Good that they changed one I would have thought they'd do both. It's not surprising that the dealer didn't know about the recall info or even take the time to look into it. I've owned 3 Nissans over a 12 year period and dealt with 5 different dealerships 3 of which only cared about their bottomline not the customer.
Before I sold my Murano I took it to my local dealer (where I'd bought 2 other vehicles) to get the door unlocking sequence changed. They wanted to charge me $100+ dollars for a 10 minute job. I vowed at that time to drive the extra 40 miles to the other dealer for anything I needed done to my vehicle.
