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.
