STRUCTURE:BODY
The motor on the passenger side sliding door on our 2018 Honda Odyssey failed. The door could not be opened electrically - or Mechanically from inside or outside the vehicle. We had it repaired at the dealer at a cost of ~$2,000. The sliding door was INOPERABLE when the motor failed. If the car was in an accident the door could not be opened by second or third row passengers or first responders to enable evacuation from the vehicle. This is EXTREMELY DANGEROUS! The problem was confirmed by the dealer. The sliding door can’t be opened when the motor fails. The dealer also stated that Honda had an active engineering assessment in process and that a recall might happen - so hold on to our receipt.

ENGINE, POWER TRAIN:AXLE ASSEMBLY
The contact owns a 2018 Honda Odyssey. The contact stated that while driving 60 MPH, the vehicle stalled and lost motive power with several warning lights illuminated. The contact pulled over to the side of the road, shifted the vehicle into park(P), and there was smoke coming from the engine. The vehicle failed to restart after the failure. The vehicle was towed to a service center, where an engine failure was confirmed, and the contact was referred to the dealer for assistance. The vehicle was towed to the dealer, where it was diagnosed and determined that the engine and front axle had failed and needed to be replaced. The manufacturer was made aware of the failure by telephone. The failure mileage was approximately 117,000.

LANE DEPARTURE: ASSIST, LANE DEPARTURE: WARNING, BACK OVER PREVENTION: WARNINGS
All my warning light come on every time I turn on the van. Been going on for several months. Was told the issue will get fixed if the front camera under rear view mirror get replaced. Feel like this needs to be recalled to get fixed, especially finding out Honda already knew there was a issue.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS, LANE DEPARTURE: WARNING
All this warning lights just come on out of no where due to the safety camera feature on the windshield that controls all the safety features of the car and this vehicles are not even 10 years old and the repair cost is too expensive for just that camera and almost every Honda odyssey is having the same issue I think there should be a recall for that specific camera in my opinion.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, LANE DEPARTURE: ASSIST
It started back in July 2026; I had a warning pop up that some functions aren’t available and to clean front windshield camera. We did. Still received the warning. Sometimes it’s there and sometimes it’s not. I can go down the highway and it will come up and then a few miles later it’ll turn off and the functions work. Even driving around town it does it. I have noticed there are a lot of drivers of the 2018 models having this same issue.

UNKNOWN OR OTHER, ELECTRICAL SYSTEM
On October 14/15, 2026 it rained. At approximately 12:25pm on October 15, 2026 my power lift gate stopped working. It wouldn’t open with any of the controls. Upon further inspection we noticed the control module had water damage. We replaced the module on October 21,2026. It is still having issues. It opens with the controls but won’t close using the same controls. You have to manually close it.

ELECTRICAL SYSTEM, STRUCTURE:BODY
In XXX, the power tailgate on my 2018 Honda Odyssey stopped working. I took the vehicle to authorized Honda dealer Fred Beans Honda of [XXX]. The technician documented in writing on repair order #XXX (XXX): "There is water leaking onto the power tailgate control unit. Technician found the water leak going into from the back of roof on the left side. Needs a new power tailgate control unit." Water entered through the rear body seam seals and dripped onto the power tailgate control module (P/N 74970-THR-A12). The removed module showed severe blue-green corrosion -- it does not fail on its own at 31,500 miles. Safety concern: A tailgate whose control module is destroyed by water intrusion cannot be relied on to latch or stay closed; an unlatched or unexpectedly opening tailgate while driving endangers occupants and surrounding traffic. Known defect, not isolated failure: Honda issued a TSB on rear body seam-seal water intrusion on 2018-2019 Odysseys; federal class action Case No.XXX (XXX.) covers 2018-2021 Odysseys with defective polyurethane seam seals destroying the power tailgate control module; numerous owner reports in the NHTSA database describe identical failures. What I did: The dealer quoted $1,302.88. I first asked American Honda by phone for goodwill coverage and was denied. I repaired it myself with a genuine Honda module ($215.57, Order #XXX, XXX); total out-of-pocket $416.92. On XXX I submitted a written goodwill reimbursement request online (case #XXX, continuing prior case #XXX); on XXX Honda denied it as not covered under any campaign, even though the failure is caused by the documented seam-seal defect that is the subject of the pending class action above. What I am asking NHTSA: record this complaint and consider investigation/recall of the 2018-2019 Odyssey seam-seal water intrusion defect.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, LANE DEPARTURE: WARNING
I own a 2018 Honda Odyssey Touring. On May 29, 2026, I started the engine on my Odyssey and several dashboard system warnings appeared. The internet suggested having the battery tested and it was getting low, so I replaced the battery. The warning signs remained and caused several Honda Sensing safety and driver-assistance systems to become unavailable, including Adaptive Cruise Control (ACC), Lane Keeping Assist System (LKAS), Collision Mitigation Braking System (CMBS), Road Departure Mitigation, and Auto High Beams. Additionally, a Brake System warning appears on the dashboard. I have video recording of these warnings from when they first appeared in May. On September 2, 2026, the lights disappeared out of nowhere and all components worked. Later that same date, the lights were back and the components stopped working again. This happened again on October 13, 2026 - lights went off, then returned later in the day. The recurrent temporary reprieve from the lights makes me wonder if there is an electrical short in the rearview camera that controls those safety features. The diagnostics cost of this alone was going to be nearly $200. As numerous other similar complaints have been made to NHTSA, I am hoping this issue will be investigated and addressed - it is concerning that a single system failure is causing multiple safety features to be disabled - notwithstanding that is is difficult to know when to be worried about warning lights when the dashboard is full of them.

