On certain buses equipped with Detroit Diesel series 50 engines, the turbocharger can fail, allowing lubricating oil to enter the exhaust system. This can result in an engine compartment fire, possibly resulting in personal injuries. Correction: Dealers will install an exhaust temperature sensor and reprogram the Electronic Control Module (ECM). Note: Upon further investigation, Detroit Diesel determined that Prevost coaches do not use a catalytic converter and therefore aren't affected by this problem.
