2012 TOYOTA TACOMA Complaints

2012 TACOMA WITH 91,000 MILES: WHILE LEAVING WORK AND TRYING TO ACCELERATE ONTO HIGHWAY THE "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. I TOOK VEHICLE TO MAC HAIK TOYOTA AND RECEIVED THE CODE P2445. I HAD TO REPLACE AIR SWITCH VALVE ASSEMBLY $690, AIR W/BRA PUMP ASSEMBLY $813, AIR TUBE GASKETS $132, LABOR $610. TOTAL $2063!!!! 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 (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 THIS PART NUMBER HAS BEEN SUPERSEDED BY P/N: 25710-31022. *TR

SECONDARY AIR INJECTION SYSTEM TRUCK WOULD NOT ACCELERATE AND LOST POWER. I'VE NOTICED IT HAS DONE THIS SINCE NEW. I NOW HAVE 37,000 MILES ON IT AND HAVE RECEIVED MESSAGES CHECK ENGINE LIGHT AND TRAC OFF MESSAGES. THIS IS VERY DANGEROUS AS YOU HAVE NO ENGINE POWER WHEN ENTERING INTO TRAFFIC. THE TRUCK WILL NOT GO OVER 35 MILES AN HOUR AND TAKES FOR EVER TO GAIN SPEED.

I LEFT THE GYM YESTERDAY AND THE TRUCK HAD NO POWER AND WOULD NOT ACCELERATE, I ALMOST GOT T-BONED PULLING INTO TRAFFIC. I LOOKED DOWN AND THE CHECK ENGINE LIGHT WAS ON AS WELL AS THE TRACTION CONTROL LIGHT. RAN BY AUTOZONE AND HAD THEM SCAN THE OBD AND IT SHOWED P2442 ERROR CODE. I TOOK IT BY THE DEALER THIS MORNING AND THEY SAY BOTH BY-PASS VALVES ARE GONE AS WELL AS THE AIR INJECTION PUMP. ESTIMATE WAS $1,798. THIS IS A 2012 MODEL AS SEEMS TO BE THE NORM WITH THIS FAILURE. BUT WITH ONLY 35K MILES. I TOLD THEM THIS WAS RIDICULOUS FOR THIS TO HAPPEN ON THIS MODEL WITH THIS LOW OF A MILEAGE AND THAT THIS SHOULD BE COVERED UNDER WARRANTY. THE SERVICE REP SAID IT WASN'T AND HER HANDS WERE TIED. I TALKED TO THE SERVICE MANAGER AS WELL AS THE GM. SO FAR TOYOTA HAS REFUSED TO RESOLVE THIS ISSUE IN A FAIR MANNER. THIS IS A KNOW PROBLEM BY TOYOTA ON THE 2012 MODEL TACOMA'S. THEY ARE HAVING THE SAME ISSUE ON THE TUNDRA TRUCKS AND ARE COVERING THESE PARTS UNDER A 150,000 MILE EXTENDED WARRANTY. THERE ARE MANY REPORTS OF THIS SAME FAILURE WITH THE TACOMA'S BUT TOYOTA SO FAR IS REFUSING TO ADDRESS THIS ISSUE. WHEN THIS FAILURE DOES OCCUR THE VEHICLES GO INTO "LIMP" MODE. THIS CAN BE VERY DANGEROUS IF UNEXPECTEDLY YOU LOOSE POWER OR SPEED WHILE MERGING, PULLING INTO TRAFFIC OR ON THE FREEWAY. *TR

SECONDARY AIR INJECTION SYSTEM SWITCHING VALVE ERROR CODE P2440 AND P2442 TRUCK IS NOW IN LIMP MODE AND UNDRIVEABLE

I GOT THE ENGINE LIGHTS ON IN THE MORNING STARTING THE TRUCK ON NOV 3, AND TRUCK WENT INTO LIMP MODE. GOT IT HOME AND LET IT SIT FOR A BIT AND THEN IT SEEMED TO BE OKAY ACCELERATING BUT THE ENGINE LIGHTS WERE STILL ON. TOOK IT TO TOYOTA AND WAS READING THE DREADED P2442 SECONDARY AIR INJECTION SYSTEM CODE. THEY CLEARED THE CODE AND DROVE IT AROUND; CLEARED AGAIN THEY DEEMED IT OKAY AND CHARGED ME $60 FOR THE CODE READ. LEAVE TO DRIVE TO WORK AGAIN THIS MORNING AND BAM, THE LIGHTS BACK ON AND THE THING IS BACK INTO LIMP MODE WITH BARELY ANY POWER TO THE ENGINE. HAD TO DRIVE THIS TRUCK IN THIS UNSAFE CONDITION BACK TO MY HOUSE. I READ SO MUCH ONLINE ABOUT HOW MANY PEOPLE ARE AFFECTED WITH THIS SAME DEFECTIVE PART AND TOYOTA QUOTED ME $2300 CAD + 13% TAX TO FIX IT AND REPLACE THE SECONDARY AIR INJECTION PUMP/VALVE. NOT COVERED UNDER ANY WARRANTY NOR MY EXTRA CARE PROTECTION PLAN I PAID FOR.

