Digital dashboard sometimes is completely blank for extended periods so that I can't see my speed, fuel levels, odometer, and other info. When I start up it happens and continues the whole time I am driving. It is causing other problems related to the hydrolic braking sometimes as well when this happens.

The car was at a stop light when all the dashboard lights went out (nightime). When I tried to turn the vehicle off, the car would not shut down. This is a known problem to Toyota especially on high mileage vehicles. The car has 217,000 miles (original owner). Toyota issued t-sb-0172-09 as a "warranty enhancement program" in order to avoid an official recall of the problem. Unfortunately, I missed the deadline by 3 months.

Both headlights (low beam) go out at the same time. No apparent issue with the fuses. Replacement bulbs experience a shorter than expected (approx. 6 weeks) life before burning out again.

Headlights continue to burn out. We have changed one or both headlights at least six times since may 2015. This happens unexpectedly, going down the road at night one or both headlights will burn out. When you change them, will last a couple weeks to months. Very scary when going down a two lane back country road at night. Any help would be greatly appreciated.

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).

While driving, the instrument panel combination meter that displays the vehicle speed and other information went blank. After pulling over car, I tried to turn it off using the power button but it would not turn off. After a few tries, I held down power button for 5 seconds and it finally did go to accessory mode, but did not turn off altogether. It took several presses of the button to finally get the car to shut off. I talked to my local Toyota service center who told me that this is a known issue and Toyota extended the warranty for the combination meter to 9 years (t-sb-0172-09). Unfortunately, I was 4 months past the 9 year mark, so it would cost me $1500 to replace the part. I have since talked to two other people I know who have the same model Prius and they have had the same issue in the past year, one of which was replaced under warranty as he had the problem before the 9 year mark. The other was in the same situation as me as it happened after the 9 year mark. An online search shows that this is becoming a very common issue and happening to many just after the 9 year warranty expires, resulting in a lot of upset owners. I did check my files and see that a warranty enhancement notice was sent to me a couple of years ago that states that this issue has been reported by a limited number of owners and that if it does has happened to my car, I did not need to take action at this time. In hindsight, I should not have followed the instructions and instead took my car in and insisted on a warranty repair. I believe that this is a serious safety issue that should be handled as a recall rather than with a warranty enhancement with a limited warranty period. The car has less than 34000 miles on it.

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 insturment cluster ( speedometer, backup camera, etc) failed one night. A system reset restored things the next day, but now it has started to fail routinely. This is a safety issue y incapacitating the speedometer and the backup comera. Toyota states they have extended the warranty once and will not fix it, even though this car has never had this issue before. The car has 60,000 miles. The car also fails to turn off leaving a major potential for an unavoidable accident.

Headlights short out intermittently. Both headlights have gone out, the left has gone out, the right has gone out. If I turn off the lights and flip them back on, they occassionally both come back on, or one comes back on or neither come back on. This is extremely dangerous at night. It has to be electrical. There's no way it's the bulbs, I've owned the car for a year and have blown through many bulbs already. This is getting expensive besides dangerous. This happens on bumpy roads, smooth roads, turning, going straight. I haven't found a certain thing that makes them turn off. This has been happening for a long time, but I can only choose one date below.

The combo meter on my car went dark this morning. I called Toyota and was told that my warranty expired 2 months ago. This is not safe because there is no indication on what the vehicle is doing. Also this feature causes the car to not shut off.

Steering in my 2009 Prius completed failed and locked up. I literally was unable to steer my car. Luckily, I was on a neighborhoor street about to turn into my driveway and was not driving at high speeds or in a turn lane. I cannot believe that an electronic steering component like this can faili? how is this possible? I want to ensure that this doesn't happen to other Prius drivers and ensure that this isn't a faulty part issue. It is a public safetly issue and that there needs to be some sort of back up steering mechisim to prevent this from happening in the event that there is a "short inside the power steering electronic control unit. I shutter to think what could of happened.

The combination meter on my 2006 Prius has an intermittent electrical short. This results in the dashboard lights going out while the car is moving. This problem with the electrical system on the Prius can result in the brakes on the car failing. In addition the car often continues to stay on after we turn it off. This is also a safety hazard. Toyota has refused our request to replace the defective combination meter, even though this is a widespread problem.

Our daughter drove the vehicle to school. She parked the vehicle and found that the vehicle would not turn off. We took the vehicle to the dealership and was told by the service advisor that the cause of this problem was a part called the combination meter. He advised that the part was recalled and we should have been contacted by Toyota. He provided me with a phone number for the Toyota corporations recall department. I telephoned Toyota and they advised me that I was misinformed by the service advisor and that the part was not recalled, but there was an extended warranty issued on the part in 2012. I asked why the vehicle was not recalled and was told because it wasn't a safet my concern is that this vehicle is unsafe if this part fails. By surfing the internet, I found that there have been many complaints by others regarding the same problem. If my daughter would have driven this vehicle home, parked the vehicle in the garage as she usually does. The vehicle would not have turned off. The vehicle is a hybrid and when the battery power was depleted, the gasoline engine would have kicked on. This could have caused a danger, due to carbon monoxide poisoning to any occupants within the house. Additionally, if the anti lock braking system no longer works when this part fails, the braking distance increases in an emergency braking situation. When this part fails the dash goes completely black, the driver is unaware that the abs braking system is no longer working. The driver is also unable to see the speedometer or any other gauges in the dash. Due to recent deaths, due to carbon monoxide poisoning caused by vehicles not turning off. I feel that Toyota is negligent for not taking my concerns more seriously. Toyota is aware that there is a problem with this part, they issued an extended warranty in 2012.

The navigation and audio screens are mostly unreadable in bright sunlight. In order to attempt to see the screens in these conditions some operators may be distracted from the roadway in order to read the screen information. These distractions may include moving heads away from the wheel area in order to get a better view of the screen or attempting to hold objects above the screen in order to minimize the glare from the sunlight. Complainant has owned previous models of Toyota Prius which did not have this problem.
