2005 Toyota Tundra Engine

Suddenly unintended acceleration has happened multiple times with the brake depressed and the accelerator pedal not depressed.

CHECK ENGINE LIGHT SECONDARY AIR INTAKE THIS WAS A RECALL IN 2007-10 YEARS BUT IS ALSO BEEN A COMMON PROBLEM IN EARLIER MODELS. THIS IS A VERY EXPENSIVE REPAIR.

TL* THE CONTACT OWNS A 2005 TOYOTA TUNDRA. WHEN THE ACCELERATOR PEDAL WAS DEPRESSED, THE VEHICLE FAILED TO RESPOND. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE AIR INJECTOR PUMP NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 150,000.

TOYOTA HAS EXTENDED ITS WARRANTY FOR THE AIR INJECTION PUMP AND AIR SWITCHING VALVES ON 2007-2010 TUNDRAS. THE EXTENSION IS FOR 10 YEARS OR 150,000 MILES FROM FIRST USE. I HAVE A 2005 TUNDRA THAT HAS A FAILING AIR INJECTION SYSTEM. I AM WITHIN THE MILEAGE RANGE OF FIRST USE . THE TRUCK HAS THE SAME AIR INJECTION SYSTEM AS THE TUNDRAS WITHIN THE WARRANTY EXTENSION, BUT TOYOTA REFUSES TO HONOR THE WARRANTY EXTENSION ON MY TRUCK. THIS IS A $4000 FIX AND THE TRUCK IS UNSAFE TO DRIVE IN THE CURRENT STATE. *TR

CHECK ENGINE LIGHT CAME ON AND THE TRUCK LOST POWER. THE ENGINE REVVED LIKE IT WAS TRYING TO GO, BUT HAD NO MORE FORWARD MOMENTUM. THE SPEED AT THE TIME OF THE INCIDENT WAS 50MPH. HOOKED UP THE COMPUTER AND THE ERROR CODE READ THAT IT IS THE AIR SWITCHING VALVE. ERROR CODES P-1442, SWITCHING VALVES ARE STUCK CLOSED, #2 IN BANK 1 AND #2 IN BANK 2 OF THE SECONDARY AIR INSPECTION SYSTEM. SAME ISSUE ON 2007-10 TUNDRA AND WAS RECALLED DUE TO DEFECT. MY TRUCK HAS THE SAME ISSUE, HAS UNDER 150,000 MILES, AND HAS BEEN VERY WELL MAINTAINED. TOLD BY TOYOTA THAT IT IS NOT A RECALL AT THIS TIME AND IF THERE IS ONE IN THE FUTURE, THEY WILL REIMBURSE US OUR COSTS. DRIVING DOWN A TWO LANE HIGHWAY WITH 18 WHEELERS BEHIND YOU AND LOSING POWER, GOING 65-70MPH, IS GOING TO CAUSE A WRECK. I DON'T KNOW HOW TOYOTA WOULD REIMBURSE ME MY HUSBAND. *TR

TL* THE CONTACT OWNS A 2005 TOYOTA TUNDRA. IMMEDIATELY AFTER STARTING THE VEHICLE, AIR BEGAN LEAKING FROM THE AIR INJECTION SYSTEM AND THE CHECK ENGINE WARNING INDICATOR ILLUMINATED. THE FAILURE OCCURRED MULTIPLE TIMES. AN INDEPENDENT MECHANIC STATED THAT THE AIR INJECTION SYSTEM NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED AND THE MANUFACTURER WAS NOT NOTIFIED. THE APPROXIMATE FAILURE MILEAGE WAS 126,000.

TL* THE CONTACT OWNS A 2005 TOYOTA TUNDRA. WHILE DRIVING 35 MPH, THE EMISSION CONTROL FAILED AND THE WARNING INDICATOR ILLUMINATED. THE FAILURE OCCURRED TWICE. AN INDEPENDENT MECHANIC RECOMMENDED THAT THE SECOND AIR INJECTION SYSTEM BE REPLACED. THE VEHICLE WAS NOT REPAIRED AND THE MANUFACTURER WAS NOTIFIED. THE APPROXIMATE FAILURE MILEAGE WAS 120,000.

LOSS OF POWER DEALER SAID I NEED A SECONDARY SMOG PUMP AND CHECK VALVES AT A COST OF 2158.90 TRUCK HAS ONLY 38000 MILES FIND OUT IF MY INFO IS CORRECT SAME PROBLEM ON 2007 THRU 2010 AND TOYOTA DID EXTEND THERE WARRANTY. LOSS OF POWER A BIG SAFETY ISSUE. *TR

