2024 Acura Zdx

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.

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.

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.

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.

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 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.

I am filing this complaint due to a persistent and dangerous safety defect in my 2024 Acura ZDX. Since January 2025, the vehicle has suffered from recurring heating system failures. This has happened multiple times throughout the year, each time I have had this issue I have taken the vehicle to the dealership and have documented records that are verifiable. The issue most recently occured, on January 21, 2026, the heater failed and was blowing ice cold air, during a winter with 'Real Feel' temperatures of -25°F. The manufacturer has refused mechanical repairs (claiming it is a 'software issue') and has suggested I simply 'charge the car every time I stop' to generate heat. This is an inadequate technical remedy for a life-safety issue, especially as I transport three small children. The dealership is currently demanding the return of their loaner vehicle, which would leave my family stranded in dangerous, sub-zero conditions. My vehicle meets the statutory presumption of a Lemon under the New Vehicle Buyer Protection Act because it has been out of service for over 30 business days. Manufacturer: American Honda Motor Co. (Acura) Model: 2024 Acura ZDX (EV) Defect: Complete failure of the heat pump/HVAC system in sub-zero temperatures. Mediation Start Date: April 2025 (Exceeds 9 months without resolution), I was finally assigned a mediator in December 2025 only after sending emails to Acura executives. Current Status: Vehicle is currently out-of-service at the dealership, the dealership states they are unable to replicate the issue and that I need to return the loaner vehicle. 

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.

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.
