Was ICE cold weather start formula reprogrammed?

Thu Nov 25, 2021 6:00 am

I apologize for bringing this topic up again. I have tried searching the previous threads for an exact answer to some of my questions but can't seem to quite get them.

Here is my situation:

2018 model purchased and driven in upstate NY. Basically, one of the big reasons I purchased the Outlander was the EV button. I knew that PHEVs love to turn on the ice in cold weather. From reading the EV button description, it seemed logical that if I did not use cabin heat and did not mash the accelerator, I could drive the Outlander in my weather without the ICE.

It seemed as though this was true when I first got it. If I preheated the car and held down EV and put it in ECO and didn't use the cabin heater, I could go without ICE even in freezing temperatures. Then something changed. Now, if it is anywhere near 40 degrees F, the ICE can not wait to fire up. If I preheat the car for 20 minutes, I can get it to not start the ICE at start up or when I back out of the driveway. However, as soon as I get up to about 10 mph, ICE kicks on. I am as gentle as is humanly possible with the gas pedal.

What changed? Was something reprogrammed or does some switch start to wear and make it more likely to switch on the ICE?

I can see no sense in starting the ICE when I am driving at 30 mph and it is clearly not doing it to heat the car (if it did that, it would just start immediately and, again, I'm not trying to heat the car). At 30 mph, I would not want the ICE to help with acceleration anyway to avoid an accident so I wouldn't be asking for it to fire up without warming up. If Mitsu is trying to save the ICE, what would do more damage? 100 unneeded startups during the winter or one highly unlikely demand of the ICE to accelerate quickly?

I see there is a highly technical and invasive fix being worked on in another thread. I don't want to get into something like that that will void my warranty. However, if Mitsu could reprogram my car or replace a bad part so that I can reasonably drive this thing in EV in cold weather, that would be great.

Right now, on most of my trips, I drive for two miles with the ICE running the whole time doing absolutely nothing of benefit, park, return to a cold ICE which starts up again for the two mile return trip serving no purpose. I now basically has a gas car for four months a year!

Given the litigious nature of the US, Mitsu have to design for a worse case scenario (as Nissan found out to their cost), so they have to take into account the weather extremes of the north American market and wide differences in customer usage - including people who might damage the car by being stupid. After all you have warnings on takeaway coffee!

If you are doing so many short trips then perhaps you should have bought a BEV? Oh, and yes there does seem to be evidence that Mitsu tweaked the software to increase the incidence of ICE start-ups - probably upgraded when serviced. .

We have the UK 2020 model, over the last few days overnight we have experienced -1 c, if I leave the heater in the on position set at 22 c the ICE unit has started to fire up first thing in the morning, however if I leave the heater set at 18 c it has not fire up the ICE unit yet.

In the winter I normally leave the heater in the off position but set at 18 c, when I start the car I press the EV mode, press ECO then switch the heater on, however as far as I can remember when we are down to -4c the ICE will fire up.

40 Fahrenheit is approximately 4.44 Celsius, definitely a different program.

A lot of folks have a suspicion that the car was reprogrammed, but it is not clear or proven.
I myself bought the vehicle (used) last summer and when the cold weather came 5deg Celsius was the critical point for me. On every short trip the ICE was coming on after a minute of driving only to be shut down by parking the vehicle without even fully warmed up.
So i had to do the invasive fix you talk about.
Some owners were pissed of and complaining a lot to their dealerships so the head office suggested battery service to be performed an... miracle, their engines went back to be quite again. I did it as well. BMU double reset followed by DBCAM procedure fixed the issue. Now in cold weather the ICE is coming to live only when my state of charge is under thirty-ish percent. The really cold weather didn't start yet but sure the procedure works and the culprit is the BMU.

So, you (well, some of you) are buying a $50K (Canadian) car and driving around in the cold with heavy boots, pants and coats on? Reminds me of my first car, a '59 VW with no heat. Used to have a scraper in one hand to keep a little patch of the windshield cleared off. An electric bike would be cheaper for you ... and have the bonus of not having a windshield to scrape.

Sorry ... but this thread just keeps coming around time and time again and I just don't get it.

This does seem to be a particular problem in North America only.

The temperature is down to zero here, and I found that activating both the EV and ECO buttons will kill the ICE instantly.

Well smarty some of us have built a perfect daily commute. 3 km. from home to wife's work and another 3km. to my work.
The vehicle is perfectly fine and cozy when preheated. Windshield perfectly clear without any scraping. We have an electric heater you know.

Opposite to your suggestion we should be wearing heavy boots and coats if I count on ICE to warm up the vehicle in that distance.

Update for the interested party... Last winter ICE kicking in constantly under 5deg Celsius. After an DBCAM procedure this winter -5deg Celsius and no ICE coming to life without a reason.
