| Apr 2026 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | ADAS camera malfunction causing all driver assist functions to not work | Crash: No Fire: No | Unknown |
| Apr 2026 | UNKNOWN OR OTHER | This has been an ongoing issue with the sensors on the sliding door. When closing the door, it would start to close half way, then opens. This makes it really unsafe for children or anyone sitting next to the door as it would open unexpectedly or not close all the way without having to physically pull the door to close. When walking away from the vehicle, sometimes the car would lock automatically (as it should) but there are also times where the door would automatically open when walking away and things has been stolen from the vehicle because of it. The sensors on these sliding doors has been a real safety issue. | Crash: No Fire: No | Unknown |
| Apr 2026 | VEHICLE SPEED CONTROL,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | My car has started breaking randomly without reason. Just a few days ago it slammed on the brakes. I was driving on the interstate and went around a bend, and my car slammed on the breaks. I. Talking from 70- 5mph in seconds. I didn't have time to do anything. Nothing in front of me, nothing on the side. The car behind me had to swerve into the median to avoid hitting me. My car almost caused an accident. Im honestly afraid to drive it. Im not sure if the radar system is an issue in other Hondas, but if i was in an accident it would have been my fault. If the person behind me wasn't paying attention my children could have been seriously injured or worse. Please look into this issue. Its more dangerous than the other recalls. | Crash: No Fire: No | Unknown |
| Apr 2026 | ENGINE | My 2018 Honda Odyssey began exhibiting intermittent acceleration lag several years before the repair, and the condition progressively worsened. At the time of repair, the vehicle had 68,957 miles. The safety concern occurs when accelerating from a stop, such as at a red light, stop sign, or when merging into traffic. I depress the accelerator normally and the vehicle does not respond. There is a delay where the engine and transmission fail to engage, leaving the vehicle stationary while surrounding traffic begins to move. To compensate, I must press the accelerator further. When the vehicle finally responds, it does so abruptly, causing a sudden surge of acceleration. This creates two safety hazards: (1) loss of control due to the unexpected “kick” when power finally engages, and (2) increased risk of collision when attempting to merge or cross traffic, because the vehicle does not accelerate when expected. I have been honked at by other drivers and have experienced near‑miss situations because the vehicle failed to move when it should have. Owner forums show many similar reports from other ~2018 Odyssey owners describing the same acceleration lag and abrupt engagement. Based on these reports, the commonly recommended fix is a throttle body cleaning and a transmission “teach‑in” procedure. An authorized Honda dealership performed these procedures on my vehicle at my expense (approximately $500–$550). These procedures are not listed in Honda’s factory maintenance schedule, yet appear necessary to correct a drivability issue that presents a safety risk. Given the frequency of similar owner reports and the safety implications of delayed or unpredictable acceleration, this issue may indicate a design or calibration defect in the throttle body, engine air‑management system, or transmission control logic. | Crash: No Fire: No | Unknown |
| Apr 2026 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | monocular camera code set and several dash messages - failure of ACC, FCW, LKA | Crash: No Fire: No | Unknown |
| Apr 2026 | ENGINE | The contact owns a 2018 Honda Odyssey. While driving at an undisclosed speed, there was an abnormal ticking sound coming from the vehicle. The accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. In addition, the contact became aware that there was smoke coming from the exhaust. No warning lights were illuminated. The vehicle was taken to the dealer where it was diagnosed with a loose rod bearing. The contact was informed that the engine needed to be replaced or rebuilt. The vehicle was not repaired. The contact referenced an unknown recall with a similar failure; however, the VIN was not associated with the recall. The manufacturer was not made aware of the failure. The failure mileage was approximately 172,750. | Crash: No Fire: No | 172,750 |
