The vehicle was purchased brand new on Feb 1st 2024. While driving on the highway on Feb 5th 2024, with only 105 miles on the odometer, and no prior warning messages/lights, many warning messages were suddenly displayed on the dashboard, repeating one after the other, instructing that various safety features were disabled, displaying: "Parking brake not available", "Brake system problem", "Brake performance may be reduced", "Brake hold system problem", "Anti-lock brake system problem", "Vehicle stability assist system problem", "Reduced traction and handling", "Electric power steering system problem. Steering assist reduced", "Hill start assist problem. Vehicle may roll upon brake release", "Trailer stability assist system problem", "Hill descent control system problem", "Adaptive cruise control system problem", "Lane keeping assist system problem", "Collision mitigation braking system problem", "Road departure mitigation system problem", "Low speed braking system control problem", "Auto high beam problem", "Parking sensor problem". In addition, after coming to a full stop and shifting to Park, (or, turning off the car) the tailgate would not open regardless of how we tried (dash button, remote key, tailgate handle, foot swing). Also, the car would not turn off after pressing the On/Off button. The button would need to be pressed repeatedly to turn off the vehicle. All of these safety systems and functions were disabled at the same time without prior warning while driving at highway speeds. The Honda dealer confirmed the problem, inspected the vehicle, and concluded a faulty ABS control module is to blame. We know of one other 2024 Honda Pilot owner in our neighborhood who experienced the same issue, which makes it likely that this is a common problem. Honda should have designed redundancies to prevent sudden simultaneous failure of so many safety systems. Honda should recall all affected vehicles to replace faulty ABS control modules before people are hurt.

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.
