NHTSA Complaint #11710502 — 2015 CHEVROLET SPARK

INCIDENT SUMMARY In February 2025, while driving on the freeway, my vehicle experienced a sudden and complete loss of power. The battery rapidly depleted without warning, causing the vehicle to decelerate dangerously in moving traffic. A Stabilitrak warning appeared on the display.
