Mazda6 Maintenance and Repair

    When my car was brand new it had a humming noise that I traced to the fuel tank. It took several trips to the dealership before they heard my noise and would fix the problem. They had to replace the fuel tank ...

    Was the noise problem solved?
    Sounds like your fuel pump was problematic. Did they replace it?

    p.s. the check engine light comes on when one does not sufficiently tighten the gas cap
  • I have a 2004 Mazda 6 Hatchback with 32,000 miles on it. I noticed early that all the seats started to show early signs of wear such as pilling. But now the front passenger seat, mostly on the back portion, is almost worn to the foam. I have not taken this to the dealer yet. Has anyone had success at the dealer and what have they done? Thanks!
  • At 15,000 miles, my Mazda 6 had a humming noise at times but never stalled. The dealer replaced the fuel pump and the noise stopped. But the fuel gauge has never been the same. It doesn't go to full and when on empty still has 5 gallons left.

    There is no sensor to adjust, there is a recall for the problem you are experiencing. The fan control module is bad and needs to be replaced. There are owners who have had their modules replaced twice already, including myself. There are other Mazda6 forums where you can find that information.

    My 2004 Mazda 6 wagon has made this noise since the day I picked it up: the passenger doors seem to jiggle slightly when going over bumps, creating a "chuffing" sound right in my ear. Dealer service has replaced the "striker plate" to no avail. Noise goes away if I push against the upper back corner of door. I'm thinking it needs more bracing, but I haven't seen any other such complaints in any forum. Advice?

    There are service bulletins out about the check engine light problem. One is to replace the throttle body assembly with a newer version. I had that done with 1200 miles on my '05 - might be the same problem with yours (?). Good luck

    Only issue so far is a slight rumbling sound from the rear passenger tire area when going over a rough road. No problem over a smooth road. Any ideas? Thanks

    Just bought a slightly used 6i.
    One of the fobs for the keyless entry doesn't work. The local dealer said it would cost 45 for a new fob and about 50 for programming.
    I think I should be able to do better than that. Is there any aftermarket fobs that will work?
    I changed the battery.

    Ebay, my friend!

    Just make sure you get the fob for your particular car. The fob for the sedan is different compared to the hatch/wagon.

    Once you get it, check out page 91 (I think) of this thread on how to program it.

    Good luck...

    Thanks for the idea..didn't even think of it. Have 2 NEW ones on the way for 35 bucks W/programming instructions. Can't beat that!
    Only had the car for a couple days but I really like it.

    Bought my '04 Steel Gray 6S manual sedan new...

    One year and 16K miles later...

    Still grinning from ear to ear...

    Bought a new 6 in october of 2004. I noticed the horrible smell immediately, my husband said it was a under coating and would burn off. 10 months and 9500 miles later it still smells. I was told to change gas. That didn't work. Now my head lights work when they want to. This is the second time in the shop since June. If they can't make the problem re occur they won't do anything. I am getting mad. Anyone else out there with these issues?
  • slennonslennon Posts: 2
    I had a similar problem. It seemed as if it slipped out of gear if I let off the gas and then didn't completely stop. The dealer re programmed my transmission. It helped, but it still does it sometimes, not as violent though.

    Sounds like a problem with the catalytic converter. I've never had this problem myself, but from what I've heard and seen from other 6 owners, you could have a bad cat.

    Make sure the dealer checks the electrical connections thoroughly, and there's no short circuit anywhere in the fuse panels or the switch.

    Always remember that you can bring the car to a different dealer to have it worked on. Unfortunately, some car dealers aren't the best in service/repair, and some dealers will often see things that other don't. Happens with all makes, not just Mazda...

    Good luck. Let us know how things turn out. :)

    Which AT do you have? Tech services is working on complaints about the 6 speed autos (I have one) with jerking and overloading in the 1500-2000 RPM range, all gears.
  • i have a 2004 and the seats are a beige/tan color supposingly with this scotchgard type sealant for spills, hah, if anything it is the worse sealant i have ever seen. spills do not just wipe off and i tried just the damp cloth which are the instructions, the stains just get bigger, and mazda doesnt sell a cleaning agent to take care of this. i now have beige front and back seats that look like 10 yrs old. it is just ridiculous. and YES I HAVE FUZZIES THAT ARE EVERYWHERE. i have to constantly trim the frays and i figure by 2007 i wont have any cloth left.

