There are 11 owner-reported driver assist & adas complaints for the 2024 Acura ZDXin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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.
While moving about 40mph, the emergency brake engaged and it slowed car down significantly. However, there was nothing in front of me. I turned emergency braking off due to this issue. Also, during raining day, when backing out of driveway, car's emergency brakes engaged. This happen twice.
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.
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.
Traveling 10-15 MPH on street when car immediately stopped/braked and message on screen said something like “forward brake assist applied” or something like that. There was ABSOLUTELY NOTHING in front of me. Thank god there was no car immediately behind me or I would have been rear-ended
When reversing out of a parking spot, a driveway or around a corner, at random the vehicle will activate reverse automatic emergency braking for no reason. Sometimes multiple times in one maneuver. This is dangerous as it leaves you stopped in the middle of a street, particularly distressing when vehicles are coming and you have to take the extra time to take off the parking brake and continue the maneuver, hoping it doesn’t happen again.
The vehicle will slam on the brakes randomly without any warning or any object even near by. It will do it repeatedly to the point where I cannot reverse out of my driveway. This is dangerous as you find yourself stuck in the middle of the road with oncoming traffic because the car keeps automatically braking every few feet for no reason. The vehicles lane keep assist also will consistently intervene for no reason to the point you are constantly fighting it while driving if it’s on.
Car will not let me reverse. I have to turn it off to let me back out of driveway. When it rains the water runs down off camera and stops car.
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.
On several occasions the car will violently stop as if we have crashed into something but there is nothing there. There is no warning before this happens even though we have the alert setting turned on. This has happened while we are reversing and moving forward. This puts us (driver and passengers) at risk because it is such a sudden and violent stop that it hurts our bodies (neck/back) and it is very stressful. It has not been reproduced or confirmed by the dealership yet
When reversing and there’s nothing behind the car , it will automatically brake hard and say remove parking brake.
