| Aug 2025 | ENGINE | There is a recall on this engine, same year, same make and model, but not my VIN number, same problem as the recall. Honda NHTSA campaign 23V751000 On [XXX] my husband and I were driving from our home in Scottsdale, AZ to Las Vegas, NV. About one hour from Las Vegas a yellow light came on the dash. I immediately pulled off the highway and looked up what the light meant. The manual said to continue to nearest service location and add oil. I restarted the car and there was a very loud clanking sound and a warning of Emissions System Failure came on. I turned the engine off, called AAA and had the vehicle towed to AAA Las Vegas. In the late afternoon of [XXX] they advised us that the car needed a new engine. Also troubling is that Right Honda did not fully evaluate the engine, but charged $180. They relied on the AAA report and wanted to sell me a used engine, one year warranty, but could not tell me about the engine, other than mileage because it "was on a pallet." 1. Report from AAA 2. Right Honda Estimate for USED ENGINE 3, E-mail from Right Honda stating they could not tell me about the engine 4. E-mail from Right Honda stating they would not diagnose because it was too much work INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) | Crash: No Fire: No | Unknown |
| Aug 2025 | ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE | In our 2018 Honda Odyssey EX-L, a few weeks ago 5 different warning lights started coming on when the vehicle was started and continued while the car was driven. Lane Assist, collision warning, auto high beams, braking system and adaptive cruise control. Just yesterday the rear hatch started to malfunction; currently the rear hatch can be opened and closed manually but the power lift does not function and now is the 6th warning on the driving display. The car was taken to a Honda Dealership for diagnosis, and after paying $99 for the diagnosis of the issues, several other diagnosis fees would be required to get to the root of the issue which the Tech states is most likely a control module malfunction due to a water leak. The fix would then be finding and fixing the leak, then replacing the module and wrapping the module in plastic to prevent future issues. Then more diagnosis fees to find and correct the other issues which could include replacing the multipurpose camera. -If a selling point of the driver assist, collision warning and automatic braking are safety improvements, by default if the system is faulty then ours and others safety is at an increased risk. -the vehicle has been inspected by a dealer -before a few weeks ago no warning lamps, messages or other symptoms were present. All of the symptoms have been rather sudden. We have been getting rain almost daily for the past few weeks. | Crash: No Fire: No | Unknown |
| Aug 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | the adaptive cruise control, collision warning, lane keep assist and other safety features have stopped working as indicated by errors displayed on dashboard. Suspect front camera is malfunctioning but has not been confirmed by independent service center. At first, this seemed to be an intermittent issue, but now the error messages appear every time the car is used. | Crash: No Fire: No | Unknown |
| Aug 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | Brake system light, and other warning lights including Adaptive cruise control, lane keeping assist, collision mitigation, road departure warning, and auto high beams: A common issue from internet which likely be caused by the camera/sensor issue (near the rearview mirror) | Crash: No Fire: No | Unknown |
| Aug 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE,BACK OVER PREVENTION | The windshield-mounted front camera assembly (part number 36160‑THR‑A81) that powers LKAS, ACC, Collision Mitigation, Auto High Beam, and other safety systems has failed on my 2018 Honda Odyssey. When the camera fails, multiple critical safety systems become disabled at once, posing a significant risk to driver and road safety." Supporting Evidence from Other Owners: Honda Odyssey owner posted in a parts-related forum: > “The Honda garage wants $1.5K to replace the front camera, but I’m wondering why it catastrophically failed after 3.5 years and 30,000 miles!” A documented complaint filed with NHTSA highlights a very similar situation: > “All Honda sensing technology is not working… ACC, LKAS, Collision Mitigation, Auto High Beam… many warning lights appear on the dash… diagnostics… indicated the issue may be related to a manufacturer defect… dealership… said the monocular camera was defective… The contact… replaced the defective monocular camera, … once the repair occurred, all of the messages and lights… cleared and all of the safety systems… are now working correctly.” Costs: Owners have reported paying approximately $750 for the camera part and another $500 for calibration, totaling around $1,250. We have even been quoted $2,500 to replace the front camera. Safety Risk: The failure disables multiple driver-assistive safety systems simultaneously, increasing risk of collision — especially since these systems (ACC, LKAS, Collision Mitigation) are intended to help prevent accidents. Conclusion / Call for Action: Given the frequency of similar reports, recurring nature of the front camera failure (36160‑THR‑A81) in 2018–2019 Odyssey models, the high cost of repair, and the safety-critical systems that fail when this component fails, I believe this qualifies as a design or manufacturing defect. I respectfully request that NHTSA investigate this issue and consider issuing a recall for affected vehicles. | Crash: No Fire: No | Unknown |
