Wiring problems of the 2005 Toyota Prius

Passenger headlight goes off intermittently. Turn switch off and on and comes on again. Have had bulb replaced x2 and now Toyota dealer says that Toyota has a bulletin about it. Note to the tune of $500 to fix. In researching this seems to be a common problem. It's a hazard at night or in rain or inclement weather and evidently something Toyota has had complaints about enough to put out a bulletin. Vehicle in motion, highway miles. I believe some sort of short but certainly not mechanic. This has been happening since January 2017. Two new bulbs plus labor and now told wiring mechanism. Help. If Toyota knows a problem, address it in a recall.

The contact owns a 2005 Toyota Prius. While driving at approximately 25 mph, the air bag warning light illuminated on and off. The vehicle was taken to an independent mechanic. The technician diagnosed that the main wiring harness needed to be replaced and not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 65,000.

On 2/27/14 the srs indicator light in our vehicle lit up causing us to review the owner's manual, which recommended immediate service. Per technical service bulletin t-sb-0042-11, this issue was caused by failure of the wiring harness, which was diagnosed with scanner code b1826. According to the TSB, the design/material fault can occur in 2004-2009 Priuses. The fault, according to a Toyota service advisor, results in a failure of the air bag system. To address the condition, "an updated wire harness must be installed. " the cost to repair this design fault is $2,500. And up depending on if one or both sides of the wiring harness has to be replaced. Because this safety related defect needed to be addressed at once we paid to have the vehicle repaired but expressed our view to the Toyota personnel that the defect should have been covered by Toyota. We feel that this defect should have been the subject of a recall. Calls to the gm of the dealership have not been returned.

Our 2005 Prius shut down on 07/15/06 while my wife was trying to get home that evening. She was 200 miles from the nearest Toyota dealer. The car needed to be towed from alamosa to pueblo. A complete car shutdown is a very serious safety hazard especially if you are a woman in a desolate road at night. The car has less than 35,000 miles. Toyota failed to completely reimburse all my cost. My wife had to stay in a motel that night and I incurred the cost of getting her home and then driving from denver again to retrieve the car. Along with the safety issue and toyatas' refusal to reimburse all my costs, has left me totally appalled with Toyota. The mass airflow sensor I am being told is the cause of the vehicle shut down.

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.

Appears to be a temporary engine stall at 68 miles per hour in carpool lane, warning light came on but disappeared right away and the car was fine again. But lots of car vibrations and jolting felt at the time.

New vehicle had master fault, check engine and other warning lights at odo reading 50, "repaired" faulted again. Replacement parts include cam sensors, computer boards, wiring harness and now "master computer board".
