Actuated the power switch and the brake peddle numerous times to no avail. I tried to select the gear and the car would move. But dash board display did not light. The lights and turn signals work fine. I drove 15 miles home with on display. I selected the park button and the car parked I went to turn off the power button and the car would not turn off the was in the battery mode. I tried to shut it off by disconnecting the 12 volt battery to no avail. I found a fuse that if I pulled it out the car would shut off.

Again I tried the power and the brake numerous times to no avail. I tried the fuse trick again it worked the engine stopped. Replaced the fuse and tried the power button it work and the dash display were lighted with numerous lights because I shut the down in unapproved mode. Turned the power switch on & off. Numerous times all light were normal except the check engine was on I drove to the Toyota dealer. I was told that is a normal issue the dashboard displays go bad. I understand the dashboard display can go bad. My issue is the safety problem that when the display fails the power button does not shut car off in the battery mode or the engine mode. That¿s a big issue .

2004 Toyota Prius. Consumer states unintended acceleration the consumer stated the sudden acceleration happened three times, over a six year span. He managed to put the vehicle in neutral, coast to the side of the road, and turned the vehicle off. Once the vehicle was restarted, all worked fine. The consumer stated a few weeks ago his vehicle was about to reach 300,000 miles, as he reached for his camera, he realized the odometer never went past 299,999 miles. However, within five miles, the vehicle suddenly lost power brakes, the air condition stopped working, the hybrid drive shut off and the fan for the hybrid battery came on, as well as yellow and red lights appeared on the dash. Also, two warning graphics appeared on the navigation screen, one indicating trouble. The consumer pulled over, and shut the engine off. He then restarted the vehicle and everything went back to normal. It appeared that by shutting off the engine and restarting it, caused the main computer reboot. The consumer stated it continued several more times, until he arrived home. The dealer informed the consumer the vehicle was a large computer, and when one component stops working, such as the odometer, other components cease too. The dealer explained an odometer limit was placed on the vehicle by the factory.
When starting the vehicle up, no speedohmeter display is illuminated. The display for the vehicle enviromental controls (miles per gallon/energy use) still works. Along with the speedohmeter display, the rear hatchback door does not work. I tried to adjust the inside light display to see if the light level was turned off. This was not problem. I turned the light adjustment knob in both directions, and still no speedohmeter display. Upon trying to turn off the engine, it will not turn off. I was able to shut the vehicle off by disconnecting the car battery in the passenger side rear hatch back area. Note that because the rear hatch back door does not work, all the vehicle parts which leads to the rear battery has to be taken out from the rear seat of the vehicle. One particular time I disconnected the car battery on the black portion of the battery,and the vehicle did not shut off. I brought the vehicle to the Toyota dealership several times, and because this problem happens intermittently. Toyota was unable to duplicate it. However, one day when it was not working, I brought it in to them. They later claimed that it was a "cold start" problem to the computer that is responsible for the speedohmeter display (besides other things, rear hatch back door, cruise control, etc. ). Toyota claimed they found the problem on the internet, and it was not a recalled part. This particular part (computer) normally happens only in the states that are very cold.
The multifunctional display (mfd) failed following dealer replacement of the 12v battery. The dealer is now recommended $5,000 replacement of the mfd. Mfd failure in the Prius seems to be an increasing event based on on-line chatter on blogs. This appears to be a basic design flaw in the Prius mfd system that causes loss of communication between the radio and climate control systems. It also causes the display to be totally ineffective for display of key hybrid engine performance.
The contact owns a 2010 Toyota Prius hybrid. The contact stated that while driving 10 mph, the vehicle stalled and a hybrid system failure message came on the instrument panel. The vehicle was taken to the dealer who was unable to come up with a concrete diagnosis but stated that the failure might had been caused by a one volt over charge on the hybrid battery which happen as a result of excessive braking. The manufacturer was made aware of the failure who offered no assistance. The failure mileage was 41,000 and the current mileage was 43,000.

