The leaked data included information on about 21,000 customers who bought vehicles or brought them in for service at the former Fukuoka Nissan (now Nissan Fukuoka Sales). It covers addresses, names, some phone numbers and email addresses, and customer information used for sales activities, without card data. No secondary use of the data has been confirmed. [1]

Nissan Motor says Red Hat's server held no other customer data than what leaked, so there is no further risk of leakage. [1]
