Example complaints
Engine cooling: “Vehicle stalls when attempting to accelerate normally (typically stalls in intersection). Not frequent. Vehicle restarts normally. Occurs when engine is fully warmed up.”
NHTSA complaint #10223529, filed 2008-04, 3,000 milesElectrical system: “I had a new 2005 majesty (Yamaha) scooter. It would on occasion stall. I had it twice stall while merging onto the freeway. This almost resulted in a crash, but I was able to get to the shoulder and restart the engine. The dealer replaced the ecu and I have not any problems since.”
NHTSA complaint #10224148, filed 2008-04, 320 milesEngine: “Once engine was warmed up, vehicle stalled at stoplights twice and once when starting to move after a stop (when in an intersection). Other times when stopped. Idle speed dropped below 1400, under which it stalls, and it was difficult to rev the engine to prevent stalling since there is no neutral gear, so revving more than slightly can make the vehicle move.”

100% of the 6 complaints with a mileage were filed for vehicles with under 50,000 miles; the middle half falls between 3,000 and 12,100 miles.