Approximately one week after having my battery replaced by a Toyota dealership in temecula, CA the digital display on my dashboard stopped working and no longer displayed my speed, gas tank gauge, trip mileage or total mileage. After another week or so passed, the display, or cluster display, as it is listed on a Toyota repair estimate from November 3, 2011, would work intermittently by again displaying my speed, gas tank gauge, etc. The display would sometimes work for a few hours and then stop working, and not work again for several days or a week or more. Currently, it the display continues to work intermittently only, causing me to drive for days or a week or more with no visual display of how fast I am driving or how much gas I have remaining in my tank. This failure of the cluster display is a hazard to me and especially to my young teenage daughter because we do not know for sure how fast we are driving or how much gas we have remaining at any given time when the display stops working. I had my vehicle inspected by the Toyota dealership in temecula, CA and they recommended replacing the combo meter since they believe there is an open circuit in the combo meter, but they could not guarantee that their recommendation would resolve the problem. They then advised me that a service bulletin was issued for problems with the cluster display, but no recall has been ordered and they could not cover the cost of fixing the problem under warranty. I then called Toyota corporate offices at 800-331-4331and spoke to the service director, who offered me a 40% discount on the cost of replacing the combo meter on a reimbursement basis and said if a recall was ordered I would get a full refund. I believe the problem on my Toyota Prius of an intermittently functioning cluster display presents a significant hazard for the reasons stated above and warrants a recall.

Note: the date above does not reflect first date of occurance. This is the event date that led to Toyota admitting something is wrong with the car. Please read narrative: on three occasions the car has died while being parked at work and at home. On one occasion the car died in my garage. After the vehicle was jumped it seemed fine. No lights were left on nor were any electrical devices plugged into the accessories. When it started up the car stated that the parking brake was not properly engaged and the vehicle needed to be moved to a level surface. It was in my driveway. Another time the car did the same thing, dying at work in the airport employee parking lot. The car required being jump started and again it gave the same message. A CO-worker stated that they had heard the car alarm go off at one point about an hour prior to shift change. Both times the vehicle was checked and the report was â€œnothing was wrong with the car. Â€� most recently on 3/27/2011 the same thing occurred. This time when jump starting the battery the carâ€™s engine started and the car lunged forward at me with lights and alarm sounding. I was unable to shut down the alarm and went into the car and pressed the power button to shut the engine down. When I powered the engine back up the car alarm was again sounding and all the lights on the dash were illuminated. Powered it down and up again and this time no audible alarm but the exclamation mark in the triangle was illuminated as well as the message about the parking brake. I powered it down and up one last time and, with the message still illuminated, drove off. The message shut down when I got to the security gate. Toyota tested the vehicle on 4/1/2011 and reported that c1300 and c2300 faults were found (ecu and abs actuator). As the car is out of warranty, cost will be about $3,000. 00. (more info exists but no room here).

2007 Prius (69k miles). Driving on highway, all caution lights came on. Towed to dealer and diagnosed with a 12-volt battery issue. $280 to replace the batter. Three weeks later, same cautions lights. Got most to clear with a restart with the exception of the "master caution" and the "engine check" lights. Dealer showed code of "p0a93" and stated inverter coolant pump needed to be replaced for another $486. Check online shows Toyota knows about the pre-2006 issues and that many 2007 and beyond owners are running into the same issue at various miles.
Multi function display (mfd) failure in 2004 Prius. This failure it intermittent and causes the radio to turn off, prevents the use of climate/radio controls located in/on the mfd unit, prevents one from knowing whether the battery is charging. The steering wheel controls seem to work for the climate control (though one cannot see the temperature setting) but the audio system is useless without the mfd unit working properly. This is a $3000 (not including labor) repair . . . And that is for a used refurbished part! totally unacceptable if you ask me. Because this is a known problem impacting thousands of Prius owners, Toyota should be forced to replace these defective units with new units at no cost to the owner.
2007 Toyota Prius with tire failure and brakes grabbing. The battery and headlights failed. The consumer stated Toyota has since removed this particular type of bulb and assembly from production. When the vehicle was 1 year old the consumer was stopped by the police and given a warning for the headlight being out. However, when the consumer and her husband exited the vehicle, they along with the police officer found both headlights were working and he let them go without a citation. The consumer has since discovered that one headlight or the other will just go out on occasion during every drive. The brightness of the headlights began to dim when the vehicle was only a year old. Toyota recommended using the headlights less and they further recommended not using the highly touted feature that allows the lights to automatically turn off after the vehicle has been turned off. Last month, the consumer received a letter from Toyota regarding information about a problem with the hid headlights. The letter stated the customer support program would reimburse for some cost relative to the defective headlights. However the local dealer did not agree and the cost far exceeded anything mentioned in the letter. The dealer informed the consumer the cost of installation for new bulbs would be $245 in labor for each headlight replacement, that was in addition to the exorbitant cost of the bulbs themselves.
I own a 2010 Prius. I have owned the car since oct 2009. Twice I let the car sit in my garage without driving it for 6 days. The battery completely discharge over the 6 days such that the car has to be jumped in order for it to start. Both times I took the car to Toyota service center and both times they did not find anything wrong with the car. There solution was to not let the car sit undriven for that long. However, if I took the car to the airport and left it while I was gone for a week, it would not start when I return. This is not acceptable to me since I travel a lot. According to Toyota I have no recourse.
Toyota Prius yr/mdl 2009/1224 a
I have attempted to have the following checked with Toyota of hickory where I purchased the Prius and was told that I needed to allow the battery to heat up before trying to place it into reverse or drive. My Prius will go into n, it will lock all doors and windows and not go into gear or start. I have been locked in the car during this past summer without air and I attempted several times to cut the car on and off before it would go into gear. This is very horrific to say the least. I was at lake norman Toyota yesterday and was told this was a common complaint. Yet no one offered to take this car in and check for problems. From the day I drove off the lot until now this hybrid gas/elec sedan has given me nothing but trouble.

