ELECTRICAL SYSTEM
The Auto Idle feature has caused my car to stall multiple times. This is extremely dangerous because it always happens when I am in populated areas- sometimes at red lights and another time in stop/go highway traffic. My car is 1.5 years old and this keeps happening more and more frequently. I am very concerned that one of these times I am going to be rear ended because traffic starts to go, I let off the brake to drive and then my car stalls. I then have to turn my vehicle off completely and then back on to get it to not have issues. I do get a warning saying to depress the break and press the start button. Sometimes I get a red battery light on the dash.

ENGINE, ELECTRICAL SYSTEM, POWER TRAIN
The vehicle's Auto Idle Stop (AIS) system engaged normally when coming to a complete stop at an intersection, shutting off the engine to save fuel. However, when attempting go through the intersection after the light changed to green, the engine failed to restart automatically. The vehicle completely lost power in an active lane of traffic, creating a safety hazard. The vehicle had to be shifted into park and manually restarted to clear the roadway. This failure appears directly related to NHTSA Engineering Analysis EA25004 regarding Honda/Acura Auto Idle Stop restart failures.

POWER TRAIN, UNKNOWN OR OTHER
The vehicle is experiencing an intermittent but highly dangerous defect involving the factory-installed Auto Idle Stop system. When the vehicle comes to a complete stop at intersections, traffic lights, or in stop-and-go traffic, the Auto Idle Stop system engages as designed and shuts off the engine. However, upon releasing the brake pedal to accelerate, the engine fails to restart automatically. Instead of seamlessly restarting, the vehicle completely stalls in live traffic. The dashboard instruments remain on, but the engine drops completely out of operational mode. To recover propulsion, the driver must shift the vehicle entirely into Park, press the start/stop button to cycle the ignition completely off, and then manually restart the engine. This creates an immediate and severe safety hazard. The sudden, unprompted loss of propulsion leaves the vehicle completely stranded in active intersections and roadway lanes, exposing the occupants to an imminent risk of a rear-end collision. The restart delay forces the driver to perform multiple steps to reset the vehicle while traffic builds around them. The manufacturer is aware of similar systemic restart failures across its V6 engine platforms, which are currently the subject of active NHTSA investigations and class-action litigation. However, this issue continues to persist on the newest model years, creating an active road safety risk.

ELECTRICAL SYSTEM, ENGINE
The Auto Idle Stop (AIS) on our 2025 Honda Odyssey will cause the van to stall and the engine will not restart. When this happens, our only option is to put the van in park, shut it down and then restart. Sometimes that van has not restarted for almost 90 seconds. We have had it into the Honda dealership three separate times for this issue. The first time they told us the battery was drained so they recharged for over eight hours. The last time they said "the battery fails the load test at this time" so they replaced the battery and stated that the vehicle was "operating as designed at this time." Since the last time we had it in for service (and with a brand new battery), the AIS has failed on us twice. The last time (XXX) it nearly caused an accident on a busy road in Northern Virginia. When it fails to restart the van goes into a default type mode (where most of the service lights turn on or flash and we will have to put the hazard lights on, put the van in park, shut it off and then restart the van. This issue has happened to us about 12 times int he last 8 months. I am very concerned that this will cause an accident at some point and is putting my family's safety at risk.

POWER TRAIN, ELECTRICAL SYSTEM, ENGINE
We have been experiencing issues with the car stalling while driving. Most recently, the car lost power a few feet into making an unprotected left turn leaving us stranded in the middle of an intersection in a vulnerable position for several minutes. This was deeply unsettling to have happen while making left turn maneuver. It seems to be a failure of the Auto Start/Stop function. After a few persistent trips to the dealer, they have now informed us that this is a known issue, but the parts are on backorder until January 2027. The workaround is turning off the Auto Start/Stop function, but this button does not have an indicator light, is not always confirmed on-screen, and is re-enabled by default EVERY time the car is started. It also appears that others have complained about this issue, and this deserves to be upgraded to a recall. It is unacceptable that a manufacturer would know about an issue with serious safety implications and not notice owners. This could have easily caused a crash and it is happening to others. This specific van is used to transport a disabled family member and outside aides often drive him in this car. We do not feel comfortable with a non-persistent workaround while others are driving this car while we wait for this part. - Auto Start/Stop and Drivetrain, available for inspection - Car stalls during maneuvers after stopping - Problem was reproduced multiple times. Dealer is aware. - Inspected by dealer. - No warnings, messages, or symptoms.

