My cel was on almost right from leaving the dealership. Brought it back in and they reflashed it. I've had it for a month now, with 2800 miles, and my cel just came on again. Just my 2 cents. (If this keeps happening...I wonder if that falls under lemon law? Isn't it 3 times for the same problem?)

you must be talking about the now rescinded TSB which showed a different flash for california cars. even if they still go thru with a pcm scheme in this manner , the way it looks from the tsb you wont be able to go outside california to get it changed. you see it says flash x for all 2004 cars, flash y for fed/canada 2005 cars and flash z for 2005 california cars . that seems to imply that every US and Canada car would have x or y(2004 or 2005) but cali cars would have z(2005 cali rx-8s) on top of those so to tweak them for cali emissions mandates. no dealer would be able to "back flash" to remove z. or let me put it another way- it is possible to back flash a car but no dealer would do. especially , from what i gather, any dealer in Nevada.

i'm gonna go to the one in henderson. i went there today but the GM wasn't there, and they told me that he will be in there tomorrow. and i spoke with one of the women that works there, i think she is one of the sales managers, and she asked me if there was anything wrong with my car. and i told her all the problems, the engine flooded twice, third time this morning, my friend and i varely got the engine to start after ten minutes of jumping it, then the oil gauge doesn't work at all, the car shakes, check oil and coolant light goes on and off and i check both(sometime ok, sometime not), the ac doesn't work for ****, gas mileage is worse than claimed, and horsepower is less than what they claim plus when i bought the car back in june, they didn't have me sign a disclosure for that (horsepower claim over actual), plus they were supposed to give me $500 gift card because of that. i think i have a very strong case. if they don't want to take it back, i will have to go to consumer affairs and report them and i already talked to my lawyer and he said that i have an excellent case. but after i told the lady at the dealership all that, she told me that the GM was pretty new, he just got on board with them from pontiac and he is supposed to be really nice and that mazda is sopposed to be really good with this. i don't want them to fix the car, because a lot of people in the forum who had it fixed, had the problem reappear. this **** shouldn't be happening to a brand new car. it's been very inconvenient. don't get me wrong, i lvoe the rx-8, and there is nothing like a rotary, but they need to take it back. what do you guys think? anybody ever take a car back? any tips, advice?

First, no dealer would ever solve your problem of being "upside down" (i.e. owing more than the car is worth) on your current car. That's your problem, not theirs. Of course, they'll "pay off the entire (current) car" as part of your deal. You will notice, however, if you look closely at the deal that you will have financed the difference as part of the new car purchase.
Second, never, ever begin a discussion of a new car purchase with a discussion of your trade-in. Negotiate the price of the car first. Then discuss a trade-in if you have one. You'll quickly find that you're better off selling the car yourself than trading it. (This rule doesn't always hold; only about 99.99% of the time.)
Third, never, ever buy a car in the context of a discussion of what you can afford for a monthly payment. If you're looking at an auto purchase in terms of what you can afford from month to month, you're exactly the pigeon that an auto salesperson longs to see come through the door. This enables the salesperson to adjust the length and interest rate of a loan to maximize his/her profit and place you in the position of being "upside down" in the car you're buying so that next time you'll face exactly the same problem you're currently facing.
From your posts it appears you've been down this road before. That is what has put you in your current situation. If (a) you plan to change cars every few years, (b) are willing to pay for the privilege, and (c) your credit rating will support it, consider leasing instead of buying a car. At your current rate, you'll find yourself continuously digging a deeper debt hole for yourself.
And the first rule of holes is....stop digging.

i got the car in june of this year. i know some of these tips that you mentioned jsh, like never discuss a downpayment until you agree on the price, or never discuss how much you wanna pay monthly, etc. what i am concerned about mostly is returning the car.

What really amazes me is that at your young tender age you have the financial resources to buy an 8 in the first place. OK, let's put that aside for a moment. Assuming you had someone assist you with the financial aspect of the aquisition of the car, where the hell are they in helping you out with resolving your current problems?
Believe me I truly understand your problems in dealing with car salesmen here. I've only been in the states for 2 years but have had the unfortunate experience of buying 5 cars so far. (one of them being an eight). Car salesmen and dealerships in general are a pain in the ****, mostly here, but worldwide in general!! If you find a good one then you are lucky. If the dealer you bought the car from is reputable then they should be bending backwards to sort out your problems.
I truly hope you get it all resolved. I've owned rotary engined cars for over two decades and can honestly say that there is no better driving experience.

I agree for the most part but there are some people that are getting crazy bad MPG......at a level that isn't normal 10-12 mpg. They have a gripe....the others are just people that either didn't do their homework or just like to bitch.

I will note that on the current tank since they replaced the gas cap to fix the CEL that just a bit more noise is coming from the air intake and the rear wheels seem to want to break free a little easier. I know that they disconnected the battery at some point, because the clock was way off and I had to set it when I got the car back. Does any of this make seense?

now your ac- did you get the amplifier? mpg- have you given the car to them so they can verify the mpg? and oil guage- you didnt answer but the oil pressure gauge is an idiot light with a needle. it will only show 2 things- yo have presure or you dont. are you saying yours never shows any pressure? and the dealer can see this but doesnt fix it?

Latest Flash
So, I got a letter in the mail a month ago to come in for the latest flash (M?) to prevent hard starts in the winter. Not having hard starts I put it off. Last couple weeks, started having some hard starts, and brought it in last Friday.
No problems over the weekend. Then it got cold again...
Car started fine, but unless I let it warm up for ~5 minutes before driving it in the morning, I would get hesitation. I bring it in on Tuesday, they tell me, "Must be bad gas" and they check the OBC for error codes and I go on my way.
Next day, no hesitation, then on Thursday, get the hesitation back. Wednesday night, CE light goes on with no perceived problems while driving, and I bring it in this morning.
They call me up this afternoon, and tell me that the flash (when they did it) said it worked, but the error code being reported does not exist. They say they have called corporate, the engineers are off until the new year, and they assure me that the car is still perfectly drivable, and this isn't a big deal*. They also tell me corporate has halted flashes until they investigate this.
I call BS on the drivable thing, so I have a rental until the new year.
Since the computer seems like it controls an awful lot of important stuff (timing, richness, etc) I think it is probably a bad idea to assume the program is good. Given the info that they gave me.
Besides, lets say the program is good and only one bit was off. That means that either the computer would be reporting an engine problem that does not exist, with an error code that does. Or there would be a bad error code that would not be reported because it would have to be triggered by a problem with the vehicle.
Moreover, I would be real suppressed to learn that the flash does not have a checksum at a minimum. If the checksum matched and the flash was bad. That would mean at a minimum there are 2 issues with the flash (if it uses a check bit). I am going to assume it can detect more than two errors
Just an FYI

* I suspect they know the error code, and it is a sanity check error. Hence their assurance that it is drivable.

Mazda halted the use of one flash a month or so ago. within 2 weeks of that they released an updated file that had been de-bugged. so what they told you was a half-truth. if they gave you the buggy file then they are incompetent as they should have down loaded the corrected file by now. did they tell you the "false code" it was showing?

Thanks for the explanation.
I am guessing getting the FFD from them over the phone is going to be impractical then. When I am out there next, I will see if I can get a copy.
I am calling on the error code now.

P0126 Insufficient coolant temperature for stable operation ON 2
Thermostat ´ (See DTC P0126, P0128 )
Interesting, that does not seem to be an invalid code. I purposely did not talk to the service rep this time, and got the first guy I talked to in the service dept to pull up the codes it is reporting.
It sounds like they are full of $#@%. Great. Why would they be lying about something like that?

Same issue as you're describing.