I own a 2004 Toyota Prius. Just last week the touch screen that controls the heating / air conditioning, the radio, the current mpg information and condition of the ni-metal hydride battery and the gas engine interconnections, began to fail. Sometimes it works for a while, then it stops for some time then it might or might start working again before I get where I am going. It is extremely intermittent in its correct operation. I have read on the internet that many other 2004 and early 2005 Prius owners have encountered this problem, but that Toyota is refusing to issue a recall. The new part is very expensive (~$4,000). Refurbished parts are not readily available for the Prius, I suppose because it is a relative new model to Toyota. I wanted to report this to you, in the hopes that you might have some way of letting Toyotal know that one more owner is having this problem. I did not know if you can force a manufacturer to issue a recall when a certain number of owners complain, or if this is only the case where safety is involved. Regards, dale w. Howard.
I was on a trip to arizona and when driving in my 2010 Prius from flagstaff to phoenix during the evening, the batter display's top segment glowed red many times in the descent from flagstaff. It was a very difficult to drive to keep the top segment from turning red as the vehicle was coasting and I did not want to exceed the speed limit so I really did not now what to do. I decided to shift to neutral so the engine was not breaking. However in neutral I was wearing out my vehicles brakes which also worried me because of the possibility of overheating the brakes. I looked in my vehicle manual but nothing as in the booklet about this type of occurrence. So I asked my Toyota service personnel at rudy luther Toyota in golden valley, mn and they had not heard of this problem. He gave me a the telephone number for customer service representatives at Toyota and after discussing this incident with many people in customer service at Toyota, the end result was "that the battery was fully charged and when this occurs the top bar will glow red but this will not effect the battery". I do not know if this is true or Toyota is just putting me off but others at the following Toyota forum have also experienced this problem. Is this a safety problem, I do not know. Is it a battery warranty problem, I do not know. But please look at this forum thread and maybe you can discuss this more fully with Toyota. . Read more...

On 2/27/09, my 2005 Toyota Prius' brakes completely failed. I was going downhill in an highly transited urban road (rte 123 in va, close to tysons corner). Thankfully I was only going about 40mph when the light changed to red. The 2 vehicles in front of me stopped. I pressed the brake pedal and my car accelerated initially, and then nothing. Brakes are meant to work. Always. I kept pumping the pedal hoping to engage the breaks, but they did not engage. What stopped me was the rear of a BMW x5. Thankfully I was the only injured party, and my injuries are mostly muscular. I could have died or I could have killed someone. In January, I had taking my car to the dealer because all the alert lights on the dash would sporadically go off. They kept the car for a week and claimed that the secondary battery needed to be replaced. I got my vehicle back and on 2/23/09 the issue restarted. I was due to take my car back to the dealer the day of the accident. I called a lawyer to see if I had a case, and was told no. I am still researching the issue because someone should be held accountable and future tragedies should be avoided. If anyone has started a class action suit, please do let me know as I would like to join you.
