On the 2021-2025 BMW iX3 Gen5 eDrive rear motor (RWD), because the iX3 does the vast majority of its deceleration with regenerative braking, the rear friction brakes are rarely applied and almost never reach the temperatures needed to burn off moisture and road film. Without regular heat cycles the rear discs develop heavy surface rust, scoring and pitting, and the caliper slide pins and pistons can seize. This is distinct from regen feel/behavior: it is mechanical corrosion of the friction brakes themselves. It is worst in humid climates, on coastal/salted roads, and on cars that sit parked for long periods. Owners often find rear discs need replacement for corrosion long before the friction material is worn out, and a seized rear caliper can drag, overheat and ruin a pad/disc.
Periodically perform deliberate hard stops (BMW recommends this) or select a lower/adaptive regen mode so the friction brakes engage and clean themselves; in salty/humid regions service the rear calipers (clean and re-lube slide pins, free the pistons) at least annually. Once discs are pitted/scored or a caliper has seized, replace rear discs and pads per axle and rebuild or replace the affected caliper.
On the 2021-2024 BMW iX3 Gen5 eDrive40, the high-voltage charging socket lock actuator can fail or jam, leaving the charging cable physically locked in the port so it cannot be removed, or preventing the car from starting a charge session. BMW documentation ties this to faults stored in the charging interface module (LIM), including '805532 high-voltage charging socket: lock on the charging plug, status implausible' and '805503 high-voltage charging socket: charging plug lock, line disconnection'. Causes include a non-functioning lock actuator drive, a jammed emergency-release strap, or housing tolerance preventing the lock pin from disengaging. Related door-lock/BCM communication faults can also stop a charge from initiating when the car is locked.
Try locking then unlocking the car with the key fob to release the cable; if that fails, use the manual emergency-release strap in the boot to free the cable. For a recurring fault, the dealer scans the LIM, applies firmware updates to the charging electronics/BCM, and replaces the charging-socket lock actuator (or the socket assembly) if the actuator drive is defective.
