Have a new CX-3 and all warning lights on dash keep going on
when I turn car off and restart it is fine for a while than they come back on
They said they replaced the wire harness not sure what that means still do not want car. Do not trust that it will not have problems down the line. Not sure what to doIf you have and OBD scanner then it would be easier to figure it out but if not then just take it back to the dealership and let them do the work.
