You can for standard tires to your wheels.  I’ve fitted all seasons to mine.

so how to charge the "small" battery, I am not getting it, if drive not charge, sit not charge?

It says above.  It needs to be in the ready mode.  I don’t know why you don’t get it?

Frequently have packages, plants, groceries in the front seat.

Anyone have to code to turn the seatbelt buzzer off?

It encourages non use of the belt.  Just click it and load your stuff on the seat.

I decide to register this account to reply to this thread. I believe I know the root cause now.

I have a UX250h 2020 model. The same issue happens to me many times back in 2021 during winter time. I thought it was because I didn't drive it enough. Drove to the dealer performed the check and nothing suspicious. 

This year, couple days ago I experienced the same issue again after wash my car and I probably forgot to lock my car.

This time, I decide to have my car towed to the dealer (I moved to another state), and they were able to find the problem!

Google search L-SB-0036-21 DCM and checkout the pdf on the nhtsa website:

My understanding is that the vehicle was sending the vehicle status to the server and to your lexus app.

This process happens too frequently when vehicle is parked and drained the 12V battery.

 

So you need to bring the car to the dealer and ask them to update the DCM firmware. I haven't got a chance to verify this solves the problem yet but I think it seems to be a reasonable root cause at least.

I hope it works for you but I suspect it won’t.

My first experience today. Called AAA for a Jump that didn't work. Needed to call a tow to Lexus dealership.

Turns out the tow truck driver was more experienced and jumped the battery. He said with the Hybrids you have to have a Charger that is at 100% to work. He tested one he had at 50% and did not work. The one he had at 100% did the trick. The other trick he had was to push down on break and push in the start button and then immediately push down on the gas. Not happy this happened on a car with only 48K Miles but hopefully this info helps someone down the road. I was told to drive for at least a half hour and up hills to recharge the battery fully. Technology continues to make more work!

It’s surprising how much bad information there is on this subject.  In fact, driving for half an hour is unnecessary unless of course you need to go somewhere.   You don’t need to move an inch, just make sure you leave it READY mode for half an hour.   It’s a time function, not a distance function.

I own a 2017 Lexus NX 200T Sport, which comes with a power rear lift gate. Looking to convert the power lift gate to a manual one. Has anyone else done this with a similar vehicle? I'm currently looking for manual lift gate struts that will fit on my vehicle.

I've done this before on a Toyota Highlander XLE, which went great. Now I don't have to worry about the power/automatic system breaking. I know I can do it myself easily once I'm able to find the right parts (manual struts and matching brackets).

Thank you!

What a strange outlook.   Take the engine out and fit pedals while you’re at it.  

It’s a matter of understanding.  
 

The UX doesn’t have an alternator or a starter.  It has two types of battery - a big traction battery that drives the wheels and a small capacity version of the 12V battery on a conventional car.  This small one is the one causing your starting problems.  It’s only job is to power the door locks, heater  and the dashboard so it doesn’t need to be big.  That little battery gets charged by the big battery - think of it like one of those powerbanks you can carry to charge your phone and in just the same way, it needs to be connected to the big battery to work.  It is only connected when the car is in the READY mode.  If you sit in the car waiting or you keep moving it in and out of the garage, you don’t give it time to charge.  If you’re having battery problems you might take it for a drive but the only thing that helps is the time, not the distance.  You can achieve exactly the same by leaving it stood on the drive but it must be in the READY mode i.e. put your foot on the brake and press start.   It may start the engine and it may not - the computer will sort that out but you can reduce the likelihood by switching the heater off.  You can also lock the door with the second key.  If you are not using the car much, half an hour to an hour once a week will stop you having problems as long as you don’t inadvertently discharge the battery by other means.
