2025 HONDA ODYSSEY Complaints

while stopped at a redlight the auto idle stop engaged and engine shut off. When releasing the brake to accelerate the engine failed to restart and completely stalled in traffic requiring a manual restart. warning lights flashed on the dashboard. Then the same thing happend when stopped at a stopped sign.

Our 2025 Honda Odyssey has now experienced three failures for the same defect, including two starter replacements within two weeks, without resolution. The most recent repair, overseen by Honda Tech Line, happened after the vehicle died June 2 while in traffic and it had to be towed to the local dealership using our insurance. On June 15 the vehicle died again, just five days after I picked it up with assurance that this issue was resolved, and it is was towed back to the dealership by Honda Towing. The repeated part swaps, without root-cause diagnosis, clearly have not resolved the issue and have left us with a one-year-old vehicle that is unreliable and unsafe to operate. My minivan has failed in the middle lane of a major road while idling at a stoplight twice and in a parking lot once. All incidents were within 15 minutes of driving and 5 miles from my home. This is a critical safety defect and the repeated failures place this vehicle within the criteria that may qualify under Kentucky’s lemon law. We have not made that claim yet, but we are formally documenting the repair history and escalation. ———- -Starter failed and was replaced twice. This could have something to do with the auto start/idle system. -our one year old van is unsafe and unreliable. It died near a major intersection while idling at a stop light. I was in the middle lane and it wouldn’t restart for 5 minutes. I was very afraid my children and I would be rear ended. -the dealership has confirmed the problem, but they not been able to recreate the scenario despite it happening on 3 separate occasions. -Honda Tech Line has been directing the local dealer what to do after the first starter replacement failed. I filed a claim with American Honda. -no warning lights/lamps prior to failures

Van has repeatedly stalled during the idle stop restart process when stopped at a stoplight. The van will stall and the dashboard lights up with many symbols. To briefly include, a red exclamation, check engine and battery symbol among others. The car has to be completely shut down and restarted to turn over and function. Obviously an unexpected stalled vehicle in traffic is a significant and potentially injurious or deadly problem. This has been happening periodically since Jan 2026 on a 1 year old van with approximately 12k miles. I have asked the dealer to investigate and they claim no error codes and the battery is ok. I suspect either a starter, brake pedal issues, or software update is needed. I would encourage the NHTSA to issue a recall or service bulletin as a quick google search reveals this is a common issue on newer Odyssey vans. This vehicle is available for inspection upon request.

My vehicle has failed to restart at intersections when the idle start stop feature is engaged. Have to put car in park and manually shut off car and restart the car to get it to restart. Get an error code for a little while about brake issue.

When I come to a full stop and the Idle Stop feature engages, sometimes the engine will not restart. I get a message saying to press the button to start the engine, but it does not start after doing that either, so I have to shut the car off and restart it. There are a bunch of lights that flash when this happens.

While in traffic, the van goes into idle and then will not restart. This has happened to us at least 5 times. The frequency has increased and now occurs at least once a week. We are very much worried about how unsafe this is because we could be hit from any direction while in active traffic. We noticed NHTSA investigation (ID# PE25-03) is already underway and feel that the issues apply to our situation. We need immediate help please.

My 2025 Honda Odyssey fails to restart after the Auto Idle Stop (AIS) system engages at a complete stop at traffic lights and intersections. When I release the brake, the engine does not restart as designed. I am forced to shift into Park and manually restart the vehicle using the ignition button. This has occurred multiple times and is intermittent. I am aware of NHTSA engineering analysis EA25004 covering this exact issue on 2018-2025 Honda Odysseys. Honda TSBs A23-008 and A23-010 have not yet been applied to my vehicle. This defect creates a safety hazard as the vehicle is unable to proceed through an intersection when traffic clears. Additionally, after driving for 20+ minutes, if I stop the vehicle and then try to restart within 5-10 minutes, the restart is very slow, almost sounding like the battery is not strong enough to turn over. I have to turn off the vehicle and then press start a couple of times to get it to work. If i then proceed for another 5 or so minutes, turn it off for just a couple of minutes and restart, it is dead with no sound on the initial restart atempt and I need to try a couple of times. You ask for a date below. This has been recurring since purchased the car in September of 2024

The van has intermittent warm-start slow cranking and occasional Auto Idle Stop restart failures. The van fails to start intermittently during auto idle stops. This puts the driver and passengers at risk by failing to drive right away. It causes a potential collision from the rear. It has not been reproducible by the dealer and was inspected by the dealer. No warnings were present prior to failure. This started happening about 2-3 months ago.

My 2025 Honda Odyssey Elite repeatedly shuts off completely while stopped, with the Auto Idle Stop feature engaged, and fails to restart on its own. The engine dies at a complete stop and will not restart until I shift the vehicle into Park and manually restart it. This has happened more than six times. It occurs only at complete stops such as traffic lights and stop signs. No warning light illuminates. This creates a safety hazard because the vehicle is dead and immovable in active traffic until I can restart it, exposing me and my passengers to rear-end collision risk. This matches the known Auto Idle Stop defect already under federal investigation for this vehicle.

When the engine shuts off while braking at a light/stop sign etc occasionally the car will fail to turn the engine back on and the car will go in to park and the only way to get in to drive is to restart the car. This happens once or twice a month.
