What owners wrote

A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.

There is contamination in the oil. So much so that it is impossible to check the oil. I've gone 3000 miles and never been able to check the oil. Even after wiping the dipstick, simply putting it back recoats the dipstick, so that the oil level cannot be read. The dealer simply changed the oil, but did not fix the problem. They said mazda knows about this, but won't do anything about it. All letters to mazda-USA are ignored. Why does mazda ignore such a potentially serious hazard?

Hi, I want to report a control arm failure on my 2004 mazda rx-8 that resulted in an accident and minor injury. I was driving the car on december 7 in oklahoma city and after completing a right hand turn at approximately 30 MPH, I was accelerating away when the right front control arm separated at the ball joint resulting in loss of control. The car spun around and went over a 10" curb with all four wheels and struck a highway sign.

I typically drive my rx8 like it should, one day I come home park my car per usual. Next morning I go to turn on my car, the dsc light stayed on, thought nothing of it, then on my way to work, I was driving causally, then while in the middle of a turn, my steering became very heavy and almost impossible to turn, my power steering had went out.
