Details
What's wrong: The high voltage battery pack enclosure may not be properly sealed, allowing water to enter the pack.
Why it matters: Water accumulation in the high voltage battery pack can cause a loss of drive power, increasing the risk of a crash.
The fix: The remedy is currently under development. Owner notification letters were mailed April 13, 2023. Second letters will be sent once the remedy is available.
