Reviews of OEM KIA brake discs

im on my 2nd set of OEMs but with aftermarket pads. same shit shaking every second day on a highway.

I had same issue with my 2022 kia k5 gtline. It started around 40k kms and took it to the dealership. They told me to replace the front rotors (OEM) and I did. At the time, it seems that the issue is resolved but after 15k kms the damn thing again started to shake. I took it to the dealership and again they told me to replace all the rotors. Fortunately, the front rotors was under warranty because I recently replaced it. I had to pay only for rear rotors and labour. Then after 8k kms this shake again came. And I had enough, I took it to the dealership and told its not the rotors and probably something else. Then one of the technicians told me that because I have a history with damaged rotor twice, they are suspecting me????. Then I told them to do the diagnosis for the rotors which is around 160$(if rotors are fine). Then after the diagnosis they found that the rotor is wearing out faster than usual. And they replaced all the four rotors(OEM) for free of cost. So I guess, its the CHEAP OEM ROTORS from Kia causing all this issue. I will update the results, now its been 1000kms after third replacement of rotor. No issue so far. Now my car is at 80k kms. Never had any issues except this one.
