Fan turning on all the time

[Proyota]

Anyone experiencing their fan turning on all the time? Mine cycles on and off constantly, even in temps as low as the mid-30's and after pulling off the road after a mellow drive. It stays on for maybe 20 seconds and shuts off and then will turn on again a minute later. Is this cause for concern, or just the way it is?

Ive never heard mine turn on at all.... weird

I noticed some fan noise from the back, probably from the traction battery, yesterday inside my garage. the car was sitting for a good 4 hours.

Mine does that when the HVAC is on... fan cycles on and off (30 seconds or so on.... 10 or so seconds off). If I turn off the HVAC completely it doesn't cycle (or come on at all).

I am not sure if that is a feature (cycles for energy saving) or a bug (something funky is going on).

The HVAC runs off the traction battery, which has it's own separate under-hood cooling system. My guess that is what you are hearing, at least that's what I hear when waiting in the pick-up line at G-Baby's school.

Thank you for the replies. I will try turning off the HVAC system next time I drive my truck.

I’ve been hunting a lot lately, driving through the woods at 5-10 mph. I hear the fan kicking on and off all the time as well.
