The 2015 Indian Chieftain has 4 recalls, the most serious being a rear brake master cylinder defect and a gear position sensor fault, both of which can cause a crash.
The rear brake master cylinder can lose hydraulic pressure partially or completely, leaving the rear brake with reduced stopping power or none at all, which extends the distance needed to slow down. The gear position switch contacts can oxidize and cause the display to show neutral when the bike is actually in gear, so starting the engine can send the motorcycle lurching forward unexpectedly. On the fire risk side, engine misfires can push unburned fuel through the exhaust system, raising exhaust temperatures to the point where a fire can ignite. There is also an electrical concern involving the vehicle control module connector, which can fail and cut power to the front lighting, including the headlight, leaving the rider without forward illumination at night or in low-visibility conditions.
