| Aug 2025 | SUSPENSION | Premature failure of rear shock absorbers due to rust, leaking. Unpainted upper portion of shocks rusts out. | Crash: No Fire: No | Unknown |
| Aug 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | I In August 2025, I experienced a sudden and complete failure of the forward-facing windshield camera in my 2018 Honda Odyssey, which disabled multiple safety-critical systems. After having new tires installed at Discount Tire in preparation for a road trip, I started my vehicle and was immediately confronted with multiple dashboard warnings, including: •“Road Mitigation System Problem” •“Auto High-Beam Problem” •“Adaptive Cruise Control Problem” •“Lane Keeping Assist Problem” •“Brake System” I took the vehicle to a Honda dealership. They diagnosed DTC U3000:49 — Internal failure with multipurpose camera unit and informed me the only repair option is to replace the camera and perform camera aiming. The quoted repair cost is approximately $2,000. The dealer explained that this failure is “common in hot climates.” If true, this represents a serious design flaw. The Odyssey was marketed as a family vehicle equipped with advanced safety systems, yet a single component failure suddenly disables nearly every major driver-assist safety feature. This is a serious safety defect for several reasons: 1.Safety systems suddenly fail without warning. One moment the systems are working, and the next they are completely disabled. A driver relying on lane keeping, collision mitigation, or adaptive cruise control would be placed at immediate risk. 2.Known widespread issue. The dealer admitted this happens in hot climates, suggesting Honda is aware of the problem but has not addressed it. 3.Unreasonable repair cost. A vital safety component should not have a built-in failure mode tied to environmental conditions, forcing owners to pay thousands out of pocket for safety-critical repairs. 4.Loss of federally encouraged safety features. Forward collision mitigation and lane departure warning systems are strongly promoted by NHTSA itself. Their failure removes protections drivers expect when purchasing the vehicle. This issue appears to be a common defect in Honda Odyssey vehicle | Crash: No Fire: No | Unknown |
| Aug 2025 | POWER TRAIN,ENGINE | Engine has been running very rough the last 20k miles, and East Coast Honda in Surfside Beach, SC noted engine bearing wear prior to the rough engine performance during a service visit in May 2023. In June-July 2025 driving on [XXX] driving between Washington D.C. and Surfside Beach, SC, we went to pass and the engine cut RPM's drastically and went into 'limp mode' nearly causing an accident with the sudden decrease in speed. We have asked American Honda Customer Service [800-999-1009] to provide an engine evaluation but they have declined and have stated our VIN is not included in the rod bearing recall/TSB. We did mentioned about the further investigation for 2018 Honda Odyssey's but was advised any action we take would not be compensated since the vehicle is out of warranty by date and mileage (73,000 miles).

| Aug 2025 | ENGINE | While driving vehicle, check engine light began to flash. Vehicle was moved safely to side of road and turn off. Vehicle was allowed to sit for more then five minutes and started again. no check engine light or other indicators were illuminated. Vehicle was driven another 60 miles when suddenly multiple warnings appeared with a solid check engine light. Vehicle was moved to a safe location and parked. Vehicle was transported to a Honda dealership the following day and was discovered to have metal in the engine oil due to connecting rod bearing failures with grooves worn in the crankshaft. | Crash: No Fire: No | Unknown |
| Aug 2025 | POWER TRAIN,VEHICLE SPEED CONTROL,ENGINE | Vehicle has a vibrating shake when you go about 26 to 40 miles per hour like it does not know on what gear to be me I took the car multiple times to the dealership, and after charging me hundreds of dollars they had the face to say it is what it is. That the design of the car. I even called the corporate and no one really cared. I am always scarred that engine or transmission will fail and cause an accident. On the last trip, as I was stuck in traffic, stop and go was hard on this condition as car wants to think on what gear to be. | Crash: No Fire: No | Unknown |
| Aug 2025 | ENGINE | Several people have told me that they hear a banging or thudding heavy sound coming my 2018 odyssey engine. The sound frequency increases as the engine rpm’s increase. I have seen many reports that state that this symptom could lead to a total engine failure which makes the car unsafe and is caused by incorrectly machined crank shafts (oversized). I called Honda and was told there is no recall at the time ( 8/23/25). In my opinion there should be a recalled. There was not warnings presented. Another failure occurred when mice ate the fuel injector wiring. This caused the engine to malfunction . The cause of this failure I have been told was caused by Honda using wire with a soy based insulation which mice eat. | Crash: No Fire: No | Unknown |
| 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.

| 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 | 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 | 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 | 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 | 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 | 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 | 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 | 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 | 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 |
