CONDITION
During vehicle inspections, when the vehicle under covers are removed, debris is found on the
undercover near the end of the hydrogen tank. Upon closer inspection the debris is found to be
coming from the end protector of the tank.
RECOMMENDATIONS
During vehicle use heat and ultraviolet light can cause degradation of the tank protector causing the
foam to come off.
This protector is added by the supplier to protect the tank during the production process, this does not
negatively affect the tank and is only an appearance concern.
It is recommended to clean the undercovers before reinstalling. No repairs are recommended.
