| Apr 2024 | ELECTRICAL SYSTEM,LANE DEPARTURE | It is available for inspection on request. Lost blindspot info, lost use of turn indicators, rear door hatch malfunction, several warnings flash up while driving. I was in a busy area and didn't have a way to signal my movements, screen flashing warnings was terrifying, the van felt like it might turn off at any moment. Before the most recent incident, we had brought the van to Honda dealer for repair, for similar issues that occured at start-up, they found water in the power control unit in rear left area of van that caused corrosion and short-circuit. No body damage or alterations to vehicle. Replaced unit and after rainy weather problems recurred at start up and power down, then while driving, they tested the battery and it was almost dead (the battery was only 1 month old) replaced battery. Problems recurred and water found again. significant leak suspected but not found yet as the service department won't evaluate the seals, and told us it's a body-shop task. summary: intermittent left-side passenger door and rear hatch door malfunction, blind spot system warnings/loss, loss of turn indication, brake system warnings, other system warnings, difficulty starting the car and turning the car off, brand new battery drained while the car was parked and turned off. This manufacturing defect should be addressed by Honda, seals should not fail when exposed to regular conditions. Water should not enter the vehicle and short out an important component leading to several malfunctions that could cause loss of important systems and rear-door latch while driving. | Crash: No Fire: No | Unknown |
| Apr 2024 | BACK OVER PREVENTION,FORWARD COLLISION AVOIDANCE | I started the vehicle and it displayed a message on the infotainment system screen that the system had lost power. I believed that this would only affect the radio functionality which I was not concerned about immediately. I placed the vehicle in reverse and I accidentally backed up into a parked car. At no point before the accident did I realize the rear camera did not work and the collision assistance sensors did not function. I believe if the collision avoidance system was working correctly my accident would have been prevented. I have come to depend on the safety features of this vehicle. I know that this is not an issue with my car battery as I recently had a Honda dealer install a new battery prior to this accident and the vehicle started normally. | Crash: Yes Fire: No | Unknown |
| Apr 2024 | ENGINE | * An engine failure occurred due a connecting rod bearing seizure. The engine was replaced at Bryan Honda in Fayetteville NC. Unless the dealer is required to save the parts I don't have them for inspection. * The engine failure occurred on the travel portion of [XXX] stalling the vehicle on the highway. Luckily we were able to move the vehicle off the traveled portion of the highway but it was not safe to be slightly of the road until a tow arrived. * The problem with this type engine is known and subject to recall number [XXX] although Honda says my specific VIN isn't covered when I submitted a claim, possible the recall could be expanded. *The engine and components were inspected at the Honda dealer. *The check engine light started flashing just as the engine lost power.

| Apr 2024 | ELECTRICAL SYSTEM,STRUCTURE | Water getting into rear liftgate control module. Had to replace seal and module. | Crash: No Fire: No | Unknown |
| Apr 2024 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | The forward warning system will say brake without anyone or anything in front of you. It will then slam on the brakes. This is very dangerous and has almost resulted in multiple collisions. We have took it to the dealership numerous times and it has not been fixed. I have called American Honda and they will not fix the issue. I get the run around that it is outside of warranty. It was took to them under warranty but was never fixed. The local Honda dealer wants to just try swapping out cameras at a price of $2,500. They do not know if it will even fix it. Now the system has numerous warning lights related to the adaptive cruise, lane keep assistance, forward warning system and lane departure warning. Again I have called America Honda and local dealership. They do not know how to fix it. This is a major safety hazard and they should be forced to repair it under a recall. | Crash: No Fire: No | Unknown |
| Apr 2024 | ENGINE,FUEL/PROPULSION SYSTEM | At 60 mph, the fuel injectors failed on cylinder 1/2/3 (known issue based on TSB [XXX]). The vehicle produced various error codes but did not go into limp mode. We proceeded to the nearest exit on the highway to safely pull off. The engine shortly after turned on limp mode as we neared the exit. We heard an audible ping noise and the engine power changed (could still keep the vehicle moving but shaking in the steering wheel). We were on a straight path of road so the steering wheel shaking was manageable. We had the vehicle towed to nearest Honda Dealership and they completed the TSB putting in new injectors. The fault codes cleared on cylinder 1 & 2 but not 3. They performed compression test and assessed dead cylinder requiring new engine replacement. Technician also noted that #3 injector had locked open and spark plug was soaked with fuel from flooding the engine cylinder. I escalated to Honda Corporate (case # [XXX]) and they looked into the matter believing it wasn't that severe. After 1 month, they closed the claim at the regional manager level, with no earnest money, and said we were on our own for an engine with 74k miles since it was out of 60k warranty. I towed the car to my private certified mechanic (who had done all the oil changes since purchase at 34k miles). He checked with borescope and cylinder wasn't moving while crank turning. He has diagnosed broken piston rod and looking for used engine to try and replace. Honda Asheboro quoted $6,400 for repair. We believe that #3 cylinder hydro-locked when ECU turned off injector and spark plug but couldn't closed the injector properly (known debris in fuel system) causing the piston rod to break and luckily not drop the piston into the crankcase. Car is sitting idle waiting for repair or further review. Will be taking Honda Corporate to small claims court in Stanly County, NC. Other known issues for this model/year is fuel pump and piston bearings (both also TSB's and not recalls).

