While driving my 2016 BMW i3 with Range Extender, the vehicle experiences sudden and complete loss of propulsion at very low state of charge (0–1%). The car abruptly loses motive power, forcing me to pull over, sometimes while in traffic. After sitting for several minutes, limited power may return, but the vehicle often shuts down again, and in some cases the Range Extender engine does not engage at all. This has occurred repeatedly and creates a serious risk of being stranded or hit while merging or driving on public roads. BMW has inspected the vehicle twice (07 Nov 2025 and 13 Jan 2026) and confirmed the loss of propulsion and need to pull over but classified the behavior as “normal” without performing high-voltage battery diagnostics. The failure appears consistent with high-voltage battery voltage collapse under load, causing the battery management system to shut down the drivetrain. This is not normal power limiting — it is a sudden drivetrain shutdown that occurs without warning and poses a significant safety hazard.

My bmw i3 has a faulty wiring harness or some other defect that is causing my car to turn off the airbag system. This is a chronic issue with bmw i3’s. Either the wiring harness is bad or the airbag becomes too stiff and the car deactivated the entire airbag system. Dangerous!
