Engine recently began making noise and the car was taken into Honda. The dealer checked engine components to find the cause and recommended that we remove oil pan to inspect the issue because they assumed it might be engine bearing related. Before we could schedule the service I was driving with my family on the highway when we heard a loud noise and complete loss of power. I was able to move over avoiding other cars to reach the shoulder and come to a stop. The car would not start or go into any gear. Car was towed to shop. What component or system failed or malfunctioned, and is it available for inspection upon request? The car has not been inspected yet. Currently at shop being evaluated. Has the problem been reproduced or confirmed by a dealer or independent service center? Engine was making noise at the dealership when it went for service. There was no concern made by dealer stating car was unsafe to drive. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Was inspected before the car broke down, but currently being evaluated by local shop. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There was an unknown noise coming from the engine, and dealer stated they needed to remove oil pan to diagnose the noise but stated it could be bearing related. The dealership did not say the car was unsafe or should not be driven. Before we could look into the issue more the car broke down on the highway.

Honda has been serviced at Honda of Ames #190 since 2022. 2023 - Issues with the engine stalling when it goes into idle mode at a stop. September 2023 – contacted Honda of Ames, IA dealer. They indicated it’s the battery which will need replaced. Took the car to Interstate Battery on 9/26/2023 where it tested at 12.5 volts out of possible 12.6 volts. Then took the car to dealer who insisted it was an issue with the battery. Replaced battery for $391. Problem continued. In 2024 there was a recall re: a known issue with the engine idle functionality requiring a software update. Took the vehicle in for the software update. Complained to the dealer that I unnecessarily spent $390 on new battery when that wasn’t the issue. They refused to refund any money. Problem persisted. On 5/21/2025 the car was brought into dealership for 100k service. I complained again that the auto-idle feature still stalling. Was told that it's not a universal known problem, they don’t have a fix that he’s aware of other than to check the battery. I explained we’ve been through this before and brought up Sept 2023 battery situation. He stated that the quick/handheld battery testers are not reliable; repair shops have “the big testers in the back” that are more reliable – that is what they will test my battery on. I asked if they could turn off the feature permanently and was told no. When car was ready I was told that the battery life tested fine. They did a software upgrade and I will need to drive it and just see if the stall issue continues. He repeated that it’s not a “universal known problem” and there was nothing further he could do. 7/5/2025 – the auto-idle has stalled twice since the service on 5/21/2025. Stalling in an intersection, at a red light, bottom of an off-ramp, etc.i s a serious and highly concerning safety issue.

Subject: Urgent Vehicle Safety Concern – Sudden Malfunction and Safety Risk On [XXX], at approximately [XXX, I experienced a traumatic incident when my vehicle unexpectedly malfunctioned while I was driving home. After making a left turn on a green signal from [XXX] toward the Community, the car suddenly stalled. By God's grace, I managed to cross Woodbridge Avenue before stopping, avoiding a major traffic obstruction. However, it came to a complete stop in the middle of the street, creating a hazardous situation. After a brief pause, the car moved approximately 10 yards before stopping again, becoming completely immobile in the middle of a public road. Attempts to jump-start the battery failed. All warning lights turned on, but the engine would not start. The vehicle could not be restarted or moved under its own power. 911 was called, and police responded promptly to the scene. With the assistance of my wife, police officers, and local neighbors, a tow company was called to remove the vehicle from the roadway. It was then towed and parked in a nearby lot. This incident was highly traumatic and posed a serious threat to my safety, my family's safety, and the safety of the public. Diagnostics and expert assessments indicate the issue may be related to a manufacturer defect, which is deeply concerning given that this is a new vehicle. At this time, the vehicle is no longer drivable. I am seeking urgent assistance to resolve this matter with the manufacturer and to ensure that other consumers are not exposed to similar risks.

Auto Idle Stop (AIS) system. had many of the other same symptoms that people reported. our car would go into idle mode and then it would not restart. I would have to turn the car off I tried to do various things just to get it started again. this happened one time was the exited the highway and also happened coming out of a car wash location. I took it to Honda and they said because of the idle stop functionality the starter went bad and they had to replace that. I was compensated some money from Honda but I believe I was only done so because they knew something was wrong and I really believe there should be a recall for this. it is completely unsafe and very scary when it happens especially in the middle of traffic. our starter was replaced because of this issue on November 5th 2024, but the symptoms had been going on for that whole calendar year prior

The idle start stop feature constantly doesn’t work. When stopped at a light or stop sign the engine will turn off and when I release the break it is supposed to reengage the engine. Instead it stalls out causing me to have to put the car in park and restart the car. There have been several incidents where this is during rush hour traffic causing traffic jams. Sometimes I have to wait a few minutes before it will actually turn over. The car is 5 years old and I have had the replace the battery twice and I have been told that this feature puts a lot of pressure on the battery. Never can the dealership recreate the issue.

