    FYI..consumer reports recomends the RX8 in its 06 edition, and it has a highest rating for the following categorys
    Engine
    cooling
    tranny
    drive system
    fuel
    ignition
    electrical
    AC
    suspension
    brakes
    exhaust
    body integrity
    power equipment
    body hardware

    it had an average rating for paint,trim and rust,
    overall used car verdict above average, new car verdict average.

    The 04 (what i own) had trouble spots with
    fuel
    ignition

    below average with AC

    and average
    Electrical
    engine
    body hardware

    Bottom line is that if you take care of the vehicle you are more than likely not to have any more problems than you would on any other car. the sheer enjoyment of the car more than makes up for the extra TLC needed to keep the car going strong

    Tried the recovery procedure for a flooded engine (which I know it is), and it still won't start. What do I do now? HHHHHEEELLLLPPPPPP!!!!!!!! :cry:

    I gave up and had the car towed to the dealership. They said in order for them to get it started they had to:
    Put a battery charger on
    Push accelerator down for 10 seconds (to engage engine), let off
    Then turn key over until engine turns over, however long it takes (hince the battery charger) don't stop until it works and don't repeat (you'll flood the engine more)
    They say it's hard on the starter and battery, but it's what must be done.
    Installing trailer spark plugs and hot? battery helps it from flooding in the future.
    Now I hope this works if I have to do it at home!
  • OMG What a pile... This car loads up with ease and floods in 2 seconds flat. I moved the car from one curb to the other and it would'nt start after that.
    Problem? Ya new dealer plugs which are a whopping 50 dollars each! that 200 dollars just for plugs!!! Purged the engine of all fuel and cut off the fuel injection. cracked it over about 10 times and blew it all out. Then blasted the engine with starting fluid and then insterted my shiny new spark plugs. cracked it over for about 5 seconds and she fired up and runs fine now.
    Scary for a 2005 with 50K

    Just a note:

    My 2005 RX-8 has always burned very, very litte oil--like one quart every 3000 miles--and I was understandably concerned. I knew it was supposed to burn more (by popular report), so had it checked.

    One dealer in Memphis checked it and prounounced the car "fine", but three weeks ago as I was driving to work (75 minute drive) it gained a dead-spot. I gave more gas--nothing--gave even more gas--even more nothing. :confuse:

    When I arrived at work, I shut the car down and called my husband. He called the dealer I prefer and they drove the four hours to come haul it back to the shop. After three weeks, the shop manager (one of my new best friends) called us into his office to break the news that it had "internal engine failure". :sick:

    It wasn't anything to do with the weight of the oil or how I drove it. It wasn't any actual flaw in the engine. Most likely, it had to do with the small amount of oil it was burning compared to the amount it needed. I know now that there was a service recall to adjust the oil/fuel ratio.

    I have NOT received ANY service bulletins/recall notices on my RX-8 since purchasing it brand new in 2006.

    Keep an eye out for service bulletins/recalls by checking the core Mazda forums at:
    http://www.coremazda.com/forums/mazda-rx8-technical-service-bulletins-tsb/

    I am registered on the mazdausa.com site---which never showed any recalls or bulletins either.

    If it hadn't been for the Core Mazda Forum, I would never have known about the original drivetrain warranty extension to 60,000 miles, or the one posted this last summer updating the drivetrain warranty extension to 100,000 miles. I certainly never received it by mail or email. :cry:

    I now have a PDF of the document if anyone needs it. Email to mcneelyhomestead at yahell to get it sent to you. I hope you never need it--may your car be blessed by the rotary gods!

    After meeting with the Dale, I traded my beloved RX-8 in on a Mazda Tribute....they "gave" it an $8000 value. I wish the very best to everyone here. I loved my RX-8.

    With affection,

    Deaun

    Hello there;
    I am new but reading the previus Post I am wondering if some People have a agenda other then help others.

    I am thinking of purchasing a new RX8 soon, have done a test Drive and think the Vehicle would make a nice present for my Wife.

    I am a bit more then just Mechanicaly inclined so I do not buy the argument with flooding the Rotary (Wankel) Engine. Sorry Folks but that sounds just bogus to me. Even if you would have one wet Sparkplug so what the others would be fine and the Engine should fire and with a few revolutions the previusly wet Plug would fire as well.

    Buying new Plugs becouse the present one is wet, think again. Do you Buy a new Windshield when it is dirty or what.

    Would apreciate to hear from anyone with veriviable marked research concerning these particular engines for the RX8 thank you and By for now
  • have a 2004 rx-8 and it is sputering out of first gear and i when i get it to go i high rev it and the engine light start to blink i dont know what it is can some one give some help so i dont fix the wrong thing. :cry:
  • I have a 05 rx 8 bought it used 8 months ago. Im in the Marines in N.C and travled home for the holiday on my way back to N.C car lost power and engine light started flashing.Had to get it towed 137 miles to dealer. they said plugs were melted and one completely cracked and had to change coil too...but they say its my fault? Should i argue this or just pay the 600$?
  • Why did they say it was your fault?
  • they said it was maintance....so warrenty doesn't cover this....how is a coil related to maintance? Not to mention I have only had the car since May and I do get the oil changed, every 3000 to 3300 miles!
  • I am sorry, but I would need a little more detail. Your coils are not maintenance related. Maybe warrenty, but you would have to check. Anyway, the plugs are $150.00 on a good day. Not sure about the coil. If it was me, I would press the issue on the coil. Maybe also the plugs. I wouidl just need more info.

