What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Plastic gas tank has expanded and warped, causing tank vents to stop working effectively. Gasoline now leaks and sprays extensively from the top of the tank, covering the tank and surrounding areas with gasoline. Gasoline also leaks extensively from the overflow tube onto my garage floor.
My motorcycle is now dangerously defective, a fire hazard, not suitable for use and would fail a safety inspection making it unlawful to operate on hawaii roads.
After several tank replacement by ducati the problem persists. Tank keeps swelling and puts stress on the latch so that it can't be unlatch to get to the battery or for service . Tank also doesn't sit firm on frame at pik swelling time . Tank also leaks fuel at bottom around seal while swelling is at max.
Swelling fuel tank is creating an unsafe condition where tank may split resulting in failure, fire, or other hazard. Swollen tank is also pressing against other systems and could cause failure to start, failure or front wheel to turn completely, failure of seat locking mechanism to completely engage.
The expansion of the tank can cause a leak of the gasoline causing not only a damaging effect on the environment but also a serious risk of fire and injury to me. Also the tank can cause pressure to the rear seat latch causing it to pop off during riding thus causing a crash and injury.
I have made no modifications to the fuel tank or fuel pump. I took the bike to the dealer who submitted a claim to ducati north america (the importer/factory). To date, I have not heard back about the claim. I am very concerned as to the safety of this motorcycle now.
