Hi well just couple days ago drive to mountains it was 5 f and in the morning was everything grate but after driving 20 minutes windows start rolling down it's self ...so me and my wife keep finger's at the bottom up wast fun at all ...but range yes was not to bad ...
I've never seen, or heard, of anything like that. Did you try a soft reset (press down on both scroll buttons in the steering wheel until the screen resets)? Did the problem recur after you shut down, locked, and returned to the truck?

Drove over to Mom's place last night to watch OSU vs ND. Its about 16 miles to get there. I preconditioned without being plugged in as my wife's MY was on the cord. Drove over and let Big Red sit from 5:30 until end of the game. I preheated again without being plugged in and the I sat down in the seat I saw that from the initial 240 miles the range was down to 150 or so. By the time we got home it was down to 110. I left Big Red outside as I am working at home today but I was astounded how much loss there was on this short trip. But the temperatures were quite cold. When we left at 5:00 it was 12 degrees and at the end of the game we were all worked up from the excitement and it was a shocking 3 degrees outside. But the cabin was toasty! I do like my truck but the power use was tough to take. For our trip to Cincinnati this weekend I will have to opt for the MY instead of Big Red. Especially since I don't have free supercharging like these "Johnny come lately" guys are getting with a new FS purchase. I am still sore about that. Come on

Yes I did that first thing but it's help at all ...but after hour drive to home temperature was warmer a little bit then it's stop doing that ...but not completely waiting my service appointment wich take to wait couple months...I did call t4ska about that ..they told me to call for service and I have 28000 miles on my truck

I noticed the LFP batteries are not as good as our 22 model Y battery in cold weather.

I drove from Edmonton to Edson, Alberta yesterday in about -19C, having set off preconditioned from a warm garage with 510km range at 100% charge. Edson is about 210km from my house, so that's 42% of 510km. I arrived with 22% charge left, driving almost entirely on FSD, meaning I actually consumed 78% instead of 42%.

I'm in Jasper now and it sat overnight outside in about -15C; it lost 5% points of charge in 8 hours.

I wouldn't want to leave it unplugged at the airport in these parts for more than a couple of days.

In the app under schedule.
yes, but there should be a pre-condition option under the climate control section on the app. I never leave the house at the same time everday, so the schedule option doesn't work for me.

I turn the truck on defrost and then send the nearest super charger to the navigation screen. Only way I can figure out get the battery to condition and heat up ahead of time.

Once I'm ready to leave, I cancel the SC visit and go to intended destination

Hmmm, Yesterday I left Home -1°F after 80% charge. The CT (AWD core wheels Low height) was in the garage and interior cabin temp was 11°F. I drive 16 miles to work 1/2 country road and 1/2 highway. 16 Miles Home same route. That used 25% Battery when I parked backed in the Garage. I lose about 7% overnight in the cold even thought its in the garage. I will expect to lose about the same today maybe worse. I will be close to 20% when I get home est. So in two days Driving I will have to charge again tonight. and hope temps go up enough to get to work the next 3 days or I will be charging again on Thursday.
Yes I try to use the cruise almost everywhere, but I have seen power use between 1.6 to 2.8 Kw per mi before I get 500ft from the house. I would love to get 2.8 mi/Kw but it is not happening. This is obviously my first winter with a electric vehicle, so I have no ideal what to expect, my neighbor has a Tesla 3 for over 4 years and he tells me in the winter they charge it every night....not much help there. I really don't get this preconditioning bit here? If this was so important why do we not have a button on the app to "Do it Now'. Why is it a schedule task, and how much loss do you incur doing that before you drive verses just driving? Better worst? Any Studies here? And honestly what is the difference between Preconditioning and turning on the cabin heat?
I am still learning guys so please don't shoot the curious person here :)

Here are a few tips that will aid your real-world range:

- When it's super cold, or super hot, keep the vehicle plugged in at least overnight if at all possible.
- Preconditioning matters a lot in the above conditions, using wall power to heat the battery pack and vehicle means that when you depart the power in your battery can primarily be used for moving the vehicle/driving = longer range; maintaining cabin temps (if pre-heated/cooled) takes a lot less energy than first attaining those temps as a steady-state
- if you can garage when it's super-cold, even if the garage is unheated, do try to squeeze into the garage. Bonus points if you're garaged and connected to power.

In ambient conditions of 50-85 degrees Farenheit, it doesn't matter so much if you plug in once or twice a week and never precondition since the battery is already in an operable temperature range and it won't take much power to heat/cool the cabin to a comfortable level. But if you need to add 70 degrees to the cabin temp AND heat the battery pack by 70 degrees it's going to consume a lot of juice - ideally that juice is coming from the wall.

In normal conditions, my truck is parked outside year-round in NJ but when it gets below freezing you can bet I'm garaging it overnight and connected to power. If it's sub-15 degrees, as it is today, it's garaged all day between trips. Meanwhile, the Model Y is sitting outside (sorry buddy) but Cybertruck takes the garage.

Did you have a lot of snow tracked into the vehicle? Condensation or moisture into the door switch bank could do that.

Preconditioning is primarily for the battery, not for the cabin. Yes, you get the benefit of the cabin being raised to your desired temp, but the primary reason is normally to get the battery sufficiently warmed up to get better w/mile and/or for fast(er) charging.

Was the 7% loss real, or 7% blue bars due to the cold?
If you defrost the truck (or activate climate in general) from the app it will also warm the pack.
To really heat it up requires unplugging, sitting in the truck, and setting destination to a Supercharger (no need to drive). This is only worthwhile if starting a long trip and you have time to top off the charge afterwards. It pulls around 16kW in this mode, so 10 minutes with Supercharger preheating is around 3% soc and takes 20-30 minutes to replace.

Unfortunately, Tesla uses the term "preconditioning" to refer both to climate controls and to battery temperature management.

The option in the app is for cabin climate. The battery preconditioning is not a user-selectable option, but rather is automatic when a Supercharger is the selected destination.

The advantage of activating climate before departure is that it uses shore power.
