The vacuum release actuator for the parking brake may fail, preventing the parking brake from releasing automatically. Our technicians remind us that there is a mechanical release lever on the park brake ratchet you may use if the park brake does not release automatically. (Care should be taken when manually releasing the park brake!)

Most reported Cadillac problems
A common source of oil leaks is from the rubber transmission cooler lines. The fluid will often be red in color.
The anti-lock brake (ABS) accumulator may fail causing loss of power brake assist. (The brake pedal will become very hard.)
The air conditioning compressor may develop an abnormal noise and require replacement. We recommend that whenever an AC compressor is being replaced for a noise condition, a filter kit should be installed to prevent any metal particles in the system from damaging the new compressor.
Excessive carbon build up in the engine combustion chambers may be the cause of a smog check failure due to excess NOx emissions. A "top engine" decoarbonization cleaning procedure will commonly correct this concern.
Illumination of the Check Engine Light may be the result of a loose or worn gas cap.
One or more fuel injectors may become stuck closed causing an engine misfire and the Check Engine Light to illuminate. Our technicians tell us that this problem can be caused by some fuel additives. There are special procedures which may be able to restore the affected injector. If this fails the affected injector must be replaced.
One or more of the power window regulators (one in each door) may fail causing the window to fall into the door and not roll up.
It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.
The transmission may develop a harsh 1-2 shift and/or illumination of the Check Engine Light with code P1870 stored. This can be caused by wear of the bore for the TCC isolator and regulator valves in the valve body. This condition does not commonly occur until the transmission reaches normal operating temperature. If the valve body is worn, replacement will be necessary to correct this concern.
i got trapped in the tranny replacement thinking i would never have to worry about it again, hah 2 months after the warranty its back. 3year 100,000 miles warranty and 40,000 miles later the 4000 dollars i had put in the car is all for nil. this motor drivetrain has so many service bulletins it is a another high end GM rip off,that was junk to begin with and Cadillac wont own up to it.
