Multiple occasions the brake collision senor activates without an obstacle in site. The car would spontaneously brake as the warning sensor flashes on the dashboard. No resulting crash, but a few close incidents.
The contact owns a 2019 Acura MDX. The contact stated that while driving approximately 3-4 mph, he depressed the brake pedal but it failed to respond. The contact drove into a pole. The brake message was displayed. There was no reported injuries, fire or air bag deployment. A police report was not filed. The vehicle was towed to the local dealer but, the vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 37,000.
The automatic collision mitigation system had a complete 100% lock up of my brakes during a cross of an intersection. Although I was wearing my seatbelt the force of the stop threw my head into the steering wheel. It is a complete miracle that the car behind me did not rear-end me. This system routinely gives false positives when going around corners when you are in the center lane and it beeps and pulses the brakes. This time, the car stopped completely and I hit my head and was lucky to not cause an accident. There should be a way to 100% permanently turn off or Acura needs to fix their software. Too many false positives and actually is less safe with it on.
After vehicle powered off and and after couple of hours later, the break pedal gets very stiff. So, tremendous force needs to apply to start to engine. After around 600 miles of driving this new vehicle, this problem happened. My wife is primarily driving this vehicle. And thus she is getting knee pain issue to stiff break pedal. Acura confirmed this is known issue but they denied to fix it as indicated in the attached document.
The anti collision system is defective and it's putting my family at risk. It slams on breaks by itself without any obstacle in front. It started happening more and morr frequently. Called the Acura dealrship and they claim it's normal and the car would break for any perceived obstacle in front of it.
