2005 Toyota Prius right hid headlamp flickers and sometimes turns off while driving. Dealer will not cover extensive repair cost. From internet information this seems to be a very common problem that could be very dangerous if both headlights quit simultaneously.

The contact owns a 2005 Toyota Prius. While being serviced at the dealer, they noticed that the headlights were distorted. The plating on the internal part of the headlights were overheating. There is no way to release this heat and the contact is concerned that a possible fire may occur. The vehicle was taken to the dealer, but they did not want to be responsible because it was no longer under warranty. The failure mileage was 40,000 and current mileage was 41,000. Updated 01-14-08.

My 2005 Prius had engine failure while traveling at high speed on the highway. I pulled over and had to get the car towed, and the computer reset. I soon after learned of a recall, and now I am told that my car does not qualify for the recall. I think it is unsafe, and I want the computer problem remedied.

While driving on the freeway at speeds up to 65 mph pulled off and went through a small town. After coming to a stop light started to press the gas pedal to accelerate and the red triangle with an exclamation mark lit up on the dashboard, and then the small car with exclamation mark came on the lcd screen. The car didn't stall nor loose power, but I pulled over to check and see what the owner's manual said. It stated to contact the dealer. Had the car towed. Tried to power off and on twice but the icons still remained, and on the lcd stated a problem existed. Also, it seemed T when I powering on/off the engine did not kick in as usual. However, I am not sure, if I left the car powered on long enough because it usually took 20-30 seconds before engine kicked in.

I have a 2005 Toyota Prius. I got my car 8-23-2005 and on 10-13-2005 I was hit on the passenger side while making a left hand turn. The intersections was just after a traffic circle, signs was missing, it was raining, dusk and the person who hit me did not have her lights on and was driving too fast for conditions. My car stopped, and could not be restarted. It was towed. I called my insurance company and was sent to a repair facility. After several days they got my car, but because it would not start, towed it to a Toyota shop. It sat there for 10 days, until I called, then it was sent back to the repair shop. It took 6 more weeks for the car to be repaired. One delay was in getting the seat-belt, which was supposed to come with the seat, but did not. It had to be shipped from Japan (I was told). After the repair was done, 9 weeks after the accident, the car would not start. It was towed to another Toyota dealership. Two weeks later, I am told that a wiring harness was the problem. This has to be shipped from Japan, and the expected date of arrival is 1-11-2006. Meanwhile, I have not had my car for nearly 3 months. My insurance paid for 30 days of a rental car (I waited a week to get the rental car), then I paid for another 4 weeks. I have notified Toyota 2 times about this situation. I have called the dealership, where I have a "special" customer convenience card. This card only seems to be good for purchases, and not for actual assistance. I think Prius owners need to know that their cars can only be repaired at a few locations, and most dealerships can not repair them properly. Additionally, I think the car has a significant blinds pot, as I am frequently surprised by other cars suddenly appearing.

2004 Toyota Prius with 23915 miles on it. Driving to work West on I-90 during rush hour engine stopped dead. I-90 is 8 lanes of traffic in spokane, wa. Had to have car towed to dealer for repairs. Problem was a failure in the electronic control unit. ECU had to be re-programed. Cause found by dealer: Found code P3191 & poaof codes. Found tbs #EG047-04. According to the service advisor, Toyota issued a technical bulletin covering this problem but stated there were too few failures to warant a recall. Being on an interstate during rush hour with traffic doing 70+ mph and having an engine failure could create a life threating situation very quickly. The last thing I asked the service advisor is if this will happen again? his response, "it shouldn't." that's reassuring.

Prius 4-cyl

The Prius shut down, stopped using gasoline power, while I was in the passing lane and traveling 70 miles per hour in moderate traffic on interstate 40 in nashville, tn. The red triangle, check engine, vsc and a few other warning signals illuminated. I managed to avoid being rear-ended, pulled to the side of the road using battery power, shut the battery power off, and consulted the owner's manual. Approximately 10-15 minutes prior, the add fuel light illuminated and the fuel indicator displayed a single bar. Having driven the vehicle for the past 8300 miles, my wife informed me that we had about 2 gallons of gas, and could easily travel another fifty miles. The temperature was near 90 degrees. I started the vehicle and chose to drive it off the interstate. We traveled 2.5 miles and coasted to the side of the road as the battery depleted. I managed to slowly drive the vehicle to a gas station and refueled. The fuel tank could only accommodate 8.1 gallons of fuel; it holds 11.7. once refueled, the warning signals disappeared after 30 seconds, and we drove home. My wife took the car to the dealer, joe heitz Toyota in clarksville, tn, the next day for an evaluation. The mechanic said that the computer indicated that the vehicle ran out of fuel. Since there obviously was fuel in the tank, I pressed the service manager for answers. By the end of the day and after consulting with Prius technical folks in California, the service manager said that the fuel bladder may have collapsed over the sending module thereby signaling the car's computer that it was out of gas, which caused it to shut down. He said Toyota is looking into the problem and provided a lame solution; refuel the vehicle before it gets too low. This is an unacceptable answer and I implore the NHTSA to investigate this potentially deadly anomaly. It is only a matter of time before someone is in a fatal accident because the vehicle shuts down while traveling at interstate speeds.
