Toyota Prius owners have reported 515 problems related to electrical system (under the electrical system category).
Hybrid battery exploded in car, I thought someone shot at me or bomb went off in car. Later I realized there was a problem with the hybrid system. I couldn't get a hold of Toyota or representative of Toyota, I took battery out so there wouldn't be a fire. When I opened casing up I saw the damage where a cell or two exploded inside hybrid battery pack. When I finally got to talk to someone from Toyota 4 days later and told them I removed the pack so it wouldn't start a fire in car and for the authorities to inspect battery, they started yelling at me for driving the car and removing the battery. I said this is a safety issue, it can happen to anyone. It has affected me, my child and dogs hearing as a result and negligence of Toyota. I was scared and frightened by Toyota's response and the call back after I yelled at the and hung up. I got a call back from them where I was threatened by a man. I thought Toyota cared about customers, not to threaten them, and to tamper with evidence and hide a safety issue.

The rubber cover to the outside truck latch has melted completely in hot florida weather and has become gooey to the point of dripping onto my license plate. The truck is very difficult to open and sometimes I am unable to lock or open the car because the trunk is not all the way closed. This is a safety issue because if I needed to get into the trunk to get a spare tire I may not be able to. Given many other reports of this issue dating back to 2007 models, Toyota should stop using this type of component and should recall this item and fix it with a different material so this does not keep happening. I am also concerned the exposed latch will cause electrical damage to the trunk or lighting because of severe rain that often occurs in florida where this problem seems prevalent.

I went from a stationary driving position, to driving off at 20 mph down a 3 lane highway, suddenly a few seconds after, all these lights came fashing warning lihgt, brake lights, abs light and a loud beeping noise. I had no power, no brakes…. . Fortunately there was nobody in front of me or close behind and I could veer into the side of the road. I turned the car off totally. And then tried to turn it back on again to see what would happen, and all the same lights and beeping noise started again. Had the car towed to Toyota in santa monica. There was no manager on site. One of the service guys said he would have it checked. They refused to give me a temporary rental or substitue car - they said they would give me a ride to a rental place! this is 11 a. M. The following morning. The manager at the dealership is stil not there. The associate called me and said I could pay to have it repaired !! I have called the Toyota customer relations service, who say they will get back to me in "a day or so". Aside from my life and others lives, being put in total jeopardy by my cars' failure, I think the lack of urgency on this matter is appalling. There may be other Prius cars that will have the same failure, and people killed.
There has been no injuries or vehicle damage. I left off total repair cost because the repair shop has not finished solving the problem. In 2013 I started have having headlight problems and have it about three months since. I have replaced the headlight bulbs several times on both sides. One time the headlights would operate opposite( one side would be high beam only and the other would be low beam only and when switching the switch inside to high beam the headlights would switch as to what they did only. On wed 8/20/14 the low beam quit working. I earlier purchased a new plug and 2 new bulbs in case I had a problem. I took the car to an independent repair shop( my only Toyota dealer in my town can not be trusted) where I live. He installed the new plug and we tried each of the two new bulbs and they exhibited the same problem - the low beam was just a spec of light; not enough for the low beam. He tested the voltage in the ground side of the plug and the fuse position in the fuse assembly and it lit up his voltage tester with a spec of light. He had no idea what system sent the voltage to the low beam side for the passenger side headlight. I am taking the car back on wed 8/27/14 to finish the job.
Rear hatch release latch has been getting stick to the touch and increasingly difficult to open. Tried cleaning the latch and discovered that the rubber covering the latch seems to be melting. Checked online and discovered that this seems to be a common problem and, if not corrected, will likely result in latch release switch failure. The location of the rubber latch release cover protects it from direct sunlight and there seems to be no reasonable explanation for the failure of this part other than a defect in manufacture.

As the navigation/gps system was being used on a long trip, the backlight suddenly burned out. Upon touch, the screen was extremely hot. (it did not cool down until appx. 1 hour after the backlight had malfunctioned. With the backlight not working, it renders the entire navigation system, bluetooth, back-up camera, audio system/cd player useless and not useable. (entire screen is black. ) although the vehicle is only 2 1/2 years old, it is no longer covered under the manufacturer's warranty. The part costs between $2400 and $4500 to replace. Numerous complaints have been recorded on various complaint boards about the same issue on 2010 and 2011 Prius cars by consumers.

