| Bought a 08 Sonata Limited about 2 months ago. Tokk about a week to realize that the thunk was not "normal", and now it is driving me insane. Had the dealer (private, not Hyundai) drive it for a day. He said it sounded "normal". Took it to the Hyundai dealer and they said they could not re-create the noise. Went back to the dealer and took the tech for a ride. he said he heard the noise but said it was "normal" and that all of them sound like that. Tried to be acceptful and live with it but it is still driving me nuts. Called the Service Manager yesterday and he said that the suspension on these cars was "sporty' and therefore more noisy. Then I started on a roll and told him about all the internet posts about this and that I could not beleive that he did not know about "the problem". he said to bring it in again and they will "see what they can do". My guess is that he knows exactly what I am talking about and he hoped that I would be like most of the other folks who just live with the noise or don't realize it is abnormal, but that is NOT going to happen. I'll see what they say, but anyhting less than all new struts and mounts would be unacceptable. I'lkl pursue this as long as it takes. This is a great discussion and I wish I knew about it before getting the car. The sad part is that I love this car except for the "Thunk". | |

Well they replaced my gauges. However, when I spoke to the service manager again, after hyundai consumer affairs referred me back to him, he gave me the same old answers. The tech found nothing wrong. The car makes no abnormal noises. I showed him the part numbers for the redesigned struts. He said that was for the 2006 model not the 2009. I asked if I could drive a different car. He said they had no 2009 cars. I would have to drive the same year car to compare them. I said why not a 2010? They are the same. he said a regional manger would have to ok it and be there. I said ok, get in touch with him. He said he would let me know when we could do this. I guess I'll be getting no place with this.

Took the service manager out yesterday. He acknoledged the clunk and he knew exactly what it was. He basically said it is bothersomne but it is a design problem and it is what it is. I'll follow up with the Hyundai complaint process but I've basically resigned myself to live with it until I unload it next year.....my solution...crank the radio!

Replying to: espo35 (Nov 12, 2009 5:52 pm) Assuming it is a design issue, it might only manifest itself in some cars. Perhaps the design issue is in the way the suspension components fit together--the tolerances in other words. It might be hard to align the components properly at the factory. Or they are susceptible to getting out of whack after a time. But if everything is done just right at the factory, there's no problem and no unusual noise. Here's an example of how this could work, using another well-known issue with a Hyundai. The 2001-6 Elantra is known for having an issue with front wheel "shimmy". Only some Elantras have this issue, and some don't have it initially but develop it later, e.g. when tires are rotated or rebalanced or replaced. I have personally experienced this issue on the two Elantras I owned (still have one). In each case, there was no wheel shimmy initially. But when I replaced the tires or had them rotated and rebalanced, the shimmy showed up sometimes. A careful rebalancing using a specific kind of Hunter balancing machine fixed the shimmy each time. But some owners have trouble completely eliminating the shimmy. The theory on this is the design of the Elantra makes it more susceptible to even a small out-of-balance condition on the front tires than on most other cars. |
