| Mar 2026 | FORWARD COLLISION AVOIDANCE | The contact owns a 2018 Honda Odyssey. While driving at an undisclosed speed, there was a loud sound coming from the vehicle with unknown warning lights flashing on the instrument panel. The vehicle was drivable during the failure. On another occasion, the brake warning light flashed on the instrument panel, and the brakes slightly depressed independently, and the driver then fully depressed the brake pedal. The vehicle was taken to an independent mechanic, where it was diagnosed with a monocular camera failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 125,000. | Crash: No Fire: No | 125,000 |
| Mar 2026 | VEHICLE SPEED CONTROL,UNKNOWN OR OTHER,ENGINE | One week ago, I was driving on a highway, accelerating to the 65 MPH speed limit on that road, my van's accelerator completely stopped responding. Despite pumping the pedal repeatedly, I was unable to control my speed at all, and the car continued to lose speed. I had my three children in the car at the time, and given that people regularly go in excess of 70 MPH on that road, I was in danger of not being able to exit the road and/or being hit. I was able to coast off of onto an exit, and the car started responding at speeds of 30 MPH, but it was lurching and jerking while driving. We immediately had the vehicle inspected by an independent mechanic and have been advised that the transmission needs to be replaced. There were no warning lights for this failure. The car also had an incident about a year ago where all lights came on and it stopped responding. At that time, we had Honda dealership examine it, and they said they could not find any issues. Additionally, the car has been jerking slightly while shifting, but the issue improved when we had the transmission fluid flushed at the Honda dealership again about a month ago, and no issues were noted by them at that time. We have performed regular maintenance and safety inspections on this vehicle. | Crash: No Fire: No | Unknown |
| Mar 2026 | ELECTRICAL SYSTEM,LANE DEPARTURE,FORWARD COLLISION AVOIDANCE | Upon further investigation, LOTS of 2018 Honda Odysseys are experiencing the same problem I am. There is a leak coming in from the top of the van in the rear that causes water to leak through and overtime damages the control unit in the back. Damage to this causes my power lift gate to completely stop working, my passenger drive door to stop working, and a bunch of features like the front collision warning, the lane departure, sensors, fog lights, so on to fail and go on and off. I had problems here and there with it but it wasn’t until it rained 4 days straight that I made the connection with the leak and started trying to figure out the problem. I took it to the Honda Dealership to get diagnosed and they confirmed this problem. We have not been in any accidents to cause body damage to the vehicle. | Crash: No Fire: No | Unknown |
| Mar 2026 | ENGINE | Over a year ago, my vehicles engine began ticking. On 12/14/2024, while driving the vehicle, it developed a rod knock, went into a limp mode and was towed back to our house. I eventually took the vehicle to Honda in Beaumont, Tx where they did an inspection of the vehicle and verbally told me it was the crankshaft, but would not provide me any documentation stating that. According to the lady at the desk, the service tech had never seen or heard of an issue like this in these vans. I was quoted almost $10,000 to replace the engine with a salvage yard engine with almost as many miles on it. I knew prior to taking it to Honda that there was a recall that did not cover my vehicle regarding this same issue. The vehicle is still parked at my house being started occasionally to keep battery charged. | Crash: No Fire: No | Unknown |
| Mar 2026 | FORWARD COLLISION AVOIDANCE | Intermittent electrical failure with the front monocular camera confirmed via DTC codes. Upon inspection, Camera is hot to the touch and all ADAS systems on the vehicle cut on/off with warning lights while driving. Was going down interstate utilizing ACC, system cut off throwing warning codes, then disappeared, then came back on. System continues to have intermittent issues indicating a failing camera. Even after 1-2 minutes of idle - camera is extremely hot when touching module underneath decorative garnish. | Crash: No Fire: No | Unknown |
| Mar 2026 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | The Camera module failed in our van and gave us a U3000-49 code which caused the vehicle to lose Adaptive Cruise Control (ACC), Lane Keeping Assist System (LKAS), Collision Mitigation Braking System (CMBS), and Road Departure Mitigation (RDM) functions on the vehicle with a cost to fix from Honda of $ 2,475.56. | Crash: No Fire: No | Unknown |
