I'm looking at purchasing my first car, in this case a 2015 Certified Pre-Owned Mazda3. The dealer is giving me a decent base price with a $900 Certification/reconditioning fee on top ("down" from $1495). I get annoyed with these types of fees not being in the base cost, since the vehicle has already been certified, it's not like it can be undone (if you're selling a CPO vehicle, why wouldn't your advertised price include the Certification cost?), but ultimately he's got me at a price point that I'm more or less happy with out-the-door...it's a touch higher than I wanted, but I expect that's kind of how car-buying works. I'm in Chicago with the worst TT&L imaginable so anything I can get off the back end is especially worth it to me.

There is one issue that is driving me crazy though which is that Mazda3's from this period have a known issue where the steering wheel leather wasn't coated well enough in whatever sort of protection it's supposed to have and so it flakes and disintegrates. There is a TSB about this you can look up on NHTSA, and this particular vehicle I'm looking at has a bad case of steering-wheel eczema. I'm trying to get him to agree to get this taken care of as a condition of sale but he's not really budging either.

In your opinion, is it unreasonable to expect that a known issue with a TSB should be fixed on a CPO vehicle? even if the original owner wasn't prescient enough to take care of it during their original warranty period?