| Aug 2025 | POWER TRAIN | The transmission is very jerky and has completely lost power before. It has refused to shift and stalled in the middle of the road. It is very scary. | Crash: No Fire: No | Unknown |
| Aug 2025 | LANE DEPARTURE,FORWARD COLLISION AVOIDANCE | 1. Vehicle Information Year / Make / Model: 2018 Honda Odyssey Touring Mileage at Time of Incident: Approximately 123,952 miles Purchased New or Used: Used 2. Incident Summary On June 13, 2025 upon starting the vehicle for the first time that day (vehicle is garage kept, year round, at home when not in use), problem codes for the Auto High Beam, Adaptive Cruise Control (ACC), Lane Keeping Assist System (LKAS), Collision Mitigation Braking System (CMBS), and Road Departure Mitigation (RDM) showed on the display and all features failed to function. 3. Detailed Description of Failure & Safety Risk (Chronological) Component/System Affected: I have not taken the vehicle to the local Honda dealership as yet as I plan to schedule an appointment during the week of 17 August. After researching this issues it is found that many other consumers have experienced the same issue and confirmed that it was the ADAS front-facing camera and radar sensor failure. Due to the failure this causes the following safety systems to cease functionality: Auto High Beam, ACC, LKAS, CMBS, and RDM. Vehicle is available for inspection upon request. Safety Risk: All affected systems are critical for maintaining lane position, speed, collision avoidance, and visibility. Not having these critical safety features creates a heightened risk of collision or unsafe maneuver. Inspection: Only an authorized Honda dealer will inspect/diagnose the issue. There has been no inspection from the vehicle manufacturer, law enforcement, insurance, or independent service. | Crash: No Fire: No | Unknown |
| Aug 2025 | UNKNOWN OR OTHER,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | My car have never in an any accident but my distance radar sensor not working. And it’s very risky to drive under this condition and it’s very big safety for me and my life so help me to fix this issue. | Crash: No Fire: No | Unknown |
| Aug 2025 | SUSPENSION | A safety-related part, the rear coil spring (PN 52441-THR-A01 / 52441-THR-A11), is not available through Honda’s parts network. Without this part, my vehicle’s safe operation is compromised. | Crash: No Fire: No | Unknown |
| Aug 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | 5 Major safety systems are automatically disabled and on further troubleshooting by the dealer, all these issues are pointing to a faulty Front Collision Avoidance Camera. The cost to replace and recalibrate the camera is upwards of $2400. This is absolutely ridiculous and seems like a safety recall issue. | Crash: No Fire: No | Unknown |
| Aug 2025 | SUSPENSION | 2018 to 2024 Honda oddessy rear shocks top rusts prematurely through the metal and leaks out the oil making the shock useless. my 2018 Honda Odyssey with 70k miles rear shocks suddenly broke and top is rusted through the metal and is leaking fluid. Honda factory part number 52610-THR-A02 is forbthe rear shocls common problem with 2018 -2024 Honda odessy with 50k to 80k miles so iust after the dealer factory warrenty runs out. metal housing on a shock is not supposed to rust through with 7 years of use. | Crash: No Fire: No | Unknown |
| Aug 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | All of the warning lights associated with advanced safety features came on on the way back from a visit to local store. When checking the codes there is a The U3000-49 code indicating an issue with the mono camera or radar unit. These warnings do not allow for the use of any of the safety features affected. The code cannot be cleared from the system either. | Crash: No Fire: No | Unknown |
| Aug 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | The multipurpose camera failed bring down all driver assistance functionality including lane keep assist, emergency brake, auto high beam, parking sensors, cruise control, etc. fix is outrageously high $2500+. Internet search finds this to be a very common issue and deserves a recall. | Crash: No Fire: No | Unknown |
| Aug 2025 | ENGINE | While driving on the highway at speed, without warning or any dash check lights we heard a loud pop from the front of the car followed by white smoke. The engine seized, lost all power, and the along with it the brake system shutdown so the car became uncontrollable on a busy highway. The car was towed to a local honda dealership and is currently being looked at. The vehicle was recently inspected at a honda service center where there was no indication of any engine issues. There were no check engine lights untill the engine seized. | Crash: No Fire: No | Unknown |
