Yes, but this is more true of stainless steel and aluminum than regular carbon steel and aluminum. Water must be in contact with both metals to create this "battery" effect so I don't really think it's an issue with a race car. Using aluminum rivets on the aluminum panels would mean trading the risk of corrosion for the risk of vibration failure.