I was stopped at a light at a busy intersection and when I went to drive when the light turned green, my van did nothing. It had turned off the engine when I stopped at the intersection. I tried to switch gears and it wouldn’t change. I was kind of panicking because I was holding up a ton of traffic and my toddler was in the backseat so I can’t remember exactly what was happening on my dash. I would turn the car on and off but I could not get it back into drive as the engine would not restart, but all of the electronics were still working. Finally someone offered to jump the car with one of those portable battery jumpers and that worked. I drove straight to Autozone to see if it was something their machines would pick up on but they couldn’t find anything wrong. The dealer also couldn’t find anything wrong. I believe this is related to the auto idle stop feature.

My 2020 Honda Odyssey died at a stop light while driving on 5/12/2023. The auto on/off feature caused the van to turn off at a stop light and then there was not enough power in the battery to start the car again. It had to be towed to the Honda dealership where they could not diagnose the issue. They said the alternator was fine and the battery charged up fine. So no root cause found. Then 6/26/2023 - I drove the van for an hour to the airport and back, parked it in the garage (engine off) for about 10 minutes, and the van struggled to start but did on the second attempt. Then on 7/7/2023 - my wife took the van to the store, came back home and parked it in the garage with the engine off. She came back 5 minutes later to leave again and the van wouldn’t start. The battery was drained. Now it’s sitting on a trickle charger just so I can take it into the dealer. On 7/10/23 - I had the battery replaced and the Dealer did some sort of warranty work to help and that corrected the issue. UNTIL it died again On 11/27/23, I had to get yet again another battery as the same issues began happening and it was deemed a “bad battery”. Throughout 2024 and now into 2025 I continually have the same issues where the vehicle will stutter but still managed to kick back on after an auto shutoff. I have been to the dealer countless times and they continually tell me there isn’t anything wrong. Something is happening that causes this - whether is an electrical parasitic drain or something else. I have heard that other vehicles this has happened to but Honda claims nothing. I also had a case opened with Honda on this that never went anywhere - Case #13952151 There is clearly something wrong and not being able to diagnose it is even more frustrating given the issue. If it drains while driving - I CANNOT DO ANYTHING. I can’t even put it in Neutral to move it manually because everything is electronic!!

I am filing this complaint regarding a serious safety defect that persists in my Honda vehicle following Honda's PGM-FI Idle Stop software update. Recently, I experienced a dangerous incident on [XXX] outside Washington, DC. My vehicle completely stalled in heavy traffic, leaving me unable to start my car on the highway. The vehicle would not restart for approximately one minute, creating a significant safety hazard as traffic moved around me. Of particular concern was that during this incident it is not clear whether or not the airbag system would deploy since the car was off. This is a major safety issue and, reviewing complaints online, I am not the only customer to experience this, despite having received the software update. This is not an isolated incident. The vehicle's auto start-stop feature continues to malfunction, repeatedly shutting down when it goes into idle. This issue is also causing significant battery drain, making the vehicle increasingly unreliable and unsafe to operate. Worse, Honda indicates that this feature can act up when the battery is low, but the feature itself drains the battery. You can turn the feature off every time you get in the car, but this is not a fix. I have been informed by Honda there is no way to permanently disable the feature. I strongly urge NHTSA to investigate this matter. The current recall repair has proven insufficient to resolve the safety defect, and the malfunction creates unacceptable risks for me and my family. This issue requires immediate attention to prevent potential accidents and ensure the safety of all road users. Please require Honda to implement a repair that allows consumers to permanently disable this feature. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

It happened twice this month already. Once while driving, the car lost power (as if engine was never turned on), and the gear changed to N so I tried to slow down, then the power came back on, and then I was able to shift to D and continue my trip. Second one happened this morning. It was on auto-shutting idle position and when I put my foot on the accelerator, it completely lost power again (I recently changed the battery and tested in the afternoon and all working properly).

Several times over the last 18-24 months my van has 'stalled' after the auto engine start/stop feature restarts my car. This has mostly happened while at stop lights/signs, or idle. However, it has happened twice while driving, my car will just die and slow dramatically. I have been able to restart by pushing the start/engine button. There has been two times where restarting (while idle) has not worked. Most recently it happened while at a stop light. when the light turned green I went to accelerate and the van would not move, all the dash lit up, and there was no power to the engine. It took several minutes to get the van restarted, holding up traffic and causing me panic and fear that I could be hit.

