The complaint counts, systems and recalls below still stand on their own. The most-reported system is electrical system (225 complaints), typically at 1.3 yr or about 8,000 miles.

The vehicle was charging to 100% and once it reached 81%, jumped to 100% and stopped charging. Two days later, the vehicle populated an error “Battery Management System”. The vehicle was checked in to a dealer and it was confirmed that there was a faulty cell, and the high voltage battery must be replaced.