| Apr 2026 | AIR BAGS,FORWARD COLLISION AVOIDANCE | On April 20, 2026, at approximately 12:00 pm. I was driving my 2018 Honda Odyssey (VIN [XXX] ) southbound on [XXX] , approximately 3 miles north of the junction of [XXX] and [XXX] . I was traveling at approximately 30 mph. The vehicle struck a pothole in the road. Immediately upon impact, the passenger-side curtain airbag deployed with a loud report that I described as sounding like a gunshot next to my right ear. There was no collision with another vehicle or object, and no warning of any kind preceded the deployment. I was startled by the sudden deployment and noise, and the vehicle briefly swerved before I regained control. The deployed passenger-side curtain airbag completely obstructed my visibility through the passenger-side and right-rear windows. The road at that location runs along a narrow embankment with no shoulder, so I was unable to safely pull over. I had to continue driving approximately 3 to 4 miles with severely compromised visibility until I reached a safe location to park near the 9W and 340 junction. I was the sole occupant at the time of the incident. The curtain airbag deployed directly adjacent to my child’s car seat, which was installed in the rear passenger-side seat. My child was not in the vehicle at the time. Given the force and location of the deployment, a child seated in that position could have been seriously injured. Following the deployment, I experienced ringing in my right ear and ear pain that persisted for several hours. I was also significantly shaken by the incident. Component that failed: Supplemental Restraint System (SRS) Electronic Control Unit (ECU), which caused inadvertent deployment of the passenger-side curtain airbag. The vehicle and deployed airbag are available for inspection. Safety risk: The inadvertent deployment created multiple safety hazards. First, the deployment itself startled me and caused the vehicle to swerve at 30 mph on INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) | Crash: No Fire: No | Unknown |
| Apr 2026 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | Paid $210 for Honda to run a diagnostic to tell me my multi purpose camera has a failure. This has caused 11 error lights to be displayed. | Crash: No Fire: No | Unknown |
| Apr 2026 | ELECTRICAL SYSTEM,ENGINE,FUEL/PROPULSION SYSTEM | Multiple times of driving the vehicle as I am trying to press the gas pedal while driving it acts like it is not working and suddenly it stutters and stalls. The car will shut off and put you into to neutral while you try and pull over to the side of the road without being hit. It happens randomly and without rhyme or reason. After it shuts off codes are thrown such as brake failure, emissions failure, hill assist failure, steering failure, and lane assist failure. The car will be really hard to restart and if eventually will and then everything will disappear and go back to normal. Codes leave and car drives fine until it messes up again. First time it happened was months ago from this report, and then it happened monthly, weekly and now almost daily but only when you try and drive. Very unsafe and there’s no reason cars should stall at high speeds going down interstates! | Crash: No Fire: No | Unknown |
| Apr 2026 | ENGINE | Noise coming from engine. No engine light nor warnings otherwise. Van was taken to dealership where it was confirmed that a rod bearing inside the engine assembly is faulty, which could cause sudden stalling of the vehicle, even while traveling at high speeds on the highway. This is a known issue (Honda Service Bulletin 24-003) with this model van manufactured at the same time, for which a national recall notice was issued. However, my vehicle’s vin was not included in the recall. | Crash: No Fire: No | Unknown |
| Apr 2026 | AIR BAGS,UNKNOWN OR OTHER | In the afternoon hours of [XXX]; my wife, 2 children and I were traveling away from Pageland, SC on [XXX] . My wife was driving the vehicle and hit a pothole on right side of our lane. This caused both driver and passenger side curtain airbags to deploy. Upon exiting the vehicle no visible damage was found other than a leaky passenger side front tire. This incident jeopardized the safety of everyone in our vehicle due to the powder or smoke that comes out causing a visual obstruction of the road, and the sudden unexpected deployment that scared my wife at the exit of a curve. Thankfully, she kept control of the vehicle and did not collide or wreck in to anything. I still called for the North Carolina Highway Patrol due to the incident that happened. The Trooper explained to us that he could not do a wreck report because, there was no collision. He did however do something different and provided us with a copy of it. Due to this, the insurance company totaled the vehicle and forced us to find a different vehicle. I am unsure if this vehicle was inspected afterwards by anyone other than the insurance company. Prior to this incident there were no warning lights or messages stating there was a problem. After the incident, several messages popped on the screen referencing several safety systems on the vehicle and the tire pressure system on the passenger side front tire.

