Summary

The 2011 Toyota 4Runner is generally a reliable vehicle, but owners should be aware of potential issues, particularly with the secondary air injection system and X-REAS suspension if equipped. Frame rust is also a significant concern, especially in regions with harsh winters. Repair costs can range from a few hundred dollars for minor issues to several thousand for more extensive problems like frame repair or X-REAS replacement. While some issues are more prevalent than others, proper maintenance and regular inspections can help mitigate the risk of major repairs.
