What 44 owners told NHTSA about the 2023 BMW I4 Gran Coupe Bev

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.

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.

Vehicle is an EV (platform G26) and charger flap door was locked and would not open. Problem is similar to problem reported on NHTSA for BMW vehicles for "fuel filler door will not open", SIB 51 27 20. Safety issue is vehicle can not be charged and creates risk for driver and passengers being stranded. Older BMW vehicles had an emergency release but new models eliminated this feature.

On 6/8/23 I tried to start my car and received the following error: "Drivetrain malfunction: Driving not possible. Call Roadside Assistance" and the car turned off. I tried 3 more times to start the car and received the same message. I could not drive my car, and had it immediately towed to the dealer. This is a brand new 2023 BMW i4 eDrive40 with only 1469 miles on it. Yes, the problem has been confirmed by the dealer, testing confirmed faults for the high voltage battery and a 30F current violation and sporadic software issue. As of 6/23/23, my car is still sitting at the dealer waiting for a fix (estimated for August). There is a recall for some 2023 i4 eDrive40s (campaign # 22V944000) regarding the high voltage battery electronic control unit (ECU) that may cause an interruption of electrical power, and risk of crash increases. I believe my vehicle should be included in this.

On 5/10/23 I was driving approximately 50 mph on a highway when my car slowed to 15 mph. I stepped on the accelerator and nothing happened. On the dash screen there was a warning which stated "drivetrain malfunction. Driving not possible. Call Roadside assistance". So I was stuck with a sudden deceleration on a busy highway and had to creep over 2 lanes to the shoulder and put the car in park. It would not restart. Myself and my child were in the vehicle. It is a miracle that we were not rear-ended. After calling roadside assistance, the car did turn back on and was driven to the dealer. The car spent 2.5 weeks at the dealer and they say a software update resolved the issue. This car was 4 weeks old when the incident occurred. It had approximately 300 miles on the vehicle.

A small spill of liquid (unsweetened iced tea) on the gear shift area inches from the cup holder shorted out the entire transmission of the vehicle, rendering it immovable. This happened while pulling into our garage, but if it had happened while the car was moving on the road it could have caused a catastrophic accident.

On December 9, 2022, I tried to start my car in my garage. The car would not start..The dash read stop auto train failure contact roadside assistance. After calling my car salesman who told me I had to contact roadside assistance myself, I did so. Roadside assistance informed me they were unable to diagnose/correct the problem, and called a tow truck. The car was towed to dealership that day and has been on the lot ever since. After many consultations with the BMW people in Germany, the analysis was that the cell monitoring circuit module needed to be replaced and the replacement part is scheduled to arrive Mid-March, 2023.