    Flooding happens, the water sits on the plugs and new ones are needed. This only happens in cold weather, I was told if the engine is not warm the engine floods, so to prevent this, if you are moving the car from the driveway to the curb (or a short distance) take the car up to 5-6 rpm then shut it off, otherwise you flood and ur starter engine could go...

    1,000 bucks later im wondering why no one ever told me...
  • The last two winters, a few days after big snow blasts here in Boston, my horn would start blasting randomly. I would punch the steering wheel and the blasting stops for a while, but then it would start again. Last year, I just pulled the horn fuse to stop it. When I ask the dealer to look at it, they couldn't find anything.

    Then after another snow storm, the engine light came on and stayed. Took RX-8 to the dealer who said the diagnostics showed an air intake control error. It tested fine on the diagnostic machine, so I didn't need to replace the $500 air intake control. The dealer said it could happen again though.

    This year, the engine light went on again and the horn started blasting within days of each other, after the first big winter blast. I didn't pull the fuse and didn't visit the dealer because I figured that things would fix themselves again. After a week, both problems went away.

    So my question is, where is the most likely place for the horn and the engine check light circuits to be exposed to the winter elements? Or is a heated garage in winter time the best bet?
  • Well I'm not sure about that...would try a garage to see if that helps. The dealers only say and do what they feel. I got screwed...nothing was covered i had to pay the 500.00.....let's see if they fixed my promblem! Good Luck with urs.
  • I had the same problem and I replaced the Ignition coils. They are known for going out in these cars as soon as 30,000 miles. You can replace your self and save alot of money. All you have to do is remove the air filter housing by pushing forward with excessive force then lifting it out to acess the ignition coils. You can purchase online for about $34.00 each with shipping (4 total). I relaced mine within 15 minutes. If you would like more details look me up on here.

    I am having warm engine start problems now with my Rx-8 and am wondering if it is the starter. Does anyone have any advice out there?
  • OMG wish I had known this....my son just had coils replaced in his Mazda RX8 at 32k miles and cost $703!
  • My son purchased a 2005 Mazda RX-8 brand new. He did all the research, learned about the rotary engine and its quirky letting it warm up regime before moving. He now has 32,000 miles on it and has had it in the shop 2 times in 12 mos at the tune of $1400! The first time, they blamed him for the carbon in the engine and replaced the battery and it barely squeaked through the compression test. The man told him he would probably end up needing a new engine because these are defective. Six months later, it started, then lights came on for the engine, and had this odor, and then would not start. Took Mazda road side assistance 2 days to come tow the crap. They told him carbon in the engine and needed new coils! Cost...over $700! People, Mazda extended the warranty on the engine which is defective and they know it! YET this engine causes other problems which are not covered and are costing people hundreds and thousands of dollars. Don't you think it is time that Mazda quit beating around the bush and giving Mazda RX8 owners the run around and recall this hunk of junk? They had the audacity to say this car is not for short distance driving. Hello? Was that disclosed on the sticker on the window? Do you know how many people would have bought these things if they were told they would need a new engine at 30,000 miles? After many calls to Mazda HQ, they also give the run around. They paid for the decarbonization by the way. Big freaking deal. In the meantime, car floods, runs rough, has no power, and probably would serve better as a boat anchor.

    I think a letter writing campaign is in order and maybe the major news station and consumer advocates should be made aware. How about it?

    hi i just like to know if you get the problem fix, and what you did to get it fix i am have similar problem with my car i have in a new battery and new set of spark plugs the car will run and idle OK but it will only start when the engine is cold, when it start and and it warm up and u cut it off it wont start on till it cold some time it take hours to get it back up and running again plz help
  • We bought our son an rx-8 and didn't know about all the problems. He had it for about a year, then the engine wouldn't start. We took it to the dealer. By now, Mazda had extended the warranties on the engine and they put in a new one free of charge. This was in April, 2010. Yesterday, the car made horrible sounds and lost power. We had it towed into the dealer. Guess what. We're getting yet another new engine. This will be the 3rd engine on this car. Maybe this one is the charm, or better yet, maybe we need to trade it on one something more reliable! I'm thinking the latter.
  • hello there
    afta replacing the ignition coils was the car fine after n did the odor go away,..is this why the engine light is on???
  • Aww man... damn I need to get my first car and I've been looking for a good car that will take me to school and work, and I fell in love with the Rx-8, but from what I see, its not a very good car at all....

    can you tell me what exactly the problem is with the Rx-8 according to what you know please?

    can you also tell me how long and how much you know about the Rx-8 rotary engines please
  • i am having the same exact problem with my son RX-8 and the dealer is now getting a new engine for my sons car and i totally agreed with you. MAZDA is selling a lemon car.
  • I just bought my son an 08 RX8, are these problems occuring on this model also?
  • Not sure, I would check online to see but I think that all the RX8 have the same issues.
  • Wow!! I guess I should have done more research before buying. You would think it would be fixed by now....
