Honda Odyssey EX-L sport 2025 has been facing the issue of idle stop not working causing engine to stall, engine failing to restart, shutting off completely during mid traffic especially during adaptive cruise control operation. This is causing an unsafe driving situation. While this issue was reported to Scott Clark Honda multiple times and they have claimed to fix this issue in Aug 2025, the issue continues to exist and root cause hasn't been fixed. This seems to be related towards the on-going investigation by NHTSA. Please help to resolve at the earliest since no further support is being received from Honda.

2025 Honda Odyssey EX-L My concern and issue is that the 2025 Honda. On 18 October 2025 the Honda Odyssey shuts down by its self after stopping at a red light. I believe it has something to do with the feature of auto start/stop system. This has happened multiple times. The vehicle sporadically fails to restart after coming to a complete stop. The engine shuts off as expected at a stoplight, but when I release the brake, the vehicle hesitates to crank over or start which has left me stalled in traffic numerous times. No warning lights or messages ever appear prior to the issue. This issued has left me in the middle of the road numerous time with traffic behind me. This takes a couple of minutes to restart the engine because the vehicle lights are turned on and it appears that the Odyssey doesn't have enough power to turn on the vehicle. But after multiple tries the Odyssey finally turns on. This is extremely dangerous because it can cause another car rear ending us and injuring my family.

Since July 4, 2025, this can has intermittently shut off and stalled on me, my wife and my family and has refused to start. It has now been back to the service department of Trust Honda of Palmdale 4 different times for the same problem and the battery has been replaced on this van back in July. Most recently, it stalled just two days ago in rush hour morning traffic on the 405 Freeway going South in the San Fernando Valley. The display on the dash read “dead battery “. It took over 20 minutes for the van to start and my wife was able to move it off of the freeway to a safe location.

Description of the Problem I am filing this complaint regarding a serious safety concern and poor quality repair on my 2025 Honda Odyssey, which I purchased new less than one year ago. 1. Engine Auto Idle Stop / Starter Failure Issue The vehicle suddenly shut down when the “Auto Idle Stop” feature was activated. This incident occurred multiple times, and I was unable to restart the engine until several attempts later. This creates a dangerous situation, especially in traffic or intersections. When I contacted the dealer, they confirmed that the issue is caused by a starter motor failure, and the replacement part will not be available until early November — meaning I must drive for over a month with this feature turned off. Many other owners have reported similar problems online, which strongly suggests a potential defect that should qualify for a safety recall. 2. Water Leak and Poor Quality Repair My vehicle also experienced a water leak from the roof area. The dealer attempted to fix it by simply applying sealing material on the roof molding (see attached photos). The repair looks extremely unprofessional, and I requested them to properly replace or reinstall the roof molding, but they refused. This type of repair is unacceptable for a new vehicle of this class and price. 3. Honda’s Unsatisfactory Response I contacted Honda Customer Service (1-800-999-1009) and spoke directly with a representative. However, I was told that: They cannot extend the warranty. They cannot offer any compensation or goodwill service. They cannot provide me with a record or copy of our phone conversation (even though they recorded it). They will only repair the starter once parts arrive. I explained that I have already spent time, fuel, and lost work hours visiting the dealer multiple times, yet they refused any support. Safety Concern and Requested Action The engine shut-off issue clearly affects vehicle safety and could cause accidents in traffic. I request that NHTSA inv

The issue involves the auto start/stop system on my 2025 Honda Odyssey Touring. When the feature is turned on, the vehicle intermittently fails to restart after coming to a complete stop. The problem does not occur when the start/stop system is disabled. During normal driving, the engine shuts off as expected at a stoplight, but when I release the brake, the vehicle hesitates or fails to crank, leaving it stalled in traffic. The Honda dealership confirmed the issue and stated that the starter motor needs to be replaced. The van has approximately 9,300 miles. No warning lights or messages appear before the failure. The problem occurs only when the start/stop system is active. This presents a safety concern, as the vehicle can lose power and fail to move when traffic lights change or when merging, increasing the risk of a rear-end collision or blocking intersections. The vehicle is currently being inspected and repaired by the Honda dealer and is available for inspection upon request.

The car struggles to turn over. 2.) The car struggles to start on initial start as well. The dealership replaced the battery and it continues to happen, they advised me to disengage idol stop every time I start my vehicle to save the starter and prevent the car from stalling. This is obviously a problem with the Honda idol start that needs to be addressed. There are multiple threads in online forums about this issue with Honda.

Three times now since buying my van about 6 months ago brand new, I come to a stop light, the engine turns off, but then it won't come back on when the light turns green. I have had to put my hazards on while I frantically push the start button multiple times. Eventually it will start up but takes 1-2 minutes. I brought it into the dealer the first time and they blamed it on a weak battery. After it happened 2 more times, they are replacing the starter but I'm afraid that's not going to fix it. While I wait, i just have to turn off the idle start/stop button every time I start my van.

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy. ODI is additionally expanding the scope to encompass all vehicles addressed in Honda’s service bulletins 23-008 and 23-009 as well as newer model year vehicles, which are substantially similar to the vehicles covered by the service campaign.
