My Tesla 90D has steadily losing range for an year now. At 80% charge I used to get 224 miles and now its reduced to 214 miles. I did a long trip where the battery was depleted twice below 10 miles and we supercharged it to 100% thrice. Not sure if this could be a reason. I asked Tesla to check the batteries but they are asking $500 for inspection. They will refund if the battery has a problem. Anybody had experience with similar situation, is this normal degradation?
