Manifold/header/muffler/tail Pipe Problems of Mazda RX8

I purchased my 2004 Mazda RX-8 in March 2005 and problems with the check engine light coming on did not start until April 2006. At that time the car had approximately 26,000 miles on it (I have a long commute 90% of which is freeway). The first several times back to the dealer minor things were adjusted or cleaned such as the spark plugs and a small valve a kit to a butterfly valve in a carburetor engine. Eventually the valve was replaced, but the light still came back on. In fact, on one occasion the car was pulled out of the shop doors pronounced fixed and upon my starting it again the light was back on. Eventually Mazda approved that the intake manifold be replaced, which it was. The check engine light has stayed off since that replacement (about 3-months) , but other problems have arisen. First, either the intake or exhaust heads were not sealed correctly since the engine sounds like it is coming through the dash. This has been pointed out but never properly repaired. Now, as of August 3, 2007 the car's electrical system completely shuts down. This has happened on 3 occasions where without any warning the car shuts down. The needles in the dials on the dash bounce wildly back and forth while a clicking sound is coming from the fuse box in the engine. Needless to say the car is back in for it's 10th visit to the Mazda dealership in cleveland. I have started the buy back procedure with Mazda.

Hi, I purchased my 2005 Rx8 new in December of 2005. I have 38000 miles at present time. My vehicle has been towed three times due to stalling. I have had my vehicle in for all recalls and it has passed all test. I am still having problems with engine stalling while driving. My vehicle also back fires at times blowing black smoke from tail pipes. I have serious concerns over the safety of my vehicle due to the known fires caused by the rotary engine. I have phoned and visited many dealers to see if Mazda has issued a buy back or trade due to issues with the Rx8 and they have all replied with "sorry, but we can sell you a different Mazda at retail". I have had my vehicle to the Mazda repair shop so many times that I no longer even bother to take it in because I always get the same answer. I really just want my car fixed or something else to drive that is safe. I think Mazda needs to recognize that there is a real safety issue and peoples lives are in danger. The issues with my car are so many that I do not like to drive it. Currently the check engine light stays on. Please feel free to contact me for further issues with this vehicle.
