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.

B6507172018-11-05. Service bulletin. EQUIPMENT. "LIST OF AVAILABLE FM RADIO STATIONS TEMPORARILY NOT AVAILABLE. INFORMATION As of 11/2015, all Entry-NAV/Media head units supplied in new vehicles were upgraded for improved noise characteristics and quality. As a part of this upgrade, the hardware updating the sender lists was changed from an "update after every diversity reception interruption or maximum of four minutes" configuration to "regular interval updates (every four minutes) without regard to diversity reception status" configuration. This may cause a delay of up to four minutes for updates to the sender list when leaving areas of poor reception. The last received transmitter, before the entrance into underground car parking or a tunnel, is still received and will show station identification. This fixed interval update does not apply to Traffic Message Channel updates which remain active. This new equipment operation pattern may be noticed by the customer after replacement of their Head unit. All replacement Head units delivered since 01/2016 have the upgraded design. An immediate solution would be for the customer to select one of their stored favorite stations via the menu or favorites buttons. PARTS INFORMATION Parts exchange or a software update are not effective or approved for this situation. WARRANTY INFORMATION Not applicable."

B1206172018-11-05. Service bulletin. ENGINE AND ENGINE COOLING. ?THE ENGINE WILL NOT START AND THE DME IS NOT RESPONDING. The engine does not crank or start and various Check control messages may be displayed. When performing diagnosis with ISTA Next the DME is not responding. Fault: S 0392 - No communication with engine electronics is displayed. Many other modules will have CAN faults stored due to missing messages from the DME (transmitter). Fuse 83 (5A) is open. When the turbocharger coolant pump is activated by the DME, the initial starting current could briefly exceed the 5A rating of Fuse 83 causing this fuse to blow. If this occurs the engine will stop and cannot be restarted.
