2024 Acura ZDX

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.

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.

On Sunday, February 15th at approximately 9:00 AM EST, I took my vehicle to Wash Co Car Wash (1020 Dolsontown Road, Middletown, NY 10940). This was the first and only time I have taken this vehicle through a car wash since beginning my lease in July 2025. It is important to note that this specific car wash is one for which my local Acura dealership provides service coupons during routine maintenance visits. As a loyal Acura customer, this reasonably implied that the facility is appropriate and safe for Acura vehicles. While inside the automatic wash tunnel, the roof-mounted shark-fin antenna assembly detached completely. There were no prior issues, no visible damage, and no warning signs before entering the wash. The following day, February 16th, I brought the vehicle to my local Acura dealership for inspection. After diagnostics, I was presented with an estimated $1,700 repair cost. This incident is particularly concerning because it is not the first issue I have experienced with this vehicle. Since beginning my lease in July, I have brought this ZDX to the dealership for service on three separate occasions to address different concerns. For a vehicle that is less than a year into its lease term, this pattern of service visits raises legitimate concerns about quality, durability, and reliability. Given the severity of the cost and the nature of the failure, I contacted Acura Client Relations in an effort to resolve the matter directly and professionally. After more than 48 hours, I was assigned a case manager named Lisette, who declined to provide her last name when asked. During our conversation, I found her demeanor dismissive and unwilling to meaningfully investigate the concern. The resolution I was given was that there is “no defect” and that the failure was effectively my fault.

Acura EV app does not sync. Not only for those who purchased the car used, but those who updated the app.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The failed component is the drive motor inverter cooling system, specifically the drive motor inverter cooler (OEM part number 87821986). This component is responsible for regulating temperature within the high-voltage electric drive system. The vehicle is currently at the dealership with the repair order open, and the part has not yet been replaced due to national backorder status. The vehicle and failed component are available for inspection upon request. 2. How was your safety or the safety of others put at risk? The failure triggered a “High Voltage System Warning” message. This warning indicates a malfunction within the electric propulsion system, which controls vehicle movement and power delivery. A malfunction in the inverter cooling system can lead to: Loss of propulsion Sudden power reduction Vehicle shutdown while driving Potential overheating of high-voltage components Because this is a $75,000 electric performance vehicle with only approximately 5,100 miles and four months of ownership, a critical high-voltage system failure creates a serious safety concern. I do not feel the vehicle is safe to operate, and I have refused to drive it under these conditions. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The issue was diagnosed and confirmed by an authorized Acura dealership service department on January 29, 2026. The dealership determined that the drive motor inverter cooler requires replacement. The repair order remains open because the required OEM part is on national backorder with no confirmed ETA. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle has been inspected by the authorized Acura dealership service department. The manufacturer, American Honda/Acura, has been notified through a formal customer relations

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.

Acura TSB 25-033 details how dealerships or independent shops should update the infotainment unit (a11). When followed correctly, the update causes the infotainment unit to fail. This leaves the vehicle with no hands-free safety and GPS functions, in addition to no radio. Acura cannot replace the radio unit, rendering hands-free safety features useless.

I am submitting this complaint regarding a significant safety-related failure in my 2024 Acura ZDX that occurred immediately after a dealer-installed software update. After my vehicle received a software update performed by an authorized Acura dealership, the entire infotainment system became inoperable. I was subsequently informed that the update caused a complete failure of the unit and that full replacement of the infotainment module is required. As a result of this failure, the following systems are nonfunctional: Hands-free Bluetooth (unable to make or receive calls legally and safely while driving) Audio/radio system Navigation system Climate control interface (controls integrated into the display) Phone charging capability The loss of hands-free Bluetooth functionality presents a direct safety concern, as drivers are required in many states to use hands-free systems while operating a vehicle. Additionally, the inability to access navigation and certain vehicle settings increases driver distraction. The climate control integration within the infotainment display further compounds safety concerns. These systems were fully operational prior to the dealership performing the software update. A routine manufacturer-issued update should not result in total system failure requiring hardware replacement. I am concerned that this issue may represent a broader defect affecting other vehicles equipped with the same system. I request that this incident be reviewed for potential safety implications and possible investigation.

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 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.

