Valve timing control (vtc) actuator is defective and can cause catastrophic engine failure. The issue manifests itself as an occassional innocuous rattle at cold-start (after sitting overnight). American Honda has issued service bulletin 16-088 (February 2017) to address defective variable valve timing control (vtc) actuators on the 2015 Honda Fit (https://testing-public. Carmd.

It is unsettling that Honda is not being proactive in addressing this issue before an exploding eying causes harm.
