2025 Lexus RZ 450ERecalls, problems, MPG & safety

“While operating my 2025 Lexus RZ 300e at normal road speeds, the vehicle experienced a sudden and dangerous propulsion loss when the traction battery reached 0% state of charge. The only advance notice was a single soft audible alert. There were no escalating warnings (visual or audible) and no meaningful low-battery reserve to allow the driver to safely exit traffic or reach a charging location. Within seconds of the single alert, the vehicle entered reduced-power “limp mode,” creating an immediate traffic hazard. This abrupt reduction in speed occurred in active traffic among large trucks, putting my safety and the safety of other road users at serious risk. The lack of progressive alerts and absence of a usable reserve buffer prevented any safe corrective action and increased the risk of a collision or injury. Lexus marketing materials, sales claims, and the owner’s manual indicate that the RZ’s battery management system provides intelligent, progressive warnings and adequate reserve energy to prevent drivers from being stranded. My vehicle did not perform in accordance with these stated safety features. This represents a potential defect in the warning…”
