2010 Sonata

Had this car since new and it ticks every box but one. Ever since new its had an intermittent knock in LH rear suspension. Its not obviously, but it sounds like a shock absorber mounting bush has failed. Dealers have looked over the rear end and cant find anything. I,ve had a crawl around and cant find anything loose or interfering. Happens when a pot hole is hit mainly. Can a shock absorber make that type of noise?. Next step is to reverse the shockers to see if noise transfers to RHS. Anyone else have a similar issue?

Many thanks John

Never hear it in my 2010, but every once in a while, my 2007 had a sound like that. Did not happen often enough that I ever did anything about it. I figured it was a shock too.

Changed the shocks from one side to the other( top plates have to be swapped as they are marked L and R) and noise comes still from same side. What did surprise me is the low effort to compress shocks. Havn,t played with gas ones before but on my old aircooled VW you need major effort to compress shocks. Anyway back to square one! John

I thought I had this issue with another car a few years back. It turned out to to be the rear seat back was not hooked properly. I undid it and snapped it back in to place and the noise went away.

Try that!

Sway bar bushing?

My 2006 had a similar noise and it ended up being the sway bar bushings. They felt tight, but finally I had it jacked up one day while rotating the tires and I laid under the rear and pushed up and down as hard as I could on the sway bar and finally felt some slight looseness. New bushings cured the problem.

When you say "tried that one" do you mean you had the sway bar bushings replaced and the noise persists?

My 2006 also makes noises from the fuel tank when it is full or nearly so (above 3/4 or so). Not sure exactly why, but the sloshing of the fuel makes a funny noise.
