It really doesn't sound like the system needs to be bled if it functions perfectly in all conditions other than heavy stop and go, followed by a long, high load hill climb.
Sounds like a fan or grille/airflow deficiency with this model.
OP probably did this, but I'd be sure to put the cabin heat on full blast under these conditions until you tire of the car.
