    I have similar trouble with vibration.
    Mine was manufactured 11/05/04.
    Sorry 'bout that, got your specs.

    My Buzz is coming from the exact area!. Most Dealers will simply tell you they can't duplicate it, and wont pull the panel. I lucked out at a brand new dealer who had an immediate afternoon opening for servicing. Got to love that, instead of having to be there first thing in the morning. So now the noise, like wires scratching seems louder but occurs less frequently. :) And yes, there is always a good chance they will mess up things when they rip a panel open. Other than that, the Sonata is awesome. I thank this Dealer for at least doing the work that other dealers just blow you off, or charge you for. The bottom line, I'll can go back until I am satisfied, I am happy that the Dealer made this effort, and will do so again. Let us keep in mind, it's an American Hyundai with some of those same ol' Korean parts :D

    My car was manufactured 11/11/04. I am still having trouble. I believe im just getting the run around now. I am told the car is perfect, but yet service claims that they changed a few things. I'm not sure i believe that they even took the car out for a road test. I no longer have any trust for Hyundai.I am in N.J. any suggestions?

    Looks like there is a growing list of us with not only the same car vibration problem but the lack of resolution to the problem. Please continue to post on Edmunds. I am beginning to think we should all band together. I have not thought of exactly what yet but if we all get together maybe we can get the problem solved. What state do you live?

    In my experience, engine vibration problems are often gasoline related. Have you tried another gas station?

    I had a car for 11 years, and except for 5-6 tanks of bad gasoline, it ran silky smooth. The first time it started running rough, we thought it was something serious. By the 3rd episode, we finally caught on. The last couple of times my wife would say "I got some bad gas again!". It always cleared up when we ran the tank empty and got gas from a trusted station. YMMV, of course! :)

    I have a 2002 4 cyl. with 72,000 mi. For about the last 2000 mi., the CEL light has come on and the engine runs very rough at times. I have brought it in twice and was told the first time that the vapor recovery valve was broke probably because I topped off the gas tank too much. The second time I was told that the gas cap was loose. The CEL came on again, went off and is now back on. The dealer is sticking with the loose gas cap theory, but I know that is not true. When I say that the engine runs rough, what I am saying is that it suddenly feels like it is running on 2 cylinders. It chugs, misses, and has no power. This might last for 1 mile or 3 days. Then it is gone... only to return again. It happens at all speeds. Sometimes I cannot maintain 65 mph. because there is no power. Then for the next 200 mi. it runs just great. I believe that I have ruled out bad gas by purchasing from different reputable stations (after running the tank almost dry). Anyone else experience this?

    What is concidered bad gas? I have only used BP in my car.
    Please tell me what is bad gas.
  • carfaxcarfax Posts: 43
    Some gas stations don't keep their under ground tanks as clean as they should. The tanks get excess water and other crap in them which sometimes mixes with the gas as it goes in your tank and then your car doesn't run the way it is suppose to. Most brand name gas stations are pretty good, but some not so high volume stations have this problem.

    Gas is stored Underground in big metallic tanks... as they age they are prone to collect more dirt/rust and specially Water (mostly from condensation), which mixes with gaso;ine and then goes in your car!
    I always try to stay away from old gas stations... it is easy to tell which one is old and wich one is new/newer.
    The station brand is really not that important... very busy stations are usually better; because they refill their gasoline almost daily!

    Starting with the concern about old, leaky gas tanks 15 or so years ago, I thought replacement tanks were fiberglass or some other type of plastic material.
  • carfaxcarfax Posts: 43
    An other way you can get some bad gas is filling your car up when the tanker is filling the station tanks up. The pressure going in the tanks stirs up all the crap that has settled at the bottom of the tank and mixes with the fuel that is being pumped into your car. My father in-law owned a gas station years ago and said that this is the worse time to ever fill your tank is when the tanker truck is at a station. He tried to have his filled at the time of day when it was slow for business. To days fuel injection has a much smaller hole for the gas to go through then the ports in the carburetor days.
  • I bought mine from global in north plainfield stay away from those mafia sharks!!! Dont say i didnt warn anyone they prey on the unexperienced and i am experienced, they lie,and sell you defect left overs, if not possible flood cars..DO not go there I have been a fool twice in 3 years :lemon:
  • bobadbobad Posts: 1,587
    Water, trash, or even too much alcohol can make your engine miss. It's amazing how bad my engine ran on some gas, and how fast it recovered on a tank of clean gas. It was like night and day.

