NHTSA Complaint #11573072 — 2011 MERCEDES-BENZ C300

The sam box (electrical system fuze panel) located under the hood is in a spot where if the lid isn't on correctly water will drain from the windshield right into the sam box and cause the vehicles electrical system to deploy the steering wheel airbag. That's at least what happened to me. It was raining out that day and I guess I went over a bump that caused the lid of the sam to get out of place. I drove home and the car seat for a few hours. I went out upon unlocking the door as soon as I pulled the handle to open the driver side door the steering wheel airbag blew and the vehicle is now in srs mode. The dealership had told me that it's a design flaw but wants me to pay for the diagnostic. No lights were on and I did not file a police report.
