NHTSA lists 2 safety recalls and 53 owner complaints for the 2007 Cadillac STS. Most complaints involve air bags (16) and electrical system (11). The EPA rates it 16–19 mpg combined.
General Motors LLC (GM) is recalling certain model year 2004-2007 Cadillac CTS-V vehicles manufactured October 6, 2003, to March 15, 2007, and 2006-2007 Cadillac STS-V vehicles manufactured June 23, 2005, to March 15, 2007. In the affected vehicles, the electrical terminals of the fuel pump module may overheat resulting in the melting of the flange material.
ON CERTAIN PASSENGER VEHICLES, THE REAR AXLE PINION SEAL DOES NOT MEET ALL OF THE SPECIFICATIONS AND MAY EXPERIENCE A FLUID LEAK.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“Air bag on the steering wheel has oozing glue that oozed/leaked out of the airbag and has hardened on outer cover! Lights and radio don’t disconnect or turn off when car is turned off and drain battery.”
“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.”
“I NOTICED THE GEAR SHIFTER LOCKED IN PLACED WHERE ONE CAN NOT MOVE THE UNIT FROM PARK TO DRIVE; I RECEIVE THE SHIFT TO PARK MESSAGE ON THE VIC VISUAL INFORMATION CENTER. I BELIEVED THERE WAS A RECALL ON THE SAME CAR IN THE 2006 CADILLAC STS; THE SHIFT TO PARK ERROR MESSAGE ALSO COMES ON AFTER DRIVING AND UNABLE TO TURN THE UNIT OFF (RED LIGHTS OF COURSE) UNTIL THE BATTERY DIES. NO RECALL”
