SHORTLY AFTER GETTING GAS, THE CAR WILL REV TO 2-3RPM WHEN LIGHTLY ACCELERATING, AND SEEM TO "RUN ROUGH". THEN, AFTER COMING TO A STOP AT A TRAFFIC LIGHT, THE CAR WILL AUTO STOP AND THEN SHIFT INTO NEUTRAL. I CAN NOT SHIFT BACK INTO DRIVE WITHOUT PUSHING THE START/STOP BUTTON TO RESTART THE CAR. IT DOES NOT HAPPEN EVERY TIME I GET GAS, BUT ALL 3 TIMES IT HAS HAPPENED HAVE BEEN AFTER GETTING GAS.

The car has an auto-stop feature however at times, when the car is stopped, the entire electrical and engine shuts down even while the car is in drive. The driver must restart the car and put the car into park and then back into drive. When the car restarts, several lights/messages turn on including "Service Transmission" and the "Service Parking Brake" message and parking break light. This is a safety and hazard issue as it has happened while in traffic on the freeway when at a standstill.

The car shuts off at random when coming out of autostop, the car will disable power steering when coming out of autostop to make turns making it difficult to turn the steering wheel. Coming out of autostop is typically when you are trying to go or make a turn. This has been an ongoing issue that happens often. The issues began around 60k miles.
