Crack in rim...covered by warranty???
Thanks to all who reply.
If you're a REALLY good customer and you throw a big enough tantrum then you might get the dealer to do something for you, but other than that I think you're probably out of luck.
I agree with the other poster that you will strengthen your position if you can find a reputable wheel shop that will state in writing that the crack is due to a manufacturing defect.




MB have a big corrosion cover - check if you can see any ... a crack may be treated differently unfortunately.
That wheel never balanced out right after that....you always could notice a high speed vibration beginning about 70 and getting worse as speed increased. Took it back umpteen million times, but it was still messed up when I traded the car a year and a half later.
Depending on the size and location of the crack, you are going to have balancing issues if you get it welded.

I could give a 50 page dissertation on weldment to a rotating element, save your self the trouble, get a new rim.
Does welding on a rotating element pose any additional problems aside from the fact that the wheel must be re-balanced when the tire is installed?

Welding on an aluminum rim has many draw backs, most are heat related.
Any time you weld aluminum it changes shape and molecular properties.
The change in shape means a rim will expand during weldment and freeze in a new shape (no matter how many heat sinks you try to use) now the problem is that it can be balanced but will still cause vibrations like an out of round tire/wheel.
The molecular changes are the anneal-ment of the metal that takes place during weldment, the heat changes the hardness/temper of the alloy and will actually make the rim crack easier in the same place after it is welded.
In the case of your hole in the rim, a weld could be done on a small scale with a plug and 4 passes with a tig and letting it freeze between passes. In the case of a crack, a much larger area is covered, and unless you X-ray it you never know how far to go. It is just soo much better to find a new or new take off rim.
In the end we have some seriously fast cars here, lets try to stay safe as possible, I would hate to hear of a wheel failure at speed by any member here.
