What the reports in each category say, in the owners' own words
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
The dashboard turn signal indicators are blocked by the steering wheel unless I adjust the steering wheel to a very high position that makes driving unsafe. When the turn signals are on, there is no clicking noise like many cars have. I suggest that BMW update the vehicle software to allow the driver to adjust the location of the turn signal indicators within the digital dash display, or also include turn signal indicators in the heads-up display.
While driving my 2023 BMW i4, the vehicle suddenly displayed multiple drivetrain and chassis malfunction warnings shortly after charging the vehicle at a ChargePoint station. The vehicle experienced a sudden loss of power/propulsion while driving, creating a serious safety concern. After stopping, the vehicle began rolling backward unexpectedly and several systems appeared to malfunction. The center display/screens became partially or fully unresponsive/blank and multiple warning messages appeared simultaneously. Due to the loss of propulsion and safety concerns, CHP assistance was required to safely move the vehicle off the roadway. The vehicle was later towed to BMW service for inspection and diagnosis. I am concerned this may involve a failure related to the electrical system, high-voltage battery system, propulsion system, drivetrain, or vehicle software. The sudden loss of power while operating the vehicle created a dangerous driving condition. The vehicle had approximately 76,000 miles at the time of the incident.
Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.

On [XXX] in Columbia SC, my vehicle reported a drivetrain failure at approximately 1800 and advised me to pullover immediately and contact roadside assistance. I promptly parked in the safest space I could approximately within 50 yards of receiving the alert. The vehicle would no longer move once parked to include neutral. BMW roadside assistance took 48 hours to pick up and transport the vehicle to my dealer in Florence SC. I was informed of a recall on the vehicle by the dealership and advised they would not be able to diagnose and repair until they obtained a part from another dealer that allowed them to put it into neutral. Very few updates were provided by the dealership. On 23 December I was informed the vehicle was repaired and ready. I was informed the problem was with the 12 volt battery. The battery was not replaced as it was deemed to be functioning properly after the computer system was updated. I picked up the vehicle on [XXX] with my daughter to drive it 2 miles to our home. 1.5 mile after leaving the dealership the warning came on again causing my daughter to not be able to move the vehicle out of the road at an intersection. The car could not be put into neutral to move it. BMW roadside assistance informed it would be 48 hours before the vehicle could be towed despite me telling them that it was in the flow of traffic. They advised me to locate a tow truck and I would be reimbursed. I contacted USAA roadside and they were able to have a tow truck to the vehicle 3 hours after the failure. I consider this failure to be very dangerous as the vehicle cannot be placed into neutral to move it out of the flow of traffic.

While merging onto an interstate at speed, the vehicle experienced a sudden loss of motive power and came to a complete stop in an active traffic lane. Approximately six weeks earlier, abnormal drivetrain behavior (hesitation and torque interruption) was reported to the dealer. The dealer attributed the issue to tires and recommended tire replacement. No drivetrain diagnostics were performed. Immediately following the incident, a drivetrain malfunction warning occurred. BMW remotely restricted vehicle operation to allow limited driving back to my residence. The vehicle was later towed to the dealer. BMW subsequently confirmed catastrophic electric motor failure requiring full motor replacement. The incident created an immediate risk of collision with surrounding traffic and represents a serious safety defect involving unexpected deceleration and loss of propulsion.

The vehicle randomly caught fire after sitting idle for approximately 8 hours. Going to a conference in Aria Las Vegas and drove over 260 Miles. There was no issues, no indicator warning lights or strange noises during the drive. Arrived at Aira approximately 4:00PM. Parked vehicle on the third floor of the Aira Self-Parking and did not touch the car after parking the car. I received a call at approximately 12:00AM that night from Aria Security. From Aria Security, stated that vehicle has caught fire. Fire was put out by Clark County Fire department, fire report received. A whiteness who called Aria Security, stated he heard loud popping, like small explosions, from driver side front tire before the fire started. Clark County Fire Department stated fire originated on driver side front of engine area. Battery not involved. Car is total loss. BMW NA performed a visual exam only. BMW NA stated that due to damage and connectors being present, could not find cause of fire and unwilling to perform a more detailed inspection. Cause of Fire and involved components are unknown at this time.
The contact owns a 2023 BMW i4. The contact stated that while driving at 20-30 MPH with a fully charged battery, the engine seized on two separate occasions. There was an abnormal grinding sound detected. The inoperable do not drive message was displayed after the failure. The vehicle was towed to the local dealer, where it was diagnosed with drive unit failure. The drive unit, rear axle, and battery were replaced, but the failure recurred. While his son was driving at approximately 30 MPH, the engine seized. There were no warning lights illuminated. The vehicle was towed two weeks later to the local dealer again, where it was diagnosed that the drive unit and drive axle needed to be replaced. The vehicle was not repaired. The manufacturer was contacted, who opened a case; the contact requested a buyback, but no additional assistance was provided. The failure mileage was approximately 16,000.

