Ducati is recalling the Panigale V4 from model years 2018 and 2019 (including the S and Speciale versions) because of a problem that can cause the oil cooler to leak. The recall affects 1,663 units in the U.S.

According to recall documentation released by the National Highway Traffic Safety Administration, the output port on the oil cooler may crack under extreme conditions, such as in race track usage. Should the port fail, oil can leak from the cooler, increasing the risk of a crash.

The issue was first reported on June 8 after a European dealer noticed oil leaking from a Panigale V4’s oil cooler output port. Ducati immediately opened an investigation. From July to October, Ducati received two more reports of oil leaks. In October, the investigation determined the root cause of the problem and on Nov. 20, Ducati’s internal safety commission determined a worldwide recall was needed.

Ducati dealers will replace the oil cooler on recalled motorcycles with a new one with redesigned oil ports. Panigale V4 models that show signs of oil leakage should not be ridden, but Ducati says models not showing any signs of oil leaks can be ridden to the dealership, but only at low rpms.
