2024 Opel Corsa Automatic Gearbox Fault Persists Despite Repeated Warranty Repairs

I purchased a 2024 Opel Corsa 1.2 turbo full automatic vehicle in 2024, and my car is still under warranty. Despite this, I have been experiencing persistent transmission-related faults, and the problem has not been permanently fixed for a long time. The first fault occurred on 3 October 2024. My vehicle displayed a gearbox fault warning, and I first took it to the Topkapı Odak service. After keeping the vehicle in service for a few days, they informed me that a software update had been performed and that the fault was resolved, and the vehicle was delivered back to me. Finally, because it was close to my home, I left the vehicle at Haramidere Erdemir service on 8 December. The vehicle was delivered to me again on 15 December, with the information that the problem had been resolved. On 16 December, the same fault reappeared, and I took the vehicle back to the service on the same day. On 20 December, the vehicle was again delivered to me as if it had been repaired, but unfortunately, the same fault occurred again in less than half an hour. My vehicle plate number is 34-KHZ 798. During this whole process, I called Opel Turkey many times, but unfortunately, no concrete solution was offered, and I did not receive any effective support. My impression is that Opel Turkey and the services are only trying to get rid of the situation instead of solving the issue. Even though I called Opel Turkey again two days ago, I still have not received any feedback. I clearly see that customer satisfaction is at zero for Opel. I am also wondering whether my car is not being properly repaired because it is still under warranty, and whether they are planning to charge me for the same repair after the warranty expires, which further increases my uneasiness and loss of trust. Despite repeatedly taking my under-warranty vehicle to authorized services, the gearbox-related warning and malfunction have not been permanently resolved, and I have lost my trust in both the vehicle and the service processes. I request that this chronic fault be permanently eliminated as soon as possible, and if a definitive solution cannot be provided, that my vehicle be replaced with a new one or that a solution that will not victimise me be offered. If my problem is still not resolved, I will seek my rights through legal means and I am considering taking legal action against Opel Turkey as well as the Cevizlibağ Odak and Haramidere Erdemir services.
