Failure Date: 08/24/2015

One of the headlights worked sporadically. It happened the same day I purchased the car used from a Toyota dealership, but I didn't notice it right away because it was daytime. The next day I went to the service department and they said I needed to replace the hid bulb which costs $300!!!!! after complaining to the dealership they replaced it at no charge, but I am concerned that this might be a recurring problem. I don't know if they replaced any associated parts or not, since the invoice they gave me just listed "engine elecrical concern" without an itemized list.

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 was driving my husband to work when I noticed the instrument panel was completely dark. Tried turning the car off and then on again with no effect -- panel was still dark. It's particularly worrisome that I had no speedometer to tell how fast I was going, nor would any of the other indicator lights come on. When I tried to turn the car off a second time, it wouldn't power down, and I couldn't extract the key. I couldn't even lock the car so I could leave it there to seek aid. In doing research, I found that this is a known fault with the combination meter and Toyota knows this is a problem and issued a warranty extension. However, their warranty only covered cars currently experiencing the problem when the letter went out and during a specified date range, irregardless of mileage. They would not have replaced the part during the warranty extension because I had not yet experienced the problem, and now they refuse to replace the defective part because my experience happened 4 months after their arbitrary cut-off date. A faulty part is a faulty part and should be replaced when they know it's a problem. This is a serious safety issue that should not have a time limit. The car is not safe to drive if you don't know how fast you are driving, how much gas you have, etc. And you can't shut it down or lock it either.

Failure Date: 07/09/2015

Speedometer & other control information display went blank. Pulled over to side of road but unable to turn off engine. Contacted Toyota & was told problem is known & warranty extend to 9 years & unlimited miles. However, my vehicle is older than nine years, so I must pay estimate $1400 to fix & car will be unavailable for estimate 2 weeks. The vehicle is unsafe to drive, prior to this known problem occurring car was operating perfectly ( averaging 50 mpg per tank of gas, documented). This appears to be a safety problem that was known by the manufacturer, however they seems to be trying to hide this by making the statistical estimate that by extending the warranty the majority of these cars would be off the road and their lawyers & legal insurance would cost less than the few humans kills after this arbitrary 9 year risk period. I could have been killed as a result of this failure! fortunately I was not, however I am left with a vehicle that is undriveable (with no warning!) and can only be repaired by Toyota at a cost I am not able to afford!.

I am currently experiencing troubles with my front passenger headlight. The problem first occurred about a year ago (Jan. 2014) when I purchased the car used from a car dealer in tysons corner va. I took the car back within days of noticing the light kept going out and asked them to repair the issue since I had just purchased the car. They did so and said that it was most likely a faulty light and replaced it. It is a little over a year now and the same light is going out again. What is happening is that when I turn the car on and turn on all of the car lights to drive it at night, they turn on, but about 15-20 minutes down the road and unbeknownst to me, the right passenger light goes out. Because of the shape of the car, you cannot tell that it is out. The only reason I knew it was out again was because I got pulled over and given a ticket. This is extremely unsafe and I have read a number of similar occurrences online. I took the car to the repair shop and they have said (after looking online) that the issue is the "headlight light control ecu sub-assembly". Because of the safety risk this posses to the driver and others on the road, not to mention the cost of the single item to repair it, Toyota should make appropriate financial accommodations to those having this trouble. Normal ware and tare on the vehicle is reasonable, such as burt out lightbulbs but systems like this that work for a couple days and then suddenly do not is not safe.

Failure Date: 04/19/2015

Bought one-owner 2005 Prius 11-26-2014 after paying for a pre-purchase inspection at a Toyota dealer showing complete service record including all recall campaigns. 4-19-2015 without warning on the expressway, the entire 'combination meter display' simply turned off, leaving the car running in the blind, no gauges/meters/guidance of any kind. The car continued to operate and I drove directly home and parked it. Internet search revealed that this as a known safety issue by Toyota affecting 2004-2009 Prius models. Toyota issued a 'warranty enhancement-ztv' and warranty policy bulletin (bulletin no. Pol12-05) to effect the necessary safety repairs, but only applies if one discovers (meaning suffer the panic of having the entire panel go blank) the issue before either '9 years with no mileage limitation or before September 30, 2013', whichever is longer. In our case, it expired just before our pre-purchase inspection/purchase of the Prius and the dealer indicated/Toyota confirmed that this is not something that a Toyota dealer service department could have discovered through Toyota records. Instead, the owner has to wait for the failure to occur. In our case, Toyota corporate, with full knowledge of this safety defect, said our joint 'plan of action' was (a) if the display does not illuminate, under no circumstances drive the car, and have it towed to the Toyota dealership for necessary repairs, or (b) if the display illuminates, immediately drive it to the Toyota dealership for necessary repairs, but that (c) Toyota would 'decline to further participate or contribute' to the repair. This should be a mandated, required safety recall; by its own measure, up to 669,000 Prius models may be at risk to this known defect, yet Toyota refuses both the recall and the repair. How many out there are ticking time bombs?.

The left headlight keeps turning itself off when driving or not. When bumped next to the headlight cover it comes back on. The bulb and connector are fine. This is a safety hazard, that if the right one starts doing the same thin at night, it would put me into a dangerous and life threatening situation. I think Toyota should have a recall on this problem.

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.

Combination meter failed leaving the vehicle without instrument cluster information. There is a manufacturer warranty extension which does not cover vehicles on the road over 9 years. This represents a hazard to the public which has a documented solution and replacement components.

The dash display mph and mileage totally went black. Looked it up on the internet and seems like it is a common problem for the 2010 Toyota Prius. Sounds like Toyota use to cover this before this year model, but not now, even though it is still happening. They may have done their dash alittle different, but it is still having the same problem.

Driving after dark, temp 12 f, dashboard light went black on area behind steering wheel. Upon arriving at destination, vehicle took several attempts before it turned off. Car was taken to Toyota dealer. I suggested this problem may be on a recall for the multi system light in the dash. After 2 hours Toyota did not address the "recall" issue and diagnosed loose batter cable. Car performed normally. Next morning the car started and dashboard lighting came on as per usual. End of day when temp dropped dashboard went black again and the car was difficult to turn off at end destination. Toyota dealer was called immediately (Sunday) left message. Called again next morning after 10am no call received from dealership.

Our car was exhibiting a serious defect that Toyota has already found and documented on their site, saying that they are doing an extended warranty to correct the problem. However, they have grossly mismanaged this extended warranty by not providing the part at all or perhaps at some far future time (we still don't know when we will get our car back, perhaps months or never). When word gets out that customers who bring their car in to get fixed have no idea when they get their car back, they will instead keep driving the car with the highly dangerous defect. The defect is the combination meter, which controls the dashboard indicators. When it goes down, none of the dashboard indicators work and the driver does not know what gear he or she is in, how much gasoline is in the tank, what speed the car is going, etc. These are the cars that Toyota is leaving on the road because they are yet again incompetently managing a safety defect. This could lead to serious injuries and deaths. I spoke to lisa at Toyota today (January 5, 2015), and, based on the conversation, Toyota could care less whether this is handled right or not. She did not seem the least bit alarmed, and indicated that their course of action was to do nothing. The dealer ordered the part last Monday, but, according to the dealer, Toyota's tracking of this part is completely disorganized. Toyota has no idea when it went out and is ignoring the tracking information provided by the shipper (apparently ups) so the customers have no idea when they get their cars back. Customers are not given loaner cars. If they turn their cars in to be fixed, they cannot go to work. Therefore, they will drive with the dangerous defect. Also, car owners are not being notified of the defect. They only find out the hard way, perhaps right before an accident.

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.
