Hi all. I have had my 2022 Pacifica PHEV for a couple of months now. I was able to put over 1000 miles on the first tank of gas because the engine kicked in so little during my regular drives. And my commute is so short I could go about 4 days before I would have to plug in with the included L1 charger.

This morning, however, the ICE kicked in almost immediately. I filled the tank a couple of days ago, if that's relevant. Also, it was about 30 degrees F this morning - the first day snow stuck to the ground. The roads were a bit slick; maybe a bit icy.

This is my first PHEV so I'm still learning. Does the ICE kick on when it's cold just because it's cold? I didn't have the heater running. Does it kick on when the stability control detects icy conditions?

I've heard about Fuel and Oil Refresh Mode (FORM) on some PHEVs. I thought I was experiencing this in the past when I was getting close to the bottom of my last tank of gas. But since I just filled up, I didn't figure that's what was going on here.

Has anyone else experienced something similar with a newer Pacifica PHEV?
Thanks!

The same thing happened to me both times it's been driven this week with the temps in the 30s here in Ohio. I don't recall such behavior last winter but maybe I'm simply forgetful.

I am also in Ohio. First meaningful frost of the year this morning and the city didn't salt anything. There were a couple of accidents I know about, but nothing serious. Curious to see how the winter progresses.

So the ICE kicks in depending on the HVAC temp that you're requesting, I can kick on ICE on demand if its below 40 degrees and you switch fan to high, just rotate the dial all the way to the right. But also if you're on Auto at 75 degrees for example and its cold outside then it will also kick in ICE to help heat up the coolant.

My wife drives ours so I can't say whether the ICE has kicked in earlier/continually, but she did comment about how the expected electric miles dropped from the usual high 30s to high 20s and we were figuring it had something to do with the temperature drop.

A range reduction of one-third or more in cold weather has been the norm reported and my experience last winter.

Okay, thank you. That lines up with my experience today. I wish there was a better explanation for why stuff was happening in the van's user interface.

No heat no ac the engine doesn't kick in I live in Florida so the AC is on almost constantly . We had a cool day not long ago and I didn't turn anything on and was surprised at the sudden electric only quiet

My experience is that the ICE will turn on below ~30F even if the HVAC is off and the cabin has been pre-heated on L2 electric. (That is - the car thinks it's below ~30F - parking in a warmer garage will of course, prevent this).

This is not true in my 2022 - with cabin conditioning and no climate I have driven the van in weather well below 30°F without the ice coming on even when temps were at 0°. It is certainly more likely to engage ice however with any additional needs like climate controls or acceleration etc.

Yeah, we are only just getting to regular temps below 30F so I haven't had a lot of opportunities to see its behavior. I recall that last year I was able to keep the ICE off even below 30, but so far the few times I've tried this year - cabin fully conditioned on L2, HVAC off before starting, the ICE fired right up every time.

Same experience here on a 17.
