​The multipurpose windshield camera module in my 2019 Honda Odyssey experiences an internal electronic/power failure (Diagnostic Trouble Code U3000-49) while driving. This failure triggers a cascade of warning lights across the dashboard, instantly and without warning disabling the entire Honda Sensing driver-assist suite—including Collision Mitigation Braking (CMBS), Lane Keeping Assist (LKAS), Road Departure Mitigation (RDM), Adaptive Cruise Control (ACC), and Auto High Beams.

I'm filing a formal safety complaint regarding my 2019 Honda Odyssey, VIN [XXX], & requesting an engineering-level review by American Honda. I've brought this vehicle to an authorized Honda dealer numerous times for recurring & increasingly serious electrical, engine/power-loss, & transmission problems. Despite thousands of dollars in repairs, the problems continue. The vehicle has unexpectedly shut off/lost power; the power sliding doors have failed & required manual opening; low-battery warnings have appeared; & the radio/infotainment system repeatedly loses power and resets. I have photographs showing the message: “Anti Theft System–This system has lost power.” More seriously, the vehicle has malfunctioned in Park, Reverse, while shifting into Drive, & while turning. Most recently, the transmission would not engage properly and the vehicle had to be shut off and restarted multiple times before it would go into Drive. Delray Honda documented this transmission failure/no-drive incident on its August 2026 repair order. In May 2026, I brought the vehicle to Delray Honda for a Check Engine Management System warning. Repairs were performed, but the warning returned within days. Delray Honda then replaced the power distribution module, costing me approximately $2,000. I've spent thousands more dollars addressing these recurring problems without resolution. I understand Honda/the federal safety agency Recall 19V‑299 involved certain 2018–2019 Odysseys and a loss of power to the Transmission Control Unit. My Odyssey appears to have been manufactured around the time of those Hondas that were covered by that recall. I'm not claiming without diagnosis that the defect is identical, but the similarity of the symptoms warrants an urgent investigation. I request that Honda open a formal safety case, review my complete service history, DTCs and TCM/PCM data, determine whether my vehicle has the same or a related defect, and review my prior repair costs for reimbursement. Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT

I own a 2019 Honda Odyssey equipped with Honda Sensing. The vehicle has repeatedly displayed multiple driver-assistance system failure warnings, including “Adaptive Cruise Control Problem,” “Lane Keeping Assist Problem,” “Collision Mitigation Braking System Problem,” “Road Departure Mitigation System Problem,” and “Auto High Beam Problem.” The warnings initially appeared intermittently and then began recurring. In some cases, the warnings appeared at startup and remained active while driving. When the warnings are present, multiple Honda Sensing safety features are disabled simultaneously. To address a possible low-voltage condition, I replaced the vehicle’s battery with a new battery. After replacement and normal driving, the warnings continued to occur. The issue therefore does not appear to be solely related to battery condition. I also observed clouding and dark spotting within the front Honda emblem that covers the forward radar sensor. The discoloration appears to be inside the emblem assembly rather than on the exterior surface. Because the radar sensor is located behind this emblem, I am concerned that deterioration of the emblem or radar assembly may be affecting the operation of critical safety systems. This failure impacts several safety-related functions, including adaptive cruise control, collision mitigation braking, lane keeping assistance, road departure mitigation, and automatic high beams. The loss of multiple advanced driver-assistance systems creates a potential safety risk because the vehicle’s collision avoidance and lane assistance features become unavailable without warning. I am submitting this complaint to document a recurring failure affecting multiple Honda Sensing safety systems on my 2019 Honda Odyssey. There are numerous YouTube and social media posts on the same failure for same vehicle. It seems to be an issue for 2019 year

I was driving on a highway and all of a sudden, I see three warnings appearing on my dashboard - "Emission System Problem", "Blind Spot Info System Problem", "Transmission System Problem". I continued driving but then my vehicle started behaving weird. It started shaking while driving. Luckily, I was close to my exit and l somehow managed to take the exit but I wasn't able to move forward when the road was uphill. I somehow managed to park next to a house and walked back home. It was a really scare drive from the time those errors showed up to when I parked. This all happened few minutes ago. Here below is a thread where I can see others having this problem.

