Safety

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the LaCrosse are reminded to check the back seat if they opened the rear door before starting out. The Accord doesn’t offer a back seat reminder.

The LaCrosse offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Accord doesn’t offer all-wheel drive.

Both the LaCrosse and the Accord have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems, front parking sensors and rear cross-path warning.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Buick LaCrosse is safer than the Honda Accord:

Warranty

The LaCrosse comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Accord’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.

Buick’s powertrain warranty covers the LaCrosse 1 year and 10,000 miles longer than Honda covers the Accord. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Accord ends after only 5 years or 60,000 miles.

The LaCrosse’s corrosion warranty is 1 year longer than the Accord’s (6 vs. 5 years).

Buick pays for scheduled maintenance on the LaCrosse for 2 years and 24,000 miles. Buick will pay for oil changes, lubrication and any other required maintenance (up to 2 oil changes). Honda doesn’t pay scheduled maintenance for the Accord.

There are almost 2 times as many Buick dealers as there are Honda dealers, which makes it much easier should you ever need service under the LaCrosse’s warranty.

Reliability

The LaCrosse has a standard “limp home system” to keep drivers from being stranded if most or all of the engine’s coolant is lost. The engine will run on only half of its cylinders at a time, reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The Accord doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the car’s engine.

The battery on the LaCrosse is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the LaCrosse’s battery 20 to 30 degrees cooler, its life is increased by years. The Accord’s battery is in the hot engine compartment.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Buick vehicles are better in initial quality than Honda vehicles. J.D. Power ranks Buick 16th in initial quality. With 7 more problems per 100 vehicles, Honda is ranked 23rd.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Buick vehicles are more reliable than Honda vehicles. J.D. Power ranks Buick third in reliability, above the industry average. With 24 more problems per 100 vehicles, Honda is ranked 12th.

Engine

The LaCrosse’s optional 3.6 DOHC V6 produces 58 more horsepower (310 vs. 252) than the Accord’s optional 2.0 turbo 4 cyl.

As tested in Motor Trend the Buick LaCrosse V6 is faster than the Honda Accord 1.5 turbo 4 cyl. (automatics tested):

Fuel Economy and Range

An engine control system that can shut down half of the engine’s cylinders helps improve the LaCrosse V6’s fuel efficiency. The Accord doesn’t offer a system that can shut down part of the engine.

Regenerative brakes improve the LaCrosse eAssist’s fuel efficiency by converting inertia back into energy instead of wasting it. The Accord doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the LaCrosse’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Accord doesn’t offer an automatic engine start/stop system.

The LaCrosse FWD’s standard fuel tank has a gallon more fuel capacity than the Accord (15.8 vs. 14.8 gallons), for longer range between fill-ups. The LaCrosse AWD’s standard fuel tank has 1.4 gallons more fuel capacity than the Accord (16.2 vs. 14.8 gallons).

Brakes and Stopping

For better stopping power the LaCrosse’s brake rotors are larger than those on the Accord:

Tires and Wheels

For better traction, the LaCrosse has larger standard tires than the Accord (235/50R18 vs. 225/50R17). The LaCrosse Essence/Premium/Avenir’s optional tires are larger than the largest tires available on the Accord (245/40R20 vs. 235/40R19).

For better ride, handling and brake cooling the LaCrosse has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Accord. The LaCrosse Essence/Premium/Avenir’s optional 20-inch wheels are larger than the 19-inch wheels on the Accord Sport/Touring.

Suspension and Handling

For a smoother ride and more stable handling, the LaCrosse’s wheelbase is 3 inches longer than on the Accord (114.4 inches vs. 111.4 inches).

The LaCrosse Premium handles at .84 G’s, while the Accord EX pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

The LaCrosse Premium executes Motor Trend’s “Figure Eight” maneuver quicker than the Accord EX (26.8 seconds @ .66 average G’s vs. 27.7 seconds @ .61 average G’s).

For better maneuverability, the LaCrosse’s turning circle is .1 feet tighter than the Accord’s (38 feet vs. 38.1 feet). The LaCrosse’s turning circle is 1.4 feet tighter than the Accord Sport Manual/2.0T’s (38 feet vs. 39.4 feet).

Chassis

As tested by Car and Driver, the interior of the LaCrosse Premium is quieter than the Accord Sport:

Passenger Space

The LaCrosse has .1 inches more rear hip room and .1 inches more rear shoulder room than the Accord.

Cargo Capacity

The LaCrosse’s standard folding rear seats are split to accommodate bulky cargo. The Accord LX’s standard single piece folding rear seat is not as flexible; long cargo and a passenger can’t share the rear seat.

Towing

The LaCrosse’s standard towing capacity is much higher than the Accord’s (1000 vs. 0 pounds).

Servicing Ease

The LaCrosse uses gas struts to support the hood for easier service access. The Accord uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

J.D. Power and Associates surveys of service recipients show that Buick service is better than Honda. J.D. Power ranks Buick 9th in service department satisfaction (above the industry average). With a 41% lower rating, Honda is ranked 25th.

Ergonomics

The power windows standard on both the LaCrosse and the Accord have locks to prevent small children from operating them. When the lock on the LaCrosse is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Accord prevents the driver from operating the other windows just as it does the other passengers.

The LaCrosse’s front and rear power windows all lower with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Accord’s rear power window switches have to be held the entire time to open them fully.

To help drivers see further while navigating curves, the LaCrosse Sport Touring/Essence/Premium/Avenir has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Accord doesn’t offer cornering lights.

A power rear sunshade is optional in the LaCrosse to help block heat and glare for the rear passengers. The Accord doesn’t offer a rear sunshade.

The LaCrosse’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Honda only offers heated mirrors on the Accord Sport 2.0T/EX/EX-L/Touring.

The LaCrosse Sport Touring/Essence/Premium/Avenir has standard automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Accord offers an automatic rear view mirror, but its side mirrors don’t dim.

On extremely cold winter days, the LaCrosse Premium/Avenir’s standard heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Accord doesn’t offer a heated steering wheel.

Both the LaCrosse and the Accord offer rear vents. For greater rear passenger comfort, the LaCrosse has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Accord doesn’t offer rear air conditioning vents, only heat vents.

The LaCrosse Premium/Avenir has a 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Accord doesn’t offer a house-current electrical outlet.

The LaCrosse Premium/Avenir’s optional Automatic Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Accord doesn’t offer an automated parking system.

Economic Advantages

Insurance will cost less for the LaCrosse owner. The Car Book by Jack Gillis rates the LaCrosse with a number “5” insurance rate while the Accord is rated higher at a number “8” rate.

According to The Car Book by Jack Gillis, the LaCrosse is less expensive to operate than the Accord because typical repairs cost much less on the LaCrosse than the Accord, including $388 less for a muffler, $86 less for a starter, $274 less for fuel injection and $88 less for a fuel pump.