| Aug 2025 | ELECTRICAL SYSTEM,STRUCTURE | Water intrusion, verified by observation/application of water. The leak resulted in water dripping on the Tailgate/Liftgate Control Module and the general rear cargo area, causing corrosion inside the control module rendering the control module inoperable, which made the power liftgate inoperable as well. Additionally, the rear cargo area had standing water that had accumulated over an unknown period of time that was visible when you lifted the carpeting. The liftgate latch mechanism also "locked" while the liftgate was open, making securing it closed in the normal way impossible. I would have needed to secure it with bungee cords or tape or some other haphazard way if I wanted to drive it safely on the streets or any contents in the back of the van could have fell out in traffic, or the liftgate may have inadvertently lifted at any time or place uncommanded, causing any type of hazard. Replacing the Control Module ($331.53) remedied the liftgate failure. However, the leak remains, and will allow the same thing to continue to happen. Applying water to the area where the seam on the drivers side body panel and the roof panel meet resulted in water being seen dripping in the interior of the vehicle and onto the liftgate control module. This area should have been made waterproof before the vehicle left the factory, and should be recalled to make it right. | Crash: No Fire: No | Unknown |
| Aug 2025 | ELECTRICAL SYSTEM | The vehicle body weather seal did not function water was leaked into the rear trunk of the vehicle, resulting in water damaged carpet/ foam and malfunctioning/ broken power liftgate control module for the rear hatch. The control module was found to be corroded resulting in a nonfunctional rear hatch. | Crash: No Fire: No | Unknown |
| Aug 2025 | SUSPENSION | The driver side coil spring broke on the lower end of the spring. It started to sound squeeky after a change in the road or a bump. 2 years ago, the right (passengers) coil spring broke in the middle of the spring on a main highway going 60miles/hr in another state from where we live. The car needed towed then and replaced. I filed a report with you then. No one was hurt either time but could have been. The springs have been on back order....2 years ago we couldn't get a replacement because they were on back order for 2 years then and needed to get a backup from a juck yard to replace. This time we still can not find a replacement in stock and are afraid the springs are not strong enough for the honda cars which is why they have been on backup and keep failing. So now they have been on back order for 4 years. My husband's car has springs bigger than what they put on the minivan. And with the part on backorder still...I don't think they are good or that Honda wants to replace them. We had to get springs from somewhere else to replace this spring....causing us to pay for 2 new ones to put on the car. Car is currently in the shop (auto shop) waiting for the parts to arrive from another state to replace. These should definately be recalled! I don not have a heavy family or put heavy stuff in my vehicle but someone is going to get hurt soon. Honda needs to take care of this safety problem and reimburse for all the coil spring problems. | Crash: No Fire: No | Unknown |

| Jul 2025 | ENGINE | We do not own the vehicle anymore, but I just learned of recalls for this issue and wanted to make sure I submitted this as our lives were significantly affected. In July 2023, on the way home from a trip, we began to hear knocking in the engine and shortly after the check engine light began flashing. We got to the closest mechanic, and they suspected an issue with rods due to metal filings in oil. We had it towed 2 hrs to the closet Honda dealership. Garcia Honda in Albuquerque, NM. After days in a hotel and the dealership making the repairs they thought it was, we were told it was ready to go, they just needed to do a test drive. On the test drive, the engine lights come on again, and on closer inspection, they too heard knocking, and diagnosed engine failure due to rod issues and told us we needed a full engine replacement. We were still 9 hours from home and had missed work for a few days, and being dejected and overwhelmed that we still did not have our car to get home, we made the snap decision to purchase a new car there and “trade in” the odyssey for the bare minimum. We mentioned to someone today that we had a Honda with engine failure, and they brought this recall to our attention. After researching, I wanted to make sure to get this complaint failed, to hopefully help others going through what we did. | Crash: No Fire: No | Unknown |
