This is an electric vehicle. I experienced a sudden loss of all power while traveling on the interstate in heavy traffic. I nearly lost control of the vehicle as it would not respond to my inputs. I had to cross two lanes of dense interstate traffic to get to a safe area to pull over and it was terrifying because the car just suddenly shut down while traveling at highway speeds. The dealership that I had the car towed to did some diagnostic work and said that "EME" had failed. The EME is the main processor that controls all electrical functions in the vehicle. My understanding is that 2019 BMW i3's were recalled due to failures of the EME due to corrosion. How my car was missed in that reacall, I can't ascertain. Perhaps because my particular car has an "S" designation, so it is called an "i3S" and it slipped through the cracks on the original recall. At any rate, the failure was catastrophic; it could have caused an accident and killed me. The car lost all power at highway speeds. Please look into why the i3S was overlooked in the original recall.

Dec 6, 2024Transmission & drivetrainFuel system

The drivetrain system malfunctioned while increasing from 60 MPH to 70 MPH. The vehicle lost all propulsion mid-journey. This put myself as well as other drivers around me at risk while I coasted to a stop on the freeway. The vehicle's warning system stated: “Drivetrain Malfunction: Stop carefully and turn off engine. Do not continue driving. Call Roadside Assistance.” There are error codes that were considered by the manufacturer's nearest service center. And while certain reduction in efficiency of the High Voltage battery were identified, the vehicle was re-initialized and test-driven multiple times, successfully moving of its own power. Notably, the vehicle's battery capacity was noted to be at 70%, not below the federally-mandated capacity for manufacturer-covered repair.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2019 BMW I3 Rex verdict →