    But,,, that may not be your problem. However, it needs to be ruled out.

    I have 06 Sonata, it started to make a sound like a wind noise, but when I make a right turn it is more of a rubbing sound coming from what I think is the right rear area. Dont know if this is the right place to post. we did it. Anyone have this problem ,just turned 3000 miles ???

    Has anyone tried to change their own oil filter yet?
    I just came from the dealership and they give me a
    filter cartridge and 2 "O" rings. I haven't seen a
    cartridge oil change since my old John Deere tractor.
    Are there people in the 21 century?
  • bobadbobad Posts: 1,587
    Welcome to the 21'st century, where many of the better cars have cartridge filters. I think the manufacturers are going to cartridge filters because the bare element doesn't hold a big glop of oil like the spin-on filters... you know, more environmentally friendly.
  • I have done it several times. Large O ring seals the top cover and small O ring snaps on to the stem on the cover. The canister snaps on to the plastic stem and currently can only be purchased from a Hyundai Dealer. Only problem doing an oil change is removing the plastic engine cover. Hyundai should have designed a break away cover on top of the oil filter. Otherwise nice location for the filter assembly, easy to get at and replace. Hope this helps.

    "The canister snaps on to the plastic stem and currently can only be purchased from a Hyundai Dealer."

    Maybe not. Someone over on BITOG (an oil forum - yeah, there are oil nutz who periodically slip away from the "farm" and masquerade as normal people on BITOG) posted within the last week that Purolator now has a cartridge filter out for the new Hyundai Lambda V6 engine family. He said he got his - a "PureONE" premium design - for ~$5.00 at Pep Boys. If this is true (I haven't checked) Purolator's standard "Premium PLUS" line's version would probably come in around $3.50.
  • desertguydesertguy Posts: 730
    I just checked Pure Oil's website and it shows the filter is not available for the V6. It has been assigned a part number though so maybe soon.
  • bobadbobad Posts: 1,587

    People are buying the Pure filter. I guess Pure didn't update their web site.

    I get that a lot with my `03 Sonata. (50,000 miles) A quick drive through the service bay and it's back out, until the next time. They tend to blame it on the gas cap thing, but I don't really but that one. Other than that, great car, I'll by another one.
  • mikeusamikeusa Posts: 1
    I have 99 sonata GLS (V6). It pretty much like some sensor problem. Probably oxygen sensor and ECM (Electronic Control Module) programming problem. Believe me. You will have much rough time driving this car without fixing it. Sensor and ECM does not cost much (about 40-140~~) Fix it!! Dealers lies!! Especially about ECM!! (Since Hyundai does not pay much about this service and your is for free!) You probably end up paying diagnostic fee and done nothing. ECM must be fixed at dealership. 99-2002 sonata was pretty reliable car except for sensor problems. (Which is minor). Go to another dealership or get diagnose in outside autoshop.

    This isn't exactly a problem, but I cannot find where is the thermometer on my 2006 Sonata GLS V6. How do I tell the external temperature?
  • bobadbobad Posts: 1,587
    Sorry to tell you this, but the GLS doesn't have an outside thermometer. It's part of the LX automatic climate control package. The outside thermometer is the only part of the climate control package that I would like to have. :)

    You gotta luv 'em.
  • falvarezfalvarez Posts: 5
    I've got a 2002 with the auto climate system and it has had problems since I got it...I've had it in 4 times in less than 3 years and they have never fixed it is just out of warranty and now they think they know what is wrong but I have to pay to fix it...anyone out there had the same issues and been able to resolve them...I'm at the point where I'm just going to get rid of it and never buy or recommend a Hyundai to anyone...thanks
  • fk322fk322 Posts: 15
    If you have had this vehicle in for the same issue under warranty and it was not fixed properly, Hyundai should treat this as if the warranty is still in effect. Good luck.
  • ray_h1ray_h1 Posts: 1,134
    If you kept the warranty claim service tickets on your previous attempts to have the malady resolved, Hyundai is obligated by law to to take care of your original problem. Without those service tickets (which are proof of good faith on your part, but some dealerships avoid writing anything up to avoid a paper trail if they don't want to bother with what they consider a "nuisance" complaint), you'll have an uphill battle now that the warranty period has passed. Good luck - I have a feeling you're gonna need it.
