#86 of 101 Mazda RX8 engine failure by danboyle1

Oct 15, 2011 (9:27 am)

I have a 2008 RX8 with 33,000 miles on it. My car wouldn't start. I got it to the Mazda dealer, and they said there was a blockage in the catalytic converter that didn't allow all the exhaust to get out and damaged the engine. Now they are going to provide me with a re-manufactured engine with new parts. It's under warranty. My concern is how the new re-manufactured engine will work. I'm wondering whether I should do a straight trade of my RX8 for a Mazda 3 (since I have about $15,000 left on the loan). I wanted to get anyone's opinion on what I should do and if they've ever had an RX8 with a new, re-manufactured engine.

The re-manufactured engines are a crap shoot, some are good some are not. Personally I would not worry about it because of the extended warranty

You have a 100K warranty with the engine so if it does fail you are covered. If you want to change it out for other reasons, that is your call.
 
Good luck.

You better get them to replace that catalytic converter too or it won’t be long before the same thing happens again. You cat is covered by the emissions warranty 8years/80k miles.
 
However, you may research putting in a replacement pipe. Racing Beat offers 2. I bought mine a while ago and it’s never given me an issue... just a few extra horses

Their not lemons you just have to know how to treat the engine. You should have done some more research on it before dropping that kind of money into a car you know nothing about. It has a rotary engine which is a lot different then what most cars have and you have to treat it differently. I own a mazda rx-8 also and have absolutely no problems with it. Before turning off the engine you need to rev it up to roughly 3000 rpms for a few seconds and it will start up perfectly fine the next time. For future reference know what your getting before you buy and it'll save you a lot of time and money.

#92 of 101 Engine Problems by wslonecker

Jun 12, 2012 (6:43 pm)

We have had our RX-8 for about 6 years now and have just started experiencing problems. We have always kept up maintenance and what not. During hot weather we cannot run our A/C or the car will die. That was our first problem, now everytime we start slowing down the car will die, we have replaced the battery with a Optimus and now the car starts right back up however the engine light stays on. It's no surprise if the car dies 2-3 times on us whenever we make a 30 mile trip. I called our Mazda dealership and found out that our car still has the engine warranty and I was told it would be $200 to run diagnositics on the car and if it was engine problems then they would waive the $200 and fix whatever is messed up. I am really leaning towards it being the engine however I hate to take it up there and have them say it's something completely different. We have hooked our diagnostics machine up to the car a few times when the engine light would come on and it has always suggested replacing the engine to fix the problems so hopefully that little machine is right!!

#93 of 101 Replacement Engine - update a year later by strongtree

Jun 12, 2012 (8:09 pm)

Hi again RX-8 owners,
 
responding a year later to my original post regarding trying to get Mazda to replace our engine on the 2004 RX-8. I had spark problems and it wouldn't start. that cost me $750 to find out the engine was bad at the dealership, then $1000 to get the engine replaced. I will say that Mazda does realize they have issues with this year of engine and did replace it. They originally said I had to show that oil changes had been maintained for the first 40,000 miles but I had no way of doing that. After complaining to them they said they would replace it but I had to pay $1000.
 
so we replaced it, then the gas tank wouldn't fill correctly at the gas station. the gas pump wouldn't lock and stay on so you had to hold the handle on while filling it and it would click off avery few seconds. getting a full tank took 20 minutes minimum.
 
after that the engine light came back on and stayed on most of the time. i traded it in to a dealer at a $4,000 loss from what I paid which includes the cash I put into it.
 
i would not buy a rotary engine again and would warn others to seriously research them prior to buying one. Mazda did replace it because they realize they have issues but it's not worth the hassle and cash. i think mazda makes decent cars, just not this year and engine. so beware. that's my story. i read a few posts on here where others are having good luck with them, so good for them. i hope they continue to have good luck, all i can do is report my unfortunate luck and warn others to do their homework.

#95 of 101 check engine light high rpms by clrx8r3

Aug 31, 2012 (7:03 am)

Hello all,
 
I wanted to see if anyone experiences/ have experienced the same problem as I have. I have a 2009 rx8 r3 package.
 
Every time i get on the highway and i go about 70-80 at around 4000 rpm in 6th gear my check engine light goes on.
 
If i go faster or slower there is no light.
 
Is there anyone that can shed some light on this issue. Is it electrical or do I have a leak somewhere??
