The contact owns a 2012 Toyota Prius. The contact stated that while parked, there were rodents entering the interior of the vehicle. The contact stated that the cabin air filter did not have a mesh grill which was allowing the rodents to enter through a hole in the cabin air filter then into the glove compartment console and into the interior of the vehicle. The dealer was contacted and informed the contact that the wires were soy based causing the attraction of rodents to the hood of the vehicle however the vehicle was not taken for an inspection. An independent mechanic was also contacted who confirmed that the cabin air filter did not have a mesh grill which resulted in the rodents entering through a hole into the cabin air filter then entering into the glove compartment console accessing the interior of the vehicle. The vehicle was then taken to a mechanic where a hardware cloth grill was installed on the cabin air filter. The vehicle was repaired and rodents were no longer entering the vehicle. In addition, the contact was required to clean the feces remaining in the interior of the vehicle utilizing a mask, gloves, and disinfectant and in order to avoid contact with a virus from the feces, the contact was advised not to vacuum let the virus become airborne. The contact was concerned that the rat feces in the vehicle could result in a fatal disease in the event a child would ride in the vehicle and accidentally eat the feces. The contact was concerned that if rodents entered though the air conditioning unit and defecated inside, activating the air condition unit if there was feces, a virus could become airborne. The manufacturer was notified of the failure then informed the contact that the failure was not covered under warranty and that the failure was an outside influence which was not their responsibility. The approximate failure mileage was 40,000. The VIN was not available.

After Toyota power management software recall installed "power management upgrade" software in my car I immediately experienced serious problems with my ignition /start of hybrid/gasoline engine. After pressing ignition, I had to wait 15 to 20 minutes and press start button on/off repeatedly until the gasoline engine ignite but hybrid failed to start. It is not normal because a Prius hybrid engine starts first not the gasoline engine. Toyota has disabled some important functions in its power management recall software update that affects the hybrid engine performance and failure to start. I drive my Prius 3-4 times a month and I did not have any problem before the recall software upgrade because Prius owners manual clearly says that the battery with be disconnected by battery saving function when your car is parked for long time, several days, weeks. In fact, when your car is parked for just days, Toyota power management software (recall) is draining the car battery and reconfiguring the relays to power up the gasoline engine. Toyota owners manual clearly states that when you are parked, "power management software disconnects the auxiliary battery from the hybrid system." However, after the recall, not only auxiliary battery is not disconnected but there are lots of "activity" in hybrid engine that drains the batteries. I called the Toyota service and they now say you have to keep the car on a charger all the time when parked for several days. Of course, it is a huge safety problem to keep the car on a charger all the time when parked for days because the battery is housed in the cabin and the ventilation does not exist unless you park your car outdoors. At the same time Toyota recommends keeping the car on a charger, it also warns of explosion caused by charging the batteries in a garage.

Over the last nine months I have had to replace the bulbs in my 2012 Toyota Prius 6 times. When I brought it to the dealer they stated that it was because I was not using Toyota certified bulb and I paid over $150 to have them inspect the headlights and replace the bulbs. After I had the certified bulbs installed, a bulb went out again. When I returned to the dealer, I was told that I needed new wiring for a cost in excess of $250. The technician stated that tsb-0204-12 was issued for for 2010-11 Prius for this problem and that the 2012 Prius have the exact same wiring harness, but that Toyota was not going to fix that problem for teh 2012 models and that I would have to absorb the cost myself.

I went to start my Prius V. after it was started, a number of the warning lights came on including the ABS and stability control. I was stunned since I had my 30000 mile check up in may with no problems. When I took it to the dealer for repair, the dealer determined that rodents had eaten through a number of the electrical systems because of the soy based wiring. (I understand now that it's "biogradable soy based wiring insulation.) I generally park my car at only two locations - my home and my work. I had never seen any rodents of any type! I can't imagine what would have happened if one of the wires to the engine, or airbags, or any system for that matter separated while I was driving. Apparently, Toyota is aware of this problem but is trying to downplay it! I was told it's not a warranty item. My car requires two new wiring harnesses, the alarm wiring, and the airbag harness plus other repairs.

