Re: 2013 GC QuadtracII - Recreational Towing

Could you tell if the Jeep computer turned on while towing with the switch off and battery connected? That was an earlier post, I think. I'm having a Roadmaster automatic disconnect installed Friday. It would be great if I didn't have to turn the ignition on, because then I can connect/disconnect the battery from inside the motor home by turning the parking lights off/on. I did tow the Jeep once for 30 miles with the switch off and battery connected, before I read the online manual. Didn't notice any problem, but I guess it's possible the battery would eventually run down. Couldn't we bring 12v from the motor home to keep the Jeep battery charged?

Re: 2013 GC QuadtracII - Recreational Towing

From what I could tell, the entire Jeep was as if I had parked it and walked away. I do not believe the EVIS activated until I opened the door, but honestly I was more interesed in seeing if the mileage logged. Before I went to the time and trouble and expense of installing a battery disconnect I would tow it again and pay special attention to the dash display for the EVIS. We already know the dealer who said the EVIS would log mileage is wrong.
The OM baffles me. Why would they have you leave the key on and disconnect the battery? There is no wheel lock or transmission lock. Given the discrepancy between the OM and the UG, we know someone screwed up. I think it was the Technical Writer for the OM. We'll see...

Re: 2013 GC QuadtracII - Recreational Towing

Well there you have it. For some reason the owners manual must be just flat wrong. Perhaps the dealers that sell these are wrong as well (no perhaps about it). I really do not know why Jeep does not correct this fountain of incorrect knowledge with a technical bulletin or some other form of communication with the owners and prospective owners and for that matter the dealers.

It is ridiculous that a new owner would have to experiment with the new vehicle to find out which manual has the the proper towing procedures. It also helps explain the management mind set that put Jeep is in the bottom two of new rankings in JD Powers rankings for maintenence. If this information had been available and confirmed they would have sold a new Summit to me.

Re: 2013 GC QuadtracII - Recreational Towing

More data: I called Chrysler Customer Assistance again 877-426-5337 and told her of the discussions in this forum. I also told her we had exhausted technical support from dealers and that some of us had cancelled orders for 2013 Jeeps because of this issue.

She made a quick check with her supervisor and told me the battery didn't need to be disconnected. I walked her through the Owners Manual (page 592) and showed her the instructions (steps 12 and 17) to disconnect the battery and told her the User Guide disagreed with that. She said she would escalate this to technical support for resolution and call me back. I'll let you know.

Re: 2013 GC QuadtracII - Recreational Towing

Here's another Jeep GC quirk that may interest some of you: The GC brakelights don't work with the key off. If you need feedback to your coach to show the Toad brake is applied (as in a Brakemaster 9000) This may be a little disconcerting.
However, for some reason the brakelight switch is still hot and active, even though the brakelights aren't. So, you can wire your feed back line to the cold side of the brakelight switch and you don't need to install a relay or a separate switch like Roadmaster says you do. Unless you disconnect the battery and then you're back to square 1.
For my 2013 the correct wire was the white with green trace, second from the front of the switch.

Re: 2013 GC QuadtracII - Recreational Towing

Bingo! I finally got someone (Brenda) at Chrysler Customer Care who checked with their tech support (82K?) and she emailed me this:

Case #: 23129433"This vehicle should not be equipped with a steering wheel lock; therefore, there should be no need to leave the ignition key in the Unlocked Off/ACC position and disconnect the negative battery cable. "

So if you verify that you don't have a steering wheel lock (turn it full right to left with the ignition key OFF), then you can ignore the user manual where it says to disconnect the battery. From the horse's mouth.

Re: 2013 GC QuadtracII - Recreational Towing

End of the saga: I took the 2013 JGC to the local RV repair facility to have the Roadmaster Auto battery Disconnect installed. They do a large number of towbar installations. They told me they had done towbars on several 2013 JGCs, and no one installed a battery disconnect. The guy who installed a Brake Buddy breakaway disconnect on my Jeep said his grandfather had a 2013 JGC Overland like mine that he has towed for a year and never disconnected the battery or put the ignition switch in other than OFF. So I didn't have the auto battery disconnect installed. Consensus is that the 2013 JGC manual is wrong (including my previous post from Chrysler Customer Care).
