my car also has same problem. i can see the steering wheel turns left as soon as i took my hand off the steering.
i was kinda ok with it till now. but it is getting worse. i am planning to meet the hyundai service this week.
Yes, from reading posts here in the past 3.5 years, and from MY experience --- it's the nature of the beast. At least this beast, called Sonata 4G.but it still wants to go with the curve of the road. Maybe that's just the way it is...?
Update on my situation. I just had 4 new snow tires put on. I put them on the same rims as I am looking to get some nicer alloys in the spring and the original tires were already fried (more on this later). Picked up the car and was anxious to see how it drove. On a flat road straight as an arrow - definitely better than the old tires confirming that at least one of them was "bad". Then I got on the highway (Queensway here in Ottawa) and in the left lane it was still "pulling" a fair bit down the slope. In the right lane it barely drifted at all to the right. However this highway slopes quite heavily to the left in the inside lane so some imbalance is expected. I drove my wife's Accord down the same stretch and it wanted to go down the slope as well, but not as much. So I took the Sonata to an independent guy I trust to do a 4 wheel alignment as I felt it wanted to go down a left slope more than a right slope (which may not be really true as I can't find a road that slopes as severly to the right). My wife picked it up so I have not talked to the guy see what changes were made, but it seems a bit better balanced, i.e., not quite as hard down the left side and a little more drift down the right side - still very straight and steady on a flat. At this point I am not really happy but I believe this is as good as it is going to get. I believe the Sonata chassis is more sensitive to road crowns than a better chassis car such as the Accord, and unfortunately I spend a lot of time on a road that slopes quite heavily to the left.My 09 V6 SE (GL Sport) pulled bad to the left when I picked it up (it was a demo with 10K km on it). I brought it back ASAP and they said "yep, alignment is out" and they fixed it. It was better but still net pulled to the left. I brought it back and the mechanic took it for a spin and agreed it was pulling. He tweaked the alignment a bit (but it was already in spec after the first fix), then rotated tires around and fiddled with pressures and got it not too bad. Then on one of the services they rotated the tires and the pull to the left is back. Therefore I suspect I have a bad tire (belts can shift) so I am biding my time until I can put some good rubber on it.
I also find the Sonata is more prone to pulling down road crowns than other comparable cars like the Accord. Again it might be the tires. I am hoping a good set of rubber will settle this down. I have to put snows on later this fall so I will have an idea then.
I did have a bad tire before because when the tires were rotated the pull would be worse or even change sides. With new tires it behaves much better.The "crown" business is garbage. Unless a tire truly has a slipped belt it is probably not the problem, although it is possible as I have seen this before. But swapping from front to rear ought to rule that out as well.
Just my $0.02.
Actually my 1996 Ranger didn't pull even on "crowned" roads. For that matter, neither does my 2008 Sonata. Only the 2009 does (slightly.)I did have a bad tire before because when the tires were rotated the pull would be worse or even change sides. With new tires it behaves much better.
The left lane on the highway I drive is very sloped and I can guarantee any car will drift down it, even your Ranger. My Sonata drifts worse than my wife's Accord, but the Accord will still go down this slope. On a relatively flat road (flat to minor crown) my Sonata is straight. When the dealer did the first alignment he showed my the numbers and they were all in spec (according to them). I still need to talk to my independent mechanic and see what numbers he got but I suspect they will be in spec.
The Sonata is an older design and the chassis was never a great design in the first place. It is simply inferior to other cars like the Accord and Mazda6 for this issue plus others such as suspension compliance (suspension clunk anyone?) and overall handling. For me I was willing to make this tradeoff for the other things I like about the Sonata.
I am not quite done with this yet. I still think it pulls down a left slope more than the right. I am going to go to the dealer and get them to let my try another one off the lot for comparison. If the others act the same then the final conclusion is the car design is simply inferior. If the other car(s) behave better then I will have some ammunition to get it fixed. At the end of the day I am OK with what I have now as long as the tires wear properly.
Wonder if that issue actually has to do with the dreaded torque steer, which already affects many FWD V6, not just Sonatas or other Hyundais. I was almost positive that may be the case here, until someone dropped that his/her I4 has the same issue...
Anyway, just consider that possibility; if that's the case, I'm afraid there's not much to do (some car makers engineered their cars to compensate for that pull -in some cars being really strong-). I think a good test to see if it's torque steer would involve checking whether the pull is much stronger when accelerating, while it should be minimal to none while coasting.
Just to clarify the NF Sonata does not use a MacPherson strut suspension it uses double-wishbone at the front and multi-link in the rear. It is actually a fairly advanced setup although the tuning and implementation may not be up to everyone's expectations.I'm not sure what you mean about an inferior design. So far as I know most modern front wheel drive vehicles use the MacPherson strut arrangements and it is pretty much standard issue stuff. My 2008 Sonata is as solid as a rock even with 25K on the odometer. I've yet to find any real problems although I believe the 2009 model has much improved ergonomics and detail changes that make it a more desirable vehicle.
Appreciate the information. That's what I get for making assumptions.Just to clarify the NF Sonata does not use a MacPherson strut suspension it uses double-wishbone at the front and multi-link in the rear.

I wonder which parts Australia got in their 2006 NF Models?Just to clarify the NF Sonata does not use a MacPherson strut suspension it uses double-wishbone at the front and multi-link in the rear.
