so i'm sure there are threads about this, but I can't find them. So if someone knows where they are could you please telll me.

BUT I got a replacement engine for my 05 8 a few weeks ago, I drove it back to school noticed the heat wasn't working. So went to take it the dealer and it started acting up again. After having it towed back in and having tests ran on it they are now saying that this replacement is having the same issues as my orginial so they are looking into putting another one in. Has anyone had this problem??

I'm not very happy with my 8, but mainly it's due to the dealer b/c I've gotten horrible service. So I just want to know if this is common....

Thanks!

I dont fully understand what you're saying. They replaced your engine because your heater didn't work? Why would you have the car towed due to the heater not working? Any chance of you explaining what happened in greater detail?

The replacement engine was not a new one. It was a refurbished engine. These are not being refurbished by Mazda. It has been farmed out to a couple of other companies. Apparently they made a mistake during the rebuild.
I purchased my car June 04. I had constant problems until finally in Aug 05 the engine was replaced. I haven't had any problems since.

Does Mazda want to **** people off?

yes, that is their intent. has it worked yet?

merdy05

yes it has worked!
well what happened was a month ago i had problems and they took it in and replaced the engine. i got it back and a week ago i was driving to school and noticed the heat wasn't working. so when i went to take it in the next morning it kept stalling. so then i had to have it towed in.
now they are saying that my 2nd rebuilt engine is doing the same thing as my orginal. i knew they were rebuilt, but i thought that mazda would of attempted to fix the problem instead of just putting another one in.

Mazda will just keep replacing engines until your warrenty runs out, then who foots the bill?

There is no fix for this engine issue and mazda has resolved to take the bite now until it's no longer thier problem, which is when your 60K warrenty runs out....

rotten42

That's my issue. I've already had mine replaced twice. I must say my dealer has been quite good to me. But after the warranty is out?...I don't want to take the chance. When my lease is up, the car is gone. It's too bab because I really like the car and I can't think what I would get to replace it.


maybe a crossfire?

merdy05

they extended my warranty to 6 years 100,000 miles b/c of all of this.
i do like the car a lot and i don't want to get rid of it, but this is insane. i never dreamed of all of this when i got the car.

if your dealer has given you shitty service, there's a strong chance that there mechanics blow big goats.

find a dealer with a good reputation and start there. It is always possible that you have a lemon. All car companies have them. Even "Toyota."

I put 97,000 miles on my 8 in 3.5 years. Never had a single issue with it and I drove the **** out of that car.

I think many of the engine replacement issues are misdiagnosed. The factory ecu in this car is in so much control and in such a strict way that if any one little thing changes, it freaks out and messes with other things. Then combine this with tech people who don't know anything about cars other than the fact that they have wheels and there are codes for issues and you really have some issues. Anymore it just seems like if there is a code that they can't get to go away, it automatically means that you need a new engine. I remember on the RX-7's when you had a check engine light that was persistent you just took the light bulb out. The engine would run just fine. They need to learn how to fix things. It seems to me that if the same issue has happened twice, maybe it's not an engine issue. Let's put two and two together here. When I work on something and I fix a part that I think is bad and then it does the same thing again, I really need to question if I actually fixed the right part. Maybe the part I worked on was bad but there was something else causing it to go bad that I missed. I think in may cases the same thing is happening with these cars. Techs don't know how things work the way they do anymore. They are too reliant on computers to tell them what to do. I think the worst thing going for Mazda right now is their dealer network and the goons that work for them. The next bad thing is the amount of completely unneccesary monitoring and control that the ecu has. Cars used to run without them just fine. They are only needed for so many tasks before it just goes overboard.

Jesus...you've done like 28k a year. You're a ****** trooper sir.

Make sure you take a nice picture of your odometer when you hit that golden 100k mark...which will obviously be in March.

By the way it'd be great if you devoted a thread to your car and posted updates about how it's doing every couple months once you reach 100k, considering that you are a good 2 and a half years ahead of everyone else. Think you can make it to 2010, elder?

Hmm... Heater not working... Then the engine goes out?

Sounds like SOMEONE forgot to put coolant in the engine ...

Yup. That would cause overheating (that the temp gauge would likely NOT see, since it would be in an empty cavity, not in fluid), and would explain lack of heat. Overheat a rotary, and really bad things happen in a short period of time.

Just curious - Did you/they check to see if there was coolant?

tmak26b

I have a feeling it is related to bad mechanics

devildog1679

FYI Check your states lemon laws.

merdy05

ya i put coolant in the car, checked it a lot too b/c i thought that was the problem. they said when the put my 1st replacement something on the heating block went out and it's very time consuming so they were starting on that today and getting my new engine in today or tomorrow. they've had my car since last thursday!

i'm looking into the lemon laws now. i can't handle this.

they are a horrible dealership, they say they have the top mechanics, but i'm doubting that.

rotarygod

The heater core is a very simple thing. It works or it doesn't as it's nothing mroe than a heat exchanger. Think small radiator. The only thing the engine needs to do is to flow water to it. You can remove the heater altogether. The engine doesn't care. I don't see how that could affect engine life.

^Handling will go to **** if you do that

AdRoCK3217

THIS is the reply I've been looking for! I see all these people talking about very slight issues such as this, and then the Mazda dealer goes and replaces the perfectly good engine!


People - there is NO DESIGN FLAW with the Renesis! There is a design flaw with the mechanic's head who diagnosed the problem!



Edit:

About the EMS issue you are talking about..

Seriously. The EMS needs to do very simple tasks - look at how the engine is running, what RPM, exhaust heat, AFR, etc..and inject x amount of fuel, at x amount of timing. That's it!

The EMS shouldn't be looking at things like head lights, taillights, the current G's being placed on such car, all of that should be handled in different ECU's..

Mazda needs to take a step back, and simplify the process..they will end up with a much better result!

I purchase a new 2006 RX-8 in December and had issues where the car would shake in sixth gear (Auto Trans) going about 53 mph up a slight incline while giving the car a little gas. The reprogrammed the computer first for the Trans Module, but that didn't work. They took the car back into the shop and ran tests and Mazda said replace the engine due to compression issues. Have not gotten my car back yet.

rodrigo67

Rotton, I remember you saying that...I was in the same boat. I loved the car but don't trust it. My lease was up and the buyout was way over what the car was worth, so I gave it back last week. I bought a beater (an 07 mazda3 hatch) until I find something else I like. I looking at the commadore when pontiac decides to bring it over and would definitely get another 8 if they throw 2.3 turbo into it...

AdRoCK3217

That would be the new Mazdaspeed Miata, which will have a (2.x liter) turbo motor. It will not be an 8, as it would not be "RX" as the prefix. Think.

The fact that you are looking to buy the new Commodore shows that you obviously didn't appreciate the RX8 for what it is.

rodrigo67

Nope, no more RX's in my future, but I would love an MX8.

I appreciated what the 8 is and what it can do, but I also recognize it's flaws. I bought the 8 because of it's handling, looks, and rear seats with 4 doors, but I could care less if it had a rotary or not.

In my opinion, the engine is the weakest part of this car. I don't care if it revs to 9K, it is the slowest car in it's class and got the worst gas milage. When corvetts are getting better milage and small 4 cyl. are pumping out more hp, mazda should rethink it's engine options.

The new commadore has 4 doors, RWD, comes with 300+ hp, and is 50/50 weight balance, shows I did appreciate the 8 for what it was, I just also took into consideration what it wasn't...

Let the flaming begin...rotary blasphemy...

I started with the computer. then the open recall came out. they replaced the motor, and now my car runs perfectly. no knock since the replacement.
