*Median odometer reading when the problem happened, where owners gave one. One complaint can name several problem areas.
Electrical system
The car has lost power on the highway multiple times and gone into Limp mode with no warnings on the dashboard. The Rex engine has failed to start as well. Very dangerous on the highway going 20 mph trying to make the next exit. The car has been back to the BMW dealer multiple times (over 2.5 months at the dealer ) with no repair. They are now offering to take the car in trade. The car is still under the EV warranty in California. Seems they and BMW engineering donât know how to repair the car and are now putting the burden on the consumer.

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…
Apr 28, 2026Seat belts
In early September, a "driver retention system" error appeared the dash display of my '19 i3. I searched the issue on line and tried but failed to resolve it. A few weeks later, the seat belt alarm stopped going off when the belt was clasped. At this point, I had no choice but bring it in for a fix. The dealer advised that there would be a $305 fee to diagnose the problem. They found a faulty belt buckle that failed in normal use. To fix it was going to cost another $805.22 to replace the buckle. I had no choice but to authorize this work. I believe safety related equipment should be covered by the manufacturer, beyond the normal warranty for a minimum of 10 years. Using AI, i find…

We were sitting at a traffic light for a few minutes behind another vehicle. Suddenly, our car accelerated very quickly. My foot was on the brake when the car accelerated. I felt the brake pedal depress further as it accelerated. I initially thought a car had hit us from behind and propelled us forward, but there was no car behind us. We were moving as though we had just started a drag race - full acceleration - and the brakes did not respond. We crashed into the car in front of us at full acceleration despite me pumping the brakes at least twice. It was surreal. We drive a 2019 BMW i3. Itâs an electric vehicle and I wondered if there was som electrical failure. The car stopped only…

The contact owns a 2019 BMW I3. The contact stated that while stopped in traffic on a bridge, the vehicle stalled, and independently shifted to park(P). The contact stated that several unknown warning lights were illuminated. The Police arrived on the scene and directed traffic around the vehicle until a tow truck arrived to take the vehicle to a local dealer to be diagnosed. The contact was informed that the Encrypted Media Extensions (EME) module had failed and short circuited the safety box inside of the high voltage battery and needed to be replaced. The vehicle was not repaired. The contact referenced NHTSA Campaign Number: 19V599000 (HYBRID PROPULSION SYSTEM, ELECTRICAL SYSTEM) as a…

The range extender did not turn on while I was driving the car. When the range extender failed to work the car slowed down from 70+ mph to as low as 7 mph in minutes. The car then limped along for several minutes at this dangerously slow speed until the range extender turned on. Once the range extender began working, the car took off like a rocket, going from 7 mph to 70 in seconds. There are no warning lights or indicators in the car that show if the range extender is going to turn on or if it will fail to turn on. This has happened four times while I was driving on a a highway and once while I was driving on a road with heavy traffic. The first instance happened in [XXX] on my ride back…

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: âDrivetrain Malfunction: Stop carefully and turn off engine. Do not continue driving. Call Roadside Assistance.â 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…

The 12V battery and EME module failed/malfunctioned on Sep 10, 2024. The original 12V battery was replaced by BMW of Wesley Chapel after it was towed by BMW roadside assistance. They should have it and the EME model for inspection upon request depending on their disposal procedures for the battery. My safety was put at risk due to the fact that the EME could shut down electrical power, lead to a loss of propulsion, and increase the risk of a crash. There was a recall for this component for my year make and model but my VIN was not included but possible should have given the related issue and no wear and tear. The dealer reproduced the errors I received when the car started failing during a…
