Affects Nova Bus LFS · 2005–2006 — about 259 vehicles.
The hazard
On certain low-floor buses, the silicone elbow hoses used on the roof-mounted heating system could wear prematurely and burst. As a result, hot engine coolant could leak into the passenger compartment and cause injuries to the passengers. Correction: Dealers will replace the silicone elbows with rigid elbows.
