AIR BAGS
My SRS light went on without being in an accident. Around the same time I noticed that there was a recall reported (NHTSA Recall Number 26V-227) which states that the vehicle may deploy airbags without cause by going over a pothole etc. I took my vehicle in to the Honda dealership and they confirmed that my SRS ECU needs to be replaced bc it detected an airbag deployment but since it already deployed they will not replace it under the recall. However, the recall states that they need to update the SRS ECU to prevent this exact scenario from happening without proper cause and if it already happened the SRS ECU will need to be replaced. The worst part is, that they cleared the recall through the database for my vehicle but did not actually fix any issues and the SRS system is still not functioning. I already made a complaint with Honda corporation over two months ago but so far they have not provided a resolution.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Multiple sensors malfunctioned. Mechanic read code U3000-49 (Multipurpose camera unit/millimeter wave radar internal electronic failure). There was no collision or damage of any sort that led to this malfunction. The following systems no longer work: Adaptive Cruise control Collision mitigation system Lane keeping Assist Road departure mitigation system Blind spot info system Tire pressure monitor system Transmission system All of these failures started at exactly the same time. This severely compromises the ability to use this vehicle safely as these systems are all designed to prevent various safety hazards.

ELECTRICAL SYSTEM
When vehicle is completely stopped at a traffic light there have been numerous occasions in which all electrical components fail and the vehicle turns off and fails to restart. This only occurs when the auto idle start is engaged. A few times I’ve had to completely jump the vehicle. I have replaced the battery and also had the car examined at the dealership. They stated they had previously updated the system, had heard of other instances of the same issue but since it wasn’t under recall and they couldn’t replicate the issue they couldn’t do anything. This has proved to be extremely dangerous because at rest, without being able to restart when the light turns green my family and I are at risk of being severely rear ended at high speeds.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, LANE DEPARTURE: WARNING, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I believe the forward facing camera is having electrical issues which is causing the vehicle not to engage lane departure, traction control, Lane keeping assistance, emergency braking, adaptive cruise control, AC intermittently blowing warm and cold. There are four or five lights on the dash about this.

ELECTRICAL SYSTEM, ENGINE, POWER TRAIN
The vehicle is a 2020 Honda Odyssey. A recurring and dangerous safety failure occurs involving the Auto Idle-Stop system. With the system enabled and the vehicle at a complete stop, the engine shuts off as designed. However, upon depressing the brake pedal to resume driving, the engine severely struggles to restart and completely fails. Simultaneously, the vehicle immediately and automatically shifts itself into PARK, and the entire dashboard display illuminates with all available warning icons and messages. This malfunction creates an immediate, high-risk safety hazard. When the incident occurs, I am trapped, locked in PARK, in live traffic lanes, sometimes at busy intersections or during left-hand turns. It is impossible to shift back into drive or quickly restart the engine. I am forced to remain stationary in traffic for multiple minutes until the system allows me to cycle the ignition completely OFF and then back ON to attempt a full restart and shift back into Drive. This leaves my vehicle, my passengers, and other drivers vulnerable to rear-end collisions.

AIR BAGS, SEATS
2020 Honda Odyssey EX-L, 49k miles, no prior collisions. 1. Faulty system: SRS airbag module, defective factory aluminum clip (official Honda recall defect). EDR data verified this component failure by dealer technicians. 2. Safety risk: Driver airbag spontaneously deployed at 41MPH with zero impact. Seven occupants suffered soft tissue injuries and PTSD; sudden deployment created severe risk of secondary crash. 3. Dealer confirmation: Bay Ridge Honda (Brooklyn NY) diagnosed and confirmed the airbag clip defect via EDR readout and physical teardown, filed service records for this issue. 4. Inspectors reviewed vehicle: Honda dealer techs, EDR forensic specialists, and GEICO adjuster all inspected the car and confirmed no pre-crash damage. 5. Pre-fault warnings: No SRS warning lights, error codes or abnormal electrical symptoms appeared before the airbag deployed unexpectedly.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
I am the original owner of a 2020 Honda Odyssey Elite. On July 7, 2026, at approximately 76,127 miles, five safety-system warning messages suddenly appeared simultaneously upon startup: Adaptive Cruise Control Problem, Auto High Beam Problem, Road Departure Mitigation System Problem, Collision Mitigation System Problem, and Lane Keeping Assist System Problem. Restarting the vehicle several times did not clear the warnings. After the vehicle sat for approximately 30 minutes, the warnings disappeared. On July 8, after driving approximately 400 miles home, I parked the vehicle outside in approximately 110-degree heat. About two hours later, upon startup, the same five warnings reappeared simultaneously, along with the Brake System warning light. An authorized Honda dealer confirmed the multiple warnings and performed a DTC scan. Code U3000-49 was stored, indicating an internal failure of the multipurpose camera located behind the rearview mirror. Further testing confirmed that camera replacement was required. The dealer replaced and recalibrated the multipurpose camera at 76,567 miles. The repair cost was $1,631.80 for parts and $717.50 for labor, totaling $2,349.30. I am concerned that failure of a single internal camera component simultaneously disabled multiple driver-assistance and collision-avoidance safety systems. I believe NHTSA should investigate whether multipurpose camera failures associated with DTC U3000-49 represent a recurring safety defect in 2020 Honda Odyssey vehicles.

ENGINE, UNKNOWN OR OTHER
Multiple times the engine has totally shut down due to the auto idle stop system power loss. I have had the battery replaced a couple times and had the Honda dealership do the software update and I'm still having issues. This is a major safety issue as the car unexpectedly shuts down and takes a minute or so to get started again causing traffice backups.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
The front-facing Honda Sensing camera in my 2020 Honda Odyssey overheated in a 90deg climate. This triggered multiple dashboard warning lights: Adaptive Cruise Control (ACC) Problem, Lane Keeping Assist System (LKAS) Problem, Road Departure Mitigation (RDM) System Problem, Collision Mitigation Braking System (CMBS) Problem, BRAKE System Problem, and Auto High-Beam Problem. The Honda dealership quoted me $1850 to fix it and they said it was a well-known error. There were NO issues with my car prior to this problem. I keep up with all routine maintenance, oil changes, timing belt and water pump replacements, etc. Not only are these safety features inoperable, but these warning lights are very distracting to the driver, but worse than that- I would be unaware of other system failures since I have so many warnings displayed.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
Front camera default and required replacement totaling $2,400.00 in repair costs. This is a safety issue as the Adaptive Cruise Control, Front Collision Warning, Automatic Emergency Braking, and Lane Departure Warning were all disabled due to the front camera malfunction. This should be a recall by Honda as it seems to be a common mechanical failure in Honda Odysseys from 2018-2022.

LANE DEPARTURE: WARNING, LANE DEPARTURE: ASSIST, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
On 5/28/26, I went to get my van checked at a repair shop through my HealthCar warranty and I was told that I needed a system update on my brake system/ADAS/LKAS/ACC systems. All the lights beeped and were lighting up on my dash. It would go on and off from time to time, usually when it was more hot out. They told me to take to dealership and they need to do a system update and should fix no additional charge. I took it to the Honda dealership service department on 7/6/26 and was told it is the multipurpose camera has an internal failure and it would cost me $2,443.00 to repair it, plus I had to pay them a diagnostic fee. I have researched and been told by other repairs shops that this problem has been occurring often and it seems due to heat is the reason this happens.
