Our Take

from the Cars.com expert editorial team

Vehicle Overview
The full-size rear-wheel-drive Q45 serves as Infiniti's flagship sedan. A new Sport model with Rear Active Steer, a sport suspension and 19-inch wheels emerges for the 2006 season. Rear Active Steer adjusts rear-suspension geometry according to steering input and vehicle speed. A Bluetooth-based hands-free phone system is standard, and Infiniti's Lane Departure Warning system has been added to the available Premium Package. The modified five-speed-automatic transmission has wider gear spacing and rev matching.

Exterior
For 2005, the Q45 adopted new front and rear fascias, a restyled hood and grille, new headlights and a different deck lid. LED taillamps are installed, and the body is adorned with chrome trim.

The heated mirrors have a memory function and a selectable tilt-down feature when in Reverse gear. The trunk lid can open and close automatically.

The Q45's seven-lens high-intensity-discharge headlights are among the most powerful installed in a passenger car. Alloy wheels hold 17-inch tires on the base model; titanium-finish 19-inch wheels are mounted on the Sport sedan. A tire-pressure-monitoring system is standard, and run-flat tires are optional. Built on a 113-inch wheelbase, the Q45 is 200.8 inches long overall, 58.7 inches tall and 72.6 inches wide.

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.
