There was one out awhile ago that had to do with how the battery state was sensed, potentially leading to the car thinking it had less capacity than it actually had...there could be a newer one, but I haven't heard about it. My car goes in next week for the airbag recall. That one was not a recall, but a service campaign. To the end user, there may be a subtle difference, but a recall is a safety issue and monitored by the government...a service campaign is not mandatory, and is voluntary, but recommended to fix a non-safety issue or add an enhancement.
