Just got my Remanufactured Engine by secondcity

Went in for an oil change and any service related to 25,000+ miles and also asked Mazda to perform any recalls related to my 05 rx8 (Grand Touring manual). My only complaints to the tech at that time were minor rattles coming from heat shield and the dashboard instrument panel. They asked me to leave the car with them for the weekend. I got a call a day and a half later saying that my engine did not pass the series of tests performed on the engine which is related to the recall. I was told I would be issued a re-manufactured engine. I never experienced any problems with the old one. Not one. I beat the hell out of that old engine and it ran great. I spent more time between 5-8500 rpms than I did at 3000! (Just kidding)
 
 I was hoping for a brand spanking new one, but oh well.
 
I was caught completely off guard because I live in chicago and recent posts said the engine problems were related to most cars in warm/hot weather climates. I was also surprised because the tech test drove it with the old engine and said the performance of the old engine was not at its full capabilities.
I got it back about a week and a half later (today), and I have to say it runs velvety smooth. I don't notice any increased performance, but the car feels smoother during acceleration and quieter during revs. It feels like it did when I first bought it. Plus, they took apart my instrument panel and tightened four loose screws that were causing the rattles. They even re-secured the heat shield underneath to stop the underbody rattle. No more rattles. My total bill was 85.00 for minor parts, replacing the cabin filter and rotating of tires. Not too bad considering the only money I have ever put into this car were the Blizzak winter tires and oil changes. I even got upgraded brake pads to stop the squeaking.
 
I know there are some people ticked off about the engine problems or service and its understandable, but I am not at all miffed about the engine replacement. The service was great and my little toy runs like its new. I recommend that everybody get the recalls dealt with, regardless of what type of climate you live in. My tech said he has had to replace 7 RX8 engines over the last 6 months.

RX8 ENGINE PROBLEM by t_rev

I have an 04 rx8 A/t w/ 52k, and I live in Central Arizona. We have probaly 90+ days over one hundred degrees. My car was making a funny vibrating grinding noise when i would get up in the higher RPMs, and also under a load like going up a hill. The RPMS would also fluctuate. I took it in 3 times under the 50k warranty for it and they could not duplicate it. 3 days ago, my wife was driving it in phoenix and the cars RPMS fluctuated like crazy and it died. She got it started again and pulled into a shopping center. We had it towed in and left it at Earhardt Mazda. I am now out of warranty so when I spoke with the service advisor, he said that It looks like I am gonna need a new engine, and he is in communication with Mazda to see if they will cover it. I bought it from them only 3 months ago, and did my job by bringing it in to document this problem and they might not cover it? Any suggestions..

The warranty was extended to 5 years/ 60k for the powertrain on the RX-8. Unless your car was originally titled more than 5 years ago, mazda will pay for it. Call Mazda if the dealer says they won't cover it.

I have been speaking With mazda about this problem for over 3 weeks. They still have my car and cannot figure out what is wrong with it. Now they are saying it is the Catalytic converter. It is on Nationwide Backorder and they can't seem to scare one up. When the service writer spoke with me about it the first time, he said the tech found water in the combustion chamber. I know that condensation can build up in the exhaust system, but there should never be "water" in the combustion chamber unless there is a crack between the water passages and the cylinder wall or water coming through the intake because of a bad gasket, what does the catalytic converter have to do with this. I work fro a gm dealer in parts, so i know alot about domestic stuff, but the rotarys are kinda there own thing. I miss my car man, this Chevy Aveo rental isn't cutting it, lol.

I'd go sign up for RX8club.com. Lots of technical advice over there. One guy I know locally got a new engine when they found coolant in the combustion chamber.

Guys,
 
I bought my car in 6 months ago, after warranty, because the engine was driving sluggish and the engine light was on. Mazda service put new coils on and when i got in my car the check engine light instantly came on. Great repair job! I immediately took it back to Mazda service and they said they made a mistake and they replaced the spark plugs. Couple weeks later the check engine light came back on, but i wasnt able to return for a couple months later until 3 weeks ago. I brought it in and they replaced my cat. convertor which was under warranty b/c i now have 72k miles. Got lucky. 2 days later my check engine light came back on and I was livid. I took it in and they said they knew what the problem was. They replaced something and i told them to drive it for 2 days and find the root of the problem and stop reading what the computer says. They just called me saying the intake valve(i think) needs to be replaced. The part is 1600 dollars and they have to pull the whole engine out in order to do this make the total cost 3600. What can i do about this?

Are The Old Problems With The RX-8 Solved? by boswell1

i've read alot on various websites regarding the RX-8, and was wanting to get some info regarding all of the recurring problems this vehicle seems to have. most of the problems seemed to be with the 2004/2005 model. Consumer Reports even indicated these years had their share of problems.
 
1) Is the flooding problem a thing of the past with the 2008 model?
2) Is the oil consumption a thing of the past with the 2008 model?
3) Do you have to let it warm up all the time before you drive it ?
4) Is it a reliable car? one that wont need to be towed to the dealer all the time?
 
i am looking for a reliable car, thats the #1 thing for me. and i would like to have a sporty type car too. i want one i can just jump in and go, not one that absolutely has to be treated with kid gloves or else it wont run and has to go to the dealer.
 
and speaking of dealers, i had one tell me three days ago the RX-8 is "Finicky" and that makes me wonder about it.
 
can anyone shed any light?
Mike

if reliability is of a big concern, I wouldn't buy the RX8. I'll probably get flamed for saying so, but there are a lot of quirks. I just sold my 2006. Although to be fair, some guys never had a problem for 100K+ with 2004's. I can't comment on anything other than my old 06.
