2012 Toyota Tacoma Other Problems

Your truck suddenly lost power while driving at 60 mph, forcing you into a ditch to stop. After the mechanic replaced the rack and pinion steering component, the check engine light came on. Multiple mechanics have refused to continue repairs due to extensive rust and corrosion throughout the vehicle, citing liability concerns that rust damage could spread to other components during repair work. Addressing this issue will require both identifying why the engine lost power (likely through diagnostic codes) and managing the underlying rust corrosion that's preventing repair shops from safely working on the vehicle.

Your truck's accelerator suddenly engaged on its own while you were trying to park, causing the vehicle to accelerate uncontrollably. The truck crossed multiple curbs, a road, and a fence before going down a retaining wall into a wooded area. This is the second time your truck has experienced unexpected acceleration—the first incident was reported to Toyota in August 2019, but Toyota's investigation of the black box data found no evidence of a mechanical problem.

Your truck's frame has developed rust that has eaten completely through the metal in multiple locations. This is a structural integrity issue that will require professional inspection and repair. Fixing this typically involves cutting out the rusted sections and welding in new steel reinforcement panels.

21012 TACOMA WITH 52,000 MILES IN NEED OF REPLACEMENT AIR SWITCHING VALVES, AIR PUMP & GASKETS. KNOWN PROBLEM WITH TOYOTA OF WHICH THEY ONLY MADE A HANDFUL OF RECALLS TO OWNERS. $1500 FOR REPAIRS THAT SHOULD BE COVERED BY TOYOTA

THE CODES FOR THE AIR SWITCHING VALVE.

THE HORN DOESN'T WORK. THE PROBLEM HAS BEEN DIAGNOSED AS "CLOCK SPRING" AND THE COST TO FIX IT IS ALMOST $500. THIS IS A LOT TO PAY FOR SOMETHING THAT SHOULD NEVER GO OUT! RELAY AND FUSE CHECKED OUT.

AT LESS THEN 50K MILES ON THE ODOMETER AND 900 MILES FROM HOME MY TRUCK DECIDED TO GET A CHECK ENGINE LIGHT AND TRAC OFF LIGHT CAUSED BY CODES P2440 AND P2442 AND P2445. MERRY CHRISTMAS TO ME. THESE CODES PUT ME INTO LIMP MODE WHILE ON THE FREEWAY IN SNOWY AND ICY CONDITIONS. I COULD NOT MAINTAIN SPEED WITH THE FLOW OF TRAFFIC AS I WAS TRYING TO GET TO THE SHOULDER WITH TRAFFIC ZOOMING ALL AROUND ME, DANGEROUS AND SCARY! TOYOTA WANTS $2000 TO REPAIR IT. INTERNET RESEARCH HAS SHOWN ME THAT IT IS A COMMON PROBLEM THAT TOYOTA FAILS TO RECOGNIZE FOR TACOMAS BUT HAS ISSUED A TSB AND EXTENDED WARRANTIES FOR TUNDRAS. SHAME ON TOYOTA. NOW I GET TO ENDURE THE COST OF REPAIR AFTER THE HOLIDAY SEASONS AND I'M SURE MY BOSS WILL LOVE TO HEAR I WONT BE RETURNING TO WORK ON TIME.

SECONDARY AIR CONTROL VALVE FAILURE IN THE OPEN POSITION

SECONDARY AIR INJECTION SYSTEM FAILURE CAUSED MY VEHICLE TO ENTER LIMP MODE IN A HIGH SPEED/HIGH TRAFFIC AREA. "LIMP MODE" RENDERS THE VEHICLE INCAPABLE OF SPEEDS HIGHER THAN 30 MPH. CAUSING A HAZARD TO OTHER MOTORISTS, I EXITED THE HIGHWAY AS QUICKLY AS POSSIBLE. UPON RESEARCHING THE TOPIC I CAN PLAINLY SEE THIS IS SOMETHING THAT IS QUITE COMMON WITH MY PARTICULAR VEHICLE. HOWEVER, OTHER MODELS MADE BY THE SAME MANUFACTURER ARE BEING RECALLED AND REPAIRED WHILE THE MODEL I OWN IS NOT. IN ADDITION TO MODEL, THE YEAR OF MY VEHICLE SEEMS TO BE EXPERIENCING AN UNUSUALLY HIGH VOLUME OF FAILURES. FILING A COMPLAINT HERE IS ONLY APPROPRIATE AND APPROPRIATELY, THE AUTOMOTIVE MAKER SHOULD BE HELD RESPONSIBLE.

