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?
#22 of 115 Are The Old Problems With The RX-8 Solved?
Mar 25, 2008 (9:35 am)
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?

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.

1) Flooding: ANY rotary engine car, including 2008, will flood if not warmed up. It's the rotary design. Start it cold, move it 50 feet, turn it off immediately, and you've got a flooded engine potentially. You can try holding a 3000 RPM rev for ten seconds on a cold engine, then kill the ignition for a emergency cold engine shut down, but that's extra ware on the cold engine engine.
2) Oil consumption: Burns 1qt/1000 miles. It is suppose to. Otherwise the engine will be no good fairly fast, because not burning oil means there isn't enough oil getting to the apex seals. Keeping RPMs above 3000 when driving will insure good volumes of oil circulation.
3) Warming up: There's a high pitched fan noise that runs for 20 seconds or so, that's blowing exhaust gases out when the engine is cold. Let this stop at least. Then don't go popping 7000RPM when you first drive off until the water temp has reached mid level. Five minutes at most, then your good to drive like a maniac. Think to yourself, "the calm before the STORM, before letting the twins howl!"
4) If you don't screw up 1,2 and 3, your new RX8 will go for well over 200K miles. And then you can re-build your own rotors, simple as pie. Watch the video: http://www.rebuildingrotaryengines.com/videos/rx8-renesis-rotors

so, what happens if the engine does flood, and the car wont start?
1) have to have it towed to the Mazda dealer for them to do their thing to get it started?
2) let it sit and it will eventually start? 5 minutes? 5 hours? 5 days?

There is a flooded engine recovery procedure.
From the manual:
Holding accelerator down all the way + turning key for 10 seconds
Then crank for with/o accelerator for 10 more seconds
Repeated procedure twice.

I've never flooded my RX-8, but I did flood my RX-7 several times. Flooring the accelarator and cranking 10 seconds always worked, but there was a huge cloud of smoke after a flooding restart.

i've talked to other people that say the potential flooding problem and high oil consumption being the norm for a rotary engine is complete BS.
so, who do i believe? where does a guy go to get the absolute best info regarding the Mazda RX-8?
on the one hand, i'd hate to buy one and start having problems with it. there's nothing worse than having car trouble. but on the other hand, if all you need to do is not shut the engine off when its cold, and add a quart of oil every 1,000 miles or so, thats no big deal.
