ELECTRICAL SYSTEM, ENGINE
Vehicle experiences engine stalling and failure to restart at intersections when the Auto Idle Stop (AIS) feature is engaged. This creates an immediate life-safety hazard as the vehicle becomes non-functional in live traffic. This has occurred 2 times. Once on surface streets and once on the highway in stop-and-go traffic. This issue persists despite Service Bulletins 23-008 and 23-009. Honda Corporate and Honda Dealership refusing to cover the repair. Separately, during a 37-day repair attempt (Jan 22 – March 2, 2026), AutoNation Honda Chandler admitted the vehicle was sold with an 'incorrect' battery type (Lead Acid instead of required AGM), which caused electrical instability. The dealership attempted a repair on Feb 13, but the vehicle failed to start again on Feb 11 during a pickup attempt. The dealer has since refused to provide accurate service records or further communication. The vehicle remains unsafe to drive as it continues to stall randomly.

STRUCTURE:BODY
Both rear power sliding doors on my 2019 Honda Odyssey failed at approximately 74,000 miles. The sliding door motors can be heard running, but the doors do not move and cannot be opened normally. The doors are available for inspection upon request. This failure prevents rear passengers from safely exiting the vehicle. In an emergency situation, this could prevent evacuation and creates a serious safety risk, especially when transporting children or passengers seated in the rear. A dashboard warning message related to the sliding doors appeared at the time of failure. The condition occurs consistently on both doors. The vehicle was inspected by an authorized Honda dealer, who confirmed a malfunction in the sliding door system and provided a repair estimate. The vehicle has not been inspected by police or insurance representatives. This appears to be a significant sliding door system failure affecting both rear doors simultaneously.

ENGINE
While driving on I-85 in GA in 2024, my engine started to misfire and I had to pull over. At that point, I turned the engine off. If this had happened in the evening or on a road without a shoulder, I could have been at risk of being hit and/or stranded. After waiting a dew minutes, I restarted the engine and was able to make it home. My husband took it to our mechanic who indicated that the engine had registered a cylinder misfire (DTC P0303). Apparently, this was a serious flaw recognized in earlier (2008-2013) Honda Odysseys with Variable Cylinder Management (VCM). See [XXX] , et al. v. American Honda Motor Co. Inc., Case No. XXX, in the U.S. District Court for the Northern District of California. I received a notice from American Honda concerning a warranty extension related to TSB 25-061, which would seem to indicate that this is a known flaw that should be handled as a safety recall.

ENGINE
I have a 2023 Honda Odyssey. The engine is making a knocking noise. The oil has just been changed with 5.7 quarts, following the factory specifications, but the knocking is still there. The timing belt tensioner has also been replaced, as well as the high-pressure fuel pump. However, the knocking noise is still present, especially at low speeds.

FUEL/PROPULSION SYSTEM, ENGINE, ELECTRICAL SYSTEM
The vehicle was stopped at a red light. This vehicle is equipped with an auto-start/stop system to save fuel. Once the red light turned green the engine refused to restart. This was the second instance. The vehicle took over 30 seconds before it would restart. None of the push-to-start buttons worked, the car would not recognize that the brake was pressed, and it had also shifted itself into park. Very dangerous while traffic was moving all around us.

ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL, STEERING
I am submitting this urgent complaint regarding my 2015 Honda Odyssey, equipped with the 3.5L V6 engine referenced in (TSB) 20-023 which acknowledges that the front rocker arm oil control valve (spool valve) gasket may fail and leak engine oil directly onto the alternator located beneath it. This condition can cause alternator contamination, charging system failure, electrical malfunction, and potential fire risk due to oil exposure to electrical components. Despite knowledge of this issue, Honda did not notify vehicle owners and did not initiate a recall. Before the first breakdown occurred, I experienced a frightening and dangerous incident while in traffic. Without any human interference and without my pressing the accelerator, the vehicle suddenly accelerated and moved forward on its own, nearly striking the vehicle in front of me. I had to react immediately to prevent a collision. This unexpected surge was extremely disturbing and appeared to involve an electrical malfunction. Shortly thereafter, the vehicle broke down. After the first breakdown, I replaced the battery. Within approximately one hour of driving again, the vehicle failed again due to alternator failure. I was stranded at night, in darkness, alone, and exposed to active traffic. This created an immediate and foreseeable risk of collision, serious bodily injury, or death. Another car in that area around that time broke down on the highway I was expected to use and was hit by a semi on 95 and the driver of the stopped car was killed. That could have easily been me. A defect that can cause sudden electrical malfunction, unintended vehicle movement, loss of charging capability, vehicle disablement in traffic, and potential fire hazard constitutes a safety-related defect under federal motor vehicle safety standards. I respectfully request that you Initiate a formal investigation Evaluate whether a recall is warranted. Require reimbursement for repair costs Thank you very much.

AIR BAGS
On 2/27/25 while driving my 2019 Honda Odyssey on the hwy the passenger side curtain airbags deployed after running over a pothole in the road. This frightened my wife and may it very difficult to see to pull over safely on the side of highway. There were no passengers in the car when it happened, no injuries or collision following g the deployment. We were very lucky. Police officer would not provide report because accident did not occur. Officer sated he had never seen airbag deployment cause by pot hole. My wife’s safety and the safety of others on the road that day were definitely at risk due to this unannounced airbag deployment. We did take to dealer and we were never given explanation of why it occurred. Damage caused by airbag deployment cost over $8,000 dollars in repairs and my wife still does not feel comfortable driving this vehicle. Now a year later we are experiencing electrical issues in the vehicle on the passenger side with power windows and locks. We feel that it is related to incident. Original Repairs were completed by dealer but they are now looking into electrical issues. There were no warnings or light prior to deployment.

