While turning my 2022 BMW 540i onto a busy, 50 MPH road, the vehicle suffered a catastrophic drivetrain failure, without any physical trauma such as encountering a curb or pothole. The car experienced a total and immediate loss of motive power (propulsion), leaving me coasting in live traffic. This created an extreme safety hazard as I was unable to accelerate or maintain speed to clear the roadway safely. The failure occurred immediately after a significant temperature stress: taken from a heated garage, driven with no issue for 40 minutes, then parked in 15 degree weather for two hours, then complete failure within moments of starting up after the two hour cold parking block. My reading since the incident reveals that BMW quietly switched a critical drivetrain part from a composite/plastic material to metal in later 2022 production runs, due to temperature tress failures precisely as I experienced. This 'silent fix' suggests a known design defect in early 2022 models that poses a recurring risk of sudden propulsion loss. BMW did not do a recall for this, but they should have: I and other drivers were in real danger when my car spontaneously lost all motive ability in high speed traffic.

On Feb.3, 2023, my wife made a turn into a parking lot. She was driving our 2022 BMW 540. She paused and the engine began to rev up. It then shot forward nearly 50 feet and hurled her over a meridian into another car. She pressed as hard as she could on the brake and suffered a torn meniscus ligament. There were no warning lights and although the car hit front right, no airbags were executed. BMW has not sent an official detailed report from their engineer. BMW advertises brake override so pressing both the brake and accelerator would NOT result in this event.
BMW of North America, LLC (BMW) is recalling certain 2022-2026 840i, 840i xDrive, 2021-2023 540i, 540i xDrive, M550i xDrive, and 2024-2026 750e xDrive vehicles. The connection between the driveshaft and the rear differential may become damaged, possibly resulting in a loss of power to the rear wheels or a vehicle rollaway.
Consequence & remedy
Consequence: An unexpected loss of drive power can increase the risk of a crash. In addition, a damaged driveshaft can result in a vehicle rollaway if the parking brake is not applied, increasing the risk of a crash or injury.
Remedy: Dealers will inspect the connection between the driveshaft and rear axle differential, and apply adhesive or replace the driveshaft and rear axle differential, as necessary, free of charge. Owner notification letters are expected to be mailed October 2, 2026. Owners may contact BMW customer service at 1-800-525-7417. Vehicle Identification Numbers (VINs) involved in this recall will become searchable on NHTSA.gov beginning October 2, 2026.
