Notes: Although it has a stellar record in terms of vehicle problems, initially the 4th generation (2003 - 2009) 4Runner didn't earn our top "Seal of Awesome" rating because it received poor crash test ratings for rear impacts. However it's proven to have one of the lowest driver death rates out of all vehicles (not just SUVs), so we've bumped it back up to our top award.

2006 Toyota 4Runner Owner Comments

problem #2

4Runner 4WD 6-cyl

  • Automatic transmission
  • 500 miles


Toyota 2006 4runner 4WD limited discharges a sulfur smell when I accelerate, especially when I am going up a hill. The smell is strong even when my windows are up. I'm also concerned about the smell being a health issue. I purchased the car brand new in February 2006.

4Runner 8-cyl

  • Automatic transmission
  • 5 miles
When my 2006 Toyota 4runner is running or when acceleration a rotten egg smell comes from the catalytic converter. I have taken the vehicle in and the dealer claims there is nothing they can do. I have never had this problem on any other vehicles I have owned.