| Jul 2025 | POWER TRAIN,ENGINE | Rod knock diagnosed and confirmed by dealership July 15, 2025. Van is currently at dealership and is available for inspection. I have paused work to allow Honda (case 15705425) and now this team the opportunity to diagnose and inspect first hand. Inspection and first hand visuals have only been completed by certified Honda dealerships. All warnings and my concerns are documented in our ROs with Honda dealerships. When any light or reminder came on, I immediately took the van to Honda for service. Safety: slow starts and sluggish acceleration. Noise that was not normal. Out to eat 30 minutes away from home July 13 and van wouldn’t start. Dealership thought initially battery but then kept van overnight and nod rock confirmed. Also repaired back suspension. Additional details: Problem has been reproduced and confirmed. Have been experiencing slow start, van not driving properly. Our family went out to lunch July 13 and van wouldn’t start. Waited handful of minutes and then started. Immediately took to dealership next day. Honda dealerships have done all servicing and repairs on this van. (I was told there are 55 repair totaling $22k for your research purposes.) Honda notified me July 29, 2025 that they will NOT offer any assistance and/or goodwill because of the age and mileage of the van. Escalating case 15705425 up Honda chain - we have been very loyal to Honda. As of today, July 31, 2025: Van sits at dealership; has been there since July 14, 2025. I have been advised not to drive the van, esp on the highway. I want to keep the van and want to drive it for many more years. Took very good care of it and followed all of Hondas recommendations for servicing. Just put brand new tires front suspension (March 2025) and rear suspension (July 2025) on it as well. Appreciate your investigation. I’m working diligently to do the right thing and allow the proper people time to investigate the van before any work begins on the engine. | Crash: No Fire: No | Unknown |
| Jul 2025 | POWER TRAIN | The contact owns a 2018 Honda Odyssey. The contact stated that while depressing the accelerator pedal, the vehicle failed to respond as intended. The contact stated that the failure has caused the vehicle to hesitate while attempting to accelerate. The contact stated that the failure had occurred on several occasions while driving on the interstate and the freeway. A dealer was contacted. The vehicle was taken to the dealer, where it was diagnosed, and determined that the software needed to be updated and the vehicle needed to be driven approximately five thousand miles to correct the failure. The vehicle was repaired, and the transmission was replaced once before. The manufacturer was notified of the failure; however, the warranty department failed to return the call. The approximate failure mileage was 108,900. | Crash: No Fire: No | 108,900 |
| Jul 2025 | ELECTRICAL SYSTEM,LANE DEPARTURE,FORWARD COLLISION AVOIDANCE | the sensor/computer/camera on the windshield overheats and causes it to fail mines at 100,000 and its a $1600 repair dealer said because the windshield sits in sun while driving etc and the sensor overheats and melts the inside of the computer soldering. unacceptable so much for my safety features all gone i dont have the money to replace | Crash: No Fire: No | Unknown |
| Jul 2025 | LANE DEPARTURE,FORWARD COLLISION AVOIDANCE | I recently replaced a battery on the 2018 Honda Odyssey. When I turned the car on, the dashboard showed 6 issues: adaptive cruise control problem; lane keeping assist problem; collision mitigation system problem; road departure mitigation system problem; auto high beam problem; and the brake system light was on. I paid a mechanic to clear out the code and the was told that the front sensing camera needs to be replaced. Without a replacement, all these errors will continue to show up. I search online to find out if other people have had this issue because it was just too coincidental that a battery replacement broke the front camera. I found posts by many people who own the 2018 Honda Odyssey having similar or near identical issues that I have had. The cost to replace the camera and have it recalibrate it is going to cost $1,800.00 as estimated by a local Honda dealer. The Honda dealer told me that they have seen this problem over and over again. | Crash: No Fire: No | Unknown |
| Jul 2025 | FORWARD COLLISION AVOIDANCE | The front camera failed so there were 5 warnings all together: Collision mitigation system problem, Lane Keeping Assist problem, Adaptive Cruise Control problem, Auto High-beam problem, Road departure mitigation system problem + Brake system warning. They claimed the bad battery, bad wheel alignment but they were not an issue. The front camera was failed, and it costs $2,408 after their discount coupon. Same thing happened to my 2019 Honda Accord hybrid. I googled it and found a lot of Honda vehicles share same problem. All the malfunctioning come from the failed front camera and it could be very dangerous if it happened during driving. This is a serious safety issue and all Honda's fault. They provided the problematic part. I never heard the similar problems happened to other brands such as Toyota, Chevy, Hyundai, and more. All happened to Honda car. They provided the poor quality front camera and they charging fortune to replace it. That front camera costs more than 10% of my current car value. It does not make sense. I strongly claim Honda should recall their front cameras and reimburse all the expense we already paid. Thank you very much. | Crash: No Fire: No | Unknown |
