2024 Acura Zdx

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 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.

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.

2024 Acura ZDX Collision Mitigation Brake System will activate without warning engaging the parking brake. Has occurred intermittently while driving forward or in reverse. Dealership claims there are no codes and has advised that both front and rear systems should be disabled. Manufacturer states there are no software updates to address this issue. Failure milage approx. 100.

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.

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.

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.

On Wednesday, [XXX], I was driving near an intersection. There was a vehicle in front of me; however, they were accelerating as was I and at approximately the same speed. For no apparent reason, the automatic emergency braking activated and slammed on the brakes for absolutely no reason. This not only scared myself, but my [XXX] daughter in the back seat, and we almost were rear-ended by the car behind us. It was almost as if I was "brake-checking" the person. Both my daughter and I complained of neck pain (almost felt like whiplash) as well as a headache following this incident. There was absolutely no warning that this was going to happen. There were no messages, lights, or any other issues at the time. While this incident has only happened one time, it has happened one time when the vehicle has less than 3,000 miles on. This can quickly become an issue of someone getting rear-ended, or potentially even a road rage situation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