| Apr 2026 | ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | In May 2025, the front-facing windshield-mounted monocular multi-purpose camera unit abruptly failed in our 2018 Honda Odyssey Elite. The vehicle had ~53,000 miles on the odometer at the time. This resulted in essentially all of the warning lights showing/cycling on the dashboard display and total failure of the safety features dependent on this camera system (adaptive cruise control, forward collision warning, automatic emergency, lane departure warning, lane keeping assistance, etc). The unit had to be completely replaced and calibrated by my local Honda dealer. | Crash: No Fire: No | Unknown |
| Apr 2026 | LATCHES/LOCKS/LINKAGES | The contact owns a 2018 Honda Odyssey. The contact stated that while driving at various speeds, the message "Right Sliding Door Failure" was displayed. The contact was forced to pull over and manually close the door for the door to latch securely. The failure returned after the contact resumed normal driving. The contact stated that a message in red stating "Stop Immediately" and another message "Right Sliding Door Failure" was displayed while driving at highway speeds. The vehicle was taken to the dealer where the contact was provided estimates for a diagnostic test and the repair. The contact was referred to the NHTSA Hotline by the dealer to report the failure. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 134,000. | Crash: No Fire: No | 134,000 |

| Apr 2026 | ELECTRICAL SYSTEM | The contact owns a 2018 Honda Odyssey. The contact stated that while attempting to start the vehicle, several unknown warning lights illuminated. An independent mechanic was contacted. The vehicle was taken to the independent mechanic where it was diagnosed and determined that the windshield camera sensor had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 60,000. | Crash: No Fire: No | 60,000 |
| Apr 2026 | POWER TRAIN,ENGINE,FUEL/PROPULSION SYSTEM | Our 2018 Honda Odyssey repeatedly and without warning completely loses acceleration power, creating extremely dangerous driving conditions. This occurs in two distinct situations:(1)while driving at highway speeds when attempting to change lanes or accelerate, and(2)when stopped at a stop sign or intersection and pressing the gas to merge into or turn into traffic. In both situations, pressing the accelerator results in little to no response — the vehicle will roll but fails to accelerate as needed. These failures have placed our family in multiple life-threatening situations. On Interstate 285 in Atlanta, Georgia — one of the busiest and highest-speed highways in the country — our vehicle has failed to accelerate during lane changes on multiple occasions, nearly causing serious accidents. Most recently, within the past week, my husband was driving on I-285 when he pressed the accelerator and the vehicle had absolutely zero acceleration response. He narrowly avoided a collision. We have also experienced complete loss of acceleration when turning from a stop sign into traffic and when merging — situations where immediate acceleration is critical to safety. The vehicle lags for several seconds before any power is delivered to the wheels, leaving us dangerously exposed in oncoming traffic. All manufacturer recalls have been completed, including the fuel pump recall. The problem persists and has not been resolved by any dealer service or recall repair performed to date. We are aware that this is a known, widespread defect affecting 2018 Honda Odysseys equipped with the ZF 9-speed automatic transmission. Hundreds of other owners have reported identical symptoms to NHTSA and to Honda directly. Honda has acknowledged the transmission's behavior to some owners but has stated it is "how the car is supposed to drive" — a response that is wholly unacceptable given the documented near-accidents this defect is causing.We are requesting that NHTSA open or expand its investigation | Crash: No Fire: No | Unknown |
| Apr 2026 | POWER TRAIN,VEHICLE SPEED CONTROL | When driving the transmission is slipping meaning it jerks forward when accelerating on the road. | Crash: No Fire: No | Unknown |
