We have classified the 46 complaints from 2004 Mazda RX-8 about ENGINE AND ENGINE COOLING into the following categories.
I bought my car around the first week of november 2003. in the first month i took the car back to the dealership three times for repair. the problem was with the engine. apparently one of the rotors was not firing causing a raw fuel smell to enter the car through the ventilation. with only 2000 miles, the engine was replaced after the third visit. two months have passed and after three days of no driving, the car will no longer start. *jb
I purchased my automatic rx8 in late jan. 2004. as i write this, i have averaged 14.3 mpg with mixed driving conditions (city and highway) during my first 3000 miles. my worst tankful was 12.3 mpg. mazda north america refuses to address my issue, which is: my fuel economy is well below the estimated fuel economy on the sticker. either there is something wrong with my rx8 or mazda has intentionally misrepresented the fuel economy of the rx8.

Although i followed the owner's manual instructions, the engine flooded after driving a short distance (1.5 miles) and turned off. engine was flooded when i tried to restart approximately 15 minutes later. said to be a common problem with the new mazda rx8s. tempature was 19. this is the second time in 6 days in very cold weather. this would be areal safety issue if it happens in a remote area.*ak
