Three problems related to horn assembly have been reported for the 2013 Toyota Prius. The most recently reported issues are listed below.
My Toyota Prius was involved in a hit run accident. Yark collision completed work on vehicle. When picking up car from yark my car would not start spoke with one of the mechanic he said my battery died and I explained to them I had no issues ,prior to bringing my car to yark I had just had diagnostic test done at Toyota. Vehicle sat at my residence over night and vehicle had died again. I contacted yark told them I was bringing battery in for them to charge because I was not sure as to what was going on since we had already replaced battery. Vehicle also had my skid plate in trunk prior to drop off and now I am having electrical issues my horn now does not work and I have children . I did not receive my car until 1 month and half due to insurance not getting back to us . Vehicle has been non drivable since pick up.
Often referred clock spring as it is referred to part number 84307-47020 it affects a multitude of things on my car that are safety related including the horn, the buttons on the steering wheel that control the radio and tricks odometer, the airbag, maybe be airbags plearle, be adaptive cruise control and maybe other things. My knowledge my car has never been wrecked or had airbags blown and this is very premature for this part to fail. Believe Toyota should take responsibility for it. The warning light came on and it says in the manual that is unsafe to drive. Do not have a clue why it failed. The Toyota dealer repair is close to $900 which is ridiculous.
Toyota Prius emits a loud and distracting beeping tone inside the cabin when placed in reverse. The tone is so loud that a driver may not hear shouts, a horn, or other exterior noise indicating a hazard while reversing. Toyota dealerships charge hundreds of dollars to turn off the interior beeping, despite the evident safety hazard is poses.
