I tend to replace stuff that breaks with better stuff. Original is not always best. Assuming the Dahon is original, the pedals are 35 years old--- a long span for what is basically a weight supporting hinge. FWIW, I have 2 Schwinn Loops for takealong bikes on trips. I've had to get new pedals for one of them (mine) after the first ride. The one my wife rides is still ok, though they both came with one folding pedal (right side, on the outside when the bike is folded) and one nonfolding. The cheapness can be staggering.