| Apr 2026 | STEERING,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | While driving on a clear road, with or without heavy traffic, the collision mitigation warning shows up on the dashboard display. Sometimes the warning for the collision system goes off and the system tries to brake and jerk the wheel. If I have the wheel firmly I can correct it and it resolves. It can happen on a clear road with no one around or in heavy traffic. Yesterday it happened in a single lane with barriers on both sides, a road around Logan Airport in Boston, with no vehicles ahead of me. The car tried to steer me into the barrier. I was doing less than 25 MPH. The warning had been going off for a while but now that the steering and braking are involved it’s much more serious. I reported it to the dealer. They said they did a system check and couldn’t find a fault. The braking and steering problem first occurred about a month ago. The warning by itself has been happening intermittently for over a year. This happens even when the collision mitigation system is turned OFF. This is a terribly unsafe issue. If my wife had been driving I don’t know if she could have corrected. PLEASE ACT AND ISSUE A RECALL! | Crash: No Fire: No | Unknown |
| Apr 2026 | POWER TRAIN | I am reporting a dangerous and recurring transmission defect in my 2018 Honda Odyssey equipped with the ZF 9-speed automatic transmission. The vehicle experiences sudden and unpredictable delayed acceleration, particularly at low speeds. When attempting to accelerate from a complete stop or at speeds below 25 mph, the transmission fails to engage properly, leaving the vehicle stranded in the middle of traffic with no power response for several seconds. This creates an extreme safety hazard, as other vehicles may collide with mine while I wait for the transmission to respond. The condition is intermittent and unpredictable, making it impossible to anticipate when it will occur. It happens most frequently when accelerating from intersections, merging into traffic, or navigating through slow-moving areas. Honda has acknowledged this defect through TSB 19-124 (issued December 2019), which addresses harsh and jerky upshifts in 2018–2019 Odysseys with the 9-speed transmission. However, the TSB does not fully resolve the issue. A class action lawsuit [XXX] et al. v. American Honda Motor Co., Case No. 5:23-cv-05011-BLF, N.D. [XXX] ) is currently pending for this exact defect. I am requesting that NHTSA open a formal investigation and consider issuing a safety recall, as the delayed acceleration constitutes a serious risk of collision and injury.

| Mar 2026 | FORWARD COLLISION AVOIDANCE | our honda odyssey 2018 elite - has a failed windshield monocular camera - original part (36160 - THR - A73) failure is a u3000-49 error. This failure causes most of the advanced safety features of the vehicle to not be operational. see these dashboard errors: Collision Mitigation System Problem Road Departure Mitigation System Problem Auto High Beam Problem Adaptive Cruise Control Problem Current repair cost from a dealership can exceed $2000. I've researched many forums and this seems to be a very common problem among Honda Odysseys of similar year range. I fee like Honda should issue a recall and replacement for owners since this involves many of the saftey features of the vehicle and cost is very prohibitive to fix for many of us. | Crash: No Fire: No | Unknown |
| Mar 2026 | ELECTRICAL SYSTEM,STRUCTURE | The roof leaks in the LH rear of the van under the roof strip thru a bolt or bad seam rfom a bad build causing the Power Unit Liftgate Module PN - 74970-THR-A11 to get wet and sit in water causing a short to the battery, The sliding doors to fail and the rear liftgate to fail which is a safety hazard if someone cannot exit the vehicle in an emergency. It is also a fire potential. This should be a safety recall at Hondas expense. The world wide web is flooded with videos and forums pertaining to this exact issue and Honda has not stepped up to the plate and addressed this issue. | Crash: No Fire: No | Unknown |

| Mar 2026 | UNKNOWN OR OTHER | I am writing to formally report an issue with my 2018 Honda Odyssey. I recently discovered water seepage in the rear trunk area, which has caused moisture buildup and potential interior damage. After researching the issue online, I learned that many other 2018 Odyssey owners have reported the same water‑leak problem, indicating that this may be a known manufacturing or design defect. Despite similar complaints, I have not seen any acknowledgement, recall, or official response from Honda addressing this issue. As a long-time Honda customer, I am disappointed that such a significant problem—one that can lead to corrosion, mold, and electrical complications—has not been proactively addressed. I am requesting: An inspection and repair at no cost, as this appears to be a widespread defect. Clarification on whether Honda is investigating or planning to address this known issue. Assurance that any related damage caused by the water seepage will also be covered. I take pride in maintaining my vehicle, and I expect a reliable, defect-free experience from a brand like Honda. I hope Honda will take this matter seriously and provide a prompt resolution | Crash: No Fire: No | Unknown |
