Toyota Corolla Steering Wheel Deformation

I own a 5‑year‑old Toyota Corolla with 50,000 km and a remaining 7‑year warranty. Despite this, the steering wheel on my vehicle is visibly worn and deformed, which I do not consider normal for its age and mileage. About two weeks ago, I took my vehicle to the Bursa Toyota Çavdarlı authorized service center regarding this issue. Although I clearly stated that the vehicle has a 7‑year warranty and is only 5 years old, I was told the steering wheel is out of warranty and that they would not take any action. I have always had all maintenance and previous work performed at authorized Toyota service centers, and I find it unacceptable that this wear issue is not covered under the warranty. I request that the steering wheel on my vehicle be replaced at no charge under warranty, and that this unjust refusal by the service be reviewed and corrected. I expect Toyota to honor its 7‑year warranty and resolve this issue as soon as possible.
