FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS, LANE DEPARTURE: WARNING
The camera is faulty and I've brought it in once early on and the dealer said a wire needed to be tightened. It happened again and they said no such loose wire this time. The code says camera needs to be replaced. I don't even have 100k miles on this car and it's going bad. Faulty part and I know this is happening a lot.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, LANE DEPARTURE: ASSIST
Turned on the car. It was parked for 1 day after the last driving event with no issues. Today was 15 degrees hotter than yesterday. The following errors popped up on the dashboard: Adaptive cruise control problem Collision mitigation system problem Lane keeping assist problem Road departure mitigation system problem Auto high beam problem All of the advanced safety features which utilize the front camera and sensors are deactivated. Car was turned off and restarted multiple times, windshield cleaned, and car cooled down, but the warnings remain each time. This specific issue has happened 5 times over the past year. The dealer was never able to replicate the issue as it would go away as soon as the car was restarted. This time, the warning lights would not go away.

ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
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.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS, ELECTRICAL SYSTEM
The front camera has failed for apparently no reason at all. There has been no crash, no damage on our end. We turned the car on and all of the safety warnings came on. The dealership has inspected it and said the code is for the camera failing. Many warning lights appear on the dash due to none of the safety features working without the front camera. This has caused all of the adaptive safety features to fail. There have been no recalls yet, despite the recalls for the rear camera, and many other odyssey owners having the same issue with the front camera. We have reported it to honda and were told that it has been reported by others, but not enough times to issue a recall. It is expensive to fix and poses a serious danger to leave due to none of the safety features working. This is a manufacturing defect that honda is not taking seriously.

Front facing camera went out on a 2020 model. Several warning lights appear related to lane assist, front collision warnings, and automatic emergency braking. These safety features are important, and Honda should issue a recall. The camera is around $800 to replace, plus another $800-$1000 to install and calibrate. Car is only 5 years old, and there have been other camera/electrical related problems, and many recalls. Please hold Honda accountable to fix their declining reliability issues.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
1) Infotainment system crackles, pops, and shuts off frequently. Will not come on sometimes until 5 minutes into the drive, meaning we cannot use our rearview backup camera. This was recalled in other models but not our specific VIN. 2) “Shutter grill problem; power reduced” comes on randomly even when just idling. 3) Sliding doors will bounce shut or not open all of a sudden! Both doors affected similarly. Turning off the power doors does not solve the issue, so we lose access to one side. There was a recall on sliding doors for other models but not our VIN. We are taking it into the dealer to investigate but this is a safety issue.

ELECTRICAL SYSTEM, ENGINE
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

FUEL/PROPULSION SYSTEM, ENGINE, ELECTRICAL SYSTEM
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.

FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
Over 8 multiple safety warnings turned up on dashboard on many occasions while driving. Also, vehicle fails to issue a code on OBD and Honda rep claims they’ve never seen anything like this after showing them video proof of multiple occurrences. I’ve seen many complaints online. My wife drives this vehicle with young children and doesn’t feel safe while driving it because of it stating multiple safety warnings.

The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 23V431000 (Back Over Prevention); but the VIN was not included.

ELECTRICAL SYSTEM, ENGINE
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.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, LANE DEPARTURE: ASSIST
On 3/3/2025, the multipurpose camera started failing and I was seeing warning lights all tied to this system. Adaptive Cruise Control Problem, Collision Mitigation System Problem, Road Departure Mitigation System Problem, Auto High-Beam Problem, and Break System lights all came on. The problem was confirmed by the Honda dealership claiming there was an internal short that caused the issue. The component hasn't been inspected beyond this initial diagnosis. My family's safety is at risk with this malfunction in the event that we need assistance with breaking in an emergency situation, the vehicle can no longer take steps to prevent the car from drifting outside its lane and the high beams will no longer automatically turn off because the car can no longer sense oncoming traffic. Our insurance appraiser verified that this wasn't the cause of any collision, and the dealer has stated that this system should have lasted longer than expected.

ELECTRICAL SYSTEM, ENGINE
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!!

ELECTRICAL SYSTEM, ENGINE
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)
