8060 0 plastic fender around right front wheel popped out of alignment again, same as previous problem. 
10540 0 transmission chip reflash, car shifts more smoothly now; recall Front passenger side fender coming loose at joint near front headlight. Told to take to a body shop as cause is likely a broken clip inside. Dealer pushed panel smooth but warned it would likely pop out again until I have the clip replaced. 
19840 75 Headlight bulb on driver's side out. The manual says not to try and replace it yourself, then gives directions on how to do so, so I tried it. Don't. You must remove the wheel to access the bulb via wheelwell. Ridiculous design. 
22940 309 Remote wore out, needed replacing. Dealer said it was just batteries, charged me 22 for labor to replace batteries, one remote still didn't work, replaced under warranty. Now the key falls off the remote. 
28520 100 Mazda exhaust system! A 5o cent bolt holding together a gasket connecting muffler to exhaust system broke. Dealer charged one hour labour because they had to punch out old bolt. One hour labour to replace hibeam/daylight running lights. When one burns out, neither side works.
