2012 TOYOTA TACOMA Complaints

SECONDARY AIR VALVE STICKS CAUSING LOSS OF POWER,,EMISSION SYSTEM WHILE DRIVING AND STAYS ON.

WHILE DRIVING ON A CITY STREET THE CHECK ENGINE LIGHT AND TRAC OFF LIGHT ILLUMINATED AND TRUCK WOULD NOT GO OVER 25 MPH. BROUGHT DIRECTLY TO MECHANIC THAT FOUND DIAGNOSTIC TROUBLE CODE P2442 - SECONDARY AIR INJECTION SYSTEM MALFUNCTION. AT 61K MILES THIS FAULTY PART WAS NOT COVERED UNDER ANY WARRANTY. THE PART COST ALONE WAS $1321 AND THEN ADD TAX AND LABOR FOR A TOTAL OF $1709! SO DISGUSTED WITH TOYOTA FOR NOT TAKING ACCOUNTABILITY FOR THIS FAULTY PRODUCT.

AS I READ THROUGH THE COMPLAINTS ON HERE, IT SEEMS MOST ARE FOR THE SAME ISSUE I HAVE SEEN. AS IT IS THE BIGGEST COMPLAINT ITEM FOR 2012 TACOMA ON THIS WEBSITE, AND THE FACT THAT THERE IS A RECALL ON TUNDRA FOR THE SAME ITEM, AND THAT 2013 TACOMA WERE REDESIGNED TO FIX, THIS IS CLEARLY A KNOWN ISSUE OF A FAULTY PART/DESIGN OF THE THE AIR INJECTION PUMP VALVE. IT IS UNACCEPTABLE THAT NOTHING IS DONE ABOUT THIS AND THE DANGER IT POSES. LIKE THE OTHERS, I GOT A CHECK ENGINE LIGHT/TRAC OFF ONE EVENING WHEN I STARTED MY TRUCK. MY TRUCK STARTED UP FINE, AND I DIDN'T NOTICE A PROBLEM UNTIL I TRIED TO MERGE ONTO A 60 MPH ROAD. I TRIED TO ACCELERATE AND MERGE BUT I ALMOST CAUSED A PILE UP AS I COULD NOT ACCELERATE BEYOND 35 MPH. LUCKILY, ALL I GOT WAS A BUNCH OF HONKING. THIS IS A VERY DANGEROUS SITUATION! AFTER FURTHER RESEARCH, I SAW THE CODES P2440 AND P2442 AND UNDERSTAND IT IS A LIMP MODE DUE TO AN EMMISIONS ITEM AT STARTUP. BEFORE BEING ABLE TO FIX, I HAD TO WORK A SHIFT AT MY SECOND JOB OF SKI PATROL IN THE ROCKY MOUNTAINS. AS MY TRUCK OBVIOUSLY COULDN'T MAKE IT UP THE CANYON, I WAS FORCED TO BORROW ANOTHER CAR, AND ALL I COULD GET WAS A 2 WHEEL DRIVE. THERE WAS A LATE SEASON STORM, AND BECAUSE I DIDN'T HAVE MY 4X4 TRUCK I GOT STUCK OVERNIGHT IN THE MOUNTAINS. I SURVIVED, BUT TWICE BECAUSE OF THIS ISSUE I WAS FACED INTO A DANGEROUS SITUATION. I BOUGHT A NEW 4X4 FOR THE VERY REASON TO AVOID DANGERS LIKE THESE. GRANTED I HAVE 65K MILES NOW, BUT I DON'T EXPECT A VEHICLE TO HAVE MAJOR PROBLEMS LIKE THIS. IT IS EVEN WORSE TO FIND OUT THAT IT IS A KNOWN ISSUE AND NO ONE IS DOING ANYTHING ABOUT IT. IT IS A DISAPPOINTMENT THAT WITH A KNOWN ISSUE TOYOTA HAS NOT DONE SOMETHING ABOUT THIS FOR THE TACOMAS, BUT I AM EQUALLY SURPRISED THAT THERE ARE SO MANY COMPLAINTS AND EXAMPLES OF DANGEROUS SITUATIONS AND THE NHTSA HASN'T DONE ANYTHING EITHER.

ECL CODE P2442, SECONDARY AIR HANDLER, EPA PART BUT TOYOTA DEALERS WON'T COVER UNDER EPA WARRANTY.

AIR VALVES IN EMISSION SYSTEM WENT BAD, WAS REDUCED TO DRIVING 35MPH IN HEAVY TRAFFIC, VERY UNSAFE. WAS QUOTED $2500 IN REPAIRS FOR REPAIRS RESULTING FROM FAULTY DESIGN. REPORTS RAMPANT ON THE INTERNET OF THIS PART FAILING. TPYOTA FIXED THE ISSUE ON LATER MODEL TACOMAS AND RECALLED TUNDRAS WITH THE SAME ISSUE BUT HAVE IGNORED THIS MAKE/MODEL/YEAR.

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 .

ON THE WAY HOME FROM A RECENT CAMPING TRIP MY CHECK ENGINE LIGHT AND TRAC LIGHT CAME ON IN MY TRUCK. THE TRUCK WENT INTO "LIMP" MODE WOULD NOT ACCELERATE UP A HILL ABOVE 20 MILES PER HOUR. WE DROVE TO THE NEAREST AUTO ZONE, THEY PULLED THE CODES P2436 AND P2442. I WAS ABLE TO CLEAR THE CODES AND MAKE IT HOME. I STARTED RESEARCHING THIS AND FOUND THE SECONDARY AIR SWITCHING VALVES TO BE A COMMON FAILURE ON TACOMAS AND TUNDRAS. I FEEL THIS PART NEEDS TO BE RECALLED AND UPGRADED, THIS COULD BE A MAJOR SAFETY ISSUE IF THE VEHICLE WENT INTO "LIMP" MODE IN HEAVY TRAFFIC OR WHILE CROSSING ACROSS HEAVY TRAFFIC. THE REPLACEMENT PART 25710-31022 WAS ORDERED FROM THE DEALERSHIP TODAY. I ALSO FILED A COMPLAINT WITH TOYOTA CUSTOMER SERVICE.

DRIVING HOME FROM WORK ON THE FREEWAY WHEN THE CHECK ENGINE LIGHT CAME ON, THEN THE ENGINE STARTED TO SLOW DOWN AND WOULD NOT GO ABOVE 35 MILES/HOUR ON THE FREEWAY. TOOK TO DEALER AND WAS TOLD SECONDARY AIR INJECTION SWITCHING VALVE STUCK OPEN (BANK 1 & 2) REQUIRING REPLACEMENT.

I HAVE A 2012 TOYOTA TACOMA 4X4 SPORT DOUBLE CAB LONGBED WITH 28860 MILES. I STARTED THE ENGINE AND NOTICED THE "CHECK ENGINE" AND "TRAC CONTROL" LIGHTS ON IN THE CLUSTER. AS I WAS DRIVING I NOTICED A LACK OF POWER IT WAS IN "LIMPED MODE". MADE IT TO MY MECHANIC WHO DID A CODE CHECK WITH READER, CODES P2440 AND P2442 SHOWN WHICH IS SECONDARY INJECTION PUMP VALVE MALFUNCTION. THE CONCERNING ASPECT IS THAT WITH SUCH LOW MILAGE THIS MALFUNCTION OCCURS THAT MAKES THE TRUCK GO INTO LIMP MODE WHICH CAN BE DANGEROUS IN ANY GIVE SITUATION ON THE HIGHWAYS. TOYOTA MUST REALLY CONSIDER INVESTIGATING THIS DEFECT.
