STRUCTURE:BODY, ELECTRICAL SYSTEM
The power tailgate system on my Honda Odyssey failed. The dashboard displays a “Power Tailgate Problem” warning message and the tailgate will not open automatically using the key fob, interior button, or rear handle. When attempting to open it electronically, the vehicle beeps but the tailgate does not move. The tailgate can only be opened manually. The vehicle and tailgate system are available for inspection upon request. The failure creates a safety risk because the tailgate cannot be opened electronically in situations where quick access to the rear cargo area may be needed. Additionally, if the power tailgate system fails unexpectedly, it could malfunction while opening or closing, potentially striking someone or failing during loading/unloading. The inability to rely on the automatic tailgate also creates hazards when carrying items or supervising children around the rear of the vehicle. The problem occurs consistently every time the power tailgate button is pressed. The system beeps but does not open. The issue has not yet been formally inspected by a dealer but can be easily reproduced. The vehicle has not yet been inspected by the manufacturer, police, or insurance representatives for this issue. A “Power Tailgate Problem” warning message appeared on the dashboard when attempting to use the power tailgate. At the same time, the vehicle emits a beep but the tailgate does not move. The issue began recently and has occurred every time the power tailgate has been used since the warning first

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS, ELECTRICAL SYSTEM
The multipurpose camera module has failed, on the vehicle resulting in the simultaneous loss of several driver-assistance and safety systems while the vehicle is in operation. These systems include cruise control, lane keep assist, lane departure warning, collision mitigation, automatic high beams, and the brake system warning. Upon inspection, there appears to be overheating within the camera module. This overheating has caused visible discoloration both inside and outside the module housing. Based on these observations, I believe the condition may present a potential fire hazard. Additionally, the plastic cover mounted to the windshield becomes extremely hot to the touch, creating a risk of skin burns if it is accidentally contacted. This malfunction poses a significant safety concern for my family. If the camera fails while driving, the vehicle’s safety systems may not function as intended, increasing the risk of an accident. All of the failures chime in one after another displaying a problem with the malfunctioning components stated earlier in the text. Furthermore, if a driver is deaf or not actively monitoring the instrument panel or speedometer, they may not hear or immediately notice the warning alerts indicating that these systems are no longer functioning. The issue has been diagnosed by my local repair shop finding error code U3000-49: Camera/Radar Internal Failure. Repair requires replacement of the multipurpose camera module, with an estimated cost exceeding $2,000 in parts and labor, which represents a significant financial burden.

The front-facing camera stopped working, and all associated ADAS systems no longer functioned (Adaptive Cruise Control, Automatic Emergency Braking, Forward Collision Warning, Lane Departure Warning, Lane Keeping Assistance). Several errors needed to be cleared every time the vehicle was started. Our Honda dealership determined that it was a failed Multipurpose Camera (code U3000-49), and that the entire camera unit needed to be replaced and re-calibrated.

BACK OVER PREVENTION, ELECTRICAL SYSTEM
The contact's daughter owns a 2020 Honda Odyssey. The contact stated that while his daughter was driving at an undisclosed speed, several unknown warning lights illuminated. The contact attempted to inspect the vehicle but could not determine the cause of the failure. The vehicle was taken to a dealer, where the contact was informed by the technician that the failure might be from the wiring connected to the rearview camera. The contact declined to pay for a diagnostic test. The contact attempted to repair and realign the rearview camera; however, the part needed to realign the camera could not be purchased and could only be serviced at a Honda dealer. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 130,000.

The sliding door will not open, either manually or automatically. This is a huge safety problem since my children cannot get in or out of the vehicle quickly in an emergency. What should I do if this happens on both doors, I will not be able to open either sliding door.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
the front monocular camera is defective causing the safety features (adaptive cruise control, collision warning, lane shift warning, auto brights, auto braking) to not function at all. This seems to be a known issue with many honda owners. The warnings show every time I start the van. This issue has been verified and the repair is costly.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
Multiple Honda Sensing safety systems (collision mitigation, lane keeping, road departure, adaptive cruise, and auto high‑beam) disabled suddenly on 2020 Honda Odyssey EX‑L around 76,000 mi. Dealer and two independent diagnostics confirmed DTC U3000‑49, internal electronic failure of the forward recognition camera. The fault disables all automatic braking and lane‑keeping functions. Battery voltage and calibration verified OK; component failure is internal. Honda quoted ~$2,000 repair. This is a significant safety risk since all advertised crash‑avoidance functions stop working.

LANE DEPARTURE: ASSIST, LANE DEPARTURE: WARNING, FORWARD COLLISION AVOIDANCE: WARNINGS
After purchasing my 2020 Honda Odyssey EX-L in July 2025 (had approximately 58,000 miles), in January 2026 (current mileage approximately 66,000 miles), it suddenly displayed multiple indicators on the dash, including 'ACC', 'LKAS', 'Brake System', 'Auto High Beam Problem', and 'Collision Mitigation'. My local mechanic indicated the cause was the collision radar system, but it needed to be calibrated at a Honda dealership. My local Honda dealership indicated the problem code as 'U3000-49 Internal Camera Malfunction', necessitating that the multi-purpose camera be replaced. The total repair cost was $2,104.99. Online research shows that this is a common issue with this model year. If the cause is due to a camera malfunction or disrepair, and it impacts the safety of myself and others in the vehicle, why is this not considered a valid reason for a recall? I shouldn't be responsible for a costly repair that didn't result from any mechanical issue or mistreatment on my part. Because of the safety implications, this should be a Honda recall, and I should be reimbursed for the repair cost.

STRUCTURE:BODY, LANE DEPARTURE: WARNING, LANE DEPARTURE: BLIND SPOT DETECTION
All of my ADAS systems were disabled due to a water leak. The repair required the dealership to hire a "leak doctor" and then replace a module in the rear tailgate. My vehicle showed an alert on the dash that each of the ADAS features were disabled, auto high beams were disabled, and I could not turn the vehicle off by pushing the start/stop button once, I had to use a procedure that forced the vehicle to shut down. My interior dash lights flickered, I'm not sure if the headlights worked. As the interior dried out, the flickering occurred less frequently. I was able to drive the vehicle to a Honda dealer for repairs.
