I asked for an external car wash. At the conclusion of the wash, i found my seat pushed back. Not to worry, with 3 seat positions stored in memory, this should not be a problem. Pushing the memory button resulted in no seat movement or correation. Instead, the attendant had taken the liberty to reprogram all 3 memory seat positions. Fortunately, my memory is better than that programmed in the car, and my memory certainly cannot be reprogrammed.Bottom line: Simple task: clean the car. More complex task, reprogram stored memory seat positions. Stick to the simple task.
