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.

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.

This is the second time the brakes failed on this vehicle. The first incident, occurring as I pulled into my garage, in May 2023, was investigated by BMW North America and the vehicle was deemed to have no defect and to be safe to drive. The second incident occurred on [XXX]. The car was traveling approximately 15-25 mph on a collector road between [XXX] in downtown Los Angeles. The car immediately in front of me applied its brakes and when I applied my brake pedal the vehicle did not respond and my car did not slow down. I did not see any sort of warning lamp on the dashboard. I hit the car immediately in front of me and that car hit the car in front of it. My airbags deployed. The car called emergency services. No one was injured. My vehicle is now being examined by BMW North America. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am writing to file a formal complaint with the National Highway Traffic Safety Administration (NHTSA) regarding a serious safety issue with my recently purchased 2023 BMW i4. The incident involves a brake malfunction that occurred just two weeks after the purchase, posing a severe risk to my safety and potentially the safety of other road users. On 07/11/, while driving my newly acquired BMW i4, I experienced an alarming brake failure, which almost resulted in a collision with another vehicle. Fearing for my life and the lives of others, I immediately took the car to the authorized BMW service center in Fremont for immediate inspection and repair. Regrettably, it has now been over a week since I dropped off my car at the service center, and it remains unrepaired. The service center personnel informed me that they need to order a brake boost from Germany, but I am deeply troubled to learn that there is still no estimated time of arrival for this critical part. Consequently, I am left without a functional vehicle and potentially exposed to further brake-related hazards. This incident raises serious concerns about the safety and reliability of BMW's brake system in the 2023 i4 model. I find it unacceptable that a reputable automotive manufacturer like BMW does not have the necessary spare parts readily available for essential safety components like brakes. Furthermore, I am disappointed by the lack of transparency and communication from BMW throughout this ordeal. The uncertainty surrounding the repair process has caused significant distress and inconvenience, adding to the already harrowing experience. Given the gravity of the brake malfunction and the prolonged delays in repairs, I believe it is imperative for the NHTSA to investigate this matter thoroughly. The potential risks posed by a brake system failure are a matter of utmost concern and warrant immediate attention and action.

I opened our garage door remotely, as I always do, and pulled into the driveway. As I entered the garage, I attempted to brake but the car continued to roll despite my pressure on the brake pedal. The car ran into the shelving and other items against the garage wall. I have entered our garage in this way many thousands of times, and I am confident I did nothing differently this time.

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)

Sudden acceleration when entering an open parking space, causing the car to hit two vehicles and causing extensive damage to my and the other vehicles. Safety of others would have been at risk as the accelerations was unintended and unexpected and if people were present they would have been in danger. The vehicle is currently at dealership for examination of unintended acceleration and accident. No warning of sudden acceleration nor any issue with car prior to accident. Air bags were not activated. Police contacted but since noninjury no report filed.

The contact owns a 2023 BMW I4. The contact stated while turning into a parking space, the vehicle experienced sudden unintended acceleration and crashed into a post and then into a wall. No warning lights were illuminated. The contact stated that there were no injuries sustained. A police report was not filed. The vehicle had not yet been taken to an independent mechanic or a local dealer to be diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 2,098.

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)

I believe the tire size is 245 R40 19. The tires interior seams on both rear tires are coming apart. Car has just passed 21K miles, and is driven very carefully. No pothole damage either.

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.
