have had an issue recently as you describe. I have not been able to track down the cause, (your suggested cause is very useful) but the symptoms are the same. Very bumpy and noisy like a bad shock. I will follow up with my dealer. thanks!!

Haven't noticed a deteriorating ride quality yet. It is most notable when taking a grade difference on the left side (where the bad one is located), like pulling into a driveway, parking lot, or angled railroad tracks.

Of course, I didn't isolate it until after taking off interior panels and exploring sound eliminating/deadening products and methods...

 

I had my 2 rear shocks replaced at 36k km because of a clunky noise. (2010 Tucson Ltd) Now at 50k, still no clunk from the rear. My dealer said at that time that it was a common problem. They didn't perform alignment at that time and 1 month later, my rear tires start to used in the inside so I had to pay for an alignment as my dealer said it can't because they change my rear shocks ... but I highly doubt about it.

 

I think I detect a little clunking somewhere in my suspension. Will have to check this out.

 

Have an appointment Friday morning. Will update with results.

 

Dealer confirmed the source of the noise as the shock assembly, but it was the upper shock mounts that were going bad. Parts should be in shortly for both rears under warranty. Will advise if they have to do the shocks too. Since the diagnostic appointment, they have continued to get louder.

 

Just got back from the dealer after they replaced the at-fault left rear shock and upper shock mount under warranty. Apparently the shock was also leaking a little. Glad to finally have that over with.

We have an appointment today for the same thing, but mine is the right rear.
It's a tapping knocking noise.

Hi Barry, did you discover the problem?
I have a similar noise in the rear of my IX35.

 

just to add about my car, I just had my 2013 GLS oil changed today 65k KMs)today and they told me that i'll need to have both rear shocks replaced because they leaking and also the bushings and sway bar links on the rear. This will all be covered under warranty.

Hi - 2008 Tucson - I have the same thumping problem with the left front corner; had lower control arms, bushings and ball joints replaced. Passenger side is now fine. Where to go from here? Struts, mounts or ? Thanks.

Finally found the source of the ultra annoying hatch banging. Removed every freaking panel, secured every single thing that could cause noise. After half dismantling the car, putting velcro on the cargo cover so it doesn't move, etc., banging noise remains. And yes, checked under the car to see if anything was loose, and wasn't. Was suspecting internal shock issues, but didn't sound like it could be it. Relieved to finally find the culprit. Will call tomorrow for an appointment. Will also demand an alignment, even if I have to pay for half or something. Also have an annoying rattle in the center console, but don't want now the front dismantled for that, so will let my daughter live with that (she doesn't complain).

So what was causing the noise?

 

Here is something I noticed looking at my daughters friend's 14 Elantra. It was making this thumping so I turned the wheels as far one way as they would stay and started shaking things. It took just a couple seconds to see what was wrong and it was dead obvious. There is a vertical link about 8" to a foot long. It's right behind the tire. Hers was loose as a goose which explained the thump every time she hit a bump or went over a rise in the road. You don't need to be a mechanic to feel this either, its quite obvious . just grab and shake hard. If it is shot it will rattle around and of course it should be rock solid.
Her car had under 30K never been wrecked or trashed a tire. I priced the link on Amazon and it was around 30 bucks. I didn't change it though it surely is stone simple requiring only a couple end wrenches. I can't see it being a safety thing. Just some annoyance that will drive you crazy. With those low miles it has to be a factory defect. In all the old cars I owned drove or fixed since 1973 I never saw any car with a link that loose.

 

2012 Tuscon 90000 km clunking noise from rear and insatiability when going over bumps at highway speeds. Dealer under warranty replaced rear shocks and sway bar links which fixed both issues.

 

I have this from the beginning on a 2011 iLoad. come to accept it as normal behaviour.
That and the rear dif on the van knocks

 

My front left strut got replaced at 6,200 miles on my 2014. I swear I didn't take it off roading or over curbs.
