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 Recalls (Recent)

Body, Interior & Misc., April 11, 2013

RepairPal Expert Overview:

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

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 talked about the door would not open using key, remote or handle.

I have a 2004 RX8 and it is disappointment in all aspect. I have been driving RX7s all my life and I've never have this kind of PROBLEMS. After driving it for 6 years, now its just
sitting in my garage collecting dust. I've alreally spent a lot
money on repairs. MAZDA, THIS IS THE REASON WHY YOU CAN'T BEAT
YOUR COMPETITORS! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

YOU DON'T EVEN DESERVE ONE STAR!

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 to work without any luck. We go into the dealership to sign the paperwork and leave to head home and you'll never guess what...on comes the engine light! Imagine that! Ok, again (I know, I must have REALLY have loved this car right?)

So we traveled home, four hour drive home with no heat! Again, thinking it was going to be a simple fix.

WRONG, WRONG, WRONG...I put on new rotors and brakes, noise is still there. We recently had the vehicle inspected and was told that the noise is in the rear end and not the rotors. :(
The heat control unit blows cold air on cold days and hot air on the hot days. The air pressure sensor light is on, the air bag light is on, the headlight leveling sensor is on...what a train wreck! I only have a few more lights that are even left to come on.

It makes me wonder what kind of hell this car has been put through. It will cost me a fortune to fix it all. I think walking away from this mess at this point would be the best. I am scared to think about what it will take to make it run as nice at it looks. It is a beautiful car! :)

Everything you read on the internet about things that can go wrong with these cars, there you will surely see a picture of my car!

Good Luck to anyone with the same kind of drama I have going on...Anyone want to buy a car?????

Beautiful and prestigious car but to unreliable and costly to maintain
