NHTSA Complaint #11090516 — 2018 BMW 540I

ACCORDING TO BMW LITERATURE, UNDER APPROPRIATE CONDITIONS, THE DRIVER IS TO BE ALERTED BY MEANS OF VIBRATIONS IN THE STEERING WHEEL OF EITHER UNINTENTIONAL LANE CHANGES OR VEHICLES IN THE DRIVER'S BLIND SPOT WHILE SIGNALING A TURN. IN MY 540I, I CAN DETECT NO STEERING WHEEL VIBRATIONS AT ALL WITH THE 'LIGHT' AND 'MEDIUM' VIBRATION SETTINGS. WITH THE 'STRONG' SETTING, I CAN SOMETIMES DETECT A VERY SLIGHT VIBRATION ' IF I PAY CLOSE ATTENTION ' BUT IT IS VERY HARD TO DISTINGUISH FROM ROAD SURFACE FEEDBACK. IN ANY EVENT, THE "INTELLIGENT SAFETY SYSTEM" IS NOT ALERTING THE DRIVER OF POTENTIALLY HAZARDOUS CONDITIONS AS IT IS SUPPOSED TO DO. THIS RESULTS IN UNSAFE DRIVING CONDITIONS. MY DEALER AND BMW HAVE BEEN UNABLE TO RESOLVE THIS ISSUE.
