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.

On July 4, 2021, I realized that the charge port on my BMW i3 would not accept a charge plug - it appeared to be blocked. I took the car to the dealer and they informed me that the charge port had been damaged (melted) by heat from a defective charger. In addition to public charging, I had typically been using a home charger - a MUSTART Level 2 40-amp charge cable purchased from Amazon on February 4, 2019. The BMW technician requested to see the cable and it was confirmed to be damaged also. BMW attributed this incident to the charger rather than the vehicle, so the repair (over $2400) was not covered under warranty. I feel this represents a serious safety concern, as the overheated charger/charge port could have caused a fire in my garage. I have retained the parts associated with this incident, including the charge cable and the damaged charge port from the vehicle.

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 →
