Current mileage is 35,000km.
Loud wind noise and road noise after reaches 20,000km at speed 100km and above. Noise tend to reduce comfort and driving pleasure.
Manufacturer/service still cannot solve the problem.
Car handles good in wet/rain and twisted road conditions.. thanks to its TCS.
You need to add sound insulator. (They did not install any.)
Trust me man.
I have the 2004 EF Sonata 2.4L.
Noticed of the noise.
Hence you need to invest around MYR2000-4000 to get the insulator.
You can send to GS (hyundai panel opp Kah Bintang PJ 222).
Best of luck.
