My truck started having a vibration when driving around 45-55 mph. This problem first became noticeable when it had about 115,000 miles on it. Over time the speed that the vibration became noticeable at gradually increased. By 125,000 miles on the truck, it was vibrating hard between 60 and 70 mph. The dealership determined that the problem was that the drive shaft was out of balance and that it had to be replaced. They replaced the drive shaft, but this doesn't seem like a problem that should creep up with that relatively few miles on the vehicle, and I have read that if the drive shaft actually fails, it can severely damage the vehicle and potentially cause injury.

DURING NORMAL DRIVING, THE CHECK ENGINE LIGHT AND TRACTION CONTROL OFF LIGHT CAME ON AND TRUCK IMMEDIATELY WENT IN TO LIMP-HOME MODE. I HAD IT SCANNED FOR CODES AT THE LOCAL AUTO PARTS STORE AND IT CAME BACK WITH P2440 AND P2442 WHICH SEEMS LIKE A COMMON ISSUE WITH A VALVE IN THE SECONDARY AIR INJECTION SYSTEM. I QUICK GOOGLE SEARCH SHOWED THAT SOME 2012 TACOMA OWNERS ARE GETTING THIS COVERED UNDER A SPECIAL WARRANTY EXTENSION, SO I PUTTERED OVER TO THE TOYOTA DEALERSHIP EXPECTING TO HEAR THE SAME STORY, BUT THEY ARE TELLING ME THE ECM COMPUTER IS BAD. WHICH I AM TRYING TO GET CLARIFICATION ON SINCE I CAN'T FIND ANY ECM FAILURE ISSUES FOR THIS MAKE AND MODEL YEAR.

THE FAILURE RECURRED SEVERAL TIMES AND THE VEHICLE WAS TAKEN BACK TO THE SAME DEALER. THE TECHNICIAN DIAGNOSED THAT THE CLUTCH NEEDED TO BE REPLACED.

CHECK ENGINE LIGHT AND TRAC OFF LIGHT CAME ON. TRUCK WENT INTO "LIMP" MODE AND WOULD ONLY GO ABOUT 35MPH. CHECKED THE ERROR CODE AND IT WAS P2442 WHICH SAYS THE SECONDARY AIR INJECTION SYSTEM IS FAILING. TRUCK HAS ONLY 55K MILES ON IT AND HAS BEEN REGULARLY MAINTAINED BY TOYOTA DEALERSHIPS EVERY 6 MONTHS / 5K MILES. DEALERSHIP HAS SAID IT WILL BE $2023 TO REPLACE THE SYSTEM. THERE SHOULD BE A RECALL OR EXTENDED WARRANTY ON THIS INJECTION SYSTEM

I START UP THE TRUCK AND PULL OUT IN TO THE STREET. WHETHER AT AN INTERSECTION OR MAKING A TURN, I PUSH ON THE ACCELERATOR AND NOTHING HAPPENS. THE RPMS DON'T INCREASE, ENGINE MAKES NO SOUND - AND I AM LEFT SITTING IN THE MIDDLE OF THE ROAD. I PUSH THE ACCELERATOR TO THE FLOOR AND EVENTUALLY THE ENGINE COMES TO LIFE AND THE TRUCK MOVES FORWARD. HAPPENS MORE OFTEN THAN NOT WHEN THE VEHICLE IS "COLD" - WITHIN THE FIRST 20-30 MINUTES OF OPERATION. THE ACCELERATOR IS NOT LINKED DIRECTLY TO THE ENGINE THROUGH A CABLE BUT IS A DRIVE BY WIRE. I HAVE MAINTAINED MY TACOMA METICULOUSLY SINCE PURCHASE INCLUDING TUNE UPS, OIL CHANGES, ETC. I HAVE CLEANED THE MASS AIR FLOW SENSOR WITH NO CHANGE. THE PROBLEM STILL PERSISTS. IT IS VERY DANGEROUS TO BE IN THE MIDDLE OF AN INTERSECTION WITH A VEHICLE THAT HAS LOST POWER.

WHILE COMMUTING TO WORK THE ENGINE LIGHT AND TRACTION CONTROL LIGHT CAME ON, CAUSING MY TRUCK TO SLOW DOWN, VERY SLOW. IT WOULD NOT LET ME ACCELERATE AND DISABLED MY PROGRESS TO AROUND 2000 RPMS.

THE SECONDARY AIR INTAKE SYSTEM GOES OUT FAIRLY QUICKLY. MY VEHICLE IS AT 72,500 MILES. THIS CAUSES THE CAR TO GO INTO "LIMP" MODE WHICH MAKES THE CAR GO A MAXIMUM OF 40MPH.

NHTSA complaint #10960095 — an unverified report by a vehicle owner.

