The LaCrosse is a sophisticated and thoroughly modern sedan. Quiet, roomy and luxurious, it offers responsive handling and a steady ride, qualities not normally associated with past Buicks. However, the cockpit is a bit narrow, the dashboard is busy, and styling restricts visibility and access. The 2.4-liter four-cylinder is mated to a light hybrid system.

Road Test Results

Performance
Acceleration Acceleration Acceleration tests are conducted on a smooth, flat pavement straightaway at the track. Time, speed, and distance measurements are taken with a precise GPS-based device that’s hooked to a data-logging computer.
0 to 60 mph 0 to 60 mph (sec.) The time in seconds that a vehicle takes to reach 60 mph from a standstill with the engine idling.
Transmission Transmission Transmission performance is determined by shifting smoothness, response, shifter action, and clutch actuation for manual transmissions.
Braking Braking The braking rating is a composite of wet and dry stopping distances and pedal feel. Braking distance is from 60 mph, with no wheels locked.
Emergency Handling Emergency Handling Several factors go into the rating, including the avoidance maneuver speed and confidence, as well as how the vehicle behaves when pushed to its limit.
Comfort / Convenience
Ride Ride Our expert judgment of how well the suspension isolates and absorbs road imperfections and how steady it keeps the body on various road surfaces.
Noise Noise Our expert judgment of the vehicle's interior noise level in everyday driving.
Front Seat Comfort Front Seat Comfort Our judgment of how comfortable the front seat is for drivers of various heights.
Rear Seat Comfort Rear Seat Comfort Our judgment of how comfortable the rear seat is for two passengers to sit across.
Interior Fit and Finish Interior Fit and Finish An expert evaluation of the interior quality and craftsmanship.
Trunk/Cargo Area Trunk/Cargo Area Our rating is based on the amount of luggage or cargo space that a vehicle has in the trunk or cargo area.
Fuel Economy & Emissions
Fuel Economy Fuel Economy We perform our own fuel-economy tests, independent of the government's often-quoted EPA figures and the manufacturers' claims. Using a precise fuel-flow measuring device spliced into the fuel line, we run two separate circuits to represent city and highway consumption.
CR's Overall Mileage CR's Overall Mileage CR's overall mileage is a composite of measured fuel usage on a prescribed city course and highway cruising; and CR's 150-mile test trip of mixed driving, if tested. In recent road tests, we've discontinued the 150-mile trip test.
CR's City Mileage CR's City Mileage Measured fuel usage on a prescribed city course.
CR's Highway Mileage CR's Highway Mileage Measured fuel usage on a prescribed highway cruising.
Annual Fuel Cost Annual Fuel Cost The cost and amount of fuel used in 12,000 miles and is calculated from CR's overall mileage.
Greenhouse Gas Greenhouse Gas The Greenhouse Gas Rating represents the amount of carbon dioxide the vehicle emits compared to other vehicles of the same model year. This score from the EPA ranges from 1 (worst) to 10 (best).
Smog Rating Smog Rating The Smog Rating represents the amount of health-damaging and smog-forming airborne pollutants the vehicle emits compared to other vehicles of the same model year. This score from the EPA ranges from 1 (worst) to 10 (best).

Owner Reports

Reliability History Reliability History The reliability charts are based on responses on hundreds of thousands of vehicles from our latest Annual Auto Survey. Consumer Reports subscribers reported on any serious problems they had with their vehicles during the past 12 months that they considered serious because of cost, failure, safety, or downtime, in any of the trouble spots included in the table below. The results are presented relative to the average model that year. Extra weight is given to the more serious areas such as major engine or transmission problems. Based on this data and further analysis, we predict reliability for the latest year. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Owner Satisfaction Owner Satisfaction To learn about satisfaction, CR has collected survey data from our annual survey on more than half a million vehicles. Our subscribers provide great insights into their satisfaction by answering one simple question: If they had it to do all over again, would they definitely buy or lease the same model? In addition, respondents also rate their cars in six categories: driving experience, comfort, value, styling, audio, and climate systems. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Road Test

The LaCrosse is a sophisticated and thoroughly modern sedan. Quiet, roomy and luxurious, it offers responsive handling and a steady ride, qualities not normally associated with past Buicks. However, the cockpit is a bit narrow, the dashboard is busy, and styling restricts visibility and access.

The 2.4-liter four-cylinder is mated to a light hybrid system. This has good acceleration, while returning an impressive 26 mpg overall. The refined 3.6-liter V6 is smooth and delivers plenty of power.

Sensors (includes O2 or oxygen sensor)

"SES light was on. Installed new purge solenoid to correct issue."

J H., MI (2015 Buick LaCrosse 3.6-L V6)

"Within a year of purchase, the check engine light illuminated. Under warranty, the tech reset the sensor and said that this was likely due to weather change. Within six months, it occurred again, and because of my excessive mileage, it ws no longer under warranty and I was told that the C02 sensor was bad and required replacement (my cost). 4-5 months later, same thing, and I was advised to get an injection cleaning (over $170). Two months later, and the check engine light is on more than it is off. The frustration of the cost is exacerbated by the time lost constantly taking the vehicle back to the service department."

Paint/Trim

What Owners Say

Loose interior trim or moldings

"This is related to the material that surround the circular up/down/left/right arrows on the right side of the steering column. After a few months of delivery, I noticed what appeared to be a slight bubble in th plastic. It was not large, so I didn't give it too much thought. In hindsight, given the 50,000 mile warranty and the 32,000 miles I drive per year, I should have taken it in right away. One day, I saw that the material had cracked, exposing an area of white plastic underneath. I have owned both expensive and inexpensive vehicles since the 1970's, and even the most inexpensive of my vehicles did not have these kinds of problems. The dealer advised me that at two years but at over 60,000 miles, my warranty had expired due to mileage, and they could repair it for around $190. Understanding that legally they are not bound to address the issue, but noting that mileage obviously has nothing to do with interior trim, I asked them if this might be an exception? It was not. In the end, I paid for a mid-level luxury vehicle that had interior trim being to deteriorate immediately."
