AIR BAGS13/03/2015

BMW of North America, LLC (BMW) is recalling certain model year 2015 428i Convertible, 428i xDrive Convertible, 435i Convertible, and 435i xDrive Convertible vehicles manufactured October 22, 2014, to February 27, 2015. Due to a programming error, the driver's front air bag deployment timing may be incorrect. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 208, "Occupant Crash Protection."

Risk: If the driver's front air bag deployment timing is incorrect, there is an increased risk of personal injury in the event of a vehicle crash.

Fix: BMW will notify owners, and dealers will reprogram the air bag control module with corrected software version, free of charge. The recall began May 11, 2015. 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.

These are the terms for a new Bmw. If you're buying a used 2015 428I, remaining coverage is usually pro-rated from the vehicle's original in-service date. Not all coverage transfers between owners — check with a Bmw dealer for VIN-specific remaining warranty.