I WAS PULLING OUT ON TO THE HIGHWAY AND MY TRUCK FAILED TO EXCEED 30 MPH WITH ONCOMING TRAFFIC WHICH NEARLY CAUSED AN ACCIDENT. UPON INSPECTION BY MY TOYOTA DEALERSHIP, THEY EXPLAINED THAT MY SECONDARY AIR INJECTION VALVES WERE STUCK OPEN (P2440, P2442) WHICH CAUSED THE TRUCK TO LOSE ALL POWER. I WAS THEN TOLD THAT SINCE I AM NO LONGER UNDER WARRANTY (MY TRUCK IS ONLY 5 YEARS OLD WITH 48,000 MILES ON IT) THAT TOYOTA WOULD NOT COVER THE 2,000 DOLLAR COST TO HAVE THE PART REPLACED. UPON FURTHER RESEARCH, COUNTLESS OTHERS WERE HAVING THE SAME ISSUE. THE TOYOTA TUNDRA ALSO HAD THIS ISSUE AND AN EXTENDED WARRANTY WAS OFFERED FOR THOSE VEHICLES. SINCE TOYOTA KNOWS THIS IS AN ISSUE IT IS MY BELIEF THAT THEY SHOULD STAND BY THEIR PRODUCT AND FIX THE DEFECTIVE PART WHICH IS A HUGE SAFETY ISSUE AS I FOUND OUT. FURTHERMORE, THERE IS NO REASON THIS EMISSIONS PART SHOULD EVER SHUT DOWN THE POWER TO THE TRUCK WHILE DRIVING. THANK YOU FOR YOUR TIME.

P2442

P2442 TOYOTA SECONDARY AIR INJECTION SYSTEM SWITCHING VALVE STUCK OPEN BANK 2 I HAVE GOT THIS CODE THREE TIMES NOW AND THE SECONDARY AIR INJECTION PUMP AND VALVES WILL HAVE TO BE REPLACED. THERE IS 33,282 MILES ON THE TRUCK RIGHT NOW. MANY, MANY, MANY COMPLAINTS ONLINE ABOUT THIS ISSUE BUT TOYOTA IS IGNORING IT. $1900 FIX IS VERY STEEP FOR A TRUCK WITH 33K MILES.

VEHICLE WAS IN MOTION ON RAINY, WET HIGHWAY WHEN CHECK ENGINE LIGHT WENT ON AND TRACTION CONTROL WAS SHUT OFF. THE SECONDARY AIR INJECTION SWITCHING VALVE IS APPARENTLY STUCK CLOSED, WHICH FOR SOME REASON SHUTS OFF THE TRACTION CONTROL. IT IS MY UNDERSTANDING FROM SPEAKING WITH OTHER TACOMA AND TUNDRA OWNERS THAT HAD THE VALVES GOTTEN STUCK OPEN, THE VEHICLE GOES INTO "LIMP MODE" WHICH AUTOMATICALLY DECREASES SPEED TO 20MPH. OBVIOUSLY, EITHER OF THESE OCCURRENCES ARE PARTICULARLY UNSAFE IN RAINY AND WET CONDITIONS, AND THE DECREASE IN SPEED IS UNSAFE DURING ANY HIGHWAY TRAVELING. THIS IS APPARENTLY A BIG ENOUGH ISSUE ON THE TUNDRA MODELS FOR TOYOTA TO EXTEND THE WARRANTY TO 150,000MI, YET THEY HAVE DONE NOTHING FOR THE TACOMAS WHICH HAVE AN IDENTICAL SYSTEM AND PARTS.

