NHTSA's recall notice

Defect description
Prevost Cars, Inc.(Prevost) is recalling certain model year 2009-2011 XL2, XL2 Shells, X3 Shell Converted Coaches, and X3 motorcoaches manufactured January 1, 2009, to December 31, 2011, and equipped with an automatic fire suppression system (AFSS) pressure tank in the engine compartment. The tank's pressure relief valve may not withstand the temperatures in the engine compartment, resulting in the venting of the extinguishing agent.

A second notice for owners to obtain the remedy was mailed on May 21, 2015. Owners may contact Prevost customer service at 1-877-773-8678. Prevost's number for this recall is SR15-01.
