I can understand people wanting to get BRP involved with the fires, and their wish find the cause(s) and cure(s), but in reality, the key to getting the Spyders repaired or replaced lies with the insurance companies. In fact, if anyone has enough clout to get BRP involved, it would be the insurance companies or the NHTSA. These incidents need to be reported to both...ASAP, after an incident. I would not expect warranty repairs or replacement, as some seem to be relying on. I'm not sure why BRP Customer Support would be first in line...or in line at all, unless dragged.
There have been at least two types of problems which did or could have readily contributed to fires. Some are convinced that the short emissions canister vent on the original GS Spyders contributes to fires in some way. That is entirely feasible. If owners have not had the "second update" completed and the canister vent extended, I urge them to do so, and eliminate this possible cause.
Others have had fuel leakage from the fuel filter, either from loose hoses or a split filter. There is no evidence linking this directly to fires, but it is certainly a possibility. This is more difficult to head off, especially on a vehicle as fully enclosed as this one. I urge all owners to carefully inspect the fuel filter at regular intervals, at least every oil change. Look for leakage when running, and for loose clamps. The gap to the filter is not really important, but the hoses should not be able to be slid or twisted on the filter. If so, either the clamps, or the clamps and hoses, should be replaced. While you are at it, make sure the fuel hose is not rubbing against the engine, and is protected where it passes the head, by a corrugated tube. Early Spyders had some interference and wear problems in the area of the front head.
Again, my sincere sympathy to those who have suffered through these incidents. Please report them to the NHTSA and then let your insurance companies take over. The idea is to get you back on the road as soon, and as safely, as possible. All the customer support in the world can't help much there. It takes good insurance and a good dealer.
