2011 Toyota Tundra Electrical System

HORN DOES NOT OPERATE THE ONLY TIME IT WORKS IS WHEN TURNING THE STEERING WHEEL. *TR

2011 TOYOTA TUNDRA CHECK ENGINE LIGHT, 2LO, AND TRACTION CONTROL LIGHT ALL CAME ON. TOOK TO DEALER, DEALER FOUND RODENT DAMAGE TO WIRING HARNESS. REPLACED WIRING HARNESS AND CLEANED OUT MOUSE NEST. RODENTS WERE ATTRACTED TO SOY BASED WIRING USED IN TUNDRA TRUCKS. OVER $600 IN DAMAGE, NOT COVERED BY TOYOTA, BUT SHOULD BE!

SEVERE DAMAGE HAS BEEN DONE TO THE ELECTRICAL WIRING FROM RODENTS CHEWING THE WIRING.

MOST DOOR LOCKS DO NOT LOCK/UNLOCK AUTOMATICALLY. IT'S GETTING WORSE. I FEAR I WILL BE LOCKED IN OR OUT VERY SOON IF NOT FIXED. IF I HAD TO GET IN THE TRUCK QUICKLY FOR SAFETY, I COULDN'T. USUALLY 2 OF THE 4 WILL NOT WORK - BUT YOU NEVER KNOW WHICH ONES. HAVE TO MANUALLY UNLOCK/LOCK OTHER DOORS FROM INSIDE.

MY 2011 TOYOTA TUNDRA HAS EXPERIENCED ISSUES WITH THE INTERNAL CLIMATE CONTROL SYSTEM FROM DAY 1 OF PURCHASE. I HAVE DISCUSSED THIS WITH TOYOTA AND HAVE HAD IN FOR SERVICE AT LEAST 5 TIMES. THE RECIRCULATION BUTTON (WHICH IS ELECTRONIC, NOT MANUAL) WILL AUTOMATICALLY SWITCH OFF WHILE DRIVING EVERY THREE (3) MINUTES AND ALLOW OUTSIDE AIR TO FLOW IN. WHILE QUITE ANNOYING AT TIMES, IT IS ESPECIALLY DANGEROUS WHEN I VISIT MY CABIN IN JULIAN CALIFORNIA IN THE WINTER, AND THE SWITCH TO OUTSIDE AIR BLOWS IN THE OUTSIDE 20 DEGREE F WEATHER, WHILE DRIVING 20 MILES DOWN A VERY DARK (NO LIGHTING) AND VERY CURVING ROAD POPULATED BY MANY DEER. MY ATTENTION IS FOCUSED ON THE CENTER CLIMATE CENTER, AND NOT THE ROAD AHEAD. TOYOTA HAS GIVEN ME MANY EXPLANATIONS, SEVERAL WHICH WERE INCORRECT, AND NOW THEY JUST CONCEDE THAT IT'S WORKING EXACTLY AS DESIGNED. THEIR REHEARSED ANSWER IS THAT ALL CARS SHOULD ONLY BE DRIVEN WITH THE OUTSIDE AIR COMING IN TO AVOID RECIRCULATED MOISTURE DAMAGE TO THE INTERIOR. THIS DOES NOT WORK IN FREEZING WEATHER! I'VE BEEN ON THE WEB TO THE TUNDRA FORUM, AND OTHERS VOICE THE SAME COMPLAINT. AN AIR RECIRCULATION CONTROL WHICH WILL NOT STAY ENGAGED AND ALLOWS IN EXTREME COLD WEATHER, DIESEL FUMES, ETC. IS A SAFETY ISSUE. TOYOTA HAS SHOWN ME THE OPTIONS WITHIN THE COMPUTER, AND THERE ARE APPARENTLY NO OPTIONS TO OVERRIDE THIS ISSUE. ANY HELP OR ASSISTANCE WOULD BE GREATLY APPRECIATED.

I WAS HEADED TO SPRINGFIELD ON I-95 AND A CAR WAS COMING INTO MY LANE AND I TRIED TO BLOW THE HORN AND THERE WAS NOTHING. I ENDED UP SWERVING INTO THE LEFT LANE WITH TRAFFIC COMING. IT'S HAPPEN A FEW TIMES. I CHECKED MY FUSE AND IT WAS FINE. I ENDED UP HAVING TO REPLACE THE AIR BAG CLOCK SPRING. IT WAS A CLOSE CALL FOR A PILE UP SITUATION LET ME TELL YOU. $365.33 TO HAVE THE AIR BAG CLOCK SPRING REPLACED. THAT SHOULD OF NEVER HAPPEN.

THE TUNDRA IS KEPT IN OUR GARAGE AND IS DRIVEN ONE OR TWO TIMES A WEEK. ON CHRISTMAS DAY 2014, WHEN I DROVE THE TUNDRA, I NOTICED A NUMBER OF UNUSUAL LIGHTS FLASHING ON THE DASH, INCLUDING THE CHECK ENGINE LIGHT. WHEN I EXAMINED THE ENGINE, I FOUND A RATS NEST ON TOP, AND I SUSPECTED A RODENT HAD DAMAGED THE WIRES. I TOOK THE TUNDRA TO THE LOCAL TOYOTA DEALER, AND THE SERVICE REPRESENTATIVE TOLD ME THAT THE INSULATION ON THE WIRES OF MY TUNDRA CONTAINS SOY WHICH IS ATTRACTIVE TO RODENTS. IT TURNS OUT THAT 7 WIRES NEEDED TO BE OVERLAID AT A COST OF $760. IT SEEMS TO ME THAT PUTTING SOY IN THE INSULATION AROUND ELECTRICAL WIRES IS A DESIGN FLAW THAT COULD LEAD TO RODENT-CAUSED DAMAGE THAT COULD LEAD TO SAFETY PROBLEMS. I DID SOME GOOGLE RESEARCH, AND IT APPEARS THAT THIS FLAW HAS BEEN KNOWN SINCE AT LEAST 2011, AND WAS DESCRIBED IN AN ARTICLE IN MOTOR AGE MAGAZINE. I DO NOT KNOW IF RODENT-DAMAGED WIRES HAVE CAUSE ANY AUTOMOBILE ACCIDENTS, BUT THEY ARE CAUSING AMERICAN CONSUMERS A GREAT DEAL OF MONEY. FOR EXAMPLE, I READ THE TESTIMONY OF A 2012 TOYOTA HIGHLANDER OWNER WHO HAD RODENT-CAUSED DAMAGE THAT REQUIRED $6,400 IN REPAIRS.
