My 2009 Sonata Limited (1900 miles) is the worst car I have ever driven. This car when going over small bumps and road cracks makes noise like there is something loose. The dealer chnaged the shocks at 1400 miles, and still there is rattles and noise you would expect from a 20 year old car. I hate driving this car and use only when I must. It's a dangerous car to drive because one could easily lose control while driving, withs it's jarring effect when hitting bumps or road irregularities

I noticed this noise right away. I wish I had driven the car over bumps before I bought it. When the dealer changed the shocks was it front or back? Did this make any difference? I took out the trunk floor and left it out. Driving around seems a little quieter. I'm thinking it bounces around. It is not held down like some cars I have seen. I really don't want to change any parts if I can avoid it. I think sometimes it could make things worst.

So your dealer admits there is a problem with the noise. When I go back for the first oil change and will report the problem again. I had asked that they look at it when I picked up my plates. I drove the mechanic around. The roads there are not very bumpy. He said the car was normal. They also said they looked at it and it was fine.

I would describe the sound as "how a loose lid on a boiling pot sounds".

My question is...if we complain to our dealership/service department, does that go to Hyundai or do we need to call the 800 number to complain?
  
They changed my front strut assembly, insulator and some other washer and it made it quieter but we hear the same noise on either the front or the back now.
  
I'm going to check my trunk floor and maybe take it out to see if we notice a difference there.
  
Also, the BO smell is definitely coming from the window crack area. When driving with the windows up, you don't smell it...put them down and it's all through the car. I too do not like my car, which is a very sad thing. I want to be excited when I drive it....not aggravated.
  
Lenstang---maybe you can get them to ellaborate on what the service advisor means by "issues". We can tell them ALLL the issues if thye'd like. Right>?

I recently purchased a 2009 sonata and to have a very bad thumping from both the rear and front suspensions, and the front wheels feel like they are bouncing over raised bumps,it wanders all over the road at speeds over 50 MPH and vibrates at speeds over 65 MPH. I feel like I was taken!!!
  
Any info on a fix would be appreciated.

After driving around for a few days with the trunk floor out I found that it has nothing to do with the noise. I put it back in. I guess I'll report the problem again to the dealer when I'm there for the first oil change. It sounds a little bit like a bowling ball going into the gutter when I go over bumps. It's very annoying.
If anyone out there comes up with a fix please let it be known.
 
These comments, which I believe are very honest and representative and NUMEROUS, are why I'm completely abandoning the idea of buying any Hyundai.
 
Suspension issues and complaints are way more common in Hyundai than any other make of car that I can ever recall, and I can not believe Hyundai can't locate, reveal and fix the source of all these suspension noises and issues affecting so many of their models, and especially common on the Sonata.

Welcome to the world of Hyundai Sonata. I now have about 3800 miles on my car which came to me mid-July. Service mgr. says all is fine. That is just the way the car is made. I now know what Consumer's Reports meant when they said the car has "suspension noise". I too wish I had ridden the car over a surface with patched potholes and heavy tar lines before I bought it. The car is OK on smooth roads but not for the roads we have in W. PA.
 
Does anyone have a problem with static and interference on the AM dial? This car has the worst radio of any car I have ever owned or driven. Dealer made an attempt to fix this but only made it worse. I'm still waiting for service mgr. to get OK from Hyundai service to try something else. What a bummer as I listen to talk radio more than music. FM is fine but not perfect. Still has some background noise.

The Sonata is an inexpensive car. I have a 2009 and when you hit a manhole cover it is louder than my Nissan Murano but the Murano costs twice as much. I have not experienced any unsafe handling. It seems well controlled in my experience. The car is rated above average in reliability. Before I purchased my Sonata I looked at Honda's, Nissan's, Fords and Mazda. I believe the Sonata was the best value for my $18,000.

Ok, I have a 2009 GLS with 5 speed Manual Transmission. I have 1000 miles on it. Yes, there is some thumpa-thumpa over bumpy roads. But I wouldn't exactly call it something that is horrible.
 
I think a lot of people on here are blowing this out of proportion. The American car driver expects a fully noise insulated ride, something that can usually only be done at the expense of good handling and with a super soft suspension. Let's keep in mind this is a family sedan with a price point of roughly 16.5K with current incentives.
 
I also own a 2004 Mazdaspeed Miata (turbo'd / hard suspension). I would like to suggest that NOBODY on here complaining about road noise or loud suspension has any idea what a truly noisy car sounds like. Come take a ride with me sometime in the Miata and I'll show you what real road noise is all about. Not only is the suspension hard to the point where it becomes exhausting after an hour of driving over PA back roads, but your ears get a workout from:
 
- jarring ride over even the smoothest roads
- whining air intake as the turbo builds boost
- explosive rush of air on shifts when the system vents excess pressure
 
The Sonata is so quiet that I find myself uncertain what gear I'm in (remember, I bought a 5 speed manual) due to lack of engine noise. The supsension thump is mild, at best, and should be put into perspective.

I have talked to a good number of Sonata owners. I also have taken rides with
some of them. It seem that some cars ride better than others. I had the owner of a 2009 GLS take a ride with me just two days ago. He said his car, which is the same as mine even the color, makes less noise than mine. He said "you feel every bump in your car even the small ones". I also own a 2001 Toyota mini van. It has 40,000 miles on it. It makes much lees noise over bumps. The 1992 grand prix that the sonata replaced made much less noise than the Sonata. When I went back to the dealer for the first oil change they again told me that many Sonata owners say the same thing. But most owners I talked to said the ride was good. So I will be going back to the dealer after the holidays to try to get them to do something. I also
found my gas millage to poor. The best I have done is about 17.75 miles per gallon.
It was only 14.2 miles per gallon in cold weather of late here in New York City. This is all city driving.

One thing to consider, and check, is tire pressures. It may seem like a little thing, but tire pressure can make a big difference for ride smoothness and tire noise over bumps, especially with lower-profile tires as on the 17" wheels on the uplevel-trim Sonatas. If someone has their tire pressures a few pounds under spec and someone else a few pounds over spec (for better fuel economy or just mis-set), that could be a 10+ lbs. difference in pressure, enough to notice between two cars.

OK I try to ignore posts about "poor" fuel economy especially when I previously answered more than my share patiently explaining to persons, perhaps like you, who do not understand the toll of city driving (most especially NEW YORK CITY) on fuel economy. You drive there, I do not, but that driving experience (in my mind and feel free to correct me if I am wrong) is (A.) go like hell to beat out the taxi next to you..until the next light turns red (B.) repeat and/or don't move at all due to congestion followed by a free for all on the expressways into and out of the city proper until they too clog up due to an accident or something else. Do you think almost 18 mpg is "poor" under such circumstances? Please remember you are getting zero (0) mpg much of the time. With regard to cold weather...all gasoline vehicles perform worse with regard to fuel economy in cold weather due to warm-up periods (idling) you may persue to defog/defrost the glass and encourage heat to warm the interior before driving off, and a general longer time frame for the vehicle to warm to a more efficient operating mode. 17.7 is good and 14.2 is acceptable for the winter in all city driving. City dwellers need a hybrid in order not to complain about fuel economy.

What tire pressure would you think is best?
I try o keep it at the recommended 32 psi cold.

Smart move. It's not just how much you spend.
I would gladly have paid more for a better ride.
