My 2015 JKU has 35's and had a lightbar, I didn't notice a change in gas mileage but the noise was horrible.....while trying ideas to fix this my son took it on a trip and the vibration going down a windy freeway at 65mph vibrated the threadlocked bolts out and it came loose on one side! Looked...
So I have a weird issue. The key that has been in the ignition will not lock doors or unlock. The spare key will work fine. We changed batteries in both fobs and disconnected the battery to reset. The only other thing is it usually says that the key is in ignition even when its been removed...
