1 Wiring problem

Failure Date: 02/27/2020

Both the low beam lights are of a problem with recall which Toyota expired the recall on 10/31/2019. I tried few times last 3 years to get it fixed with Toyota portland but they always said 1) don't have parts will call back once available 2) if you have issue we will fix it otherwise now now. Now that both were off and I had to use high beam, I took to Toyota beaverton, or. They said recall is expired. Why will recall expire if it is safety issue? I called Toyota customer support they said expired and you have pay fo yourself. The cost is not just bulbs but internal wiring kit which starts from $600. I am taking it to Toyota portland today as my student daughter needs the lights to drive. We are both in different states (CA and or).

3 Wiring problem

Failure Date: 05/30/2015

On may 30, 2015, our home burned to the ground. The firefighters are certain the cause of the fire was my 2010 Prius - they know the fire started in the rear of the garage, the only other item in that area was a bicycle. Arson, faulty wiring and accidents were ruled out. Investigations continue, but they have identified an arc between the battery and the relay switch. My homeowners insurance carrier (erie) is trying to decide whether they should expend the additional $1,500 to open the relay switch box to see if they can determine if the arc was the cause of the fire, or a result. From the video footage, it is obvious that the water being poured onto the garage increased the intensity of the fire, which was due to the magnesium battery. Thestarpress. . Read more...

4 Wiring problem

Failure Date: 02/04/2015

I recently replaced one of the low beam headlights, only to discover a few weeks later that both of the low beams had burned out. I've never had two headlights burn out at the same time! tonight I discovered that another of the low beams has burned out. That means that this bulb burned out in less than two months and only about 1000 miles. I am afraid to use my headlights during the daytime for fear that they will burn out and not be available when I need them to see again at night. This must be a wiring/configuration defect! please do something about this!.

5 Wiring problem

Failure Date: 05/01/2014

(40) fleet 2010 Toyota Prius. Consumer writes in regards to vehicles headlights malfunction. The consumer stated he had to routinely replace 7-8 headlamps per week on the fleet of 40 vehicles. The dealer informed the consumer the frequent burnout of the bulbs was likely due to wither security officers not properly caring for the vehicle or the vehicles being used more frequently for personal use. Also, the wiring harness failed on the vehicles. The consumer stated there is currently 1 vehicle in the shop now, and the dealer quoted a price of $8,000. 00 to replace the wiring harness.

6 Wiring problem

Failure Date: 03/25/2014

My 2010 Prius has had an ongoing problem with the main headlamps blowing, becoming inoperative and effectively leaving me with diminished visibility. This has happened approximately every 3 months since March 2014. Either one or both headlamps will blow. This is due to a known problem with this model and is covered under a Toyota/NHTSA service bulletin (tsp-0204-12). In my case, I purchased the car used, from a Toyota dealer with the Toyota certified car warranty, but this failure of the wiring harness is apparently not covered. Judging by the percentage of complaints in the safercar. Gov database for this model, this is a common problem and my experience has been typical. In the most recent incident, it was raining heavily and I ended up driving 150 miles with a blown headlamp, unsafe for me and unsafe for those whom I shared the road with.

7 Wiring problem

Failure Date: 11/28/2010

My windshield wipers stopped working for a short time. I have an idea of what could cause this issue among other problems. I had a problem with a vehicle I once owned that the engine would stop for no reason. The dealer could not find a problem but as a precaution he replaced the small wiring harness. My car never failed again. About 6 months later amc came out with a directive to replace the small wiring harness on all of these cars. The problem was that the two ends of the harness were manufactured by different companies that used different plastic. The plastic in the connectors would react with one another and produce a gas. The gas would coat the contacts and cause them to go open. In my case when I restarted my car the contacts would arc and it would run okay until the contacts got coated again. I think this condition could cause almost every problem Toyota is having. I don't know if this condition is related to any of the problems they are having but it might be worth looking into it.
