2023 Lexus RZ Powertrain & Transmission Problems

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.

The contact owns a 2023 Lexus RZ 450. The contact stated that while the vehicle was in park(P), the vehicle failed to shift out of park after multiple attempts. The vehicle eventually shifted into drive(D) and as the contact began to drive the vehicle, the vehicle began to hesitate as the brake warning light appeared on the instrument panel. Once the contact reached her destination and parked the vehicle, she attempted to straighten out her vehicle as the tail end was sticking out in the road. While straightening the vehicle, the brake warning message returned on the instrument panel as the vehicle then surged forward at a high rate of speed. The vehicle ran over four garbage bins before crashing into a parked vehicle. The air bags deployed upon impact. The contact attempted to exit the vehicle after the crash but all the doors failed to unlock from the inside. The contact screamed for help as neighbors heard the commotion outside and assisted the contact out of the vehicle. Police were called but no assistance arrived. The contact did not sustain any physical injuries and did not seek medical attention. The vehicle was towed to an independent mechanic where it remained in their possession. The dealer was notified of the failure but offered no assistance. The manufacturer was notified of the matter and stated that they would review the vehicle's black box. The vehicle had yet to be repaired. The failure mileage was approximately 5,400.
