2008 TOYOTA TUNDRA Electrical System Problems

I have multiple problems with the dash lights going on and off , have taken it to car repair when scanned and had replaced relays many times. I have read many stories of people having the same problem with toyota tundras and no one can figure it out. Toyota should have a recall for this because it is not just one or two people with this same exact problem, it is many toyota tundra owners going through the same problems that i' am experiencing.

My truck drove fine then all of a sudden my check engine, vsc and traction control light came on. I brought it to the shop and the code read P 2440. It is in limp mode and the shifting is sporadic.

Since November of 2021 I have my truck towed 20 times due to frame rusting out had it inspected at downeast Toyota in brewer a few years ago to have Frame replacement because all crossmembers where rusted so bed wasn't even on now can mounts completely gone . reason for towing so many tis frame had rusted away pinched wiring harness so I had to pay 1500 for repairs I was always told it was covered.

Vehicle accelerates slow where it takes time for truck to gain spread. Also the cruise control doesn’t work for some reason when button is pushed the cruise light comes on but truck doesn’t cruise on its own.

I WAS DRIVING AND ALL OF A SUDDEN MY TRUCK TURNED OFF A LOT WREAKED MY TRUCK DUE TO LOSING POWER. FUEL PUMP CONTROL MODULE IS BAD. THIS WAS A RECALL IN THE DATA BASE

THE TRUCK WOULD NO LONGER GO PAST 3000 RPM. WRITER DROVE THE TRUCK HOME. IT WAS THEN TAKEN TO TARBOX TOYOTA FOR EVALUATION. THEY NOTIFIED WRITER THAT THE VEHICLE'S SECONDARY AIR INJECTION SYSTEM REQUIRED REPAIR AND THAT THIS IS A KNOWN DEFECT WITH TOYOTA TUNDRAS. TOYOTA ISSUED AN EXTENDED WARRANTY TO COVER VEHICLES IMPACTED BY THIS DEFECT. COST TO REPAIR IS $2300. TOYOTA WILL NOT ASSIST ME WITH THIS ISSUE BUT ADVISED ME TO STOP DRIVING THE VEHICLE. SO THEY ARE AWARE THAT THIS DEFECT IS DANGEROUS YET WILL NOT REPAIR IT UNDER SAID WARRANTY. I CALLED TOYOTA HEADQUARTERS AND THEY WERE OF NO HELP. I AM A NURSE WHO WORKS IN A HOSPITAL DURING THIS PANDEMIC AND I NO LONGER HAVE...

SINCE PURCHASING MY VEHICLE IN NOVEMBER OF 2007, I HAVE NOTICED A "BUG" IN THE ELECTRICAL SYSTEM. IN PARTICULAR, THE RADIO AND AUTOMATIC DOOR LOCKS HAVE GIVEN ME "ISSUES" SINCE THE DAY I PURCHASED MY TRUCK. I'VE NOTIFIED TOYOTA ABOUT THE ISSUE AND THEY HAVE REPLACED THE RADIO AND DOOR LOCK ACTUATORS MULTIPLE TIMES WHEN THE CAR WAS STILL UNDER WARRANTY. AFTER THE TRUCK WAS OUT OF WARRANTY, NO FURTHER WORK HAS BEEN DONE TO THE ELECTRICAL SYSTEM BECAUSE I, PERSONALLY, FEEL THAT TOYOTA SHOULD REPLACE THE ELECTRICAL SYSTEM IN THE VEHICLE INSTEAD OF ATTEMPTING TO HAVE ME PAY FOR THE REPAIRS AS THEY DO THINGS "LITTLE-BY-LITTLE" INSTEAD OF ACTUALLY JUST FIXING THE PROBLEM. I TRULY ENJOY MY VEHICLE AND HAVE NO PLANS TO TRADE, SELL, OR GET RID OF IT, BUT, THE ELECTRICAL SYSTEM HAS ALWAYS BEEN AN ISSUE AND THE FACT THAT SOME OF THE DOORS WILL NOT...

AIRBAG LIGHT GOES ON AND OFF, TOOK IT TO THE TOYOTA DEALER AS THE OWNER MANUAL INDICATES. DIAGNOSE CODE B1801 OPEN SPIRAL CABLE PART# 155740. WHEN THE LIGHT IS ON THE AIR SYSTEM IS DISABLED AND WILL NOT DEPLOY IF IN AN ACCIDENT. WHEN RESEARCHING IF THIS IS COMMON OR NOT, THERE ARE A LOT OF TUNDRA OWNERS WITH THE SAME PROBLEM. THIS SPIRAL CABLE IS EITHER A DEFECTIVE PART TOYOTA USED OR A DESIGN FLAW THEREFORE SHOULD BE RECALLED AND FIXED. TOYOTA DEALER WANTS OVER 750 DOLLARS TO REPLACE THE SPIRAL CABLE. SINCE IT GOES ON AND OFF, TOYOTA OWNERS WILL HAVE TO BE LUCKY IF THEY GET INTO AN ACCIDENT AND HOPE THE LIGHT IS OFF AT THE TIME SO THE AIRBAGS WILL WORK. *TR

TL* THE CONTACT OWNS A 2008 TOYOTA TUNDRA. THE CONTACT STATED THAT WHILE DRIVING AT 50 MPH, THE DRIVERS SIDE AIR BAG AND THE HORN LIGHT ILLUMINATED. IN ADDITION, THE CONTACT STATED THAT THERE WAS AN ABNORMAL NOISE COMING FROM THE STEERING WHEEL WHEN TURING LEFT OR RIGHT. THE STEERING WHEEL WAS DIFFICULT TO MANEUVER.

THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 180,000. UPDATED 09/05/14*LJ THE CONSUMER STATED THE TIRE WARNING LIGHT ILLUMINATED, THE HORN, ABS AND CRUISE CONTROL WERE INOPERATIVE. UPDATED 09/09/14

MY VEHICLE NOW HAS A LITTLE LESS THAN 70,000 MILES ON IT, AND HAS A FEATURE WHICH AUTOMATICALLY LOCKS THE DOORS AT 15 MPH, THEN UNLOCKS THEM WHEN THE TRANSMISSION IS PUT IN PARK. HOWEVER, THE DOORS WILL NO LONGER LOCK UNLESS I DO SO MANUALLY WITH EACH DOOR; THE POWER MECHANISM HAS FAILED. THE DEALER CLAIMS THAT THE CENTRAL RELAY AND CONTROLLER OF THE POWER LOCK SYSTEM IS OK; BUT THE POWER LOCK ACTUATOR (SMALL MOTOR) ON EACH DOOR HAS FAILED INDIVIDUALLY. I FIND IT ALMOST IMPOSSIBLE TO BELIEVE THAT EACH ONE OF THESE PARTS HAS FAILED IN THE SAME VEHICLE RELATIVELY EARLY IN THE LIFE OF THE VEHICLE UNLESS THERE IS EITHER A FAULTY DESIGN OR EXTREMELY POOR QUALITY OF THE PARTS INVOLVED. IN EITHER CASE, THE MANUFACTURER SHOULD BE RESPONSIBLE FOR THE COST OF THE REPAIR, WHICH THE DEALER ESTIMATES AT $1,746.00! PLEASE HELP ME WITH THIS...

THE POWER WINDOWS ON ALL 4 DOORS DO NOT WORK WHEN THE WEATHER GOES TO JUST FREEZING. I DO NOT THINK THERE IS ENOUGH INSULATION IN THE DOORS OR WATER IS ACCUMULATING INSIDE THE MOTORS THAT RUN WINDOWS. I HAVE ONLY OWNED THIS TRUCK SINCE NOVEMBER OF 2012 AND DID NOT DRIVE IT LAST WINTER AS I WORK AWAY FROM HOME FOR MONTHS AT A TIME. THIS WINTER I WAS HOME AND THE POWER WINDOWS DO NOT WORK WHEN IT IS COLD OUTSIDE. I HAVE NEVER EXPERIENCED THIS WITH ANY OTHER VEHICLE IN COLD/FROZEN WEATHER BEFORE SO, I THINK THERE IS SOMETHING WRONG. I LIVE IN WASHINGTON STATE AND IT DOES NOT GET THAT COLD OVERNIGHT HERE WHERE I LIVE JUST DOWN TO FREEZING USUALLY IN WINTER. MY WIFE DRIVES AN ACURA RL 2006 AND HAS NEVER HAD THIS HAPPEN TO HER WITH HER CAR. *TR

REVERSE WARNING SENSORS THAT ALERT YOU THAT YOU ARE CLOSE TO AN OBJECT, SOUND WHEN THEY GET WET EVEN THOUGH NO OBJECT IS NEARBY. THIS CAN BE CAUSED BY RAIN, CAR WASH, OR SIMPLY DRIVING ON WET ROAD AFTER A RAIN. I HAD ONE REPLACED UNDER WARRANTY. NOW ANOTHER IS FAILING AND MY TRUCK IS OUT OF WARRANTY. THIS CAN PRESENT A MAJOR SAFETY ISSUE IN THAT OWNERS WOULD BE USED TO THE SENSORS GOING OFF IN THESE CONDITIONS THAT THEY WILL DISMISS IT WHEN POSSIBLY A REAL OBJECT, HUMAN OR ANIMAL IS PRESENT THUS CAUSING THE "CRYING WOLF" SYNDROME AND POSSIBLE INJURY. *TR

I HAVE A STRONG BELIEF AFTER MY EXPERIENCE THAT TOYOTA HAS A DEFECT WITH "SPEED SENSOR WIRES' AND MAY KNOW AND IS KEEPING IT UNDER WRAPS. MAYBE BECAUSE OF SAFETY PROBLEMS OR THAT IT'S CONTRIBUTING TO A SHORT CIRCUIT AND UNINTENDED ACCELERATION AS PROFESSOR GILBERT HAD DEMONSTRATED ON ABC WITH WHAT COULD HAPPEN WITH A SHORT CIRCUIT IN SOME TOYOTA VEHICLES. SOMEONE FROM TOYOTA HEADQUARTERS THAT WAS VISITING MY DEALERSHIP PERSONALLY INVESTIGATED MY 2008 TUNDRA'S SPEED SENSOR WIRES WHICH ON ONE SIDE HAD COMPLETELY FAILED (SNAPPED COMPLETELY THROUGH) AND WAS FAILING ON THE OTHER SIDE (PARTIALLY BROKEN THROUGH) AT THE SAME SPOT. TOYOTA CHOSE TO REPAIR BOTH BUT RATHER CLASSIFIED THE REPAIRS AS A 'COURTESY REPLACEMENT' VERSUS UNDER THE VEHICLES WARRANTY. THIS I HAVE A STRONG BELIEF WAS DONE TO KEEP IT OFF THE BOOKS BACK AT HEADQUARTERS AND UNDER WRAPS. THIS HAPPENED IN JAN OF 2010. OTHER INDICATIONS THIS...
