2024 Acura Zdx

I am submitting this complaint regarding serious safety issues with my vehicle. After a recent 180-mile trip, the car initially functioned without issue during local driving. However, on the morning of February 16, 2025, I encountered multiple warning messages at startup, including "Service Brake Assist," "One Pedal Driving Unavailable, Use Brake for Stopping," and "AUTO HOLD Unavailable." These warnings indicate potential braking system failures, which raise major concerns about the vehicle’s safety and reliability. Additionally, several key safety features became inoperable, including Adaptive Cruise Control and Acura Watch 360 (Supercruise). These features are critical for safe highway driving, and their unexpected failure compromises the vehicle’s performance and driver assistance capabilities. The fact that these systems became nonfunctional without warning creates a hazardous driving condition. Further compounding my concerns, the vehicle emits an electric, clicking sound when the brake pedal is depressed. This noise originates from under the dashboard near the steering column and suggests a possible malfunction in the braking or electronic control systems. Given the nature of these warnings and the potential risk of brake system failure, I am deeply concerned that the vehicle is unsafe to drive. I am seeking immediate resolution and will be bringing the car in for service as soon as possible. I urge the NHTSA to investigate these issues, as they pose a significant risk to drivers, passengers, and others on the road. Please advise on any next steps or potential recalls related to these failures. Thank you for your attention to this matter.

The parking brake continously engages when in reverse disabling the vehicle until you manually release it. This happened 6 times and I was not able to safely back out of a parking lot and had to call for a tow truck to take vehicle to dealership. Dealership scanned vehicle for codes but could not find an issue and told me that is part of the safety features. Not sure how safe it is to engage the parking brake 6 times and cause my vehicle to be in traffic. There were no obstructions around the car, so I feel this is a very dangerous malfunction.

The contact had received a 2024 Acura ZDX loaner vehicle from the dealer. The contact stated that after backing into the driveway, pressing the park button, activating the electronic brake system, and exiting the vehicle, moments later the electronic braking systemwas deactivated, and the vehicle began to roll down the driveway. The contact was able to re-enter the front seat of the vehicle and press the brake pedal to stop the vehicle. The cause of the failure was not yet determined. Upon returning the vehicle to the dealer, the dealer was informed of the failure. The manufacturer was not contacted. The failure mileage was 3,700.

The contact owns a 2024 Acura ZDX. The contact stated that while depressing the manual regenerative brake lever the braking system failed to activate and the driver had to depress the brake pedal to stop the vehicle. The contact stated that during the failure the message "Service Brake Assistance" was displayed. The contact stated that the BRAKE Hold feature and Adaptive Cruise Control were inoperable, and there was a ticking sound while depressing the brake pedal. The vehicle was taken to the dealer who reprogrammed an undisclosed software, but the failure persisted. The vehicle was returned to the dealer. The manufacturer was notified of the failure. The failure mileage was 320.

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.

I am writing to formally report a recurring and potentially hazardous issue with the Reverse Automatic Emergency Braking (AEB) system on my 2024 Acura ZDX EV. This malfunction significantly impacts the safety and usability of the vehicle. Specifically, the reverse AEB system frequently engages unnecessarily, applying phantom braking even when there are no obstacles behind the car. This issue occurs repeatedly—at least 3 to 4 times—every time I attempt to reverse out of my driveway. As a result, it is nearly impossible to back out into a busy street safely. Although the AEB feature can be manually turned off, it reactivates automatically with each new ignition cycle, creating an ongoing problem. The constant need to disable the system is inconvenient, and forgetting to do so exacerbates the safety risks. Additionally, I have observed that this issue is not isolated to my vehicle. Several other Acura ZDX 2024 EV owners have reported similar problems, as evidenced in online forums and community discussions. I have contacted the dealership regarding this matter, but a permanent solution has not yet been provided. Given the frequency and severity of this issue, I am concerned for my safety and that of other drivers. I urge NHTSA to investigate this matter thoroughly and take appropriate action to ensure that Acura addresses this defect promptly.
