This is likely the area that sees the most air turbulence when the vehicle is moving forward and the wheel is spinning at a high rate of speed.
No offense and I apologize but your comment is laughable. What you believe or speculate is not valid. You're simply creating a hypothesis based on what you've read and focused on from forums.
Forums are places to enjoy and air grievances about service, warranties etc. They're not the end all to be all. There postings represent a very small percentage per capita of owners and complaints. So what you're alluding to is nothing more than; hypothetical supposition and not theory.
Painted alloy cast or forged wheels go thru a different process when painted then the body of a car. You should never utilize any caustic cleaner on them. Never wipe them off dry. Never utilize a wheel brush on them. You should always touch up nicks and dings with the matching paint and clear coat required. It can be purchased a the dealership part dept. or thru online Hyundai OEM parts vendors.
The wheels on the R-Spec and the VN are completely different. The R-Specs are painted entirely in one specific color and that's black. You're wheels are a cast alloy. On the VN they are forged. If you nick the paint you expose the unprotected cast alloy to the elements, they'll immediately start to corrode from just the moist air. If you have any corrosive material being utilize on the roads you travel in the winter, it will most certainly cause alloy rust and permeate to more than just the nick. This is just how alloy corrosion works.
If you've not taken the time to sealed your wheels with a ceramic coating, then touch up any nicks that have developed, you'll have corrosion forming. Cast alloy wheels are porous. Your wheels are specifically cast alloy.
This will explain much better. It's technical but well worth the read;
I would be very grateful they've replace the wheels up until now. They really didn't have to. I would also seriously think about what I've commented to and provide you as factual information, not the speculation which your engaged in presently. It's dangerous, dubious and is simply at best irrelevant. It causes forum members undue stress and concern. Very similar to the old story, "the boy who cried wolf."
The primary reason you haven't received any response from whatever consumer affairs you complained to is; they have no idea and have to rely upon the dealership, manufacture, and the contracted wheel manufacturer for a response.
Hyundai hasn't responded to you personally because they've gone out of their way to accommodate you up to this point. Hyundai offers and offered you a 100K Platinum Warranty which covers everything bumper to bumper except the bumpers when you purchased the Veloster. They also offer a wheel and tire warranty package, which is still available to you for purchase. Talk to your Hyundai Finance Department. Obviously you saw fit for whatever reason to decline them. With these warranties intact, they'll replace the tire and wheels without question.
Personally, I believe you've been treated far better than most Hyundai owners, that opted out of the additional warranty packages. You need to remember and keep in mind, wheels like brakes, clutch linings, etc., are wear and tear items. They're not warranted unless you pay extra to warranty them, as in their Platinum Warranty. You need to read and make yourself aware of what the Hyundai warranty actually includes. If you still have doubts, call Hyundai Assurance and ask. Hyundai Assurance will be more than happy to tell you.
