They are definitely garbage. The lugnuts are steel, but they're covered with a softer "jacket" for appearance. This eventually bends/warps/swells, and looks like crap.
I had my Aspen at the Chrysler dealer on Saturday for some routine maintenance, and they brought me back to the service bay to show me the poor condition of the lugnuts.
They then told me they'd be glad to replace them for $16 EACH. I laughed and told them they are crazy, and the parts guy agreed that the price was ridiculous. They offered to go down to $6.75/each, but I chose to order some chrome lugnuts from ebay today for $23.99 shipped (for 20).
I was just amazed that they would point out the poor quality of their parts, and then expect me to buy more poor quality parts.
