<p>Yes, I can confirm I've had one experience of the Leaf switching to Neutral while driving, with a yellow warning symbol on the dash. It refused to reselect Drive until I had switched the car off and back on. Derek wasn't so lucky and he need to clear fault codes before the car would work.</p>
<p>On returning home, I found OVMS was not accessible over a network. I didn't try a USB cable. Unplugging and reinserting the OBD cable caused OVMS to rejoin Wi-Fi. However the SD logs showed nothing from the time of the event. CAN writes are enabled, so it can perform SOC limiting.</p>
<p>My car has been using this firmware since 21st November, based on the git master of that day. As a relatively new user of OVMS (only since October) I don't have much experience of older firmware.</p>
<p>Perhaps a safeguard should be implemented before releasing a new stable firmware that will be automatically downloaded by Leaf owners. But I don't have the expertise to know what that safeguard should be. Derek's suggestion of 'only CAN write when parked' appears to be a good idea.</p>

<div dir="auto">I haven't ruled out it being a fault with my car yet. Shortly after it faulted the car was run into so has been off the road for sometime, my first step was to replace 12V battery. The ovms unit is now unplugged and if it does not fault over the next month while driving I'll be reasonably confident it's ovms related.</div>

<div dir="auto">Not sure which firmware version the poller updates were included in but it was only after upgrading to it that the errors occurred (which could be coincidental however it has faulted twice more both on version 3.3.004-141-gf729d82c). For periods where I reverted to 3.3.003 it was fine.</div>
