P0141 - O2 Sensor 1/2 Heater Performance. ? P1D73 - Active Grill Shutter (AGS) Performance. ? P113D - O2 Sensor 1/1 Slow Response (2015 only). ? Engine bump sensation felt during moderate to heavy acceleration over 3500 RPM. ? DTC P061A - Level 2 torque performance set. ? Engine difficult to restart after cold or warm soak periods. ? Intermittent high coolant temp warning lamp illumination when using cruise control. Condition occurs in conjunction with the P061A DTC listed above. ? Poor A/C performance primarily during extended hot idle and/or low speed driving conditions. Applies to vehicles built with 1234YF refrigerant sales code XFC. ? Black smoke from tail pipe on initial start up during cold ambient temperatures (2014 only). ? Cold start difficulty below -10C (14F) ambient temperatures. Engine cranks fast and possibly does not start due to loss of crankshaft synchronization until key cycle is performed.