The tail lights intermittently go out when driving at night, while the brake lights are fine. It is related to a problem with poor quality tail light sockets on this model and year. Replacement bulbs do not address the problem. This seems to be a common problem, not unique to my vehicle only.
In 2007, we purchased a certified used Toyota Prius 2005 with 13,298 miles. We have owned this car ever since. We currently have about 81,000 miles on this vehicle. Brake failure incident on June 30, 2014, I was driving the 2005 Prius slowly (10-15 mph) along a roadway located in a tecumseh, mi city park: ¢as the car approached a local street, I braked for a stop before making a right-hand turn. As I engaged the brake, the abs system red light appeared, the red brake light was lit and the related buzzer was activated as well. Â¿¢as I braked, my right foot went all the way to the floor. I experienced complete and total brake failure. Â¿¢I finally stopped the car with the emergency brake. Â¿¢I drove the Prius very slowly over the two miles home, using the emergency brake to stop as needed. Â¿¢my wife and daughter were riding with me in the car and witnessed the incident. On July 1, 2014, I contacted aaa and arranged to have the car towed to a repair shop in ann arbor, mi ¿ 30 miles away. After a week, at the repair shop I arranged to have the vehicle towed to the local Toyota service facility. Over the previous five months, I experienced another curious problem that may be brake related. When braking on bumpy roads (we have horrible pot holes on many major streets and roads) or curb cuts, the car accelerates ever so briefly. The feeling of loss of control is very disturbing. It remains to be seen if this problem is related to the brake failure noted above. There were no injuries as a result of this brake failure. However, I had just returned home from business in a neighboring community 35 miles away. I often drive backcountry county roads with posted speeds of 55 mph. If I had experienced the brake failure then, I might well have been killed along with others.
Smart key was in car and car locked anyway from door activation. Car isn't supposed to lock if key is in car. I called dealership but they offered no assistance. A second key had to be brought from home and used to gain entry. Fortunately, no child or animal was in car as weather was in upper 70s so excessive heat could have been a problem.

The hid headlights on my 2007 Toyota Prius appear to be defective. When I turn the lights on initially, they both illuminate, but the lights dim progressively, and after several minutes the lights are essentially dark. This occurs in both headlights and started only this month. This is a significant safety issue, as it is very dangerous to drive without working headlights (particularly when one assumes that the headlights are working since they turned on initially). It is my understanding that the issue is beyond replacing the hid headlight bulbs; according to the repair shop I visited, there may be a defect with the hid electronic control units (ecus). I understand as well that this is a defect that has occurred in numerous Toyota Prius vehicles and that Toyota in 2011 agreed to a settlement of a class action lawsuit that provided some repair coverage for certain owners.
The dashboard light will not come on and I could not read mileage or how fast I was going. Eventually, car shuts down in motion. Took it to keyes Toyota in van nuys, CA. They acknowledged there was a defect and recall and would fix it after a few days they are telling me I have to spend about $4000 to get it fixed because there are fuses burnt and cannot determine what is causing this.

2014 Toyota Prius. Consumer writes in regards to engine failure. The consumer stated a brown colored alarm appeared on the dash, which flashed on then off, as the vehicle started to slow down. If he tried to accelerate, the light would come on, but no response to increase speed. He managed to pull over, and stopped the vehicle. After a few seconds, he tried to re-start the engine and was successful. The dealer was unable to duplicate, the problem the consumer experienced.

This complaint has not been qc¿d. The contact submitted an email and requested that the official ivoq be written verbatim to the email. Kmj I have multiple situations with my Toyota Prius 2006 in the beginning of may 2014 I a loud beeping noise filled the car. The system had multiple lights displaying showing including the emergency brake light ( while I was driving), abs,vsc, a red triangle with an exclamation point in the middle, etc. As, this was happening car immediately started slowing down and I was forced to pull it to the side of the street. This same thing happened to me three other times while I was on the freeway. One time I was driving home from work and my car again started decelerating while I had multiple cars around me on the freeway. All of the lights were displaying, I put my hazards on and was forced to move to the side of the road while I was almost hit by the car behind me because my car was rapidly slowing down. I took the car to the dealership service center and they didn't know what the problem was. They did a diagnostic test, multiple test drives, but at that time they didn't know. So they told me to drive the car home and come back if it happens again. Within the week I was exiting off of the freeway with my children when I start hearing the loud beeping noise, all the lamp lights came on, and as I am waiting in line to exit the freeway onto a busy street the car stops. I panicked, put on the hazards, the car wouldn't allow me to shift it into drive it had moved to neutral on its own. I turned off the car, turned it back on and was slowly able to move the car. This time I took pictures of the lamp display to show the service members as well. My children, myself, and other drivers could have been seriously hurt! the Toyota service center told us we have a bad computer, the problem is with the ecu, and the car went into a fail safe mode.

