2011 Cadillac STS Review

from the Cars.com expert editorial team

Vehicle Overview

Cadillac’s midsize sport sedan, the STS, features a powerful V-6 and a variety of high-tech safety options. The STS competes with the BMW 5 Series, Lincoln MKS and Hyundai Genesis.

New for 2011
The V-8 has been dropped, and the STS gets free standard scheduled oil changes, tire rotations, replacement of engine and cabin air filters, and multipoint vehicle inspection for four years or 50,000 miles through Cadillac’s Cadillac Premium Care Maintenance program.

Exterior
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. The optional Platinum Edition Package adds special badging and 18-inch chrome wheels. Exterior features include:

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

Interior
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 suedelike ceiling. Interior features include:

  • Optional head-up display projects vehicle speed and other selectable readouts on the windshield
  • 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

Solid, Dependable Car

Warranty FAQs

What is a Bumper-to-Bumper warranty?

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.

What is a Powertrain warranty?

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.

What is included in 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).

What other services could be included in a warranty?

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.

What does CPO mean?

A certified pre-owned or CPO car has been inspected to meet minimum quality standards and typically includes some type of warranty. While dealers and third parties certify cars, the gold standard is an automaker-certified vehicle that provides a factory-backed warranty, often extending the original coverage. Vehicles must be in excellent condition and have low miles and wear to be certified, which is why off-lease vehicles feed many CPO programs.
