I currently drive a 2004 z4 smg and have many problems. Does anyone drive an smg that has had any problems?

Could you be a litttle bit more specific concerning the problems?
Thanks, Welcome to the forum.

when its up hill.... it jumps than the car goes.... or when its in automatic and im on the freeway its in gear 6.... i end up in a traffic and i have to press the gas peddle all the way down until it changes into gear 4.... i went to go fix my passenger air bag.. they fixed it but the light still turns on....

I don't think the air bag has anything to do with it.
When going uphill, is that also in automatic mode?
Otherwise, it sounds like "normal" automatic behavior; it will only downshift if you brake suddenly or accelerate suddenly to affect a large change in torque. If you're in traffic and want to keep good mpg, it is best to keep it in a manual mode and shift it as you like. Automatics are notoriously fidgety (unless CVT) for unpredictable, traffic-laden driving; even though it is easy for the driver the transmission gets confused.
