Began driving on to highway. Between the shift from 3rd to 4th gear, the clutch pedal depletes completely and does not return. After towing the car to a dealership, we find the firewall is broken. When a new firewall was put in it was noticed that the part of the firewall was modified and reinforced. I still have the old part to show proof of the change made.
