Sounds like Lexus is being VERY generous !!
I agree with Rnpjstwart. I've driven my Porsche (traded in for the ISF) very hard and never had the brake dust issue. I also agree with the other posters that "we" the owners are responsible for the upkeep and maintenance of our auto, tires, and rims. But...
I still don't agree that this is acceptable, especially when I do make sure to get my car washed once per week (hand washed). I've been going to the same hand car wash place with my last three cars so I know that the cleaners that they use are not causing a chemical reaction with the rims.
Perhaps there are differences in production tolerances and "we" both got "Monday" production rims while some of the posters have been lucky and not experienced the pitting. This isn't a complaint as much as an FYI for other ISF owners to make sure that what happened to at least two of us will be avoided (if possible). At least the original poster's dealer is replacing his rims where as I will have them repainted (not my first choice).
One of the posters mentioned that bringing issues like this to the attention of Lexus could cost others by raising the price and is "shameful." What is shameful is blaming the owner for raising the issue and not being open to a discussion about an issue that can possibly affect that poster as well.
We are not going after the auto manufacturer. We are raising awareness about a possible problem that the brake pads or a component of the rims. And at $2,200 per rim I'd say that this could be an expensive issue that you'd want to know about right? Some of us worked very hard to afford this car while others can easily switch cars at this price level at a whim. But an issue with $8,800 worth of OEM components should be of some interest. Money is money after all.
So, once my rims are re-painted and the original poster's rims are replaced, what products (brand names please) would you recommend to prevent this from happening in the future (if this is possible) and how often do you clean your rims to keep them from pitting?
What is your rim cleaning technique, frequency, and product of choice?
That's why this forum exists. To share information and to learn about how best to enjoy our vehicles. A little bit of constructive dialogue is also part of this as well as we can hopefully agree to disagree. After all, we are all proud ISF owners right?
