I CAME HOME FROM WORK AND REVERSED MY 4RUNNER INTO MY GARAGE AS I NORMALLY DO. THE NEXT MORNING, MY 4RUNNER STARTS AND THE ENGINE SOUNDS NORMAL BUT IT WON'T MOVE WHEN I SHIFT THE GEAR FROM PARK TO DRIVE. I STEPPED ON THE GAS WHILE LEAVING THE GEAR IN DRIVE, THE RPM MOVES BUT THE 4RUNNER STAYED IN THE SAME SPOT. *TR
MULTIPLE TIMES NOW WHILE DRIVING UNDER NORMAL CONDITIONS WE HAVE EXPERIENCED THE INSTRUMENT PANEL GOING ROGUE. ABS, VSC, GAS, CHECK ENGINE, ALL LIGHTS WILL RANDOMLY COME ON. THE SCARY PART IS THIS MOST RECENT TIME IT JUMPED THE SPEEDOMETER WAY UP AS WELL. ANY HELP WOULD BE GREATLY APPRECIATED!
NEEDED TO USE MY HORN WHEN SOMEONE DRIFTED INTO MY LANE ON THE INTERSTATE. THE HORN DID NOT WORK. I COULD NOT HONK TO INFORM THAT DRIVER TO STAY IN HIS/HER LANE. AFTERWHICH, I TOOK IT TO MY TOYOTA DEALER. THEY DIAGNOSED AND DISCOVERED THE SPIRAL CABLE HAD AN OPEN CIRCUIT. THEY REPLACED THE SPIRAL CABLE ASSEMBLY. FROM WHAT I REMEMBER THEY TOLD ME THIS CABLE ASSEMBLY CARRIED WIRING FOR CRUISE CONTROL, AIR BAGS, HORN AND SOMETHING ELSE. I DO NOT RECALL THE FOURTH ITEM.
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. THE FACT THAT THIS COMPONENT FAILED AFTER A SHORT DURATION IN SUCH A SUDDEN AND VIOLENT WAY IS VERY DANGEROUS. 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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
NOT SURE. WIFE WAS DRIVING 2015 4RUNNER INTO PARKING LOT AT LOW SPEED AND IT JUMPED A TREE. NOT AT ALL SAYING IT IS A TOYOTA ISSUE - JUST TO BE ON SAFE SIDE REPORTING. AIR BAGS DID NOT DEPLOY. UNDERSTANDING IS IT JUST ENDED UP THERE WHEN SHE WAS PARKING. EPIC PHOTO - ALL THE SAME - WORTH DOCUMENTING. SHE ADVISED SHE WAS STOPPED OR JUST STOPPED PRIOR TO THE TREE-CLIMB. PAX SIDE WAS DAUGHTER AND TAKING HER IN FOR MEDICAL TODAY DUE TO COMPLAINTS OF PAIN AND WEAKNESS. POLICE CAME BUT DID NOT ISSUE REPORT.
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 ...
I HAD 20,000 MILES AND BOUGHT THE VEICHLE BRAND NEW AND WENT TO LEAVE WORK AND MY VEICHLE WAS STRUGGLING TO STAY GOING AND MY CHECK ENGINE LIGHT WAS FLASHINING. WHEN I'D GO TO REVERSE THE VEHICLE WOULD STRUGGLE AND ACT LIKE IT WAS GOING TO DIE. I HAD TO GO 20MPH ON THE SIDE ROADS ABOUT 15 MILES TO THE DEALER. THE RPM SHOULDN'T SHIFT. IT WAS CAUSED BY A MOUSE I GUESS? SINCE THEY USE SOY BASE AND SEE THIS A LOT. SO FUSTRATING WHEN YOU PAY $38,000 FOR A VEICHLE. I'D MUCH RATHER DRIVE MY OLDER 2010 HONDA THAT NEVER HAD AN ISSUE WITH SO CALLED A MOUSE. THEY OF COURSE WOULDN'T COVER IT. TO TOP IT OFF I HAD A MAJOR OIL LEAK AT 19,000 MILES CAUSING ABOUT $6,000 WORTH OF DAMAGE. WHICH WAS THE FACTORY'S FAULT THEY SAID. IT WAS COVERED BY WARRENTY, BUT STILL IT'S RIDICULOUS. I BOUGHT THE CAR NEW. WITH 1 MILE ON IT, FRESH OFF THE TRUCK. AS OF RIGHT NOW I HAVE NO FAITH IN TOYOTA. I'M AFRAID MY VEICHLE WILL BREAK DOWN ON ME. WHICH I SHOULDN'T HAVE TO FEEL WHEN I BUY A NEW CAR. SO DISAPPOINTED IN TOYOTA. SOMETHING NEEDS TO BE DONE.

SEPARATE INCIDENT SAME DAY BACKING OUT OF PARKING SPOT WENT INTO TRACTION CONTROL MODE WITH BRAKES VIBRATING AND CLICKING ON DRY PAVEMENT. *TR
MY FIANCE WAS DRIVING OUR DAUGHTER TO PRESCHOOL. SHE WAS PULLING INTO A PARKING SPACE TO HER RIGHT. SHE STOPPED FOR SOME PEDESTRIANS RIGHT BEFORE PULLING IN. TOOK HER FOOT OFF THE BRAKE AND THE CAR SUDDENLY ACCELERATED INTO THE FENCE IN FRONT OF THE PARKING SPACE. *TR
