2023 HONDA ODYSSEY Forward Collision Avoidance Automatic Emergency Braking Problems

I reported issues regarding egress failure and children stuck within the back seat of the van, Electronic Dashboard failing while driving, and no start issues amongst others (11709419). Previously the certified dealer stated the issues just could not be reproduced, despite my videos, however, today they stated a Honda admin level director showed and told them the issues are being reported by others, they dont know how to fix it, and I need to come get my car, continue driving it.

My 2023 Honda Odyssey Elite has recurring, intermittent safety-related malfunctions across multiple systems. The most serious issues are: (1) door lock/unlock and rear door opening failures preventing emergency egress (children trapped), (2) intermittent “no-start/no-response” where push-button start does nothing (no click/no crank and sometimes no lights/electrical response), and (3) intermittent dashboard/instrument/electrical abnormalities while driving. I also previously experienced dangerous driver-assist behavior including unintended automatic braking and lane/steering behavior in construction zones. Door/egress: Rear doors sometimes will not open from inside or outside even when the vehicle audibly indicates it unlocked. I have video of my children unable to exit the back seat. This is an emergency egress hazard. No-start/no-response: Multiple events where the vehicle appears electrically dead and will not start, then after waiting ~10–30 minutes it starts without a jump. Stranding hazard. Recent examples: 12/31/2025 – doors would not open initially; after entry, no lights/electrical and start button produced...

This is regarding the Collision Mitigation Braking System (CMBS) I will be driving on side streets around town (driving kids to school and daycare) and there will be no vehicle/obstacle near me/ in front of me and my van will flash on the dashboard "brake" and then it slams on the brake. This has happened at least 5-6 times as of todays date 5/20/25. There is no warning or reason for the car to brake like this. I have brought this to the Honda dealer two times now once I realized how serious this was. I was informed that since it isn't throwing a code there is nothing they can do. This is a serious safety risk not only to myself but to my children- this is a van so most people who drive this have small children. The last two incidents i was inches from being rear ended with...

The present complaint alleges as follows: 1. Honda has a defective design in the Advanced Driver Assistance Systems (ADAS) of all Honda Odysseys, models 2018-2023. 2. Namely, Honda has placed the RADAR behind the large HONDA emblem on the front grille. This causes the radar to give a "RADAR OBSTRUCTED" warning, which disables all Advanced Driver Assistance Systems in the car (Automatic Emergency Braking, Adaptive Cruise Control, Forward Collision Warning). 3. The "RADAR OBSTRUCTED" warning cannot be reset by restarting the vehicle or disconnecting the battery, requiring recalibration of the RADAR at the cost of $800 each time since it takes several hours to do (per Dealership). 4. The official Honda Odyssey Forum online has countless complaints on the same issue without resolution by Honda. 5. Honda has acted in bad-faith towards their customers since this defect impacts the vehicle's advanced safety features for which buyers incur additional expenses, endangering...

I was driving on the freeway at approx 65mph with no cars around me when the orange light that said brake came on and the car slowed down on its own. Could not override problem for a few seconds.

I wish to express my deep concern regarding the ongoing safety issues with the car I purchased in December 2022. Since April of the following year, I have repeatedly experienced heightened noise and vibration originating from the rear wheels. Despite numerous visits to the Honda 385 dealership and their assurance that they have documented and forwarded the concerns to Honda representatives for review, resolution has remained elusive. Regrettably, after an extended period of waiting, I was informed on February 26th, 2024, that the issue has been declined. This decision is profoundly troubling, particularly considering the potential safety implications. It is evident that a new car exhibiting such significant damage to the wheels, accompanied by pronounced noise and vibration, poses a serious safety hazard, especially during highway driving conditions. The persistent nature of these issues underscores the urgency of addressing them promptly and comprehensively. As a conscientious consumer, I cannot in...

Forward Collision Warning in conjunction with Emergency Braking have major safety issues that need to be addressed. 1st occurance: Driving through a construction zone through cones for lane realignment, van suddenly applied brakes in heavy traffic despite no obstacles in vans path. Vehicle quickly recovered. 2nd occurance: Driving on a dark street, van heavily applied brakes despite no obstacles. The braking occurred rapidly and van nearly came to a stop. Attempted to press harder on gas to override system with zero results. Had I been on a busier street, it would have resulted in a vehicle crash. This is a major safety issues that needs to be addressed by Honda with a recall.

The automatic emergency braking system will apply the brakes and try to slow or stop the car when there is nothing in front of the vehicle. This could cause a car following to hit my vehicle because they would not expect my vehicle to suddenly slow or stop. The service center at my Honda dealership was told of the issue and said this was normal. They did not think the system needed to be looked at. The vehicle does not have any warning lights or messages. When the brake is applied my the vehicle the dash indicates that the brake has been applied.

Driving with nothing in lane in front of vehicle brakes are applied. This has occurred several times.

Driving down the highway with cruise control and lane keep on, the vehicle engaged the breaks for now apparent reason. I immediately disengaged cruise control and applied the accelerator. So far has only happened one time.
