Overview

2021 Toyota 4Runner

The 2021 Toyota 4Runner presents itself as a rugged, body-on-frame SUV with a reputation for durability. However, a closer look at owner complaints reveals a few key areas that warrant attention for used-car shoppers. While its overall reliability is rated as 'Good,' the prevalence of steering and suspension shimmy issues, alongside reports of service brake problems, suggests these components require careful scrutiny. The 4.0-liter V6 engine paired with a 5-speed automatic transmission delivers adequate power, though fuel economy is modest at 17 MPG combined. Safety ratings are solid, with an overall 4-star score from NHTSA, though the rollover rating is a less impressive 3 stars. With 49 complaints logged, the most frequent concerns revolve around steering, suspension, and service brakes, with some critical failures noted.

Critical Failure Risk

A persistent shimmy or shake at highway speeds (55-70 mph) is the most reported issue. This can be caused by tire imbalance, alignment issues, or worn suspension components.

Early detection can help you avoid a $500-$5,000 repair.
