That is what the warranty is for. Do you think every mechanical product is perfect? They aren't. The only reason why Toyota and Honda don't have their dirty laundry advertised is because their marketing has more dollars to cover up the issues with commercials that trumpet their reliability and quality. Take a good look at the actual recalls Toyota had last year and the year before and you'll see that they are no different than any other car company. Rest assured the same struts, same electronic components, same motor mounts are used across all lines of cars. Look at consumer reports and you'll see issues with particular cars that used the same part from Nippon-Denso or Delphi.
I feel for your issues but it's the law of averages. When you're dealing with products being manufactured in the hundreds of thousands with parts fabricated in the millions
at an affordable price point there will be failures. No way around it.
Now if the majority of people on the world want to go and buy cars that cost $50,000 to build, then maybe those failures will be reduced. But you know what? Consumers don't want to pay that price. We want sales, we want some perceived "value".
There's no such thing as a free lunch. People expect it. But even NASA has failures.
Personally I think you'll see fewer problems, if any, with your MS3 over the next 26,000 miles. When my wife and I purchased our Mz5 it was part of the exhaust recall and had issues with blown struts and defective emission parts all in the first 10,000 miles. It was annoying yes, but my dealer always fixed the issue once (unless the second part failed) and always made the process as painless as possible (rentals, discounted oil changes etc). Now the Mz5 is approaching 50,000 and is as solid as a rock with zero issues overs the last 40,000 miles. I fully expect it to go beyond 100,000 without much drama.
Then again I've been a loyal Mazda owner for close to 20 years and never once had to worry about being stranded with a lemon. ON the other hand I've owned Toyotas and Hondas that broke more often and had pathetic service than you would expect given their advertisements.
I know it's a royal pain in the ass when your transportation breaks but try to keep things in perspective.
