NHTSA Complaint #11710076 — 2023 LEXUS RX

If we don't drive the car for 4 or 5 days, especially in cold weather, the car will sometimes not start due to a drained 12V battery. We've spoken to Lexus of Rockville, MD and Lexus roadside assistance, who are aware of the issue but say the 12V battery is "healthy." Online research shows this is a widespread known issue with Lexus RX350h and RX500h vehicles from 2023 onward: [XXX] [XXX] . A simple software update to ensure that the high-voltage hybrid battery charges the 12V battery to a greater extent when the vehicle is parked should solve the problem, but Lexus has so far not addressed this problem.
