Adaptive Cruise Control problems of the 2024 Honda Pilot

Incident description: while traveling at 45 mph with adaptive cruise control (acc) active, the vehicle experienced a "phantom braking" event triggered by high-contrast shadows on the roadway. The collision mitigation braking system (cmbs) incorrectly identified a shadow as a physical obstacle and abruptly applied the brakes in a clear path of travel. I was forced to manually override the system by applying the accelerator to prevent a potential rear-end collision. Safety risk & technical context: this defect is repeatable under specific lighting conditions and occurs across multiple speed intervals (35–45 mph). I believe this incident is directly related to the ongoing NHTSA engineering analysis (ea24002) regarding inadvertent aeb activations. Furthermore, recent service bulletins (such as mc-11024251-0001) regarding front view camera and radar sensor updates suggest a known failure in the system's ability to process high-contrast environmental data. Conclusion: my local dealership failed to investigate the complaint. The sudden, unexpected deceleration poses a severe safety risk to the vehicle's occupants and following traffic. I request that NHTSA formally notify Honda of America regarding this recurring adas failure to ensure that my VIN is prioritized for the necessary sensor alignment and software enhancements.

My Honda is having strange, intermittent issues with a plethora of things. I have taken it to a diagnostic specialist who worked with a phone mechanic and noone can tell me what is going on. My car will fully shut off at stop lights randomly, so I have to turn off the auto-idle feature every time I drive. Sometimes my power steering cuts out and my wheel locks and unlocks and my computer screen shuts off when this happens. I have to shut off and start my car for it to work again. Other times, all of my automated safety features stop and I get a huge slew of messages telling me that my lane assist, automatic hill braking, and a ton of other automatic safety features don't work. My car can't lane assist, do adaptive cruise control, use the backup camera, or anything. It goes away if I stop and restart my car a bunch. I also had a seatbelt alarm that was going off repeatedly with no reason. The dealership turned off the alarm. I am having a lot of issues with this car that makes me question if it is a lemon. I see other new Pilot owners mentioning issues with power steering shutting off and it's a huge safety risk. Noone knows whats wrong or how to fix it so what do I do? this happens intermittently, randomly, and recurrently since June.

I believe that there is a safety issue with the design of the adaptive cruise control on the 2024 Honda Pilot. The vehicle applies the brakes at about 1 mph over the selected speed. It is especially aggressive when topping a hill. The gas lets up, but due to the vehicle inertia, the car slightly accelerates, then braking. I believe that this action is unsafe for several reasons. It slows the vehicle several mph below the set speed causing cars behind me to swerve or come close to me. No human driver would apply the brakes in that situation. It also appears to irritate those same drivers. I’m glad that none of them has a weapon so far. It also applies the brakes going downhill on the interstate highway. This occurs at any speed below 55 mph. This also makes it look like the driver is continually tapping the brakes, when no one normally would. I suspect that there may be extra brake wear. My family asks what is going on with the car because of the aggressive braking. I previously owned a 2018 Honda Pilot with adaptive cruise control. It used transmission downshifting to slow the vehicle. I admit that there were some over speeds, but nothing serious. The 2024 owner’s manual states that downshifting is also used, but I’ve only seen the brakes used for over speed control. There are no user selectable adjustments to the system. I am getting used to this (feature, not a bug) by clicking off the cruise control whenever the conditions are close for a brake activation. This causes me to pay more attention to monitoring for those conditions, rather than the actual driving and traffic scan. I suggest that the system use downshifting followed by brakes after a 3 or 4 mph excursion from the set speed.

1: all system warnings on to include auto lights and brake system warning (there were at least 10 warnings) - auto lights stopped working 2: car would not turn off - needed to press shut off button up to 10 times 3. Remote start started car and then would not shut off and locked us out of the car - was unable to get in with key fobs for over 45 minutes, finally used emergency key in the fob and somehow the back door opened and we climbed through to turn off car.

Today, while I was driving, the vehicle information display suddenly started flashing warnings indicating that the following systems were experiencing errors, leading to potentially reduced brake performance. I was advised to take the car to the dealer for diagnosis and immediate remediation: anti-lock braking system (abs) hill start assist lane departure and correction assist brake hold system however, when we stopped and attempted to turn off the car in the usual manner, it wouldn't shut down. It took two attempts to finally turn off the car. The indicators began flashing again when the car was restarted, but after turning off the car again and waiting for 10 minutes, then restarting it, the warning messages disappeared. I managed to take pictures of at least two warnings as they were displayed on the vehicle information screen: hill start assist and anti-lock braking system (abs). This is a brand new car, and it's concerning to encounter such issues with only 1,215 miles on the odometer. I request that the NHTSA investigate this matter with Honda’s manufacturing to ensure these problems are clarified and rectified before they lead to any accidents.
