exhaust mode failure

[Gils4433]

so just got the car and on the way home i get a prompt "exhaust mode not available" followed by " driving mode not available"...essentially can't go to sport exhaust or switch driving modes. Next day problem gone...3 days later it's back...seems intermittent...any idea?? exhaust bypass valves getting stuck?? system glitch? dealer said they will probably flash the computer...also have my airbag indicator light on most of the time...what's with these gremlins??? love the car though, handles amazing, looks stellar, sound is EPIC!!!

Re-plug the exhaust valve connectors. Some people have reported them being loose and causing this problem. If not, one of the motors or sensors may be defective.

Airbag light, I have no idea, maybe it is computer related then.

I've had my drive modes fail on me twice during autocross and its never happened again. Boht times happened during a super hard turn. I checked my valve connections as well. I can't believe how many dependencies are tied into the valves functioning. It's not just an instruction receiver.
