What 2007 Cadillac STS owners say
Air bags
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.
Passenger air bag warning light - dealer will not fix for less than $800.00. Same issue as 2007 Cadillac cts. See below. This was a company car built early for employee evaluation. I am sure it was the same seat system general motors is recalling certain model year 2005-2007 Cadillac cts vehicles. Some of these vehicles have a condition in which repeated flexing of the passenger sensing system mat in the front passenger seat May cause the mat to kink, bend, or fold. This flexing can break the connections in the mat. If this occurs, the sensor May not detect the presence of a front seat passenger and will disable the air bag.
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.

Stability & traction control
I was leaving greenville, s.c.and the left side brakes lock and pulled me into the left lane of traffic and I took my foot off the gas and the car free rolled for a short distance while I got back in my lane. I reapplied the gas and got back up to twenty-five MPH and the right side brakes locked. I was only going approximately twenty five MPH when all of this occurred. I stopped in the emergency lane and got out of the car. I saw nothing visibly wrong and started up the emergency lane and the brakes continued to lock as I was going up the emergency lane. I got the car to the first exit and took that exit. I parked the car in a private business and had it towed from there.
