2023 BMW i4 Electrical System Problems

I was driving about 30 mph when I was prompted with the following error message, “Drive train fault, restart not possible, High Voltage Battery,” I was able to drive home which was about 1 mile away. I drove the car home, parked it and turned it off for 45 minutes then I attempted to turn it on but was unable to and continued to receive the same message. Side note, this vehicle was purchased from BMW Beverly Hills on 1/25/26 and not a month went by before I ran into this issue.

Electrical system stalling stopping the car it won’t move breaking system

The only way I could explain it was as if my brakes were failing. After joining the bmw i4 group on Facebook and having my kids record while driving. I was able to capture the issue. The vehicle drive train will malfunction causing the vehicle to move while not in motion when at a stop light. The vehicle will accelerate on its on. It has recently power off on me while driving and restart back up. I took it to the dealership they said it was fine. I took it today. They couldn’t offer me and my kid ride home or a loaner due to policy. I even asked to trade my car in. I was told that I was driving it wrong. I know my car keeps data on when these incidents occur. I have photos.

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.

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION A

The contact owns a 2023 BMW I4. The contact stated while reversing, the drive train malfunction warning light illuminated. The contact proceeded with his commute however, the steering warning light illuminated, and the vehicle shifted into park independently. There were several messages displayed on the infotainment screen, and the contact was unable to shift the vehicle back into drive. The vehicle was towed to the dealer but was not yet diagnosed. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 16,000.

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.

The car is brand new and does not connect to a level 3 charger. BMW service has no idea how to fix.

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.