The buttons on the steering wheel began to stop working. One by one, each began to fail. I wasn't too worried since they're simply the climate and stereo controls, however, as I began researching all signs pointed to this being the "clock spring" assembly. This also controls the airbag and is a huge safety issue. I went to the dealer who confirmed and said this would cost $500 to repair. When I asked about the airbag they said they do not recommend that I drive the car because the airbag "might not work" anymore. After seeing a sufficient amount of posts here, I wanted to also add my feedback as it appears this is far more widespread than just an isolated incident. I have drive 4 other (non-Toyota) vehicles for well above 200,000 miles and never had this issue. My father (automotive mechanic for another car brand) said he's never had anyone come in with this issue before. Considering that toyta prides themselves as having safe vehicles, I would hope that they consider a recall on this life-threatening part failure.
Wednesday April 30 2014 I went to church, when I came out and got back in my car light was out. They were burning.
The low beam bulb lamp came loose from its housing - melting the socket, and while still "working" did not provide proper illumination for night driving and perhaps posed a fire hazard. Upon taking to the dealer, they replaced the entire unit (for $720. 08) and have ordered a retrofit bracket (it is on back order) that they will installed to prevent re-occurance. Seems there is a problem - they know it - but the public bares the cost and possible safety issues associated with the problem. They are not taking any proactive action to install a retrofit bracket to prevent the working lamp on the opposite side of the car from dislodging and causing a similar problem.

Vehicle was stopped at a red light with engine running. Engine suddenly stopped and would not restart. A check hybrid signal appeared on the dashboard and vehicle would not move in the middle of a busy intersection. It had to be towed.
Both of my Prius headlights went off, for no apparent reason, while driving down a busy highway. Flicking them off and then back on brought them on again, but this is a dangerous situation. This has happened one more time since then. This could cause a serious accident. Toyota is unable to isolate the problem. The company wants to replace the bulbs, but this doesn't fix the problem, according to many other people who have had this problem. Replacing the bulbs or adjacent parts can cost hundreds of dollars, which is not sustainable. It seems that a recall is in order.
The back door latch of my 2007 Toyota Prius has degraded ("melted" almost). It no longer functions properly, and I am unable to open the back hatch door. Sometimes it required considerable effort and perseverance to get it open. I cannot open it anymore as the latch broke. I am concerned that in the case of an emergency, I will not be able to get the door open. This is a major cause for concern and it is a serious safety hazard. Blue 2007 Prius in cupertino, CA.
I was returning home from a trip with a friend and driving on major freeway late at night, very dark with little visibility in a rural, unlit area. . All lights in vehicle shut down while driving 70-75 mph. We could not see anything even the road, was like driving blind and very frightening trying to navigate the Prius off the road safely without getting hit by other vehicles. Once I stopped the vehicle off the side of the road in the far left lane we turned the vehicle off, but left the hazard lights on and let the vehicle sit for a few minutes. We started again, lights came on, and I drove the vehicle another 100 miles without any incident until we entered the city. I had a similar problem driving the 12 remaining miles home, but the front yellow lights worked and I had the hazard and brake lights working. The city lights improved visibility. I took the vehicle in and the only problem they could find was with one of the headlights. I was told I needed to replace both. I can't emphasize how dangerous and frightening this experience was for my friend and I, still unsure how we avoided a tragedy. I would like the NHTSA to investigate and make a recommendation to have some type of warning in the vehicle.
Headlights, go on and off on their own. Sometimes only one will go off, sometimes both. Happens with high beams as well. Lights come back on if I switch them completely off and then on again. May stay on for 30 minutes, may only stay on for a couple minutes. Very dangerous as the lights have gone off at night time causing loss of visibility.
Brake (red color) warning lights appear while driving at 55 mph; yellow color indicator on abs, vsc. Once these warning lights appear, I somehow lose 25-50% of my braking power. Not sure what is wrong despite getting brand new wheels, replaced all-new rotors, brake pads, oil and filter change. This is the 5th time it has happened in the last few weeks. Toyota should be held liable and to replace the full cost of any necessary fixes to the hydraulic brakes or run a diagnostic of the entire vehicle's electrical or brakes system or anything that leads to the dashboard warning lights at 100%. This will be a serious issue because it can lead to serious accidents if owners of this vehicle experience the same issues.
After driving for a combined time of 4 hours in a 5 hour period, my wife left a store she visited off zebulon road and I-475 near macon GA. When attempting to re-enter southbound I-475 the car failed and would not accelerate. A few seconds after the drive system shut down and would not restart. The dash indicators said check hybrid power system. The car was towed to a dealer rogers Toyota in macon GA, where it now is. The dealer says that the problem was the engine control module though the inverter is being replaced under an existing recall issued last week. It is not clear if the engine control module is covered by the recall.
For the second time in a year, the electronic display panel on my 2007 Toyota Prius has gone completely dark I. E, inoperative when I started the vehicle. This panel displays the vehicle speed, gas guage and various status & warning lights. The car still is able to be driven even though the display panel does not work, which is a hazard. The first time it happened I had the Toyota dealership's service dept. Look at the car and they could not reproduce the problem. This time I noticed that the interior door light was lit. However no door was open. While the vehicle was powered, I open and closed every door including the rear hatch. The door light remained lit. I then hit the power button to power the car off and then back on. The interior door light went out and the display panel came on, resolving the issue. I've tried to replicate the problem by opening a door and powering up the car without success. There has to be another factor involved that causes the display to fail to operate.
When the headlights are on, the speedometer does not display when the dashboard lights are dimmed. All other displays dim, but the speed of the car is no longer displayed.
