Owners of affected vehicles are being notified, and will need to report to their local dealership. The free repairs will replace the timing chain, chain guides and crank sprocket.
Take a look below for a short statement to Autoblog from Nissan.
UPDATE: After publishing, Nissan communications representatives reached out to clarify that the timing chain issue with the Juke has been classified as a voluntary "service campaign" as opposed to a voluntary "recall." The presumptive difference in label here being that Nissan will issue a service campaign when it believes the defect in question does not pose a safety risk, but is "important enough to ask owners to come in for a remedy."
Nissan is committed to a high level of customer safety, service and satisfaction for JUKE owners and is working with its dealers to promptly address this issue.
