The bad sound bad braking and general disappointment in Chevy for not being able to fix this problem twice at 800 a pop through and 6 month of trouble shooting and again 800 thought the Goodyear guys they are much more considerate to one dollars being spent with them. The dealership was nothing but problems and I don't knows. No long under warranty I haven't found a permanent solution but own the car all out now along with the problem. The cleaning the sensors is the longest fix I've encountered. Help me if you've been able to get rid of this problem. Still luv my Chevy's just a bad call on what should've and could've been a minor, quick, and name saving recall. So any Chevy Reps reading this get off your ass and fix this sh*t!
