Sonata 06 3.3 Problems, tyre imbalance and valve clatter Options

[hdsit]

Bought my 06 Sonata 3 months ago, and have had and still have problems with the car (now 7400 km.)

1:
When engine is cold, there is a sound of valve clatter – goes away when engine is warm - Have had oil changed at 6500 km. – not better.

2: bumping from the tyres mostly from 65-70 km/h and forward.
The car was delivered with 225/50/17 Dunloop SP 270 tyres.

A: car delivered – back to dealer and balanced – still bumping
B: 3 tyres shifted to new (the tyres which was most visibly out-of-round) – balanced – still bumping
C. the last + spare changed – balanced – still bumping.
D: Optimization with Hunter GSP9700 – okay in two days (no bumping at 65-70 km/h – steer vibration at 110-120 km/h) – third day bumping again from 65-70.
E: changed all tyres to new brand GoodYear Excellence 215/55/17.
Balanced to 0 at the dealer – still bumping
F: Dealer and I tried to locate the problem with changing to 4 balanced and checked 215/60/16 tyres with no luck to get the car run without bumping.
G: changed one tyre which was most visible out-of-round – seems to be ok at this point at all speeds.
Very little bumping hardly noticeable – but now three days after, bumping is getting worse and worse, again starting at 65-70 km/h.

The dealer says that I have to drive about 1000 km – then rebalance the tyre again eventually finalising with balancing the tyres mounted on the car (don’t know what it is called in English something with on the spindle).

Is this car extra sensible to out-of-round tyres and Tire RFV (Radial Force Variation), or is there something else wrong.?

Have talked to two other dealer who both have the same problem with this model.
And the Managing Director for the importer of Hyundai in Denmark have the same problems - They have not yet found any solutions.

Any suggestion, or anybody have similar problems, and best of all someone who has “The solution” to this problem which is about to driving me nuts…

I'm still very happy for the car, and just hope that it is possible to get these problems solved.

Michelin tires are installed here in Canada & US. We don’t have this kind of problem here. Tell the dealer to fit Michelin or Uniroyal tires.

A similar problem was posted a couple of months ago in the thread "Streering Wheel Vibration". To summarize the thread, you may need to have the tires dynamically balanced which cannot be achieved on a regular balancing machine.

[MaytagRepairman]

Never mind. I think the Hunter GSP9700 does do dynamic balancing.

[hdsit]

Okay - the new set of goodyear tyres have not been dynamically balanced, just ordinary.
Now three days after i got the new tires on the car - they are back to just the same amount of bumping as from the beginning. I dont understand much anymore. I have tried earlier to have the dunloop tyres dynamically balanced, and it only lasted for a couple of days. - I can off course try to get the new tyres dynamically balanced too, and hope that it will last more than a couple of days...

Could it in anyway be something else than the tyres there is the problem?
The dealer says that the never have had any complaint with the 2.4 with 215/60/16 tyres.

I'm having serious considerations about the solution to suggest to the dealer to get ContiPremiumContact 2 on 16" wheels. - On my earlier sonatas i always drive with these tyres without problems at all.
I'm about to loose my patience ...

l can well understand your frustration, give one more try and get the goodyear's balanced

Hello hdsit. I'm wondering if there isn't something wrong with your suspension. Is it possible that you just didn’t create the conditions that cause the bumping when you first have the tires balanced, and only thought the problem was corrected, only to find out that it isn’t? I think the dealer should be looking at the suspension to see if something is loose. Hope you get this resolved soon.

Hi.
I have just came back from just another dynamic balancing with a Hunter GSP9700 machine - There was a little unbalance an two tyres was about 10-15 grams out of balance. - All set to zero. one tyre had a "load weight" or RFV (radial force variation) i guess it is called at 10.5 kg ~24-25 lbs http://www.hmaservice.com - TSB 01-50-008 "Tire and Wheel Vibration and Radial Force Variation" says P-Metric passenger car tires ---> 18 lbs or less), but he said it was inside the tolerances - the other three was around 5-6 kg. All tyres was visually round.
He said that this tyresize should have 40 psi (32 according to the manual) - and so he gave it that pressure. The car was very uncomfortable to drive with, as expected.
Still there was exactely the same bumping as before - I set the pressure down to 32 psi. - much better comfort, but still bumping specially in the interval 65-75km/h.

But not more, not less than before.
The "specialist" said, that the only thing he can see can be done is to try to balance the tyres on the car.
(But if that solution should solve the problem, it will just be a lot more expensive in the future to maintain ex. change to winther/new tyres - not a good solution i think...)

I have noticed something (not new - have always been there).
When i accelerate hard from 0 and up in gear one it is like the engine/transaxle or tyre is rough/bumpy - dont know how exactly to explain it...
It's just not smooth as silk as when i get up in second and third gear - seems that something is "awry"

I am wondering - is it time to get a replacement - a new car?
Or how many times is it reasonable that i try?
Off course there is no guaranty that the problem is solved by getting a new car.
But... - have never had so many frustrations before with my other sonatas.

Any good ideas?
Sincerely Uffe

Well - Next step i try now is:
My dealer ordered 16" OZ-Titan wheels and Continental Premium Contact 2 tyres -(free) - then i perhaps and hopefully also get a little more comfy ride with less tyre-noise. Have tried a 2.4 with 16", and i think it's ride is more comfy...

