The short version
Daimler Trucks North America LLC reported a problem with the power train automatic transmission. Here is what owners need to know.
The affected vehicles have a transmission retarder that may increase coolant system pressure high enough to cause hose fatigue and lead to premature failure of the hose, resulting in a coolant leak inside the bus body.
If the heater hose fails, hot coolant may leak inside the bus body increasing risk of injury to the passengers.
