I could live with that except that without an Embedded Battery Heater in the Battery Pack, when not charging by Charge Port Cable the Battery Temperature drops down to and stays at the outside Ambient Temperature since the HVAC does not warm up the Battery when it is on.

Driving my 2024 in the city and Highway last Friday when Temperatures were -16'C with the ICE running 100% of the time, driving the car on ICe did not increase the Main Battery Temperature at all.

My biggest complaint is that the 2023 to 2025 PHEVs no longer has an embedded Battery Heater inside the Battery Pack

Looks like Mitsubishi Engineers worry more about the ICE than they do about the Main Drive Battery since they programed the car to demand that we add at least 20 L of fuel every 3 months but decided not to include an embedded Resistive Battery within the Battery Pack.

I can now confirm that plugging in the car does heat up the Battery as my Temperature gauge increased from being on the left vertical bar (1/5th way of horizontal bar outside temp was -12'C) and increased to 1/4 of the gauge, after charging.

This heating however was produced by charging the cells at 3.7kW. This heating is not done by any Heater as there no longer one in the Battery Pack.


It is important to add that at -12'C, when the Battery Level was at 5 kms left in range the car did go into EV Mode but was in Limp Mode because pushing the pedal to floor did not power the wheels past 30 kph.

Sorry, wrong Photo. The one I took at midnight did not save.
This is similar to my experience (except for any warming effect when plugged in). The point to remember is that when the temperature drops sufficiently, the battery is locked out and will not charge. The same is true once the battery is fully charged.

The absence of a battery heater, as you say, is the root of the problem - the same battery heater that was advertised as standard equipment in the '23 model but was not included.

The issue of cold start operation specifically aside, the way it has mistreated (and lied to) its customers should serve as a loud warning to anyone thinking about even buying a lug nut from Mitsubishi.

This picture is from this past Saturday the car starter and drove without issues after it spent 5 ~6 hours parked outside not plugged in.

My wife got her Outlander 1st half of November and drove to work every day since. The car spends the nights in an attached but not heated garage and outside all day (9 hours) at work but plugged in to 120V. No issues and we had a few days (felt like weeks) around negative 16 Celsius. But we are experiencing and rise in temperatures for the upcoming days (common occurrence around Calgary area). She is loving the vehicle and reported no issues and good behaviour driving on Snow (we had some around here).

Will keep you posted but generally February is coldest winter month.

Glad to read that she is enjoying the car and has had no starting problems .... yet. I hope she never does.

SInce the Battery range on your photo is displaying (42kms) the Battery Temperature must be to the right of the left white line.

Can you post a photo of the Battery Temperature, please? My 2024 shows - - - when my Battery Temperature is on the white line or to the left of the line.
 
Well i was just about to post about this, its -8 celsius and my car is dead. wont even charge. This could have been a life or death situation out where i live.
 
As far as I am aware a block heater or engine heater, or even oil pan heater will not help if your car is too cold to start. It's not the engine, it's the battery that is too cold. The main battery (not 12V) is used to start the engine. So if your car is too cold to start and you are in that situation there is really nothing you can do until the temperature (and thus battery) warms up enough. My question is, if it's super cold out and you have your car plugged in, is that enough to keep it "alive" even in the cold? I am not 100% certain of the answer. The engineer from Mitsu some people have mentioned (His name is Honda) said to leave it plugged in. I only own a 2018 so my car has the dedicated battery heater. Would be nice to know from the 2023+ owners if you have your car plugged in in sub -30 temps does it still start vs. leaving it unplugged.
I have a 2018 also. My 12 V battery is dead. This was the first winter that I parked outside (not expecting a problem). The temperatures the day it went weak (warning signals flashing all over the dash) and finally died were only about 20-25 F (-6or -7C). What is the battery heater that you mention... and that other people have commented on?
Also could not get enough of a charge from a jump to keep it running when cables were removed. I need a new battery but cannot find any of the replacements mentioned in the forum. They are all either out or do not ship to the US. I called 2 dealer part depts and they did not return my call! Any advice would be appreciated.
For North America the 2018 to 2022 PHEVs did have a Resistive Cab Heater that worked till the Temperature dropped below -10'C and we wore winter wear. If we wanted to stay warm and increase the request for heat the ICE would start up but then, selecting temp of 18 or 19'C the EV Mode would turn back on again and kept the Cab Luke warm.

The other big difference for the 2018 to 2022 is that these years had a Resistive Heater inbended in the Drive Battery Box. The 2023 to 2025 do not, and only use a Heat Pump, which does not warm the Battery at all, so there is no way to keep the Battery warm nor from freezing up.

Worst part with these post 2022 PHEV is that once the Battery Temperature reaches -25'C not only may the Car not be started to Ready but the ICE may not even start at all until the Battery Temperature warms up.

I have even read reports that once the Battery gets that cold, since the Computef liberally turns off the operation, charging the Battery may not be possible.

Had I know all this before I would have stayed with my 2022.

For Temperatures above 0'C I can attest that these post 2023 PHEVs are great cars but not at all for Temperatures below -10'C

The Battery Heater we are referring is for the Drive Battery Battery Pack (under the floor of the Car.

As far as your 12V Battery goes, there is a thread on a replacement Battery I will link tge post when I find it.
