| Sep 2024 | ENGINE | My Honda Odyssey is experiencing an issue where it intermittently fails to restart automatically after coming to a stop and engaging the idle stop feature. Despite following Honda's recommendations, which included applying Service Bulletin 23-008 (updating the PGM-FI Idle Stop Software) and replacing the battery, the problem persists. I've also had the vehicle inspected at two different dealerships, with no resolution. I discovered Service Bulletin 23-009 on your website, which directly addresses this exact issue and extends the warranty for the Ridgeline, Pilot, and Passport models. Given that my Odyssey shares the same engine, it's concerning that it's not included in this bulletin. I believe it's unfair that I'm being forced to pay dealership fees to diagnose and fix a safety issue that Honda has already acknowledged and addressed for other vehicles with the same engine. I urge you to reconsider the exclusion of the Odyssey from Service Bulletin 23-009 and provide a solution that doesn't burden owners with unnecessary costs. | Crash: No Fire: No | Unknown |
| Sep 2024 | AIR BAGS | The contact owns a 2021 Honda Odyssey. The contact received notification of NHTSA Campaign Number: 24V064000 (Air Bags); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect. | Crash: No Fire: No | Unknown |
| Aug 2024 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | After a slight rain, the error of Radar Obstructed is being displayed. Can’t get this error removed or fixed. After searching more I found out that: 1. Honda has a defective design in the Advanced Driver Assistance Systems (ADAS) of all Honda Odysseys, models 2018-2023. 2. Namely, Honda has placed the RADAR behind the large HONDA emblem on the front grille. This causes the radar to give a "RADAR OBSTRUCTED" warning, which disables all Advanced Driver Assistance Systems in the car (Automatic Emergency Braking, Adaptive Cruise Control, Forward Collision Warning). 3. The "RADAR OBSTRUCTED" warning cannot be reset by restarting the vehicle or disconnecting the battery, requiring recalibration of the RADAR at the cost of $800 each time since it takes several hours to do (per Dealership). 4. The official Honda Odyssey Forum online has countless complaints on the same issue without resolution by Honda. 5. Honda has acted in bad-faith towards their customers since this defect impacts the vehicle's advanced safety features for which buyers incur additional expenses, endangering the lives of passengers. 6. Honda has acted in bad-faith towards their customers by designing a system that requires continuous and substantial expenditures without resolution because it is an engineering problem, i.e., the placement of the radar behind the large, thick plastic H emblem obstructs the radar. 7. I hereby ask that the NHTSA investigate this issue and order Honda to offer a solution in the form of a RECALL that permanently addresses the problem. | Crash: No Fire: No | Unknown |
| Aug 2024 | AIR BAGS | Took my odyssey to the local dealer a few months back for the recall and dealer told me they wouldn’t have the part until next year. Now this has caused an issue to where my whole airbag system is short circuiting and the dealership wants to fix all the other issues and not fix the open recall. Family safety is at risk. | Crash: No Fire: No | Unknown |

| Jul 2024 | ELECTRICAL SYSTEM | 1. Incident: I was driving and stopped at a red light, took my foot off of the brake and the car completely died, leaving me stranded at the intersection. The car started back up after 4 minutes. Note: This incident happened after 2 months of weird electrical things happening to the car, such as the radio turning on after the car had been turned off, car not starting, sliding doors losing power when they are halfway closed, coming to a stop and putting the car in park then the car completely loses all power/interior lights, and more... 2. My safety was put at risk by having a non-functioning car in the middle of the road. Someone could have rear-ended me. Also, it was over 100 degrees outside which added to the panic I was feeling. 3. The car has been inspected by Spreen Honda multiple times and by an independent Honda mechanic. Spreen Honda has not been able to reproduce the problem. They won't do anything besides hook it up to the computer, and since there are no codes present "there is nothing they can do". The independent mechanic said they'd never seen anything like this. 4. The manufacturer has not inspected the vehicle. When I reported this to Honda America they encouraged me to continue working with the dealer. This is completely unacceptable. 5. Right before the power went out the dash lit up with every warning lamp for maybe 5 seconds. | Crash: No Fire: No | Unknown |
