Does the owners manual address this---I thought Cherokees were towable 4 down but perhaps 2 wheel drive is the difference. Some vehicles suggest a fuse to be removed---at least one person has said to me it was for the odometer. True/false????
Mine does not accumulate but I do keep a log of miles towed as a hedge just in case I had to make a warranty claim. If your friend had such a log in the future he could substantiate towed vs driven miles----not comforting but a thought.
There is the old remove the drive shaft gambit.
