Four problems related to engine shut off without warning have been reported for the 2004 Mazda RX8. The most recently reported issues are listed below.
I've been having a couple of incidents where my safety has been in danger because my vehicle suddenly shuts down in middle of road. Last time happened in a middle of an intersection, but it has happened in curvy uphill roads and highways, where I have been exposed to accidents because engine shuts down. I am more than concerned because its not just my safety but the ones traveling with me and the ones that not. Mazda has acknowledge the problem with the engine of the 2004 RX-8, but in the dealership they always make something up not to check it under warranty. I need your intervention to deal with this issue. I have almost been involved in accidents because of this problem. I have found about the recall in this website. I have lost money, and time but not willing to risk my life. I need to know what steps to take action, because all they do is deny that's its warranty related even when they know about the recalls that related to this problem, all they do is sell you spark plugs and ignition coils (which they say is the cause and never solves anything but their sales). This has to stop. Its not fair to pay so much for a 2004 car and get back such a nightmare. I need to know what to know if I can get a remedy under federal laws of transportation safety. This is serious.
Owner of an 2004 RX-8. The vehicle had 8,000 miles at time of purchase. Within 2,000 miles of driving the vehicle, while driving down the interstate the engine shut down. Mazda replaced the sensor system. They stated that the key became unprogrammed while driving? the car was worked on at prebel Mazda in georgia. My car now has 26,000 miles. I take very particular car with the maintenance of the car. Last Friday night, I shut my car off and it wouldn't restart. After some research, I have found that most all RX-8 Mazda's have this similar issue. I am currently paying out of pocket, to have test run to determine the problem. There is a big chance that the vehicle will need it's engine replaced. Due to a recall "compression" issue by Mazda. I am very upset that I have a vehicle with major manufacturer defaults.