POWER TRAIN

CODE P2440 AND P2442. AIR INJECTION SYSTEM VALVES ARE STUCK OPEN (RELATED TO EMISSIONS CONTROL UNIT) WHICH CAUSES THE VEHICLE TO GO INTO 'LIMP' MODE ABRUPBTLY. THIS RENDERS THE VEHICLE UNDRIVEABLE, AND CAN OCCUR IN THE MIDST OF DRIVING CAUSING SERIOUS DANGER TO THE DRIVER AND FELLOW DRIVERS ON THE ROAD. TOYOTA IS UNWILLING TO COVER UNDER ANY POWERTRAIN OR EMISSIONS WARRANTY. THIS ISSUE IS PERVASIVE AMONG 2012 TACOMA OWNERS AND TOYOTA REDESIGNED THE SYSTEM AS EARLY AS 2013 WHICH IMPLICATES THEIR KNOWLEDGE OF SUCH A DEFECT.

2012 TACOMA WITH 37,00 MILES: WHILE LEAVING A PARKING LOT AND TRYING TO ACCELERATE ON TO A BUSY HIGHWAY, (60MPH SPEEDS), TRUCK WOULD NOT ACCELERATE AND "CHECK ENGINE" AND "TRAC OFF" LIGHTS ILLUMINATED. VEHICLE WENT INTO "LIMP MODE" AND WOULD NOT GO FASTER THAN 35 MPH. I HAD TO QUICKLY PULL OFF THE ROAD AS TO NOT CAUSE AN ACCIDENT. IF THIS HAD THIS OCCURRED WHILE TRAVELING AT NORMAL HIGHWAY SPEED (60 MPH+), WOULD DEFINITELY BE IN A WRECK DUE TO THE SUDDEN DOWNSHIFT AND DECELERATION. I TOOK VEHICLE TO LOCAL AUTO PARTS STORE AND RECEIVED THE CODE P2442: SECONDARY AIR INJECTION SYSTEM SWITCHING VALVE STUCK OPEN BANK 2. FROM RESEARCHING, THIS IS A KNOWN PROBLEM WITH 2012 TACOMAS, AND HAD PREVIOUSLY BEEN AN ISSUE WITH OLDER TUNDRAS, WHICH TOYOTA ISSUED A TSB FOR. TOYOTA REFUSES TO REPAIR THIS UNDER WARRANTY (EITHER POWERTRAIN OR FEDERAL EMISSIONS) EVEN THOUGH THE FAILED PART IS DIRECTLY TIED TO THE EMISSIONS SYSTEM! THE SYSTEM IS USED TO PUMP ADDITIONAL AIR INTO THE EXHAUST MANIFOLD UPON STARTUP TO DILUTE THE OVER-RICH CONDITIONS THAT LEAD TO INCREASED POLLUTION. (HOW IS THAT NOT AN EMISSIONS RELATED PART?) THE FAILURE OR WARPING OF THE ONE-WAY CHECK VALVE CAUSES HOT EXHAUST GASES TO BACKFLOW INTO THE SOLENOID, AND MELTING THE GASKETS. THIS ENDS UP BLOCKING THE SEALING PLATE AND CAUSING IT TO REMAIN IN THE OPEN POSITION. THE DANGER IS THAT THE HOT EXHAUST IS THEN FED INTO A PLASTIC AIR PUMP CAUSING IT TO POTENTIALLY MELT OR CATCH FIRE! THE FACT THAT THIS FORCES THE VEHICLE INTO "LIMP MODE" IS ALSO A HUGE SAFETY CONCERN AS IT WILL NOT ALLOW THE VEHICLE TO TRAVEL ABOVE 35 MPH AND COULD LEAD TO SERIOUS ACCIDENTS IF TRAVELING AT HIGH SPEED ON THE INTERSTATE OR HIGHWAY DUE TO THE UNEXPECTED, SUDDEN DECELERATION. FAILED ASSEMBLY IS TOYOTA PART NUMBER : 25710-31020. THIS PART NUMBER HAS BEEN SUPERSEDED BY P/N: 25710-31022 AND TOYOTA CHARGES BETWEEN $1500-$3200 TO REPLACE.

SECONDARY AIR INJECTION SWITCHING VALVE FAILURE STUCK IN OPEN POSITION CAUSING LIMP MODE IN THE TRUCK. TRUCK IS NOT ABLE TO GET TO SPEED ABOVE 40 MPH. THIS HAPPENED AS I WAS PULLING OUT OF MY NEIGHBORHOOD ONTO A STATE ROUTE WITH SPEED LIMIT OF 55 MPH AND CARS GOING WAY FASTER THAN THAT. THIS COULD POSE A DANGER IF SITUATIONS WHERE SPEED IT REQUIRED TO GET OUT OF THE WAY OF ANOTHER CAR. TRUCK ONLY HAS 57K MILES ON IT. THIS IS A SUPPLEMENTAL EMISSIONS SYSTEM AND SHOULD NOT CAUSE THE TRUCK TO BE USELESS IF FAIL.

