High beams will not activate while car is in "auto headlamp" mode. If you toggle the high beam stalk nothing happens. I have to physically hold the high beam stalk down for the lamps to work while in "auto" mode. If I want to use the high beams without holding the stalk down I have to switch the headlamps to the "on" position using the headlamp control switch. Using my hand to hold down the stalk in order to access my high beams is a huge safety hazard requiring me to have only one hand on the steering wheel. Switching the headlamp mode to auto to access my high beams is more hazardous as I have to take my eyes off the road to find the control switch. There is no "automatic high beam" mode available through my vehicles on board options. This has been an issue since I purchased the vehicle new. Unfortunately weighing my options I an unable to use the high beams because it is too much of a hassle to do so. I thought this issue was recalled but after speaking with Jeep and my dealership I was told otherwise.
High beam headlights don't work when the headlight switch is in auto mode. Problem has been confirmed with bozak motors in merrillville and they advised that there is a bulletin out advising them not to attempt repair as engineers are working on issue. Further research on my own reveled that they have 3 other of the same vehicles on lot with same issue. Seems like a safety issue when driving at night down country roads.
