicle experiences a Shift-to-Park malfunction in which it does not consistently recognize that it is in Park, despite being physically shifted into the Park position. When this occurs, the vehicle may fail to shut down properly or behaves as if it is not securely in Park. The condition is reproducible and occurs during normal use. The issue first appeared in approximately mid-2024 at an estimated mileage of 80,000–85,000 miles and continues to occur. No crash or collision has occurred. However, the defect involves core powertrain and electrical systems and presents safety concerns related to reliable gear recognition and vehicle shutdown. The vehicle remains available for inspection upon request.

Dealership had ownership of car and should have replaced the timing chain before selling car to me, which they did not and after time for repairs to be done before time ran out, I had to pay for repairs, causing me be be out $3000+ dollars for repairs should have been covered by the warranty.

The steering wheel became uncontrollable while idle and can't turn the steering wheel without picking up speed. While stopped you can't turn the steering wheel, it's like trying to turn it while the engine is off.

ENGINE
The Cadillac Company sent me a letter several years ago informing me of a premature timing chain wear and the illumination of the Service Engine light. They knew about this defective engine problem but they did not recall the vehicle. Instead they extended the engine warranty to 10 years or 120,000 miles. I have only 90,000 miles on my vehicle but I've owned it for over 10 years and now the check engine light is illuminated. The Cadillac dealer refuses to extend the warranty. This is a safety issue because if the engine were to fail the driver would also lose power steering and power brakes putting the safety of the vehicle occupants and others at risk. I believe that this vehicle and other GM vehicles with the 3.6 liter engine should be recalled and repaired at no cost to the vehicle owner.

AIR BAGS, SEAT BELTS
THE SERVICE AIRBAG LIGHT IS NOW ON AND I NOTICE NUMEROUS OTHER COMPLAINTS FOR THIS VEHICLE INCLUDING INJURIES. CADILLAC DEALER SAYS THEY WISH TO CHARGE FOR DIAGNOSTICS AND BELIEVE IT IS A SEAT-BELT PRETENSIONER WHICH THEY WOULD NOT COVER. REPAIRS WOULD BE AS MUCH AS VEHICLE VALUE. I NOTICE A RECALL WAS ORDERED FOR VEHICLES ONE OR TWO YEARS NEWER WITH THE EXACT SAME ISSUE. WHY NOT EXTEND TO THIS YEARS SAME VEHICLE MODEL. *TR

ELECTRICAL SYSTEM
MY CAR HAS BEEN DIAGNOSED AS HAVING 'EXTENDED CRANK'. MY LOCAL CHEVY DEALER MADE APPROXIMATELY FIFTEEN ATTEMPTS AT FIXING IT TO NO AVAIL. I'M TOLD IT'S THE CHECK VALVE, BUT I HAVE NOT HAD THAT DONE BECAUSE ALL ATTEMPTS BY THE DEALER DIDN'T WORK; E.G., NEW COMPUTER (AND REMOVED), BATTERY (AND REMOVED), FUEL PUMP, ETC. VERY FRUSTRATING AND I FEEL IT'S A MATTER OF HEALTH AND SAFETY BECAUSE THE CAR ALMOST NEVER STARTS ON THE FIRST ATTEMPT, AND SOUNDS LIKE IT'S A DEAD BATTERY.

ELECTRONIC STABILITY CONTROL (ESC), ELECTRICAL SYSTEM, EXTERIOR LIGHTING
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.

MY AIRBAGS DID NOT DEPLOY AND MY TRACTION CONTROL FAILED. THE AIRBAG LIGHT REMAINS ON AND THERE IS A FAULTY CODE. THE VEHICLE LOST ABILITY TO CONTROL IT TO TURN. I WENT STRAIGHT INTO THE FENCE. THE AIRBAGS WERE NOT ADDRESSED BY THE BODY SHOP OR REPAIR SHOP.

AIR BAGS
I UNDERSTAND THAT 2006 CADILLAC CTS HAS A RECALL FOR AIRBAG PROBLEMS. CADILLAC DOESN'T DENY THAT THE SAME SYSTEM WAS USED IN THE STS. I'VE SEEN SEVERAL COMPLAINTS ABOUT THE SAME PROBLEM. I JUST WONDER WHY THE STS WAS NOT RECALLED. I KNEW THERE WAS NO WARRANTY, AND THAT'S WHY I CONTACTED CADILLAC. KNOWING THIS THEY SENT ME FOR A DIAGNOSTIC, WHICH WAS A WASTE OF TIME AND MONEY. THE END RESULT WAS THAT THEY SAID IT'S NOT UNDER WARRANTY. I WOULD JUST LIKE YOU TO INVESTIGATE TO SEE IF THERE SHOULD BE A RECALL. THIS IS A SAFETY ISSUE THAT CADILLAC SHOULD ADDRESS. *JS

AIR BAGS, ELECTRONIC STABILITY CONTROL (ESC), STEERING
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.
