2024 Honda Accord Hybrid Forward collision avoidance Problems

“I was driving the vehicle with no other vehicles in front of me, yet the vehicle hard braked as if it sensed a collision was about to occur. This happened on 08/23/2024 around 10:05 am.”

“I was driving on a highway when the engine light came on and the car immediately started slowing down even though I was pressing the gas pedal. It flashed there was a failure of the brake system, collision mitigation braking system, road departure mitigation system, hill start assist system, and adaptive cruise control system. The check battery light also came on. The car decelerated on its own with brakes engaged. I had to choice but to immediately pull over and luckily was able to steer to an off ramp and into a parking lot.”

“Driving at highway speed with cruise control active, cruise turns off and car immediately feels like manual steering and accelerator harder to push. Warning lights displayed Adaptive Cruise, lane departure and brake system, See Dealer. Exited the highway and restarted the car. Lights went off. Taking to dealer via appointment. Dealer says they can't determine whether or not there could be danger of driving the vehicle and can't get the car in for more than a week, leaving me without transportation should something go wrong.”

“Component/System: Collision Mitigation Braking System (CMBS) or related software. Vehicle available for inspection. Safety Risk: Vehicle brakes or decelerates unexpectedly during normal driving, risking rear-end collisions. Most recent incident on August 23, 2025, required override by pressing accelerator and shifting to neutral in traffic. Reproduction: Dealer could not replicate issue during May 16, 2025 visit. No diagnostic codes found. Radar and braking systems reported as “operating normally.” A second evaluation occurred after September 5, 2025, with no resolution; issue persists. …”

“2023 and 2024 Hybrid Accord vehicles liberally activate brake lights while cruise control is active under even the slightest level of deceleration creating an appearance of a “brake check” when there is no brake check. A traditional car’s cruise control, for instance when set to 60MPH allows you to depress the accelerator, speed up to 65MPH to pass a vehicle, and then release the accelerator. The car then slows down naturally and begins controlling at 60MPH. The deceleration is gentle and the brakes are not applied and the brake lights do not illuminate. …”
