Just to let everyone know.. I had my 2004 Mazda RX-8 in the shop on Saturday because it wouldnt start..My car has 42,000 miles on it.. As it turned out.. The dealership told me I needed updated Plugs as well as a starter.. The starter is much stronger than the original one that was in the car.. SUre enough.. once they put the updated plugs in there as well as the updated starter.. it was easy to start..Mazda paid for everything being that theres a 4 yr 50,000 mile warranty on that particular car.. they also did some AC work for free as well as my car wasnt cooling sufficiently.. PLease call your dealership and schedule an appt... By the way.. Mazda gave me great service on the day I came in around 12:30 on SAt... I Didnt have an appt but they worked on my car and had me out of there by 5pm .. I was impressed as it was a very busy service day and I was expecting them to tell me that they couldnt get to it.My email is tlang60736aol.com if you have any other questions.

your story sounds exactly like mine- i have a 2006 rx8 and i have had the car in to the service department 18 times in the past year with the last one being that i needed a new engine! well like you i went to the dealership to see about just trading straight across for a new one with out losing any money-well you know how that one went. and just when i thought i was going to be stuck with this brand new worthless car someone told me to go to my state's lemon law web site-i live in az- and there my prayers were answered- iam in the process of getting all my money refunded and they can have the car back-check with your states lemon law web site-it sounds like your car falls right under that law- good luck

Sorry to hear about the RX8 problems....You can get one of the few remaining Crossfires for $13-15,000 under sticker right now....they come with lifetime powertrain warranties....performance #s are virtually identical to the RX8s...+ top speed 151, I ave 24 mpg.....heated leather....homelink...esp.. buildt in Germany....by Mercedes! My 07 6speed is an absolute joy to drive!!! Production stopped on 12/17/07....76046 were buildt total ....maybe 50k came to USA.

Actually, the Crossfire was built by Karmann, not Mercedes. It has a combination of previous-generation Mercedes C-Class and Chrysler parts (about 50/50).
While the RX-8 is one of the purest sports cars on the road, the Crossfire is more of a GT car. Although it's undeniably a fine car, I don't think the Crossfire really compares to the RX-8 from a sporting point of view - plus, it doesn't have a back seat.

I just thought I'd throw that out there for anyone in the market for a new car soon...it's a fantastic bargain right now ....Daimler & Chrysler have parted ways & it didn't sell well partly cause they had real high sticker prices....mine's sticker was $36K ....I gave less than $23K. for a 6 speed Limited....some people are getting even better deals...
Trust me....it's so solid & fun to drive.....with the lifetime powertrain warranty....it's a keeper! My guess is there are less than a 1000 new ones left (worldwide) & most of those are automatics......

My 2004 AT with 37k has slowly acquired a vibration when in gear and stopped. You feel it in the brake pedal,steering wheel,doors, and you can see the vibration in the mirror's.Dealer said that their scanner/computer show that everything is in the NORMAL RANGE LIMITS....... The motor mounts have been checked and show no signs of wear.
The trailing plugs and coil were replaced along with the leading plugs 2 weeks ago and has not helped to negate the loud vibration. I only feel it when stopped.
Any ideal's or recommendations of RX8 dealer's in N.Cal. bay area ?

I think I replied to a reduced version of this in another forum, but now I have more information.
I have this same exact problem with my 2006 AT. My original dealer gaves me the same BS line about it. I went to another dealer, and they replaced my engine mounts. That worked for a little while, but then it came back. I have now gone through 7 sets of engine mounts in 15K miles, and now there isn't any difference after I get the engine mounts - the problem still exists and seems to get worse with time. The problem was worse when my AC was turned on, so once they replaced my mass air flow sensor and that problem was solved, but not the overall problem. My car also "stumbles" from time to time when I put it back in gear from neutral at a light. Try puting your car in neutral at the light - the vibration should stop or be barely noticeable. Mazda had a regional rep come out to look at my car, and his solution was to give me my 7th set of motor mounts. The vibration was a little better for about 10 feet, then it was back and worse than ever. One of the service managers at the dealership confessed that certain 8's do that and they don't know why - others are fixed by relacing the engine mounts. It is maddening to me.
Sorry I don't have a solution, as my car was never fixed. I also had a slew of other problems, so my solution ended being to sue under my states "lemon law". I am in the process of settling with Mazda now.

OK, here's my solution the vibration issue that I used in my 2005 RX-8 AT with 38K miles. The solution may be unacceptable for some, but for me, the solution provides far far more driving fun on top of minimizing the idle in gear vibrations...
1) Don't use the full automatic in city driving. 2) For 20MPH use only 1st gear. 3) For 35MPH use only 2nd. 4) For 45MPH use only 3rd gear.) If you are traveling highway speeds above 65MPH full automatic is OK.
The above strategy keeps the RPM level around 3000. After the first year of driving I began to notice that full automatic in city driving would constantly dive into 3rd or 4th gear, clearly lugging the engine creating a jerkiness in the over drive gearing. With the engine seeking the lowest gear at the first opportunity, I also noticed dramatically rougher idle. The rough idle appeared to go away after driving a long highway trip where RPM tended to remain above 3000 for long periods.
I believe there are two things going on with the RX-8 AT. The engines simply need to run at least at 3000RPM to keep everything clean and clear. Second, the electronics have a bit of fuzzy logic which will attempts to over optimize at low RPM speeds, producing more idle vibrations. The fuzzy logic controller remembers ten of thousands of previous gear shift behaviors, so it takes a while for the electronics to be retrained to new behaviors. Or just re-flash the PCM.

It is also widely considered to be a good idea to run a rotary to redline fairly frequently to prevent carbon build-up (and I believe to get the apex seals lubed up a bit more). I try to redline mine at least once every day that I drive it.
Just make sure it is really warmed up before you do this. At the very least don't drive it hard until the coolant temp gauge has reached the normal range. I also have an aftermarket oil temp gauge installed, and the oil doesn't get above 120 degrees until a few minutes after the coolant temp reaches the normal level on the gauge. I'm not sure at what temp the oil is safe to run hard, but I wait until that needle moves some.
