2024: “Coming to a stop the engine just quit, as if I turned the ignition switch off. The dash was also blank. I turned the switch to the off position and then back to the on position, and it started as normal. I have read about this same sort of thing happening to numerous other riders of this bike. Triumph needs to have a recall to fix the glitch in the ecu.”
