Battery & propulsion recalls (2)
BMW of North America, LLC (BMW) is recalling certain 2018 i3 BEV and i3 REx hybrid electric vehicles. A circuit board problem within the Electric Motor Electronics (EME) module may shutdown the supply of high voltage electrical power.
Consequence: A shut down of high-voltage electrical power would result in a loss of propulsion, increasing the risk of a crash.

Sample complaint excerpts
Electric Propulsion
- [2014] TEMPORARY LOSS OF POWER ASSIST. FROM A STOP, THE ASSIST WILL FUNCTION CORRECTLY UNTIL 30MPH. FROM THEN ON, THERE WILL BE NO POWER ASSIST UNTIL COMING TO A FULL STOP. THE PATTERN REPEATS ITSELF FOR THE REMAINDER OF THE TRIP. ONCE THE VEHICLE IS TURNED OFF, IT COULD TAKE DAYS OR MONTHS FOR THIS TO HAPPEN AGAIN. BMW STATES THEY "CAN NOT REPRODUCE". THIS SITUATION MAKES THE VEHICLE VERY UNSTABLE AND D
- [2014] WHEN THE VEHICLE ENTERS A 'FAULT' MODE, SUCH AS DRIVE MOTOR MALFUNCTION, THE CARS DISCONTINUES POWER TO THE DRIVE MOTOR, ALLOWS THE VEHICLE TO ROLL TO A STOP, THEN ELECTRONICALLY PUTS THE TRANSMISSION IN PARK. AS LONG AS THE FAULT CODE EXISTS THE VEHICLE CANNOT BE PUSHED OR TOWED OUT OF HARMS WAY. I WAS ABOUT TO TURN ON TO A VERY BUSY 3-LANE [NO SHOULDER] HIGHWAY WHEN IT SHUT DOWN. NOT EVEN THE
- [2014] THE BMW I3 ELECTRIC VEHICLE THAT COMES WITH A RANGE EXTENDER HAS A CRITICAL HAZARDOUS DESIGN FLAW. IT CANNOT CONSISTENTLY POWER THE VEHICLE TO MAINTAIN A SAFE SPEED WHEN DRIVING ON A MODERATE INCLINE FOR A REASONABLE PERIOD. IN OTHER WORDS, YOU MAY BE DRIVING ON A CALIFORNIA FREEWAY AND RUN OUT OF ELECTRIC CHARGE AND THE RANGE EXTENDER WILL KICK IN. EVERYTHING IS FINE UNTIL YOU APPROACH A HI
High-Voltage Battery
- [2014] AC Compressor for the car battery system failed. There was a check engine light that was on steady, but not flashing. The electric range in the car reduced by 20 to 30% as a result of this fault. It was brought into the BMW dealership for inspection and they determined that was a short in the AC compressor and that the whole AC compressor system would need to be replaced; compressor, lines and r
- [2014] AFTER A RECENT SOFTWARE UPDATE, THE COMPUTER IS UNABLE TO INDICATE THE ACCURATE STATE OF CHARGE, CAUSING UNEXPECTED POWER LOSS. MY RANGE EXTENDER WAS NOT ABLE TO ENGAGE BEFORE POWER LOSS, AND THE CAR INDICATED 50+ MILES OF RANGE REMAINING. I WAS DRIVING ON A FREEWAY WHEN THE POWER LOSS OCCURRED, WHICH TOOK ME FROM 65 MPH TO A DEAD STOP IN A MANNER OF SECONDS. *TR
- [2016] While driving my 2016 BMW i3 with Range Extender, the vehicle experiences sudden and complete loss of propulsion at very low state of charge (0–1%). The car abruptly loses motive power, forcing me to pull over, sometimes while in traffic. After sitting for several minutes, limited power may return, but the vehicle often shuts down again, and in some cases the Range Extender engine does not engage
12V Auxiliary Battery
- [2014] Car had all warning light came on one day. We brought to a local dealer and they told me it was due to 12V battery was not charging. 1. I asked to a service rep if 12V battery could be issue w/o full diagnostic which they charged me extra. He said they needed to do it to figure out. 2. After replacing the battery, it still had error message. After a few days, I was told car needs software update
- [2017] While driving on the freeway, the vehicle's electric motor suddenly died. Because this is an electric vehicle, the car came to a sudden and abrupt stop, with all the wheels locking up. The car would not shift into drive or neutral or reverse. It effectively died, with the only power coming from the 12-volt battery to power the dashboard and interior lights. It was effectively inoperable. The vehic
