ELECTRICAL SYSTEM, STRUCTURE:BODY
Water is leaking through back tailgate every time it rains. Water pools on the back floor and gets into the tailgate control unit. As a result, mold has grown on the floors and water has gotten into the power tailgate control unit causing my tailgate to stop opening and propping up (I have to manually hold the heavy door while lifting items out). This has caused electrical problems with cruise control and several lights blinking on and off my dashboard throughout the duration while driving. I have had the engine and transmission all tested and everything is working properly in that regard. The conclusion is that these electrical malfunctions are due to water damage. I have already had the control unit replaced once a year ago.

VEHICLE SPEED CONTROL
The acceleration lags or stalls after braking to almost a complete stop. The lag is anywhere from 1 to maybe 3 seconds and I’ve almost gotten into multiple accidents as the vehicle has stopped in the middle of a lane or intersection when I’m trying to turn. The Honda dealership says they have been able to duplicate the issue, but said they don’t have a fix for the problem.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS, LANE DEPARTURE: ASSIST
When I turned on the ignition to drive the vehicle, multiple warning lights came on to include failure of lane keeping assistance, forward collision avoidance, adaptive cruise control, lane departure warning, and automatic emergency braking. Additionally, after acknowledging these lights, the "brake system" light remained on in the amber color. If these safety features are not working properly, it can put the occupants of my vehicle as well as others at risk.

ELECTRICAL SYSTEM, ENGINE, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
When accelerating from a stop position while pushing on the accelerator the vehicle will not move. Takes a couple seconds. Almost struck by oncoming car when attempting to turn left onto Main road. Happens frequently. Next: left sliding passenger door doesn’t close all the way then opens back up. Takes several attempts before it decides to close or with my assistance. Third: rear cargo door shuts without me pushing the button. Alarm sounds and immediately shuts. Been hit in the head once while closing. I’ve seen complaints about this and Honda is apparently aware. Last; the car will inadvertently emergency brake when an oncoming vehicle approaches from the front. Very disturbing when traveling at any speed going into an instant stoppage.

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.

VEHICLE SPEED CONTROL, SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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.

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.

AIR BAGS, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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)

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM, ENGINE
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!

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.

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.

ELECTRICAL SYSTEM, LANE DEPARTURE: WARNING, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
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.
