    I'm surprised the TPS hasn't provided a warning for low tire pressure. 27lbs is much too low.

    The TPS NEVER came on, even when I picked up my car at the Dealer. When I got home, I checked the air pressure, and each tire had 23psi. I never saw it come on. I will report that to the dealer on Monday, when I take it in to have them check the tires for noise.

    I have a 2011 GLS, now with 14,300 miles. Over the past year I have noticed the interior getting noisier and noisier. When new it was very composed. Some light road noise, but nothing major. Now it is a whole different story. Just plain noisy on anything other than pristine, freshly paved asphalt.

    I keep the tires between 34-35psi. I have started to notice the rear has a distinct oscillating "thrum" noise when driving over 40mph. No vibration or anything, just a constant "thrum-thrum-thrum-thrum". Could be a wheel bearing failing or could just be the tires...not really sure at this point. The car is just noisy.

    Another indicator that it is getting noisier is that I used to keep the stereo volume at "9", but over the past few weeks have needed to use "10" or "11" to clearly hear radio programs over the road noise. Also needed to increase the Bluetooth volume to hear phone calls.

    If I end up keeping the car much longer, I may have the dealer look into it. Based on the current list of issues I have with the car, it would take the dealer a week to sort through it all (the dealer has already said the one problem I have will require complete removal of the dash to fix)....might as well add the rear tire/wheel noise to the list. :cry:

    The 2011 Sonata has a little lever on the lock inside the trunk which makes it impossible to open the trunk without using the mechanical key. The electronic part of the key can thus be used as a valet key, and cannot be used to open the trunk.

    I have looked at several other cars recently, including some much more expensive. I have found none so far which offer any way of securing the trunk from anyone who has access to the cabin. Older cars often have some way of doing this.

    I think this little item does not get enough publicity.

    I think this

    Bought mine in Dec. I have a leak and was given the same story. I went to the car wash and it leaked even more. Has anyone went through the car wash and had the same problem?

    I saw the switch for that on the latch and while I wondered what it was for I really didn't give it much thought. But when the wife came home just now with the grociecries I tested it out. When in the lock position even the fob will not open it, just the key.

    I wish we had that on the rag top.

    There are three types of people in this world. Those who are good at math and those who are not.

    Most likely tires. Even Michelin had a big problem with this a few years back. I road in a FWD GM that sounded for all the world like a rear wheel bearing going out. Sound completely disappeared with a tire swap.

    Don't know exactly what causes this. My Khumo are doing the same thing after 18K of very even wear. I do know that unibody (no separate frame) vehicles of all makes are more prone to this.

    Does the "quality" or "tone" of the sound change depending on pavement type? By that I mean does the sound have a different tonal sound on new vs older asphalt or on concrete? If there is a significant difference depending on pavement type, I would lean more toward tires causing your noise.

    I agree that the tires are probably the culprit. It is a shame that they have become so noisy after only 1yr and 14,300 miles. I would expect noticeably more noise after 30K miles or so, but not this soon.

    The OEM Kumhos are wearing very well, although I would probably be inclined to replace them when needed with Michelin Primacy MXV4. The Michelins are the same price as the OEM Kumho at Tire Rack.

    The oscillating thrumming noise is always present, just louder at higher speeds. The tires are getting rotated this morning. It will be interesting to see if the thrumming moves up front or stays in the back.

    The tire noise itself does vary depending on road surface. Fresh asphalt there is very muted tire noise. Old asphalt, concrete, or grated surfaces the tires are super noisy.

    Follow up on my previous msg. on my noisy tires. On May8, I went to Discount Tire, for them to check my Kumho tires. I have almost 1200 miles now. "They asked me if I felt any vibration or pulling. I said no. Then they said, well, its probably the rated B, which is hard compound in the tread that is causing the noise. They did no checking at all. Then, I went to Texan Hyundai, my dealer. They test drove my car, and came back, and said, yes, we hear some noise, but it is not excessisve, just normal. So, I guess I will live with the noise, until I trade this sucker off, or have different tires put on. I also asked the dealer about the down shifting that I feel as I am decellerating. It feels a little rough, as I decellerate below 40mph. I can feel as it downshifts into each gear. I don't like that. The dealer said that was normal, too.

    I just purchased a Sonata and I am having a hell of a time getting the weather data service activated. On the radio, the button is there next to the traffic, stocks, and sport buttons, but it is not activated. Sirius tells me the radio is not equip to handle the feature. Yet I see some customers out there whom have purchased the service with no problems.

    Is there anyone out there with this issue? I know it is on a 3 months free service but I want to purchase the Weather data feature and for some reason I can not. Anyone out there have this issue or whom have the weather service, please let me know. :cry:

    It should all be free for three months. My weather worked for my free time.

    Does your car have the Nav. system? If it doesn't that could be the reason the weather doesn't work Just a thought.

    I received a recall update from Hyundai saying I needed to have the steering software updated and also had no steering problems with my car.

    After the update the car still drives fine, if not even better.

    The weather features costs extra on top of the Music Subscription from XM Radio.

    why don't you let somebody else drive it for a week and you take the bus (or switch cars), see if that person develops the same pain and yours go away.

    have you seem a doctor, the problem could be in your body? hope this is not the case.

  • hjc1hjc1 Posts: 183
    Yes I know this........... I still have about 3 weeks left on my free subscription and the weather works. I have the Nav. system and the weather description changes when I move from one area to another so it must be tied into the Nav. system somehow. If your Sonata doesn't have the Nav. system how would it know how to give you a weather update for your location.................
  • petdogdfwpetdogdfw Posts: 26
    To my knowledge you can only receive the weather if you have the navigation and specifically subscribe to that service. Since it uses the navigation to determine your current position, it is able to get the weather "local" to you current location.

    The weather feature is really a nice feature, but when I realized how much more it costs, I decided not to renew it in my subscription.
