2023 Lexus Rz

My vehicle, a 2023 Lexus RZ 450e, has been out of service for over 30 days due to an unresolved HVAC system failure affecting cabin heating. The issue significantly impacts the safe operation of the vehicle, particularly in cold weather conditions where adequate heat is necessary for driver visibility and occupant safety. Despite the vehicle remaining under the manufacturer’s warranty, the dealership has been unable to provide a diagnosis completion or estimated time of repair. The vehicle was brought in for service on February 20, 2026, and has remained at the dealership since that time. During this period, no clear resolution timeline has been provided, and communication from both the dealership and manufacturer has been limited to general status updates with no substantive progress. The lack of heating functionality raises safety concerns, especially given the vehicle’s reliance on electronic systems for climate control. A loaner vehicle has been provided; however, the extended delay without repair or replacement raises concerns about potential defects in the HVAC or related electrical systems. The inability to resolve the issue within a reasonable timeframe suggests a possible systemic defect that is affecting other vehicles of the same make and model. This complaint is being submitted to document the prolonged repair delay, lack of resolution, and safety implications associated with the loss of heating functionality in the vehicle.
