Is the 2010 Buick LaCrosse Worth Buying?
The 2010 Buick LaCrosse offers a comfortable ride and premium feel at an accessible price point, making it a compelling choice for many buyers. However, its reliability is hampered by a few significant known issues, particularly with the 3.6L V6 engine's timing chain and certain transmission components, demanding careful inspection and potentially leading to costly repairs. While generally a solid sedan, you must proceed with caution to ensure you're not inheriting a ticking time bomb.
The 2010 Buick LaCrosse is a comfortable and stylish sedan that offers a lot of value. However, the pervasive and expensive timing chain issues on the 3.6L V6 engine, coupled with potential transmission and electrical quirks, mean a purchase requires extreme vigilance. If you find a well-documented 3.0L V6 model wit…
Best Model Years
For this generation (2010-2016), models post-2012 with the revised 3.6L V6 (if timing chain replaced) or those equipped with the 3.0L V6 (if available) are generally preferred.
Years to Avoid
Be especially wary of 2010-2012 models equipped with the 3.6L LF1/LLT V6 engine, unless there is clear documentation of timing chain service or a comprehensive pre-purchase inspection comes back flawless.
Biggest Strengths
- Smooth, quiet ride quality for long-distance comfort
- Spacious and well-appointed interior for its class
- Generally robust body structure and braking system

2010 Buick LaCrosse Recall History
2 recalls on record from NHTSA. Check your VIN atnhtsa.gov to see if the repair was performed.
SUSPENSION:REAR
General Motors, LLC (GM) is recalling certain 2012-2013 Buick Regal, 2013 Chevrolet Malibu, and 2010-2013 Buick Lacrosse vehicles sold or ever registered in Connecticut, Delaware, the District of Columbia, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, or Wisconsin. These vehicles may have rear toe links that received excessive electrocoating (e-coat) corrosion protection, which could cause the e-coat to become brittle and break away when contacted by road debris. Over time, the e-coat may chip away, exposing the metal toe link and making it more susceptible to corrosion. Corrosion may eventually cause the toe link to thin and ultimately to fracture.
