How do we fix many problems: hatch stuck closed, fuel tank on E, service light on

Well, first, fine a technician near you that can help. That's how you fix it. It's not a "do-it-yourself" situation. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops Regarding your specific listed concerns: The fuel gauge could be caused by a problem with the gauge, the sending unit at the fuel pump in the tank or a wiring concern. The Air bag light indicates a problem with the restraint system that simply needs to have troubleshooting performed to find out what's happening. Could be air bags, crash sensors, sliding contact in the steering wheel, inflators, seat belt buckle switches and pretensioners -- so many possibilities here. The cameras - again, needs testing. Calibration? Cleaning? Damage? Impossible to know without testing. Good luck!
