Consumer Description

Last week, my vehicle could no longer charge fast and I am unable to charge past 107 miles. The following message appears: BMS_u029 / "Maximum battery charge level reduced" After researching the issue, I found that hundreds of other Tesla drivers have experienced this problem (see: https://teslamotorsclub.com/tmc/forums/model-s-battery-charging.109/). Some were unable to charge after receiving this message, and some were capped at 30-50 miles, making the vehicles practically unusable. Tesla charges $15,000 (remanufactured battery pack) to $25,000 (new) to fix the problem. But many drivers are reporting that the defect is caused by a Tesla design, where the AC condensation drips onto the battery pack and create rust and corrosion, which then cause the batteries to malfunction.
