KIA Motors review: rear absorber

Model Kia Sportage 2.0, Reg No BNB 6826, Chassis No KNAPC81ASF7683581 &
Engine No: G4NAEH810315
My rear absorber sound is getting significant. I've logged the complaint ever since day 1 during the second time of service. Even up to 3rd to 5th time of compliant but no action has been done. Now it cost me to few thousand buck for replacement.
Been a Kia supporter for so long, I really hope this complaint could trigger professional judgement to be carrier out. I can be reached [protected]@uns.com.my.
