Differential Unit problems of the 2021 Jeep Wrangler

Dash warning “service axle locker system” . I have never used my axle lockers once, nor been off road with my Jeep & the differential tried to lock itself. This is dangerous. If differential locks could cause fatalities. Yes, have taken my Jeep to the dealership 3 times, it is currently under investigation, have had the rear diff replaced once, the reason: diff oil slowly works its way inside the sensor over time and since diff oil has metallic flakes in it from the bearings/gears it will cause the circuit board in the locker sensor to short out. Once that happens the only fix is a new axle. You cannot buy the sensor separately. Not isolated situation. Many Wrangler owners from 2018 to 2021 posting this up.

2021 rubicon 88 days old 2097 miles. 3/27/2021. Purchased 1/3/2021. Dash warning intermittent service axle locker system. I have never used my axle lockers once. Came on after riding up a very short dirt hill in 4l after shifting back to 4h then my dash began flashing intermittently service axle locker system on and off. Had to drive it home this way with the alert flashing on ans off. Got into driveway and differential tried to lock itself in my driveway while backing and filling into garage. This is dangerous. If differential locks at 70mph on freeway or going down step winding road unexpectedly fear this could cause an accident. At dealer now. Replaced rear axle assembly. Still broken, throwing codes, dealer trying other things. Please know not isolated situation. Many Wrangler owners from 2018 to 2021 posting this up.