ELECTRICAL SYSTEM, ENGINE, UNKNOWN OR OTHER
My 2025 Honda Odyssey has repeatedly failed to restart after the Auto-Idle Stop feature automatically shut off the engine while idling in traffic. This is a serious safety hazard that could leave the vehicle disabled in a busy intersection, exposing occupants and nearby motorists to the risk of a potentially catastrophic collision. Despite two starter replacements in October 2025 and October 2026, the problem has occurred multiple times. The authorized Honda dealership acknowledged this is a known issue but stated that no permanent solution is available. No warning messages were observed before the failures. A vehicle that can unexpectedly become inoperable in traffic presents an unacceptable safety risk and warrants urgent investigation and corrective action. Please associate the above statement with EA25-004.

ELECTRICAL SYSTEM, ENGINE
When idle start activates at a stoplight sometimes the car will not start when you take your foot off the brake. Car then takes several tries but it will start again. This is a dangerous situation and can lead to accidents. Only seems to happen randomly after the car warms up. Dealer did replace the battery but it did not fix the problem. My guess is the starter does not perform correctly after heat soak in the engine bay.

ENGINE
I've had multiple instances where I would be stopped at a red light, when when the light turned green, the car would not accelerate. I would have to turn the engine completely off and back on. This is a safety issue as I'm sitting in traffic and cars/vehicles behind me are expecting me to go. My fear is that someone not be watching my van but the light and accelerate before I am able to move forward. My son, a mechanic, looked at the vehicle. His suggestion was to replace the battery - the vehicle was purchased March 2025, and should be too soon to have to replace the battery. However, when attempting to start it, it sounded like the battery was dying. A couple of weeks after replacing the battery, there had been no issues. I had been driving the vehicle around 20 minutes, most of that at highway speed (80MPH on the toll road). I was idling at a red light. When the light turned green, the vehicle would not come out of the idle mode. I could NOT switch from drive to park. I could NOT turn off the engine. I sat in the road for a minute and a half to 2 minutes (as I sat through an entire light cycle) before the van would finally allow me to turn off the engine and turn it back on. There was no warning, messages or other issues prior to this happening.

UNKNOWN OR OTHER
I am providing formal notice of a recurring defect involving my leased 2025 Honda Odyssey Sport-L and requesting prompt investigation and resolution under Honda's warranty and applicable Maryland law, including the Maryland Lemon Law. I leased the vehicle on XXX, with approximately 18 miles. It currently has 17,370 miles and has been maintained at authorized Honda dealerships. The vehicle has repeatedly failed to move from a stopped position. On XXX, Heritage Honda of Westminster documented the issue (Repair Order XXX), recording a flashing "D," inability to shift, a transmission-system warning, and Diagnostic Trouble Code P07E4. The code was cleared, but no repair was made because the problem could not be duplicated. On XXX, the defect occurred again while I was stopped at a busy intersection with my five children in the vehicle. When traffic began moving, the vehicle would not move, the dashboard went black, and the vehicle required multiple restart attempts before operating again, creating a serious safety concern. Because this defect has recurred after a documented service visit and remains unresolved, I request that Honda open a case, perform a comprehensive diagnostic evaluation and repair, provide copies of all diagnostic findings and repair records, advise me regarding a loaner vehicle, and confirm the warranty and any applicable Maryland Lemon Law remedies. Please preserve all records related to this matter. I reserve all rights available under applicable state and federal law. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ELECTRICAL SYSTEM, UNKNOWN OR OTHER, POWER TRAIN
The vehicle idle start/stop feature has started struggling to reengage, particularly, it seems, in warmer weather. At least six times in the past two months (Sept-Oct 2026), the start fails completely during a drive. What this means is that the vehicle is stopped at a light and the start/stop kicks in. When I lift my foot off the brake to prepare to drive again, a warning flashes on (it disappears quickly but says something was detected) and the car shifts into park. I cannot put the vehicle into drive without turning off the car and turning it back on. This is very dangerous as I have been at the front of and in long lanes of traffic. Other drivers honk and try to go around me while I am getting the vehicle back up and running. The dealer has checked the car twice but cannot replicate the issue (both days they had the car, the temperature outside was below 80 degrees, and that seems to be a factor). Therefore, they cannot make or recommend any fixes other than turning off the feature everytime I turn on the vehicle.

