Well, there are a few possibilities, but first I'd suggest removing the servo horn & then try centering the servo(do that by centering the steering on the transmitter & then power up the car's electronics so the servo should go to its center position), then reinstall the servo horn(noting what position seems right to keep the steering rack centered). If that doesn't work, then it's possible you could have some stripped gears in the servo, but you should try to exhaust all other possibilities first. Oh, & the RC Tech Site Forum is actually just the place to ask about the site itself, for stuff about the cars or electronics, or tracks, there are suitable sections for that(& I'd say yours might be best in the Radio & Electronics Forum), & you should get a better response there, so I'm going to move it to the Radio & Electronics area now....
