Service bulletin A911303 2034842-

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Supersedes Technical Service Bulletin Group 91 number 13-94 dated July 24, 2013. The driver?s voice sounds muffled or background noise sounds very loud to other caller during Bluetooth calls. Voice recognition commands are not recognized or voice recognition accuracy is poor. The location of the microphones within the roof module make them susceptible to interference by the vehicle air vents and climate control settings. When the center air vents are pointed upward, they can cause a ?swirling? effect that affects the audio quality of Bluetooth® and voice recognition. This is particularly evident on hot days when the A/C system is set to ?auto?.
