Driving on the highway when there was a sudden loud bang, my car swerved, my rpms revved up, white smoke and I smelled burning. I pulled over and had it taken to the local certified Cadillac dealership, my rear differential needs to be replaced related to a rear pinion seal leak. There's a recall for that exact problem for my year and model but my VIN isn't covered. How can I get my VIN on the recall list?.
