  BACK OVER PREVENTION: SENSING SYSTEM: CAMERA · ELECTRICAL SYSTEM:SOFTWARE

  Honda (American Honda Motor Co.) is recalling certain 2018-2020 Odyssey, 2019-2020 Passport, and 2019-2021 Pilot vehicles. Incorrect instrument panel control module software can cause the instrument panel to not display critical information, such as engine oil pressure, speedometer, and gear selector position until the next ignition cycle. Additionally, it can prevent the rearview camera image from displaying. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 101, "Control and Displays" and 111, "Rearview Mirrors."

  Risk: Operating a vehicle without a functioning instrument panel or rearview camera display increases the risk of a crash.

  Remedy: Honda will notify owners, and dealers will reprogram the instrument panel control module software, free of charge. The recall began September 23, 2020. Owners may contact Honda customer service at 1-888-234-2138. Honda's number for this recall is T89.
