The 2017 to 2019 Buick LaCrosse received five-star ratings across all NHTSA crash-test categories for US-market vehicles. The sedan earned five stars in frontal crash, side crash, rollover, and side pole tests. NHTSA maintains these ratings across model years until a vehicle redesign occurs, so this five-star rating applies to the entire 2017 to 2019 range covered by this assessment.
5/5 Overall
NHTSA 5-Star Safety Rating
The 2019 Buick LaCrosse has two recalls, the more serious being a transmission issue where missing bolts on the start-stop accumulator can cause a transmission fluid leak that may progress to a complete loss of drive power.
The second recall involves the rear brake calipers, where the pistons may have an insufficient coating that allows gas pockets to form inside, reducing rear braking performance and raising the risk of a crash.
