Open the full vehicle complaint log (all categories)I HAVE A 2015 4RUNNER (VIN: [XXX]) I PURCHASED BRAND NEW. IT CURRENTLY HAS LESS THAN 50K MILES ON IT. A FEW WEEKS AGO IT STARTED PERIODICALLY GOING INTO ?LIMP? MODE WHILE DRIVING AT HIGHWAY SPEEDS. MY TWO TODDLERS WERE IN THE VEHICLE THE FIRST TIME THIS HAPPENED; I ALMOST LOST CONTROL SINCE THE ?TRACTIONAL CONTROL? DISABLED CONCURRENTLY. I TOOK THE VEHICLE TO MULTIPLE MECHANICS WHO CONFIRMED THE DIAGNOSTIC CODE P2445 (SECONDARY AIR INJECTION PUMP). I WAS SHOCKED TO HEAR THIS BECAUSE THE VEHICLE IS RELATIVELY NEW AND EXCEPTIONALLY WELL MAINTAINED. I LOOKED ONLINE AND THE FAILURE OF THIS COMPONENT APPEARS TO BE A SYSTEMIC ISSUE WITH TOYOTA 4RUNNERS AND TACOMAS.

I SUBMITTED A FORMAL COMPLAINT TO TOYOTA AND THEY DENIED KNOWLEDGE OF THIS ISSUES DESPITE HUNDREDS OF FOLKS REPORTING IDENTICAL PROBLEMS ON THEIR 4RUNNERS & TACOMAS. FOR A NOMINAL FEE PER VEHICLE TOYOTA COULD FIX THIS ISSUE, WHICH ALSO HAS ENVIRONMENTAL IMPLICATIONS, BUT INSTEAD THEY ARE BEING DISINGENUOUS AND DENYING THIS MAJOR SYSTEMIC SAFETY HAZARD.

WHEN ACCELERATING THROUGH A TURN FROM A STOP, IF FOR ANY REASON YOU LIFT OFF THE ACCELERATOR PEDAL AND THEN REAPPLY PRESSURE TO THE ACCELERATOR PEDAL, NO ACCELERATION TAKES PLACE. IT IS IF YOU ARE NOT PRESSING THE ACCELERATOR AT ALL, NO MATTER HOW HARD YOU PRESS. THIS HAS ALMOST RESULTED IN SEVERAL COLLISIONS BECAUSE THE CAR IS NO LONGER ACCELERATING AND IS JUST COASTING. TO CORRECT THIS CONDITION, YOU HAVE TO COMPLETELY LEFT YOUR FOOT OFF THE ACCELERATOR AND REAPPLY PRESSURE. SOMETIMES YOU HAVE TO DO THIS MORE THAN ONCE. VERY DANGEROUS. I REPORTED THIS TO MY TOYOTA SERVICE REP, AND HE SAID HIS DOES THE SAME THING. IT COULD BE THE THROTTLE POSITION SENSOR, OR FOUR WHEEL DRIVE SOFTWARE, OR ...
