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.

problem #175

The electronic dash (heads up instrument display) on our 2007 Prius has intermittently failed to light over the last year. Yesterday, it failed and also wouldn't turn off. We always use the remote (keyless) ignition system. But, after the failures yesterday I put the electronic key fob into the hole in the dash thinking that might help. Instead, I couldn't remove it. I tried every combination of pressing buttons (the park and power buttons) and other controls, brakes pedal, shifter and it still wouldn't shut off or light up the display. After holding the power button in for an extended amount of time, it turned off and ejected the key fob. But then the car wouldn't light up the instrument display or start. This morning, again, it would not start. I was told by an experienced Prius mechanic (also an owner) that these were classic symptoms of a failing power amplifier for the display and that it was a "secret warranty, " a voluntary repair to avoid a government recall, but that Toyota would only do it for 10 years. The dealer refused to do it under warranty even though the symptoms began before the car was 10 years old. They told me the recall was only good for nine years. They want $765 for the repair. It strikes me that this is a safety failure and should be covered, period. With no indication of speed or other functions (ABS function, traction control, etc.), or to turn the vehicle off, it is unsafe to operate the vehicle. The various failures, including loss of cruise control while in motion, took place when the car was cold and when it was warmed up. At rest and in motion.

The contact owns a 2007 Toyota Prius. Without warning, the instrument panel cluster failed and the gauges failed to properly function. The vehicle was taken to a dealer to be diagnosed. The manufacturer was notified of the failure and indicated that the time frame had expired for the contact to receive the warranty extension campaign and provided no remedy solution. The approximate failure mileage was 115,000.

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!

My wifes 2007 Prius headlights continue to flicker while driving at night. Then one side or the other will go out. The headlights have been inspected by 2 certified mechanics neither can find any faults in the headlights or bulbs even applying contact grease to assure electrical continuity. Attention NHTSA administrators ( this certainly could become a deadly problem.) we have had both lights go out simultaneously. The driver must immediately turn the light switch off then on to restore lighting. I hope they never fail to re-light!! of all the problems- attention surely must be given to these lights. Almost a thousand complaints many people keep taking this problem to the dealers, only to have it repeat itself? immediate action is required by the NHTSA.

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.
