Visual inspection of the driver revealed stress fractures on the display cover and fan cover and the secondary motor out of the bottom dead center (bdc) position.The driver's alarm history was reviewed and revealed four new alarms, 2d fault code.Since signs of secondary motor engagement were observed during the incoming visual inspection, it is likely that these are the customer-reported alarms as the 2d fault code is produced because of the engagement of the secondary motor.One alarm is recorded each time the driver is power cycled after the secondary motor is out of bdc position.The driver in "as received" condition passed all sections of incoming functional testing.Additionally, since the secondary motor of the driver was observed to be out of bdc position, a functional test was performed on the secondary system.The driver functioned as expected while operating on the secondary motor system and sounded a fault alarm as designed.The root cause of the secondary motor engaging (which caused the customer-reported alarms) could not be determined, but may have been caused by impact shock as a result of rough handling as evidenced by the observe damage or a near drop (jolt).The driver performed as intended with no evidence of a device malfunction.This issue will continue to be monitored and trended as part of the customer experience process.Syncardia has completed its evaluation of this complaint and is closing this file.(b)(4) follow-up report 1.
