GEN 3 starting issues

[Bumblebee]

The nightmare returns! After three perfect months, yesterday I had another problem turning on at the traffic lights and not even too hot! Started after 5 minutes and never did it again. I had changed the starter motor and gears. I'm desperate, even out of warranty

That would be most frustrating......I'm sad to hear this...

Had this issue on gen 2 everytime with hot start. My guess it is something to do with internal of the engine expanded due to heat so i changed battery to Lithium with higher output. Never had hot start issue again for the next 5 years of ownership.
