I've talked to many people that have had their catalytic converter fail very early on, and as a direct result damaged the car (body,exhaust) as well as put drivers in danger. Is this a problem you think Mazda should address or should we not worry about it?

 

ive never had mine fail or heard of neone else's fail...

 

i assume you're joking about never hearing of anyone's failing. aside from that, flooding seems to increase the chances of a clogged cat and mazda has "kinda" addressed the issue.

however, i think it's a good idea to recall. i could always use a high flo cat

 

Would a high flo cat solve the problem?

 

Nope, I had a high flow cat fail on me after 20k miles.

how about a test pipe?

 

I've had 3 replaced on my car in less than 20K miles. Working on number 4.

 

your stock catalytic converter is warranted to operate up to 120,000 miles, if it fails you can get it replaced under warranty, why recall all the good ones that are working fine?

 

neone? anyone. Must be posting using text messaging. "else's" was good though. Sorry, just bored.

 

I looked in the NHTSA database and saw only ONE complaint about RX-8 catalytic converter failing. There aren't ANY ongoing investigations on the RX-8 either. Don't see a groundswell for a recall based on that.

 

If the cat is rated for 120,000 miles how come so many people's are failing below 20k miles??? Not to mention multiple times under 20k. I don't really care what it's rated for or how many people have reported it to NHTSA, some people don't care to report it cause it's covered under warranty, bottom line they are failing way too early. Maybe instead of replacing it multiple times they could design a better one that will last at least half of the time it's rated for.

 

Mine Failed (CEL on, same error) after like 8K miles. Now Im on 10K miles. but I dont really think I need to take it in yet. Well, Im lazy ok ?

but I think, it has something to do with the engine (flooding?) or the temparture. dont u guys think so ?

 

Well from the few posts I've read it seems that flooding contributes to the cat failures.
That may or may not be the general consensus here. I've never flooded or had any cat issues so I hardly read any of those threads.

 

I just had mine fail at 30K..CE light came on...acceleration problems, and RPM would shoot up and "hang". It was replaced last month. Now this weekend my CE light came back on..What a PIA................

 

I think Mazda should def do something, seems like no one is gonna get remotely close to the 120,000k mark that the cat is rated for.

 

If you discount increased greenhouse gas emissions leading to global warming and ultimately killing everyone, it's not a safety issue. Let them replace failed ones when they fail. As long as they cover them under warranty, I see no reason to issue a recall.

 

And if it does not not last 120K Mazda will replace it. What more do you want them to do?

FYI 57,000 miles on the same CAT.

 

I had the same thing happen around 3000 miles. After the dealer went through an O2 sensor, and talked to Mazda for a couple of days, they replaced the cat and it went zoom again. Almost to 10k now, with no more probs.

 

Mine failed at about 8000km.

 

Ok well if they keep going so quick something isn't right. They go way to soon. And I bet they're gonna do something about it if they need to replace them on so many cars as early as they have been.

 

Do you see the numbers people are giving here......?

 

we have TWENTY-TWO posts here, and not all of them are directly about a burnt out cat, what about the TENS OF THOUSANDS of WORKING catalytic converters that are on RX-8s throughout the country.... internet forums like this ALWAYS make things look worse than it is...

 

I have never seen a bad converter on a vehicle with no flood history.

If you have had a converter replaced and YOU have not flooded the vehicle, it was flooded before you owned it.

Cold starting this vehicle shows injector pulse width numbers ten times more than full throttle. Once the car is flooded all the fuel gets in the converter. Frankly a convertor is not designed to handle that type of heat from pooling gasoline vs airflow.

 

mines died 2 weeks after i got the car. reason for the check engine light, my car is like a sick child, you got to take him to the doctor every month