And hopefully get the other problems solved...

one other big issue here is that you are getting an outstanding amount of support from your dealer which is nice to hear for a change

Not only from my dealer.
I have also had a lot of talks with the Danish importer, specially their technical service, who have been very helpfull in getting me satisfied with this car.

Their statement from the beginning was, that i should be 100% satisfied.

My dealer has off course also been very helpfull, and they have also been used a lot of time and ressources in this case.

I have no complains at all on Hyundai in Denmark - Besides this is my fourth Sonata. Never have had any problems at all with the support and service.

Thats off course a heavily factor for buying this new car.

I will post a feedback with my experience with the new wheels/tyres -
Hopefully this is the final "Solution"... :57:

[geneallen]

I too have a new sonata. It doesnt have tire bumping but seems on bumpy roads to have more visible noize. Seems to be coming from the exhaust system or more like something bumping under the chassis.

This is the six hyundai I have had. I have three at present. My 93 Excel has been the best car I have had. Hundreds of thousands of miles... No Problems! Still gets 45MPG uses no oil...

I just know sometime soon it will die :(

Does Hyundai offer other tire options? My '02 Elantra came with those Michelin Energy MXV4+ (or whatever) and at over $100 each are the worst tires I've ever had on any car. They were shot at 35,000 miles, have no mileage warranty, would howl on just about any cloverleaf at any speed, and were useless in the rain and snow. I replaced them with Potenza G009's at 2/3's the price and it's like a whole new car.

The problem I have noticed on the V6 2006 is that around 43 mph the car has a very slight wobble feel, we have checked the tires and RF balanced. Still had the problem so put the cruise on when the problem occured, used the shif-tronic to see if the "wobble" would change under a different RPM but it didnt.

I test drove another and it had the same feel, any ideas?
[right][snapback]22802[/snapback][/right]

Same thing here. I didn't get it down to the exact MPH but yeah, it's between 40-45. It almost feels like (in mine) that the car is trying to decide if it wants to stay in 4th or 5th and ... dunno, hard to explain that. I have noticed that it only does that under slow acceleration. If I'm accelerating at a pretty good clip I can't notice it. Also, it seems to be gradually getting better - of course that could be my imagination.

[hdsit]

Finally got Continental Premium Contact2 tyres and OZ wheels mounted.
Tyre off course balanced to 0 on ordinary balancer
- The first ride was almost without bumping at all - Just a very small wobble at around 70 kmh /43 miles - hardly noticeable, specially in the passenger-side.
Drove around 400 km, and it get a little worse (specially i feel vibration in the steering wheel and in the passenger side).

Got the tyres dynamically balanced with Hunter GSP9700 again - approx 10-12
grams out of balance on three wheels.

RFV was 0,5 - 5,5 - 4,0 and 4,5 kg - which after what the specialist says, absolutely should be indisde the tolerances (he had never had problems with any "extra sensitive" cars in that range)

After balancing again hardly no wobble, and nothing to feel in the steering wheel at all. Not perfect yet but almost.

On tyre was a little visually "out-of-round", and the tread seems to "wave" a little from side to side while rotating. - Will try to change this tyre with a new (spare) on monday - as a last try. The tyres seems to be almost perfect.

The specialist told me that BMW had a similar problem once - then it was something with a bushing that need to be replaced.

Besides the new tyres gives a lot more comfy ride. Less transmission of roadnoise and much better to take up on rough pavement - And less "clunking" from the rear.
Maybe not as good feeling/sensitivity with the surface, but for ordinary driving - it's fine for me.
I primary bought this car for the great comfort, not exactly for a "sporty ride"

I will give a feedback on monday when i try to change the tyre that was visually out-of-balance...
I cross my fingers and hope...

i havent had any problems with the tire balancing ....car came with michelins and they ride very nice and smooth....i just got them balanced and rotated at 5k miles and they still ride smooth..dont know why you are having these problems...oh and continentals are shitty tires

[markn455]

No problems here. The ride is great at all legal speeds and higher.

Got the out-of-round tyre changed. Still a little problems with wobbling/jumpying at around 65-72 km/h - especially when slow acc. in 5'th gear - there it is rather noticeable.
I dont know if it is something i have to live with. I'm a little nervous that there is something else that is wrong with the car (that it is not tyre-related), suspension, bushings or what do i know.
I'm going to order 4 winther-tyres tomorrow (205/55/16 conti TS810), and that would give me another chance to find out if it is tyre-related or not.
As from other posts: Other post, and replys here i doesnt seem to be the only one with these problems. And it seems that there is other here in Denmark with absolutely similar problems. Hyundai Denmark is working with the problem, and i surely hope they find a viable solution, so that we can get the full value for this excellent car.
I will report back when i got the new winther tyres mounted.
Forgot: The valve clatter: Got the oil changed - still the same - first when the engine is warmed up - it dissappear...
Thanks for the help so far...

Got Wintertyre mounted Continental TS810 - And now it seems that the problems start all over again... (jumping/wobbling at around 60-75 km/h) Have them dynamically balanced more than once, checked at a specialist - that claimed that the tyres were almost perfect. - much below ordinary tolerances.
Have the car to another specialist-center - and they have the car lifted and each wheel spinned - The left from driving-axel seems to be in unbalance.
Have just got all shiftes in left front - hubs, bearing and driving shaft.
Going to pick up the car in a couple of hours.

Really hope that will help - otherwise i'll want an exchange...
Anyone remeber where they have seen something about the valve clatter, that maybe not is from the valves, rather the power-steering?
Sincerely
A more moderated happy sonata owner...
