FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, VEHICLE SPEED CONTROL, LANE DEPARTURE: ASSIST
Over the course of 3 days, cruise control and lane assist systems would shut off and messages would display about adaptive cruise control, lane keep assist, lane departure warning, and collision avoidance system not working. Sometimes a transmission problem message would also become active. Sometimes the messages would be present at startup but other times the systems would show up green on the display and then the systems would shut off while driving causing the vehicle to suddenly slow down in highway traffic. The root issue seems to be a broken or malfunctioning multipurpose camera for the driver assist system. The camera has not been replaced yet to verify but related codes are active based on a code scanner and symptoms match what is expected for the camera failure. The vehicle is 6 years old with 99,400 miles at the first occurrence of the issue and does not have any windshield damage or signs of water leaking that would contribute to a failure. My primary concern is that the software completely disables cruise control when the camera for adaptive cruise and lane keep assist fails causing the vehicle to suddenly slow down rather than allow normal cruise control to continue operating and display the warning messages.

UNKNOWN OR OTHER
We were presented with recall information on our vehicle by Honda in August of 2026. We have called our dealership where our car was purchased to schedule the recall repairs. We have been denied 2 times for the repairs and were told they did not have the necessary parts to complete the repairs.

ELECTRICAL SYSTEM, ENGINE
My 2020 Honda Odyssey EX-L intermittently fails to restart after the Auto Idle Stop feature shuts the engine off at a red light or stop. This has happened probably 10 times in the past 6 months. In order to start the engine, I must recognize that the engine isn't starting, turn off the vehicle, and turn it back on, often 2-3 times before it actually starts. This leaves the vehicle stopped in a traffic lane at an intersection with traffic trying to pass, which creates a risk of rear-end collision or cars trying to pass me. Cars have gotten into near misses trying to pass me while my vehicle is inoperable. I have no warning lamps or messages before it happens. History: The dealer performed Honda’s idle-stop software update (service bulletin 23-008) in November 2024 at about 63,100 miles. The problem continues. The battery was replaced in December 2022, and the dealer’s October 2026 inspection rated the battery “Good.” (as did a second independent auto shop). At 93,331 miles in October 2026 the dealer documented the complaint, charged a diagnosis fee, and recommended replacing the starter motor at a cost of $954.53 plus a diagnostic fee of $184.95. I contacted Honda, which opened a case and offered only partial goodwill coverage. I am not aware of any additional recall or warranty extension covering this on my model. This appears to be the same condition as NHTSA investigation EA25004 (no restart after auto start/stop engages), which covers 2018-2025 Odysseys. The failure persisting after the software update matches the investigation’s finding that complaints continue after Honda’s countermeasures. I can share vehicle inspection records if helpful.

SUSPENSION
The rear coil springs on my vehicle failed before reaching 100000 miles. This affected the performance of the suspension system which reduced steering response and stability at highway speeds. It also likely caused early failure of the rear shocks which had to be replaced at about 105000 miles. The problem also lead to uneven tire wear increasing the risk of a tire blowout. The springs are currently being replaced with Honda OEM parts at a mechanic shop.

STRUCTURE:BODY
The power tailgate on my 2020 Honda Odyssey EX-L will not stay open sometimes. After it is raised it sags and soemtimes closes on its own, with a beep. This happened mutltiples times over the past year and a few times in XXX where it has closed on my young children while they were near or loading into the vehicle, and it hit me on the head. Nobody was seriously injured, but a heavy tailgate closing on a child's head or neck could cause serious harm. Honda service bulletin 22-018 (XXX) describes this condition and says to replace the right tailgate spring (74981-THR-A01) and clips. Honda has not issued a recall. I opened Honda Customer Care case XXX. The dealer told me Honda needs a paid $250 diagnosis before it will consider goodwill, which I declined. I am concerned this is a safety defect affecting other Odysseys and ask NHTSA to review it. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

POWER TRAIN
The contact owns a 2020 Honda Odyssey. The contact stated that while coming to a stop, the vehicle independently shifted into Park (P). The contact stated that the check engine warning light initially illuminated before the vehicle automatically shifted into Park (P); however, the failure escalated, with the vehicle shifting into Park (P) and shutting off the engine entirely without warning light illumination. The vehicle was able to be restarted following the failure. Additionally, the collision warning light illuminated on the instrument panel, with no vehicles nearby. The vehicle was taken to a dealer. The failure mileage was 55,000.

VISIBILITY/WIPER, UNKNOWN OR OTHER
Associated Recall: 26V-423 (Rearview Camera Cable Harness) Description of Safety Defect & Insufficient Recall Remedy: I am filing this complaint to report that the current manufacturer remedy for recall 26V-423 is insufficient due to a related, pre-maturely failing structural component that Honda is failing to address. The rear window seal for the glass sliding door (Honda Part # 73220-THR-A01) on this generation of the Honda Odyssey is made of a defective rubber material. On my vehicle, this seal is prematurely disintegrating into small shreds [Optional: See attached photos]. This degraded seal allows water to seep directly into the rear camera housing area. While the recent recall may have replaced or repaired the immediate rearview camera wiring, the ongoing water intrusion caused by this disintegrating window seal will inevitably cause the new camera components to fail again. Fixing the camera without addressing the root cause—the failing rubber seal letting water in—makes the current recall remedy entirely temporary and insufficient. NHTSA needs to investigate part number 73220-THR-A01 and compel Honda to issue an expanded recall to replace this seal with a higher-quality, weather-resistant material to prevent future safety failures of the backup camera system. I have already reported this issue to the service advisor on Oct 12 2026 at ourisman honda of woodbrige VA and they said they cannot help me with it and recall is not addressing the windshield molding on the rear sliding door of the minivan.

ELECTRICAL SYSTEM
While sitting at light, Idle stop engaged and engine stopped - then car lost all power. I was boxed in in heavy traffic and could not move. The car could not be shifted to neutral when I tried to consider how I could get off the road. After a minute or so power suddenly returned to the vehicle and I was able to proceed. The next day, lucklily at a less busy intersection the same issue occurred (again with Idle Stop engaged). After these events I scheduled to take to dealership. Over the next several days I made sure Idle stop was not engaged and had no further issues. Took to Honda dealership and they determined started needed to be replaced. This repair was completed at my expense.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Front Camera failure which disables the entire Honda sensing Suite, Shuts down Cruise control, lane keeping assist, front collision warning and Auto emergency braking. This has caused the loss of many safety features intended to prevent accidents and injury. There are numerous warning lights on the dash that are constantly displayed and can be a distraction to other safety or maintenance concerns. Dealer has diagnosed the problem to be an issue with a faulty front camera system. The repair for this is extremely expensive

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS, LANE DEPARTURE: WARNING
One morning, with no prior issues, we started driving our van and it suddenly displayed several warning lights, including brake system, adaptive cruise control, auto emergency braking, forward collision warning, lane departure warning, and lane keeping assistance. We took it to Darcars Honda in Bowie, MD who diagnosed it as a front facing camera failure. The dealer replaced the camera and kept the old one. This failure in a six year old van increased the danger of collision while operating the vehicle.
