Hyundai Sonata Maintenance and Repair



  • m6userm6user Posts: 2,952
    Somebody just had a bad day it appears. I know what you mean about hoping that someone may have had the same problem and maybe have a quick fix that would negate the necessity of making a trip to the dealer. We all know how pleasant that can be.

    However, it can be somewhat annoying reading the same post over and over again. Most people seem to visit most of the threads to keep informed with what is going on with cars so you can usually be fairly confident that your question got read and it's just that nobody has an answer or a similar problem.

    I changed the fuel pump on my Hyundai Sonata, which was not necessary for some reason it is not getting fuel to the engine there is no fuel smell in the engine compartment when I am starting it, what could it be? :confuse:

    I have a 2005 Sonata. Last night, both low beam headlights went out. Is it possible for both bulbs to go out at the same time? I checked the fuses and they look good. I haven't replaced the bulbs yet. Is this a symptom of an electrical problem in the car. Both high beam lights work good.

    A friend had a 2005 Sonata, and all the lights on the driver's side of the car went away on hers. Unfortunately, I don't have a good solution for you, as she sold the car because she couldn't seem to get it fixed. Seems like a weakness in the car though.
  • I test drove a 2009 Sonata for the third time. The demo had just under 1,200 miles on it. While going over a rough patch of road, I heard a loud snapping noise that sounded like a whip cracking. Even the salesperson freaked out. We both think it came from the passenger side, but that was a guestimate. It was very loud.

    I like the interior of this car a lot. Now, I worry about more suspension issues. Has anyone with the new Sonata noticed any similar occurrences? The car was built in Alabama according to the door tag.

    The idle was also rough when the car was in park. This was the inline 4 cylinder. The tachometer would fall to around 8 or 900, and then surge to 1400 or so for no apparent reason. This was after the car was fully warmed after the test drive.

    My other complaint is that the steering wheel feels gluey when turning all the way to the right or left. I don't know how else to explain it. It feels like its smooth and then all of a sudden resistant for a split second.

    Anyone experience these problems?

    I have never experienced that noise in my '09 Limited. Maybe, being a demo, it was beat on and something broke. :confuse:
  • nvbankernvbanker Posts: 7,285
    Cant help you with the noise, but the 4 cyl usually idles a bit rough, which is why I recommend the V-6. Runs much smoother, and only costs you about 1 mpg.

    I have an 06 Sonata GLS (4 cylinder) with around 44,000 miles on it. I've noticed in the last week or so that there is something "snapping" in the brake pedal occasionally when I press it (kind of like something is binding). It's not the ABS self test, and it has nothing to do with the shift interlock (that noise would be coming from around the shifter -- been there, done that). The brakes are otherwise fine, but the snapping feeling is a bit annoying. I'm having the dealer look at the pedal on Monday, but I was wondering beforehand if anyone else has any thoughts as to what might be wrong.

    I have a 2006 with 55,500 Km on it. In the last month, I will get this occasional “thump” when turning the steering wheel while braking pedal. I am now also getting a swishing noise from the driver side wheel well and a creaking noise when reversing. It is the same noise one gets from a train, sort of like a chugga chugga noise when going forward. Any help would be appreciated.

    I've experienced a similar "thump" issue while steering quickly at lower speeds. Mine didn't have anything to do with the brakes, though. The dealer replaced the steering rack, although I'm pretty sure it was just something in the system that needed to be lubricated. (I was certain the noise was coming from where the steering system was rubbing against something in the floor board.) As the car is under warranty, I won't complain about the cost!

    I'm not sure about the other noises you're experiencing, though. Perhaps you have a bad wheel bearing in the case of the train-like noise.

    I guess funny noises and silly little things acting up was the price we paid for buying a first year model (imagine how much worse it could have been if Hyundai didn't spend all that time developing it to begin with). I'm willing to give Hyundai a bit of leeway here because of this.

    Hi all. Ive had my 07 Sonata for 13 mos now and have racked up 20000+ miles. My MPG has been decreasing from 24.7 (max) down to 24.5 in the last few weeks. My last oil change man told me I should get my fuel injection line cleaned (at the one year mark of ownership) which could improve my MPG. Is this guy telling the truth? Any suggestions?? thanks!!!
  • nvbankernvbanker Posts: 7,285
    A 10 basis point decrease in mileage is a rounding error! Assuming you are extremely technical and accurate in your calculations with measured amounts of fuel between mile checks, it could just be the hot weather and more use of the compressor for the A/C doing that much change..... I would not fret. My my, if you're that sensitive, it's going to be hard to define for ya.... ;)

    I agree with nybanker. That variation is mileage is statistically irrelevant.


  • cabbycabby Posts: 8
    Thanks for the replies. How about the fuel injection cleaning? Is this something that should be done?
  • jprybajpryba Posts: 201
    Just buy a bottle of fuel injector cleaner for a few bucks and add it to your fuel tank the next time you fill up. It's worth giving a try and costs a *lot* less than the snake oil the dealer is offering!
  • nvbankernvbanker Posts: 7,285
    that I certainly agree with.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,405
    I'd try a different brand of gasoline just to see what happens--like Shell.

    You can use injector cleaner but not that off-the-shelf stuff at Wal Mart, etc. That's too weak to "unclog" anything---at best, they are just maintenance-strength. You'd need something truly toxic like BGK-44 if you can find it. That stuff really wakes up a lazy injector.

    Still I must confess you may be chasing a ghost here, giving the slight decrease in MPG over such a short measuring period.


  • Hi,

    When reading out the code from the ECU I get a code 41. The engine is not running smooth, but seems to stagger or hesitate at certain rpm's and varying load.

    Any suggestions

  • I have a 200 Sonata GLS V6. My Fan switch needs replacement and the dealer want $185.00 to do it. I was wonder how hard it would be to access the switch? It looks as though I only need to remove the center dash paneling (wood grain plastic) to get to the switch and pull a few connected wires. If anyone can confirm that the paneling is all I need to remove I'd appreciate it. Also I read somewhere in this forum that the paneling comes off w/ screw driver wedged for leverage to unsnap it from the dash. Is that true? Anyone w/ a shop manual out there?
