BMW is recalling 27,720 vehicles across three model lines because a worn connection between the driveshaft and rear differential could, in rare cases, let the car roll away on its own, according to BMW’s recall report filed with NHTSA under campaign number 26V525.

Key Points

• The defect involves the connection between the driveshaft and the rear axle differential, which BMW says “may, over time, be subject to excessive wear.”
• Excessive wear can cause a loss of rear-wheel power, increasing crash risk, according to BMW’s filing.
• Without the parking brake engaged, the same wear condition could allow the vehicle to roll away unattended.
• BMW has reported zero accidents or injuries tied to the issue as of the recall filing.
• Dealers were notified on August 12, 2026; owner notification letters go out October 2, 2026, the same day the recall becomes searchable by VIN.

What’s Affected

• 2021-2023 BMW 5 Series: 540i, 540i xDrive, and M550i xDrive (18,150 vehicles, the bulk of the recall)
• 2022-2026 BMW 8 Series: 840i and 840i xDrive (7,372 vehicles)
• 2024-2026 BMW 750e xDrive (2,198 vehicles)

What Owners Should Do

• Dealers will inspect the driveshaft-to-differential connection and, depending on what they find, either apply an adhesive to secure it or replace the entire driveshaft and differential assembly.
• The repair is free of charge for owners of affected vehicles.
• Owners can check whether their specific vehicle is included using NHTSA’s VIN lookup tool at nhtsa.gov/recalls once the campaign becomes searchable in October, or by contacting a BMW dealer directly in the meantime with their VIN.
• Until the repair is done, owners should be diligent about fully engaging the parking brake any time the vehicle is parked, particularly on an incline.

A driveshaft connection isn’t the kind of part most owners think about between oil changes, which is exactly why a slow-wearing failure mode like this one is worth taking seriously rather than shrugging off. BMW’s zero-incidents track record so far is a good sign the company caught this before it became a headline-grabbing problem, but a car that can quietly roll off its own driveway is still a car worth getting into a service bay sooner rather than later.

The 5 Series carries the overwhelming majority of the affected population, which tracks with it being BMW’s highest-volume sedan across the recall’s model years. Owners of the 8 Series and 750e plug-in hybrid make up smaller but still meaningful slices of the count.
