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

While driving, the vehicle experiences intermittent braking failures, electrical glitches, and/or sudden loss of power. These issues match known problems reported on similar 2023 BMW i4 models. My VIN does not show an active recall, but I am experiencing dangerous symptoms. I am concerned for my safety and others. I respectfully request an investigation.”

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 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.

As I was driving my car into the main avenue out of a parking lot, the car stalled and lost all power, the charge went from 57% to 0% and the power train failure warning came on the dashboard and a high voltage warning as well. The incoming traffic had to stop since I could not move the car, so I had to turn power off and power back and only then the car started to move slowly, the battery charge went up only to 37% and both warnings were displayed on the dashboard (high voltage warning and power train failure) with a message that said that it was OK to drive the car to a dealership to get the car checked.

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.

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. Vehicle was taken to dealership for repair and item know as cover pot defect was confirmed and replaced. Requested confirmation that replacement part addressed root cause but dealership would not offer any assurances.

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

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.

Drivetrain malfunction, made car inoperable. Went into park mode. No neutral ability to move. Had to be special tow. Car is 2 days old. Only 200 miles on odometer. Check internet, many many same issues.

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.
