You didn't say what model year and mileage (odometer) on your car? Have you been driving every day or has the car sat for long stretches?What is the age and condition of the 12V starter battery? Is it the OEM or been changed? Do you keep it fully charged if not being driven frequently? An old, weak or worn out battery can cause a multitude of issues and throw fault codes and EMLs.Did the car fully charge to 16 bars?Getting a turtle when accelerating hard such as up a hill can happen if one of the cells is weak and out of balance with all the rest, and drops voltage below the cutoff limit. It usually happens more at lower charge levels such as between 2 and 8 bars. You might be able to trigger it to occur again by making some wide open throttle acceleration runs. A weak cell has less capacity than all the rest, and it's voltage will fall quickly under load, and rise back up quickly when charging. At full charge a weak cell will not show up in the cell voltage graph; take a look at them again with the pack down to 8 and 2 bars.
