2000 Cadillac Seville STS Problems
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 trunk pull down switch may fail causing the trunk lid not to close completely. Our technicians tell us that the failed switch can be replaced without changing the complete pull down motor assembly.
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.
The water pump and/or the plastic side tanks on the radiator may leak causing a loss of coolant. The engine may overheat due to coolant loss. Continued coolant loss after external leaks have been repaired could indicate a blown head gasket.

2000 Cadillac Seville STS Reviews
Car runs even better than the day that I purchased it. Purchased at 82K miles needed new brakes, tires, and crankshaft sensors but runs like new now. The handling is great for a car as big as it is and it rides smooth although the brakes you have to stomp on to get the car to stop(maybe bigger breaks on a 4000 pound car next time GM) But the engine and the exhaust systems run amazingly no issues except the north-star oil leak. Accessories are top notch as well
Very comfortable to drive, good appearance, I don't want to trade it in for a newer model.
