Is the 2026 Lexus RX in its fourth year on the new platform and what corrections have been made?
The 2026 RX enters its fourth year on the second-generation TNGA-K platform launched with the 2023 model. Lexus used this model year to address several pain points documented by Canadian owners: the navigation system on the 14-inch screen receives a mapping update covering new residential areas in Laval, Brossard, and Toronto's northern suburbs. The rear defogger, criticized for its automatically-fixed short cycle in Quebec use (-20°C), transitions from a fixed 15-minute cycle to an adaptive cycle based on ambient temperature and windshield humidity sensor data — extending activation up to 25 minutes when needed. Bluetooth multiplexing (two phones simultaneously) is stabilized via an OTA update deployed in October 2025, resolving the random disconnections reported on 2023–2025 RX models.
