Snow/Ice build up inside tire rim's, causing improper tire balance. And also brake to freeze up when vehicle is parked, during driving in winter snow conditions. When driving on interstate roads at speed limit, the vehicle start's to shake a lot, like a flat tire. I talked to a Chevy dealer service manager about it and he said that their wasn't any safety massage out on that problem. I've never had a wheel snow/ice up like that before !! So now during the winter I check and clean out the snow/ice out of the wheel rim to prevent the vibration and driving problem. No warning light came on. It just shook the car real badly while driving on the highway.
