FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
When attempting to accelerate after completing a stop, there was no response from the vehicle when the accelerator was pressed for 2-3 seconds, then the vehicle suddenly lurched violently forward and hit the rear end of a vehicle in front causing severe damage to the cars.

FORWARD COLLISION AVOIDANCE: WARNINGS
This vehicle is actively immobilized on private residential property with its central ADAS safety networks and Advanced Driver-Assist networks completely crashed and offline (DTC U3000-49) and active short-to-ground circuit failures (DTC B2035) rendering the passenger sliding doors completely inoperable, creating an immediate entrapment and safety hazard. These progressive component failures cascade directly from severe environmental moisture intrusion inside the rear tailgate enclosure. This exact water migration vector intersects directly with active federal safety campaign NHTSA Recall 26-V-423 (Rearview Camera Failure), which isolates moisture intrusion into the panel housing as the root factory manufacturing defect. A manufacturer franchise location documented active water leakage onto the Power Tailgate Control Unit and heavy corrosion on the wiring connector under a previous Repair Order but performed zero interim moisture sealing, corrosion cleanup, or terminal mitigation, allowing progressive water migration to completely destroy the wiring system harness. Furthermore, American Honda Corporate Case Management explicitly stated on a recorded verbal line that the manufacturer is denying all repair assistance to remedy these cascading safety campaign electrical defects under an active corporate case. The manufacturer is in open default of its statutory federal obligation to remedy a safety recall defect free of charge to the consumer.

BACK OVER PREVENTION
The contact owns a 2018 Honda Odyssey. The contact stated that while driving 25 MPH, the audio of the vehicle unexpectedly became inoperable. The failure was a recurring failure. Additionally, there was an abnormal burning odor inside the vehicle. The contact associated the failure with NHTSA Campaign Number: 23V431000 (Back Over Prevention); however, the VIN was not included in the recall. The dealer was contacted and stated that the cost of the repair was not covered because the VIN was not included in the recall. The failure mileage was approximately 90,332.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
I randomly received a series of 6 warning messages when starting the car on 9/3/26. They were all warnings related to the automatic safety features such as lane departure, collision detection, auto bright lights, etc.I took it to the dealer on 9/4/26 & they diagnosed an internal failure with a multi-purpose camera embedded in the rearview mirror. The dealer ordered a new part, installed and reprogrammed and recalibrated the camera. This vehicle has been owned only by me, is kept in a garage away from weather exposure, there is no reason for this part to fail on a 6 year old car with a hefty cost to the consumer.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
In January 2026, my 2019 Honda Odyssey (approximately 110,000 miles) suddenly began displaying multiple simultaneous warning messages on the dashboard, including Adaptive Cruise Control Problem, Lane Keeping Assist Problem, Collision Mitigation System Problem, Road Departure Mitigation System Problem, Auto High-Beam Problem, and a Brake System warning light. These warnings do not clear and are present every time the vehicle is started. As a result, the following safety systems are completely disabled: Forward collision avoidance / automatic emergency braking — the vehicle no longer detects or warns of potential frontal collisions Auto high-beam headlights — no longer switch automatically Adaptive cruise control and lane keeping assist — inoperable Road departure mitigation — inoperable In addition to disabling these safety systems, the persistent warning messages significantly obstruct the main instrument cluster display, making it difficult to see basic driving information including speed, fuel level, and odometer/mileage. This is a serious distraction and visibility concern in itself, separate from the loss of the safety systems. I have not yet had the vehicle professionally diagnosed, but based on extensive research into this issue — including reviewing the NHTSA complaint database — this appears to be a widespread and well-documented defect affecting 2018-2020 Honda Odyssey vehicles. The pattern matches hundreds of other complaints describing failure of the front-mounted Multipurpose Camera Unit (MCU), frequently associated with diagnostic trouble code U3000-49 (Multipurpose Camera Unit/Millimeter Wave Radar Internal Electronic Failure). Other owners report repair costs in the range of $1,500 to $2,600 for camera replacement and recalibration. This represents a serious safety concern: a single component failure disables the vehicle's primary collision-avoidance and driver-assistance systems simultaneously, while also obstructing basic instrument cluster vis

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
The vehicle’s front camera/Honda Sensing system has failed, causing multiple safety features to become unavailable simultaneously, including forward collision warning, collision mitigation braking, lane departure warning, lane keeping assist, adaptive cruise control and related systems. The failure produces multiple warning messages and disables safety systems that the vehicle was equipped and marketed with. This is a recurring issue reported by other Honda owners and is currently the subject of a proposed class action lawsuit, Jones et al. v. American Honda Motor Co., Inc., Case No. [XXX]. The lawsuit alleges a defective front camera system affecting 2018–2025 Honda vehicles, including the Odyssey. I believe this constitutes a safety defect because the failure can occur unexpectedly and simultaneously disables multiple driver-assistance and collision-avoidance safety systems. I am requesting that NHTSA investigate this issue and require Honda to issue a safety recall and provide a free repair.
