#167 of 183 k-thunk noise? by ghost2007 Apr 11, 2007 (8:27 am)
Hi,   I just bought a used (near-new) sonata V6. I think I may have the k-thunk problem. But it maybe just a noisy suspension. Is there an easy way I can findout if my can has this problem?   Also, I definitely have the sloshing fuel problem. Does Hyundai have a fix for this?   Thanks.

Replying to: ghost2007 (Apr 11, 2007 8:27 am) Go to your dealer and ask them to run the VIN. They'll tell you no you don't have the problem but be persistant.   Gas sloshing - no fix.   Congratulations on your purchase! Welcome to the club.

Replying to: ghost2007 (Apr 11, 2007 8:27 am) The K-thunk problem IS a noisy suspension.   If it makes a loud knocking sound in the rear when going slowly on bumpy streets, you've got the K-Thunk. If you have it, you are always sure you have it!
#170 of 183 Thunk & Rubbing Noise on Right Turns Only by sactojlm Apr 14, 2007 (6:28 am)
After reading through all the 169 posts so far, the common complaint seems to be K-thunk, thumping noise, torsion bar under stress or the dreaded clunk. The fixes have been described as rear shocks, strut mounts, rear suspension, new struts and mount brackers, new shock inserts. Finally, there is a TSB 06-01-011 that applied to Sonata equipped with the 3.3L V6 engine that involved the replacement of both rear shock absorbers. My problem, with a 2007 Sonata with 4 cylinder engine, involves rear noise, sometimes a thunk sound and sometimes only a metallic rubbing sound, that occurs on 90 degree right turns only. Is this related? Any diagnostician who can help?

Replying to: sactojlm (Apr 14, 2007 6:28 am) I've heard of a brake noise in some of the Sonatas. The only noise I hear in my car is gas sloshing and sometimes that sounds like a thud. I'm glad I don't have any of the problems others have noted.   BTW just how fast are you going when you turn right?

Replying to: sactojlm (Apr 14, 2007 6:28 am) Just a stab in the dark, but I'm gonna guess the sound you might be describing (metal rubbing) might be the wheel bearings?? Possibly not greased properly from the factory? I also have the I4, but an '06. The suspension is not the quietest, although I wouldn't really call any noise mine make a "K-thunk". Other than that and the occasional gas sloshing sounds, car is great! Replies to this message: craigbrooks (Apr 16, 2007 6:56 am) pekelopd (Apr 17, 2007 7:20 pm) craigbrooks (Apr 19, 2007 2:47 pm)
