We purchased (6) 2025 IC School buses and we are having entrance door issues. They are air powered doors and Rush Trucks in Akron cannot get the air regulated to close properly. They turn up the air so that the door closes, the doors then slam very hard that may cause injury if student is close to the door. If the air is turned down, the doors do nut shut properly causing issues with the student crossing lights which then sounds an alarm and the lights do not function properly causing the lights to not activate when crossing students. I have given Rush about a year to rectify the issue but to no avail. Again- This is a student crossing safety concern.
