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.

  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.

  STS Brakes and Front End - 2005 Cadillac STS
  By gojo2 - March 15 - 5:13 pm

  Our 2005 Cadillac STS is not as reliable as the Lexus weve owned. Weve had problems with the brakes and the front end. The dealer and Cadillac are not as friendly to customers as they claim.

  I have to admit, being 30 years-old and buying my 6th Caddy, this one is the nicest by far. Every time I am out, people comment on the sleekness of it and its stately appearance. They do have to fix a couple things on it however (stated below). But overall, its American made and put together cheaply. Its only worth $30,000 at the most.

  Almost Perfect! - 2005 Cadillac STS
  By stephen leonhard - December 4 - 2:20 pm

  This cars seats are downright uncomfortable after three hours. The interior is cheap looking and hard surfaces abound. The glove box barely holds the owners manual. Altogether too much tire and road noise enters cabin. It requires 150 pounds of sand bags in trunk to get modest winter traction. Having said this, this car has great handling. The steering and brakes are excellent.

  Tires - 2005 Cadillac STS
  By J.Stiles - October 26 - 9:57 am

  At 10,000 miles my STS developed a thumping noise, which was especially noisy at low speed. Our dealer diagnosed this as a tire problem and replaced (free of charge) our front tires. The noise dissipated to almost nothing, it is but still noticeable in the rear tires. I was a little surprised that the dealer charged us for a full alignment on the new tires.

  Transmission! - 2005 Cadillac STS
  By Chris - July 13 - 1:54 pm

  My STS transmission is awful! When downshifting, it has trouble finding a gear, especially when you want to re-accelerate. It makes for a very rough ride. At speed, its okay. Also, its voice recognition is poor. The electronics are too complicated, too. The learning curve is fairly steep. I also dont like the adaptive cruise control. Bluetooth is a joke as well.

  Switched - 2005 Cadillac STS
  By Arturo - June 26 - 10:38 pm

  I had to have the the fuel tank in my 05 STS replaced, the fuel gauage repaired, and replaced the main module that controls the memory. I was informed after purchase that the DRL will not function if you opt to engage the auto rain sensing wipers even if the manual indicates that you can.

  STS Power! - 2005 Cadillac STS
  By Anthony Cronin - March 26 - 7:59 pm

  I have had this car for almost a year now. Every option has come into play by now and the ride is comfortable and very aggressive. The Tiptronic transmission isnt very good at all though. It has no control nor has any power behind it. I drive the STS about 400-550 miles a week and I love it. It is great on long trips and very economic in your daily drive around neighborhood. It has had a few computer problems, or re-calls. But I think that the wear is partial to that. I love the car, I definitely want another STS in the near future.

  After One Year - 2005 Cadillac STS
  By pb - January 5 - 1:06 am

  I have driven my 2005 Cadillac STS for 12 months and find that it meets most of my expectations. Coming from a 2002 BMW M3 (and a BMW 540 prior to that), I was looking for more room and creature comforts. Wishing to buy American, I chose the STS V8. I have had only one signifcant problem, the steering column came loose after two months apparently from a manufacturing defect. Cadillac replaced it promtly and I had no further problem. Overall, this car is a great combination of power and a smooth ride, with useful technology (navigation, remote start, and terrific sound system-you must listen to 5.1 channel musice CDs in this vehicle). All this and its American!
