Appreciated reading your concern and would like to help. I'd like to confirm a few things with you to make sure we're on the same page however. Maytag does provide a 1 year, limited warranty on all their dishwashers. This is covered in detail within the owner's manual. There's a badge placed upon the front of the dishwasher advertising "Maytag's 10 year LIMITED PARTS warranty." Beneath this stamp it should clearly display "Motor and Tub." Is this all correct?
If this is the case, I fail to see where the manufacturer has done anything wrong. Generally when you purchase such an appliance, you have the option to purchase extended service guarantees. Some people care about this issue; others do not. Maytag, being part of the Whirlpool family of products, is an easy brand to have serviced.
