What I gather from these forums is that there's a significant number of us that have had and still have the issue, even after having it looked at by a dealership. It's not an issue on the majority of Stingers though. It should be apparent to your dealer if they test drove another Stinger from their lot as a comparison.I had my car in twice over the last month for the sunroof issue. The "fixed" it by installing metal shims as they saw that there was a lot of pressure on the glass. Did it fix it? No. They now claim that it's part of the vehicle's design and works as intended. They said all the other stinger had the rattling issue as well...
