Chronology :

  • March 2020: KawasakieBay logo Heavy Industries, Ltd (KHI) received a report from a Japanese distributor (KMJ) that the horn harness was broken and the horn was not working. KHI Quality Assurance Division started investigating.
  • June 2020: KHI found that the horn harness was broken by fatigue failure, not impact fracture. KHI tried to duplicate the failure, but could not.
  • June 2020 – December 2020: KHI continued to monitor the field and took note of 6 incidents of horn malfunction in the Japanese market. No incidents were noted in the US market.
  • January 2021: KHI tried to determine what frequency of vibration was occurring during operation of the vehicle, and whether that frequency of vibration was high compared to other models, thus weakening the harness more quickly than other models of vehicles. KHI did not find that the frequency of vibration was higher than in other models, and therefore could not determine why or how the harness was failing prematurely.
  • March 2021 – July 2021: KHI continued to monitor the field and took note of 9 incidents of horn malfunction in the Japanese market. No incidents were noted in the US market.
  • July 2021: By modulating both the frequency and amplitude of the engine vibration, KHI was able to replicate the premature failure of the harness, but the failure conditions were thought to be very rare in the field.
  • December 2021: Regardless of the rarity of the observed failure conditions in the field, in an abundance of caution KHI developed a rubber damper to reduce the vibration which was weakening the horn harness.
  • February 25, 2022:KHI decided to initiate a recall campaign to address this issue.
