2023 Volkswagen Jetta

I have brought my car into my dealership 3 times now for the same problem (a creaking noise in the suspension system) The first time they replaced the parts that I suppose they couldn’t replicate easily see needed replacing, the suspension boot, mounting, and nuts and bolts. For a week I thought the suspension system was fixed then it started creaking (only over speedbumps, and mostly when the weather is colder) again 3 times until it finally stopped. The sound is very situational it happens once or twice a week. If this is what the sound had always been like I would’ve just thought it was normal car functionality but it’s the exact same sound that was cause for repair the first time. I brought it in a second time my service advisor told me they test drive it twice and were unable to replicate the sound so they proceeded to tighten the bolts on the parts they had replaced the first time and gave it back to me. The creaking sound happened 3 more times and I scheduled service once again. This time they practically refused service because 1: I told them it was highly unlikely they could replicate the sound as it only happens on my way over from my apartment complex with 7 speedbumps I have to go over (the creaking would stop after these) and 2: that my warranty for sounds was over and that cars are imperfect machines. Sure but the suspension system makes the same sound that was cause for repair the first time and now it happens on the passenger front side it just happens very occasionally but it is still not a good sound.
