I bought the bike and registered it with Dahon last year in August, well before the recall of May, 2009. The only reason I knew anything about the recall at all was because I saw the notice in a bike shop. This recall did finally suggest to me just why the hinge felt a bit wobbly. I called Dahon, which affirmed that I had a defective part after I read off the serial number.
After a couple followups by my bike shop, Dahon eventually sent the part to them and it was fixed. How many riders are still out there with a defective part, just because Dahon doesn't care to notify its customers directly?
As I wrote earlier, I will never buy another Dahon AND I will discourage anyone I even sort of like from going out and buying one.
