I'm hearing about a potenially alarming trend in the used 2012-14 Model S market that refers to these FAQs I put together. https://docs.google.com/document/d/...ouid=101367879314455822316&rtpof=true&sd=true
Specifically, the BMS_u029/018 is a non-specific Tesla alert that is accompanied by “Maximum battery charge level reduced. OK to drive. Schedule service”. In most cases your range is limited to around 60 miles and usually requires full pack replacement.
One solution has been resetting these alerts at the fraction of the cost of a replacement pack. This less expensive option can be utilized by both dealers and owners looking to sell. Then the vehicle is sold, undisclosed, to unsuspecting buyers. These alerts will then likely return with any software upgrade - MCU2 upgrade, OTA upgrade, etc. - or just over time.
Unfortunately the new owner has inherited these alerts and new significant burden.
Possible solutions - Tesla and other 3rd party vendors have to ability to see if these alerts were reset or you could get the seller to state in writing addressing any BMS_u029/018 resets.