The contact owns a 2024 Acura ZDX. The contact stated that while driving 35-40 MPH and depressing the brake pedal, the brake pedal went down to the floorboard, and the vehicle slightly responded, causing the braking distance to be extended and the vehicle drove through the red traffic light before stopping. There was no warning light illuminated. The contact was able to continue driving. The dealer was contacted, and an appointment was scheduled for a diagnostic test. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 11,000.

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)

While moving about 40mph, the emergency brake engaged and it slowed car down significantly. However, there was nothing in front of me. I turned emergency braking off due to this issue. Also, during raining day, when backing out of driveway, car's emergency brakes engaged. This happen twice.

When backing up the car will slam on its brakes when there is NOTHING behind me. Most of the time it is when I am backing out of my driveway it will do it 2-3 times when nothing is there. It has done it a couple of times backing out of a parking space when nothing is there. I reported this to Acura but they didn’t do anything about it.

When hard braking the car doesn’t stop, you can feel the wheels lock up and it slides forward. Some times when stopping at slow speeds the car will lunge forward. I almost hit a car, went in an intersection and one time almost hit a person and I was only going 5-10 mph that time and I hit the brakes and the car slid forward. I am really scared and Acura says they test drove mine and a new one and they both do it so there is nothing wrong with it.

I was driving my 2024 Acura ZDX at approximately 50 mph on a rainy day and activated the rear windshield wiper. Upon activation, the rear wiper assembly detached from the vehicle and flew off while the vehicle was in motion. Fortunately, there were no nearby vehicles at the time; however, the detached wiper could have struck another vehicle or created a road hazard. The failure also resulted in loss of rear visibility during inclement weather. I contacted the authorized Acura dealer immediately. The dealer declined to inspect the vehicle or perform a warranty repair, stating that they could not proceed because the detached part could not be produced. The part was lost as a direct result of the failure. I provided photographs showing the location on the vehicle from which the wiper detached. The incident occurred less than six months after purchase, with fewer than 2,000 miles on the vehicle. I then contacted Acura corporate support. After an extended review period, Acura offered only a partial “courtesy” discount rather than a warranty repair for what appears to be a safety-related defect. I am reporting this incident due to the risk of detached exterior components becoming road debris and the associated safety hazard to other motorists.

The forward collision warning and forward collision braking malfunctioned several times triggering false warnings and unnecessary hard braking. My safety was put at risk because the vehicle came to an abrupt, violent stop while in traffic and applied the parking brake. This action not only caused items in my vehicle (e.g., phone, water bottle, sunglasses) to fly to the front of the car and land in the footwells, but also hurt my neck and head from the severe and harsh movement. Additionally, this sudden unpredictable full stop creates a very high risk of the vehicle following me rear ending my vehicle, resulting in further injury and property damage. The problem has not been reproduced or confirmed by a service center as I have not had time to bring the vehicle in for service yet. The vehicle or component has not been inspected by the manufacturer, police, or insurance representatives. There were not any warning lamps, messages or other symptoms of the problem prior to the failure. However, the emergency brake warning has triggered several times without activating the brakes.

Multiple times, while both reversing and driving forward, the vehicle has initiated hard emergency braking maneuvers when no emergency exists -- no rear or front cross traffic, no pedestrians. This is dangerous and could initiate a crash with other cars following the vehicle.

The automatic rear braking system on my 2024 Acura ZDX engages unexpectedly and without cause. It happens regularly when reversing, even though there are no obstacles, people, or vehicles behind the car. The sudden braking is jarring and creates a real safety concern, especially in traffic or tight spaces. I took the vehicle to my local Acura dealership, but they had no information or guidance on the issue. Despite this, many other ZDX owners are reporting the exact same problem on forums like Reddit, AcuraZine, and Facebook groups. This is clearly not an isolated incident and should be investigated immediately. The system is too aggressive and unreliable in its current state. It poses a risk of causing accidents or injuries. Acura must address this issue with a software update or recall before someone gets hurt.

The following diagnostic tip was issued by the NHTSA for the Cadillac Lyriq (same vehicle as Acura ZDX): PIC6537A The Acura ZDX has the same issue and there are multiple forum posts online. However Acura dealers are claiming there is no bulletin / fix from Acura. The AC compress which also functions as a heat pump vibrates and shakes the entire vehicle. This system may be responsible for battery temps as well, Im not sure. If that is the case it is very important so battery temps are regulated and fires don't happen.
