Question:

If I add a luggage carrier or sunroof to the roof of my vehicle, will it keep the roof-mounted side impact airbags from working properly?

Answer:

As long as the luggage carrier or sunroof is properly installed so that the vehicle's basic structure is not changed, it is not likely to keep the roof-mounted side impact airbags from working properly in a crash.
