  BACK OVER PREVENTION:DISPLAY FUNCTION

  Honda (American Honda Motor Co.) is recalling certain 2018-2023 Odyssey, 2019-2022 Pilot, and 2019-2023 Passport vehicles. Due to a faulty Media Oriented Systems Transport (MOST) communication coaxial cable connector, the rearview camera image may not appear on the display. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."

  Risk: A rearview camera that does not display an image can reduce the driver's rear view, increasing the risk of a crash or injury.

  Remedy: Dealers will replace the MOST cable harness and install a straightening cover over the vehicle cable connector, free of charge. Owner notification letters were mailed July 24, 2023. Owners may contact Honda customer service at 1-888-234-2138. Honda's numbers for this recall are EEL, ZEM, and SFC.

   My 2021 Honda Passport experiences a sudden, complete failure of the digital instrument cluster and infotainment screen while driving. The dashboard controls go pitch black without warning, resulting in an immediate and dangerous loss of the speedometer, critical vehicle safety warnings, and the federally mandated rearview backup camera. The system stays dark for 3 to 4 minutes before attempting a forced system reboot. This matches the exact failure mode of NHTSA Recall…

   This has happened several times but today it was dangerous. I was doing around 40mph and there were some changes in the concrete color and my car slammed on the breaks (again) for no reason. I was almost hit. This keeps happening in my vehicle and I am terrified to drive it. Please help get this recalled. I have a child with cancer and I bought this safer vehicle to transport her to the hospital.

   Driving to work in normal speeds and conditions. The emergency braking enabled and slammed on the brakes to my car - despite there being no threat or need. The brake was with such force that I jerked forward. This is the third time this has happened with this car in the past week. Car is available for inspection if needed. The car has not yet been inspected by Honda for this situation.

   I bought my car in 2021. Two weeks ago 4-5 dashboard signs came up on my screen. I contacted local dealer and they said they need nearly $3000 to fix it. I told them it’s a safety issue and they refused to budge. I complained to Honda through X and they refused to help me. They are not taking it seriously

    I purchased a used 2021 Passport the end of May 2025. While driving, the 'collision mitigation braking system' or CMBS would activate the braking system and would intermittently just brake, causing panic for not only myself, but I'm sure drivers behind me for suddenly braking with no imminent threat in from of me. This happened multiple times without receiving any warning or notifications, just suddenly. It would happen without warning, or sometimes nearing a bridge or a…

    One day the lights just started flashing. Took to dealer and was told that someone must have backed into me and would be about $2500 to replace the camera (which is behind the windshield). Occasionally it will function but clearly seems to be a malfunction. In research online there appear to be many others that have experienced the same issue - can’t just be a coincidence. Shouldn’t happen on a reliable four/five year old car
