According to the notification received by MORryde International; Look for the black seal that is visible in the center of the pulley as shown in the pictures below. If the pulley does not have the seal, there is nothing further that needs to be done. If the pulley has the black seal and was manufactured during the date range, the cable and pulleys need to be replaced.
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
