Failure Date: 11/23/2016

This 07 Toyota Prius dash instrument lights will go out whether stationary or in motion and or not come on at the start of the vehicle. The car can be driven but there is no way to reference the speed or vital functions of the vehicle when this occurs. Also the vehicle will not turn off when the power button is pushed when the dash is inoperative unless you hold the power button down for an extended amount of time. Toyota knows about this issue but the time limit on the unpublished extended warranty that I was told has expired. We bought this vehicle new in 07. This vehicle started doing this recently. This should have been a recall item on this vehicle due to the potential safety issue.

The contact owns a 2005 Toyota Prius. The contact stated that there was a manufacturer service campaign for a wheel alignment. The dealer serviced the vehicle for the repair. Shortly after the repair, the instrument cluster display panel went blank. In addition, the vehicle failed to shut off twice and had to be left running due to the failure. The vehicle was taken back to the dealer where it was diagnosed that the combination meter needed to be replaced. The contact was provided with a loaner as the dealer further tested the vehicle. The manufacturer was notified of the failure and the contact was waiting on their recommendation concerning the dealer's repairs. The failure mileage was not available.

As I was coming back from livermore to san jose down the sunol grande last weekend, my dash lights suddenly went out meaning I had no speedometer or wait to tell how much gas I had and the abs and stability control went out while going 65 miles an hour down a steep hill. Luckily I was able to get home and don't ask me how I figured out to get the car to turn off. I called the one 800 Toyota number and it turns out there was a problem with something called the combo meter on these cars and it had an extended warranty for a total of nine years. My warranty expired they said April 2016. This seems like a serious safety issue that Toyota should cover if they are concerned about their customers safety.

The trunk opener switch on my 2007 Prius no longer works reliably because it is made of a defective rubber which has at this point melted into a goopy mess. This means that the opener switch can become stuck in the closed position, rendering it impossible to open the trunk until the release mechanism of the switch overcomes the tensile strength of the goop. As a cursory google search shows, this is a common problem which Toyota routinely refuses to repair. It is a potential safety issue because a pet or child could be difficult to retrieve from the trunk area if the trunk cannot be opened. An unexpected hazard such as a leaking propane tank or a battery fire in the trunk area could similarly be difficult to mitigate.

Takata recall. My car won't shut off. They say the instrument panel cluster needs replaced. It has been on back order for 13 days so my car is useless. I can't drive it. I paid either 23,000 or 28,000 for it and have kept it maintained. The Toyota place says they have another lady that's been waiting 3 days less than mine. I called California Toyota. They can't tell me anything - but today told me it might be on back order. This is a safety issue. A car that won't shut off is a danger. It could kick into gear. It could damage the motor. A car that you can't tell how much gas is in it can be a problem as well. I can't drive it. The speedometer won't work. This is a problem with safety as if you can't tell what speed you are going you risk tickets. The Toyota place in birmingham has replaced 30 of these instrument clusters. If that is representative nationwide there is a big problem and these cars should be recalled. I only have 150,000 miles approx. On my car. The salesman told me it would last at least 300,000 miles. I had to replace the 4800. 00 battery at 103000 miles. My other gripe is they didn't tell me until 13 days later it was "probably" on back order. I wouldn't have rented a car for 13 days had I known it was "probably" on back order.

While I was driving, the car suddenly made a very loud sound, that did not go away. Along with that, the lights on the dash lit up, the brake light, the red hazard exclamation triangle light, the abs and vsc light. It felt the brakes were not working and I would need to press it down hard for it to slow down. This has happened three times! and each time I took it in to Toyota, their diagnostic tests showed nothing. They think it could be the battery but they did not suggest changing it. The three episodes that happened, luckily no injuries or crashes. But it is very concerning as I feel this will happen again and they have not figured out what the problem is.

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.

On September 10, 2016, while we are driving back to indianapolis from chicago, the left dash screen became dysfunctional and went completely blank. There is no indication of the speed, the amount of gas in the tank, and the condition of the engine. We did not feel safe at all on the way home. On September 13, 2016, we took our vehicle to butler Toyota where we purchased it for a checkup. After the diagnostic, the service department advised me that the combination meter was out completely. This combination meter must be replaced to restore the reading on the dash board. They told me that this unit is not under warranty, and I must pay $1,698. 42 (tax not included) for this replacement (see attached). This combination meter is a critical safety tool to monitor the driving mechanisms, the condition of vehicle, and when the driver should refill their fuel tank. To resolve the problem, I would appreciate your consideration of this work as a faulty product and should be replaced without cost to the customer. Enclosed is a copy of service from butler Toyota.

Multifunction display functions intermittently. Originally, problem only appeared in conjunction with combination meter failure during cold weather starts. Combination meter has been replaced by Toyota per their extended warranty but multifunction display problem persists. On cold starts in the morning the unit does not function. Later in the day, after sitting in the sun for a while, the unit will occasionally start to work but might go on/off and reset itself while driving. All navigation memory is still there, including ac settings but phone settings are wiped out. This multifunction display is the primary control for ac and heater, navigation system, telephone/bluetooth, audio, diagnostics/maintenance, etc. Toyota has informed me that the unit is defective and needs to be sent to the manufacturer (fujitsu) for repair. This appears to be a well documented problem with this unit on gen 2 Priuses 2004-2009. There should be an extended warranty on this piece of equipment just like the extended warranty on the combination meter.

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.
