Any of you guys having trouble keeping your i30 on the road if you hit a bump. I recently hit a bump in the road with my car and it was like the backside was on a waterbed, floating all over the road. Seems like the floaty back suspension is a problem in the i30 and in Hyundais overall.

[Doggie 1]

No.

[Phil №❶]

Our suspensions in Australia are different to yours, if anything, I find the suspension a little taught, but the handling is excellent as a result.

[i30RSA]

@DB08 - Well im quoting this guys post:

20mm rear sway bar fitted to an FD
March 15, 2013, 08:13:09 »

'I can notice no change when driving over speed humps with a single rear wheel. This should cause the side of the car that has the wheel on the flat to "squat" a little (more than before) and potentially cause a greater rocking motion. The same thing (but opposite direction rocking) should happen when a back wheel falls into a pothole. As both these things can only occur when the car is already being unsettled both front and back, it's likely that any small change here is effectively masked anyway. So no discernible difference for general driving. I also travelled the road between Mortlake and Warnambool, a truck route, which has lots of broken surface, ripples and sunken dips. It was unpleasant to drive on but it was always so - again, no difference'

My i30 does what he said in the first paragraph

[i30RSA]

@Phil - What distinguishes your suspension from mine ? As far as I know both our cars are build in Nosowitsch in Czeck Republic. Yeah, mine also handles great until it encounters a bump or a pothole in the road, which is when it sways and floats like a fat woman on a stippers pole  I recently had a loaded car and the entire car dropped past the tires, suspension doesnt seem that stiff to me !

I was so excited to buy this i30 and now its giving me more headaches in the first 3 months than the 2letter German brand gave me in a whole 3 years.

[Doggie 1]

I was saying no in answer to your question:

Any of you guys having trouble keeping your i30 on the road if you hit a bump.

On my second i30. I'm used to driving many, many different types of cars, including high performance cars, and I have never had trouble keeping either of my i30s on the road. Not even a hint of trouble.

[Phil №❶]

Our cars are different, Australian cars are manufactured in Korea, not Europe, the new wagon just released however, is from Europe, a first for Australia. Suspensions for Korean manufactured cars are definitely beefed up, for Australian conditions.

Our Aussie cars (Mine, Phil's, DB08's etc) are NOT built in the Czeck Republic. They are Korean.
And the suspension has been modified to suit Australian conditions. Stiffer springs and shocky rates AFAIK. Certainly mine is as stiff and rides as well over bumps as its predecessor, a Subaru Impreza RV.
A couple of Aussies have modified or expressed an interest in modifying their roll bar but when you read through all of their posts as I have done over a couple of years you (well, I at least) form the opinion it's more "just because they can" than a desperate desire to fix a fault.
So, again. The answer to your question is "No".

[i30RSA]

I must admit its a great car overall but as for the engine problems I mentioned in another part of this blog and for the floaty jumpy suspension, thats problems I never had in the other cars I had. Well, lads, Aus by far has better road conditions then us here in RSA, at least your government or municipality keeps your roads in a reasonable condition BECAUSE THEY HAVE MONEY, I had to personaly fix the potholes in my street with concrete and tarr after I lost a tire on a sharp edge on the pothole, got pissed waiting for the municipality to come fix it, which they promised to do get this 2 years back already, their reason, they dont have money and the machinery got stolen !

Im not too up to date on the suspension thing but too my knowledge the i30 has a torsion beam rear suspension which makes it jumpy and twitchy whereas other brands has independant link rear suspension which is a dare I say 'more advanced' setup then the torsion beam suspension in the i30.

Why Hyundai has to cut back on cost and fit outdated suspensions to their cars I would never know, on that matter the $35 000 South African version of the Santa Fe doesnt even have Bluetooth or RDS and then you get the cheap i10 whic has both ! Whats with that !

[Phil №❶]

AFAIK, the European cars still have independent link suspension and the Australian Korean cars have moved to torsion bar. So, far, there hasn't been very much said about the differences between the two suspensions except that theoretically, the independent link is considered slightly more refined.

[Doggie 1]

Can't pick any difference in day to day driving.
Plus I'm hoping they've solved the inner tyre wear on the rears by switching.

[Just Rick]

Both my I30's were manufactured in Korea,no floatie suspension in either of mine,two of the best handling cars I've driven with out modifying the suspension,if you really want to drive something with a floating suspension,buy a ford any ford,now to me they are wallowing whales,but no the two I30's I have are great

[Asterix]

Hey i30RSA

If the i30's in RSA have the torsion beam rear suspension, then i think they're also produced in Korea..   Should be visible on the VIN sticker.