AIR INJECTION PUMP AND DIVERTER VALVE ASSEMBLY FAILED CAUSING VEHICLE TO ENTER LIMP MODE. VEHICLE WAS MOVING AT LOW SPEED FROM A FRESH START UP. TOYOTA HAS RECOGNIZED THE ISSUE ON THE TUNDRA TRUCK AND EXTENDED 150K MILE WARRANTY ON THE PART. THEY HAVE NOT EXTENDED THE SAME CONSIDERATION ON THE TACOMA. BASED ON RESEARCH AND DISCUSSION WITH DEALER IT IS A KNOWN ISSUE ON THE 2012 TACOMA. COST TO REPAIR I WAS $1484.14. *TR

HEADED TO WORK TO FIND CHECK ENGINE LIGHT ILLUMINATED. TRUCK HAS LESS THAN 41,000 MILES. WENT TO AUTOZONE, CODE READER PROVIDED P2442 AND P2440 ERRORS RELATED TO THE SECONDARY AIR INJECTION SYSTEM VALVES. FOLLOWED UP WITH LOCAL TOYOTA DEALER. DEALER RAN DIAGNOSTIC AND FOUND SECONDARY AIR INJECTION SYSTEM VALVES STUCK OPEN IN BANKS 1 AND 2. DEALER WANTS TO REPLACE PARTS 17600-0P040: PUMP ASSEMBLY; 25710-31022: VALVE ASSEMBLY; AND THE 4 RELATED GASKETS, PART 17377-31010. QUOTE WAS FOR ALMOST $2400. AGAIN, THE VEHICLE IS 2012, LESS THAN 41K MILES! RESEARCHING THE TACOMA FORUMS ONLINE, THIS APPEARS TO BE A COMMON PROBLEM WITH THIS GENERATION MODEL AND MORE EVEN MORE SO WITH 2012'S. ONE OF THE DEALER'S SERVICE ADVISORS INFORMED ME THAT THIS IS ALSO A COMMON PROBLEM WITH TUNDRAS. FURTHERMORE, WHILE DRIVING, THE VEHICLE WOULD GO IN AND OUT OF "LIMP MODE" AND I HAD NO WARNING AS TO WHEN IT WOULD OR WOULD NOT BE IN THIS MODE, OTHER THAN BY THE WAY THE VEHICLE WAS HANDLING. LIMP MODE WOULD ONLY ALLOW TRANSMISSION TO SHIFT INTO 2ND OR 3RD AND NO MORE THAN 30 MPH, LESS IF CLIMBING AN INCLINE. AT OTHER TIMES, VEHICLE WOULD DRIVE NORMALLY. THE SWITCHING IN AND OUT OF THIS PROTECTIVE MODE SEEMS PARTICULARLY DANGEROUS. *TR

SECONDARY AIR INJECTION VALVE STUCK CODES P2440,P2442. TRUCK GOES INTO LIMP MODE AND YOU CAN ONLY GO A MAX OF 40 MPH.TOYOTA KNOWS ABOUT THESE ISSUES AND DOES NOTHING ABOUT IT

DRIVING ON THE STREET TO WORK ONE MORNING, THE TRAC OFF AND CHECK ENGINE LIGHTS BOTH SUDDENLY APPEARED. I THEN NOTICED THAT MY TRUCK WAS NOT ABLE TO ACCELERATE PAST ~40 MPH. GOING UPHILL, MY TRUCK WAS LIMITED TO ONLY ~20 MPH. MY TRUCK WENT INTO THIS "SAFE MODE." I CONNECTED AN OBD DEVICE AND THE CAME UP WITH THE FOLLOWING TWO CODES: P2440 AND P2442. THE CODES REFER TO "SECONDARY AIR INJECTION SYSTEM SWITCHING VALVE STUCK OPEN" FOR BANKS 1 AND 2, RESPECTIVELY. I DID SOME FURTHER RESEARCH ON THE CODES, AND IT TURNS OUT THIS IS A COMMON ISSUE ON 2012 TACOMAS. APPARENTLY, THE VALVE FOR THE SECONDARY AIR INJECTION SYSTEM IS STUCK OPEN DUE TO MOISTURE AND/OR CARB BUILD UP. I BELIEVE THIS IS A DESIGN/ENGINEERING ISSUE. PART REPLACEMENT COSTS ~$480 FOR EACH VALVE ASSEMBLY. LABOR CAN RANGE ANYWHERE BETWEEN $200-$500. IF THIS IS A KNOWN ISSUE THAT IS COMMON TO A LOT OF 2012 TACOMAS, THEN I BELIEVE TOYOTA SHOULD BE PROACTIVE SUCH AS RELEASING AN OFFICIAL RECALL OR EVEN IMPLEMENT SOME TYPE OF REIMBURSEMENT. NOTE THAT MY TRUCK HAS ~80,000 MILES ON IT. AS AN OWNER, I SHOULDN'T SUFFER FROM AN ENGINEERING DESIGN FLAW AND I SHOULDN'T BE FINANCIALLY RESPONSIBLE TO REPAIR/FIX THE ISSUE. ANY ASSISTANCE WOULD BE HELPFUL. THANK YOU AND HAPPY HOLIDAYS! *TR

MY 2012 TOYOTA TACOMA CHECK ENGINE AND TRACTION CONTROL LIGHT CAME ON. TRUCK WENT IN LIMP MODE, WHICH WAS VERY UNSAFE. TOOK MY TRUCK TO AUTO ZONE TO HAVE THE CODES READ. MY TRUCK CODE WAS P2442. AIR INJECTION SYSTEM SWITCH VALVE STUCK OPEN. THIS IS A KNOWN ISSUE TO TOYOTA TUNDRA TRUCKS BUT NOT FOR THE TACOMA.
