Re: Driveway-rated ?

My vote is for a frozen ABS sensor. With our cars, brakes are applied intermittently to keep the wheels spinning at the same rate. So heat from the brakes melted the snow around the sensors and after you stopped, you stopped in snow, continued to be a wet environment and eventually it froze.

You got the error AFTER the car had been stopped for a while, not while you were off-roading in the driveway.

Your car would have been fine if the sensors defrosted.

Make sure the dealer doesn't try and screw with you.

Re: Driveway-rated ?

I blame tires as the reason for getting stuck

Re: Driveway-rated ?

Add to that the elimination of a front LSD that QDII used to have.

Definitely not the tires !

So..guess what. After the car gets towed and dropped at the dealership and spends the night there, it started working as nothing happened. Dealer said they found tons of codes but everything was just stored ( logged) and nothing active.
So as somebody was saying could have been a frozen sensor or brakes froze? cos yeah everything happened after I stopped the car and shoveled for couple hours ...but really?! It was not even below 0 F Should I expect this to happen again? Lol
Dealer couldn't give an answer ... Just told me to let them know if it happens again lol
At least I got a frigging crysler 200 for one day )
They drive the car around tested and nothing. Took her home on a 30 mile road ..all good.
Shes out in cold now. She wont see the inside of my garage yet !!
I love her but she can be such a bitch sometimes.

Well I said that about your frozen ABS sensors.
I am the voice of universal truths , a statement backed entirely by the undeniable fact that water freezes at 32 deg. Fahrenheit = 0 deg. Celsius. So there's a considerable range of temperatures there between 0 F and 32 F for water to freeze on your ABS sensors...

Re: Driveway-rated ?

Although I'm european and recently moved to US I'm aware that 0F is below freezing point :P
But i dont consider 0F smth extreme. How about -10 -20 ?
I know i have an engine heater that's gonna come in handy at -10 -20 but how about the ABS sensor? Lol

So, you've got a nice American model, but she's frigid. At least she's back to performing well.

We're not going to discuss here which one of us is more European. But I have probably been in US longer than you. While - 10 deg F is plenty cold (and not a temperature I grew up with) but I don't think it makes a realistic difference on how fast moisture on a 1-2 cm square metal part would freeze, whether at 0 F or -10 F. It will make a difference if we're trying to freeze a lake but not that tiny piece.

Here's an ASHRAE calculation, though not directly applicable to the situation at hand, it offers an insight that after a certain temperature difference, the effect is not as much. The shape of the curve is logarithmic.
Mechanical Insulation Design Guide - Estimate Time to Freezing for Water in an Insulated Pipe | Whole Building Design Guide

Initial Water Temp in pipes = 35 deg F
Ambient Temp = 0 deg F
Freezing time = 3.2 hrs
Ambient Temp = -10 deg F
Freezing time = 2.5 hrs
Ambient Temp = -20 deg F
Freezing time = 2 hrs

----
The ABS sensor - well not much you can do aside from melting the ice.

Re: Driveway-rated ?

My point was that I don't think it's normal for a car to behave like that when left out at 0F or -10F or -20F
Seems like a design flaw. Usually your battery gets drained or the engine doesn't start if it's way cold... now we have to worry about abs sensors ?
I guess I'll pack a hair blower in my trunk and use it on the wheels when it's getting chilly outside

It's normal. Happens more than you would think. Had it happen on my Subaru up in VT. Luckily I remembered to pack a spray bottle of alcohol. Couple squirts on the sensors in the rear got it cleaned up.Now, under clear weather it won't be a problem. Only when it is wet or snowy and water forms ice over the sensors. It happens at 30*f and it happens at -30*f. More likely to happen at temperatures below the working point of the chemical melting agents. No flaw in design, just physics. Snow, ice, mud or even leaves can and do get slung up and isolate the sensors.
I'm actually surprised, since you live in the NE that you nor any one else tried a heat gun on the wheels. A lot of tow trucks carry them for that reason. Also stuck E brakes. I see it all the time at ski resorts.
Another option is that the GC was turned off too quickly after you had the wheels spinning. A quick disconnect of the battery would have solved that.

Re: Driveway-rated ?

I had that happen on the Subaru as well. I have a Legacy GT and a Forester - the Legacy is the mechanical, analog monster but the Forester has modern day electronics. But, as I professed in another thread, for winter driving I prefer the electronics of the Jeep over the mechanical Limited Slip Differentials on the Subaru Legacy GT.
