Most reliable car ever made.
Most reliable car ever. Good gas mileage. Low maintenance.

If they still made these - I would buy another one just like it.
I love this car from the stylish exterior to the leather interior. I average 25 miles to the gallon no matter what. The v6 engine provides as much power as you would want. I have maintained the car as recommended, the car has not had any major issues. There is a plastic piece around the base of the driver seat that has broken 4 times and had to be replaced. Even though the cost was minimal, it was irritating. Has been a classy, stylish, reliable vehicle. My only regret is they do not make them anymore as I would buy one just like it.

All wheel drive kicks in automatically as traction control.
Batteries in remotes go bad if you keep them too close to each other, good fuel mileage, hail damage all over, wear and tear on inside as well as outside of the car, automatic windows, child lock, remote start, heated seats, temp control on both sides of the car, all leather interior.

It drives smooth and corners like it's on rails. It can stop on a dime and has no problems with changing altitude.
This car travel 1900 miles through the Colorado mountains and didn't miss a beat. It corners well, and drives smooth as silk. It has great acceleration and while it doesn't slam you back in your seat it would still be competitive with a sports car.

Cadillac STS turns heads!
The Cadillac brand is a trusted name in the business! It has provided me with honest and timely service and my car is equipped with fantastic safety features, luxury options, and is completely reliable. It has many options which I found useful and efficient such as on window display, front and rear collision alarms, side view mirror warnings for when cars are next to you. It is comfortable, safe, and a real eye catcher too! I especially like the atmosphere controls in the back seat that can be different from the front seats allowing a personalized and comfortable experience for all passengers! The space the car has is also a plus providing comfort for long distance drives! Cadillacs are expensive to fix and maintain but the quality cannot be beaten!

It has rear backup security. When you get too close to something a alarm goes off. There is also a blinker alarm if you leave your blinker on for too long.
My car is lite colored and does not show dirt, it is comfortable to sit in and driving is a dream. I would like to get better gas mileage and the car has rust on the wheel wells and probably needs shocks or springs as it is not a smooth ride.

2008 Cadillac sts is a smooth ride and gets great gas mileage.
To replace a headlight the entire front bumper and grill has to be removed also a tail light cannot be replaced the entire assembly has to be purchased at $1, 800 each also the service tire monitor light blinks constantly but the tire pressure is fine.

Engine block failure
At 92000 mile the engine block failed from the inside out. Cost of repair by Cadillac 11000 to 12000. Repair at used car sales 5000 to 6000. Blue book 9000. Sold for 3500. Mary Barra refused to protect the consumer. They said my extended warranty expired a year ago. So it is my problem. Not bad consumer protection for a disabled veteran that bought nine Cadillacs for his family.

Pros from Owners

likeFilled Garth K.

It is a comfortable ride, sunroof, heated seats, heated steering wheel, great pick up, has rearview mirror dimming as well as side view mirror, v6 engine, has back seat heated seats, plus environmental controls for passenger and back seat as well.

likeFilled Dim C.

I really like the grill design and sunroof. I like the speed it has and the leather seats. I mostly like out of all the features the fact it has heated seat and the very comfortable black leather design.

Cons from Owners

dislikeFilled Garth K.

Bad gas mileage, my vehicle was involved in two car accidents, first one was a total loss. The amount to fix the vehicle was more than the vehicle was worth. The car had to have brand new tires. None of general maintenance was ever done to date. Sunk 1500 and will need another 1200 to make sure it is running correctly, plus any issues are Cadillac issues meaning it will be expensive.

dislikeFilled Dim C.

The cons is the parts are very expensive to replace it cost me 100 dollars just for a new light for it, and also many parts to seem to break more often than other brands, also its a tougher car to fix they put the bolts and parts in hard to access locations.
