What are the known high-voltage battery defects in the 2020-2022 Audi e-tron S and e-tron S Sportback?
The LG E61V battery cell modules can develop voltage losses, causing reduced range, power limitation, and in extreme cases thermal runaway or fire. Audi issued recalls 93U9/93V2 and NHTSA 23V867 covering 2018-2022 model years, with interim guidance to limit charging to 80%. The repair is free under recall, but out-of-coverage module replacement would be far more expensive.
