  1. Other or unspecified, Engine, Sep 9, 2025

    When attempting to restart from the autostop function (i.e. the fuel economy function), the vehicle fails to restart successfully. This has happened on multiple occasions. It is not a battery problem and I have had the battery tested and even replaced (by Honda) and the problem has continued. The vehicle will stutter, stall or even completely shut down. This has happened when I have been at intersections and on busier roads or even in traffic on the highway. Its very concerning to me and seems extremely unsafe. No warning signs come in this scenario until the vehicle shuts down and the regular dash light engages indicating the engine is inoperable. I have today's date below but this has been happening consistently the last several months.

  2. Suspension, Electrical system, Engine, Aug 27, 2025

    Can has been making a popping noise that can be felt in the steering wheel for 2 years. Honda has told me nothing was wrong after taking it in 4 times. Now my car keeps stalling at lights, sometimes it takes a while to get it to restart, and they can not figure out why. They keep saying the battery is fine and diagnostics finds nothing.

  3. Electrical system, Fuel/propulsion system, Forward collision avoidance, Aug 25, 2025

    Vehicle applied brakes for no reason. Lost ability to see reverse camera during backing up. Half of the instrument cluster went dim to become barely visible. Radio screen freezes randomly. Engine cuts out or shudders intermittently.

  4. Suspension, Aug 24, 2025

    Approximately May 2023, while pulling away from stop light, heard loud pop (like gunshot inside vehicle) and vehicle shuddered/jolted. It feels almost like someone hit vehicle with sledgehammer. I looked underneath but no issues found. No bump in road was hit at the time. December 24th 2024, while moving at less then 5 mph, heard another loud pop and shudder/jolt. Someone sitting in the back thought that something fell on the vehicle. This time noticed that left rear tire was into wheel well with vehicle unloaded. After pulling wheel, found left rear coil spring broken in 2 places. Believe broke first in 23 and again in 24. At time, we were 1200 miles from home and needed to delay trip so Honda in Killeen TX could repair. Dealer service advisor stated they had never seen anything like that except from crash. June 19th 2025. On highway doing 70-75 mph when heard another loud pop and shudder. No pot hole or any significant bump hit. Stopped, pulled wheel, and found right rear spring broken. Honda dealership in Marysville OH unable to find new spring either through OEM or aftermarket. We have also been unable to find aftermarket or junkyards. Being told that there is a nationwide backorder and no eta for when replacment parts are going to start being available. So being forced to continue driving a vehicle that is unsafe. First this does not seem normal for springs just to randomly break. Second for a critical suspension component on a relatively new vehicle, why is manufacturer unable to proved parts. We are now 2 months into it being broken and can't even order replacment parts yet because Honda is not allowing orders to be placed.

  5. Engine, Aug 20, 2025

    While stopped at a stop light at an intersection in our 2021 Hond Odyssey, the idle auto off feature kicked in, and then as we let off the brake and went to hit the gas to move forward the car shut off completely. The car had to be restarted by applying the brake and pressing the start/stop ignition button. This is not the first time this has happened with this vehicle. This also happened a series of times in 2023 and Honda performed a series of software updates, replaced the battery, and replaced a sensor on the battery. However, now two years later the idle auto off issue occured again.

  6. Electrical system, Aug 11, 2025

    There is a message that pops up in our front touch screen panel " com.honda.auto.hars has stopped" which is not allowing us to use the touchscreen panel.for anything - from making or receiving calls , navigation , etc .. , which makes it hazardous to drive the vehicle on the road & not able to use hands free. We tried factory reset & also using USB drive to update , but the car is not recognizing the USB drive & also says that our system is up-to-date!! We are not able to find a solution . Please help . Advice needed.

  8. Electrical system, Jul 14, 2025

    The vehicle's Auto Idle Stop (AIS) malfunctioned. The vehicle stalled and required a complete "shut down" to restart. The vehicle was first in line at a traffic light. The AIS system engaged. When I took my foot off the break to "go" when the light turned green, the car stalled. An error message popped up, indicating that I needed to shift the car into "park". I did so and the car did not start. I attempted to turn the car off several times, while in park and my foot depressing the break pedal. The car would not turn off. After three minutes of attempting to turn off the car and waiting, I was finally able to successfully start the car. I was traveling with my four young children, three of them in child car seats. I was nearly rear ended by one vehicle, despite having my hazard flashers on, because my car stalled at a traffic light when it was green. Two cars drove around me who were also stopped behind me at the traffic light. Another car came up to the traffic light and my vehicle and nearly rear ended me with my four young children in the car. This is the third time that this exact issue has occurred in my car. I brought it to my local Honda dealership on the same day that the issue first occurred. They inspected it but were unable to replicate it. They said they would make note of it but had not heard of such an issue. I had no idea this could be reported on this website. I was never told about this otherwise I would have reported this on the day that each of the two previous incidents occurred. This issue originally occurred the first time approximately 10/2022 and again for the second time approximately 4/2023. It just occurred for the third time today, 7/14/0225.

    2021 Odyssey EXL shuts off completely in traffic stop and go conditions. Happened three times in a 2 week period. Twice in city roads at traffic stop light and once in highway when the cars are in stop / go mode due to heavy traffic. Engine switches off completely and puts itself in "P" mode, all light comes on as if in accessory mode, radio switches off, all doors unlocked. To get going, the driver had to press brake pedal and start the car again (via Engine Start /Stop button). This issue started in the car at 43K miles. Never had any issue with mine before that. But it is scary especially the engine switch off in highway and traffic stop light.

  17. Electrical system, Lane departure, Forward collision avoidance, Apr 3, 2025

    It started that all the sensor in our car started to go off. We were told we had a bad battery, even thought we had replaced it new just last year. Once we had the battery checked and alternator. The sensors started to act up again, out tail gate started to malfunction. Wouldn’t automatically close. A few weeks ago driving down the road the tail gate opened and the anti theft system started going off while the car was running and still going. Come to find out there is a water leak in the rear that has gotten into the rear fuse box and has cause substantial corrosion. The latch to the tail gate is broken. Honda is telling us our extended warranty doesn’t cover any of this, even though it is common knowledge, that the water leak is a known problem from 2018-2021. We just found out a few days ago.
