2004 Mazda RX-8 Problems
If the climate control's heat/cold knob is not adjusting to the desired temperature, a new climate control unit may be needed.
Hesitation and/or a lack of power can be caused by the secondary shutter valve (SSV) in the intake manifold becoming stuck open due to carbon build up around the SSV shaft. This may occur with no Check Engine light illumination but eventually the light will illuminate with code P2070 (Secondary Shutter Valve [SSV] stuck open). The cleaning procedure described under the service bulletin is a long process and it is recommended to install the updated SSV actuator and gaskets. The SSV is activated at higher RPM and the carbon accumulation can happen when it opens infrequently. The effects RX-8's built before April 18, 2007.
I noticed about 50,000 miles the radiator light would flicker on and off. The engine temperature alwys stayed in the normal region and the radiator was full of fluid. The Mazda repair guy told me that this is accuring in a lot of the RX-8s. There is a plastic waffer on the gauge ball inside the radiator that measures the fluid. When the waffer starts breaking up, the gauge ball starts fluctuating greater sending a signal that the radiator is l...
2004 Mazda RX-8 Questions
The car jerks when going from 1st to 2nd gear and when changing it from park to drive and reverse to drive. I had the transmission oil checked and it was fine.

2004 Mazda RX-8 Recalls
This limited regional recall is for vehicles currently registered or first sold in southern Florida, along the Gulf Coast, Puerto Rico, Hawaii, Puerto Rico, Guam, and Saipan. Upon deployment the passenger airbag inflator could rupture, increasing the risk of personal injury. Dealers will replace the passenger side air bag inflator to correct this concern. Note: this supersedes recall #14V-344.
This limited regional recall is for vehicles currently registered or first sold in Florida, Puerto Rico, Hawaii and the U.S. Virgin Islands, and equipped with Takata-brand air bag inflators. Upon deployment the driver and/or passenger airbag inflator could rupture, increasing the risk of personal injury. Mazda dealers will replace the affected airbag inflator modules to correct this concern.
Airbags use a chemical reaction contained in an inflator module to create the pressure necessary to inflate the bags when deployment is required. These vehicles are being recalled because the front passenger airbag inflator may produce excessive internal pressure when deployed and as a result, the inflator module could rupture, causing metal fragments to strike vehicle occupants. Dealers will inspect and replace any defective passenger front airbag inflator module found.
2004 Mazda RX-8 Reviews
Beautiful and prestigious car but to unreliable and costly to maintain
I bought a 2004 Mazda RX8 Grand Touring this winter. The car is beautiful but...where do I begin? When we tried out the car, there was a noise coming from the rear end. We assumed that it was just the rotors since the car had been sitting for a while; rusted and just needing running. So, during this test drive, which as I mentioned was in the winter was very cold. We tried to get the heat...
I love my car. I have a 2004 Mazda grand touring edition rx8. I have 196,000 miles on it. This is the original engine. It still looks and runs like it is brand new. I am just now replacing the original clutch. I too have had some of the issues listed but not as many. The only major things that I had to replace is the water pump and the drivers side door handle because like another person tal...
