2010 Cadillac STS Reviews

Vehicle Overview
Cadillac's midsize sport sedan, the STS, features a powerful base engine, an optional V-8 and a variety of high-tech safety options. The STS competes with the BMW 5 Series, Lincoln MKS and Hyundai Genesis.

New for 2010
The 469-horsepower STS-V has been discontinued.

The STS' bumper is prominent, and its grille is dominant. Like it or not, you have to admit that the elements are in proportion, from the plunging grille to the stacked headlights and fog lights. A Platinum Edition Package, optional with either engine, adds a new grille finish and 18-inch chrome wheels.

  • Rocker-panel moldings
  • Small spoiler
  • Chrome door handles
  • Polished-aluminum dual exhaust tips
  • Standard 17-inch alloy wheels, optional 18-inch alloys

The STS can have optional wood trim; real metal trim accents the steering wheel and dashboard. The Platinum Edition augments the cabin with a leather dashboard and a suede-like ceiling.
  • Optional head-up display projects vehicle speed and other selectable readouts on the windshield
  • Optional adaptive cruise control and remote-start systems
  • Standard eight-speaker Bose stereo
  • Optional 15-speaker, Bose 5.1-channel surround-sound stereo
  • Standard leather seats, dual-zone climate control
  • Optional heated steering wheel
  • Optional heated and ventilated seats

Under the Hood
The base STS' 3.6-liter V-6 has direct injection and produces 302 hp and 272 pounds-feet of torque. An optional 4.6-liter V-8 makes 320 hp and 315 pounds-feet of torque. Both engines use a six-speed automatic transmission.
  • Optional Performance Handling Package includes Brembo four-piston calipers with larger brake discs

Safety equipment includes:
  • Standard front and side-impact airbags and side curtain airbags
  • Standard antilock brakes, electronic stability system
  • Optional lane departure and blind spot warning systems
  • Optional Intellibeam headlamps that self-adjust their intensity based on oncoming or leading vehicles

Reliable, comfortable & stylish

by Cadillac Guy from Roanoke, VA on November 3, 2017

This car is the best I've ever owned, AWD, good on gas, and has been very reliable. I love the way it looks, & the way people look at it (it gets attention!)

What you should get in your warranty can be confusing. Make sure you are informed.

Learn More About Warranties

Warranties Explained


Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance like fluid top offs and oil changes, but a few brands have separate free-maintenance provisions, and those that do offer them is slowly rising. Bumper-to-bumper warranties typically expire faster than powertrain warranties.


Don't be misled a 10-year or 100,000-mile powertrain warranty doesn't promise a decade of free repairs for your car. It typically covers just the engine and transmission, along with any other moving parts that lead to the wheels, like the driveshaft and constant velocity joints. Some automakers also bundle seat belts and airbags into their powertrain warranties. With a few exceptions, powertrain warranties don't cover regular maintenance like engine tuneups and tire rotations.

Roadside Assistance

Some automakers include roadside assistance with their bumper-to-bumper or powertrain warranties, while others have separate policies. These programs cover anything from flat-tire changes and locksmith services to jump-starts and towing. Few reimburse incidental costs like motel rooms (if you have to wait for repairs).

Free Scheduled Maintenance

Some automakers include free scheduled maintenance for items such as oil changes, air filters and tire rotations. Some include consumables including brake pads and windshield wipers; others do not. They are typically for the first couple of years of ownership of a new car.
