NHTSA Complaint #11714007 — 2024 ACURA ZDX

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.
