Have you checked the 12V battery. I had to replace mine on my Kona. Won't start if the 12V is deadGoes into derate, top speed 60k. Shuts off at times not sure if it will restart. I will keep you post on the bill and what it was. The earliest he could get in is may 29 in vancouver. Then he has to fly down and drive it home. Not sure when it will be fixed. But i will keep you posted.
