Open the full vehicle complaint log (all categories)TRAC OFF & ENGINE lights came on. Removed gas cap and put it back on. Removed cables to the battery and left them off. Replaced battery cables. Lights remain on. Went to dealership and they charged $100 to scan vehicle. They don't know what's wrong and said it'd be another $800 to check further. They said maybe a rodent had chewed through a cable??? Have seen several reports of this vehicle condition and the battery cable resetting took care of the problem a lot of the time. Not this time. Don't feel comfortable A. driving the truck with these lights on and B. Don't feel comfortable with handing over $800 for them to look into it. What to do?????????????
RODENTS ATE THROUGH THE SOY BASED WIRE INSULATION IN ENGINE COMPARTMENT
MY TRUCK WAS RECENTLY DAMAGED FROM RODENTS,THEY BUILT A NEST BY ENGINE AND CHEWED WIRES. AFTER FURTHER RESEARCH I FOUND THAT AUTO MANUFACTURERS IN ORDER TO GO GREEN ARE USING SOY BASED PRODUCTS ON WIRES INSTEAD OF PETROLEUM. THEY ARE USING SUGAR IN THERE PLASTICS. RICE HUSKS IN THERE INTERIORS. ALL THIS STUFF ATTRACTS RODENTS. THIS IS UNACCEPTABLE! MY DEALERSHIP SAID THEY ARE SEEING AT LEAST 2 RODENT DAMAGED VEHICLES A WEEK. MY TRUCK IS DRIVEN DAILY AND SITS NO LONGER THAN 8 HOURS. THE TOTAL DAMAGE ON A BRAND NEW TRUCK WITH EXTENDED WARRANTY WAS 2700 OUT OF POCKET, THIS DAMAGE WAS NO COVERED BY WARRANTY.
WATER LEAKING INTO PASSENGER COMPARTMENT - SOAKING ELECTRICAL WIRE BUNDLE, SEAT AND FLOOR; DRIPPED AT RIGHT PASSENGER SEAT GRAB HANDLE IN RAIN OR WET SNOW VEHICLE STATIONARY OR MOVING
ELECTRICAL WIRING WAS EATEN BY SOME KIND OF RODENT - TWICE! DASH PANEL LIGHTS CAME ON, SO I TOOK IT TO THE DEALER SINCE IT WAS NEW. DEALER REPORTED THAT THE ELECTRICAL WIRING HAD BEEN EATEN BY SOME KIND OF RODENT. THE REPAIR WAS MAKE ($500.53 DISCOUNTED), AND THE FIRST NIGHT THE TRUCK WAS BACK IN FRONT OF THE HOUSE - IT HAPPENED AGAIN. WE LIVE IN THE CITY WITH MANY VEHICLES PARTED IN THE STREET. I HAVE LIVED IN THE SAME HOUSE FOR OVER 27 YEARS AND HAVE ALWAYS HAD A VEHICLE PARKED IN MY DRIVE WAY WITH NO RODENT PROBLEM. WHY NOW? WHY THIS VEHICLE? ACCORDING TO A DEALER SERVICE PERSON (AND COLLABORATED ON-LINE), CAR MANUFACTURERS (TOYOTA INCLUDED) ARE TRYING TO BECOME MORE "GREEN" AND HAVE BEGUN USING MORE PEANUT AND SOY PRODUCTS IN THE MANUFACTURING OF ITS WIRE INSULATION AND RUBBER HOSES - THUS ATTRACTING ANIMALS. ALSO, THE DESIGN OF THIS V6 ENGINE HAS A SPACE JUST UNDER THE ENGINE COVER THAT SMALL ANIMALS FINE INVITING AND WARM. THE ANIMAL GO INTO THIS SPACE AND NAUGHT ON THE WIRES THAT ARE PRESENT. MY LOCAL DEALER COVERED THE SECOND REPAIR, AND WAS GREAT TO WORK WITH. HOWEVER, THERE SEEMS TO BE A DESIGN/MANUFACTURING ISSUE THAT IS OUT OF THE CONTROL OF THE DEALER. MY SOLUTION = FILL THE SPACE WITH CHICKEN WIRE. SO FAR. SO GOOD. *TR
