I was driving my 2009 Toyota Prius on a very cold day (roughly 10 to 20 degrees f). The red brake warning light was on, along with the abs, vcs and yellow "!" lights. The brakes were extremely soft for about the first 5-10 minutes of operation. I would push the brake pedal as far as it would go (it would not go all the way to the floor) and the brakes would seems to be engaging at about 30%-50% of their normal stopping power. After the vehicle warmed up, the warning lights on the dash went away and the brakes began operating normally. The following week, my wife was driving the vehicle on another very cold day (again probably about 10 degrees). She stated that the above mentioned lights stayed on for her entire commute (less than 10 minutes) but that when she arrived to work, her brakes were not working. She described that she pressed the brake pedal as far as it would go, but the brakes did not seem to be fully engaging. She stated that she nearly hit a wall as she was pulling into the parking lot at her work. I have found similar issues listed on Prius forums online. Perhaps it is a electrical or computer problem as opposed to a problem with the brakes. We have never had the problem when the temperature was above 25 degrees.
We were driving on the highway at about 70 miles per hour when the reading lights and dashboard flashed on and then off in a matter of about 5 seconds. The dash showed a triangle indicator light with an exclamation point. The dash also seemed to reset and showed the display as is the car had just been turned on. This incident happened twice within a 4 hour period. Once on the highway and once on a back road going about 40 mph. The car did not stop either time, but it is still concerning.

The headlights go dim and /or shut off as I am driving. This problem usually starts with the right headlight shutting off and sometimes both will go dim or shut off completely. Both lights work initially on startup and shine bright at first but immediately dim to a lower level and then as I drive they will dim or the right light will turn off or sometimes both turn off all together. They will come back on if I turn off and back on the headlight switch.

Car was in motion, 55 mph on highway going straight, had been driving one hour. Smoke started filling the rear hatchback area, coming from the driver's side of the cargo-area floor. Pulled over and flames came up. Doused it with water. Upon inspection the sks sensor (remote control door lock sensor) had burst into flames, burning the plastic and other components around it.

The electronic dashboard combination meter (speedometer, fuel gauge, and odometer) is defective and intermittently fails to turn on. The dashboard is blank. We have no ability to discern vehicle speed, fuel level, or number of miles driven. Typically, the display will not turn on when the ignition is started. After several miles of driving, the combination meter eventually turns on. The problem seems to have become worse now that the weather is cold, with the combination meter taking far longer to turn on -- after 10-12 miles of driving. Toyota has issued a TSB on the defect and has extended the warranty for this defective part, but our vehicle falls a few months outside the extended warranty period. Don wood Toyota of athens, OH and Toyota motor sales USA refuse to replace the defective part under warranty. A little internet research indicates that this is a common defect in certain model year Prius.
Toyota Prius (2008) - fire after minor accident (battery fire) after a fairly standard rear end collision (25-30 mph), my Toyota Prius caught fire and burst into flames. I was stopped at a red light on a city street in chicago, IL when the accident occurred, my vehicle was not in motion. Within minutes of impact (to right rear of car), the responding police officer saw fire under the car (began in rear) and the fire dept was called. The fire travelled to the front of the car and the car has been deemed a total loss. The police and tow company believe this was caused by the Prius battery and these cars are very unsafe to be on the road with this condition. There has been no related recall on this vehicle, but it's incredibly unsafe and I'm very happy I was not traveling with my children at time of accident. I appreciate you taking time to review this case and taking steps to ensure Toyota addresses the issues with the Prius vehicles. I've attached the police report and photos of the car fire (I also have video of the fire, but the file is too large to attach on this submission - available upon request). No major injuries - I experienced soreness / headaches from impact/whiplash and saw my doctor following accident (no major injury). Please review and let me know if I can provide anything else / answer any questions. Thank you in advance! frederick gundrum.
Rodent damage to wires on main harness. Perhaps due to soy-based wire coatings? also rodent damage in ac intake and evaporator core. Car was parked.
The headlights are prone to turning to off randomly, sometimes one side, other times both sides. After turning them on/off at the steering column they will come back on for a while then the issue starts over. This problem occurs with the vehicle either moving or in the stationary mode. No headlights when driving at night is a definite safety hazard. So far, Toyota refuses to honor a fix!.

When vehicle is started no dash lights for fuel gage, speedometer, odometer inoperable due to faulty combination meter. No recall just extended warranty that Toyota will not replace.
My display has gone black multiple times. Start the car and there is no display, no rear camera. . . . A major safety concern I have found out through the Toyota forum. So I have to go to the back unplug something from my battery - or my wife or daughter. Not safe by any means!! no recall for this fmvss issue. Unacceptable.
I am writing to you about my 2008 Toyota Prius. . . The dashboard will go completely out while driving on the hwy when this happens you have no complete dashboard and the ignition will not operate. I have reached out to Toyota and was told my 9 year warranty is out of date and this my problem. . . Very unsafe component to have fail while driving.

