BATTERY DEGRADATION, MAINTENANCE COSTS AND RELIABILITY OF A HIGH MILEAGE TESLA MODEL 3 PERFORMANCE

EV Channels Review

This comprehensive review of a high-mileage 2019 Tesla Model 3 Performance (over 103,000 miles) debunks common EV myths. The vehicle, affectionately named 'Clint Beastwood,' demonstrates remarkable durability and reliability. Cosmetically, it holds up well, with minor wear on the front seal being the most notable issue, attributed to the lack of factory mud flaps on early models. Interior wear is minimal, with the steering wheel, seats, and console showing little degradation. Maintenance costs are surprisingly low; aside from standard wear items like tires (£250 each, lasting 15-20k miles), the primary repairs included a seat pad sensor, suspension bushes, and a rear oil pump, totaling under £2,000 excluding consumables. Running costs are also favorable, with an estimated £4,000-£4,500 for 100,000 miles, significantly less than a comparable petrol/diesel car, even with 38% DC fast charging. Battery degradation is minimal, showing 89-90% of its original usable capacity, with a non-linear degradation curve suggesting long-term health. Performance remains exceptional, with 0-60 mph times nearly identical to when new. Depreciation, while substantial (£30,000 over four years), is comparable to performance ICE vehicles. The reviewer concludes that the Model 3 Performance is a highly capable, reliable, and cost-effective EV for high-mileage use, with no intention of selling it.
