La présente a pour but de vous informer que votre véhicule est susceptible d’avoir un défaut qui pourrait porter atteinte à la sécurité humaine. Cummins procède à un rappel concernant certains moteurs Cummins X12 fabriqués entre le 26 avril 2016 et le 1er novembre 2021 destinés à être installés sur des mélangeurs, des camions, des autocars, des véhicules d’urgence, des camions à ordures, des véhicules récréatifs et des grues. Le présent avis s’applique aux moteurs ou véhicules figurant dans le tableau ci-joint. QUEL EST LE PROBLÈME? Les tubes de carburant entre la rampe de carburant et les injecteurs des cylindres numéro 4, 5 et 6 peuvent se fissurer, entraînant une fuite de carburant à haute pression. Une fuite de carburant à haute pression qui entre en contact avec une source d’allumage représente un risque de feu. QUELLE SERA LA RÉPONSE DE CUMMINS? Cummins travaille actuellement à mettre au point une solution permanente à ce problème. Vous recevrez un deuxième avis qui vous indiquera le moment où une solution définitive sera offerte et qui vous donnera aussi des instructions pour procéder au rappel de votre moteur. QUE DEVEZ-VOUS FAIRE ? Cummins vous recommande d’effectuer une vérification périodique des tubes d’alimentation des injecteurs afin d’y déceler tout signe de fuite et pour pouvoir effectuer les réparations nécessaires, le cas échéant. Si des fuites surviennent, il est possible que l’opérateur perçoive l’odeur de carburant diesel ou qu’il observe une vapeur de carburant. Les ailleurs de véhicules qui reçoivent le présent avis de rappel doivent en faire suivre une copie aux locataires, ainsi qu’une copie de tout avis subséquent, dans un délai de dix (10) jours.
