2001 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 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.
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.

2001 Cadillac Seville STS Reviews
Replacement HID Headlights cost more at the Cadillac Dealer Parts Dept. than what the whole car is worth used. Other than that, I believe this is the best car for the money .... that money can buy. I made the mistake of buying my wife a used 2001 Seville STS , and now I'll have to pay four times what I paid for this car, to replace it with ANY make of car that is only half as nice as this STS was when i bought it.
I have owned my Cadillac since it was new in 2001. Now with 100,000k miles, I have had absolutely no major issues with it at this point in time. Now the car does have the common North Star Oil leak, and it has had the intermediate shaft replaced. Those are not serious failures. But these are the common issues, and I don't care about a little bit of oil under my 9 year old car. All in all, this car has been very trouble free and it has more performance and handling than half the cars out there, and it will keep going for as long as I keep taking care of it.
