I have my MS for about 3 months now, and is starting to have some battery problems. My charge cycle is roughly from 30% to 90%, never above the 90% recommended. Recently, I noticed the suggested mileage shown when at 90% starts to drop, from 406km to now 404km. On top of that, as soon as I drive away from charge station, the suggested mileage drops quickly from 404km to 399km in just 500m. Have reported to Service Hotline and waiting for a reply from their technicians. Anyone has experienced similar problems? I start to monitor the actual and suggested mileage since this problem. Currently, the ratio is about 65%. I am not an aggressive driver at all. Is this ratio considered normal?