| Mar 2024 | STRUCTURE | Power Tailgate is not functioning and the trunk opens on its own. Yes, available for inspection. The trunk opening on its own puts the safety of everyone in the car at risk. I had the same issue 9 months ago, the dealer charged me $1200 to fix it. The dealer inspected it and stated it was due to a water leak that damaged the control module for the Power Tailgate. Nothing prior, a "Power Tailgate Problem" warning appeared on the dashboard, and the Power Tailgate stopped working. | Crash: No Fire: No | Unknown |
| Mar 2024 | FUEL/PROPULSION SYSTEM | My van has been stalling out constantly and not allowing me to power/move the car forward on several occasions. Most recently, my car has stalled out in two intersections, causing other cars to swerve/slam on the breaks and almost hit my car with my three young children in the car. I especially have trouble getting up any sort of hill. It is also a big problem when I have to stop my car for any amount of time (i.e. stop signs, turning lanes, stop lights) and then try to power my car when it is my turn. The car almost always stalls and has almost caused several accidents. | Crash: No Fire: No | Unknown |
| Mar 2024 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER | Right Power door will not open or close with buttons or key fob. Must open/close manually. The doors are too hard to open manually for smaller children and even some adults making it a safety concern in case of emergency. This started intermittently a year ago and is now a constant. Tailgate has been opening and closing on its own, even when locked while parked as well as when the idle stop is activated while in drive. This is a concern that someone can get in the vehicle when unattended. It also shuts (and didn't stop) when someone was standing in the opening while removing something when it occurred. This started about a month ago. I was told to take it to a dealer and pay them to diagnose it. The dealers have a wait list and it's also not in my budget. These are real concerns and I feel Honda isn't taking ownership of the dangers. | Crash: No Fire: No | Unknown |
| Mar 2024 | ELECTRICAL SYSTEM,FUEL/PROPULSION SYSTEM | Our 2018 Honda Odyssey has the defect described in this recall: [XXX] However, the VIN search says that it is not eligible. This defect causes all of the vehicle's electronic safety systems to malfunction. Occasionally it will not start at all.