DASH LIGHT "CHECK ENGINE" CAME ON AND WHEN THE DEALER INFORMED ME THAT IT WAS THIS EMISSION CONTROL SYSTEM LISTED ABOVE ( SECONDARY AIR INJECTION SYSTEM SWITCHING VALVE NO. 2 BANK 1 AND BANK 2) THAT WOULD COST OVER $3,000 I WENT ONLINE AND SAW MANY TUNDRAS AND SEQUOIAS WITH EXACTLY THE SAME PROBLEM AND THAT THE 2007 TO 2009 TUNDRAS WITH THE EXACT PART NUMBERS WERE WARRANTED FOR 10 YEARS, IT TELLS ME THIS IS A KNOWN PROBLEM, SO WHY IS THERE NOT A RECALL? *TR

2005 TOYOTA TUNDRA. CONSUMER WRITES IN REGARDS TO AIR INDUCTION PUMP DESIGN FLAWS *TGW THE CONSUMER STATED ACCORDING TO THE MECHANIC'S REPORT, THE SECOND AIR PUMP, SECONDARY AIR SWITCHING VALVE, BANK 1 AND BANK WERE REPLACED. THEY WERE ALL CLOGGED WITH INSULATION FOAM AND STUCK TO THE VALVE SEATS WHICH KEPT THE VALVES OPEN. THE SECONDARY AIR INLET WAS ALSO REPLACED, DUE TO THE HOSE BEING HARD BECAUSE OF THE HEAT UNDER THE INTAKE MANIFOLD, WHICH ALSO CONTRIBUTED TO THE ENGINE NOT BEING ABLE TO COOL PROPERLY. FURTHER RESEARCH ABOUT AIR INDUCTION PUMP DESIGN FLAWS ON TOYOTA VEHICLE REVEALED A NATIONWIDE PROBLEM AFFECTING TUNDRA'S UP UNTIL THE 2010 MODEL.

AIR INDUCTION PUMP 2005 TOYOTA TUNDRA PUMP FAILURE. DEFECTIVE DESIGN. *TR

MY 2005 TOYOTA TUNDRA HAS A LEAKING EXHAUST MANIFOLD. ON THE WAY HOME FROM THE HARDWARE STORE MY NEW CO DETECTOR WENT OFF INDICATING CO IN THE CABIN. I HAVE CONTACTED THE DEALER AND THE MANUFACTURER AND THEY REFUSE TO REPAIR. *KB

ENGINE LIGHT CAME ON. AFTER HAVING CODES READ, PROBLEM WAS IDENTIFIED AS THE AIR INDUCTION PUMP. THE ISSUE IS THAT WHEN THIS PUMP GOES OUT, IT PUTS THE ENGINE IN A "LIMP" MODE, WHICH CAUSES THE VEHICLE TO NOT HAVE ADEQUATE ACCELERATION TO MERGE WITH TRAFFIC. THIS IS A SAFETY ISSUE AS DRIVERS DO NOT KNOW THAT THE "LIMP" MODE OCCURS WHEN THIS HAPPENS. NEEDLESS TO SAY, THE REPLACEMENT PART COST OVER $1300. I WOULD THINK A PART OF THAT EXPENSE SHOULD LAST LONGER THAN A LITTLE OVER 50,000 MILES.

THE TRUCK WAS BRAND NEW AND ONLY HAD 4,500 MILES ON IT WHEN THE CHECK ENGINE LIGHT CAME ON AND THE TRUCK STARTED ACTING FUNNY. TOYOTA SAID THEY WERE NOT GOING TO FIX IT AND I WAS NEVER GIVEN A REPLACEMENT UNDER LEMON LAW WHEN THIS HAPPENED. I HAD JUST GOT THE TRUCK IN OCTOBER 2005 AND IN DECEMBER 2005 IT STARTED ACTING UP. I AM A TRAINED MECHANIC AND I KNOW THIS SHOULD NOT HAPPEN TO A NEW VEHICLE. I WANT TOYOTA TO REFUND ME THE MONEY I PUT DOWN ON THE TRUCK, WHICH IS AROUND 8 GRAND. *TR

NOTICED LIQUID ON GROUND UNDERNEATH ENGINE AFTER DRIVING. OPENED HOOD TO DISCOVER ANTIFREEZE/COOLANT DRIPPING FROM OVERFLOW RESERVOIR WHICH WAS FULL. COOLANT WAS EXTREMELY DARK BROWN IN COLOR. TOOK IT TO TOYOTA DEALER WHO COMPLETED FLUSH, REPLACED SENSOR, AND FAULTY RADIATOR CAP (TORN GASKET). *TR

DT: WHEN THE ENGINE IS STARTED COLD IT IDLES VERY HIGH. WHEN TAKING FOOT OFF BRAKE OR PUTTING VEHICLE IN GEAR IT ACCELERATES QUICKLY. NO ACCIDENTS REPORTED. ALSO, NO OTHER PROBLEMS. TAKEN TO DEALER TO INQUIRE ABOUT THIS, DEALER STATED THAT THIS IS NORMAL. IT SEEMED TWICE AS FAST AS A NORMAL VEHICLE IN IDLE. WHEN THE ENGINE IS HOT THIS PROBLEM GOES AWAY. *AK *NM
