getting malfunction on message, vehicle is bouncing when I hit even small bumps in road. hear air escaping from driver's side of car

Suggest you not drive very far with the air leak. This could burn out your compressor. Airmatic leaks are a common failure. Dealers and some indy shops can easily repair. There are also good instructions on GL forums if you want to fix it yourself. Arnott makes compatible parts for the airmatic system and they have a lifetime warranty.
