well doing research i found that its part of the wheel hub assembly, we had both fronts replaced under warranty last year about 9,000 miles ago, called the shop they will cover it if it is the wheel hub, so oh well here we go again :gun:

its prolly ur hub, my lights were on for about 2 monthes, then my dad borrowed a nice scanner and found out the pass front wheel sensor was bad. it set me back about 110 bucks
