2002 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.

2002 Cadillac Seville STS Reviews
Love this car and the color mulberry red, like the caddy rims wish they were 18's. This car has everything sunroof heated seat and mirrors onstar bluetooth 6 cd changer power, speed, leather, backup sensors. just bought this for 5k W/ 135k mile good buy or bad whats your thoughts out there holla back.
Everything I ever wanted included leather interior and an easy to use dash, good mileage on cruise control, love the back up assist and moving mirrors. Small things like shift knob "wood" is faded. It goes through oil but I've had VWs that leak more. Reached 90K and just put on new tires and needed major overhaul on the power steering, alignment etc. Sometimes it's not as smooth on the freeway, steering wheel vibrates but maybe thats L.A.
Engine would make a good lawn ornament
