On the 2025-2026 BMW iX3 Gen6 Neue Klasse eDrive, the new-generation 'Neue Klasse' iX3 (NA5) was recalled in 2026 over a manufacturing defect in the onboard (comfort) charging electronics unit that could allow voltage to be present on the vehicle body during charging, creating a potential electric-shock hazard to anyone touching the car while it is plugged in. The recall covers 145 vehicles built between 25 Nov 2025 and 20 Feb 2026 (28 of them in Germany), referenced by Germany's KBA as 16565R. BMW says the scenario is unlikely and no injuries have been reported, but affected dealer stock was blocked from delivery until repaired.
Common Symptoms
Potential voltage on the vehicle body while charging
Possible mild shock when touching the car during charging
Affected vehicles flagged for stop-delivery / recall
How to Fix
Recall remedy is complete replacement of the onboard charger unit at a BMW dealer; owners are contacted directly and VINs can be checked against the recall. Until repaired, BMW guidance is to avoid using the affected vehicle for charging.

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.
Common Symptoms
Grinding or scraping from rear brakes
Visible heavy rust/pitting on rear discs
Squealing or rumbling on the rare hard stop
Brake drag, pulling, or a hot rear wheel after driving
Rear discs condemned for corrosion at low mileage
How to Fix
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.
