I am reporting a recurring safety issue with my 2023 BMW i4 (VIN: [XXX] ), currently at 28,426 miles. The vehicle has experienced three separate incidents of unexpected and complete loss of power while driving. The first incident occurred in March 2025. The vehicle suddenly lost all propulsion without warning and came to an immediate hard stop. I was later informed this was related to a wheel-positioning sensor. The second incident occurred in October 2025. I had been told that a recall software update would resolve the problem, but the vehicle experienced another loss of power while in motion, showing the issue was not corrected. The third and most concerning incident occurred in November 2025. Multiple error messages appeared instructing me to stop driving immediately, and the vehicle again lost power while moving. A complete loss of propulsion in traffic—especially while merging or pulling into a roadway—creates a severe safety hazard because I am unable to move the vehicle out of the way of oncoming traffic. This puts both myself and other drivers at risk. BMW has acknowledged awareness of issues related to these systems during previous service visits, but the defect continues to occur despite attempted repairs and software updates. I am requesting that NHTSA investigate this matter, as repeated power-loss events pose a significant safety risk that could lead to crashes, injuries, or fatalities.

The dashboard turn signal indicators are blocked by the steering wheel unless I adjust the steering wheel to a very high position that makes driving unsafe. When the turn signals are on, there is no clicking noise like many cars have. I suggest that BMW update the vehicle software to allow the driver to adjust the location of the turn signal indicators within the digital dash display, or also include turn signal indicators in the heads-up display.

The steering wheel would suddenly become stiff (frozen or locked) during normal driving especially during turning. When it happened, I lost total control of the car causing dangerous situations on the road. A warning message appeared stating: "Changed steering effort, drive moderately and contact service center." At a BMW dealership, the problem was reproduced and confirmed. They replaced 12 Volt battery, and the car was released. The new 12 volt battery didn't help the steeling issue. After a few weeks, the steeling system completely failed. The car has to be towed to BMW dealership for repair. It was identified that the steeling issue was caused by premature failure of the BMW electronic power steering system.

The sunroof spontaneously shattered while driving on the freeway. The sun shade was closed but had it been open, the glass would have entered the cabin and potential for harm. In addition, the loud bang was a distraction and had there been more heavy traffic there was potential for accident. There was no identified object that hit the sunroof. The car was taken to the dealership for repair and inspection.

While merging onto an interstate at speed, the vehicle experienced a sudden loss of motive power and came to a complete stop in an active traffic lane. Approximately six weeks earlier, abnormal drivetrain behavior (hesitation and torque interruption) was reported to the dealer. The dealer attributed the issue to tires and recommended tire replacement. No drivetrain diagnostics were performed. Immediately following the incident, a drivetrain malfunction warning occurred. BMW remotely restricted vehicle operation to allow limited driving back to my residence. The vehicle was later towed to the dealer. BMW subsequently confirmed catastrophic electric motor failure requiring full motor replacement. The incident created an immediate risk of collision with surrounding traffic and represents a serious safety defect involving unexpected deceleration and loss of propulsion.
