15 RT Brake/airbag Problem

Hey guys, I have a 2015 rt shaker with about 2500 miles on it that I got about 3 months ago. For the last week, I've had the service airbag system come on and off randomly during operation. I've tried pulling the fuse, checking connections, ect and nothing has fixed it. Two days ago I was driving normally and the ABS light and stability control lights came on and turned off, 30 seconds later when coming to an intersection I went to Brake and had no pedal response and very strong vibrations in the pedal. I got the brakes to work after pumping them several times and immediately parked the car and had it towed to the dealer. The dealer attempted to pull codes and told me that nothing came up (a load of bs) and then told me that they pulled 2 codes I've never heard of/don't think exist. Has anyone ever heard of the codes: C003902 or P3A2F68?

Also, any ideas what could be wrong with the car? I'm thinking the seal on the master cylinder is starting to go and there's a problem with a sensor in the airbag system somewhere. Could a master cylinder set off the stability control light as well though?

Thanks in advance.
