Product review (3 stars): We would recommend having a local certified technician in your area properly ...
Update:

Received product and installed. Couldn't have been easier thanks to a Youtube video that walks you through the entire process. Helps you get it right the first time, as the printed instructions are difficult to read/follow.
This kit did come with a small Torx15 head that you can use in conjunction with a phillips screwdriver, so there should be no reason to buy a separate tool.
My only beef is that one of the metal adjuster arms came without wheels. I had to remove the old wheels from the original and install them on the new arm. This kit only has 12 parts and 4 screws. You would think they could get this right. I'm knocking off 2 stars for this- there really is no excuse. It's bad enough we have to go through all this to begin with, but to have replacement parts be incomplete just rubs a little salt in the wound.
Anyway, my overpriced, under-engineered dishwasher is functional again. Total time was about 20-30 minutes.
The kit works and wasn't difficult to install. We'll see how long it lasts.

I have ordered this, and though I have not received the product yet, all indicators are that it will solve my problem. I'll update after receipt and installation.

Just thought I would share today's exchange with the Customer Service rep from KitchenAid via online chat:

  Marcos O.: Thank you for contacting KitchenAid!  How may I help you?

XXXXX: I have a dishwasher KUDS30ixbl8 I bought from Lowe's in Owasso, OK a couple of years ago. The top rack has broken off ( the pegs that go into the wheels). I understand there is a recall or extended warranty to replace these parts with a metal substitute. This part was poorly made and degrades with the heated drying. What can you tell me?

  Marcos O.: I am sorry to hear of the problem  with your appliance.  Based on your model number for your appliance, there is no recall for your appliance. We would recommend having a local certified technician in your area properly diagnose and repair  the issue you are experiencing.  You may go to  https://www.kitchenaid.com/customer-service/schedule-service/ or call (800)422-1230 Monday-Friday, 8:00 AM to 8:00 PM EST to schedule a service appointment with a local certified technician.

XXXXX: I can order the part and do it myself. I just wanted to see if KitchenAid would stand behind their product. This is a known issue and has resulted in substantial negative reviews all over the internet. Unfortunately, I also purchased a KitchenAid double convection oven that is sub-standard, and has had to have repairs by a technician. Thanks anyway.

  Marcos O.: It has been my pleasure to assist you today.  Should you have any further questions or concerns, please do not hesitate to contact us again.  Thank you for choosing Maytag, we appreciate your business.  Have a great day!
  Marcos O. has disconnected.

So in other words, it's been there pleasure to sell me an overpriced, substandard dishwasher that they have no intention of standing behind.

I feel better now until I have to go home and look at it again. #FLEECED
