Spoke with Cobalt service tech for my region. She indicated that they normally relocate the fire extinguisher on the starboard side which I said is a problem when trying to access the battery or drive fluid reservoir. She will follow-up with someone in engineering to see if the fire extinguisher can be mounted via shims over the reinforcement plates (the ones they add to strengthen the ski pylon). She will also follow-up with my dealer.
Too bad the service tech needs to speak to engineering who needs to speak with someone else etc. It would be nice to have spoken to a person who knows.
Next update will be when I hear back from either cobalt or my dealer.