When starting the car it takes a long time to officially start. This could leave me stranded. A Honda dealer has confirmed this is an ongoing issue as well as other car shops. It started to appear a few weeks ago. I have video I can send. The auto start stop system has shut the vehicle off in the middle of an intersection which could cause an accident or me being stranded.

ELECTRICAL SYSTEM, ENGINE
The auto start-stop system fails frequently. If I do not turn off the system, when I stop on red light, the engine turns off as expected. However, it frequently fails to start. The car stalls and it's difficult to turn back on. I need to turn the car off completely first, then try to turn it back on. This usually takes 10-20 seconds. The situation presents a safely hazard as I'm not able to continue to drive through an intersection on a green light. I took the car to dealer 3 times. They were not able to reproduce he issue nor find the cause of the problem

UNKNOWN OR OTHER, ELECTRICAL SYSTEM, SEAT BELTS
Unknown. **Vehicle:** 2025 Honda Odyssey Touring **Component:** Engine / Electrical System / Automatic Idle Stop My 2025 Honda Odyssey Touring has repeatedly failed to restart after the automatic idle-stop system shuts off the engine while stopped in traffic. This problem began very early in the vehicle's life, at approximately 10,000 miles, and has occurred an estimated 8–10 times. The vehicle currently has 40,340 miles. When the problem occurs, the engine does not crank or make any clicking sounds. Multiple attempts are required before the engine will restart. On at least one occasion, the dashboard displayed the message "Press Brake and Push Start." I cannot confirm whether this message appeared during the other incidents because I was focused on getting the vehicle restarted and moving out of traffic. The problem has occurred exclusively following activation of the automatic idle-stop system. The vehicle starts normally when initially started after being parked. This presents a serious safety concern because the vehicle becomes unexpectedly immobilized at traffic lights or intersections, potentially exposing occupants to rear-end collisions or other traffic hazards. Honda issued a dealer communication dated May 21, 2025 (NHTSA document MC-11019246-0001), specifically concerning 2023–2025 Honda Odysseys failing to restart following automatic idle-stop operation. I am requesting that NHTSA investigate this recurring safety defect.

SEAT BELTS
My 2025 Honda Odyssey Touring has developed an intermittent malfunction involving the second-row passenger-side seatbelt buckle and warning system. The problem began at approximately 39,000 miles. The vehicle currently has 40,340 miles. The seatbelt warning system intermittently activates and produces repeated audible chimes even though the passenger's seatbelt is buckled. The warning can be triggered or interrupted by physically moving or wiggling the seatbelt buckle or latch assembly. This suggests an intermittent malfunction within the buckle assembly or its associated electrical components. I am concerned that the buckle assembly may be defective. Although the warning system is detecting a change in buckle status, I cannot determine whether the problem is limited to the electrical sensor or also affects the mechanical integrity of the buckle. This presents a potential occupant safety concern and causes repeated driver distraction due to false seatbelt warnings. I am requesting that NHTSA investigate this possible seatbelt buckle defect.
