Two problems related to horn assembly have been reported for the 2010 Toyota Prius. The most recently reported issues are listed below.
The spiral cable assembly in the steering wheel has created a short circuit and now the horn no longer works. I am concerned this is a similar problem as other 2010 Toyotas experienced and had this same part recalled in 2014 to ensure the airbag would go off appropriately if needed.
Tl the contact owns a 2010 Toyota Prius. Each time the vehicle was driven, it shook, stalled, and the check engine warning indicator illuminated. In addition, the contact had to depress the brake pedal with excessive pressure for the brake lights to illuminate. Also, the horn failed to function. The vehicle was taken to south bay Toyota (located at 18416 s western Ave, gardena, CA 90248, (310) 323-7800), but was not diagnosed or repaired. The vehicle was later taken to autonation Toyota cerritos (located at 18700 studebaker rd, cerritos, CA 90703, (562) 802-4000), but was not diagnosed or repaired due to the repair fees. The VIN was included in NHTSA campaign number: 18v684000 (hybrid propulsion system). The manufacturer was not notified of the failure. The approximate failure mileage was 100,000.