When our neighbor with a 2013 Prius key fab enters our 2011 Prius it disables the ignition. It will sometimes allow the car to start by touching our key fab to the ignition button however if engine stops, like at a stop light, it will disable the ignition again not allowing you to start the car unless you put your key fab up to the start button again. The dealer knew about the situation and agreed it is a safety hazard but said Toyota will not fix the problem.

Bought car on 1/23/13 and drove home. Next day got a call they forgot to give us access key so drove 27 miles to dealership and smoke on dashboard. Pulled into service and sales manager got in car drove around and said all is fine. Came home an odometer showed 564 miles after I drove 27 there and 27 back. The car had 156 night we bought it the day before. We are old and disabled and do not drive often. Odometer now showing almost 900 miles in less then the 3 weeks we have owned it. Reported the smoke on dashboard to Toyota Corp office and told them how hot the dashboard got and odometer jumping. The man thought it was funny and said he hoped I did not burn my hand. Now nav system not working and radio sounds tinny. Called lakeland Toyota and talked to owner [xxx] who says he is an accountant and knows nothing about cars. Took car to another dealership and was told nav system software 2.1 should be a 2.2 and claimed to have it updated. The car then added another 100 miles again. We need help to make sure car is safe to drive and need miles to stop adding up even when we are not driving. Also the history on mpg one time showed 99.9 and then 26 and then 44.7 and then 49. We had to put gas in it three times in it in less then 3 weeks because gage on dashboard keeps showing getting low but then it only takes 6 gallons. I put no for fire but I did see smoke on the dash above the computer and it was very very hot. So not sure if there was an electrical fire or not or just a surge or short. No one will help me. Need help. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

While driving at night, all lights, especially red in color, which are viewed from front windshield, appear as three distinct images. The source light, then a distinct shadowed light above and below the source. This safety issue is extremely compounded when driving at night in high traffic situations where there are hundrends of tailights in front of me. All those lights are essentially trippled causing confusion and distraction. Toyota refuses to aknowlege the issue. Through research, I have found that this is a common issue with many frustrated owners just living with it because Toyota wont fix it. It is a huge safety issue. Please help make Toyota rectify this huge safety issue before it causes preventable accidents!!

Cigarette/power outlet fuse always blows very frequently - even with a gps use of cellphone charger only. Have been to Toyota dealership and have not addressed the issue after several complaints. Replacing fuses does not address the issue. This is a safety issue for people dependent on gps and communication specially for long travels. ## VIN failed ##

Driving 70 mph car began to go into high RPM, then accelerated to 74 from 70 mph. I tried to decrease speed then vehicle shut off got a long beep and message on display "check hybrid system, pull over immediately" all lights on dash were indicating failures. Coasted to safety with 5 passengers in vehicle across traffic at 9:30 pm to shoulder. Tried to restart several times then vehicle went into high RPM then engine knocked loudly and was completely disabled. Lost brakes, pedal was hard, lost power steering, difficult to maneuver. I still had 2 bars indicating plenty of fuel in car. Prior fillup was 7.6 gallons at pump, usually get over 500 miles per tank, trip meter only showed under 400 miles since fill up so had plenty of fuel and there was no low fuel indicator. Reported all problems to dealer. They only noted the car shut down but told me they confirmed everything I said and that Toyota engineers are trying to resolve this since they are aware of this type of problem. So far dealer and Toyota have not addressed the high RPM, the acceleration, loss of electronics and hybrid system failure and told me they havenever heard of any Toyota ever having a report of a high RPM or acceleration without intent to accelerate form the driver. Vehicle is unsafe, has 4944 miles and this problem occurred about a month after purchase. Toyota still does not know what the problems are and in possession of the vehicle.
