Six problems related to wiring have been reported for the 2014 Toyota Prius. The most recently reported issues are listed below.
Mice invading inside of car and air conditioning systems. Destroying interior and air filtration system. Can spread disease including hantavirus with droppings. I think this is due to using soy based wire coverings that attrach rodents. Can also affect wiring inside the car.
Seat belt light stayed on, swerve light occasionally. Proved to be rodent damage on wire instruments and blower, panel instrument, antenna assemblies reaching $3,900. Vehicle parked outside residential building on public street in cold rainy weather. Vehicle in excellent condition. Never had such a problem with any other vehicles while living here over 20 years. Could soy based encasing around wiring contribute to this?.
Rodents chewed electrical wiring making the vehicle unsafe to drive. The electronic sensors were rendered inoperable. The vehicle was parked in my garage for the week end. Never had this problem with my other vehicles parked in same garage! repair cost,not covered under warranty was $ 1100. 00.
Rodents chewed through majority of the wiring under the hood and build nests in the engine. This has happened twice and I have only owned the car for 5 months and cost me a lot of money for repairs which Toyota will not cover and said it is not their responsibility for using these soy based wires that attracts rodents.
Driving home (approximately 100 mile journey) - the "check hybrid system" light came on and car warnings indicated needed to stop driving and have car taken to service immediately. Had car taken to dealer for "warranty" service - was told a rodent had eaten the high voltage wiring insulation - not covered by warranty. Have had no evidence of rodent activity at our location, and other vehicles parked here have not had any problems. Being told $2700 repair not covered by warranty that I need to claim on my car comprehensive coverage. Concerned that if it is rodent damage, is it due to materials used that are attractive to rodents (wouldn't this be a problem for all Prius owners), especially in areas that have more of a visible small rodent population? also, don't know how to prove it was manufacturer or design defect - asking dealer to document how they came to believe it is a rodent problem.
