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.

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.

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 CONSUMER STATED ALL HE REMEMBERED WAS EXITING THE HIGHWAY IN EVENING TRAFFIC WHEN ALL OF A SUDDEN, HIS VEHICLE RAMMED INTO THE VEHICLE IN FRONT OF HIM. THE AIR BAGS DEPLOYED PRIOR TO THE COLLISION AND HE HAD NO RECOLLECTION OF BEING ABLE TO BRAKE. HE ALSO STATED THE ENGINE FAILED IN JUNE 2009. THE CONSUMER WAS INFORMED THERE MUST HAVE BEEN SOMETHING WRONG WITH THE SEAMS IN THE RADIATOR. APPARENTLY, IT BLEW OUT THE BOTTOM, WHICH CAUSED THE INSTANTANEOUS LOSS OF THE RADIATOR FLUID. *JB

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
