Had issue similar to many, service charging system error occurred in esave with max regen engaged, car had a complete loss of power, indicator on gear shift flashed D. Able to restart and get to dealer, where they ran the RRTs. In the 5 miles they drove it they could not recreate the error so, in their mind it does not exist. Per service advisor they checked the battery harness even though that was just a yes yes when asked and not volunteered. Less than 24 hours in their possession I’ve been asked to pick it up and begin driving it again with zero explanation for the cause….. guessing it was because I’m female and they think I’m an idiot……
