Product Reviews

Welcome to Consumer Reports.

We’re so glad to have you as a member. You now have access to benefits that can help you choose right, be safe and stay informed.
The LaCrosse is a sophisticated and thoroughly modern sedan. Quiet, roomy and luxurious, it offers responsive handling and a steady ride, qualities not normally associated with past Buicks. However, the cockpit is a bit narrow, the dashboard is busy, and styling restricts visibility and access.