MY 2012 TACOMA WITH 45,000 MILES GOT A CHECK ENGINE LIGHT AND "TRAC OFF" LIGHT WHEN I STARTED IT TO GO HOME. I WAS MERGING ONTO THE INTERSTATE AND UNABLE TO GO ABOVE 40 MPH. THIS WAS OBVIOUSLY NOT SAFE SO I EXITED AND TOOK IT TO A DEALER. THEY CITED TROUBLE CODES P2440 AND P2442 AND SAID THEY NEEDED TO REPLACE SECONDARY AIR INJECTION VALVE (PN 25710-31022) FOR A TOTAL COST OF $940! ACCORDING TO FORUMS AND THE NHTSA.GOV SITE, THIS IS A VERY COMMON COMPLAINT WITH THIS YEAR AND MODEL. I JUST BOUGHT THIS LAST JULY AND I NEVER EXPECTED TO HAVE TO REPLACE PARTS ANYTIME SOON.

AS I'VE READ FROM NUMEROUS OTHER 2012 TACOMA OWNERS ON TACOMAWORLD.COM, MY SECONDARY AIR INJECTION SWITCHING VALVE HAS FAILED AT 65K MILES. THIS SEEMS TO BE A RECURRING ISSUE WITH ALL 2012 SIMILAR TACOMA MODELS AND SHOULD ABSOLUTELY BE RECALLED AND REPLACED FOR FREE! UNTIL FIXED, MY TRUCK IS UNDRIVABLE, MEANING THE CEL LIGHT IS ON AND THE TRUCK WON'T GO FASTER THAN 30 MPH.

THIS DOESN'T HAPPEN ALL THE TIME BUT OCCASIONALLY WHEN THE TRUCK COMES TO A STOP AND THE BRAKE PRESSED THE VEHICLE WILL ACCELERATE WITH A SURGE AND FEEL LIKE SOMEONE HAS BUMPED YOU FROM BEHIND BUT THERE WILL BE NO ONE BEHIND YOU.

MY 2012 TACOMA IS NOT SHIFTING PROPERLY. IT IS SHIFTING VERY HARD AND A BIT ERRATIC WHEN DRIVING, AND WHEN I AM COMPLETELY STOPPED AT A LIGHT, THE TRUCK WILL SOMETIMES VIOLENTLY SURGE FORWARD MAKING IT FEEL LIKE ANOTHER VEHICLE HAS HIT ME FROM BEHIND. IT DOES NOT HAPPEN ALL THE TIME, BUT IT SEEMS TO HAPPEN MORE WHEN IT IS COLD. I TOOK IT TO THE DEALERSHIP ONLY TO BE TOLD THEY COULD NOT REPLICATE IT, AND THIS IS NORMAL FOR A TOYOTA. THE DEALERSHIP ALSO SAID THAT TOYOTA IS AWARE OF THIS, ALL TOYOTAS DO IT (EVEN THE BRAND NEW ONES), AND NOTHING CAN BE DONE. MY TRUCK IS STILL COVERED BY THE TOYOTA 5 YEAR WARRANTY AND THE LIMITED LIFETIME WARRANTY OFFERED FROM THE DEALER WHEN I PURCHASED IT. I FEEL LIKE THEY ARE NOT HONORING THEIR WARRANTY. IF THIS IS TRUE AND TOYOTA IS NOT CORRECTING THESE ISSUES, GUESS I WON'T BE BUYING THAT 2015 4-RUNNER I REALLY WANT!

I WAS APPROACHING A STOPLIGHT AT A DOWNWARD ANGLE AND WHILE APPLYING THE BRAKE THE VEHICLE BEGAN TO SHAKE VIOLENTLY. I WAS GOING APPROX. 15PMH WHEN IT STARTED AND IT DIDN'T STOP SHAKING UNTIL I GOT DOWN TO ABOUT 5 MILES PER HOUR. I TOOK IT TO THE DEALERSHIP THAT DAY AND EXPLAINED THE PROBLEM TO THEM. THEY GOT THE VEHICLE TO REPRODUCE THE VIBRATIONS AND I HAVE PAPERWORK STATING THIS. IT HAS BEEN A FULL YEAR LATER AND THEY HAVEN'T REPAIRED IT YET. THEY CONTINUALLY TELL ME PARTS ARE BEING DESIGNED. JUST WAIT. THAT'S ALL THEY KEEP SAYING. I FOUND OUT THAT THEY MADE A FIX FOR THE V6 MODEL WITHIN 7 MONTHS, BUT THEY DIDN'T HAVE ENOUGH COMPLAINTS AGAINST THE 4 CYLINDER MODEL TO WARRANT REDESIGNING PARTS. I WAS TOLD THIS BY THE SERVICE TECH AT THE DEALERSHIP.
