In 2016, when the battery warranty was about to expire (for my 2011 Leaf SL (original owner)), I asked the dealer if they could do anything about it, but they said we were one bar too high (I think we had 9 bars at the time). Within the next year, it fell below that level, but it was too late...
In early May, DB said 'Week of May 28'. On May 28, DB changed to 'Week of June 6' and got the 'Expected Delivery' email. The dealer told me his system said June 10. Got the call today (June 3) and it is in.
