Death Wobble documented on JL too — despite revised steering geometry vs JK. Less frequent than the predecessor, but NHTSA complaints on record. Causes identical: tie rods, damper, wheel bearings.
Welded seams on the floor and sills let water in during rain or washing. JL-specific issue from revised body construction.
A/C loses refrigerant through leaking lines — condenser and line fittings damaged in rough off-road operation.
Start-stop system deactivates unexpectedly or prevents engine start — software fault or AGM battery wear. Known JL issue.
