NHTSA campaign 16V326000 · announced May 19, 2016 · filed by Daimler Trucks North America Llc · 43 units affected

The problem

Daimler Trucks North America LLC (DTNA) is recalling certain model year 2011-2017 Thomas Built Buses Saf-T-Liner HDX buses manufactured April 28, 2010, to April 15, 2016. 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.

The risk

If the heater hose fails, hot coolant may leak inside the bus body increasing risk of injury to the passengers.

What to do

DTNA will notify owners, and dealers will replace the heater hose, free of charge. DTNA distributed interim notifications 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-709.

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
