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 4Runner remains a sound choice among midsized SUVs, especially with its available stability-control system. The pickup-truck ancestry is still apparent though in its jittery ride, tight cockpit, high floor and low roof. On the other hand, improved emergency handling and capable off-road ability do help offset those flaws.
