2009 Cadillac DTS Service and Repair Manual

Known issues on the 2009 DTS. Two recalls are on federal record for this model year. The first covers the ignition system: a heavy key ring can jar the key out of the run position, which can disable the air bags and cause a sudden loss of engine power, power steering, and power braking. The second covers the electrical system, specifically the heated washer fluid module, which can ignite and start a fire. Owners have filed 35 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.
From a key-cylinder and ignition-switch inspection to washer-module wiring checks or a routine service interval, it keeps you on the OEM procedure and the correct specification for your specific 2009 DTS.
