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.

I am reporting repeated unintended automatic emergency braking in my 2024 Acura ZDX. The vehicle was leased new on April 9, 2025 and currently has approximately 9,500 miles. The system involved appears to be the Forward Collision Warning/Automatic Emergency Braking system and related braking controls. The vehicle is available for inspection upon request. On September 14, 2026, while driving at less than 25 mph, the forward collision warning suddenly activated even though there was no pedestrian, vehicle, or other apparent obstruction requiring emergency braking. Immediately after the warning, the vehicle automatically applied the brakes abruptly. The sudden braking caused the driver to be thrown forward, and she experienced neck pain afterward. This is not an isolated incident. The vehicle has experienced similar unintended collision warnings and/or automatic braking events multiple times and at different speeds, including at higher roadway and freeway speeds. These events create a serious safety risk because sudden, unexpected braking can cause the vehicle to be struck from behind, can cause injury to the occupants, and could potentially cause the driver to lose control of the vehicle. The vehicle has been taken to the same authorized Acura dealership at least twice specifically for this unintended braking problem. The dealership has performed software updates or other software-related service in an effort to correct the problem, but the unintended braking has continued. The vehicle has been presented to the dealer multiple times for this specific complaint and repair attempts were made. Acura has now been notified directly of the continuing safety problem and has opened a case. The vehicle is being made available to the Acura dealership again for inspection and diagnosis. There were no warning lamps or messages indicating a malfunction before the most recent event.

The contact stated that while in reverse(R), the rear-view camera became inoperable with a red or yellow caution sign displayed on the screen. Additionally, the contact stated that while the vehicle was in reverse(R) on several occasions, the electric side mirrors rotated down, and the driver could see objects and other vehicles behind the vehicle. The vehicle was taken to a dealer, and the contact was informed that a software update was needed. The software update was performed, but the failure persisted. The vehicle was diagnosed another time, and it was determined that the rear-view camera and an unknown part needed to be replaced. The vehicle was not repaired. The contact stated that on one occasion, after the dealer visit, while in reverse(R) with the rear-view camera displaying a blank screen, the vehicle reversed into another parked vehicle. The contact had to physically turn while reversing, but did not see the vehicle. There was no injury sustained. A Police report was not filed. The other vehicle sustained minor damage.

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 A-Spec is impacted by the federal safety agency Campaign Number 26V112000 (blank instrument panel/rearview camera). I took the vehicle to the dealership for the recall software update. The service invoice explicitly states: 'software update due performed software update on vehicle A11.' However, the update did not actually apply. The A11 module update is supposed to transition the infotainment system from Android 12 to Android 14 to resolve the safety issue. My vehicle is still stuck on Android 12, and Acura has incorrectly advised me that my trim does not get the update. The dealership's diagnostic tools are falsely reporting that the A11 safety recall update was successfully completed when it has not been, leaving my vehicle's camera and instrument panel vulnerable to failure. I have attached the service invoice as proof of the failed repair attempt. I have contacted Acura Customer Relations multiple times and advised that the recall is not complete. They have marked the recall update as complete.

On [XXX] at approximately 700 miles on a 2024 Acura ZDX A-Spec AWD (VIN [XXX] ), the Collision Mitigation Braking System (CMBS) failed to engage during a collision event. The system did not provide forward collision warning and did not initiate automatic emergency braking before impact. The collision resulted in minor damage to my vehicle. There were no injuries. CMBS is a manufacturer-installed automatic emergency braking system designed and marketed as a primary collision-avoidance safety feature; its failure to engage in an impending-impact scenario is a safety-critical defect. This CMBS failure is one of multiple safety system defects on this vehicle. Beginning at approximately 200 miles, the rear Advanced Driver Assistance System (ADAS) developed progressive failures, including: Rear Cross Traffic Alert and Rear Park Assist intermittently non-functional Blind Spot Monitoring failures on both left and right sides (DTCs U197A-00 confirmed by independent pre-repair diagnostic scan) A stress-cracked rear parking sensor housing A factory wiring harness routed incorrectly from the vehicle side, causing mechanical tension on the rear parking sensor connector and mounting bracket (confirmed in writing by the Acura dealer service manager on Repair Order [XXX][ dated February 25, 2026) American Honda Motor Co. (AHM) refused to honor the factory warranty, asserting without supporting forensic evidence that the defects were caused by an unspecified "outside influence" or "third-party repairs." I pursued and won binding consumer arbitration through the National Center for Dispute Settlement (NCDS Case [XXX]). On March 30, 2026, the arbitrator ruled that AHM had not met its warranty obligations and that no proof of any outside influence had been offered. The arbitrator ordered AHM to perform warranty repair of all the affected safety systems plus reimbursement of a diagnostic fee. AHM has not complied with the binding arbitration award.

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.
