Equipment Vehicle recall #18V176000 · 2018 · 19 vehicles

What's wrong: The front passenger air bag and recommended child occupant seating positions label May not have been attached during assembly. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (fmvss) number 208, "occupant crash protection."
