2015 Buick LaCrosse Review

from the expert editorial team reviewer Mike Hanley said the 2015 Buick LaCrosse full-size sedan fits right in with the brand's ongoing renaissance. "It's comfortable, it's quiet, it's well-crafted, but there's room for improvement in a few areas."

What Is the 2015 Buick LaCrosse?

The 2015 Buick LaCrosse is a full-size sedan that seats five. It's offered in five trim levels, including 1SV, Base, Leather, Premium I and Premium II. Front-wheel drive is standard, but all-wheel drive is available on Leather and Premium I. Competing models include the Chrysler 300 and Toyota Avalon.

What's New on the 2015 Buick LaCrosse?

For 2015, 4G LTE internet connectivity with an in-vehicle Wi-Fi hotspot is added to the OnStar communication system (subscription required). Additionally, Buick's IntelliLink system now features Apple Siri Eyes Free for iPhones and can read inbound text messages. The LaCrosse also gets a backup camera and front seats with four-way-adjustable head restraints.

How Does the 2015 Buick LaCrosse Compare to Other Full-Size Sedans?

Even against luxury competitors, the Buick LaCrosse is a good value. After a 2014 redesign, it sported comfier seating for the driver and better ergonomics. The LaCrosse has a handful of foibles, such as a mushy brake pedal and poor outward visibility, but it seems to improve with each generation.

What Features in the 2015 Buick LaCrosse Are Most Important?

The 2015 Buick LaCrosse can be powered by a mild-hybrid drivetrain: the 2.4-liter four-cylinder engine, an electric motor/generator and a lithium-ion battery pack. Altogether, the system generates 182 horsepower. Front-wheel drive and a six-speed automatic transmission are standard. Options include a 304-hp, 3.6-liter V-6 engine, all-wheel drive and an adaptive suspension.

Standard features include 17-inch alloy wheels, LED taillights and active grille shutters that close at highway speeds to improve aerodynamics. Cloth upholstery, IntelliLink with a tablet-style interface, and 8-inch dashboard and instrument-panel screens are also standard. Optional features include 18-, 19- or 20-inch wheels, bi-xenon high-intensity-discharge headlights with LED daytime running lights, a power moonroof, leather upholstery, a Bose premium stereo, a navigation system and a head-up display. An Ultra Luxury Package is also available, adding a simulated-suede headliner, perforated leather upholstery and wood trim.

As is required in all new cars of this model year, the LaCrosse has front airbags, antilock brakes and an electronic stability system. Side curtain airbags, side-impact airbags for the front and rear seats, and a backup camera are also standard. Several driver assists are available for the LaCrosse, including lane departure warning, forward collision warning with automatic braking, rear cross-traffic alert, adaptive cruise control with full-stop capability, and a blind spot warning system with lane change alert – which warns of distant but fast-approaching cars in the next lane. Safety Alert Seat is also available; it works with other safety systems to warn the driver by pulsing the seat cushion.

Should I Buy the 2015 Buick LaCrosse?

In addition to a mushy brake pedal and restricted visibility, the Buick LaCrosse suffers from a small trunk, touch-sensitive climate controls and a lightly colored dash that reflects in the windshield. If none of those traits are bothersome for you, the LaCrosse is a good choice. Good steering response and feedback, a quiet cabin and a smooth optional V-6 are among its strongest qualities.'s Editorial department is your source for automotive news and reviews.

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.
