Around or just after 40,000 miles the right headlight on my 2008 Toyota Prius started turning off while driving. Turning the lights off then on corrects the problem -- but this is annoying and dangerous when driving at night.

After driving for about 500 miles the car was parked in the garage for two days. When I tried to start the car the 12V battery was dead. I used 3 different batteries to try to start the car. The lights came on on the dash but there was a warning message that there was a problem with the transmission and needed to put the car on a level surface which it already was, and the transmission would not come out of park and the motor would not start. The car could not be moved. When a new battery was installed the car resumed working fine. If the dead battery had happened when we were stopped on I81 because of construction, we would have been stuck in the fast lane with no way to move the car out of the travel lane until a tow truck arrived.

I was driving my 2008 Prius about 20 to 30 mph down a straight road, a slight descending grade and coasting, when it accelerated with my foot off the accelerator pedal. This happened for about 4-5 seconds and a speed gain of approximately 5-10 mph. It startled me, if a car had been in front of me, there would have been a serious problem. A light flashed on the dash but it happened so fast that I could not tell which light. I called Toyota of longview and was told if it was not acting up they could not do anything about it. We had bad weather so I parked the car until we could carry it in. Feb 9th, 2011, we had the dealer check it and they found nothing wrong. I would sell it but it what if someone else got in an accident? something needs to be done.

On 3 separate days, 2 during the summer of 2009 and 1 during the summer of 2010, our Prius transmission has automatically and repeatedly shifted from D (drive) to N (neutral) without warning while the car was moving. All incidents happened on extremely hot days (temperatures near 100) in the afternoon after the car had been parked out in the sun and without us having made any accidental contact with the shifter / drive selector while driving. This created dangerous situations several times as the car erratically slowed as we entered intersections or pulled out onto busy streets. Our initial response was to depress the accelerator, but when this had no effect, we discovered the transmission light had moved from D to N. it was especially dangerous when making left hand turns on busy streets with oncoming traffic. We discovered that we could keep the car moving by constantly holding the shifter / drive selector lever in the D position. Turning off the air conditioner did not help the problem. After the first time this happened, we took the car to the dealership to investigate the problem, but the service technicians there were unable to reproduce it. This glitch remains a concern to us because the loss of power and acceleration is unpredictable and therefore dangerous, but at least we know we can keep the car moving by holding the shifter in the D position. Because the car is so computerized, I suspect an electronic component of the drive system may malfunction at high temperatures. The mileage number I gave is an approximation since I didn't record the actual mileage when this first happened, but the dealer who serviced the car shortly thereafter should have that information.

Headlight goes on, then goes off. Won't stay on. I was informed the other one could go out at any time, so I should replace both, at great expense. I was told by Toyota that the hid headlights were covered under the regular warranty, but not the extended warranty. Bulbs (especailly those costing $300) should not burn out or randomly flicker on a two year old vehicle. To prevent future/additional problems, I had to replace both headlights, including the one that was working. This is a definitlely safety issue...I check bulbs regularly, and all are working when I turn the car on. Obviously, I can't check while I'm in motion - which is when they flash off - and was fortunate that both bulbs didn't burn out at the same time, which could have resulted in a crash, injury or accident (or worse) that I would have been liable for.

The instrument panel on a 2008 Prius decides not work at varied times. It is a sporadic problem which occurs then goes away. You could be driving down the highway at night then you see that you have no display telling you: 1) how fast you are going, 2) how much gas do you have, or 3) distance traveled. It's too difficult to troubleshoot because the problem would goes away.

Prius starts when the power button is pushed. There is no dashboard lights and since the dash board is digital there is no way to tell what gear the car is in or what speed you are traveling. Car drives without an operational dashboard which the dealer does not recommend. Car is under 2000 mile warranty. Dealer unwilling to repair combination meter which is the cause of the problem because they could not replicate the problem while at the dealership. Problem is well documented on Prius chat. Cost $1600.

Hid headlights unexpectedly shut off while driving. When I turn them off, then back on, they work perfectly fine, but I don't know when they'll go out again. This is clearly a safety issue. It does appear that the hid headlight equipped Prius has some electrical or design defect.

