Hyundai Sonata Maintenance and Repair



  • tomk17tomk17 Posts: 135
    My V6 LX seems to shift into 5th gear quickly and stay there a little longer than it should. Do I recall a TSB about shift pattern changes? I know most cars now are geared to get into 4th or 5th ASAP to improve mileage but I tend to get a slight shimmy when the car gets into 5th and the speed does not warrant it. Any advice appreciated.

    As far as i know - there is no TSB that take care of this - only one for 2 to 3 shift flare.
    Eventually se:

    or this:
    As far as i can read from your post - it seems similar to my complaints with this model.
    Have talked to a technician from Hyundai in Denmark, who for the time being is testing the 09-model, before it goes public here in Denmark.
    He says the problem is NOT soleved in the 2009 model - too bad - i really have hopes so...
    Think i'm going to test it for my self in the next week.

    I have a 2007 Sonata V6. The emergency brake became stuck this morning. I cannot release the lever from the upright position. It is cold outside, but no water is in the area. Any suggestions? Thanks. :confuse:

    My 2006 LX changes into 5th at about 40mph and kicks out at about 35... personally because I am on basically flat area, in NW Florida, I would have preferred it to go into 5th at about 35.... but.... that's life... I haven't had any problems with its operation however, but am very interested in whatever you find out.

    You may be on the right track. When you say there is no water in the area, what area do you mean? Could there be frozen slush in the area if the parking brake lever on the rear drum? The parking brake works on a small drum which is part of the rear rotor, I believe.

    I trust "old" style intervals of 3000 miles. If you do it yourself the cost is minimal. I would not trust an "indicator" telling me how much life is left in my oil. I've done 5000 intervals and had to pay for that. I'd rather go with what I trust. :)

    If you are curious about the maintenance recommendations you should refer to your owners manual. ;)

    I don't have the car or owners manual and I do not want to wait until after purchasing to find out these things.

    Different cars models require different amounts of maintenance.
    3,000 mile intervals is way overkill and is a waste of time, money and oil for the cars that don't require that schedule.
    I think that the Sonata might be one the car models that do require more maintenance than average and I will weigh that extra cost and inconvenience when comparing it to other cars.

    According to Hyundai's owner's web page, the recommended oil change interval is every 7500 miles/6 months unless it falls into one of the below categories:

    A - Repeated short distance driving
    B - Extensive idling
    C - Driving in dusty, rough roads
    D - Driving in areas using salt or other corrosive materials or in very cold weather
    E - Driving in sandy areas
    F - More than 50% Driving in heavy city traffic during hot weather above 90oF (32oC)
    G - Driving in mountainous areas
    H - Driving as a patrol car, taxi, or other commercial use
    I - Driving over 100 MPH (170 KM/H)

    We own two Hyundais and I get the oil changed every 5K to 7.5K miles and we live in south-central PA. Our driving patterns and environment would seem to dictate we should follow the severe schedule but when I asked our dealer's service manager said we would be OK with the schedule we use. YMMV. ;)
  • m6userm6user Posts: 2,897
    I would want the dealers OK for that maint schedule in writing. I would say that at times nearly every driver in the country could fall into the severe schedule by that criteria. Anybody living in the northern states during the the winter would fall into this. Anybody living in a major city or in mountain areas. It would be nice if it said the MAJORITY of driving in one of the catergories but apparently it doesn't. For a lot of people afraid of voiding their warranty a dealers "oh, you should be ok" doesn't really hack it.
    I know this might sound a little anal but over on the Mazda6 board there was someone who had their oil changed at a jiffy oil change place and kept the receipts. He was denied warranty engine repair because the reciepts didn't have the vehicle VIN printed on them. Who does that?
  • jaxs1jaxs1 Posts: 2,697
    The dealer does not set the schedule. The manufacturer does. The dealers very often recommend extra services not required by the manufacturer.
    If you are going to ask anyone, you should ask Hyundai to clarify what "repeated" and "extensive" means.

    It does say "More than 50%" of your driving in heavy traffic while temps are over 90 degrees.

