LANE DEPARTURE: LANE KEEP: STEERING ASSIST06/06/2018

BMW of North America, LLC (BMW) is recalling certain 2018-2019 BMW X3 xDrive30i, X3 sDrive30i, and X3 M40i vehicles equipped with the "Active Lane Keeping Assistant" option. The steering wheel may be incompatible with the lane keeping assistant function and may not detect if the driver's hands are off the wheel.

Risk: If the sensors do not properly detect the driver's hands are off the wheel, the driver may not be alerted by one or more warning signals, increasing the risk of a crash.

Fix: BMW will notify owners, and dealers will inspect the steering wheel, replacing it if necessary, free of charge. The recall began on July 19, 2018. Owners may contact BMW customer service at 1-800-525-7417.

Condition-Based Service (CBS) tells you exactly when service is due. Transmission fluid was labeled 'lifetime' but many owners service at 60K-100K.

"Severe service" conditions (heavy towing, extreme temps, city stop-and-go) typically halve these intervals. Always consult your vehicle's owner's manual for the authoritative schedule.
