Anyone know the details?

What's your question specifically, for what vehicle year etc.? At any given time there are usually a few active recalls for various vehicles. My Nissan Rogue for example has 3 recalls right now and about 10 TSB's. If you want to check the list of Technical Service Bulletins (TSB) and Recalls, here is the link:
