The best and worst Buick Lacrosse years, by the numbers
Short answer: among Buick Lacrosses old enough to judge (2005–2019), the 2014–2015 and 2018–2019 have the fewest owner complaints per 10,000 sold. The 2006–2009 have the most.
We counted every owner complaint filed with the federal government (NHTSA) for each model year and divided by how many were sold that year, so a year that sold more doesn’t look worse just for being popular. Years newer than 2019 are shown but not ranked — they haven’t been on the road long enough. How this is calculated.
