I have a ez-starter on my nitro rustler trx2.5r and on it , it has 4 prong type thing ( :: ) looks like that and one of the prongs got pushed back into the ez-starter stick that holds the battery.

Does this mean that the ez-starter is broken or is it fixable?

My car is only a few days old, Should I call traxxas about it?

nah, most likely that the pin just popper out of its place when you put the connector in, just take the connect off an push the pin back in, it should pop in, if it doesnt then you may have broken the little clip that holds it, which you can buy the wiring for it for 15 bucks from tower, or less not sure about the price

Im not sure if it is that though because when I put it in the glow plug light doesnt light. I dont know if the glow plug went or if the ez-starter is broken, because Im on my final break in tank after I fix this problem.

ok then, then that wire that has broken off as you say is the glow plug wire, just push it bak up to where it's suppose to be, it should click
