You know what's funny is I went there for an oil change and mentioned that I needed to go to the parts department and get some windshield wipers. The service writer looked at my mileage and said, we can cover that under warranty.
I've never heard of a dealership replacing wiperblades as part of the warranty. Chevy told my dad his wipers on his 04 trailblazer were normal wear and tear items and he'd have to replace them himself. Nothing but good experience with Steven Jory so far.
