With the rising cost of gasoline these days, I was considering the purchase of a locking fuel door to deter someone from siphoning gas. They are functional and look good. A friend is a Dodge mechanic and he tells me the Ram pickups have a device to prevent gas from leaking during a rollover that also prevents siphoning. Does anyone know if the Canyon has this feature? If it does, then the locking fuel door is strickly an cosmetic addition.
