Toyota Prius owners have reported 667 problems related to electrical system (under the electrical system category).
I was sitting in the passenger seat of the car while it was parallel parked. I pressed the push to start button to turn on the battery so I could charge my phone. There was no one in the driver seat. The car turned completely on when I reached over to press the button. Not only did the engine start, but without anyone pressing on the breaks the car released itself from being parked. The car started rolling backwards into the car parked behind me. I have no explanation about how this happened. I have been reading into it and apparently it's a defect of the 2015 and older models. When the car started rolling back I also started pressing both the park and push to start buttons to turn it off again. I've never felt so unsafe in a vehicle and goes to confirm that park and push to start should not be buttons!!! it makes the vehicle much more dangerous not being able to override those commands when it chooses to go on its own.

Low beam headlamp bulbs fail repeatedly in less than 6 months. This happens regardless of bulb brand or model. I have had these professionally installed at multiple shops. Happens on both sides, but the latest is on driver side.

I have driven people for a living for over 30 years. I bought a Prius because of fuel costs. A month ago while transporting passengers, my power brakes go out and my dash lights up with abs,brake, & traction control warning lights. I take it to the Toyota dealer who charges me $111 to tell me I have a brake problem and that it will cost $4418 to fix it. Code # c1391; they recommend replacing the master cylinder; and booster pump assembly saying there is an abnormal leak down of the brake accumulator. This is insane. I cannot afford to fix it and must continue to work to live; therefore driving about 200 miles/day with hydraulic only brakes. My research indicates there was a major recall for this exact problem on the 2010 model. The dealership and Toyota corporate both say my vehicle was not part of the recall. I feel as though it should be since, obviously, the problem has not been solved. I am not alone, as many owners on Priuschat have the same problem. This is a major safety concern to not only myself, other vehicles or pedestrians, but also my passengers. An expanded recall is necessary and warranted. Anything you can do will help and make us all safer. .
On 05/25/2016 at about 9am, while in motion at a rate of speed approx 25 mph on a street during construction (don't know if the bumpy road had anything to do with it), the change oil soon light appeared and seconds later all the lights on the dash came on with the message to check the "check hybrid system" . I tried to stop the vehicle and it kept accelerating. I pressed on the breaks really hard and the traction control light kept flashing on and off like crazy but it barely had any impact. Although the vehicle slowed, it did not come to a full stop. I ended up hitting the vehicle in front of me. Thank god it was a truck and as able to stop the car from moving further or I could of ended up in the middle of an intersection. After the collision, the car would not stop although the park button was pressed and light was on. I even tried turning off the vehicle and the vehicle stayed on and in drive. I ended up in the hospital and don't know how it eventually got turned off but that was very frightening. I had my children in the car. On impact, the seat belts did not even tighten.
My headlight caught fire and severely burned my car. I was driving down the road on a city steet and saw a wisp of smoke and pulled over into a store parking lot. I had no warning lights indicating anything was wrong. It began to smoke more, and I cautiously opened the hood to see a fire coming from my drivers side headlight area. Within seconds there was a blaze, and it took 3 fire extinguishers to put it out. The fire department confirmed that the fire originated from the headlight. I had previously experienced problems with my headlight becoming dull and cloudy. An earlier NHTSA investigation did not result in a recall. I think it's the same problem with the headlight, only much worse. If there were not multiple fire extinguishers available the car could have easily exploded before the fire department arrived. It could have easily caused harm to other people.
The cd player burns the cd image label. When entering 4 cds into the changer the cd in the 4th position burns almost the entire image label. The other cds had the image paper burned on the outer 1/4 in of the label. I reported this to the Toyota dealer on may 1, 2016. On may 16,2016 I dove from wilmington ohio to lorain ohio, 3 hours playing 4 cds continuously. This caused the heat in ghe cd player to increase and burn the cds. The cd player feels very hot to the touch after use.

Mice invaded my car. Trapped 6. Found nests in engine area, under trunk, inside hood felt in glove compartment in a water bottle. The smell does not leave after having car detailed and steam cleaned. Toyota should take care of this. Not the consumer problem. My car was driven every day and inside a garage.
Electronic door locks continue to fail. I have taken my Prius back to Toyota two or three times to fix broken electronic door locks. At that time, vehicle was under extended warranty and the cost to replace the electronic door lock was covered. Vehicle is no longer under warranty and Toyota is quoting over $400 to fix. The fact that this continues to happen (and to different doors) leads me to believe there is a known defect in the electronic lock mechanism. I do see a few other complains of the same issue. This represents a real safety concern as the affected door remains unlocked while driving and can be opened while vehicle is in motion (such as by a child). This is also a theft concern as the door does not lock unless walking around to the affected door to manually lock it.
Without warning the dashboard stopped working. The car was stopped and power button was pushed at the time when fact occurred in a very isolated place with no cell phone service an little chance of any other car passing by. The car does not display anymore speed, mileage, fuel level and gearbox position, although the car was otherwise driveable. Warning lights are not working anymore also. Backup camera and lights also stopped working. Car also does not turn off most of time (the power button might work at random with some insistence). According to information gathered this could have been caused by a faulty combination meter, which Toyota was servicing for free for some time owing to a high failure rate.

