- Summary
- Daimler Trucks North America LLC (DTNA) is recalling certain model year 2014-2017 Thomas Built Buses Saf-T-Liner HDX school buses manufactured November 29, 2012, to February 4, 2016. These vehicles use a rubber elbow to connect a coolant line to a heater inside the bus. This elbow may restrict coolant flow and possibly fail as a result of the increased stress on the elbow.
- Consequence
- If the rubber elbow fails, hot coolant may leak inside the bus body increasing risk of injury to the passengers.
- Remedy
- DTNA will notify owners, and dealers will replace the rubber elbow with a nylon fitting, free of charge. An interim notice was sent out to owners on July 6, 2016. The recall began on September 20, 2016. Owners may contact DTNA customer service at 1-800-547-0712. DTNA's number for this recall is FL-708.

Has your Thomas Built Buses been repaired?
Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.
NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Thomas Built Buses dealer can also check your VIN. Recall repairs are free.
