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.

Specific symptoms reported on the 2007 Cadillac STS
Recalls 2
Fuel system, gasoline: delivery: fuel pump
- What is wrong
- 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.
- Risk
- 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.
- Remedy
- 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.

Most recent owner complaints, unedited.
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 service airbags warning appeared on my car. It was just parked for 2 days and when I got in it turned on. This is a common issue that has occurred with multiple people.
On my way home today the service light airbag come on stating that the airbag needs to be serviced.
Tl* the contact owns a 2007 cadillac sts. The contact stated that when an occupant was seated in the front passenger seat, the passenger side air bag sensor did not illuminate. The contact stated that the vehicle was experiencing the same symptom as listed in the federal safety agency campaign number: 10v644000 (air bags). The vehicle was taken to an independent mechanic who stated that the passenger seat switch module needed to be replaced. The vehicle was not repaired. The manufacturer was notified, but was not able to assist. The failure mileage was 169,000.
The federal safety agency campaign #14v542000, recall id #226957 - fuel system issues, effective 03/12/2015. Notified by credit karma on sunday, 11/04/2018. I purchased this vehicle in 2011. Within the first month, the vehicle would not start after filling the gas tank the night before. Initially I thought perhaps it was a bad batch of gasoline. I filed a claim again my warranty, requested information from thomas petroleum who confirmed there was no issue with gasoline, warranty covered repair. Then again in 2016, I have experienced the same issue with fueling system. Please see attached diagnostics from autozone. I have since then purchased another vehicle and 2007 cadillac sts presently inoperable. I was advised of recall from creditkarma
2007 cadillac sts. Consumer writes in regards to defective composite headlamps. *ld the consumer stated the headlamp assembly would fog up. There was two inches of water built up in the assembly due to condensation.
I went to the gas station to fill a gas. After I filled the car I saw big spot underneath of my car of gasoline. I went under the car I saw some gasoline color on the fuel tank. The dealer refused to fix it under the claimed recall.
Left headlight fills with water during a rainstorm or car wash. Headlamp is foggy with moisture reducing the light output and will cause a premature headlamp failure.
Air bag light came on and the dic indicates the air bag requires service. Upon investigation, the passenger presence sensor in the passenger seat is shot. The air bags are disabled and it's a thousand dollar repair at the dealer. Rarely does anybody sit in the passenger seat. It appears that this passenger side sensor is a common failure in other gm models as well.