Vehicle lost power, stalled while driving at highway speed; "check hybrid system" displayed on dash; required replacement of inverter and intelligent power module.
Took my Prius into the dealer today for service. Later, the writer called to tell me that the mechanic had found a build-up of link and dirt that might lead up an overheating or other issues with the battery pack beneath the rear seat. I paid approximately $350 to have the battery fan serviced and later discovered that this issue is under investigation by the fhtsa. I can provide a copy of the now-paid service bill.

The headlights on my Prius randomly go dark. Sometimes 1 headlight and other times both. Turning off the light switch and then back on is a temporary fix. The problem comes back minutes later. This is very unsafe for myself and other drivers on the road. This happened while I was on the interstate going 70 mph last night!.

The contact owns a 2010 Toyota Prius hybrid. The contact stated that while driving at 40 mph, the temperature gauge began to indicate hot. The contact stated that the temperature warning light illuminated and the vehicle emitted smoke. The vehicle was parked and diagnosed by an independent mechanic, who stated that the water pump needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 201,000.
Dash goes completely blank while in motion and car will not turn off.

Digital dashboard sometimes is completely blank for extended periods so that I can't see my speed, fuel levels, odometer, and other info. When I start up it happens and continues the whole time I am driving. It is causing other problems related to the hydrolic braking sometimes as well when this happens.
Check hybrid system car shuts off and can not restart, tried system reset per manual but would not clear hybrid. Towed to dealer, dtc code p3004-800, tech said this was the only code, had recall eoe reflash 04-14-2014 ipm extended 15 years. Car was in motion per wife. (it had been raining) the dtc p3004-800 power cable malfunction.
The car was at a stop light when all the dashboard lights went out (nightime). When I tried to turn the vehicle off, the car would not shut down. This is a known problem to Toyota especially on high mileage vehicles. The car has 217,000 miles (original owner). Toyota issued t-sb-0172-09 as a "warranty enhancement program" in order to avoid an official recall of the problem. Unfortunately, I missed the deadline by 3 months.
Both headlights (low beam) go out at the same time. No apparent issue with the fuses. Replacement bulbs experience a shorter than expected (approx. 6 weeks) life before burning out again.
Headlights continue to burn out. We have changed one or both headlights at least six times since may 2015. This happens unexpectedly, going down the road at night one or both headlights will burn out. When you change them, will last a couple weeks to months. Very scary when going down a two lane back country road at night. Any help would be greatly appreciated.
One hid headlamp will occasionally turn itself off. Turning headlamp switch off for 3-5 minutes and then back on will correct the issue. As one could imagine, very problematic when driving on the freeway at night. Multiple bulb replacements (over $150 each) have had no effect. Dealer recommended full headlamp replacement is over $1000. Research found that many others have had a similar issue, and eventually trace the problem back to the ballast of the hid lamp, which is easily damaged by water from poor design (the ballast is weather-sealed against the engine compartment, but not against the headlamp itself; any water that makes its way into the lamp will run down and pool on the ballast electronics).
Tl-the contact owns a 2007 Toyota Prius. The contact stated that while driving 70 mph, the brake pedal depressed on it's own and failed to accelerate. The brake hazard warning indicator illuminated several times. The vehicle was able to restart. The vehicle was not taken to a dealer where it was not diagnosed or repaired. The manufacture was not made aware of the failure. The VIN was unavailable. The approximate failure mileage was 52,800. Jw.
While driving, the instrument panel combination meter that displays the vehicle speed and other information went blank. After pulling over car, I tried to turn it off using the power button but it would not turn off. After a few tries, I held down power button for 5 seconds and it finally did go to accessory mode, but did not turn off altogether. It took several presses of the button to finally get the car to shut off. I talked to my local Toyota service center who told me that this is a known issue and Toyota extended the warranty for the combination meter to 9 years (t-sb-0172-09). Unfortunately, I was 4 months past the 9 year mark, so it would cost me $1500 to replace the part. I have since talked to two other people I know who have the same model Prius and they have had the same issue in the past year, one of which was replaced under warranty as he had the problem before the 9 year mark. The other was in the same situation as me as it happened after the 9 year mark. An online search shows that this is becoming a very common issue and happening to many just after the 9 year warranty expires, resulting in a lot of upset owners. I did check my files and see that a warranty enhancement notice was sent to me a couple of years ago that states that this issue has been reported by a limited number of owners and that if it does has happened to my car, I did not need to take action at this time. In hindsight, I should not have followed the instructions and instead took my car in and insisted on a warranty repair. I believe that this is a serious safety issue that should be handled as a recall rather than with a warranty enhancement with a limited warranty period. The car has less than 34000 miles on it.
Yet another 2007 Prius with the rear hatch door latch cover that has decomposed rendering the ability to open the door from the outside impossible. This is a defect that is widely documented on various websites. Toyota should be held accountable and correct this defect at their cost. Safety issues: inability to access equipment necessary to repair a tire failure, potential to be stranded on interstate highways, in remote areas etc. I am 69 years old, have had a hip replacement, a comminuted fracture of the patella on the same leg resulting in wire and screws holding the patella together. The other leg has sustained a traumatic injury that resulted in a rod from top to bottom of the tibia, and muscle, vascular, and skin grafts. Crawling inside the vehicle to access the manual release is not the easy task it may have once been; inability to access first aid or other safey equipment in the event of an incident; inability of rescuers to access the cabin via the rear hatch in the event of an accident.