SECONDARY AIR INJECTION PUMP. RECEIVING P2442 CODE AND TRUCK IS GOING IN TO LIMP MODE

ERROR 2440/2442 CAME UP A FEW DAYS AGO WHEN STARTING THE TRUCK TO GO TO WORK(COOL MORNING) - SECONDARY AIR INJECTION SYSTEM SWITCHING VALVE STUCK OPEN BANK 1/2. I FIRST NOTICED THAT IT INDEED PUT THE TRUCK INTO LIMP MODE, WHICH CAUSES THE ENGINE TO DECREASE POWER SO I COULD HARDLY ACCELERATE.(PRESSURE SENSOR IN EXHAUST WENT OFF BECAUSE VALVES WERE STUCK OPEN) I KNEW EXACTLY WHAT THE PROBLEM WAS DUE TO MANY HAVING THE SAME ISSUES ON A TACOMA FORUM I AM ON.(ALL WITH EARLY 2012'S, A REDESIGNED PUMP WAS MADE AND INSTALLED ON LATER BUILT 2012S) I TOOK APART THE SYSTEM AFTER GETTING A SHAFT FROM MY LOCAL DEALER SAYING IT WAS UNDER POWERTRAIN WARRANTY.(KNEW IT WAS UNLIKELY AS I HAVE ALMOST 70K MILES, BUT THOUGHT WHY NOT TRY) AFTER READING ABOUT OTHER'S WAYS OF SOLVING THE ISSUE, I TOOK APART BOTH THE AIR PUMP AND VALVE ASSEMBLY TO INSPECT THEM. I WAS AMAZED TO FIND A SOAKED AIR FILTER WITH WATER SITTING IN THE PLASTIC MOLDING UNDER IT, I ALSO FOUND THE RUBBER HAD BEEN BURNT UP IN THE VALVE ASSEMBLY, ALONG WITH DEPOSITS DUE TO MOISTURE.(PICTURES ATTACHED) FROM WHAT I HAVE READ, AND WHAT I HAVE SEEN, TOYOTA INSTALLED THIS DEFECTIVE SYSTEM ON EARLY 2012 TACOMA'S BEFORE A REDESIGNED PUMP(NOT SURE ON VALVES) AND PROGRAMMING THAT IS SUPPOSED TO RUN THE AIR PUMP AFTER THE ENGINE SHUTS OFF TO GET RID OF THE MOISTURE. I BOUGHT NEW VALVES FOR $479, BUT WILL ALSO HAVE TO BUY A BYPASS FOR $350 BECAUSE I KNOW THE AIR PUMP WILL STILL BRING IN MOISTURE AND CAUSE THE VALVES TO FAIL AGAIN, THIS BYPASS ALLOWS THE PUMP/VALVES TO COMMUNIATE TO ECU THAT THEY RUN OK BUT THE AIR PUMP NEVER RUNS. TOYOTA ISSUED A TSB FOR TUNDRA'S AND SEQUIOA'S FOR THE SAME REASON, YET THEY ARE IGNORING TACOMAS.(ATTACHED PDF) ALSO JUST NOTICED ON THIS TSB THEY WERE VERY QUICK ABOUT ISSUING IT AS WELL, CAN'T SEE HOW THEY DIDN'T KNOW THAT TACOMA'S HAD THE SAME SYSTEM INSTALLED.

P2440-P2442 ERROR CODE. SECONDARY AIR INJECTION VALVES AND PUMP. A POORLY ENGINEERED PART THAT CONTINUES TO BREAK AND TOYOTA WONT ADDRESS THE ISSUE LIKE IT HAS ON THE TUNDRA & SEQUANA (SP). THEY KNOW THEY HAVE A BAD PART .

I WAS DRIVING TO WORK THIS MORNING AND WHEN ENTERING A HIGHWAY MY TRUCK COMPLETELY STOPPED ACCELERATING AND WOULD NOT GO OVER 40 MPH, ANF WOULD NOT GO OVER 1200 RPMS. I HAVE RESEARCHED THE CODES THAT POPPED UP FROM MY CHECK ENGINE LIGHT, AND HAVE FOUND A TON OF OTHER PEOPLE ARE HAVING THE SAME ISSUE. THE CODE IS P2442, AND INDICATES A FAILED AIR INJECTOR THAT THE MANUFACTURER HAS NOT ISSUED A RECALL OR SAFETY ADVISORY.

CHECK ENGINE LIGHT AND TRAC OFF APPEARED AND TRUCK ENTERED LIMP MODE. CODES P2440/P2442 ON DIAGNOSTICS. SECONDARY AIR INVERTER FAILED ALONG WITH AIR PUMP. EMISSIONS CONTROL PROBLEMS. TOYOTA DID NOT ACKNOWLEDGE ANY RESPONSIBILITY.

A PROBLEM COMMON TO TOYOTA'S OCCURRED WITH MY VEHICLE. THE SECONDARY AIR INJECTION PUMP FAILED. THE TACOMA DID NOT HAVE SUFFICIENT POWER AND WOULD NOT REACH CERTAIN RPM'S. THE BILL IS $2,500. THE DEALERSHIP TOLD ME IT HAPPENS QUITE OFTEN WITH TOYOTAS. THEY HAVE SAID THIS IS NOT PART OF THE POWERTRAIN WARRANTY.

AT 57000 MILES CHECK ENGINE AND GETTING P2442 CODE AT START-UP. CHECKED AND IT IS A BAD SECONDARY INJECTION PUMP. CHECKED ON INTERNET AND THERE ARE MANY OTHERS WITH THE SAME PROBLEM AND TOYOTA SAYS IT'S NOT UNDER WARRANTY $1900 TO FIX

THE ENGINE LIGHT CAME ON - TOOK TO DEALER - WAS TOLD SECONDARY AIR FLOW AND PUMP NEED TO BE REPLACED.

