So, we took out vehicle to kia for a full clutch replacement on the 18 Sep 2023 , since then issues started to emerge. 1st, my starter motor fell out while driving to work, then our clutch started to squeak and make scratching noise. In total we went back to Kia +/- 4 times because they couldn't fix what ever was/is wrong. On this moment our vehicle is still at kia regarding a scratching noise, and now they want us to pay for a new clutch pedal, which they said they cannot guarantee us is the problem. We are awaiting feedback from Kia SA because i don't want to pay 6K for a 'maby'. I don't know what to do now. Please help.
