2024 Acura ZDX brakes problems

My daughter was driving on the freeway when traffic ahead suddenly slowed. The vehicle issued a forward collision warning approximately three seconds before impact, and she immediately attempted to brake. She reported significant brake pedal pulsation and resistance while attempting to stop. Dashcam footage shows the vehicle's displayed speed decreasing from approximately 49 mph to 44 mph before impact. Additionally, the automatic emergency braking system did not appear to intervene as expected. I recently discovered the federal safety agency Engineering Analysis EA26006, an active investigation involving the 2024–2026 Acura ZDX and potential braking system failures, including reduced brake assistance and extended stopping distances.

2024 Acura ZDX Type S displayed “Service Brake Assist,” “One-Pedal Driving Unavailable: Use Brake for Stopping,” and “Auto Hold Unavailable” simultaneously at 5995 odometer miles. An electronic ticking or clicking sound occurred from the brake-control area and the vehicle experienced a jerking sensation when coming to a stop. This noise originates from under the dashboard near the steering column and suggests a possible malfunction in the braking or electronic control systems. The warnings cleared after the vehicle was shut down and restarted several times. This VIN previously had DTC C2A22 and brake operating simulator-related warranty repairs but this issue has persisted after being inspected by Acura and confirming that all braking systems systems check out.

The braking system does not engage properly and is worse in the rain. When adaptive cruise control is on, the car does not slow down at every instance when there is a car in front slowing down. When the car finally realizes there's an object/car in front it then slips before engaging in traction control, which seems to make the car actually slide forward rather than attempting to stop immediately.

My 2024 Acura ZDX has an intermittent braking-related malfunction that causes the vehicle to jerk unexpectedly while slowing or stopping. The problem has occurred in stop-and-go traffic, on hills, and while reversing. The exact cause is UNKNOWN. This creates a serious safety risk because the vehicle does not always respond smoothly or predictably when braking. In traffic, the sudden jerking could cause a rear-end collision or make it difficult to maintain a safe stopping distance. On hills or while reversing, the unpredictable movement could cause the vehicle to strike another vehicle, pedestrian, cyclist, child, or object. The vehicle has also experienced unusually rapid battery depletion, raising concern that it could become disabled unexpectedly in traffic, severe weather, or an unsafe location. Any relationship between the battery issue and the braking problem is UNKNOWN. The vehicle has been taken to authorized Acura dealerships multiple times, including Acura of Westchester and Curry Acura. The condition was reported repeatedly. The dealers stated they could not duplicate it, even after an extended road test of more than 300 miles. No permanent diagnosis or repair was provided, and the problem remains unresolved. Acura/American Honda was notified and opened a corporate case. There were no consistent warning lights or dashboard messages before the incidents. Because the malfunction is intermittent and may occur without warning, I cannot predict when the vehicle will jerk or fail to stop smoothly. No crash or injury has occurred, but I believe this defect presents an unreasonable risk of collision and pedestrian injury. The vehicle is available for inspection upon request.

This is the most recent time that the automatic brake on my car kicked in for no reason. It has happened several times and I have made Acura aware of it, but this is the first time it has almost caused an accident because the car behind me almost rear-ended me. A Similar incident happened last year and I brought it in and they did nothing since they could not replicate it. I let the dealership know that there is a recall associated with this and they said that my VIN number does not match any recalls. I made it very clear to them that it is a safety issue and that it needs to be looked into in more depth in the only response they gave me was that sometimes the automatic brakes can be triggered by items that look like bicycles or people. In this case, there was a car in front of me and a car behind me, neither of which look like a bicycle or a person. It happened so quickly and so suddenly that I am not sure if any lights came on. The Acura client relations team so far has not been able to get a hold of a manager at the dealership and this remains unresolved.

My husband was driving on a small road and we were going about 25mph when he tapped the brakes the car jumped forward and the brakes did not catch. We lunged forward almost crashing into another car. No warning lights appeared. Driving conditions were normal, dry roads. Brought it into the dealership again for the same issue that we brought it in for less than 30 days ago.

I’m reaching out regarding a serious vehicle incident that occurred in September 2024 involving my 2024 Acura ZDX. The vehicle i am leasing, accelerated forward into our property under circumstances that remain unclear and crashed into our garage, tearing down approximately half of the structure. During the event, the vehicle struck my girlfriend, causing her to sustain significant injuries, including a fractured femur, fractured tailbone, and a T12 compression fracture. There are several concerns regarding potential failure of vehicle safety systems, including lack of automatic emergency braking activation and no emergency call initiation. The vehicle remains in my possession and has not been repaired. I would like to explore whether a mechanical defect, unintended acceleration issue, or safety system failure may have contributed to the incident. Please let me know if you are available to review this matter. I can provide photos, documentation, and access to the vehicle for inspection.

I am reporting a safety concern involving delayed brake engagement on my 2024 Acura ZDX RWD. During normal braking, the brakes do not respond immediately. The vehicle slips and launches forward several times before braking force applies, and the traction control system activates prior to adequate deceleration. It feels like the brakes aren't catching properly. This condition occurs consistently and repeatedly, including on dry pavement, and is worse on wet pavement. It is not intermittent and does not require hard or emergency braking to occur. The delayed braking response creates a loss of braking confidence and presents a safety risk, particularly in traffic or during routine stops. I am concerned this may involve the brake control system, regenerative braking transition, or stability/traction control integration.
