What 50 owners told NHTSA about the 2017 BMW I3

Summary On September 30, 2025, the passenger in a 2017 BMW i3 REX was involved in a severe frontal collision with a Gas Company Utility Vehicle. The impact struck the driver’s side extending toward the passenger side, causing the vehicle to spin violently and nearly flip. The passenger reports seatbelt failure with excessive slack, leading to partial ejection from the seat, mid-thigh restraint, and collision with the steering wheel. The head lodged under the steering column, resulting in loss of consciousness and a severe traumatic brain injury (TBI) with ongoing neurological issues. Only the driver’s curtain and seat airbags deployed; the steering wheel and passenger frontal airbags did not. Seatbelt Failure Analysis Seatbelts in modern vehicles like the BMW i3 include retractors and pretensioners designed to lock and tighten upon impact detection via accelerometers. Excessive slack, as described, suggests a malfunction in the pretensioner system, which failed to eliminate belt looseness during the high-G force event. This allowed forward momentum to propel the occupant, exacerbating injuries. Common issues in BMW i3 models include seatbelt twisting and retractor malfunctions, as reported in owner forums and repair services. Pretensioner failures can stem from sensor errors, mechanical wear, or manufacturing defects. In this crash’s severity, proper function should have secured the occupant, preventing ejection and secondary impacts. Airbag Failure Analysis The BMW employs a supplemental restraint system (SRS) with frontal, side, curtain, and seat airbags, triggered by crash sensors evaluating impact direction and force. Non-deployment of the passenger frontal and steering wheel airbags in a near-head-on collision indicates potential system failure. Possible causes include faulty occupant classification system (OCS) mats that misdetect presence/weight, leading to deactivation; sensor malfunctions; or wiring issues. A 2017 NHTSA recall (17V-720).

A BMW i3 caught fire in our garage. Maintenance on the car had been performed the day prior and it was found that the mechanic left the oil cap off. It took less than 7 minutes from the time the car started smoking to the point where the entire home was engulfed in flames. The fire department was onsite a couple of minutes after the car started smoking. It took 4 fire departments approximately 2 hours to extinguish this fire. A car should not be designed in a way in which an oil cap can cause the complete destruction of a home that quickly putting people’s lives at risk. The car was picked up by Geico, so we do not know if it is still available for investigation, but the fire investigators did confirm the cause was the missing oil cap. At this time, ourselves and three of our neighbors are unable to return to their homes. We are looking at least another year before being able to return. We lost everything in our home along with the car. This included many items which can never be replaced. This BMW i3 put ourselves, the neighbors and the multitude of firefighters this took to put this fire out lives at risk.
