#92 of 494 Re: Ref: Hyundai Front Suspension "Thunk" [backy]
Jun 06, 2008 (5:09 pm)
I get a definite thunk from my right front wheel when I go over the two speed bumps at work at about 10 mph. I drove over to the dealership where I purchased my 2008 Sonata. I searched around their location for speed bumps that would produce the same thunk. After trying to reproduce the annoying thunk at about 6 different bumps, I finally gave up. It appears that the car responds to a specifically shaped speed bump or just the right sized pot hole. The speed bumps at work are about average sized. I have gone to work with my old 1993 GMC half ton and my 2001 Oldsmobile Aurora. I tried and tried to get them to tunk but no luck. My thunk seems to occur when the shock is fully depressed. The weird thing about all this is when I did the speed bump test run around the dealership I fully depressed both front shocks at some rather large bumps with no thunk. It is kind of hard to get the dealership to do something about a problem that I can not reproduce when taking the service rep for a test ride. I plan on doing another search in the dealerships area. My work location is a half hour drive from the dealership. I am not giving up on this because it will only get worse with an increase in mileage.

If it's just the right front, it appears there's a problem on that side of the car. If it were the normal suspension noise, it would happen on both wheels, right?
#94 of 494 Thunk?

Is that a technical term or something? What the heck is a "thunk?" Can someone please describe the sound they are hearing with some detail, as "thunk" tells me absolutely nothing about the suspension noise you're hearing.
I bought an 09 Limited V6 and the car is a little stiff over bumps. That is to be expected, as I understand with the 09 Hyundai tuned the suspension on the sporty side. It's a fair trade off for the wonderful handling of the car. However there is no abnormal noise from my suspension at all over any bumps. Granted I don't drive quickly over bumps either. Maybe whatever issue existed has been fixed for the 09 model?

That seems to be the consensus.

The consensus of who? I have not seen anyone who has experienced hearing the thunking issue in earlier model years testify that 09's are exempt. Have you? The testimony of those who say they never heard it in the first place holds little value since it is far too easy for one who has a financial interest in Hyundai to post disinformation on this or any forum.

I've never heard the "thunk" on about a dozen 2006-8 Sonatas I've driven--test drives and rentals. I have no financial interest in Hyundai.
#98 of 494 Still No "Thunk" Description
Jun 07, 2008 (6:38 pm)
The only financial interest I have in Hyundai is getting my car paid off in five years.
Still waiting for someone to describe this "thunk" sound. If no one can do that I'll assume it's in their head rather than a real sound. Cars make noises going over bumps, that's just the way they work. I suppose unless you're driving a Rolls Royce, which I understand makes no noise going over bumps, for the rest of use working class stiffs, our cars will not be silent driving over rough patches of road.
Well this thread seems like a whole lot to do about nothing. I think people are way too paranoid and just need to drive the car instead of worrying about every little noise they hear. These are $25,000 cars and under, thus any noise I hear will be viewed from that perspective. You want perfection. spend $350,000 on a hand built Rolls. If there is some serious suspension design flaw with the Sonata that could affect it's safety, I'm sure we would have heard about it by now.

The best description I can think of to describe the "THUNK"s a kin to the old ball joint crunch when the ball joints were worn and you made a turn or something like that. More than that I cannot describe the sound to you, maybe someone else on this forum has a better description than that.

dgs4, your new '09 has an even stiffer suspension than the '06 to '08 gen?
If so, that is really depressing me.
In an era where the roads seem to be getting worse and worse, I was looking to get into a vehicle that has a smoother, less firm, less noisy ride. Although I can not stand the Toyota Camry, and think it's far more boring than the Hyundai on the inside and outside, I do have to give Toyota credit for giving the Camry a true luxury car ride with luxury car quietness.
Maybe I'm just getting old, or maybe the roads really are getting worse, or both. But I'm wanting more insulation from the crumbling and cratered roads in the U.S. lately, not less.

Some complained the 2006-8 Sonata was too "floaty", so the suspension was tweaked for 2009 to be more responsive. But from reviews I've read, it still seems to offer a smooth, quiet ride. I am looking forward to driving it. Maybe you could take one for a test drive and see if it offers enough insulation from the road for you?