- [2018] On May 2, 2022, the car began to power down involuntarily every time I applied the brakes. This happened 2-3 times, and I was able to restart. The final time was in the middle of an intersection, the car would not restart, could not be placed in neutral to be moved out of the intersection, and I had to have a police tow. The tow service took it to Sport Motoring, where they performed a diagnosis o
Charging System
- [2014] TWO ISSUES: 1. DRIVING AT HIGHWAY SPEED OF 65 MPH, WITH BATTERY POWER DRAINED, THE REX (RESERVE ENGINE) TURNS ON. SUDDENLY, SPEED DROPS FROM 65 MPH TO 40 MPH WHILE ON A 2-LANE CA FREEWAY, ALMOST CAUSING ME TO BE REAR-ENDED BY TRAFFIC. ONE MONTH LATER, SAME SITUATION, SAME PROBLEM. 2. MANUFACTURER STATES A COMBINED MILEAGE RANGE OF 80 MILES ON BATTERY, 60 MILES ON REX (RESERVE ENGINE), FOR A C
- [2015] THE CHARGING CABLE WON'T UNLOCK FROM THE CAR BECAUSE OF A BAD ACTUATOR AND SOFTWARE BUG, AND THE FUEL PRESSURE SENSOR FOR THE RANGE EXTENDER FAILED DUE TO CORROSION. BOTH ARE KNOWN PROBLEMS. BMW HAS REDESIGNED THE PARTS, BUT DOES NOT MAKE THE REPAIR BEFORE SELLING THE CARS. IT IS BROKEN FOR THE SECOND TIME IN A MONTH FOR DEFECTS THAT SHOULD HAVE BEEN CORRECTED BEFORE THE VEHICLE WAS DELIVERED. TH
- [2019] 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
Regenerative Braking
- [2015] THE ADAPTIVE CRUISE CONTROL (ACC) IN THE I3 IS SINGLE CAMERA BASED, AND WILL DEACTIVATE DURING A NUMBER OF CONDITIONS (SUCH AS DRIVING INTO DIRECT SUNLIGHT WHICH BLINDS THE CAMERA.) THIS IS A DESIGN LIMITATION, BUT NOT THE PROBLEM. THE PROBLEM IS WHEN ACC DEACTIVATES, THE CAR IMMEDIATELY GOES INTO FULL REGEN BRAKING WITHOUT WARNING. AT HIGHWAY SPEEDS THIS IS A SUDDEN AND SIGNIFICANT DECELERATION T
- [2015] THE CRUISE CONTROL RANDOMLY TURNS ITSELF OFF AND THE CAR IMMEDIATELY GOES INTO REGENERATIVE BRAKING. THE SERVICE TECHNICIAN WAS UNABLE TO DUPLICATE THE PROBLEM AND NO REPAIRS WERE PERFORMED BY THE DEALER. IT HAS HAPPENED UNDER MANY DIFFERENT DRIVING CONDITIONS, AND DIFFERENT TIMES OF THE DAY AND NIGHT ON FREEWAYS AND BACK ROADS.
- [2015] THE ACC (ACTIVE CRUISE CONTROL) SURPRISINGLY STOPS WORKING WHEN FACING A BRIGHT SUN. THIS HAPPENS OFTEN, BUT IT TOOK ME A WHILE TO UNDERSTAND WHAT WAS HAPPENING. IT IS VERY DANGEROUS AT HIGH SPEEDS IF SOMEONE IS BEHIND ME. WHEN THE SUN HITS THE CAMERA, THE ACC SHUTS DOWN (WITH A WARNING ON THE SCREEN) AND THE REGEN BRAKING SYSTEM KICKS IN CAUSING THE CAR TO SLOW DOWN MUCH MORE THAN COASTING. I HA
Hybrid Drivetrain
- [2015] The contact owns a 2015 BMW I3. The contact stated that after turning on the fan, there was plastic particles blowing out of the vents. The contact stated that the check engine warning light was illuminated. The contact stated that the particles were blowing out of the vents while activating the A/C or the heater. The contact stated that the failure became a recurring failure, and the vehicle was
Source: classified from NHTSA complaint and recall data. "Battery-related" includes high-voltage propulsion battery, charging system, hybrid drivetrain, electric propulsion, regenerative braking, 12V auxiliary battery, and thermal-event complaints. Other complaints (suspension, steering, brakes, infotainment) appear in the engine and vehicle-level sections. The rate divides those complaints by the electrified versions built, from the production counts makers report to NHTSA, and it is not adjusted for age. Death and injury figures count complaints that report one, not the number an owner typed in.
