I have a 2016 Stingray with 13,000kms and while cleaning under the hood, noticed a black powder on the passenger side inner fender and various other areas. It was my serpentine belt that had the center groove missing and the steel belts showing. The dealer replaced it, plus examined the pulley to check for a cause. The belt was defective.
This may be something to watch for.
