Engine Trouble After 3 years

2006 Cadillac STS V6 4dr Sedan (3.6L 6cyl 5A)

I bought my 06 STS after owning a volvo for 14 years. Never had to replace the motor or transmission. I thought I was going to own this car for a number of years without major problems. Wrong! In the shop now with engine problem. The price keeps going up just to identify what's wrong. Paid too much money to have problems so soon. I am now wondering if I made a mistake in purchasing this car. I thought this would be the car that would take me into retirement. It's a good looking car, but it has it's down falls such as useless glove compartment, limited storage space in doors, small truck for a med size nice looking car, noisy, and limited room in the back seats.
Glad I bought it used

2006 Cadillac STS V8 4dr Sedan (4.6L 8cyl 5A)
3 of 5 people found this review helpful
have read many reviews. I agree: a little firmer than my 2001 SLS. Not used to bumpier ride. Mileage is 13 in town and 19 on the road with hi test and Cad recommended fuel (Texaco). I test drove an 80,000 mile BMW 750i before and much nicer and same price. Retails for $101K now but an STS V-8 is easily $68K. Next time or next car: AWD
Not Happy

There are a few important things that I don't like about the 2006 STS. The foot-well is so cramped that if you are like me, 6 feet tall, your right knee will rest against a very uncomfortable sharp hard-padded bolster. The glove compartment is too small for such a large car...once the owner's manual is in, there is no room. The trunk acess is poor. The dash design is bland and could be much more luxurious.
Don't Buy This Car - At least the 2006

I purchased a Certified 2006 STS w/ 20,000 miles in July 2008. Excellent condition. I traded my Toyota Solara with no regrets until ... the moaning sounds started. Forget driving this car on long interstate trips involving mountains. This is the most annoying noise ever. I've had it to the dealer 6 times for repair without any luck. They claim to "reprogram" whatever it is they "reprogram," but it never repairs the problem. I didn't think a car like this with over a $55,000 price tag new would have so many problems. I cannot speak for the V6, but the V8 is not up to par with even the 3.0 V6 in my former vehicle the Solara. I'm ready for another Toyota! Tell me again why GM is in a mess?
The greatest disappointment of Cadillac

I have been driving Cadillacs for the past 16 years. I have had DeVille's and SLS's. Always I could rely on Cadillac to provide superior ride and service. My 2006 STS V6 was a huge disappointment. We have 8,000 miles on the car and have felt every crack in the road from here to Florida and back. We cancelled a Christmas driving trip and chose to fly. The ride is intolerable. Never before have we had to test drive the car before ordering. We find that the only smooth ride offered by Cadillac is the DTS. We like the sporty styling but its a tin-lizzy dressed in sports attire. Second, the glove box is not sufficient to even house the car's instruction manual. What a useless piece of space.
