2019 Ski-Doo 600 ACE Won't Start - Known Defect - Intermittent

My 2019 Ski-Doo Renegade Sport (Orange Crush) intermittently refused to start. The system electronics would boot up but the engine (600 ACE) would sometimes not turn over.

Stranded out on the frozen lake, I was about get the UTV to tow the sled home when the starter decided to work again.

At the Ski-Doo dealership, the machine started fine (as expected!). The service manager suggested this was user error - that I hadn't waited for the complete boot-up sequence before trying to turn the engine over to start it.

That was not the case. The mechanic  discovered there's a known issue with the throttles on 600 and 900 ACE engines.

Apparently the throttle misreports that it is wide open. The onboard computer refuses to start the engine under the assumption that the engine would race, become a hazard, and destroy itself.

The dealership replaced the throttle assembly (BRP part 512061256) under warranty.