Here in Europe we get the cars from the Czech Republic with independent rear suspension.

If you think your car is too floaty, then you could get a set of lowering springs fitted, that would certainly help a lot.

[Keith]

My Korean built FD has independent rear sussies and definitely isn't floaty!

[AlanHo]

The GD i30's from Korea and the Czech Republic have both got independent rear suspension. The Europe built cars have a sophisticated multi link suspension, the Korean build have a torsion beam. Both versions have been highly praised in the motoring press for their ability to soak up road bumps without shock or disturbing the car's road manners.

I cannot recall anyone else on the forum having major problems with "floaty suspension" which leads me to believe that i30RSA's car cannot possibly be a genuine Hyundai - but a cheap and nasty Third World Country copy. These criminal buggers no longer confine their activities to copy watches and perfume - they copy just about anything nowadays.

[i30RSA]

Ha ha ha ha im cracking myself up, yeah probably like those BMW and Mercedes ripoffs you get in China, especialy in Shanghai I did pay a crap load of hard earned money for my car from a big and well-respected Hyundai dealer in Johannesburg, so im sure its a genuine Hyundai 

Well enough bitching and moaning for a day. Will keep you guys up to date on my Korean nuclear missile (the car) waiting to explode in my garage !

Interesting way you describe the after effects.
So I can get a better understanding of this:

What was your speed at the time?

Did just 1 wheel hit the bump or a combination of wheel and was it both axels, i.e.front or back, or just 1 side, left/right?

Bump: -
Was this a hole in the road surface?
 or
a "speed bump" like a purpose raised part of the road to keep speeds low, i.e speed calming?
or
the road surface not flat and parts have raised due to wear/tear/weather?
or
something else?

Hi I've just joined today, glad I have found this post as I've only had my I30 for 4 weeks and my suspension feels wobbly and when going around corners if the roads got any defect on it the rear seems to hop giving the feeling of the rear sliding. I have lost confidence going around bends and I have to slow right down.  Also the tyre noise and vibration in the cabin and on the steering wheel is driving me nuts, going to take back to dealers ASAP to check it out.

Hi Fox, I believe you are in the UK... I am surprised to hear you say that. Although quite a few complain about the road noise particularly in the series 1 i30 most are more than happy with the handling.

[fox2015468]

Yes in UK, I'm new to Hyundai, never had a car that handles like this that's why it stands out so much, I do a lot of town driving for my job so all the streets have there own defects, feel like I'm rocking from side to side every time I hit a defect on the road.

[Phil №❶]

Welcome to the forum fox2015468,

Something doesn't sound right to me. Did you notice this behaviour when you tested the car before purchasing. In Oz, I find the handling, one of the car's many good points. Our suspensions are tweaked here though and can be a bit tight, in fact.

[eye30]

hi and welcome

it may help if you can let us know:
how old the car
is it the current model
petrol or diesel
mileage

[AlanHo]

Check that all the wheels nuts are tight.  I once collected a Toyota from a scheduled service which felt distinctly odd and there was a loud chattering from the wheels. I turned around and went back to the dealers. They found that all the wheel nuts were loose - they had swapped the tyres around and the mechanic had spun the nuts on finger tight and forgot to tighten them with a wrench. The wheel studs were necked because the wheels had moved off the flange. All the studs had to be replaced.

hi the car is 1 year old and its the new model, its the 1.6 blue drive crdi manual, mileage is 17500. purchased from hyundai dealer, previous owner was erac uk ltd, was told it was an ex company car just found out erac uk ltd is enterprise car rental, bit miffed now because car could have been abused and could be a clue to the suspension situation, also feels like the clutch isnt 100 % either, dreading contacting dealer i know they going to fob me off

hi , checked nuts all ok thanks for suggestion

[Phil №❶]

It's still under warranty, so any detectable faults have to be repaired.

[eye30]

contact the dealer and ask them to obtain car history

[Keith]

Where in the UK are you Fox? I'll lay odds there is a member close by who could help put your mind at rest, I'm in Telford, Shropshire if you are nearby.

Hey i30RSA

Yes the European i30s had multilink rear suspension since they started production. Some say it was a near direct copy of the VW Golf. I've never had any problems at all.

Please post a pic of the VIN sticker if possible, that might be interesting. I'm told that some Hyundais are assembled from kits in Egypt, maybe they found an old Hyundai Colt rear suspension lying around and bolted it to your car.

Thanks Keith  but I'm in nottinghamshire, Will see if anyone is local.
