Selected complaints filed with NHTSA by 2007 Toyota Prius owners, lightly cleaned up (personal details are redacted by NHTSA).
Under hard braking (over 50% of the pedal) the front passenger wheel applies all the force to stop the car to that one tire causing it to lose traction and skid. Brakes are insufficient to properly stop the vehicle and no warning lights are illuminated on the dash. Actually more than half of the time the whole dash does nothing, no MPH, no gas gauge, nothing but a blacked out information less panel. Then to top it off the car only has one headlight bc it blows what ever headlight I put into the ballast. 3 of the most common failures for a 2007 and my Prius has a grand slam assortment of serious potential life threatening problems that should have been repaired (never should have been assembled with) by Toyota. Minor wreck when attempting to stop the car under not driving conditions. …
The contact owns a 2007 Toyota Prius. The contact stated that while driving the speed was unknown due to the instrument cluster being inoperable. On another occasion while driving approximately 45 MPH, the brake pedal was depressed but failed to operate properly; however, on that occasion the instrument cluster was operating as designed. The vehicle stability control, ABS, and brake light warning lights were illuminated. The vehicle was taken to an independent mechanic and diagnosed with an actuator and brake booster failure. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 203,202.
The lights spontaneously turned off while driving on a cloudy night on an unlit section of interstate. While slowing the car down, it went onto gravel, semi-circled around and flipped over onto the lower median. No air bag deployed. No protection from shoulder seat belt. Head hit steering wheel, and I briefly lost consciousness. Tests showed skull and cervical fractures. The car was "totaled." I was planning a move. Now I consider myself to be lucky to be alive. I am rewriting because of previous a NHTSA computer malfunction changing a serious injury to "NO" injury on the questionnaire.
Both headlights failed, one earlier, then the second, on a cloudy night on an unlit, deserted rural stretch of interstate highway. Driver started slowing down from 60 mph, looking for a place to pull over. An accident resulted--only the defective car was involved. No airbag was deployed. The driver was injured. (Full recovery--months.) The car was totaled.
I was driving and all of my dashboard lights disappeared, I couldn't see anything. I was suddenly driving blind. I pulled over but the car would not turn off. I tried again and again, but it would just not turn off. I called Toyota corporate they asked how far I was to a Toyota dealer and told me to take it there immediately. They gave me a case number 220322000191. When I got to the dealer, they said I would have to pay $150 for a diagnosis. I left it there and am now reporting this. There should be a recall on these vehicles, this is extremely dangerous.
I CANT SEE THE ROAD. Who is in charge of allowing these new bright LED headlights? They make it very hard to see where I'm driving when they're eye level with my car!! So all I see is a bunch of LED lights coming straight at me, which is very unacceptable because now I can't see the road. Making it a very obvious safety concern which is weird when I thought the government is supposed to be preventing stuff like this from happening. What the heck
instrument cluster panel goes completely out and blank, speedometer lost, and dash lights gone and causing other issues such as not being able to turn off vehicle, loss of cruise control, unable to open trunk, navigation screen unable to turn off, backup camera not functioning, front lights going on and off while driving at night.
Toyota North America failed to notify me of the latent defect in the Headlight Operating System. I have had ongoing issues with the flickering of the lights for multiple years. I finally saved up enough money to try and fix the problem and spent $2854.34. After multiple failed attempts to get the problem fixed and having both headlights shut off simultaneously, I went to Alexandria Toyota in Virginia on October 20,2022 to get the problem diagnosed. The Automobile Status Report showed that the failed headlights were a direct result of the latent defect in the Headlight Operating System that was repaired free of charge in two separate Support Programs; one that ended in 2012, and the other in 2013. …
My right headlamp has been intermittent for a couple years. It would resolve if I turned headlights on and off, it has become much more of a problem in frequency. I live rural without street lamps and it is becoming more dangerous. I was driving on a country road and hit a deer.
Like so many others have reported, one of the HID headlights will suddenly stop working. Turning the lights off and then on again "fixes" the problem for that moment. But the problem can reoccur within a few minutes. I have experienced this problem most every time I have driven the vehicle at night since the initial incident. Given all the other complaints, and the 2011 class action lawsuit on this issue which Toyota settled without admitting guilt, this is a safety issue well-known to Toyota. Evidence shows the problem is not the light bulbs but the electronic control unit (ECU) or other electrical issue. I have enquired to Toyota customer service. They acknowledge the class action lawsuit and say my vehicle qualifies under the lawsuit, but they will not take responsibility for fixing the problem. …
NHTSA investigations
Headlight failure
Odi opened this investigation after receiving reports that both headlights would go out, or extinguish while driving.the subject vehicles are equipped with high intensity discharge (HID) headlamps that operate on independent lamps and ECU's (electronic control units) for each headlight, meaning that each headlight runs independently of the other, and a failure in one lamp or ECU does not necessarily result in a…
