Incident Date: [XXX] Location: Miami, FL, USA What happened: On [XXX], in Miami, Florida, I brought my 2024 Acura ZDX to a complete stop on a flat surface, applied the brake, and then selected Park (the “P” indicator was illuminated on the instrument panel). After selecting Park, I opened the driver’s door and exited the vehicle. While I was outside the vehicle and no one was in the driver’s seat, the vehicle moved backward on its own and struck another car. I did not press Reverse or command any additional gear change after selecting Park. The vehicle had been fully stopped before Park was selected. No injuries occurred, but property damage resulted. This incident created a significant safety concern because the vehicle moved while unattended after Park was selected. I am reporting this event for safety documentation and investigation.

Approximately three weeks ago, following a manufacturer-issued software update, the AcuraLink connected services app stopped functioning on my 2024 Acura ZDX. This outage has disabled OnStar-connected safety features including remote monitoring and emergency/roadside assistance connectivity and concerned there were other technology issues that may affect this, but I’m not aware exactly all of them. Additionally, none of the remote features work. This vehicle is an electric vehicle and there is no ability to monitor the status of the battery charge or to monitor the battery. Given the amount of technology in this electric vehicle the fact that the remote functions are not working presents a severe safety problem. I have contacted both OnStar and Acura customer support multiple times; both confirm awareness of the outage issue but have provided no fix or timeline. Both companies have taken no responsibility and their communication is terrible.The outage began around August 3, 2026 and remains unresolved as of August 20.

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.

Was trying to unlock the vehicle but it wouldn’t unlock the doors with the remote. Had to crawl through the trunk to access the car. Got a “door latch system service” maintenance error on the screen after the dealership had “fixed” it. This is a huge safety concern as this car is electric and if it does not unlock from the inside, can cause the passengers to be stuck in the car.

The shark-fin antenna housing on my Acura ZDX appears to have a defect in the way it is secured to the vehicle. The housing can separate from the roof during normal vehicle operation, creating a road hazard and potentially striking another vehicle, cyclist, or pedestrian. I reported the issue to Acura, but the company stated that the repair was not covered under warranty. I have found reports from other Acura ZDX and Honda Prologue owners describing the same failure. Although some dealerships have covered the repair, replacing or reattaching the housing does not necessarily correct the underlying design or retention defect. Because this component can detach from a moving vehicle and become a projectile, I believe it presents a legitimate safety risk. I am requesting that this issue be investigated to determine how widespread it is and whether a recall or redesigned attachment method is necessary.