| Mar 2026 | ELECTRICAL SYSTEM,ENGINE | Vehicle experiences engine stalling and failure to restart at intersections when the Auto Idle Stop (AIS) feature is engaged. This creates an immediate life-safety hazard as the vehicle becomes non-functional in live traffic. This has occurred 2 times. Once on surface streets and once on the highway in stop-and-go traffic. This issue persists despite Service Bulletins 23-008 and 23-009. Honda Corporate and Honda Dealership refusing to cover the repair. Separately, during a 37-day repair attempt (Jan 22 – March 2, 2026), AutoNation Honda Chandler admitted the vehicle was sold with an 'incorrect' battery type (Lead Acid instead of required AGM), which caused electrical instability. The dealership attempted a repair on Feb 13, but the vehicle failed to start again on Feb 11 during a pickup attempt. The dealer has since refused to provide accurate service records or further communication. The vehicle remains unsafe to drive as it continues to stall randomly. | Crash: No Fire: No | Unknown |
| Mar 2026 | STRUCTURE | Power lift gate and power sliding doors failure alerts keeping showing up. They flash on and off on the display even while driving which can be very disruptive. The issue occurs randomly every few weeks The dealer quoted close to $2000 to attempt to fix it | Crash: No Fire: No | Unknown |
| Feb 2026 | STRUCTURE | I am filing a formal safety complaint regarding a dangerous manufacturing defect in my 2018 Honda Odyssey EX . A structural failure of the factory roof seam sealer (ditch molding) is allowing rainwater to pour directly into the vehicle's cabin, severely compromising critical electrical modules and creating major safety hazards. This water intrusion has caused two distinct and dangerous electrical failures: 1. Entrapment Hazard (Power Sliding Doors): Previously, water leaked into the rear fuse box area, causing the power sliding doors to completely fail and become completely unopenable. Transporting a [XXX] and a [XXX] in the rear seats, the sudden inability to open the sliding doors creates a terrifying entrapment hazard. In the event of an accident, fire, or emergency, I would be unable to evacuate my young children from the rear cabin quickly, posing an immediate threat to their lives. 2. Cargo and Security Hazard (Power Tailgate Control Module): Currently, the water leak has short-circuited the Power Tailgate Control Module. The system operates erratically: the tailgate automatically pops open as soon as the engine is turned off, and it refuses to open manually. Beyond the security risk, this electrical short could cause the tailgate to unlatch unexpectedly while the vehicle is in motion or stopped in traffic, potentially dropping cargo onto the roadway and creating a crash hazard for other drivers, or allowing carbon monoxide exhaust to enter the passenger cabin. This is a well-documented and widespread structural defect affecting many 2018-generation Honda Odysseys. Water destroying critical safety modules (doors and tailgates) is a severe design flaw that goes far beyond normal wear and tear. I strongly urge NHTSA to open a formal investigation into the roof seam sealer failures on the 2018 Honda Odyssey. A safety recall is necessary to force Honda to repair the structural leaks and replace the compromi INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) | Crash: No Fire: No | Unknown |
| Feb 2026 | ENGINE | Before my vehicle reached the 100,000-mile mark, the check engine light began appearing intermittently. I brought the car to my local dealership multiple times, but they were unable to provide a diagnosis and repeatedly reset the light. Once the light remained on permanently, the dealer finally identified a known Honda recall/extended warranty issue and replaced the spark plugs at no cost. However, approximately six months after that repair, the check engine light returned. The dealership has now diagnosed a failure in both the front and rear catalytic converters at a cost of $5200 to replace them. I need to replace to pass my state of Illinois car emissions tests. I have been working with Honda Goodwill Assistance (Case #161-655-70), but their offer to cover only 20% of the replacement cost is unacceptable. This failure is not a standard "wear and tear" issue; it is a direct consequence of the spark plug issues I repeatedly attempted to address before my warranty expired. I was told the 20% determination was based on my vehicle exceeding 100,000 miles, but this fails to account for the fact that I brought the car in for this specific issue multiple times while it was still under warranty. I am looking for Honda corporate to acknoweldge the new spark plugs they directed my dealer to install caused this issue and cover the cost of the repairs. My local Honda dealer service manager, Brian, is willing to speak on this issue on my behalf. He can be reached at [XXX] .

