Question about 2004 Mazda RX-8

My Mazda RX8 2004

For the past couple of months I have been at the dealer about my car driving bad. After driving the car and it gets hot it will drive bad and cut off. The Mazda dealer said that was a misfire. OKAY so the first fix the stenoid and I drove it home and to work abd it cut off again after it got HOT. It cranks up after 3 min or so. Then I took it back they had it for 4 days and fix the cad. convertor, spark plugs, coils, and other little things. When i drove it home and to work and it got HOT enough it cut off again. I took it back. They kept it 2 days and called to say its the engine malfunction. They are replacing it. I have seen many things oon the internet about a recall on the 2004 engine. All the things they fixed already I paid to get fix just to turn around and replace the engine. Can someone explain what the HECK mazda is doing. Do I need to get rid of my car because it I have also read a rotor engine is bad and high maintenance. I bought it from a dealer but not Mazda and havent had it a year. After I get the engine will I continue to have problems?

    Thanks for your comment. I have spent money for things I feel were un necessary just for them to say its the engine. When that should have been their first correction. They are saying they will replace the engine at NO COST not knowing I am aware of the engine and transmission problems the RX8 has. So my question is did I get things fix that has to do with the recalls and I should be refunded? I am not paying for the engine that I am sure is a rebuilt engine not a new one. But if I have paid for things that were part of what they are repairing now which is the engine than should I be refunded for what I have paid for thus far. In other words do need to call Help me Howard? If you know who that is.

I think it is related to the the ECM unit. Just gotta suck it up. My RX8 JDM 2009 cuts out regularly when I move the automatic gearbox to N and coast slowly up to the red light before I bring the car to a complete stop. My RX8 was brand new and fresh from the showroom. It had less than 5,000 kms on it before I got my first cut out. My guess is the ECM gets confused and cuts the engine. Difficult to replicate. Just happens without notice but does so frequently. Mazda deny it all and think I make all this stuff up. Will never buy a Mazda again.

    I have a Mazda too! It is old, though, and has needed a ton of repair. It's a family vehicle and so we're not going to give up on it too easily. However, we did recently replace the transmission and it's been running much smoother ever since.

I will never buy a mazda again. They have bad transmissions and engines. What is worse they use the same parts as Ford. How in the world do you combine a japanese and american parts into one engine? It keeps breaking down, thats what happens. I would ride it out since you are already gettin an engine but if you haven't purchased it, sell it and put that money towards another car, the dealer has used you like a gold digger.

My 2002 Mazda tribute ran hot. I found out my heater connection was broke. But when I replaced it. It still ran hot and now it taps real loud when the motor gets hot.

Need to discover why it is running hot to start with but not drive if it is causing the motor to get noisy. Overheating can be due to a thermostat stuck closed, cooling fan not turning on, low coolant level etc. Need to get to the bottom of the overheating before engine is damage badly.

Mazda miati will start but engine dies almost immediatly help

I recently replaced the fuel pump in my 1999 Miata. The way mine acted was it died as if it ran out of fuel and didn't even start up after that, just got a few combustions when trying a couple times then nothing at all. It still could be your fuel pump though. They go bad between 130k and 160k miles usually. Some just get weak so they pump fuel but not at high enough pressure. If that's the situation with yours you could do a flow check and see no problem while there still is one. You need 80-90 psi so if you can borrow a fuel pressure guage that would be a good place to start. If your mileage is anywhere near 130k then just replace it anyway because you'll need to soon enough. A while back one of the coil packs went bad and my engine would only run on 2 cylinders and then only when hot. Since there are 2 coil packs and they don't go bad exactly at the same time, your symptom is most likely not related to that. Check the main fuse.
Mine went bad a few months ago. It didn't blow but the inside of it kinda fell apart. I knew right away what it was when it failed because I was driving along and the engine sputtered, the radio cut on and off, all the lights flickered. If it's bad you'll lose all power to lights, radio, etc.
The main fuse is cheap and easy to replace so I'd recommend replacement anyway for peace of mind even if it's still ok.
Also there are other fuses for fuel injection and such that could be flaky or bad. Can't think of anything else. I'd suggest getting a spark tester so you can confirm or rule that out. Can't comment on the camshaft sensor, never had an issue with mine.
Oh, and as for fuel pump prices, my local Mazda dealer wanted almost $600 for one. I found many for around $100 on the interneet but ended up buying one from Rock Auto for about $32 with a one year warranty. So far it works just as well as the original. No loss in power or reliability at all. It's pretty easy to replace in Miatas compared to most other cars. Hope that helps. Good luck.

We have recently purchased a 2005 Mazda 6 Classic Hatch, up until recently we have had no problems with it, but at least 3 or 4 times over the last couple of weeks it has not wanted to start, it would...

MONTEREY, Calif. -- After suffering a black eye from disclosing that it won't count RX-8 owners' opinions in its internal customer-satisfaction scores, Mazda says it may have to replace the engines in many of its flagship sports cars.

The voluntary recall of all 2004 and 2005 vehicles, and some 2006s, is expected to be announced this week or next. It involves damage to the catalyst resulting from oil leaks in the RX-8's rotary engine.

Any engine that does not pass a vacuum test must be replaced, said Robert Davis, head of product development and quality at Mazda North American Operations.

Engines prone to failing the test are mostly in hot climates and use synthetic oils.

Mazda also will check each RX-8's battery and starter, which tend to fail in cold climates.

"We're going to give these cars the white-glove treatment," Davis said. "We would rather replace the engine than have the dealer crack them open."

Davis would not disclose the projected failure rate of the engines or the cost to replace them.

Mazda has a remanufacturing center in North Carolina that will rebuild faulty engines and return them to service.

The recall comes after a video Webcast by two dealers who attended the July 11-13 National Dealer Advisory Council meetings in Newport Beach, Calif., was leaked on the Internet.

In the video, dealers said problems with the RX-8 were unfairly lowering Mazda customer-satisfaction scores.

Mazda informed the dealers that RX-8 owners would continue to be surveyed, but that the responses would not factor into dealer
customer-satisfaction scores. See story here

Mazda has issued service bulletins on such trouble spots as squeaky
brakes and engine flooding.

it all depends on where the leak is and your text gives no hint. seems like you may have a couple of problems. this is most likely still under warranty so i would run these issues past a service department at a dealer.

My 99 cadillac deville ran hot about 8 months ago i took it to the dealer thay told me that i need a new engine and to drive it for a couple days and see what happen i have been driving it for eight months...

If you have no obvious external coolant leaks then the most likely culprits would be leaking head gaskets or warped heads. I would take the car to an engine rebuilding shop and get a second opinion to the dealer, not to say that they are wrong, but your engine may be salvageable at a cheaper cost and those guys would be better positioned to tell you that. Hope this helps.

MAZDA dealer replaced transmission under warranty

it sounds like the dealer has not fit the shifter cable corectly it may be sitting on a bad angle as you have all ready paid the money for the new auto and you expressed your concern when you picked the car up you should take the car back and demand it be repair properly don't take the excuse it is wering in car parts dont were in,
i am sorry this is not exactly wat you want to here as this sit is to help people fix things but some things you shouldn't have to fix eg poor workmanship
(also the truble may be in the selecting mecanism inside the auto in wich case it will need to go to spcalist)

Coolant fan not working- engine staying too hot

The fan might not be working because the sensor in the radiator could be bad.
