2014 Model BMW 320i (F30) Door Handle Erosion

"At the same time, I don't understand why the side skirts of this vehicle, which has the original Harman Kardon amazing sound system as part of the 40th Anniversary package, vibrate so much when the sound is at around 70% due to the bass. The sound inside is incredible, but from the outside, it sounds like a very simple brand's aftermarket sound system, with the side skirts vibrating noisily. How can the insulation be this poor in a BMW vehicle?"

"BMW has still not resolved my request. First, the authorized Borusan service I was in contact with called me and informed me that BMW had acknowledged this fault, and that the two front door handles were in stock. They said that if I wanted, they could first replace the front door handles and that I could make another request later if the rear door handles also wore out. I agreed. However, there was no follow-up from the service afterward. I was told that a written approval from Borusan headquarters was required for the free replacement, but that Customer Relations Manager Ms. Özlem was in a meeting and could not be reached for a response. How is it possible that the customer relations manager is in meetings all day and cannot respond to a customer's request for about 15 days? BMW acknowledges the fault and initially states they will replace it, but then does not respond to the service's emails. This shows how much BMW Turkey values its customers. I am awaiting your prompt and positive response..."
