Service bulletin 05-005-15-3027A

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

SOME CUSTOMERS MAY COMPLAIN OF A WHINING NOISE FROM THE AUTOMATIC TRANSAXLE WHEN DRIVING AT 10 MPH AND ABOVE. THE NOISE: • DEPENDS ON THE VEHICLE’S SPEED ONLY (THE MORE SPEED, THE MORE NOISE) • OCCURS WITH ALL TYPES OF DRIVING (ACCELERATION, DECELERATION, STEADY SPEED) • DOES NOT DEPEND ON RPM, GEAR, OR ATF TEMPERATURE. THIS IS CAUSED BY A DAMAGED BEARING IN THE TRANSAXLE DUE TO IMPROPER CONFIGURATION OF THE TRANSAXLE CASE. A MODIFICATION HAS NOW BEEN IMPLEMENTED ON AUTOMATIC TRANSAXLES WITH THE SERIAL NUMBER 3TR1111680 AND HIGHER OR 3TD1104906 AND HIGHER. THE SERIAL NUMBER CAN BE FOUND ON TOP OF THE TRANSAXLE CASE NEAR THE MANUAL SHAFT LEVER.

SSPA1	2017-09-14. Service bulletin. Mazda Motor Corporation has decided to conduct a Special Service Program (SSP) on certain 2014 Mazda6 vehicles produced from November 8, 2012 through September 27, 2013. On certain 2014 Mazda6 vehicles, a concern has been identified with the software of the vehicle control module (VCM), which controls the Smart Brake Support (SBS) and Mazda Radar Cruise Control (MRCC) features. When the vehicle is driven without stopping for a long time, it is possible that a zero-point of the radar sensor may be inappropriately aligned. Under this condition, the warning light will illuminate and the SBS and MRCC features will stop operating. Dealers are to reprogram the VCM with modified software. The repair must be performed at no charge to the vehicle owner.
