Citroen C5 Aircross Transmission Problem Unresolved After Warranty Repairs

I own a 2026 model Citroen C5 Aircross with only 15,000 kilometers on it, and I have been experiencing a transmission problem since September 2, 2026. Despite the vehicle being almost new, such a serious malfunction has occurred in a very short period of use. On September 3, 2026, I left my vehicle at the Konya Özkaymak authorized service center under warranty. Since then, I have repeatedly taken the vehicle to the authorized service, but the transmission problem has still not been resolved and the malfunction continues. During this period, I was not given clear, consistent or satisfactory information about either the cause of the problem or the repair process. My vehicle has remained in service for a long time, yet I have not been provided with a replacement vehicle, and I have been left without a car for about a month, which has caused me serious grievances in my daily life and work. I find it unacceptable that a nearly new vehicle experiences such a transmission fault and that no definitive solution is offered despite being under warranty and repeatedly brought to the authorized service. I request that the transmission problem on my vehicle be permanently resolved under warranty without any cost to me, that my vehicle be returned to me as soon as possible in perfect and safe working condition, and that my losses and grievances caused by being without a vehicle during this period be compensated.
