2024 ACURA ZDX

The contact owns a 2024 Acura ZDX. The contact stated while driving at various speeds, the Collision Mitigation Braking System (CMBS) activated the Automatic Emergency Braking (AEB) erroneously. There was no warning light illuminated. The contact stated that the failure occurred more frequently while reversing and occurred intermittently while driving forward. The contact stated that his wife also owned the same model vehicle, which had experienced the same failure. The contact had taken his wife's vehicle to an unknown local dealer, where it was suggested that the Forward Collision Avoidance system should be disabled. The contact had not taken the vehicle to the dealer to be diagnosed. The vehicle was not diagnosed or repaired. The manufacturer was informed of the failure. The failure mileage was approximately 200.

The contact owns a 2024 Acura ZDX. The contact stated while driving at an undisclosed speed, the Collision Mitigation Braking System (CMBS) engaged erroneously. No warning light was illuminated. The contact stated that the failure also occurred while reversing. The vehicle was taken to an unknown dealer; however, the failure could not be duplicated. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 200.

Multiple times, while both reversing and driving forward, the vehicle has initiated hard emergency braking maneuvers when no emergency exists -- no rear or front cross traffic, no pedestrians. This is dangerous and could initiate a crash with other cars following the vehicle.

The forward collision warning and forward collision braking malfunctioned several times triggering false warnings and unnecessary hard braking. My safety was put at risk because the vehicle came to an abrupt, violent stop while in traffic and applied the parking brake. This action not only caused items in my vehicle (e.g., phone, water bottle, sunglasses) to fly to the front of the car and land in the footwells, but also hurt my neck and head from the severe and harsh movement. Additionally, this sudden unpredictable full stop creates a very high risk of the vehicle following me rear ending my vehicle, resulting in further injury and property damage. The problem has not been reproduced or confirmed by a service center as I have not had time to bring the vehicle in for service yet. The vehicle or component has not been inspected by the manufacturer, police, or insurance representatives. There were not any warning lamps, messages or other symptoms of the problem prior to the failure. However, the emergency brake warning has triggered several times without activating the brakes.

The automatic rear braking system on my 2024 Acura ZDX engages unexpectedly and without cause. It happens regularly when reversing, even though there are no obstacles, people, or vehicles behind the car. The sudden braking is jarring and creates a real safety concern, especially in traffic or tight spaces. I took the vehicle to my local Acura dealership, but they had no information or guidance on the issue. Despite this, many other ZDX owners are reporting the exact same problem on forums like Reddit, AcuraZine, and Facebook groups. This is clearly not an isolated incident and should be investigated immediately. The system is too aggressive and unreliable in its current state. It poses a risk of causing accidents or injuries. Acura must address this issue with a software update or recall before someone gets hurt.
