Watch out for

Reputation: what owners and the press report. Tap one to see what to check.

  • Frame rust All years Walk away if found

    What to check: Inspect the frame and the front lower control arm mounts.

    NHTSA found 15 complaints of control arm failure, 13 from road-salt states, and denied a defect petition in 2022. A class action over 2005 and later trucks was dismissed in 2023.

  • Timing belt and water pump V8

    What to check: Ask for records.

    Due every 90,000 miles or 7 years.

    Sources 12,4

  • Cracked exhaust manifolds V8

    What to check: Listen for a ticking noise.

    Sources 4,12

  • Head gasket V6, 2003–2005 One source so far

    What to check: Watch for a misfire at cold start, most often on cylinder 6.

    Three owners of 2004 V6s in one thread report head gasket leaks at about 150,000 to 210,000 miles, without overheating. Members disagree on the cause: some blame past overheating, others the design.

    About $2,000 in labor

  • Cracked dashboard 2003–2005 One source so far

    What to check: Look for cracks.

    Toyota's replacement program ended May 31, 2017.

  • X-REAS shock leaks Sport Edition. Optional on SR5 and Limited One source so far

    What to check: Look for oil weeping at each shock.

    Five owners in one thread report leaks in the X-REAS system, at about 50,000 to 66,000 miles where they say. A moderator notes the system is sealed and cannot be recharged.

    About $2,000 to replace. Four standard shocks cost one owner $289

  • 4WD actuator 4WD trucks One source so far

    What to check: Confirm it shifts into low range. Look for seepage at the actuator beside the transfer case.

    Two members in one buyer's-advice thread say to check it. One warns that an unused actuator can seize and is costly to fix, and the other calls a leak there a reason to walk away.

  • Rear air suspension Some Limited trucks One source so far

    Two members in one thread warn that the rear air bags are vulnerable: one to damage off-road, the other to wear when the truck is lifted. Neither reports a failure of their own. The thread gives no check.

What buyers say

Reputation: what owners and the press report

  • Sought after: V8 All years One source so far

    The only 4Runner generation with a V8. Enthusiasts are said to seek out a clean one.4

  • Avoid: Frame rust All years Walk away

    Both generations rust at the frame, worst where roads are salted, and rust can leave a frame unsafe. Toyota's frame rust program for its trucks did not include the 4Runner.18,19,4,10,11

  • Avoid: 2003–2005 V6 2003–2005 Less sought after One source so far

    Members of one thread split. Four steer buyers away from 2003–2005 V6s or shop only 2006 and later, while five owners of 2003–2005 V6s report no head gasket trouble, one at about 303,000 miles.20