| Feb 2026 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | Issue Description: My 2018 Honda Odyssey (VIN: [XXX] ) has a total failure of the Multipurpose Camera, permanently disabling the Collision Mitigation Braking System (CMBS), Forward Collision Warning (FCW), and Lane Keeping Assist (LKAS). In addition to these, the regular Cruise Control is also disabled. These are primary safety systems, not elective conveniences. Persistent Failure: Errors occur immediately upon every startup. Mid-Drive Danger: Systems have deactivated multiple times while in motion, causing sudden, unpredictable loss of driver-assist features at highway speeds. Total Loss of Control: Both Adaptive and Standard Cruise Control are completely disabled, forcing manual-only operation. Infrastructure Failure: The failure prevents the vehicle from recognizing lane markings (RDM/LKAS), leaving the car unable to assist in steering corrections. Safety Risk: The vehicle can no longer perform emergency braking or provide collision alerts, significantly increasing the risk of high-speed crashes. This is a premature failure of a non-wear safety electronic at 91k miles. It is a severe safety defect that leaves the vehicle unequipped with the crash-prevention technology it was designed to have. Manufacturer Response: American Honda (Case #16167889) and NCDS (Case #XXX) denied assistance, citing the expired 3yr/36k warranty. I contend this is an extension of the known electrical architecture defects in this model year (e.g., Recall 23V-431), and a component intended for the life of the vehicle should not fail such that it disables multiple safety systems simultaneously.

| Feb 2026 | ENGINE | Engine failed while driving, will no longer start. Mechanic believe it is either connecting rod or main bearing failure. It has not been inspected by the manufacturer and will be sold to another person as is. No warning lamps or messages were present prior to the failure and didn't appear until after the failure. | Crash: No Fire: No | Unknown |
| Feb 2026 | ELECTRICAL SYSTEM,VISIBILITY/WIPER,BACK OVER PREVENTION | The vehicle previously received a manufacturer dash wiring recall repair. After the recall repair was completed, the vehicle began experiencing intermittent and cascading electrical and communication failures across multiple integrated systems. Affected systems include Apple CarPlay, the DVD system, in-vehicle camera systems, CabinWatch, and repeated “MOST network unavailable” error messages. These failures occur intermittently and result in multiple systems disabling simultaneously. The vehicle was inspected by a Honda dealership, which confirmed the issue involves wiring within the dash harness. The dealership stated the affected wiring is not sold or serviceable separately and that correction would require replacement of the entire dash harness, but that this portion of the harness is not included in the original recall coverage. Because these systems share common power and communication pathways, failures cascade across multiple modules. When the camera system fails, rear view camera functionality and related warnings are unavailable while backing up, reducing the driver’s ability to detect obstacles, pedestrians, or children behind the vehicle. When CabinWatch is unavailable, the driver is unable to visually monitor children seated in the rear rows while driving, which affects situational awareness and the ability to respond quickly to unsafe conditions inside the vehicle. These failures also impact driver information systems and create intermittent loss of critical visual feedback, increasing driver distraction as systems drop out unexpectedly while the vehicle is in operation. The condition began after the recall repair and appears to be related to or a continuation of the original recall defect. The vehicle remains available for inspection, and the condition has been confirmed by a manufacturer-authorized dealer. | Crash: No Fire: No | Unknown |
| Feb 2026 | FORWARD COLLISION AVOIDANCE | The multipurpose camera that works to provide all the safety features failed In less than 8 years. These should be lasting for the life of the vehicle. There should be a recall for this. | Crash: No Fire: No | Unknown |
| Feb 2026 | POWER TRAIN,LANE DEPARTURE | Bought vehicle new at Millennium Honda, Hempstead New York.Vehicle is not going into reverse when vehicle gets hot. My mileage is 40,512 took it Millennium Honda on October 4, 2025, for diagnostic testing error code P0736 was diagnosed and that my transmission would need’s replacing at a cost of $11,495 for parts and labor, because I was a couple months out of warranty. I have since reached out to Corporate but negative response. I am unable to use my vehicle since which have been at an additional expense to me as I have to maintain insurance and pay for bus, train and taxi services. Not sure what kind of assistance you can offer or even assist in investigating why a vehicle with 40,000 would need a new transmission after moderate use. Thanks for your consideration on this matter. | Crash: No Fire: No | Unknown |
| Feb 2026 | ENGINE | Engine has a rod knock problem at 72,000, miles. Vehicle will likely need a full engine replacement. | Crash: No Fire: No | Unknown |