| Mar 2024 | UNKNOWN OR OTHER | After rain, the next day, I get error tailgate problem on my dashboard. I can no longer open it using my remote or from the front panel of my van. I saw many complaints of similar issue out there. This should have been a recall due to manufacture failure. | Crash: No Fire: No | Unknown |
| Mar 2024 | ELECTRICAL SYSTEM,STRUCTURE | A water leak above the tailgate control module flooded it to the point that it operated erratically and would raise and lower the tailgate randomly or not work at all. I plan on replacing the module myself but will retain the old one. Anytime the entry or exit points on a vehicle open randomly cannot be a safe condition. The dealer charges $130 for any inspection or diagnostic so no I am not paying them to tell me something is broken. The vehicle currently is showing a "Power Tailgate Problem" and a yellow box with "TAILGATE" in it on the dash display and is currently unresponsive to any input that would operate it: remote, tailgate buttons, and driver button. The power locking system is still operable. The Odyessy forums clearly describe multiple occurrences of this failure and the culprit is a water leak in rear window or rear section of roof trim strip on the drivers side. My module did have water in it when I opened the plastic case it is contained in. Cleaning and drying it restored operation for about 3 days. Thanks for your help! | Crash: No Fire: No | Unknown |
| Mar 2024 | ENGINE,FUEL/PROPULSION SYSTEM | We are having the same issue as indicated on the Service Bulletin 20-100 but our VIN is not listed as covered by the manufacturer. | Crash: No Fire: No | Unknown |
| Mar 2024 | POWER TRAIN | My van driving on the highway and pop up two error cods at the same time, one is transmission system problem and the other is blind spot info system problem. Check it out with code P0741. And this incident happened 7 times in the past 6 months. | Crash: No Fire: No | Unknown |
| Mar 2024 | POWER TRAIN,ELECTRICAL SYSTEM | Our Tailgate is having an issue that triggered a safety issue with my wife driving on a highway then 3 lights popped up and car entered a limp mode. transmission issue, emissions issue, tailgate issue since then car is behaving normally but the tailgate latch is opening when we start the van and not working from fob (unlock) or exterior tailgate button. I have read other owners having an issue where the tailgate control module is getting submerged by water causing the unit to short and cause these issues. A car entering limp mode on the highway poses a threat to our family and others, I hope to see a solution in the near future. | Crash: No Fire: No | Unknown |
| Mar 2024 | ELECTRICAL SYSTEM | There is an electrical drain causing the battery to drain to the point where it will not start. Alternator was replaced, then the issue persisted. Most recent problem include the power tailgate opening on its own. Rear power tailgate issue. The rear tailgate will attempt to open while driving, but the warning sound chimes and alerts to the problem. If the vehicle is left unlocked the tailgate will open itself. The power tailgate button in the driver seat does not work. The close button on the bottom of the door is illuminated (has power) but will not close the door. The soft rubber button above the license plate will engage the motor to lift the tailgate, but not to close it. Others have filed complaints about a water leak impacting the rear control board and causing it to fail. Leak may be from the fin on the roof or related to the cracking and rotting seal on the bottom of the rear windshield. | Crash: No Fire: No | Unknown |
| Mar 2024 | AIR BAGS,SERVICE BRAKES,FUEL/PROPULSION SYSTEM | See service Honda Service Bulletin 20-100 Dated 2-11-2021.The fuel Injectors part Number 16010 (6EA) has failed and my dashboard display , displays most of the sensors that means there is an actual problem, or a false reading. As a Honda owner, I cannot determine if it is an actual fault or a false reading. I had Rusty Wallace Honda dealer check the car using OBD device and the equipment indicates a code 219A, which indicates bad fuel injectors. Now after the check additional and different sensors are displayed with problems than were displayed prior to this check. The trouble shooting and after displaying the code 219A indicated a catastrophic failure. Rusty Wallace has verbalized the results and that I should continue driving the vehicle, that this would not damage the engine or the car. I am not a certified mechanic, but my younger days were devoted to back street work repairing and driving vehicles. Anytime that you starve or flood a cyclinder you had serious problems. I need this vehicle as a daily driver. | Crash: No Fire: No | Unknown |
| Mar 2024 | UNKNOWN OR OTHER | Hello, my name is [XXX] . I have a 2018 Honda Odyssey that I bought brand new 6 years ago from Open Road Honda in Edison, New Jersey. We received a notification of the tailgate malfunctioning out of the blue yesterday evening. It was raining the whole day yesterday. Upon checking the internet, we found this to be an issue faced by multiple Honda Odyssey owners and a dedicated thread discussing this in the Honda Odyssey Forum. Link to it is here: [XXX] After doing a little bit more research, we found a potential problem to be a malfunction due to water going into power tailgate module and this could be caused by some welding defects from Honda. We decided to remove the fusebox cover in the back left of the car (driver side) and found that there was water inside. We have sent the car to our mechanic to resolve the issue. Please see pictures and video attached for your review. This also has the VIN number for our car. But, since this seems to be a manufacturing defect and it is going to cost a lot to fix, we would appreciate Honda taking action on this. We would like to take this to a dealership for issue resolution with Honda facilitating and paying for the repairs since it is a manufacturing defect. Please advise us on next steps.

| Feb 2024 | POWER TRAIN | The transmission has been acting weird - not shifting appropriately and jerking when shifting for about 2500 miles previous to this. The car has had routine maintenance and all recall work completed at dealership. At 86000 the transmission needs to be replaced. In addition, when it would get really wet or go through a car wash the transmission wouldn't function properly and not go into reverse at all. | Crash: No Fire: No | Unknown |