| Jul 2024 | ELECTRICAL SYSTEM | 1. While I was driving on the freeway, my radio turned off and my car put itself into NEUTRAL! I was able to safely pull over and put it back in drive. Note: This incident happened after 2 months of weird electrical things happening to the car, such as the radio turning on after the car had been turned off, car not starting, sliding doors losing power when they are halfway closed, coming to a stop and putting the car in park then the car completely loses all power/interior lights, the car turning off while stopped at a light and more... 2. Had there been more traffic I would have been in major danger. I could have easily been rear-ended or hit someone in the process of trying to get off of the freeway. It could have caused a multiple car collision. Grateful my children were not in the car at the time of the incident. 3. The car has been inspected by Spreen Honda multiple times and by an independent Honda mechanic. Spreen Honda has not been able to reproduce the problem. They won't do anything besides hook it up to the computer, and since there are no codes present "there is nothing they can do". The independent mechanic said they'd never seen anything like this. When I reported the incident to Honda America, they recommended I should continue taking the car to the dealership, which makes no sense as the dealership does not actually attempt to diagnose the problem if there is no code. 4. The manufacturer has not inspected the vehicle. When I reported this to Honda America they encouraged me to continue working with the dealership service department only. They don't take information from 3rd party service providers. This is completely unacceptable. 5. Right before the car shifted to neutral, the radio turned off and the dash lit up orange. | Crash: No Fire: No | Unknown |
| Jun 2024 | SUSPENSION | The inside shoulder of all four tires are bald and unsafe. The rest of the tire tread has ~7/32 of depth remaining. Because this suspension issue only affects the inside edge of the tire it is difficult to detect. Not all Gen 5 Honda Odysseys have this problem but I've read of others with the same problems as mine. The tires cross the threshold of 2/32" by approx. 23k miles. When the rest of the tire still looks good the avg consumer is not inspecting the inner shoulder because it would require tire removal or getting under the vehicle. Therefore, the issue goes undetected until a traction event occurs. | Crash: No Fire: No | Unknown |
| May 2024 | SEATS | The third row seat latching mechanism will not lock the seat into place on the floor. We had a child who was sitting in the seat and the seat flipped backward.

| Apr 2024 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | I am writing to urgently bring to your attention a critical issue plaguing the driver assist systems in Honda Odyssey 2018+ vehicles. Despite meticulous maintenance and adherence to manufacturer guidelines, I have encountered a persistent and alarming problem that appears to affect numerous other vehicle owners, as evidenced by online forums and discussions. The issue initially arose during a rainstorm, where I received a warning message stating, "Some Driver Assist Systems Cannot Operate: Radar Obstructed." Despite the weather clearing and thorough cleaning of both the sensors and the windshield camera, the warning persisted. Subsequently, a series of related problems emerged, including: Illumination of the BRAKE SYSTEM LIGHT Malfunctioning adaptive cruise control Faulty collision mitigation system Inoperative road departure mitigation system These errors not only pose a significant safety risk to myself and others on the road but also indicate a systemic issue with the vehicle's safety systems. As my vehicle is just past the three-year mark and out of warranty, I am apprehensive about incurring substantial costs for dealership repairs, especially considering the widespread nature of these complaints among Honda Odyssey owners. Extensive research reveals that I am not alone in experiencing these issues. Multiple reports and discussions online highlight similar complaints from other Honda Odyssey 2018+ owners, particularly following exposure to adverse weather conditions. Therefore, I implore the National Highway Traffic Safety Administration to conduct a thorough investigation into this matter. It is crucial to identify the underlying cause of these recurring issues and hold the manufacturer accountable for any design flaws or defects contributing to the malfunction of critical safety systems. Furthermore, I urge NHTSA to prioritize public safety and take immediate action to ensure affected vehicles are promptly recalled or repaired to prevent further incident | Crash: No Fire: No | Unknown |

| Feb 2024 | UNKNOWN OR OTHER | The 2021 Honda Odyssey with the VIN provided had 1) Auto Stop Idle Failure in June 2023 where the car would turn off completely at a stop (intersection, stop sign, etc.) and the car would have to me restarted. Sometimes restarting more than once. Honda replaced the car battery and conducted a software update. 2) About 7 months later in February 2024 the dashboard displayed two warnings A) Auto Engine Idle Stop System Problem and B) Charging System Problem. Honda had performed a second software update just prior to the second occurrence on 1/25/24. As of 2/15/24 Honda still has the car and is going to replace a battery sensor. | Crash: No Fire: No | Unknown |
| Feb 2024 | UNKNOWN OR OTHER,VISIBILITY/WIPER | Recall for driver side view mirror completed. However the replacement mirror is distorted and causes blurred, wavy, double images.

