Blue Bird is recalling more than 2,500 All American school buses and some transit buses to fix a problem that could make steering more difficult.
The company also is recalling a smaller number of school buses that may be prone to a propane fuel leak.
It says it has received no injury or accident reports tied to any of these recalls.
Blue Bird Corp. says the steering problem can develop on some buses made between 2011 and last May if a steering shaft clamp comes into contact with a rubber close out boot on the floor. It also is recalling more than 400 transit buses to fix the same problem.
The company also is recalling 388 Vision school buses made in 2012 or 2013 to address the possible fuel leak.
