ELECTRICAL SYSTEM

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.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM, POWER TRAIN

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.

UNKNOWN OR OTHER

While driving on frewway in HOV lane next to tall concrete center barrier, side collision mitigation system suddenly began to aggressively and continuously jerk steering right and left. After about 10-20 seconds this caused loss of control, with vehicle turning around 180 degrees and, during the spin, impacting the center concrete wall, causing deployment of all airbags. Traffic was very heavy, and although there were no injuries or collisons with other vehicles, the loss of control was life-threatening. This route was driven previously under exactly the same conditions (clear, dry day in HOV lane) with no problem more than 20 times. This problem occurred about two weeks after the latest BMW software update. BMW was informed and what they might do is unknown.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER

On [XXX], while driving on a public highway, the vehicle shut off and came to a complete stop as I was going around a roundabout. I was in the inside lane, had just finished charging in Yuma, Az., and was just about to get back on the freeway heading back into California. Thankfully, there was no one behind me at that moment and I was able to restart the vehicle and continue driving. After arriving at my destination in Winterhaven, CA, I later saw that I had two missed calls from BMW Roadside Assistance. They called to check on my welfare as, unbeknownst to me, the vehicle sent out an alert as a result of the incident. 12/30/2023, I took the vehicle to BMW of San Diego (where I leased the car from) regarding the above mentioned incident as well as repeated Drivetrain Malfunction warnings. The vehicle had 43,770 miles on it. By 1/12/2024, the dealership informed me they could not replicate the problem, and what I found most alarming, was they could find no evidence that it ever happened. I asked if they could promise me it would not happen again, they could not. This caused me great fear for myself and for others. All they could offer was that I could file a claim with BMW of North America, which I did that same day. It was not until 3/19/2024 that BMW notified me they rejected my claim. On [XXX], as I was returning home from El Centro, CA, I received a warning message, "URGENT HIGH VOLTAGE SYSTEM CHECK UP" and directing me to the nearest service center. Again, I took the vehicle to BMW of SD, stopping to charge along the way, because the range was dropping rapidly. The mileage was 95,074, still under warranty. Again, they found nothing and made me take the car back. Ultimately, on [XXX], another alert "Range reduced: Limited charging possible. Have problem checked by the nearest service center." At BMW of El Cajon I was told that Cell Module #2 had failed and would need to be replaced, but now the car was out of warranty and my cost would be $23,366.

SUSPENSION

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
