New Opel Grandland Shows Multiple Faults at Delivery

I was invited by Çetaş, located in İzmit / Kocaeli, to take delivery of an Opel Grandland 1.2 Hybrid 145 e-DCT6 GS+ Ultimate package vehicle on December 10, 2025. However, during the vehicle presentation in front of the dealership, I noticed several serious issues while the car was being shown by the staff. These included a “Collision Brake System Malfunction” warning light on the instrument panel, a rear left taillight malfunction warning, improper closing of the driver’s door, and vibration, shaking, and unstable idle while the vehicle was running. Because of these problems, I clearly stated that I would not accept delivery of the vehicle in this condition. I informed the sales manager Mr. O* and sales consultant Ms. E* about the situation. I was told that the battery was weak and that the issues would resolve during driving, and based on this explanation, I left the dealership. Approximately 15 minutes later, I called back to report that the problem persisted and formally requested a replacement vehicle. As a result, I delivered the car to the authorized service on December 10, 2025. The authorized service staff stated that the vehicle would be put into sleep mode and that the issues would resolve, a process that took three days, but no solution was achieved. They informed me that the situation had been reported to the factory and that they were awaiting feedback. Later, they removed the rear taillights from another test vehicle of the same model and installed them on my vehicle to attempt a solution through trial and error. For the vibration issue, they performed a software update, stating that the system had not been up to date. Regarding the driver’s door issue, they left the decision entirely to me, explaining that if they intervened, the door adjustment would be recorded as a disassembly/reassembly process by appraisal companies. Despite my repeated requests for a replacement vehicle, I was told each time that this was not possible. For the collision brake system malfunction warning, they stated that ordering and replacing the part with an original one would solve the issue and informed me that a parts order was opened on December 22, 2025. Even though I stated that I did not accept this and requested a replacement, they insisted that only a part replacement was possible. At my request, I was provided with a replacement vehicle on December 12, 2025. As a result of this entire process, despite having paid the full price in advance as a consumer, I was delivered a defective and faulty product, left without a proper solution, and denied a replacement with an equivalent vehicle. Because my vehicle was not replaced during this period, I have been left in a situation of serious consumer hardship.
