| A171568 2028440- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL; FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY. Supersedes Technical Service Bulletin Group 17 number 14-49 dated April 3, 2014. 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. |
| A971552 2042450- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM. A rattling noise is heard from the right dash panel area when the car is driven with light acceleration (between 15 mph and 25 mph). The bracket for the starter motor wiring harness has a locating tab that can vibrate. |
| A701550 2029280- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Supersedes Technical Service Bulletin Group 70 number 15-45 dated April 15, 2015. The customer may report hearing noises from the upper dashboard area when driving on poor roads, making phone calls, or playing music. The noise can be caused by unfavorable tolerances between the instrument panel speaker and the center speaker trim. A speaker that has been incorrectly installed can make the condition worse. Because there is no attachment to the trim carrier in the speaker cut-out, this area is the likely source of the vibration. |
| A241551 2038212- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 24 number 14-50 dated August 28, 2014. The engine judders or runs erratically.

Possible incorrect function on the sensor elements of the air mass meter. |
| A201556 2041594- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 20 number 15-55 dated November 6, 2015. The MIL is on. DTC P046100 (Fuel level sensor, circuit range/performance) is stored in the engine control module (ECM). |
| A201555 2041594- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 20 number 15-50 dated October 19, 2015. The MIL is on. DTC P046100 (Fuel level sensor, circuit range/performance) is stored in the engine control module (ECM). |
| A011309 2014753- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM; FUEL SYSTEM, GASOLINE. Supersedes Technical Service Bulletin Group 00 number 10-01 dated February 5, 2010. Excessive accumulation of deposits on intake valves, intake manifold, fuel injectors and combustion chambers. Engine runs rough after cold start. Excessive engine cranking time. Hesitations while driving. Rough engine idle. Reduced engine performance. Poor fuel economy. Conditions may be severe enough to illuminate the MIL in conjunction with storage of DTCs for misfire (example: P0300, P030x) and / or lean fuel system (example: P0171, P0174, P1128, P1130, P1136, P1138) in the engine control module (ECM). Condition may be caused by use of contaminated gasoline. Condition may be caused by use of gasoline with a low content of deposit control additives. |
| A011256 2031368- | 2017-11-08. Service bulletin. FUEL SYSTEM, GASOLINE; ELECTRICAL SYSTEM. MIL on. Engine misfire. Poor performance. Unnecessary High Pressure Fuel Pumps replacement due to Guided Fault Finding test plans not being performed or interrupted when the following DTC?s are present in the engine control module. |
| A901238 2032113- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT. The customer may state that the outside ambient temperature display is incorrect. To achieve a smoothening effect of the displayed outside ambient temperature, the value shown does not instantaneously follow the temperature sensor measurement. The display will not change faster than 4° F (2° C) per minute. This concept applies to both falling and rising temperatures. A programming strategy is also implemented to avoid incorrect readings on a parked vehicle, due to the temperature sensor being affected by outside influences such as radiant heat from the engine bay, elevated road surface temperatures, etc. |
| A571402 2022032- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. Supersedes Technical Service Bulletin Group 57 number 13-97 dated October 29, 2013.
