I have a 2011 Acadia with 65000 miles about 2 weeks ago I put on the brakes and it sounded like the anit lock brakes were trying to kick in and all you hear was a horrible grinding sound then the traction control turns off, then abs turns off and a message of service stabilitrac...once the traction control is off and you stop there is no sound, I have had it in the shop they said code came back as sensor and hub..they have now replaced the sensor & hub but it did not fix the problem..they have traced all wires that go with the abs system and have found no problems, now they want to order another hub the think the other one is bad...the repair shop said they have called around to other service techs even gmc service and was told that other vehicles are having this problem and they are not sure on how to fix it...has anyone else had this issue and if so what was done to fix it..
