Please Respond @jeepcares - Major Issue w/ 4xE Brand New

[Chris262]

I personally wouldn't call 20-35 degrees farenheit 'mild'. 32 is freezing, and 20 degrees is pretty damn cold. I read the other thread and it amazes me that people are buying into this technology in cold weather states. Even in milder states, it still gets cold from time to time and personally I wouldn't want a vehicle that is going to freeze up on me during a cold stretch. That's just me.

Chrysler in general is way behind on anything hybrid, EV related. I work at Kia and the first generation of an electric Soul was not allowed to be sold anywhere but warm climate states. 7 years later and we have multiple plug in hybrids and full electric vehicles that work in any climate. But from what I read on the Wrangler forum all of these "issues" are normal. It sucks but it is what it is... Another reason why I stay away from first generation technology of anything to be honest.

When I lived in MN for 10 years, we always felt like there were levels. 11-32 felt pretty similar, single digits started getting cold, below 0 to -10 was frikking cold, and under -10 was just painful. My second to last year there the entire month of January never got above -5 and it was just absolutely miserable.

This seems insane. For any type of EV to catch on it needs to be easy and usable. The buyer should not have to get a degree to drive the vehicle.

Thank the EPA.
Hold onto your shorts - They just released new rules and you are going to be seeing more and more of this and worse. The EPA is even exceeding what the president suggested.

The new target raises the fleet average fuel economy requirement by 25% from 32 mpg to 40 mpg. President Biden had previously proposed a 38 mpg requirement in August and has encouraged automakers to transition their lineups to 50% electric vehicles by 2030.

The Alliance for Automotive Innovation, which represents most consumer automakers, called the plan "aggressive" and said meeting the standards "will undoubtedly require enactment of supportive governmental policies – including consumer incentives, substantial infrastructure growth, fleet requirements, and support for U.S. manufacturing and supply chain development."
In other words, to make it, it will mean consumer incentives, tax breaks and money to be poured in.
We don't have the capacity to build batteries that fast, the environmental impact will be substantial and technology will be pushed out before it's ready - like is already happening.
No way such vehicles would work for us here in Iowa when we can have a month of temps below 30 degrees. We don't have a heated garage (like the OP obviously has) so our vehicle would be COLD - the ICE would be required to warm the interior and the batteries. We'd get to our destination before the oil was warm.

Man some crazy stuff here. I live in central IL, my wife has the 4xe and we love it! Temps do get very low here and have while we owned the 4xe. When we first got, the vehicle we had a similar problem of the full electric not coming on and not working much in 4xe mode. I hooked up HP tuners and realized the Battery management system was not meeting the qualifying heating and cooling temps to trigger electric operating mode. I found the coolant pump for the battery right behind the the drivers side front wheel. The connector is pretty much exposed to that wheel and ours was in ruff shape. I got it connected to the pump and it started working better for EV bit was still having issues. When I took it to the dealer I walked through everything with them. They ordered a new pump and had to purge the coolant system. He also told me there where 42 software updates for it. This was in the spring of this year. We have not had any issues since. It has been below freezing a number of days recently, and we have had no issues. With that said , full transparency, it sits in a heated garage overnight.

So this whole warming the internal combustion engine thing, does not make since to me, and wveryone talking about heating and cooling needing the ice are just incorrect. One of the big technology pieces of the 4xe is the electric heating and cooling module under the passenger side floorboard, which has and engine oil coolant circuit as well as one for the cabin. It warms the jeep faster than the ICE can. Neat little unit.

42 software updates for it.

omg....

Glad yours is working for you - but that sounds like something NOT ready for release. Vehicles need to work in remote areas and not be expected to only operate where a dealer is in range.

Owners shouldn't be beta testing cars. Software is pure cancer.

One month under 30? You’re out of your depth. We have winter from October until May. Again, this is our 4th plug-in, something you clearly know nothing about. The first three worked perfectly year round. Also, before you make assumptions as if they were fact, maybe you should ask. Our cars are in the driveway. And our plugins are plugged into 240v outside.

Just to be clear the car still runs, it just runs in pure ICE with out using the battery/electric drivetrain.

How do they account for the engine never warming up and being like any engine that's only ever started and run for short periods of time but never warmed enough to heat the oil and remove contamination? Engines that never reach operating temperatures for 15-20 minutes die early deaths. I've proof in my garage and have seen instances of vehicles driven for only 15 minutes and then shut down, week after week.

Your proof is AMC oil pans from the 70’s and 80’s. Things have changed a bit. I too had a CJ7 with an original AMC 304. I’d never expect it to do what modern engines can. Sounded amazing though.

That was quite a few for one update, but that is not out of the ordinary since about 2018. Software updates have been running rampant and many dealerships and brands that are not tech savy to it really struggle. The diesel's heavy and light duty, have huge updates on a regular basis. Some good some bad, but they all are usually skirting around performance and emissions. When VW got in trouble, it was sad and comical how many updates came out.

You do realize that can and often does mean WAY under 30 where we may have a day that hits 30.
We've had weeks of highs that rose up to -20. We had one year where a pile of dirt that was dug the December before for a new well didn't thaw until May.
It's not Alaska by any means - but there are times when the ice forms we don't lose it for months.

You did mention your Jeep was 70 degrees inside at one point - sounded like the thing was nice and cozy when ya got into it.

That's going to be another issue with plug-in cars and trucks....... there's a whole lot of the population that has no attached garage and almost as many that won't have the capability to charge them without special wiring being run. I'd have to run a circuit in our garage to handle plugging one in.

It monitors fuel and oil, and has a runtime routine to ensure both are circulated a minimum amount of time per runtime. It will indicate on the dash while in this mode. Forget what it says exactly as I don't see it much cause I like the power from using the full drive system. ICE and electric together. Here is a picture of the heating cooling unit I was talking about. They have thought about the cold oil start and have addressed it .

That hasn't changed. You don't warm the oil to boil out the contamination, you ruin parts. There's pictures out there on the web of etched bearings from the acids that form. That hasn't changed much over the years.
Oil is better, filters are better, but contamination and moisture are still a problem.
That hasn't changed.
I still rebuild and restore cars and rebuild engines and see what happens.

This should never happen->
