Le démarreur rsw22 avec étanchéité renforcée à l'eau (rwt) peut subir une abrasion accrue du contact magnétique, provoquant l'accumulation de dépôts au point le plus bas à l'intérieur du relais. ces dépôts peuvent augmenter la résistance de contact du relais, entraînant des défaillances de démarrage ou des courts-circuits. si un court-circuit se produit, soit lors de la tentative de démarrage du véhicule, soit lors de la conduite en raison d'un mouvement des dépôts lié aux vibrations, il pourrait provoquer un événement thermique et augmenter le risque d'incendie.
