2001 Cadillac Seville STS Problems

Excessive Engine Oil Consumption

Vehicles equipped with the 4.6L engine may develop excessive oil consumption. Please be advised that under optimum driving conditions, using one quart of oil every 2000 miles is acceptable. This Cadillac standard applies to vehicles with less that 50,000 miles. Our technicians tell us that if you experience excessive oil consumption it may be caused by built up on the piston rings which restricts movement, preventing them from wiping all the oil from the cylinder walls. Oil left behind is then burned during the combustion process. There is a special ring cleaning procedure which can help this situation. The GM service bulletin number is #02-06-01-009C.

Coolant Leaks From Water Pump and Radiator

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.

Engine Overheating May Cause Cylinder Head to Expand

Overheating of the engine may cause the cylinder head to expand, severely straining the head bolts and damaging the threads in the engine block. This commonly results in a blown head gasket. Our technicians tell us the engine block threads must be repaired before the cylinder head is reinstalled.

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 ST...
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 ...