    I don't do any of the things on the list regularly and many of those things never.
    There was probably something more to the Mazda5 story. Most work orders will at least have the license plate number and mileage. It may have been a 3rd party extended warranty company that was just making up excuses to deny claims. They would have to put that in their contract to enforce it. The person posting may have also just been lying about the whole incident.

    You can also send an oil sample to be analyzed at 3,000 miles to see how much longer you would be able to go based to your actual driving.
  • A - Repeated short distance driving
    B - Extensive idling
    C - Driving in dusty, rough roads
    D - Driving in areas using salt or other corrosive materials or in very cold weather
    E - Driving in sandy areas

    F - More than 50% Driving in heavy city traffic during hot weather above 90oF (32oC)
    G - Driving in mountainous areas
    H - Driving as a patrol car, taxi, or other commercial use
    I - Driving over 100 MPH (170 KM/H)

    C, D, E, & G have nothing to do with your motor oil and if you only meet one, or all, of them you can use the 7,500mile interval.
    Now what those 4 things cause you to do is look over the brakes, body, air filter, and suspension more often as they can be affected by those items.
    Just let my dealer try and deny any warranty work just because I change my oil at 7,500 mile intervals. I have the oil testing results to prove the oil is still in great shape, probably better that the oil they put in when they change oil for the poor fools that go to them, and they need to tear down the engine and PROVE!! that it was an oil caused failure pointing to my records and my 7,500 mile OCI's means/proves nothing.
    btw I had 300,000miles on my 4x4 4cyl using 7,500 mile OCI's and she was running as strong as the day she was new when I finally had to let her go.

    Is anyone aware of an issue with the 2003 Sonata having rear brake or wheel bearing problems during cold weather that would cause them to freeze? My brother-in-law has a 2003 that when it sits in weather below freezing, the rear wheels freeze and will not turn. Pouring warm water on the rotor frees up the wheel to drive and then it freezes again when the car sits. The wheel bearings do not make noise when driven.

    I can see that parts of D,and G could have an affect on motor oil. With "D" cold weather starts can possibly cause oil starvation and a lack of prompt lubrication to internal parts especially if the oil is old and thick with accumulated contaminents.
    With "G" since I do a certain amount of mountainous driving I can see the extra strain put on the engine. It is in a lower gear at higher RPM much of the time while climbing.

    I realize the dealer doesn't set the schedule....hence the dealer should have referred him to Hyundai for his answer. My point is exactly that---the manufacturer should be more clear in there criteria and not make people guess. Do you really think that if someone called Hyundai they would get a straight answer on this question or the same answer to the question if you called twice?

    There was a lot more to the Mazda6 story but I just stated the basics for brevity sake. No, it wasn't a third party warranty, Could there have been a detail left out or could the person have been lying about the whole incident? Sure. Anything on these boards has to questioned to some degree.

    The only thing I wouldn't question is a 3000 mile oil change. You can tout environment or whatever. The fact is changing fluids BEFORE they BREAKDOWN can only create longevity, happy owners and less hassles at warranty claim time. Being cheap up front really costs you later. I can attest to that. An oil change costs me $18.00 in parts plus my time and it lets me be one with the underside of my car. I like to know what is going on under there. Every few months is good insurance. Plus my neighbors all come out whan I have the hood up. Quality time.

    If buying a brand of car depends on the "maintenance" schedule I would suggest one with an oil life meter. You'll be happier it sounds like.

    I hope you wear protection while you're under there. ;)
  • Ok, I can see your point with item G in that your engine is working harder at a lower gear/higher RPM going up the hill but you also get to come back down and the load is less at that time. D I just think that if you are using the proper grade/type of oil for the temps this is not a big deal, but it is a good point. There are several 0W-20/0W-30 oils out there that should cover that issue. In any case a good synthetic oil is built for 15,000mile or better OCI's and there are a few that are rated out to 25,000 and even 35,000 mile OCI's in a normal duty cycle and 1/2 of that in a severe duty enviroment.
