Mazda6 Maintenance and Repair

    I don't know if it's common. You should have it checked out. Bearings are not that expensive to replace.
  • Yeah, I've got 6 years of warranty on the thing, so I'll bring it. I just hate to keep it at the dealer and drive some sentra. I love my Mazda. :-)
    Thanks for the info.
  • This is a WARNING to all of you who are thinking of buying a Mazda at Polar Chev/Mazda, in White Bear Lake, Mn.
    My wife and I have had nothing but problems with our 2004 Mazda 6 (loaded V6). It only has 11,600 miles on it and it is about to go out of warranty (4 yrs.) this July '08. Our biggest gripe, and there's many with this car, is the rear engine seal. It started to leak 6 months after we got it. They replaced it and soon after it started to leak again. Polar Mazda kept putting us off by saying, "we'll keep an eye on it and if it gets worse, bring it in before the warranty goes off." That's what we did and sure enough, like I expected, they won't replace the rear seal. Their excuse is, they're afraid Mazda won't cover the repair. Polar screwed up by not doing the repair right and it started leaking again. They are now saying the warranty doesn't cover it because it isn't dripping. The whole area is wet and it's only a matter of time b4 it starts dripping. It wasn't dripping the 1st. time they replaced it. I think they're also afraid of the lemon law. When I mentioned it to them, they became real defensive. I'm not through with them yet, I'm telling everybody I know about this dealership. They're not selling many cars now, so I think Mazda is cutting corners. I know I won't buy another car there. I bought a '03 Tribute there also, which has had many warranty problems. The Tribute is out of warranty and now the transfer case is leaking with only 43,000 miles on it. They both have the Ford V6 engine which was in the Taurus. I like the engine, I just don't like Ford's cheap gaskets. We gave our 1998 Honda Accord to our daughter when we bought the Mazda 6. I change her oil and the engine is still dry, no leaks anywhere with close to 90,000 miles on it. I could go on about the problems we've had with our two Mazda's, I don't have the time or room to tell them all. Oh yes, I have to tell you all about the 1st. "FREE" oil change Polar did. I always do my own oil changes, but as long as they gave the 1st. one free, I let them do it. When I got the car home it was dripping oil on my garage floor. I had to jack the car up and tighten the oil filter. They couldn't even do that right!

    I'm sorry you've had such crappy service.

    I guess that's the difference between a great service dealer, and a poor one. I also have an 04' loaded 6s, and Delray Mazda in Florida has been a fantastic service center for me, this past 3 years. They've taken care of every fix, whether medium or small, in a timely fashion, and fixed correctly every time.
  • i have a used 2003 mazda6. it was running great for the first month (i changes the oil then). but after three weeks the engine was making a knocking/rattling noise. i checked to see what it was and the oil was low. after changing the oil again the problem seemed to just get worse and now i have no car. i still dont know what is wrong but everyone is guessing the oxygen sensor is bad or the engine is going to die soon. any ideas on what the heck is wrong with my car?

    I'd try another dealer and also contact Mazda. With only 11,600 miles your problem should be taken care of by Mazda, even if it were a little beyond the 4 years, IMO.

    How low was the oil when you checked it? Did you top off the oil?
  • chikoochikoo Posts: 3,008
    Just get a new PCV valve, ASAP.. a stuck PCV valve will suck up oil and burn it....
  • it was pretty low but after that i didnt drive it the next day i changed the oil an put about 4.5 to 5 quarts in it a new pcv valve does sound like a good idea

    Since purchasing my Mazda6 Sportwagon in March of 2006, I have had a very loud, annoying rattle when driver-side window is lowered 1". Dealer has tightened and adjusted loose regulator bolts, replaced window regulator, glass-run channel and applied weatherstripping, all to no avail. Now the dealer tells me this rattle is normal condition of vehicle. Has anyone experienced anything similar and what was your solution?
  • chikoochikoo Posts: 3,008
    he has done nothing, but charged MAzda for warranty repair.

    Change the dealer or call Mazda HQ.
  • any idea where i can get good parts???

    Looking for pc valve on 3.0 mazda 6. Is it necessary to remove engine shroud? TNX
  • MrShift@EdmundsMrShift@Edmunds Posts: 43,688
    The book doesn't say anything about removing the shroud, It's at the end of a long hose coming off the manifold but the diagram isn't very good. I can't quite make sense of it.

    They do say that when you remove the PCV valve you'll probably break the locking tab and won't be able to re-install it, so it might be best to check it in place.
  • chikoochikoo Posts: 3,008
    for sake of better clarity and avoiding scratching your hands, you will need to:
    1. take of the shroud
    2. take off the intake manifold.

    arghh! They aren't making things easy these days are they?
  • chikoochikoo Posts: 3,008
    good thing is this is actually covered under extended warranty so I had the dealership also change the spark-plugs while they had everything open back there.

    Did you ever find an answer? I'm having the same problem and cannot find an answer anywhere. I have several leads, but nothing concrete. So far, the most promising appears to be the need to replace a PCV valve. Not sure what this is or why it would give the code. Second possibility is a O2 sensor. Again, not sure why.

    I have a corresponding noise in my car. At times, it almost sound like a diesel engine. It kinda rattles a bit. I've read a bad PCV valve may cause the engine to burn oil. Maybe I'm low on oil and that's causing the noise.

    Using a diagnostic code reader, it gives me two codes, both of which are P0340. The second one also shows what looks like a "pd". So it reads "P0340 pd". I can scroll down in the menu and several other items are indicated, but they are not codes. It says things like, "O2 SNSR", "Engr", and various others. Can any body help?

    07 4 cylindercalls for 5-20. Will running 0-20 Synthetic cause any warranty issues. I don't see how it could void the warranty?
