Failure Date: 12/08/2014

Vehicle does not properly start-up and ends up in a state where it cannot be turned off. I pushed the ignition button, which normally quickly turns green and normally the car would start. Instead, the car goes into a state where the dashboard illuminates, an error icon is displayed, and the power cannot be turned off. I hold down the power button for over 5 minutes before the car finally turns off. During this time, the power button is amber, the dashboard does not show the car is in any gear, and the green light on the park button is on. The power button absolutely does not function, nor does the gear selector. My understanding is that holding down the power button for 5 seconds should absolutely turn it off, this is not the case. This has happened on three occasions in the past week.

The hatchback lift has deteriorated and no longer works. The Toyota service representative quoted me $570 to replace it, stating it could pose an electrical system safety issue. No damage has occurred and since it is keyless . . . How does this happen? the clear coat has degraded only on the piece of metal that encloses the hatchback's lift mechanism and started flaking about the same time that I noticed it was getting harder and harder to lift the hatchback. Could these two failures be related? when these problems started several months ago it didn't occur to me that there might be a connection. The service rep ignored my question about a possible relationship.

I was driving home last night and various warning lights came on. Within a short time the vehicle lost all power (entered a failsafe mode) and the hybrid system shut down while I was driving. The result was a complete loss of power and the vehicle came to a stop in traffic. I was close to the curb and turned on my emergency flashers. Called a tow truck and will take this to the dealer. I called Toyota customer service to see if others had experienced anything similar and they had no access to any information about other customer's experiences. They did say that there are no active recalls for this make and model year. A recall for the 2010 - 2014 Toyota Prius was issued in February 2014 for what sounds like a similar problem. While this wasn't a life threatening issue for me last night, in a press release drivers who've experienced similar issues were warned to get out of their vehicles because they could be in danger from being rear ended.

At approximately 65mph a red triangle warning light appeared on the dash panel accompanied by a yellow circle. The parking button was flashing and a pink cartoon car appeared on the display. The car was running fine so I continued till I reached my freeway exit. At the bottom of the exit I had to stop for a red light. The exit is dark and has a sharp curve. Upon stopping the car the transmission locked and the engine shut down. I was unable to start the engine and and the car could not be pushed out of the way due to the transmission lock. Frantically I had to get a flashlight and wave off oncoming traffic. It was very dangerous. After a few minutes I retried the engine and it started allowing me to get off the ramp and get home. The warning lights stayed on. I took the car to the dealer the next day and after they tested everything they said that there was nothing wrong. Next time I might not be so lucky.

The back 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 easily. Sometimes it requires considerable effort and perseverance to get it open. 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.

2007 Prius dashboard lights malfunction - completely dark. See nhsta # 10544698 and many other complaints regarding dsashboard lights/cluster going completely dark and engine will not shut off. This is an extremely serious safety issue and dealerships will not repair for free. The part needed is a combination meter/cluster that costs around $1000 to repair from the dealer. Please everyone - push for national recall as this is an extremely dangerous safety issue.

Failure Date: 09/25/2014

Today, when our 2005 Prius was turned on, the dashboard lights, including the odometer and speedometer, and all of the dashboard warning lights, did not illuminate. Additionally,the Prius would not turn off by pushing the button on the dash. A google search revealed a known problem with the combination meter display that controls the dashboard lights, including all of the safety warning lights, that prompted Toyota to issue a warranty enhancement, covering this defect either for 9 years from the date the car was first put into service or until September 30, 2013, whichever is longer. As it turns out, my Prius is outside this warranty extension by three days. I called the national Toyota customer experience center at Toyota and was told, because there was a warranty extension, no further extensions can be granted and I am responsible for the repair of this defect. I have an issue with this due to the fact the module in question is not user-affected or serviceable in any way. If its engineering and/or manufacturing is such that it only lasts 9 years, and it is crucial to the operation of the car, and the display of system warning lights that reflect any problems with the supplemental restraint system, braking system, hybrid system, etc. I have an issue because this electronic device makes the car inoperable and many people with Toyota Prius vehicles, from model years 2004-2009 are experiencing this problem. Shouldn't non-serviceable, critical parts to the operation of a car, that display the status of safety-related systems, last more than 9 years? there will be consumers who opt to drive the car anyway, which could lead to injuries and death, depending on the status of their safety-related systems, which they have no way of being able to see when this defect appears in their cars, at the time of a crash or need to brake in an emergency.

2014 Toyota Prius. Consumer writes in regards to push start ignition system. The consumer stated the vehicle belongs to his parents. He noticed the engine turned on by itself. He was able to open the door and noticed the power push button was lit which indicated the engine was on. The screen on the center console stated no key was detected. He pressed the power button to turn the engine off. The dealer informed the consumer, if he walked away from the vehicle without turning off the ignition, the vehicle would stay on. The engine turned on because the vehicle was in battery mode to replenish the battery power, when the system detects the battery charge has dropped below a certain level.

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.

My 2009 Prius has a non-navigation mulit-function display that controls everything from sound to temperature to hands free phone. Plus, it functions as the rearview camera display. In August of 2014 at about 80,000 miles the screen began to turn off spontaneously while driving (if it turned on at all. ) I have read many reports of this happening to the 2009 models. I am concerned most about the rear view screen because this model of Prius has large blindspots and I relied heavily on this screen.

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. ¿¢as I braked, my right foot went all the way to the floor. I experienced complete and total brake failure. ¿¢I finally stopped the car with the emergency brake. ¿¢I drove the Prius very slowly over the two miles home, using the emergency brake to stop as needed. ¿¢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.