The vehicle is experiencing a dangerous hesitation during acceleration at low speeds, immediately followed by a sudden, violent forward lunging motion. When attempting to accelerate from a complete stop, or when rolling at low speeds (such as yielding at a roundabout, turning through an intersection, or merging into slow-moving traffic), the vehicle suffers from a distinct **lag or complete failure to accelerate** for several critical seconds. In an attempt to get the vehicle to move out of harm's way, the driver naturally applies more pressure to the gas pedal. The vehicle's transmission then randomly responds after a few seconds with a violent lunge forward, spinning the tires and causing the vehicle to surge unpredictably. This unpredictable behavior creates an immediate and severe safety risk to the occupants of my vehicle and others on the road: 1. Intersection Collisions: The sudden lag leaves the vehicle stranded in oncoming traffic during turns, while the subsequent lunge threatens to overshoot the intended lane. 2. Pedestrian Hazards: The sudden, uncontrollable lunging makes low-speed maneuvers in school zones, crosswalks, and parking lots incredibly hazardous. 3. Drivers behind behind me do not expect a vehicle to suddenly stop accelerating after it has begun to move forward. I have taken the vehicle to the dealership we're we were able to reproduce the issue and Honda would not offer a fix. I thought I was going to get my entire family killed the other day when I pulled out at a stop the van hesitated in the middle of the highway for a few seconds before lunging forward. This is an intermittent issueand the severity varies each time, but is commonly cited online.

The vehicle was in reverse and started to accelerate uncontrollably in reverse. The car came to a stop after hitting a wall and a car. The uncontrolled acceleration happened when we went about 1 foot onto grass while in reverse. The emissions light was going on and off from time to time. We believe it was inspected by a honda dealership at some point. The vehicle is involved with insurance at this point.

I am writing to open a formal complaint regarding a serious transmission defect in my 2019 Honda Odyssey (VIN: [XXX] ). My vehicle is currently exhibiting symptoms that directly match the 'Transmission Programming Defect' documented in ongoing litigation, specifically symptoms: while accelerating produce rough and delayed shifting; sudden jerking, sudden, harsh accelerations and decelerations; and a sudden loss of power. I am aware of Case No.XXX (XXX v. American Honda Motor Co.) and Case No. XXX (XXX v. American Honda Motor Co.), which allege that the 9-speed ZF 9HP transmission in my model year suffers from a design defect. These transmission failures create a significant safety hazard. Recently my van report code as transmission system problem the second time. We got mechanic checked and confirmed it is transmission issue. The first time when it happened, we drove the van on highway and suddenly it lose power and slow down by itself. there was no response even we applied gas. We went down highway and drove to a close-by repair shop. they replaced some part for us but it didn't resolve the issue. This time since the error comes, it won't speed up in lower speed except the speed goes beyond 40-50 miles plus. when we back the car, it responses slow or none. it comes with big noise also now. it definitely gets worst. The very common issue when you stop and start to move, it never responses from the beginning even we applied gas, even the passenger can feel the reluctance. it also happens when the van turns. we also had the experience when driving on the highway, it speeded automatically without driver applied the gas. It feels like someone pushing us behind. there was Transmission Control Unit recall for 2018-2019 Honda Odyssey (Touring/Elite). Honda actually knows the issue but they didn't reveal this to their customer. This brings life threatening concerns on the highway. I hope this complaint can save lives and family INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(

On April 13, 2026, I brought my 2019 Honda Odyssey to a Honda dealership in Chicago, IL for a dealer-initiated recall service. The dealer contacted me and asked me to come in. Before the recall service, the vehicle had zero warning lights, zero error codes, and was operating completely normally. Immediately after the recall service was completed, the following warning lights appeared on the dashboard: Brake System warning, Hill Start Assist Problem, VSA (Vehicle Stability Assist) warning, and additional stability/steering system warnings. None of these warnings existed before the service. I returned to the dealership the same day. The service team cleared all error codes. However, within minutes of driving off the lot, all warning lights reappeared. This confirms the issue is persistent and not a one-time post-update self-check. I returned a second time. The service manager stated the warnings were not caused by the recall service and refused to investigate further. The dealer quoted $800 for diagnostic work. I also contacted American Honda by phone and was told they could not intervene. With the Brake System and VSA warnings active, the anti-lock braking system and vehicle stability control may not be functioning properly. This puts me and other drivers at risk, especially in emergency braking situations and on slippery roads. This pattern of multiple safety warnings appearing immediately after recall service on 2019 Honda Odysseys has been reported by other owners. The vehicle and its warning lights are available for inspection upon request.
