What owners wrote

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.

Reported at 1,200 miles, March 2006 Injury

The secondary air induction pump (aip) and switching valves failed on my 2006 4runner limited with v8. This is the same issue that is seen on toyota sequoias and tundras. Toyota has issued a special extended warranty for this system on those vehicles, but not on the 4 runners, even though the defective systems / parts are the same. Toyota customer case # 1409160408. This is a > $2000 repair to basically clear the check engine code and allow me to pass state inspection.
