Jeep JK ONLY! rack up miles when towing or not?

Hey gang,
Well, I got one that even stumps me here and we've been towing jeeps for over 35 years. A buddy of mine and I were talking the other day and, he has a 2012 Jeep JKR and he stated that, unless he pulls the negative battery cable when he tows, his jeep racks up miles. Well, my answer to him was, if his key is off, then there is no electronic activation of any parts or components so, how could it be racking up mileage?

Linked here is the 2012 Jeep JK owners manual. On page 81, it outlines the procedure for Recreational Vehicle Towing. I won't go in to the details, you can read them for yourself. No mention of leaving the key in any other position, other than OFF. To me, that means no electrical activity so, no registering of mileage when towing.

Now, below is a link to the owners manual for our 2015 JKUR. The outline for prep for towing behind a motor home is almost identical to the 2012 owners manual towing instructions.

Now, I really haven't done an actual check on ours to see if it is, in fact, racking up mileage when we tow it, even though the key is in the motor home. I suspect it's not. Now, just for keeping this thread short and sweet, please do not reply with regards to any other model Jeep, TJ, YJ, CJ etc. Those are not in question here. ONLY the JK model is in question. I should know the answer to this issue since we've been towing for decades but, it's just one of those things that, I've not paid any attention to. Thanks for your participation here.

    One thing to consider is that guy is wrong. He may believe what he said, but that doesn't mean it is actually happening!
  • My 2012 Rubicon doesn't tally towed miles, and I don't leave the key in the ignition. The key in the ACC position and disconnecting the battery was a hold over from when Jeeps had a steering wheel lock. Think they did away with that in late 2010 models. They just didn't bother to update the literature.
  • My 2011 JK doesn't and I thought I'd read on a Jeep forum someplace that this is true for any vehicle with an electronic dash, i.e. one that doesn't have a mechanical speedo.
  • If he's leaving the key in ACC then it is possible. 2012 was about the time FCA fixed the misprint in the OM regarding the need to leave the key in the ACC position when they issued an addendum. They went a few years with incorrect information in the OM's. This has been discussed in several other threads.
