Buick LaCrosse: A Comprehensive Guide
The Buick LaCrosse is a full-size/mid-size sedan that offered a blend of comfort, style, and value. Spanning multiple generations, it served as Buick's flagship sedan for many years, appealing to buyers looking for a more refined and spacious alternative to mainstream offerings. It occupied the space between premium and luxury, often compared with models from Lexus and Acura.
Generations of the Buick LaCrosse
- First Generation (2005-2009): Introduced as a replacement for the Century and Regal. Offered with a variety of V6 engines. Focused on traditional Buick values: quietness, comfort, and ease of driving. Known internally as the "G Platform."
- Second Generation (2010-2016): A significantly more stylish and modern redesign. Offered in front-wheel drive and all-wheel drive configurations. Introduced more advanced technology and safety features. Considered a significant step up in terms of design and quality compared to the first generation. Featured the eAssist mild hybrid system in later years.
- Third Generation (2017-2019): The most contemporary and technologically advanced LaCrosse. Further refined design, improved fuel efficiency, and enhanced driving dynamics. Featured a new 9-speed automatic transmission in later models. Unfortunately, this was the last generation of the LaCrosse, as Buick discontinued it after the 2019 model year.
Reliability & Common Issues
The Buick LaCrosse, across its generations, has generally demonstrated average to above-average reliability, though specific issues vary by model year and engine choice. Here's a breakdown:
First Generation (2005-2009)
- Intake Manifold Gasket Leaks (3.8L V6): A common issue in older 3.8L V6 engines. Symptoms include coolant loss and overheating. This is a relatively common and well-documented problem.
- Transmission Issues (4T65E): The 4T65E transmission, used in many first-generation LaCrosse models, can experience shifting problems and premature failure. Regular fluid changes are critical.
- Electrical Problems: Some owners have reported issues with power windows, door locks, and other electrical components.
Second Generation (2010-2016)
- Timing Chain Issues (3.6L V6): The 3.6L V6 engine is generally reliable, but some models have experienced timing chain wear and stretching, particularly if maintenance schedules are neglected. Listen for rattling noises on startup.
- Water Pump Failure (3.6L V6): Another potential issue with the 3.6L V6 is water pump failure. Look for coolant leaks.
- eAssist System (2012-2016): Models equipped with eAssist, while increasing fuel economy, have unique components that can require specialized service. Battery issues and hybrid system malfunctions can occur, although not extremely common.
- Infotainment System Issues: Some owners have reported glitches and problems with the MyLink infotainment system.
Third Generation (2017-2019)
- Transmission Issues (9-Speed Automatic): While generally reliable, some owners reported issues with the 9-speed automatic transmission, particularly in early production models. This can include rough shifting and hesitation.
- Electronic Issues: Similar to the previous generation, the infotainment system and other electronic components can experience glitches.
- Oil Consumption (2.5L 4-Cylinder): Some reports of increased oil consumption on the 2.5L 4-cylinder engine, though not as widespread as on some other GM vehicles.
General Recommendations: Regardless of the generation, a thorough pre-purchase inspection by a qualified mechanic is highly recommended. Check for any signs of fluid leaks, unusual noises, and ensure all electronic systems are functioning correctly. Review the vehicle's maintenance history to determine if regular servicing has been performed.

Buying Advice
Here's some advice to help you choose the right Buick LaCrosse:
- Best Years: The 2017-2019 models (third generation) offer the most modern features, styling, and technology. However, they are also the most expensive. 2014-2016 models offer a good balance of features, reliability, and value.
- Years to Avoid (Potentially): Early model years of the first generation (2005-2006) might be more prone to the intake manifold gasket issues. Early years of the 9-speed transmission (2017) might be slightly more prone to transmission issues, but by no means a reason to avoid these models outright.
- Engine Choice: The 3.6L V6 engine is generally a good choice, offering a good balance of power and reliability. Just be aware of potential timing chain and water pump issues, especially on higher-mileage examples. The 2.4L eAssist is fuel efficient, but may require specialized repairs if issues arise.
- Consider Options: Higher trim levels offer more features and luxury, but also command a higher price. Leather seats, navigation, and advanced safety features are worth considering if they fit your budget.
- Check the Vehicle History: Always obtain a vehicle history report (Carfax or AutoCheck) to check for accidents, title issues, and maintenance records.
- Pre-Purchase Inspection: Have a qualified mechanic inspect the vehicle before you buy it. This can help you identify any potential problems and avoid costly repairs down the road.
The Buick LaCrosse represents a comfortable and stylish option in the sedan market. With careful research and a thorough inspection, you can find a well-maintained example that will provide years of enjoyable driving.
