Mazda6 Engine Problems

    The believed the dirt bag dealer Dworkin Chevy Mazda're a race car driver...own a sporty ...and yet you claim you are smarter then the manufacturer who built it....yeah, I can see why they didn't want to cover it. So, since the mfgr proved you abused it, that makes the dealer "dirt bag's" Yeah, ok, that makes total sense.

    If abuse was proved, you lose. Apparently that's what happened. If you can prove you did not abuse it, which since you are sooo smart, you should have done.
  • At six months old was rusting at back wheel arches, back wings were cut off and replaced under warranty. Then water started coming in through the repair. Into dealer three times before finally fixed . Now i have a rattling noise from the engine 64000 on the clock, and now the battery seems to have went too, it is also going through lots of oil but no sign of a leak,time for a trade in I think to something more reliable.

    I don't know about the overseas Mazda6, but here in the states that seems to be a well known problem associated with the PCV valve malfunctioning. I know it's probably a waste of time, but you can see if the place you bought it from will do anything for you.
  • my girlfriend has 2003 mazda 6 with the i4 auto trans and it ran good at first then the engine start acting up the rpm'ss would go up and down you had to leave the ac on so it would'nt die at a stop light we took to the dealer for the diagnostic and the said the problem was a vacume leak under the intake and wanted like almost $800 to fix most for the labor. so we took it some where else. And it now a year later same thing is happing again took it autozone to have the engine code looked at this mat sound weird but there are four codes in the computer and some are reapeate codes. p2009 three times p0302 two times other are p0410 and p2004 those were the codes autozone was showing. the engine will start backing fireing then start shaking like its runnig out of gas. we had the o2 sensor was replace before. Any sugestions? please. this car is junk and it sounds like they have been having may problems
    Thanks :confuse:

    so we took it some where else

    problem #1...if you had the Mazda dealer fix it, they would have used the corrected part. A local mechanic would have used a replacement part....

    And it now a year later same thing is happing again took it autozone

    Autozone does not have the correct engine codes all the time....

    What ever car you buy, or own, always bring it to the manufacturers dealer to resolve issues, especially because of the complex nature of the computer systems....
  • I've started having this same problem with the burning odor when using the HVAC on my 2006 Mazda6 4 cylinder. Greg, did you ever find out what caused the problem? Has anyone else had this same experience?

    Have you changed the cabin air filter? They can get plenty smelly over time.

    UPDATE: I wrote the original item here. I'm very pleased to report my Mazda 6 is running super with the replacement engine $2500.00. Mazda was usless in helping me with my "under warranty" problem. They stuck with their awful position that YOU CAN NOT DO YOUR OWN OIL CHANGES! They are "DUNG" I have had 7 Mazdas and no more. I just bought a new Subaru. More rewarding is Dworkin Chevrolet Mazda has closed. I only hope I helped these bastards die. I still want to hear the service manager Bob Kenworthy has been eviscerated, castrated, raped and killed.

    Help, I purchased a M6, 2006 with a remote keyless entry and I have a problem that occurs intermittently. Whenever it is starting to rain or we have very high humidity my horn will blow 3-10 times in very short spurts and I have no control over this. Most of the time it is when I press the brake but sometimes it just goes off. On one particular occasion it kept up a steady series of blows for 20 miles. If I replace the fuse under the hood it sometimes stops immediately only to return a few months later. I have no Idea when it will reoccur. Dealership is baffled, said everything checked out. Thought it was related to the Keyless R Entry/security system but the dealership says no. Please any ideas would be greatly appreciated, this could be very dangerous, people think I'm blowing at them and they don't alway take kindly.

    I have the 2009 mazda6 2.5 I4. I am noticing a tapping noise when accelerating from a stop at low rpm, as the car shifts, the noise is gone, so only appears at initial acceleration. It does not happen when idling. And I only hear it in the evening probably because of much less outside road noise at night compare to driving during the day.
    I tried reproducing when at idle, I can hear it if I rev up slightly to 1000 rpm. if I increase the rpm, the tapping sound is gone. Is this normal of this engine, or should I be worried and take it in for service? I did notice on my oil change receipt from the dealer that they are using bulk 5w30 oil. The manual recommends 5w20 oil. Could the
    thicker 5w30 oil be causing this issue?
  • Mazda has recently denied any engine repairs on my 2006 Mazda 6 with 34,000 miles on it which is 16,000 under their warranty. They state that because one of the oil changes in service history was not done at dealer my warranty is void.Was told to provide the receipts from that oil change yesterday and told today dont bother because we have voided warranty. How can they do this?? They dont know what is wrong with it to begin with other than seals are leaking oil and a problem with cylinder 3??? But refuse to investigate any further. Isn't there a Mazda Corporate complaint system or something out there???