AIR BAGS
Subject: Airbag Deployment After Recall Repair - 2018 Honda Odyssey My 2018 Honda Odyssey received the Honda airbag recall repair in XXX. After the recall remedy was completed, the driver's side by side curtain airbags deployed unexpectedly while I was driving. At the time of the incident, I struck a curb at approximately 25-30 mph. However, there was no collision involving another vehicle, object, or side-impact event, and there was no contact with the vehicle's bumper or body. The tire was not damaged. Fortunately, I was the sole occupant of the vehicle, and no children were present. Despite the absence of what I believe would be a qualifying side-impact collision, the driver's side curtain and side airbags deployed. I am reporting this incident because it occurred after the manufacturer's recall repair had already been performed. I will also provide the inspection report from Firestone, which indicates that the front passenger-side wheel alignment was affected as a result of the curb impact. I respectfully request that Honda investigate this incident, review any available SRS (airbag system) diagnostic data, and determine whether the airbag deployment was related to the previously recalled condition or another defect. Please advise if any additional information or documentation is needed. Thank you for your attention to this matter. Sincerely, [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, LANE DEPARTURE: ASSIST, LANE DEPARTURE: WARNING
there is a very common issue with Hondas that the front camera behind the rear view mirror shuts down which causes many safety systems to shut down and nit work this happened to my car it is very unsafe as i am now missing five very important safety features and i am going to have to pay thousands to repair it. This problem has been confirmed by my mechanic as he inspected it. This happened randomly out of nowhere with no signs of this coming. The five components that do not work because of this camera failure are lane assist, auto high beam, lane departure, adaptive cruise control, and collision warning. This puts me and others at danger.

ENGINE, FUEL/PROPULSION SYSTEM
The vehicle was stalled on highway local about seven times. My car got stranded and almost got into serious accidents. This happened multiple times and Honda couldn’t fix it. I spent $9000 and couldn’t find the problem. Honda changed fuel injectors, pump, regulator, high pressure. But the car is still stranded on highway which is very dangerous

FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, LANE DEPARTURE: WARNING
Camera/Radar behind the rearview mirror failed. This triggered the following alerts to populate. Forward collision alert, auto high beams, lane departure, active cruise control (active and passive both failed to work), brake system, transmission system, lane keep assist failure. The gear indicator would flash when the transmission system error came on. Van has ~76k miles on it. ~$119 for diagnosis, ~$1400 for the part, ~$300 for the calibration and several additional hundred in labor. This is a known issue with the 5th generation Honda Odysseys. Honda won't do anything about it. It was up to 8 error messages on the dash at one point.

FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, LANE DEPARTURE: WARNING
I own a 2018 Honda Odyssey Elite. On October 5, 2026, at 120,007 miles, an authorized Honda dealership diagnosed the vehicle with DTC U3000-49, Multipurpose Camera Internal Failure. The Honda technician cleared the DTC, but it returned shortly afterward. The technician inspected the camera and connector for poor connections or damage and documented that none were found. The dealership determined that the multipurpose camera needs to be replaced and reprogrammed. I was quoted $2,350 plus tax for the repair. The failure causes multiple Honda Sensing safety and driver-assistance systems to become unavailable and produces multiple dashboard warnings, including Adaptive Cruise Control (ACC), Lane Keeping Assist System (LKAS), Collision Mitigation Braking System (CMBS), Road Departure Mitigation, and related safety-system warnings. I have video documenting these warnings following the dealership diagnosis. My safety concern is that an internal failure of a single multipurpose camera can simultaneously disable multiple collision-avoidance, lane-assistance, and driver-assistance systems. I am reporting this failure so NHTSA has a record of the U3000-49 failure on my 2018 Honda Odyssey and can determine whether this represents a broader safety defect affecting these vehicles. The vehicle has not yet been repaired.
