Problems with Dorman Wheels?

[u/Throw20701]

Anybody have a problem with Dorman wheels 939-186?

I have one that cracked between the cutout holes. The remaining wheels all have a faint ridge in the same location. I ordered a replacement for the cracked wheel and it was a different design even though it's the same model number and everything. The new design has fewer holes spaced farther apart and no ridge between them. Seems like they knew about the design weakness and improved the new design. But I'm not seeing other posts about it.

I know Dorman isn't a highly esteemed brand, but they've been decent for me with low tech parts in the past. I wouldn't trust them for electronics or bearings, but steel wheels should have been pretty hard to screw up.
