Buick LaCrosse — the 10 years we've written up
2010–2019, side by side: what goes wrong on each, what the fix costs, and what they typically ask. 10 of the 10 carry a high-severity issue.
What this page is
These are the 10 Buick LaCrosse model years Kestrel has done the homework on — not every year Buick built one. A year that isn't listed here isn't a year we're warning you off; it's one we haven't written up yet. Ranking a whole model run would mean telling you about years we've never looked at.
Buick LaCrosse by year
How many owner complaints NHTSA holds. A big number usually means a lot were sold; the shape matters more than the total.
Year by year
Stop/start transmission accumulator may be missing its endcap bolts — fluid leak, then loss of drive (recall) — $0 with the recall — verify it was performed
High-pressure fuel pump can detach and leak fuel — fire risk (recall) — $0 with the recall — verify it was performed

This page covers the Buick LaCrosse in general. The Kestrel report covers the one you're looking at — the asking price against the market, the photos, the seller's description, and a BUY / NEGOTIATE / WALK AWAY verdict with a negotiation script.
