2011 Toyota Prius 3. ( most models 2010-2014) engineering design flaw allows mice to easily access inside of the vehicle through air system. When mice are present while driving this creates a driving distraction that can lead to an accident or death. Toyota Corp refuses to acknowledge the problem, but the dealership does field complaints but will not act because Toyota refuses to acknowledge the problem an order a bulletin. I have photos and solution to issue, however several others may be unaware of the issue a simple google search will result in additional findings. I myself am a victim of the design flaw and nearly resulted in a car accident. Without being dramatic- this is truly a issue that needs to be reviewed seriously. I cant provide more details if needed. I'm not looking to gain money, media attention or anything else other than there is truly an issue and I want others to be safe. Its heartbreaking to look in the rear view mirror to see a 15 month old baby screaming because a mouse is running across her body and another mouse is running across the back seat and then the floor board under your feet while trying to pull over with no road shoulder.

I was driving on a highway in the country, go about the speed limit of 55 when I heard a very loud sound like an explosion or gunshot. I had the cover to the sunroof open and when I looked up I could see that the sunroof was shattered, crackled everywhere, but intact. When I pulled over to look at it from the outside, I could not see any debris from anything that would have hit it.. instead it appears to bow from underneath and the sides have linear cracks all around. I was not close to another vehicle when it happened either, so I do not see that it could have been caused from anything externally. This could have caused me to be distracted to cause an accident or injury if the glass had entirely fallen through to the inside.

Left car running the night before. Didn't know it. Locked car that evening. Battery dead next day. Shouldn't there have been a warning when I locked car, that car was not off?

On two separate occasions in December of 2013, with two different drivers, the brakes on our 2011 model year Prius (purchased new in February 2012), failed to engage. The first time occurred when I was driving (with one of my teenagers in the car with me), and the second time occurred when my wife was driving the car alone. In both instance we pressed the brake pedal, but the brakes failed to respond at all. Although it is winter, the roads were clear, and the car did not slow down at all when the brakes were pressed / applied. Interestingly, after 30 - 60 seconds, the brake function restored itself. Since December the car has been at the shop at the Toyota dealership where we purchased the car. The shop has been unable to identify the source of the problem. Additionally, the shop indicated they contacted Toyota mechanics and service support staff to help identify and fix the problem, but Toyota claimed they never heard of such a problem or anything like it. Moreover, Toyota refuses to make any repairs or change any parts (even though the car is still under warranty). Yet, this past Wednesday (February 12, 2014), Toyota announced a recall on rav4's and other models for a software problem that causes the anti-brakes to intermittently turn off. This is particularly troubling, given Toyota's claim that they never heard of anything like this and did not know what to fix. Further, Toyota announced a recall on the Prius itself, for a software problem that might cause the car to turn off completely while driving. Clearly, Toyota has a problem with its software in a number of vehicles. At this point, all I have received is corporate double talk, and I urge the NHTSA to pursue this matter as vigorously as possible.

Rear visibility seriously hampered because no camera installed in vehicle. Toyota motor car company knows from experience the serious safety & financial consequences of not addressing a safety issue & a camera providing the driver rear visibility could dramatically save the life of person(child) at rear of vehicle. It is to be noted Toyota installed camera in the Prius only when navigation sys. Is purchased.
