A few days but my salesman gave me the Nissan contact phone number and I asked for the refund. Nissan said they had to get the dealer info updated, but I guess they took care of it as I saw it processing on the card in a few days.For those who weren't able to get the reservation deposit ($500 USA) deducted from the purchase price at the dealership, and elected to have the amount credited back to a charge card, how much time transpired before seeing the credit show up on the charge card account? Dealer claims "within 3-4 weeks" - which seems overly conservative. But consistent with Nissan's never ending fumbles with the Ariya launch process . . .