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 FAILURE AT 58K MILES. DEALER QUOTED $2200 TO REPLACE VALVES AND PUMP. SEVERAL FAILURES WITH 2012 REPORTED

THE SECONDARY AIR INJECTION PUMP'S VALVES WENT BAD WITH THE VEHICLE ONLY HAVING 30K MILES. THIS CAUSED THE TRUCK TO GO INTO LIMP MODE AND DID NOT ALLOW FOR ACCELERATION WHILE DRIVING. THIS IS A VERY DANGEROUS ASPECT WHEN DRIVING ON THE FREEWAY. NOTHING HAPPENED TO THE VEHICLE TO CAUSE THIS FAILURE, IT JUST STARTED UP ONE DAY AND WAS BAD.

TAKATA RECALL I STOPPED THE AT TRAFFIC LIGHT ION CITY STREET WITHOUT RAIN. I JUST STARTED DRIVING, WHEN LIGHT CHANGED TO GREEN, THERE WAS NO STEERING FEELING AT ALL FOR A FEW SECOND. THE CAR WAVED SIDE BY SIDE TWICE WITHOUT MY CONTROLLING. THEN I DROVE SLOWLY AND CAREFULLY, IT'S OK. I BOUGHT CAR TO TOYOTA DEALER THE NEXT DAY, THEY SAID STEERING SYSTEM IS OK, MAY BE BECAUSE OF WET BELT.

THERE IS A PLASTIC FOOT REST ON THE DRIVER'S SIDE FLOOR BOARD THAT COMES LOOSE AND GETS TANGLED UP IN THE DRIVER'S FEET WHILE DRIVING. THIS CREATES A DRIVING HAZARD AND COULD CAUSE AN ACCIDENT.

SECONDARY PUMP DOES NOT WORK WHEN IS COLD TURNING TRAC AND ING LIGHT ON CAUSING LOOSE OF POWER AND HIGHT GAS CONSUMING. DEALER SAYS WARRANTY DOES NOT COVER.

THE SECONDARY AIR INTAKE PUMP AND SWITCHING VALVE STOPPED WORKING AFTER ONLY 28,000 MILES. CAR WENT DIRECTLY IN LIMP MODE MAKING IT UNDRIVABLE. DEALER WANTED $2,100.00 FOR PARTS AND LABOR AND SAID IT WAS NOT COVERED UNDER THE WARRANTY.

AFTER STARTING TACOMA, CHECK ENGINE LIGHT AND "TRAC OFF" LIGHT CAME ON, WENT INTO LIMP MODE, COULD ONLY GO 30MPH. TACOMA JUST HIT 34,000 MILES. DEALERSHIP STATED SECONDARY AIR INJECTION VALVE STUCK CLOSED BANK 1 (CODE P2441). WAS TOLD PUMP AND VALVES NEEDED TO BE REPLACED AT $2100, INCLUDING LABOR. CALLED TOYOTA CORPORATE, TOLD IT WAS NOT COVERED UNDER POWER TRAIN OR EMISSIONS WARRANTY. THIS ISSUE ACTUALLY FIRST OCCURRED APPROXIMATELY 4 MONTHS AGO WHILE DRIVING ON A CITY STREET. WARNING LIGHT CAME ON AND WENT INTO LIMP MODE. PULLED INTO A FIRESTONE AND THEY SAID IT WAS ALSO CODE P2441. THEY RESET IT AND IT DIDN'T HAPPEN AGAIN UNTIL A FEW DAYS AGO. THIS TIME THE CODE WOULD NOT RESET, WARNING LIGHT WON'T TURN OFF AND REMAINS IN LIMP MODE.

SECONDARY AIR INJECTION VALVE FAILURE AT 53K MILES, TOYOTA WOULD NOT COVER UNDER MY POWER TRAIN OR EMISSION WARRANTY. TRUCK WAS PUT INTO LIMP MODE WHEN THE FAILURE HAPPENNED AND WAS UNDRIVABLE.

CHECK ENGINE LIGHT CAME ON AND VEHICLE WAS NOT GOING PAST 2K RPM AND OVER 20MPH. CONNECTED TO AN ONBOARD DIAGNOSTIC READER WHICH GAVE ME CODES P2440 AND P2442- SECONDARY AIR INJECTION VALVE STUCK OPEN BANK 1 & 2. VEHICLE HAS LESS THAN 50,000 MILES AND ONLY 4 YEARS OLD AND TOYOTA DOES NOT COVER FAULTY EQUIPMENT UNDER ANY WARRANTY (POWERTRAIN OR FEDERAL EMISSIONS) ALTHOUGH THEY HAVE ISSUED CANADA TSB 3861 ACKNOWLEDGING THE DEFICIENCY, BUT LEAVING THE OWNER TO PAY $645.00 FOR THE REPLACEMENT PART FROM TOYOTA DEALER. THIS IS UNSATISFACTORY- THEY MUST BE HELD ACCOUNTABLE FOR A VEHICLE STILL WITHIN POWERTRAIN (60,000MI) OR FEDERAL EMISSION (80,000MI) WARRANTY.
