NHTSA Complaint #10332041 — 2007 TOYOTA TUNDRA

AIR INJECTION SYSTEM FAILURE CAUSES A CHECK ENGINE LIGHT TO APPEAR AND CAN CAUSE THE VEHICLE TO GO INTO "CRIPPLE" MODE LIMITING THROTTLE AND SPEED TO 40 MPH WHICH COULD BE A SERIOUS SAFETY CONCERN IN SOME DRIVING CONDITIONS. DEALER STATED THEY ARE "FIXING" ~2 VEHICLES A DAY AND REPLACING THE AIR INJECTION PUMPS AND VALVES FOR A TOTAL COST OF ~$4000 IF THE VEHICLE IS NOT UNDER WARRANTY ANYMORE. IN MY CASE, THE DEALER REPLACED ONE PUMP A WEEK AGO AND NOW THE SECOND PUMP HAS FAILED ($1100 FOR EACH PUMP). THERE HAS NOT A DESIGN CHANGE TO THE PUMPS OR VALVES IN THE SYSTEM WITH THE REPLACEMENT PARTS SO THE FAILURE WILL HAPPEN AGAIN IN ANOTHER 30-50K MILES. DEALER CLAIMS MOISTURE IN THE SYSTEM IS CAUSING THE PROBLEMS. A QUICK GOOGLE SEARCH ON THE PROBLEM SHOWS THE PROBLEM IS SYSTEMIC WITH 2007+ TUNDRAS AND SEQUOIAS WITH THE 5.7L V8. OTHER MANUFACTURES USE AN AIR INJECTION SYSTEM WITH A MUCH LOWER COST AND THERE DOES NOT SEAM TO BE ANY PROBLEMS WITH THEM. *TR
