The 2019 Ducati Panigale V4 has 4 recalls, the most serious being a rear wheel axle that can break while riding, causing sudden loss of control, and a fuel cap that can spray fuel when opened, raising the risk of fire.
The rear axle issue is a structural failure: the axle itself can fracture, which removes the connection between the rear wheel and the swingarm and can send the bike into an uncontrolled slide or fall. The fuel cap concern is separate but equally serious on the fire risk front: excessive pressure can build inside the fuel tank and force fuel to spray outward the moment the cap is turned, putting fuel near any nearby ignition source.
Two engine recalls both involve oil leaks that can drop fluid onto hot engine components or the road surface, creating a slip hazard under the rear tire. In one case, the timing chain tensioner can work loose over time and allow oil to seep out around the tensioner adjustment bolt. In the other, a crack in the oil cooler output port lets oil escape more directly. Either leak leaves a trail of oil on the pavement that the rear tire can then pass through, reducing grip without warning.
