1 Warnings problem

Failure Date: 03/15/2026

The forward collision prevention system engages the brakes when nothing/no one is in front of us. It will also engage the lane departure warning, which also engages the brakes, when construction zones remove the actual lane lines and temporary lines are put down. The car gets confused and brakes the car to a stop in the middle of a highway.

2 Warnings problem

Failure Date: 05/24/2025

2021 Odyssey exl the electric parking brake 'issue' warning comes on while driving and collision mitigation warning / lane assist switches off and flashes in console; when this happens the car continues to run but the dashboard warning lights comes up for parking brake / collision warning and or lane assist. It gets cleared after I turn on/off the car couple of times and drive for approximately 5 miles. Those features had to be turned on manually, once the car is in parked mode, again. The issue started in the car at around 48k miles. Never had any issue with it before that.

3 Warnings problem

Failure Date: 04/15/2021

While driving in highway construction zones the car's lane departure system attempted to steer the car along lane markings set before the construction zone was established. In several instances this caused my car to steer, contrary to my steering input, towards jersey barriers and dangerously close to a collision. The car's collision warning and automatic braking systems then engaged and applied the brakes regardless of following traffic. After the first instance, luckily in light traffic, I became aware of this issue and aware of how to quickly defeat these safety systems. After several additional instances, some in traffic at highway speed, I determined the lane departure system was more dangerous than helpful and I suspended it by a simple dashboard procedure. I am now able to negotiate construction zones without issue.
