What is a Delivery Stop?

A Delivery Stop is a manufacturer-issued hold on vehicles that have not yet been delivered to customers. This action prevents the sale or delivery of new or used vehicles until a specific issue can be inspected and, if necessary, repaired. It's a proactive measure to address potential defects before vehicles reach owners.

Why the Delivery Stop Was Issued

BMW AG initiated this Delivery Stop, effective November 20, 2020, to address a potential concern with the connecting rod bearings in certain engines. The connecting rod bearings are critical components within the engine that support the connecting rods, which link the pistons to the crankshaft. A defect in these bearings could lead to severe engine damage or failure.

This specific Delivery Stop affects a small number of Model Year 2020-2021 BMW vehicles. The affected engines were produced within a specific timeframe, between May 15, 2019, and October 23, 2020.

What This Means for Owners and Buyers

If you have purchased or are awaiting delivery of a 2021 BMW X3 or another affected model produced between May 15, 2019, and October 23, 2020, your vehicle may be subject to this Delivery Stop. Vehicles under a Delivery Stop cannot be sold or delivered until the necessary inspection and any required repairs are completed by the dealership.

For current owners of a 2020 or 2021 BMW X3, M2, or X4, it is advisable to contact your authorized BMW dealer to determine if your vehicle is part of this specific action. While the primary intent of a Delivery Stop is for undelivered vehicles, understanding if your vehicle's engine falls within the affected production dates for the BMW X3 connecting rod bearing issue is important for peace of mind.
