2006 Cadillac Sts recalls & complaints
Source: NHTSA, updated daily. Last checked 2026-10-18. Recalls apply to specific VINs — run your VIN to confirm.
4 safety recalls, most serious first
1. Fuel system
What's wrong, in plain English: Fuel lines, tank or pump. Fuel problems usually mean a leak, and leaks mean fire risk. In the affected vehicles, the electrical terminals of the fuel pump module may overheat resulting in the melting of the flange material.
What could happen: If the flange melts, a hole may be created allowing the fuel pump to leak fuel, causing the vehicle to stall, increasing the risk of a vehicle crash. Additionally, leaking fuel in the presence of an ignition source increases the risk of a fire.
The fix: GM will notify owners, and dealers will replace the fuel module and fuel tank jumper harness, free of charge. GM sent out interim notices in late October. The recall began on March 12, 2015. Owners may contact Cadillac customer service at 1-800-458-8006. GM's number for this recall is 14405.
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2006 STS.
- Book a repair at any authorized Cadillac dealer. Quote NHTSA campaign 14V542000 (manufacturer code 14405).
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-800-458-8006.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.

4. Fuel system
What's wrong, in plain English: Fuel lines, tank or pump. Fuel problems usually mean a leak, and leaks mean fire risk. 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.
What could happen: IF THE ENGINE STOPS RUNNING, THE OPERATOR WILL NOT BE ABLE TO RESTART THE VEHICLE WHICH COULD INCREASE THE RISK OF A CRASH.
The fix: 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.…

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 MA…

CERTAIN TIMES WHILE DRIVING, THE TRACTION ASSIST COMES ON, AND ALL POWER IS LOST TO THE ENGINE. LIGHTS ARE STILL ON, CAR IS STILL ON, BUT GAS DOES NOT ACCELERATE AND CAR IS HARD TO STEER. I HAVE HAD TO PULL OVER 6 TIMES IN THE LAST FEW MONTHS, TURN THE CAR OFF, RESTART AND HOPE IT DOES NOT HAPPEN AGAIN.