    I thought the 5spd ATX was bad. Now i see similar problems trickling down to the supposeibly indestructible 6 spds.
  • Recieved the key fobs from the dude on Ebay on friday and within 15 minutes ahd three fobs (2 new 1 old) programmed.
    Thanks for the idea.
  • I have one with 7 k on it and I noticed it doing that as well - but not to the point where it is to the foam, yet, over the long term, I am worried about the durability.
  • My Information LCD screen on my m6 got all glitchy over the last couple weeks. Like when i change my volume there is a blank in the middle of all the numbers. Also when it is showing how far i am into a song on a cd there zeros look like a backwards C. Did this happen to anyone else and will the dealer fix this under warranty?
  • Did this happen to anyone else and will the dealer fix this under warranty?

    Hasn't happened to me, but I've heard about it.

    Chances are it's a faulty LCD board. They should be under warranty, although the dealer may have to order one. It MIGHT be a loose connection between the radio and the LCD, but the symptoms shy me away from that conclusion...
  • I have taken my 04 Mazda6S to the Dealer for the same problem (5 times); Brake moaning at low speeding, when approaching stop lights or parking spaces. A TSB was issued for this problem, but it continued to come back after each fix. I was then told that's how it is. Well, I had my car serviced in July 05 (oil change), and I mentioned that my brake pedal squeaks when I press on it. They checked it, and fixed it. I noticed the difference, but within days it was back again. Well, yesterday I took it back again because the brake pedal just did not feel right. The Service Department called and said that my Front Brake Pads were below 20% and needed to be replaced ($219.00 plus tax). I raised H ! L L, I have never replaced my Front brake so soon pads on a vehicle. I requested Mazda's number from the Service Department, because I was not a happy camper. To make a long story short, I explained my situation to the Mazda Rep; she called the dealer and told them that they will pay for the Front Brake Pads to be replaced. :D

    SO........... If you hear your brakes moaning at low speed, take it to your dealer. Make sure you have a paper trail so that if this situation should arise, you will be covered. :)

    I have had a Mazda6 i for a few months now, I have 4,000 miles on it, and I have no problems what so ever to report. I have been reading some complaints about CEL's and a stinky smell. I had the smell for about a week, then it went away. I also work at Mazda dealership. If anyone has any quesitons, I have to sources to get you good answers. Our service dept. is one of the best around. :D
  • Mazda 6 2005 clinging noise occurs at 60 + mph. Can't locate issue and dealer can't locate noise because they do not go on highway when they test drive it. Noise does not occur at lower speeds and there doesn't seem to be any negative impact to the running of the car.
  • I own a 2003 Mazda6-i with 34000 miles on it. Last saturday the battery warning light came on. Took it to the dealer. They said it had a bad alternator. How does an alternator go bad at 34k miles? There was no indication that it was going bad. The car acted normally up until then, and even when the light came on. Has anyone else here developed a bad alternator with your cars? Is there some svc. bulletin I missed?

    I've had 3 repairs (all different) in my first 6k miles. First was a fuel sensor, can't remember the second off-hand, third was a bad throttle body. Anyone else having so many issues in such a short time? I'm thinking of going back to the dealer and demanding a free extended warranty. I can't stand being without a car all the time.

    2003 Mazda6-i with 34000 miles ... had a bad alternator. How does an alternator go bad at 34k miles?

    So did the dealer replace the alternator?

    got mazda 6 . have a tinny sound when pressing down on accellerator. took it into dealers they have heard noise but are unable to locate it. could this noise be the thrust baring as my husband has suggested. i only have another 500 miles left on warranty. don't want somthing costly going wrong...
  • mazda6smazda6s Posts: 1,901
    ycox - You should keep your service records. To be covered by warranty the problem must be shown to exist before the warranty expired.
  • autonomousautonomous Posts: 1,769
    "thrust baring" What's that?
    tinny sound Do you mean tiny sound or sounds like tin?
