“I had many recalls done last year. Now, today, oliver at Mazda corporate said that joe machens dealerships aren't equipped to have done the work properly. Recalls: 16v793, 17v-354 & 355, front end stearing from inappropriate caulking of ball joint , engine replaced twice, oil mixing with coolant, again, and now my alarm goes off as soon as I start it. Joe machens told me to remove the battery. A new lithium battery is being developed by Mazda because rotary engines can't use a regular battery. …”

“**resubmit-didn't go through** I was driving approx 65 MPH on the freeway and felt a kick/jolt and had a loss of power. My speed went down10-15 MPH and although I tried to accelerate it wouldn't do anything. I pulled over to the shoulder and tried to exit but car refused to go into gear. Every time I forced it into gear, the car would constantly stall and die. I had the ignition coil and spark plug replaced but now the clutch just sinks to the floor. I've tried to pump the clutch to get it into gear but this is quite dangerous on the road. …”

“Failure of clutch pedal assembly. A plastic plate cracked and caused an irritating plastic binding noise, ever time I released the clutch pedal. This apparently happens a lot, sometimes it is fixable but in my case I had to replace my entire assembly, as I was told if it completely cracked I would lose the function of my clutch pedal. Failure of the passenger side power lock actuator. I have read many accounts of this part failing. Usually blamed on hot or cold claimant, however mine just failed earlier this week, with weather in the mid 40's. …”

“I'm going in today for the third time because my AC continues to make a noise when the fan is blowing. I cant even begin to list all of the problems I've had with this car. Just to name a few I'm on my second engine, new brakes, battery and tires before 40k miles and I was told by three different shops that something is really wrong with the brakes but Mazda claims other wise. I've had a two new radiators and my driver window went out along with everything else from the visor falling off during the hot summer because it just melted. How does a sun visor melt. …”

“The Mazda RX-8 is having an issue that is coming up more frequently now from a faulty A/C switch or heating system failure. The heat does not come into the vehicle when the heat is turned on and only cold air comes into vehicle. The failure happens in the beginning only randomly until the unit completely fails. The A/C modular is a electronic switch that changes vents and A/C or heat. The vent mechanism still functions but the heat is never transferred into the vehicle. …”
