## NHTSA's summary

Supersedes Technical Service Bulletin Group 91 number 14\-20 dated January 3, 2014. When the driver uses the Bluetooth hands\-free telephone system to make a call, the listener on the other end cannot clearly understand the driver. The driver's voice sounds muffled, as if it is being heard from under water. The microphone seal was damaged during installation into the roof module.
