This Low-Mileage 2025 Tesla Model Y Lost A Lot Of Range Fast

A 2025 Tesla Model Y electric vehicle experienced a significant drop in battery range after 18 months of ownership and approximately 13,000 miles. The owner, who shared their experience on Reddit, reported that Tesla's in-car battery health diagnostic tool indicated a 15% degradation. This level of battery wear was deemed unacceptable by the owner, especially given the relatively low mileage. The owner noted that the vehicle's estimated range, which was initially around 310 miles when new, had fallen to approximately 260 miles. This rapid decline in capacity is a concern for electric vehicle owners, as battery degradation directly impacts the vehicle's usable range and long-term value. The owner is seeking a resolution from Tesla, potentially including a battery replacement, as the degradation exceeds what is typically expected for a vehicle of this age and mileage. Tesla's warranty for the Model Y battery covers degradation to 70% of its original capacity within 8 years or 100,000 miles, whichever comes first, but the owner's experience suggests this threshold might be reached sooner than anticipated for some units.
