Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

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).

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.

The rear hatch release on my 2007 Toyota Prius has begun to deteriorate and turn into a rubbery and sticky black mess. This issue interferes with the use of the hatch as the rubber not only gets on your fingers but appears to be blocking the release mechanism. The deterioration started during the summer.. the issue has worsened and today I was unable to open the rear hatch whatsoever.

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.

I started my car and as I was driving noticed no instrument lights on dash. I tried turning engine off (2 step procedure) and was unable to stop engine, unable to remove keys. I was stuck with a car that was running, an inability to lock the car because it did not recognize the commands. I tried calling the closest dealership and was passed from one person to another without answers as to what to do. I then called the dealership where I had purchased the car and they were able to tell me how to get the engine off - and they said there had been a recall on the instrument cluster. I had not been notified. I regularly have my car serviced at the dealership - as recently as 3 weeks ago.

My 2007 Prius has the hid (high intensity) headlights. Sometimes both headlights go out at the same time and sometimes just the passenger side headlight goes out. I originally thought that the problem was the bulbs so I replaced both bulbs just a few weeks ago with new bulbs, but the problem is still occurring. Sometimes when I turn the light switch off and then on again the headlights come on again. It seems to be a random occurrence but it is happening more and more frequently. This is a very dangerous situation especially when driving at night.

While driving the left headlight went out I turned off the lights and back on, the headlight came back on. Since this first incident the right headlight done the same while driving. Both headlights have turned off at the same time while driving. It seems like this is a wide spread issue with this year of Prius. The dealership will currently only replace the bulbs at a cost to me of $1250. The bulbs don't seem to be the problem, considering they work most of the time. If you can turn the lights off and back on again and the light(s) return to working state, its seems to be an electrical controller board problem.

My headlights keep going out. Both headlights will go out at once. I've replaced the bulbs which did not change anything. I also contacted Toyota multiple times, all incidents ending up in them telling me they would do nothing about the issue, it's not a recall and will not be a recall and it's my responsibility to take care of. Even after I pointed out the multiple articles I read of Toyota reimbursing and extending the warranties for this issue. Along with the class action lawsuit. I've long extended the warranty because I bought the car used. It had over 30,000 miles on it when I bought it. The Toyota dealership is even less of a help! going down a dark highway at 65 mph and both headlights going out is insane. Not to mention being pulled over multiple times for the headlight(s) being out. This is one of the worst safety hazards a car can have and should recalled and every Prius owner should have this issue taken care of!

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 rear latch of my 2007 Toyota Prius has degraded to the point that it is inoperable. The rear latch release has melted to the point that it ends up all over my hands when I attempt to open the rear hatch and does not open. I am unable to open the trunk. This is a major safety issue. I have two children under the age of 5 who are strapped into car seats. In the event of an emergency, the rear hatch may be the only way to access them. Obviously, if I am unable to access them, the failure could result in serious bodily injury or death to the passengers, including my children. I have contacted Toyota requesting that Toyota correct this problem on my car, but they have told me that: 1) they are unaware of the problem; 2) my car is out of warranty and I do not have an extended warranty; and, 3) they will not fix the car. Do people need to get injured or die before Toyota reacts?

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.

The rear door latch cover material has deteriorated and the latch is no longer operating as expected. The rubber material is a soft gummy consistency and the latch mechanism to the hatchback fails to release allowing access to the rear storage area. This area contains the spare tire.
