TRACTION CONTROL LIGHT CAME ON, CHECK ENGINE LIGHT CAME ON AND VEHICLE WOULD MOVE ONLY SLOWLY. TURNED CAR OFF AND ON SEVERAL TIMES, TRIED ENGAGING 4 WHEEL DRIVE AND OTHER DRIVE FUNCTIONS, TRIED ACCELERATING, BUT VEHICLE WOULD ONLY MOVE SLOWLY. AFTER TURNING OFF AND ON ONE MORE TIME THE VEHICLE DROVE AS NORMAL BUT ALL THE WARNING LIGHTS STAYED ON. THIS HAPPENED IN A PARKING LOT WHILE GOING SLOWLY. MECHANIC HAS INDICATED THAT THIS RESULTED FROM A FAILURE OF THE AIR INJECTION PUMP AND AIR VALVE, WHICH APPARENTLY FOR SOME REASON TURNS OFF TRACTION CONTROL. THIS IS A COMMON ENOUGH PROBLEM ON TUNDRAS AND SEQUOIAS THAT THERE IS AN "EXTENDED WARRANTY" OFFERED ON THESE VEHICLES. I DO NOT KNOW IF THE AIR INJECTION PUMP AND AIR VALVES ON 4 RUNNERS ARE THE SAME DESIGN OR SAME MODEL, BUT THERE ARE NUMEROUS COMPLAINTS ON THE INTERNET OF THE SAME PROBLEM FOR 4 RUNNERS AS FOR TUNDRAS. *TR

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. I BELIEVE THERE SHOULD BE A RECALL ON THIS SYSTEM OR AT LEAST HAVE TOYOTA COVER ALL VEHICLES WITH THIS DEFECTIVE SYSTEM, NOT JUST CERTAIN HIGHER-VOLUME MODEL YEARS. *TR

2006 TOYOTA 4RUNNER. I WAS QUOTED $1,500 FOR A TIME COVER OIL LEAK REPAIR IN LAKELAND, FL. THERE WAS A TSB ISSUED 2007 (EG049-07). APPARENTLY, MOST OF THE CHARGE IS FOR LABOR, THE REPLACEMENT PART IS NOT EXPENSIVE. I UNDERSTAND THE AVALON HAS THE SAME PROBLEM. THIS REPAIR COST IS ASTRONOMICAL, ESPECIALLY CONSIDERING THAT IT'S A COMMONLY KNOWN PROBLEM IN TOYOTAS - POSSIBLY FROM POOR DESIGN. I DON'T THINK THE CONSUMER SHOULD HAVE TO ABSORB THE COST OF THIS REPAIR. HOPEFULLY, SOMETHING IS BEING DONE TO HELP THE CONSUMER. *TR

EXHAUST IS BEING PULLED INTO BACK WINDOW WHEN CRACKED AND THE VEHICLE RESETS THE AIR FLOW TO RECYCLE. I CRACK THE BACK WINDOW TO ALLOW HEAT TO ESCAPE AND HAD THE AIR FLOW SET ON FRESH AIR. I MAKE A STOP AND GET BACK INTO THE CAR THE WINDOW IS STILL CRACKED. SOME TIME LATER THERE IS A SMELL OF EXHAUST AND I REALIZE THE FLOW WAS RESET AND FUMES ARE GETTING PULLED INTO THE VEHICLE. THE BIGGEST PROBLEM IS MY CHILD IS IN THE BACK SEAT AND SHE IS ALREADY CHOKING WHEN THE ODOR GETS TO ME. *TR
