What's wrong?
The exhaust flex pipe on the 2007 Nova Bus Nova Lfs is the section of exhaust tubing between the turbocharger and the diesel particulate filter. It lets the exhaust system move with engine vibration while carrying hot exhaust gases into the filter, where soot is trapped before the gases continue through the exhaust system. A band clamp holds that flex pipe connection in place.
On affected buses, the band clamp was installed in the wrong position. That leaves the flex pipe connection without the clamping force it needs, so hot exhaust gases can escape at the joint instead of staying inside the exhaust path. Those gases can be directed onto nearby components that were not meant to take that heat.
There is no warning sign before failure. An owner, driver, or maintenance technician should not expect a specific sound, light, or dashboard message before the exhaust leak starts.

What happens at the repair
At the dealer, a Nova Bus technician checks the flex pipe clamp between the turbocharger and the diesel particulate filter, then positions the clamp correctly so the exhaust pipe is secured as intended. Nova Bus has already notified owners, and the recall repair is free of charge. Parts and labor are covered under campaign 15V073. This work addresses the clamp location described in the recall and does not require an owner-paid repair.
