Recall 10V168000: 2009–2010 Trans Tech DW4+9139, 2009–2010 Trans Tech DW5139, 2009–2010 Trans Tech DW5193FRL +10 more

The problem

Transportation collaborative inc. (tci) is recalling certain model year 2009 and 2010 school buses models sst 30 pak, sth4+9, sth4, sth5rl, st5, st4, dw4+9139, dw5193frl, dw5139, dw5+9195, dw5+9159frl, dw6159frl, and dw6159 manufactured on chevrolet express and gmc savana chassis from february 2009 through april 15, 2010. The hvac control knobs may fracture and spin on the control shaft causing the operator to be unable to control the defrost system. These buses fail to conform to the requirements of federal motor vehicle safety standard no. 103, "windsheild defrosting and defogging system."

The risk

If this condition affects the defrost system when it is required, it may decrease the driver's visibility, possibily resulting in a crash.

The fix

Tci will notify owners and dealers will repair the buses free of charge. The safety recall began on april 29, 2010. Owner may contact tci at 1-845-988-0419.
