Opel Grandland X Peeling Steering Wheel and Warranty Denial

I have a 2020 Grandland X with 51,000 kilometers on it. I bought it because I trusted German-made cars, but it turned out to be worse than Chinese cars. The most recent problem I've had is the peeling of the steering wheel. Openings in the interior column, noises from the door handles, roof creaking, oil leakage from the engine hood, and a faulty starter motor are among the other issues I've encountered. I've owned cars before, but this is the first time I've noticed peeling on the steering wheel of a three-year-old vehicle. The standard warranty expired in May, but I extended it for another two years after purchasing the vehicle. I contacted Opel Alpata service, but they were unhelpful. When I contacted Opel headquarters, they both stated that it's normal wear and tear and that there's nothing they can do about it. I'm a member of Grandland social media groups, where many others have had the same problem and had it covered under warranty. I condemn Opel Turkey's double standards.
