Yeah it was the first I had heard about it until it happened to me, even the dealership couldn't troubleshoot it properly I has to rip out my FSM and do some troubleshooting myself after they told me "4x4 working fine" even though I told the service adviser to put in "Front Axle lock light flashing, locker engaging, pump working, suspect sensor in diff"
its not common for the sensors to fail, unless someone over tightens the fill plug, which wasn't the case cause it was working fine while 4x4ing then just started flashing instead instead of showing locked.
The dealership even told me before opening the diff that it would only be a hour of work, even though the FSM said they had to pull the diff apart and I read online it could be closer to a couple hours, sure enough when I picked it up latter that day it was 7 hours of labour...
