Lexus RZ in the other registers
This site holds seven national and European registers. Lexus RZ is named on 2 American notices, 2 British, 2 European, 2 Japanese and 4 Israeli. Those are separate campaigns, filed with separate authorities on their own schedules.

Nothing here says any of these is this notice in another country. A model recalled in one country is often recalled in another, in different words and at a different time, and the authorities do not cross-reference each other. Reading them together is the reason this site holds more than one register.

Issue:
On certain vehicles, a software problem could cause the heating, ventilation and air conditioning (HVAC) system to enter a failsafe mode. As a result, the heater could stop working. If this happens, the windshield defroster may not work properly.
Note: This problem could cause an "EV System Malfunction" or "Drive Start Control Malfunction" message to display.Safety Risk:
A windshield defroster that doesn't work properly could cause reduced visibility and increase the risk of a crash.Corrective Actions:
The company will notify owners by mail and advise you to take your vehicle to a dealership to update the HVAC system electronic control unit software. The dealer will also inspect and, if necessary, replace the electrical compressor.

Reading this against the source
This page is what Transport Canada published in the Vehicle Recalls Database, kept as it was read. The authority publishes only its current wording; if a notice is rewritten, the earlier version disappears there and is kept here. The whole register is at /canada, and how the reading is done is set out in the method.
What the words on this notice mean — the system it is filed under, and what the filing type says about who found the fault.
This register keeps an index of its own for every maker and every year it holds: Canadian recalls on a Lexus: 109 in the register, and 656 Canadian vehicle recalls filed in 2025.
