Soon after, the company released a lookup tool allowing users to confirm if their particular D5000 was affected by the service campaign. Users were recommended to check their serial numbers even if they'd yet to experience any problems with operating their camera.

Today, we've received news that the company is requesting a small number of customers to return their D5000 for a second repair to be made. We also understand that additional serial numbers affected by the issue have been identified and added to the lookup tool - so even if you've already checked your serial number, we recommend doing so again.

Nikon has released a statement which answers concerns raised by the Nikon Rumors website and other online forums about the veracity of the rumored second service campaign, and assures customers that only a small number of cameras are affected by this second advisory, as follows:

"Nikon has developed an enhanced repair procedure that further elevates the D5000's resistance to the power issue identified in a Service Advisory published on July 23, 2009. This additional procedure benefits a small number of D5000 cameras affected by the original Service Advisory. The few customers whose D5000 cameras will gain from this procedure were notified in writing and provided with the materials necessary to ship their camera overnight to Nikon (at Nikon's expense). To minimize customer inconvenience, these cameras will be expedited on a first-priority basis and returned to customers via overnight service (again, at Nikon's expense)."

As per the statement, customers affected by the second campaign have been contacted in writing by Nikon, and are being provided with free overnight shipping in both directions as well as expedited first-priority repair. Kudos to Nikon for doing its best to minimize inconvenience to customers upon ascertaining that further repairs were needed.
