Summary

The 2020 Toyota 4Runner is generally a reliable vehicle, but owners have reported issues ranging from minor electrical glitches to more significant mechanical problems. Engine and transmission issues are relatively uncommon, but some owners have experienced valve cover gasket leaks and transmission shifting issues. Electrical problems, particularly with the Entune system and TPMS, are more frequently reported. Suspension issues, such as leaking struts, may require attention. Addressing these issues promptly can help maintain the 4Runner’s reliability and longevity. While some repairs may be relatively inexpensive, others can be costly, especially if involving transmission work.
