Mitsubishi Space Star Brake Discs Worn Out Prematurely – No Response from Customer Service

I purchased my 2021 Mitsubishi Space Star from an authorized dealership and have diligently ensured all maintenance, including brake disc replacements, was done at the official service center. Yet, only 7,000–8,000 km after replacing the discs and brake pads, I was informed during the latest service that they are already worn out and need replacement again. I contacted Mitsubishi customer service about this but received no response. This car has become a constant expense, despite my efforts to follow the official maintenance protocols. If I’m using the authorized service, Mitsubishi should take responsibility and address my concerns. It’s disappointing to feel ignored, and I'm beginning to regret choosing this brand.
