This is a new Rubicon only 10 miles on the unit. When I select 4x4 mode, it will engage and run fine, but if i excede 10 mph the green 4x4 light start to flash. The only way to get it back into 4x4 is to shut the key off then back on . Anyone know whats going on here ? is it normal for the 4x4 to dissengage if im running faster than 10 mph ?

Thanks

 

I have never heard of that ever happening. I run mine through mud faster that that and have know problem. might want to get that looked at.
