2024 Honda Odyssey driver assistance problems

Filed Oct 29, 2026 · Driver assistance, Electrical · TX

While driving today at about 30 mph, the minivan suddenly braked on its own—despite there being no obstruction ahead—and began beeping. The word "Brake" appeared in large letters in the center of the panel, flashing, before suddenly releasing. My wife and I both suffered whiplash from the incident. There was nothing in front of the van; the only thing nearby was some cars parked on the curb along the side. My wife told me this has happened a couple of times before, and she reported it to Honda of Tomball. I'm very concerned that if we're driving at highway speeds and there are vehicles on both sides of our lane, this issue could occur again, and we could have a serious safety problem on our hands. In addition to this, we've been experiencing another issue: the van suddenly shifts into park when we come to a stoplight. This has happened three times. Yesterday they replaced the battery, but they still suspect it could be a starter issue.

The vehicle engages the emergency breaking system on its own and at random times.

While driving in normal traffic, when I come to a complete stop and keep my foot on the brake, the Auto Idle Stop system activates as designed. However, when I release the brake to continue driving, the engine intermittently fails to restart properly. Instead, it repeatedly attempts to restart, cycling on and off several times before shutting down completely. When this occurs, the vehicle becomes disabled in traffic and does not respond as expected. It can take multiple attempts and a significant amount of time before the engine finally restarts, leaving me stranded in intersections or in moving traffic. This creates a serious safety hazard because surrounding vehicles continue moving while my vehicle is unable to move. This problem has occurred multiple times under normal driving conditions and is not an isolated incident. During one occurrence, the vehicle failed to restart after the Auto Idle Stop system activated, leaving my vehicle disabled in traffic. As a result of this incident, my vehicle was involved in a collision that **damaged the front and back bumper**. Fortunately, no one was seriously injured, but the incident clearly demonstrates the significant safety risk associated with this defect. The vehicle is currently at an authorized Honda dealership for diagnosis and repair. I am submitting this complaint because a vehicle that unexpectedly shuts down and fails to restart after Auto Idle Stop activation presents a serious safety hazard. I am concerned that this defect could lead to additional crashes, property damage, or serious injuries if it is not corrected.

When driving with or without the cruise the word BRAKE appears and the van taps it breaks automatically even when there is no reason to do so. There is no vehicle in front or anything on the road to be detected. It occasionally happens when there is a vehicle in the oncoming lane, but happens more often when there are no other vehicles close enough to be detected or cause me to need to slow down. It has been happening for some time now, but I did not know how to report it.

While driving, the vehicle will suddenly jerk taking control of the steering. As similar defect has been noted on other models. Took to the dealership and they said it is the automatic gear box.

When using the sensor-controlled, automatic wipers the lane keeping assist is silently disabled when the wiper speed switches to high. There is no warning or explicit notification of this other than the dashed lane markings indicator becoming "empty". There should be some on console warning that is more substantial so the driver knows they cannot rely on lane assist steering during this time.

The camera on top of the windshield and the radar behind the grill failed and the van has less then 12,000 miles! This is a well known issue. There is no obstruction. The area is clean and clear. Totally unacceptable.

I was driving my vehicle and accelerating. My vehicle suddenly braked with no warning while I was driving. I hit my left side of my head as I was not expecting this to happen. I was nearly rear-ended/nearly caused a multi car accident. It was incredibly scary to have the CMBS go off for absolutely no reason. There was no car ahead of me or other reason for it to happen.

This complaint alleges issues with this vehicle as follows: 1. Honda has a defective design in the Advanced Driver Assistance Systems (ADAS) of all Honda Odysseys, models 2018-2024. 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 the lives of passengers. 6. Honda has acted in bad-faith towards their customers by designing a system that requires continuous and substantial expenditures without resolution because it is an engineering problem, i.e., the placement of the radar behind the large, thick plastic H emblem obstructs the radar. 7. I hereby ask that the federal safety agency investigate this issue and order Honda to offer a solution in the form of a RECALL that permanently addresses the problem. Thank you for your time and reviewing this systemic issue.
