Purchased with 9000 miles.Bought extended warranty to 86,000 miles (lucky for me.Had engine replaced 40,000 miles-5 truck latches-4 sets of brakes-alarm-6 oxygen sensors-water pump-fuel inject-steering column smoked-heater core-air condition does not work-brakes wear uneven-brake light switch-blinker light switch. Told all problems are common for this car. Maybe we would think about improving.Also ABS and engine light always on now-whats up with that? I love the style and comfort. What a nightmare of a car.I now need to new headlight assemblies that are about $700.00 from Cadillac.I have 179,000 miles on it at this time.Oil use is still more than normal. Mileage 19-20 in town,24-28 on highway.
I love the comfort and ease of driving.The style of the car is awesome.Traveling is real enjoyable in this car.I have rented alot of cars while on trips and still love to come back home to my STS.
