I've had my car for a year and a half bought it in February 2015, I just noticed that the whole trunk has tiny little rust spots all over, and the lower panels. Not sure what this is about, the car is not that old and only went through one mild winter?

Rust spots appearing on lower panels of all four doors. Small rust spots also appearing on trunk hatch.

Vehicle was purchased in May 2015.

Brand new car, less than 10k driven, rust spots appeared all over trunk and rear quarter panels.