My headlight passenger side keeps going out after a few seconds of turning on. This keeps me from driving at night. My computer controls on my dash board that works the ac. And displays the information about the car does not work. My abs break light will not go off. This has affected my breaking system on my car. All of these items I have mentioned all occurred while I was driving the car.
Toyota Prius combination meter not working for 2 days when I repeatly turn it on and turn it off. . . . Then works one day then is not working now---I can't see the instrument panel and how fast I am driving and then I can not shut the car off for several minutes. . . . Very unsafe. And I just had the car serviced for a messed up battery. This is a used car that I bought to replace the 2001 Toyota Prius that was rearended in Dec 2016 then the dealer sold me a junk car in April 2017 now having to fix all these problems. I will sell this car as a piece of junk to the junk yard as strap metal because that what it is. Very unsafe and the NHTSA is allowing this to happen. Started on 08/22/2017 & 08/23/2017 & 08/25/2017 I can't see the panel.
I believe its a glitch in the car's computer. At unpredictable and intermittent intervals the electronic heads up display does not operate. This leaves me with no speedomoeter, no fuel level indicator, no bright or dim indicator for the headlights, and the cruise control does not work. During the incidents the car also might not respond to the power off button, so it keeps running. This problem might last for a day or two and then it starts to work again.
The main display/touch-screen in my Toyota Prius stopped working while it was parked and the engine was off. The device worked in the morning when, but it would not work that afternoon when I re-started my car. The device also stopped working at that same time. As a result, I am unable monitor the hybrid system; access the climate controls (there are some controls on the steering wheel, but, since I cannot see the effect, I am very reluctant to touch them fearing that I will lose what little a/c I have now); the back-up camera; the blue-tooth (for my hands-free cell phone); the navigation system; vehicle maintenance info; etc. I have driven my vehicle since, and now my vehicle flashes the symbol indicating the absence of my key-fob (even though I have it with me in my pocket) unless/until I push the key-fob into its slot in my Prius. As a result, in addition to all of the other things I am no longer able to access, I am now very concerned that my Prius is going to malfunction while I am driving down the road due to its failure now to recognize the presence of my key-fob. In researching this issue, it is apparent that many other Prius owners (several year models) have had similar issues with this device. When I took my vehicle to Toyota to have them repair/replace my device, the asst. Service manager informed me that Toyota did not make the device, that they do not have any replacements, that the manufacturer also does not have any more replacements, and that my only hope was for them to disconnect/remove the device, send it off to a 3rd party to "hopefully repair" my device, and that this process will take up to 2 weeks (while I drive without it). It is inconceivable to me that Toyota is unaware of this problem (since all of their supply and the manufacturer's supply of replacement units has been exhausted). Please help.
1) the tablet information screen is so large and the instructions so complicated that you have to take your eyes off the road for a long time just to regulate hvac and radio 2) the car goes completely dead randomly after driving it. Must be towed.

The Prius odometer stopped at 299999 and won't record more mileage. However, the trip odometer continues to register miles, so it seems clear the mechanisms are working to collect miles. The problem this causes is that some states view this failure to move on or reset at 000000 as an inspection failure. Should not be a designed failure, as previous comlaint indicated since this is a digital readout.
I was driving on the freeway at about 70 mph when the "check hybrid system" light came on and the car lost all power and ability to accelerate. It completely began to descend in speed and within 2 minutes came to a complete shut down. I could have easily been rear ended had I not moved to the side of the freeway as quickly as I did.
The main display randomly goes out after starting the car. My Prius was at 82,000 miles when the problem began. I contacted the dealer, central florida Toyota, who informed me it's a bad euc module that controls the display for speed, fuel, what gear you are in and if your head lights are on. All of those items are extremely important when operating a vehicle and if not working could cause an accident. I contacted Toyota corporate on the issue and was provided a case number. They informed me the 9 year out warranty had expired since my car left the lot in Sep. 2007. Toyota corporate nor central florida Toyota would offer any assistance on the part, labor or even proving a loaner car while service was preformed to correct the issue. I was informed from central florida Toyota it could take up to 6 weeks for the part / labor to be completed. Please open an investigation of this part, as research has shown this to be a known bug with the system. Due to the tools this module controls (speed, gears, lights) this could cause a catastrophic accident. Please hold Toyota accountable to keeping their customers safe. As a long time Toyota owner, I am extremely disappointment in their handling of the situation. I will be happy to provide any information needed to help correct this issue for all Prius owners that have or have had this issue with no assistance from Toyota.
Car headlights will intermittently go off during nighttime driving. This issue has occurred on multiple occasions.
