What's wrong?
The HVAC control ECU in the 2023-2025 Rz, BZ4X, and Solterra vehicles is the electronic controller for cabin heating, ventilation, air conditioning, and windshield clearing. It reads system inputs and tells the heater, air conditioner, defroster, and defogger when to run. The defroster depends on that controller because warm, directed airflow clears fog and frost from the glass.
In recall 25V577, the problem is in the HVAC control ECU software. During an HVAC fault, including an electrical compressor failure, the software tells the system to enter a protective failsafe mode. That mode suspends heater operation, which also affects defroster and defogger function. If the windshield needs heat to clear moisture or ice, reduced defroster function reduces visibility.
There is no warning sign before failure. An owner first notices the problem when the defroster or defogger does not clear the windshield as expected during an HVAC fault.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific crossover is included.
What's the safety risk?
A defroster or defogger that does not work can leave the windshield unclear in weather or temperature changes, which decreases visibility and increases crash risk. If the glass will not clear, avoid the trip and schedule the recall repair soon. Repair is free at any franchised Lexus dealer.
What should I do?
- Check your VIN to confirm your 2023-2025 Lexus Rz, Toyota BZ4X, or Subaru Solterra is included in this recall.
- Contact a franchised Lexus dealer to schedule the free HVAC control ECU software update and compressor inspection that address defroster and defogger loss during HVAC faults.
- Bring the owner letter to the dealer, or reference recall number 25V577 and Lexus recall 25LB04 or 25LA04 when you call.
- Use extra caution in cold, humid, or wet conditions until the repair is complete, since a failed defroster or defogger reduces driver visibility.
- Call Lexus customer service at 1-800-331-4331 with questions about the recall repair.
What happens at the repair
At the dealer, a Lexus technician updates the HVAC control ECU software. The technician also inspects the electrical compressor and replaces it if the inspection shows it is needed. The software update, inspection, replacement parts, and labor are free under the recall. If you paid to fix this condition before the campaign, Toyota's general reimbursement plan covers documented expenses. Bring your repair paperwork and receipts to the Lexus service desk when you arrive.