My 2023 electric BMW i4 was driving normally on the evening of 11/29/2023. I was near the end of a 30 minute commute when a drivetrain error popped on the screen followed by an error that said "increased steering effort." Within seconds of those messages, without any physical signs of an issue, the car completely lost all power and steering and abruptly stopped in the middle of the street. As the car abruptly broke down, it went into park. It was so abrupt that there wasn't even time to pull over or coast to a safer area. I was stopped in the middle of the street. I couldn't restart the car nor could I shift the car into neutral. The car required a tow to the dealership. This is a SERIOUS safety issue. Had I been on a busier street or highway and suddenly lost all power and steering, I could have gravely injured myself and others. The vehicle has since been inspected by the local service center. They said there is a manufacturing defect with the copper brushes in the electric engine. They said the fix is to disassemble the motor to perform a labor-intensive cleaning. However, what is to prevent this issue from happening again? Especially since no parts are being replaced according to BMW. A car breaking down is one thing. A car abruptly stopping and losing all power and steering is an unacceptable failure. I am scared to drive this car ever again.

Suspension
Reports naming suspension components — springs, struts, shocks, control arms and related hardware.
From owner reports, verbatim
I am reporting a recurring, catastrophic suspension defect in my 2023 BMW i4 eDrive40 that results in life-threatening rear tire failure. Despite adhering to all maintenance schedules, the vehicle's rear axle geometry fails to maintain stability, leading to extreme, accelerated inner-tread wear while the center and outer tread remains healthy. Timeline of Events: Initial Incident 5/4/2025 (21,493 miles): Suffered a sudden rear tire blowout while driving due to the inner tire wall wearing down to the metal cords. The dealer (BMW of Fort Lauderdale) performed an alignment and replaced the tires on my expense. Recurring Failure 3/6/2026 (35,200 miles): Less than 14,000 miles after the dealer-certified alignment, the new rear tires have reached a catastrophic state. The inner shoulders are completely bald (2.7mm inner vs 4.8mm outer), exposing the safety protector and creating an imminent risk of a second high-speed blowout. Manufacturer Response: The authorized dealer inspected the vehicle on 3/9/26 and stated the "alignment is within factory specifications," yet they refused to address why a vehicle "in spec" is destroying safety-critical components in under 14k miles. This indicates either a fundamental design flaw in the suspension components (e.g., bushings or control arms unable to support EV weight/torque) or defective factory alignment parameters provided by BMW for this specific model. Safety Hazard & Lack of Warning: This defect is a "silent killer." The failure occurs on the innermost edge of the tire, which is physically obscured by the vehicle’s body and cannot be seen during a standard walk-around. Because this EV has no regular service intervals (like oil changes), there is no professional opportunity to inspect the inner tires. A driver has no way to predict or diagnose this before a sudden, high-speed blowout occurs. BMW claims the car is "within spec," which indicates a fundamental design flaw that makes the vehicle un-roadworthy and dangerous
I was driving down a residential street with cars parked on both sides. My car stopped very suddenly because the passenger side front tire was pierced and flattened by something on the road. Almost simultaneously the car began to oscillate or jolt from side to side and hit a car parked on my driver’s side very hard and then oscillated back to a parallel position. This is a known problem on the i4 edrive community website. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This is a fully electric vehicle and upon arriving at a charger, the charging port door on the car would not open. It is a manual door - normally just push on the outside of the door and it pops opens. In this instance, pushing on the door did nothing, the door was stuck and would not open, putting my safety at risk as I could not charge the vehicle and had only limited range left to drive. No lights or warning messages appeared in the car. I contacted BMW roadside assistance who had me try multiple things, none of which worked. I was then advised there was no way to open the charging door without bringing it to the dealer. This left me, a single female on a road trip with my child 4 hours from home, stuck in a parking lot as darkness was approaching unable to charge my perfectly functioning vehicle. A quick google search revealed this is a known issue to BMW and many have been replaced under warranty, although no recall has been issued. We are expected to just drive with faulty charge door mechanisms until they fail, and just hope and pray you're in a safe place when it happens or have enough charge to get to a BMW dealer. The vehicle has not yet been repaired, waiting on a service appointment.

Driving at night on [XXX] car in front of me swerved leaving a big deer in front of me on a car on my left, the BMW did not warn me, adjust speed, cinch restraints, or brake, There was no collision warning or advanced readiness at all! I hit the deer at 75 approx, went airborne and totaled my car. BMW wanted to see the vehicle and take data from it since even the cameras didn’t record, no safety features on this advanced vehicle functioned at 12,086 miles, this was an I4 M50 loaded, totaled the car INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