Hid headlights that unexpectedly shut off while driving, but come back on when manually turned off, then on. Appears to be problem with the electrical system, not the lights, or a design defect.

- Huntingtown, MD, USA

Hid headlights unexpectedly shut off while driving. This is clearly a safety issue and appears to be a defect with the electrical system or design of the lighting components other than the bulbs because if I turn them off they come back on fine every time like there's nothing wrong with them.

Severe safety concerns with a 2008 Prius are the following: The answers and solutions to the following are necessary before anyone could be considered safe driving this 2008 Prius: 1.why did our Prius have a power failure on April 13th while driving at 60 mph on a flat stretch of hwy 101 going North at the blithedale exit in mill valley, ca" 2.why while driving up divisidero around 11:30 or 12 noon on April 25, 2010 did the car begin beeping loudly when going up the hill in pacific heights? 3. why did it then start making two different beeping sounds? we then pulled over and found that the transmission indicated that it had jumped into reverse even though the car was still going forward. We had not touched the shift lever, both hands were on the wheel. It jumped into reverse by itself. 4.why, after we then returned the shift to drive, were we able to go further up the hill and the loud beeping started again while the transmission was still in drive" we stopped the car and kept a foot on the brake pedal until help arrived. Aaa came. Aaa drove the car without beeping to a more level part of the street to load it upon a truck and carried the car to the san francisco geary Toyota service center. They have yet [5.20.10] to accurately diagnose and correct these problems so it is safe to drive.

The 2008 Toyota Prius has a strong smell that resembles a electrical burning smell it makes your eyes water and your cloths smell like it long after you have left the vehicle. The dealer is not sure where it is coming from. There are other reported claims of the same smell on the internet.

Hello....I just received a notice from Toyota entitled customer support program..(no mention of recall). In it, they say that there is a problem with headlights going out...and while they've been charging for them at 300 dollars each, they now realize that it's some kind of electrical issue....that causes the lights to fail...now, in light of everything else, it seems that this is a potentially serious problem and should be a recall...not a "hide the problem" kind of customer support letter......someone should be monitoring this one too....if Toyota can hide something that is a recall-warranted problem, what next..? it worries me....

I left my 2008 Toyota Prius running and had to run back into a home where I'd just left a sales appointment. Eventhough I had the key fob in my pocket, I noticed out of the corner of my eye as I was crossing the street back towards the house that my car was careening into the Buick parked across the street. I ran and jumped in and steered it away from T-boning the parked Buick, but could not keep it the driver's side of the Prius from scraping along the driver's side corner of the Buick's rear bumper.

2008 pruis- twice in cold weather the computer dashboard indicators wouldnt show any info including speed of car and the car would not turn off. I called the dealership and they said they had never heard of this before. After about 30 minutes of driving around the dashboard came on and I was able to turn the car off. I looked this up online and others have had this problem in cold weather with the pruis.

Our office owns a Toyota Prius that I drive occasional to work assignments. I took the car on a trip to see a work project but stopped to pick up another employee before heading to the site. When I pulled up to pick up the employee the Prius's entire dashboard display went blank. I pulled the car into a parking space and tried to turn it off. The "key" would not come out of the receiver. I realized the car was still running so I tried repeatedly to turn it off by pressing on the power button. The other employee showed up so we drove the car back to my office (2 blocks) got another vehicle and I drove the Prius to the office service garage. The garage staff couldn't turn off the car either. So I left it there. Later the garage called to say the car was ready. I asked them what was wrong with the car. They say it just had to be re-booted by holding down the power button for 10 seconds. After hearing about people getting killed driving Toyota products and Toyota saying there is nothing wrong with the vehicle computer I thought I should write and tell you it is the computer! if you are interested in hearing more details or picking up the vehicle for inspection you can E-mail me. I can fill in a lot of details when I get back to the office. I used 1/12/2010 to get through this form but I can check the date when I get into the office.

I purchased a 2008 Prius with hid bulbs and they both started going out a couple weeks after owning it while I was driving home at night. In just a matter of minutes, I had no lights at all! I was in a urban area, so the street lights were there so that I could see. But if I were in the country, as I usually am about once a week, I would have been in big trouble.