| Feb 2026 | ELECTRICAL SYSTEM | Defective body seam on roof panel over drivers side rear wheel - resulting water leak on control panel for power liftgate caused the rear tailgate to continually open and close while driving. The vehicle was parked and the fuses controlling the tailgate were removed to enable the closure of the hatch and allow vehicle operation. Prior to this, the vehicle battery died while parked due to the continuous tailgate operation and required a battery jump. The vehicle was taken to D&J Auto (an independent service center) where a previous liftgate control panel was replaced for failure to open the tailgate. A search of the internet on 2018 Honda Odyessey liftgate problems revealed multiple instances of water leaks on the liftgate control panels due to body seam issues which caused liftgate failures. This information was relayed to the auto repair shop where the leak was discovered. The vehicle was taken to a body repair shop across the street where the seam was fixed, returned to the auto repair shop where a third tailgate control panel installed. | Crash: No Fire: No | Unknown |
| Feb 2026 | UNKNOWN OR OTHER | Water leaked through manufacting seams on rear drivers side of roof causing tailgate module to malfunction and creating a safety hazard. The rear tailgate would not stay latched or function at all. Took vehicle to honda of Bristol and they confirmed the problem. | Crash: No Fire: No | Unknown |
| Feb 2026 | ENGINE | A small "knocking" noise was noticed a couple weeks or so ago in my 2018 Honda Odyssey. Noise got progressively worse. Vehicle was taken to the Honda Dealership for assessment/repair. Was notified by a service technician that a rod knock was present on the lower end of the engine and that the engine needed to be replaced. Options were: new engine, used engine, or trade in my vehicle towards purchase of a new one. All maintenance records are meticulous and performed by a certified Honda service department. | Crash: No Fire: No | Unknown |
| Feb 2026 | POWER TRAIN | Upon pressing the accelerator from a complete stop, the vehicle does not respond right away. The main incident was when traveling around 50 miles per hour on a highway, the van shifted into neutral on its own and the accelerator would not respond. An error message of transmission failure showed on the dash briefly. The van had to coast through traffic an eventually push off the road. | Crash: No Fire: No | Unknown |
| Feb 2026 | ENGINE | This is in relation to Investigation PE25008. The engine in my 2018 Honda Odyssey Elite failed at 91,307 miles due to a connecting rod bearing issue, despite perfect dealership maintenance. | Crash: No Fire: No | Unknown |
| Feb 2026 | UNKNOWN OR OTHER | I am reporting a safety incident involving the power sliding door system on my 2018 Honda Odyssey. Today, Monday, February 9th 2026, my 3 year old child’s arm was caught and compressed by the power sliding door. At the time, she pressed the interior door button while I simultaneously pulled the exterior door handle. The door began to open, my child placed her arm out, and the door then closed on her arm instead of reversing. The door did not release or reverse automatically. I was unable to open it using the exterior handle and had to stretch to the front dashboard, left sliding door open button to stop and reopen the door to free her arm. Thankfully this didn’t happen on the passenger side sliding door! This resulted in redness, swelling, and pain, and she later woke from sleep crying due to increased pain. She is undergoing medical evaluation. The vehicle is equipped with pinch protection sensors that failed to prevent this injury. This appears to be a serious safety malfunction involving a child. I am submitting this report so the issue can be documented and reviewed for potential investigation. I have not seen a recall involving the sliding doors sensors having this issue. | Crash: No Fire: No Injuries: 1 Medical attention | Unknown |
| Feb 2026 | ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE | The front facing camera has stopped working. Anytime we turn the vehicle on we get multiple warning lights (lane assist, cruise control, bright lights, braking, etc) aren't working. | Crash: No Fire: No | Unknown |
| Feb 2026 | ELECTRICAL SYSTEM,BACK OVER PREVENTION | The contact owns a 2018 Honda Odyssey. The contact stated that while reversing, the back over prevention camera screen failed to display an image. The contact stated that the screen occasionally shut off unintendedly, and frequently disconnected from connected Bluetooth devices. The dealer was notified of the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 52,750. | Crash: No Fire: No | 52,750 |
| Feb 2026 | ENGINE | The vehicle started running rough and the check engine light with other error lights were coming on the dashboard display. 1. Engine Failure due to connecting rod/bearings 2. Vehicle ran rough and struggled to start 3. Problem was reproduced and confirmed by dealer (as seen in attached invoice) 4. Vehicle has been inspected 5. No warning lamps or messages prior to incident Sortly after I replaced my engine (per dealer recommendation) Honda released a recall (NHTSA Recall No. : 23V-751) but said that my vehicle was not covered under -- even though it appeared to have the exact same issue as my vehicle... they said that the recall was only for a smaller set for engines produced as a specific manufacturing plant... and I believe that it is likely more wide spread. | Crash: No Fire: No | Unknown |
