You might try removing the bottom cover in the frunk and measure the temperature after a drive. I've noticed that lower area gets fairly warm since it has an open drain to the area below - the components below give off a fair amount of heat.

Sounds like a great OTA. Hope this actually rolls out. We've become skeptical because there have been a lot of feature announcements without actual rollout (for example, Blue Cruise 1.1, 1.2, 1.3, 1.4, 1.5).

Ok, is no one asking about this little item? Which update added this? Have a 2022 and have been missing having this useful piece of info when charging.

Great idea! Thanks!

It's working on Android too. You need Carscanner installed on your phone, then look for the Carscanner app in your list of Android apps on your truck's screen. All the above mentioned bluetooth obd readers should work. I'm using this one...

If you've already tried disconnecting and reconnecting the 12V battery and still seeing problems, then it sounds like it's time for a dealer visit to correct it. The displays are pretty vital for operating the truck, so I'm sure they'll prioritize fixing yours.

Last update was ECG-24.2.5.6.1 about 2 weeks ago.

Oddly enough, my dashboard screen went totally dark today. The big center console screen was still working in my case. I tried a soft reset (hold down left and right outer buttons on steering wheel) and it didn't help. Tried turning off the truck and restart, also no good. So I opened the...

Sounds like a fun trip! Hope you guys have a great time. Range is going to drop 10%-30% in colder weather. I'd charge to 100% overnight and set it to pre-condition before the departure time to maximize range. Even then, I'd stop for 10-15min to top up and stretch my legs or use the bathroom or...

As @RocketGhost rightly pointed out, the cooling system is a combination of an AC loop with refrigerant and a liquid coolant loop through the battery and motors. What we're seeing is that overheating during fast charging can be due to a number of things such as refrigerant leaks (my case)...

Excellent suggestions everyone. This is a great community! I just tried combinations of turning off auto hold/reverse braking assist/cross traffic/sensors off/1pd off/ etc. and in my case it didn't help. Truck seems to get confused trying to clear the front wheels over that garage lip when I...

It's frustrating trying to reverse the Lightning into my garage. There's a small rise at the lip of the garage entrance and getting over that is difficult for the front wheels because the truck constantly cuts the power and puts on the brakes because it thinks there are obstacles. The truck...

Interesting. That's 2 data points (including mine) with a bad schrader valve for the Max Tow AC. My dealer had trouble finding the leak initially, before finally locating it at the schrader valve. So for folks with low freon in the Max Tow AC system (which leads to the battery overheating...

Just to clarify - the cooling for Max Tow also uses a separate Air Conditioning compressor that uses refrigerant gas ("freon"), which is not the same as the liquid coolant. In my case, my battery was overheating during charging because the AC compressor wasn't running. The "freon" gas leaked out...

You might be having the same issue I had. The Max Tow cooling system had a freon leak and stopped working. https://www.f150lightningforum.com/forum/threads/psa-fast-charging-derating-significantly-on-hot-days.20209/#post-402220

Good points, just a small correction.... You can buy the Tesla membership one month at a time. You don't have to subscribe for a full year. When I road trip, I'll just buy the $12.99 membership and then cancel the auto-renewal after a few days - it's still valid for the full month. 12.99/10c...

UPDATE: Tried fast charging on a hot day after the dealer fix and it's working normally now! Peaks at 170kW for a few minutes, then holds steady at 133kW then a gradual taper around 70% and then the big taper at 80%. Fans kicked in loudly this time during charging. Car Scanner showed Coolant...

Posting this in case it helps someone else that encounters this issue. TL;DR; Turned out to be a refrigerant leak in the AC system that keeps the battery cool - I have the Max Tow package with the separate cooling system. I don't fast charge often, but recently noticed that in 90F and above...

Poor software programming, plain and simple. And if if was intentional, then that was a really dumb choice. There's no reason the truck should shutoff after unplugging the charge port. The truck shutting off along with the AC shutting off is a frustrating one to keep dealing with when fast...

@Lightning105, I was seeing something similar. Turned out to be a refrigerant leak in the AC system that keeps the battery cool - I have the Max Tow package with the separate cooling system. I don't fast charge often, but recently noticed that in 90F and above weather, when fast charging the...
