It was during highway driving, the check engine light suddenly turned on. Power was down.

Brought it to the casa, they found that cylinder 2 was misfiring. It turned out part of the piston was broken off. Sh***y luck.

Car is still under warranty. Its only 1 year and 8 months old. The engine will be sent back to the factory to be studied according to the casa. They might even issue a recall.
