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.

Exhaust system. Catalytic converter. Smell of sulfur/rotten eggs when accelerating especially going up a hill. Took car to dealer and they replaced catalytic converters. A few months later the problem persists. It seems now it does this more often.

4Runner 4WD 6-cyl

  • Automatic transmission
  • 1,200 miles
I recently purchased a new 2006 Toyota 4 runner. I have had nothing but motor transmission, electrical failures. I have only had my vehicle for 1 month and anything and every thing has gone wrong. I even had to give my daughter cpr on the side of the road due to carbon monoxide inhalation. She went into respiratory failure do to this she has severe asthma.
