2009 Cadillac DTS Problems
RepairPal has identified the most common problems with the 2009 Cadillac DTS based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The engine may develop an oil leak from the lower crankcase portion of the engine block. Our technicians tell us that the engine must be removed from the vehicle to properly repair this oil leak.
The steering wheel position sensor may fail, resulting in the service stability message being displayed.
An automatic transmission fluid leak may develop from the rubber section of a transmission cooler line. In some cases the rubber section of hose can be replaced. In others, the complete cooler line must be replaced to correct this type of leak.
The 2006-2011 Cadillac DTS may have issues with the EVAP system, a part of your emission control system.
To correct the issue, the EVAP canister vent valve, solenoid, and wiring must be inspected. The most common fix is replacement of the wiring connector or replacement of the vent valve assembly.
A Loose or worn gas cap may cause Check Engine Light to illuminate.
The fuel pump may fail causing the engine to stall and not restart.
The anti-lock brake system (ABS) control module may fail causing the ABS light to illuminate. Failed modules should be replaced to restore ABS operation.
The parking brake may not release automatically due to a failed vacuum switch or actuator. Our technicians tell us that if vacuum is supplied to the actuator when the transmission is in gear, the vacuum switch is functioning and replacing the actuator should correct this concern.
