NHTSA 5-Star Safety Rating
Electrical and powertrain complaints lead the 2017 Buick LaCrosse owner reports, with suspension close behind. On the electrical side, owners describe a range of system failures, an intermittent airbag warning light that required dealer reprogramming, and an amplifier failure that knocked out not just audio but also chimes for seatbelt reminders, door alerts, backup warnings, and other vehicle notifications. Powertrain complaints center on shuddering and abnormal noises during driving. Suspension reports focus on the front strut assembly, with owners describing loud stomping sounds, wheel shudder, and increased steering effort, one recurring theme is that replacement parts for the front suspension have become difficult or impossible to source, leaving owners unable to complete repairs or get a proper wheel alignment, which some say leads to accelerated and uneven tire wear.

Total Complaints
By System
The 2017 Buick LaCrosse has 4 recalls, the most serious involving rear suspension toe-links that may have been installed backwards, causing the outboard bolt to work loose and the link to separate from the suspension, which can result in a loss of vehicle control.
The remaining two recalls both concern the electric power steering system and describe the same underlying issue: the electrical connectors may not be properly sealed, allowing water to enter and corrode the connections. This can cause the power steering assist to cut out intermittently or fail entirely, leaving the driver with significantly heavier steering effort and a higher risk of losing control, particularly at lower speeds or during turns.
