2024 Flash - heat pump noise/vibration?

[WildBlue]

Now that the cold has arrived, I have noticed that I can hear and feel a vibration from under the frunk area when demanding cabin heating. This was not something I noticed on my 2023 XLT ER, so I assume it's coming from the heat pump. Seems fairly noisy to me, but wondered what others thought about theirs.

Looking forward for heating performance reports from the model year 2024 Lightning owners!

My initial thoughts given the current temperatures is that the heat pump isn't making much difference right now. Temps are in the low 40s currently, but will get cooler as we approach winter.

I've noticed similar noises on cool mornings and guessed that the heat pump was making them. Haven't had time to poke around and verify the guilty party.

Will plan to report on heating performance after we've had a few weeks of what passes for Winter around here. 47°F this morning, so we locals are getting out the down jackets.

I think the more important reports will come from folks who experience real winter. It's easy for heat pumps to work efficiently when it's mildly cool outside, but when it's actually cold, heat pumps have a harder time. Does anybody know if our trucks have backup resistive heaters?

I don't know if lightnings have backup resistive heat but teslas don't. they use the motors to run inefficiently and the heat pump scavenges the excess heat which acts as a substitute for resistive heat backup. maybe ford did the same thing?

I've been noticing some noise when slowly starting off when the heat is on. I wouldn't call it vibration exactly, it seems almost like a low gear hold (in ICE terms). It seems to go away when getting moving a little faster, but not sure if it's just overcome by wind/tire noise.

I haven't gotten out of the truck and listened around the frunk though, so not sure where it's coming from. Maybe I'll do some listening this weekend.

Good morning, if you send us a message with your VIN and mileage, I would be happy to take a look into your noise concerns.

So far I have had temperatures in the 20s and have used the heat pump feature in my 24 lariat extended range. It is so far doing exactly what it supposed to do.! haven’t really tried to compare it as far as efficiency.