I was driving with cruise control on and a car pulled in front of me and hit the brakes. My car reacted by hitting the brakes hard and the engine tried to recover but hiccupped and lost power and engine light flashed at me. I pulled over and when I started the car again there was a rattle that would get faster if i pressed the throttle. I was able to get back on the road and the throttle rattle was still there and now it started saying engine oil low. I pulled over, checked dipstick and it was fine. Engine oil low light continued to flash, so I went to a oil change place to have them look and change the oil and they reported nothing wrong. I left and continued driving and the rattle noise was still there, engine oil low was still there. Then i heart a loud pop and griding noise, lost all power and had to pull over. This time the car was dead. I had it towed to a mechanic who said had to be an internal defect in the engine from the factory.

On multiple occasions, after stopping the vehicle (for example at a red light), the engine would stop and not restart. After several minutes of frantically trying to restart the vehicle in dangerous situations (stopped in the middle of traffic and nearly rear ended multiple times), the vehicle would eventually start the engine. Bottom line - when stopping at a stop sign or red light, the vehicle turns off the engine and does not restart properly - placing all occupants in a dangerous situation.

The Auto-Idle Engine system malfunctions constantly. For example, several times I almost got into dangerous or possibly fatal accidents- I was in stop and go traffic on an interstate. Traffic slowed to a stop. I held the brake. The engine idled. I took my foot off the break and moved it to the gas when the traffic abruptly restarted. The car stalled and shut down. The cars around me expected me to go and had to swerve around me while I desperately tried to restart. There is no way to set a default that the auto idle feature is off when I start the car. I have to remember to turn it off. This also happened at an on ramp with a stop light, I almost got rammed by the car behind me. This feature is a drain on the engine and battery and is dangerous when it is not working correctly. The default should be off or just not have it at all. Honda dealerships aren’t willing to help me.

I have a concerning noise from my car's engine that I’ve already brought in for diagnosis. Knocking/ticking/rattling noise on stand-still acceleration at relatively low speeds/under light load. Does not duplicate when revving in park, only under light load. Sound present with HVAC on or off. Does not make noise when cold or after long trips. Honda seems to be aware of this issue and has remedied it through work involving the crankshaft bearings and possibly other components as it relates to their service bulletin 23-097. The problem is that my vehicle falls outside of the stated range of production years as mine is a 2020 model year, but the likelihood seems quite high that the engine in my vehicle is suffering from this exact problem. The service department refuses to help me and the corporate line I've contacted through email me simply refers me to the service department. I just spent $38,000 on this vehicle with 30,000 miles and I have no other recourse at this point to remedy this.

The auto idle feature cuts out the engine in stop and go traffic and will not restart. This has happened on numerous occasions, creating unsafe conditions for traffic.

Idle stop caused engine to stall 3 separate times leaving me stranded in busy intersections making it difficult to restart vehicle and move safely out of the way. Initial start up checks come on, asked to put car in park, step on brake to restart car, car won’t restart. Once happened at night and shut off all my lights for 30 seconds making me not visible for cars coming up to me.

While stopped in preparation to make a left turn across traffic on a 4 lane road, our 2020 Honda Odyssey engine stalled- the engine idle stop function did not restart the engine as designed. We had to restart our car, but the car did not immediately restart, it took us 2-3 attempts. There was no prior warning or indication there was a problem. We could have easily been hit by another car, injuring my wife and children. Our system is available for inspection, we have not had it inspected yet.

My vehicle has the engine idle option and shuts the engine off when idle in traffic or at traffic lights, etc. There have been incidents where the engine doesn't just shut off but it powers off the entire car and doesn't want to turn back on. My battery is fine because i just had service done on it and they tested the battery and its 100% fine. This issue is not a battery issue for my car. I literally had PTSD when the car shut off though because it happened at a location on the roadway where i had previously been rear ended in another vehicle and after my car shut off this time - my anxiety was very high that day and i was literally shaking. I was scared not knowing what was wrong with my car.

Vehicle driver side sliding door has issues closing. Mentioned to dealer, but dealer dismisses it as possibly from water residue after car washes. Door needs to be manually closed with pressure to latch. Vehicle has lost all electrical function while in Economy mode while in idle mode while at red lights and also while parked with accessories running. Vehicle batter life was verified and in excellent condition at battery replacement shop.
