Overview & Reviews

Cadillac's full size sedan is all new for 2005, rounding out the luxury marque's self-proclaimed renaissance with a bevy of performance-oriented credentials, including rear-wheel drive and two powerful engine options. Cutting-edge styling, lavish interior appointments and available all-wheel drive have brought GM's flagship up to par with the best Europe and Japan have to offer.

• Full-size car at a midsize price, nimble road feel, powerful engine options, available all-wheel drive, optional Bose stereo is one of the best in its class.

• Sporty bucket seats might be a bit firm for some, plastic interior panels not quite up to German standards, only one transmission available.

  Dont buy one - 2005 Cadillac STS
  By Paul - January 2 - 11:42 pm

  This was my dream car. I am a very loyal GM buyer over the last 25 years. I can tell you I will never own one again. This was the icing. Uncomfortable creeky seats, electrical problems, stereo problems, alarms going off in the middle of night. In all had the car in the shop for at least 18 times. To top it off, GM called me to offer money off my next one. The front tires are different size than back. No rortation=many tires. Rides like a Jeep! I am sorry if this is too harsh but if you looked at my carfax you would say Im being kind

  Superior exterior design - 2005 Cadillac STS
  By infinitetanner - November 6 - 2:57 pm

  This car has a stunning exterior design, and a nice cockpit layout. Its 4.6L 320 HP is responsive, however the transmission in the AWD has a delay- frustrating. Handles fantastic! Wont peel out though due to AWD system. I have the 1SG luxury edition, that offers: HID xenon head lamps, OnStar, XM, navigation with DVD player built in, 6cd changer, heated and a/c cooled front seats, heated rear seats, 18 rims, bluetooth hands free calling, one touch adjustable performance and touring suspention (formula 1 inspired), spoiler and much more! Despite being a tank, this car is small inside for rear passengers & front passenger. Glove box is a joke, trunk is decent-needs sunglassas holder badly!

  Good looks only! - 2005 Cadillac STS
  By 2005 STS - July 14 - 10:06 am

  Our car has been a lemon! Same tire thump as others reported & tires were replaced after about 4 trips to the dealer. Tires also after were replaced did not wear well or last long since can not be rotated. Power steering lines have been replaced. There was a burping noise coming from vents that was horrible as it sounded like someone was passing gas. Again after a few trips to dealer, some type of ventilation computer part was replaced. My car has been in the shop over a dozen times in 2 years. The problems were all "odd" and could not be diagnosed easily so there were many return trips. As other reviews have said when you buy a Cadillac you are not treated as if you buy a Lexus.

  Fantastic ride! - 2005 Cadillac STS
  By Glynn Campbell - June 7 - 10:33 am

  This is the sexiest car on the road, and is like driving your living room down the road, albeit a high performance living room! Quiet, comfortable and the most reliable car Ive ever owned

  Not For Me - 2005 Cadillac STS
  By 2005 STS - June 4 - 1:34 pm

  The STS is a sleek, stylish car, but difficult to drive. There are too many complications such as not being able to see out of the back window, when anyone else drives it i.e. my husband, the rear view mirror change direction, but do not change back when I drive, also the radio automatically changes to another station or the disc changes. I do not like not having a key and I do not like the door locks, just to name a few.

  I bought the STS lemon - 2005 Cadillac STS
  By Linda L. Felton - May 21 - 2:29 pm

  I purchased my STS in January, 2005 and was stranded on the highway by October, 2005 needing a new gear shift. Since December 21, 2006 I have been stranded with a dead battery six times and rough riding with the check engine light twice on Sunday trips of 200+ miles. By the time I get to the dealership after being delivered 5 new batteries in 3 years, the problem cannot be duplicated. Neither of the two dealerships have been able to duplicate the problems so they say there is no problem. There were 6 month intervals from 2006-2007 but 2008 has already recorded January 24, February 18, and May 18.

  2005 Cadillac STS Rwd 4dr Sedan 3.6L V6 - 2005 Cadillac STS
  By JNo - April 25 - 6:20 pm

  Fabulous. I bought this car used and have put over 6,000 miles on it in two months. It is simply built to smoothly take in the road. If I hold it under 80 I can get around 28 mpg, but wind resistance drags it down at higher speeds. I love the leather heated seats, and the way it was built to NOT accommodate a bunch of clutter. This car is a show piece and turns heads everywhere I go. Perfect.

  A Keeper - 2005 Cadillac STS
  By Caddy Lover - April 17 - 4:25 am

  Great in almost every way. Thought it was me, at 70, turning the chicks head, but turns out its the Red Line Red color. Guys if youre looking for women, forget e-harmony.com, get a 05 STS Red Line Red. Sleek in every way.Sorry i didnt buy the AWD.
