Brand New Peugeot E-3008 Battery Health Issue

I have a Peugeot e-3008 Allure model vehicle, registered on January 20, 2025, which I purchased in Turkey. Due to concerns about range and battery usage during the first few months of use, I delivered my vehicle to General Oto Peugeot authorized service on May 22, 2025. I received it back on May 27, 2025, but was not given detailed information about the battery’s health. I was simply told there was no issue and advised to drive 500 km and return. Following their instructions, I brought the vehicle back on June 21, 2025, with the same complaint. This time, it was determined that the battery health had dropped to 80%. A file was opened with Peugeot France, but they closed the case by declaring this situation normal, without even allowing the local authorized service to respond. My vehicle is only 5 months old with just 6,000 kilometers of usage, yet Peugeot deems it acceptable that a nearly new vehicle has lost 20% of its battery capacity. This means I cannot use 20% of the promised range, which is a significant and unacceptable loss. For instance, if a standard e-3008 can travel 450 km under normal conditions, my vehicle can only reach 360 km; or if another can go 400 km, mine only manages 320 km. Such performance loss in a 4–5-month-old car is absolutely not normal and qualifies the vehicle as defective. The 80% battery health reading is documented by General Oto Peugeot. I am formally requesting that PEUGEOT TURKEY and/or PEUGEOT FRANCE urgently offer one of the following solutions: (1) replacement of the battery with a new one to restore full usage capacity, (2) replacement of the vehicle with a new one of the same model, or (3) return of the vehicle and a full refund based on the current list price.