| Dec 2023 | ELECTRICAL SYSTEM | All of the safety system and efficiency systems had failures which made us take to our local Honda dealership for evaluation. After the first visit we were told that they could not find the problem, although they saw all of the error messages. The error messages appeared again 3 days later so we took it back to our local Honda dealership. This time one of the service reps had seen that problem before and said it probably was due to water entering the rear trunk circuit board controller and shorting out the connections. This was confirmed by a service tech during the 2nd evaluation. After research this is apparently a common issue. We had to pay approximately $700 to fix the situation because Honda does not have this issue as a recall. We believe this is a clear design error that allows water to enter the circuit board housing. This created a dangerous situation as the head lamps as well as the driver safety features and direction signals intermittenly worked due to the shorted out circuit board. | Crash: No Fire: No | Unknown |
| Dec 2023 | UNKNOWN OR OTHER | My sunroof exploded on my 2021 Honda Odyssey while I was driving on the interstate, I-10 East, on Dec 16, 2023, around 4:30 pm. There was no impact from a rock or other debris. There was no rain or hail present. I was not near an overpass. I was driving and heard an explosion above me and then heard outside air like the windows were open. The center of my sunroof exploded and shattered onto my sunroof cover. | Crash: No Fire: No | Unknown |
| Nov 2023 | VISIBILITY/WIPER,LANE DEPARTURE | Rear view mirror on the windshield has a factory defect. It falls off and causes hazardous conditions. I backed into a parked and unoccupied vehicle. It was dark, the warning beeper did not sound until I hit the vehicle. The dealership has attempted to fix the issue 3 times, the item is ordered to fix the mirror. I have reported this issue to the NHSTA twice. This is my second update after the initial report. The sales manager, Bobby, (cell#336-740-4273), says that he is aware that other Honda vehicles have had this problem with the mirror. | Crash: Yes Fire: No | Unknown |
| Nov 2023 | VISIBILITY/WIPER | After 4 attempts by the dealership to correct the issue, The windshield inside view mirror malfunctions when adjusted. The mirror dislocated and falls off and cannot be adjusted per driver viewing needs. There is a defective assembly and it inhibits driver view causing hazardous conditions that could cause accidents. | Crash: No Fire: No | Unknown |
| Nov 2023 | VISIBILITY/WIPER | The interior rear view mirror falls off. Dealership is not fixing the problem after 4 visits. This creates a safety issue because the driver cannot view traffic that is behind the vehicle while driving in traffic | Crash: No Fire: No | Unknown |
| Nov 2023 | ELECTRICAL SYSTEM | Upon going to start my vehicle it would not start. I ended up jump starting the car and going to buy a new battery. I replaced the battery even though repair facility stated battery was at 78% and in good state. Two days later I went to start the van again and the battery was again dead. I jumped the car to get it started and have had to continually jump start the car due to no start issue. The alternator is showing a constant 14.3 volt charge when running but the battery continues to die. Has left my family stranded multiple times in the past week. No known cause or fix. | Crash: No Fire: No | Unknown |
| Oct 2023 | UNKNOWN OR OTHER | The rear view mirror on the windshield After I had the service work done for the recall, The rear view mirror on the windshield keeps breaking and hanging down. This causes hazardous conditions while driving. I took the vehicle for an oil change, and to correct the recall problem. The mirror fell apart and hung from the windshield shortly after that. The shop has confirmed that this is the part they worked on for the recall. Bisbee Honda of Danville, VA, has attempted to fix the problem 3 times. They have only been able to “stick it back together”. It causes a safety hazard as it cannot be adjusted. Meanwhile, per the service department, they initially ordered the wrong part, and failed to call me when it arrived. The (hopefully) correct part is now in backorder and per the service manager, it could be days, weeks or months. I guess it’s stuck back up with super glue or Velcro and I’ve been advised not to touch it… | Crash: No Fire: No | Unknown |
