Steering

15 reports
“Power steering malfunctioned causing steering to be very stiff. This happened whenever the car exceeded about 25 MPH, and returned to normal at low speeds. The car wanted to veer out of the lane and required force to keep it in the lane. After turning the car off and back on, the car steering returned to normal. This event happens sporadically, about once a month. While the steering can be overpowered to keep the car on course, this can be very dangerous if you are not expecting it.”

Structure

7 reports
“When driving down the interstate the carbon fiber roof suddenly delaminated of its top layer causing the cars behind me to have to slam on the brakes as chunks of carbon fiber flew off the car. This is a known issue with the BMW carbon fiber roofs that is worse on the i3 because of instead of a weave it is forged carbon.”

Air bags

7 reports2 related recalls
“I am the owner of my BMWi3. We live in a retirement community in Florida and it is the perfect vehicle for driving the short commutes of our daily activities. December 27, 2020 I ordered (from Amazon) SUNTUE Buckles Extender,Universal Fit for 7/8'' Metal Tongue, Extension Socket Connector with E11 Safety Certified -2 Pack. The purpose was to make it easier to fasten the seat belts. We are in our 70’s and it is difficult to reach down to fasten the belt. Our fingers are not as nimble as when we were young. I installed them in mid-January 2021 and a few days later the message appeared: “Driver restraint system malfunction. Continue wearing safety belt. Consult nearest service center.” Shortly after the warning appeared, I removed the extenders and thought the warning would go away. However, it continued to appear. After seeing the message for several months, I called BMW for an appointment to clear the message. September 23, 2021, I paid $160.10 for a diagnostic test, and the BMW Service Advisor told me the SRS – Airbag Driver Front: high resistance in driver airbag must be replaced. He assured me the problem is NOT related to the seat belt extenders. The advisor…”

“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 towed to the dealer. The contact had the vehicle towed to a local dealer, where it was diagnosed and determined that the A/C compressor needed to be replaced. The vehicle was repaired. The contact stated that after the repair, the check engine warning light illuminated again. The contact had the vehicle towed back to the same dealer who diagnosed and determined that a component of the A/C system that cooled the electric hybrid battery needed to be replaced. The contact was advised by the dealer that the repair needed to be completed due to the risk of the battery overheating and catching on fire. The vehicle had been repaired; however, the contact was afraid of driving the vehicle. The manufacturer had been informed of the failure and the contact was advised that this…”

Vehicle speed control

“I was driving uphill on a winding, narrow highway, California State Route 18, when the range extender kicked in and I had a sudden loss of power. I could not maintain vehicle speed. It was terrifying. I was alone. I didn't know what to do. I turned on my hazard lights and I pulled over every time vehicles came up behind me.”

Power train

4 reports
“THE CAR SUDDENLY SLOWS TO 5MPH UNDER SOME CONDITIONS. THIS CAN BE EASILY AVOIDED BY RETURNING PROGRAMMING TO INTERNATIONAL. WHILE DRIVING MY CAR HOME IN WINTER IN RAIN I NEED TO HAVE HEAT, WIPER AND DEFROSTER ON. MY HOUSE IS IN HILLS. UNFORTUNATELY ON RETURN TRIP MY BATTERY IN WINTER IS DEPLETED AND THE ONBOARD GAS ENGINE GENERATOR IS UNABLE TO KEEP UP WITH HILL CLIMB AND NEEDED HEATING AND WIPER. THE CAR WILL DROP FROM 55MPH TO 5MPH WITHOUT WARNING. THERE IS NO AUTOMATIC FLASHER OR ANY OTHER ITEM TO WARN OTHER DRIVERS OF MY PROBLEM. PLEASE ASK BMW TO RE-FLASH PROGRAMMING TO ALLOW MY TO MAINTAIN GREATER THAN 5% BATTERY LIKE THE REST OF THE WORLD HAS.”
