Does mileage add while towing.
 
I just bought a 2013 Ford C Max and plan to tow it about 7000 miles this year. Will those miles add to my odometer, thereby reducing my warrantee? The dealership said they aren't sure, not reassuring.

Nope. I think all modern age cars have electronic odometers which don't register miles while towing.

I can't answer your question, but have often wondered about those miles. You are certainly putting miles on your tires and maybe parts of the drivetrain, but the engine is not running. I'm guessing/betting that those towed miles do not show up on the odometer. Someone smarter than I am will give us both an answer soon.

Oops, RickO beat my poet.

The wife has a 2010 car that we've towed for years on a tow dolly. We always joke that it's got about 30,000 miles on the front wheels and about 45,000 miles on the back!

Our Jeep does not accumulate miles while being towed 4-down..

Of course, time spent RVing doesn't count against ones' lifetime allotment of time on this planet either, so I guess it's all good! :thumb:

No accumulation on our 2010 GMC Acadia...at least on the odometer. :cool:

My 2007 H3 Hummer has been a great tow. Not only does mileage not accrue on the odometer, it requires no fuses pulled, key does not stay in the ignition while towing and the doors need to be locked; so you keep the keys. The transfer case is put in neutral and the tranny is put in Park! The front wheels turn freely in this configuration, and she tracks well and brakes great with the Air Force One system which I installed after trying several other systems. But again, mileage does not register and most all vehicles are set up to not accrue, I believe.
Good luck to you.

I have a C Max, and have towed it over 6,000 miles. Mileage does not accumulate on the odometer unless you leave it in the "Run" position.

One caution, however, you MUST use a charge line. With key or button in the accessory position there is just too much drain on the battery and it will run down in 2-3 hours. Eventually it will trash the battery.

The C Max is worse about this than other cars because the 12 V battery is very small and runs down quickly when towing. It doesn't start the engine so doesn't really have much to do so doesn't have to be large. Problem is, it dies, car won't start because it needs the 12v batter to run the system and tell the High Voltage battery to start the engine.

In your case I'll join the NO chorus.

For others who have this same question......

IN days of old when folks were bold and 10 MPG was considered Great economy (Remember those days) Odometers were driven mechanically off a gear on the transmission output shaft or, in a very few cases, by a front wheel hub (I seriously doubt you will ever see a car like that) and yes, Millage rolled up with every turn of the wheels.

Unless...

1: You installed a disconenct
2: A drive shaft disconnect (Remco) needed on some RWD automatics
3: An Axel Lock (Remco) needed on some FWD automatics.

Not sure about 4wd.s If it's the transmission output shaft then they would not rack up proper millage with transfer case in LOW,

Today, however, Most are operated electronically and unless the ignition is ON, they do not operate at all.

Oh, an open door or key in lock may turn the display on, but the sensors are dead till you crank that sucker up.

So nothing adds.

our Escape doesn't register any miles.

I'm not understanding what you mean about a "charge line." Is this in the owners manual or something you learned by experience.

good good note to keep in mind when using a transfre case in neutral

some car/trucks have a safety fetcher that if power is lost but comes back latter the transfre case well reset back in to gear to where the car would be in park

it is rear to have it happen but you see this more way way upstate where its cold and have a soon to be bad battery cold brings the volts down and pop when it comes back up

this is more for any one running a bypass for lighting on towed

just some thing for every one to keep in mind

You have to run a 12 volt line from your motorhome to your toad to keep the toad's battery charged. Not uncommon in newer cars to need this. Blue Ox and others make wiring kits for this function.

John, You can tow the Ford Hybrid with all 4 on the ground? I was under the impression that this was a no-no.

I'm assuming it's a FWD automatic (don't know anything about this specific model). Can you provide any details?
