Answer
Hi Jay.... did you put a scan tool on and see what codes there are...how do brakes feel...check the codes correct what codes come up and then clear them...see if codes come back...if nothing feels wrong in the brakes it could be an intermittent problem...if thats the case i would find a good garage and have them diagnose what the problem might be...hope this helps
