Info if you are at -17 and have the block heater plugged in
 
Been a long time lurker here, traded in our 2013 Jeep Grand Cherokee limited for a 2014 Summit with the Diesel. We had it for a week and it was 19 below last night so I had the block heater going.

Went out this morning at 6am to start it up and she threw codes right away, I eased her out of the garage and up to the house to let her warm up, gave her 30 min and went back out and no headlights, if I flashed them with the turn signal handle the lighting went dim.

Restarted her a few times and got headlights but then she was only giving me 3rd grear so I knew we were in limp mode.

Called the shop and they got a wrecker out here to take her in. When we got there I started it up and it gave me normal transmission gear of 1st when I put her in gear.

They called Chrysler and they said the problem is a known one of being that cold with a block heater, they are working on a update.

The codes we got were P24c2-00 and P2E0c-00. Got my auto start installed and our hitch and they cleared up the codes, so far so good coming home.

Hope this helps anyone else in the cold areas. We had not planned on trading in, in fact I had purchased the lifetime warranty in October on ours, the GM at our dealer had came out and just said they sold his jeep and he wanted ours that was a Winter Chill color. He gave us a heck of a deal to trade it in, we are enjoying the Summit a lot more than I thought I would.

Thanks for sharing this, please keep us updated! I would hope it would ultimately start in -19 F even without block heater.

I really hope they didn't charge you to "install a hitch" on a Summit - all the Summits have them from the factory, just pull the center section of the rear fascia to get to it.

racer-xerols On the hitch, ours did not have one, we got on the floor and looked the wiring was there but no hitch, we had made it part of the deal.

stratoblaster, up here in the Dakota's if it's below 0 I plug in any Diesels that I plan to start to help them out starting. If we are running around late going to a casino or something I don't worry about it the Jeep has been good down to -20 and sitting for a couple hours it had no problems starting.

We are pretty happy with it, by what I understand that the block heater being plugged in the computer looks at the coolant temp, oil temp, air temp to do the start-up, it sees the odd coolant temp and it threw the code.

Similar story - -17 outside but I didn't have the block heater on. Got in and it wouldn't start. Plugged in the block heater and waited 2 hours and went back out to crank her up. She started but threw a bunch of codes and ran extremely rough. My oil temp was at 4F and my trans temp was at 2F. Waited about 10 minutes and then took it for a highway drive for about 20 minutes. After that, no problems.

I still have the check engine light on and Dash is showing a couple of unknown codes. Somebody on the forum said to wait about 60-70 miles to see if the light goes off. If it doesn't in the next 30-40 miles I'm taking it in.

Lesson learned - keep the engine block heater on.

That was going to be my question. What happens if I go up to the mountains for a weekend and the car sits for a day or two at -10 and no way to hook up the block heater? What do people do?

We've been driving diesels for over 30 years up here, right now everything in my shop is a diesel, if it's below 0 even with glow plugs if they have been sitting they will need some help getting started.

On my tractors I can cheat and hit the switch and wait until the glow plugs go out and turn it off and back on for a second hit, I do that when it's like 10 above and it helps them but they don't always start right off in them temps.

If you have a cabin in the woods that you own or like to go to I would look into a small generator to carry along so you can run it for a couple hours to help it out. At -10 I've had diesels not start, even with good winter fuel and a battery boost it's just too cold for them to hit without a little help.

Our first diesel was a 84 Chev Blazer with the 6.2, then got a 94 Suburban with the 6.5 turbo, then we went to the 2006 Silverado with the LBZ Duramax (still have that one) and right now we have a 2007 T2220 New Holland Tractor and a Case IH Farmall DX60 Tractor. All are diesels.

The only thing gas in our shop is my Harley, two ATV's and a ATV mower and our farm generator is gas.

ThumperButtercup - Thanks, I'm buying a 100ft extension cord to bring with me in case I need to plug-in somewhere. Any recommendations on a small portable generator I could take with on a road trip?

I never carry over 25' of extension cord, also figure a way to secure it like dropping it down the engine area and tying it to something so it cannot be stolen so easy. Get a good 12 gauge wire cord also, I've gotten away with 14 gauge but I like the heaver cords for the block heaters.

I've been known to carry a spare cord in-case someone has cut one to steal what they can. The motels up here all have plug-in's in the parking lots if you need them in the winter.

As for the generator if I was just going to use it for the jeep you could get something small like this.
