NHTSA Complaint #11649894 — 2024 ACURA ZDX

I am writing to report a serious safety defect in my 2024 Acura ZDX concerning the Forward Collision Alert and Automatic Emergency Braking. The system exhibits hyper-sensitivity, leading to unwarranted and dangerous automatic braking events. On 3/17/25, at approximately 4pm PT, I was driving my Acura ZDX on US 101 at 65 mph. A vehicle in front of me changed lanes into my lane. There was ample space between my vehicle and the vehicle that changed lanes. However, the Automatic Emergency Braking engaged the brakes forcefully, bringing my vehicle to a complete stop in the middle of the freeway. The vehicle essentially stalled for approximately 5-10 seconds, and I was unable to accelerate or move forward during this time. This created a highly dangerous situation, as I was vulnerable to being rear-ended by oncoming traffic. This incident occurred even though I had disabled the Forward Collision Mitigation System through the vehicle's settings. The system's behavior indicates a severe malfunction or design flaw, as it overrides the driver's intent and poses a significant safety risk. The fact that the system engaged the brakes when it was supposed to be disabled is very concerning. This hyper-sensitivity and the inability to fully disable the Emergency Braking System are critical safety issues that could lead to serious accidents, injuries, or fatalities. I request that the NHTSA investigate this matter immediately.