AIR BAGS, SEAT BELTS
My driver seat belt keeps unlatching . It happens to often. I know there was a previous recall for it but everytime I look it up it doesn’t show on the website. I previously reported here I think last year. Also when shows as an error on the obd reader. As a failing seat belt system recall. My insurance company shows the driver air bag is recalled but again when I look it up here . You list no information about these recalls and it’s scary since both are critical.

FORWARD COLLISION AVOIDANCE: WARNINGS, LANE DEPARTURE: WARNING, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The car has started giving warnings every time I turn it on (as of 6 months ago): adaptive cruise control problem, collision mitigation system problem, auto high beam problem, lane keeping assist problem. It seems there must be a fault in the windshield camera that renders all these safety features useless. The repair shop stated that windshield camera isn’t working and is a $2k or more to repair. I am now driving a minivan that doesn’t have many important safety features and this is very dangerous.

POWER TRAIN, ENGINE
My 2019 Honda Odyssey is currently diagnosed with a connecting rod bearing failure, which matches the safety defect in NHTSA Recall 23V-751. While my VIN is excluded, I am reporting this as part of the NHTSA Investigation PE25-008. For several months leading up to the failure, I noticed a faint, repetitive knocking sound coming from under the hood. During my regular service visits to authorized Honda dealerships (including a visit in December 2025 at approximately 80,000 miles), I mentioned these unusual noises and asked the technicians to verify the vehicle's safety. On at least one occasion, repairs were made to the steering system to address noises, but the engine knocking persisted and eventually worsened until the rod bearing failure was confirmed in January 2026. This defect presents a serious risk of sudden engine seizure and loss of motive power at highway speeds.

STRUCTURE:BODY
I am filing a formal safety complaint regarding a dangerous manufacturing defect in my 2018 Honda Odyssey EX . A structural failure of the factory roof seam sealer (ditch molding) is allowing rainwater to pour directly into the vehicle's cabin, severely compromising critical electrical modules and creating major safety hazards. This water intrusion has caused two distinct and dangerous electrical failures: 1. Entrapment Hazard (Power Sliding Doors): Previously, water leaked into the rear fuse box area, causing the power sliding doors to completely fail and become completely unopenable. Transporting a [XXX] and a [XXX] in the rear seats, the sudden inability to open the sliding doors creates a terrifying entrapment hazard. In the event of an accident, fire, or emergency, I would be unable to evacuate my young children from the rear cabin quickly, posing an immediate threat to their lives. 2. Cargo and Security Hazard (Power Tailgate Control Module): Currently, the water leak has short-circuited the Power Tailgate Control Module. The system operates erratically: the tailgate automatically pops open as soon as the engine is turned off, and it refuses to open manually. Beyond the security risk, this electrical short could cause the tailgate to unlatch unexpectedly while the vehicle is in motion or stopped in traffic, potentially dropping cargo onto the roadway and creating a crash hazard for other drivers, or allowing carbon monoxide exhaust to enter the passenger cabin. This is a well-documented and widespread structural defect affecting many 2018-generation Honda Odysseys. Water destroying critical safety modules (doors and tailgates) is a severe design flaw that goes far beyond normal wear and tear. I strongly urge NHTSA to open a formal investigation into the roof seam sealer failures on the 2018 Honda Odyssey. A safety recall is necessary to force Honda to repair the structural leaks and replace the compromi INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE, POWER TRAIN
Our 2019 Honda Odyssey EX-L was our primary family vehicle. We conducted all routine maintenance as required by Honda, including transmission fluid exchange. Our vehicle experienced rough shifting consistently and at 102,000 miles experienced a total failure in the transmission dog clutch, with Emissions lighting also being present. Vehicle required a tow to Honda and was cited" internal failure in the transmission. The confirmed related DTC's are P0841: Transmission fluid pressure sensor/switch A circuit range/performance; P0844: Dog Clutch malfunction; P0170A: Dog Clutch Abnormal operation. Parts $:5,736.73/Labor $2,385 plus fluids and freight. We were not aware Honda used the ZF transmission during this year model and experiencing rough shifting up to 102,000 miles which prompted our investigation. Thankfully, the car was parked however, had this been while on the road, this would have presented a major safety and risk to our family and others. This has set our family back quite a bit as we have to replace the transmission and cannot guarantee the new one won't provide similar issues. Honda denied our good-will assistance request. We bought a Honda under the assumption it was a reliable brand. We will never buy Honda nor recommend again. Terrible experience.

Vehicle stalled and shut down in traffic after the Auto Idle Stop function engaged at a red light turning the vehicle off and attempting to turn back on. All warning lights flashed. Vehicle would not turn on until after multiple attempts pressing ignition. This has happened multiple (3-4) times over a few months period. Honda dealership was unable to recreate incident but did identify difficulty with engine starting (i.e. slow crank) when manually turning on ignition; however, diagnostics found no issues.

ELECTRICAL SYSTEM, BACK OVER PREVENTION: WARNINGS
I see the NHTSA is aware of the issue with Honda Odyssey AutoStart failing to restart the engine which causes the car to need to be restarted fully while stopped in the middle of traffic. I had this issue many times, my car was serviced with a new battery and 2 months laters its starting again. As an aside one of the front parking sensors will randomly go off which can often cause me to turn off the array. Cleaning didnt help.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
The front-facing camera stopped working, and all associated ADAS systems no longer functioned (Adaptive Cruise Control, Automatic Emergency Braking, Forward Collision Warning, Lane Departure Warning, Lane Keeping Assistance). Several errors needed to be cleared every time the vehicle was started. Our Honda dealership determined that it was a failed Multipurpose Camera (code U3000-49), and that the entire camera unit needed to be replaced and re-calibrated.
