How old is the Granite?
First step would be to check all your connections to and from the motor and electronic speed controller (ESC). If those all check out okay you might have a fried ESC. The good news is that it might still be under warranty depending on the age of your Granite.
Sounds like your esc. is damaged, but it's BEC is still working and powers your receiver and servo.
It may sound strange, but your servo could have a faulty electrical circuit which has damaged your esc. It happened to many Arrma trucks before.
So contact your local reseller for warranty!
yes made a spin or two , it did not occur again yetDid you try to run the car again?
If yes, did the problem occur again?
You are the second person with BLS esc. problems. So beside it is an annoyance for you, in general we cannot conclude yet this is an serious issue.
But strange it happens again...it could also be the servo again...
Nevertheless if you want to replace it you have to look for a minimum 40A car esc. for a brushless sensorless motor. Plenty of options and it will not break the bank