    Mazda has clearly turned to s**t. I loved all 7 of my Mazdas but I just bought a 2009 Subaru. I tried all ways to get Mazda to fix my 2007 Mazda 6 and they refused. They have a problem with these engines and are hoping it goes away one by one. How can you tell what's wrong without taking my Mazda appart. They refused. Complaint department sucks. I had done my own oil cahnges and they said they was the problem and refused service. Not buying Mazdas is our only recource. Good bye Mazda, what a shame.

    Not buying Mazdas is our only recource.

    A simpler solution is to just get the oil changes done at a dealer, at least during the warranty. I am not saying that what Mazda has done is right or fair, but getting the oil changes at the dealer (and on time, of course) would avoid all these sort of hassles. The cost of doing this is minimal...maybe $10-20 extra per oil change over doing it yourself.

    I don't agree with the Mazda schedule that has me changing oil every 4 months (which is generally about 3000 miles), but during the warranty period I am following this, just to avoid any potential hassles. After the warranty is over, I'll go to a 6 mo. schedule or go to synthetic and change once per year.

    I would agree if Mazda's Owners Manuals warned that doing your own oil changes voids the warranty. They lied over and over to me. Having my oil changed at the dealership is a day long 50 mile ordeal. Mazda USA has turned to S**T!!!!!
  • jeffyscottjeffyscott Posts: 3,855
    The manual does say: "The owner should retain evidence that proper maintenance has been performed as prescribed."

    Not sure what they consider to be adequate evidence, though.

    You said: I had done my own oil cahnges and they said they was the problem and refused service.

    Did they say this because they felt you did not have the evidence to show that the oil changes were done or because they thought the oil changes had not been performed correctly?

    What exactly was the problem that you had with the engine, anyway?

    Good for you!!! I had multiple issues with my 2004 Mazda 6 :lemon: . I had to complain to Mazda Corporation and I won everytime. But, July 2007 I had enough so I traded my 2004 Mazda 6 for a brand new 2007 Lexus IS 250 fully loaded, which I LOVE!!! No more Mazda's for me!! :lemon:

    I'm a mechanic with a lift here at my home. I have all the necessary equipment to do anything regarding auto repair. Mazda said they do not recognize home oil changes. I have receipts showing the oil and filters. I was required to have performed 2 oil changes and I had done 3. The engine thru a rod bearing. I replaced the engine myself.
  • jeffyscottjeffyscott Posts: 3,855
    Thanks for the details. Was it the I4 or V6, btw and how many miles were on it when the engine blew? Just curious.

    i have a 2006 mazda 6s 3 litre v6 that blew a rod at 59 000 miles this is totally ridiculous and of course my warranties up and ofcourse they cant do anything for me at all. now they want these services reciepts for the car and i bought it used in 2008 so anything from 06 till feb 08 i dont have and ofcourse since i like to take care of my own cars they wont honor the fact that i changed the oil myself a few times, the odd part in all of this was my last oil change and service was done at a mazda dealer 1 month prior to this of and they readjusted the cam caps which is a bs do nothing operation that cost me over 300 bucks. so i finally take it to the dealer and a month later the motor blows hmm thats odd to me the car never had one single problem before entering the dealerships except a bent rim that cost me 250 to replace. so now im stuck with this car that needs a motor and ill be dammed if im going to pay 8000 out of pocket cause mazda dosent back their inadequate products and secondley no amount of oil changes would prevent this from happening thats bs also and further more if they want to play that game my oil was changed by them a month before this happened by their mechanics. if anyone can help me get them to pay for this id highly appreciate it. i know this ill never own another mazda again their non driver friendly maintence requirements are ridiculous and the fact that they only honor work done by them is even more bogus.
