BMW of North America, LLC (BMW) is recalling certain 2022-2023 iX xDrive50, iX M60, i4 eDrive40, i4 M50, and 2023 i760 xDrive hybrid electric vehicles. The high voltage battery combined charging unit (CCU) may not have been manufactured correctly, resulting in improperly connected and/or assembled components inside the CCU.
Consequence: An improperly connected or assembled CCU can interrupt electrical power while driving and result in an engine stall, increasing the risk of a crash.
BMW of North America, LLC (BMW) is recalling certain 2022-2025 i4, 2022-2024 IX, 2023-2024 I7, and 2024 I5 vehicles. The electric drive motor software may shut down the high-voltage system, causing a loss of drive power.
Consequence: A loss of drive power increases the risk of a crash.
BMW of North America, LLC (BMW) is recalling certain 2022-2025 IX, 2023-2024 I7, and 2022-2023 i4 vehicles. The high-voltage battery cell modules may not have been assembled properly, resulting in stress on the module frame and possible module failure.
Consequence: Battery module failure may lead to a shutdown of the high-voltage system which can result in a loss of drive power, increasing the risk of a crash. In addition, module failure increases the risk of a fire.
Sample complaint excerpts
High-Voltage Battery
- [2023] 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 fro
- [2023] This is an electric vehicle. The affected part is called a heat changeover value - this value controls the coolant that is used by the car to keep the drive battery cool. The valves have a problem with leaks and when they leak, the car should not be driven out of safety concern. The main battery could overheat causing a fire/explosion. My vehicle experienced this issue and was undrivable for a
- [2023] 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
Electric Propulsion
- [2023] 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. Im
- [2023] I am reporting a recurring safety issue with my 2023 BMW i4 (VIN: [XXX] ), currently at 28,426 miles. The vehicle has experienced three separate incidents of unexpected and complete loss of power while driving. The first incident occurred in March 2025. The vehicle suddenly lost all propulsion without warning and came to an immediate hard stop. I was later informed this was related to a wheel-pos
- [2023] 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.”
Charging System
- [2022] The door to access the charging port stopped opening leaving me stranded unable to get home or to a dealer for repair. If this happened on a highway I would be terrified
- [2023] This is a fully electric vehicle and upon arriving at a charger, the charging port door on the car would not open. It is a manual door - normally just push on the outside of the door and it pops opens. In this instance, pushing on the door did nothing, the door was stuck and would not open, putting my safety at risk as I could not charge the vehicle and had only limited range left to drive. No lig
Regenerative Braking
- [2025] While parking the car it accelerated up over the curb and into the bushes in an office parking lot. The sudden unintended acceleration occurred in B mode with the automatic cruise control system setting to follow the posted speed limit when activated. The cruise control was not activated by the driver at the time of incident. The car went from 0mph to full acceleration while the parking distance
- [2023] Slowed to a stop with B mode engaged. Suddenly car lurched forward prompting me to slam on the brakes. No one was injured or vehicles damaged but it was unsettling. No warning or other issues prior to failure. No manufacture has looked at it and since it’s likely unable to reproduce often a test drive would likely not see it either.
12V Auxiliary Battery
- [2023] On [XXX] in Columbia SC, my vehicle reported a drivetrain failure at approximately 1800 and advised me to pullover immediately and contact roadside assistance. I promptly parked in the safest space I could approximately within 50 yards of receiving the alert. The vehicle would no longer move once parked to include neutral. BMW roadside assistance took 48 hours to pick up and transport the vehicle
Thermal Events
- [2023] 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 a
Source: classified from NHTSA complaint and recall data. "Battery-related" includes high-voltage propulsion battery, charging system, hybrid drivetrain, electric propulsion, regenerative braking, 12V auxiliary battery, and thermal-event complaints. Other complaints (suspension, steering, brakes, infotainment) appear in the engine and vehicle-level sections. Rates are absolute counts, not normalized per-VIN — high-volume models naturally produce more raw complaints than low-volume ones. Self-reported death and injury counts are capped per complaint to limit form abuse.
