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.

| A911437 2030947- | 2017-11-08. Service bulletin. EQUIPMENT:ELECTRICAL; ELECTRICAL SYSTEM:SOFTWARE. Supersedes Technical Service Bulletin Group 91 number 13-92 dated July 16, 2013. The customer complains that when he or she is trying to place a phone call from the vehicle while using a Bluetooth®-connected phone, the phone call disconnects before it begins and an error shows on the MMI display. The message may be "Function not supported" or "Network error". The customer is using a phone with the Android operating system. In addition, Skype®, or another network-based communication software, is installed on the phone. Call can be placed directly from the phone without a problem. When the phone receives the request to place a call from the vehicle, a prompt appears on the phone asking the user to choose how the call should be placed. If the prompt is ignored, the MMI system disconnects the call because it assumes that the phone is not responding. |
| A171449 2028440- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Supersedes Technical Service Bulletin Group 17 number 12-26 dated January 20, 2012. When the vehicle is completely refueled, the vehicle range (?distance to empty?) that is displayed is different than the vehicle range that was displayed the last time the vehicle was completely refueled. The displayed vehicle range drops inconsistently. After the vehicle is refueled, the displayed vehicle range does not change for a long period of time. When the vehicle is driven on hilly roads for a long period of time, the displayed vehicle range suddenly changes by a significant amount. There are no DTCs related to fuel senders stored in the instrument cluster control module, J285 (address word 17). This condition does not involve or affect the accuracy of the fuel level indicator, but only the estimated distance to empty display on the on-board computer. |
| A961482 2036344- | 2017-11-08. Service bulletin. LATCHES/LOCKS/LINKAGES:DOORS:LATCH; EQUIPMENT:ELECTRICAL:ANTI-THEFT DEVICES. The vehicle's anti-theft alarm sounds when the driver door is unlocked with a mechanical key. No DTCs are stored. The keyless remote was not used to unlock the vehicle. In order to minimize current draw after the ignition has been turned off, the electronics system of the vehicle goes into sleep mode. During this time, each module monitors the CAN bus more slowly than when the electronics system is awake. Because the system is being monitored more slowly, there is a delay in the waking of the central locking system. This delay causes a delay in the disabling of the anti-theft alarm system when the manual key is used. If the key is turned in less than a quarter of a second, the system can unlock the vehicle even though the anti-theft alarm has not been disabled. |
| A911429 2026888- | 2017-11-08. Service bulletin. EQUIPMENT:ELECTRICAL. Supersedes Technical Service Bulletin Group 91 number 12-50 dated August 1, 2012.

After the airbag control module (J234) has been replaced, the control unit cannot be coded via SVM spec/actual. An SVM code is required to code and parameterize the new service replacement airbag control module. Each model's SVM code is provided in a parts bulletin (GP bulletin), which should have been referenced through ETKA when the module was replaced. The control module cannot be coded until the SVM code has been executed. If the SVM code was not acquired through the GP bulletin in ETKA, follow the instructions in the Service section of this bulletin to update the control module. |
