Overview & Reviews

The 2008 Cadillac STS has been significantly updated. Beyond revised styling and a more luxuriously trimmed interior, several high-tech safety and performance options keep this all-American Cadillac competitive in the luxury sport sedan segment. The base-trim STS also features a more powerful and efficient 302-horsepower V6 coupled to a six-speed automatic transmission.

• Optional Bose stereo is one of the best in its class.
• Low price for a full-size luxury sport sedan, powerful new V6, nimble road feel for such a large car, sporty all-American looks, available all-wheel drive

• Sporty front seats might be too firm for some posteriors, interior plastics not quite up to the standards set by the top-ranked competition.

  My first Cadillac - 2008 Cadillac STS
  By powerline87 - August 5 - 6:39 pm

  This is my first Cadillac and my first car that was over $1000. Value: I got my car 3-4 years old, because the price drops by $20-25k by then. Performance: 302hp 3.6L DI V6. 52/48 weight dist. AWD. Dual-Wishbone front suspension - It handles better than most smaller cars Ive driven, and even handles about as well as the CTS, despite being bigger and more comfortable. Comfort: I have driven a Lincoln MKZ, a Cadillac CTS and SRX, and a Lexus ES 350, and the STS is the most comfortable out of all of them. It is roomier and its seats just feel more comfortable. Summary: A used 2008-2011 Cadillac STS has a better balance between luxury and performance than any other car in my price range.

  Bose Stereo Issue Debugged - 2008 Cadillac STS
  By cfazzari - June 4 - 2:02 am

  In an earlier review I wrote the Bose system was basically terrible. The lows had no THUMP the Mids were Watery and the highs were muted. Apparently There are five different listener settings: Centerpoint, Driver, Talk, Normal and Rear. Centerpoint is the setting to use. The other four settings make the system sound awful at high volumes. Centerpoint wakes up the entire system and is easily comparable to the Boston Acoustic sytem I just came out of from my SRT8 Charger.

  I fall in love everyday - 2008 Cadillac STS
  By KRSTS - June 20 - 10:13 am

  I have owned this STS for 27 months and I love it more everyday. It was a GM owned CPO with only 8200 miles. This is my third Cadillac. My others were all V8s and I do not miss the V8 at all. The V6DI is great engine, not only for the power but the fuel mileage. The car is very comfortable on long trips and handles like a dream. There were a few minor issues early that were promptly fixed by the dealer. Now I only take it in for an annual oil change and inspection. Best car I have ever owned in my 67 years.

  1st Cadillac, Great Car - 2008 Cadillac STS
  By Matt - March 9 - 1:39 pm

  This was my 1st Cadillac. I purchased it new in Dec 09. It was on the dealer lot of 1.5 years and I got a great deal. After reading all of the reviews, was worried about build quality and reliability. I have been very happily surprised. Ride quaility is #1, handling and V8 performance are great. I am in my mid 40s and looked at Lexus, Infiniti, MB. The caddy, for the price, exceeded those other car makers. My younger friends have all been impressed with this car and are looking a Cadillac instead of a BMW or lexus. I hope that GM will continue to improve the model. At this writing, I dont think I will purchase anything but a Cadillac again. I have been very satisfied.

  Very Happy - 2008 Cadillac STS
  By richcory - October 28 - 3:38 pm

  Wife and I bought our 08 STS V8 in March of this year and it had 13000 miles on it. We like it so much that we have driven to to Vegas, Denver and Ohio from our home in Oklahoma. Wife drives it every day to work and another 13000 miles later we couldnt be happier with our purchase. On the trip to Vegas and back we averaged 30 MPG with 4 adults and trunk full of luggage. Sound system is the best of any factory system available. Nav is good but could be more user friendly. Interior storage space could be improved upon and the glove box is a joke. Overall a great car with lots of performace and fun to drive. Its performace isnt that far off from my 94 Vette.

  Finally GM Got it right...For Now - 2008 Cadillac STS
  By Old Red - June 27 - 12:17 pm

  I purchased two new GM vehicles in 2008, a Cadillac STS AWD and a Silverado 1500 LTZ 4WD. The quality of workmanship was the best Ive ever seen in my 53 years of owning and driving all kinds of cars. 0 defects, good fitment, quality throughout. As good over better than any foreign car or truck Ive ever been exposed to. Thinks I, "Theyve finally got it right".

  Stay Away From The Northstar V8 - 2008 Cadillac STS
  By Will - February 16 - 5:49 pm

  I have owned 2 Cadillac STSs thus far. The First was a 2005 with the V8 and the one I have now is a 2008. They are great cars for the thought but stay away from the V8 North star engines by all means. At around 87, 000 and up the V8 North star starts going to the ground with problems. The found out problem with this engine is the design for the cylinder head mounting studs start to loosen due to corrosion and the material or metal used for the Head studs that clamp them down. This leads to head gasket failure and even engine damage. You can get the head gaskets fixed but the problem will come back after 30,000 miles or so, ultimately leaving you with a reoccurring and expensive problem. You can re-drill new studs in the engine and the problem still will come back. Its a nice luxury / performance car overall but I recommend buying the V6 with the 306hp. Oh and on my 2005 car the transmission started to give up on me. I think the 5 speed can barely handle the V8 power, the 07 and up have 6 speeds that are more adequate.

  Lemonade - 2008 Cadillac STS
  By LarryG - January 16 - 7:20 am

  Leased my 2008 STS in late December, 2007. Failed camshaft sensor, failed right side cam at 13,000 miles, deffective FOBs, 5-burned out lights, deffective drivers seat lumbar system. Dealer is great but car spends too much time in service bay. Will not lease or buy another GM product. Totaly fed up.

  Bad Paint - 2008 Cadillac STS
  By Herb - December 6 - 1:56 pm

  Love it, except the paint. The car is black, and I had it waxed immediately, by a professional. The first time I cleaned it myself, I discovered many pock marks on the hood and rear deck. They are in the paint, and wax does not remove them. I am taking it into the dealer to check. The paint is defective, and I hope someone will back it up.

  Solid player - 2008 Cadillac STS
  By jeff sunshine - November 10 - 1:39 pm

  I purchased mine at the end of August when there were only V6 AWD models. I traded my V8 STS and thought I would be taking a step down. With V6 DI engine, I really do not miss the V8. So far this car is solid in all respects handles well,comfortable, reliable, good mileage and is fast enough. In my opinion, this car favorably competes with BMW, MB and the other usual suspects but after you negotiate your final price, there really is no comparison becuse you pay a lot less. The status of a label is unimportant to me (although a Caddy still has some clout left) and as car enthusiast, I look to the raw driving experience. STS is right there and if the V8 G8 had AWD, I would be driving that.
