sounds like the rotors are warped causing shimmy but scan abs and traction codes and post so we can adv
i just took it to firestone and they said it was fine.
but ill get the codes for it anyways
that was your first mistake, take it to a good mech and have codes scanned. if you feel this shimmy and the lights are on there is a problem. AGREED
Check your wheel bearings. When the bearing gets hot it triggers the sensors in the hub. At least mine did.
