On my way home from work after dark, I experienced a loss of head lights, dash power and heating traveling at a high rate of speed down the interstate. Earlier that morning on my way to work, the dash quit working 4 times. All gauges stop working and drop to zero and the heat/ac quits. I have experienced my head lights turning off/losing power on 3 separate occasions. I am able to switch them from automatic to on and they work. Once my dash "flickers" and returns to normal, the engine light, traction light and esp bas light stay on. This has become a daily malfunction that occurs on my way to and from work. The first time this occurred in September of 2014, I drove straight to auto zone and bought a brand new battery. They tested the battery and said I needed a new one. They installed a new battery and connected power to the Jeep while they changed it. I figured a bad battery was the issue and it was now fixed. A couple days later, I began experiencing a loss power to my dash again. I have taken my Jeep to 3 different Jeep dealerships and they cannot find anything wrong but an ignition switch or bad battery. They all told me that they had not received the ignition switch part for the recall but I will received a notice in the mail when they do. One Jeep dealership contacted auto zone and told them the only thing they could find wrong with it was the battery. I went back to auto zone and they replaced my battery. I have had my alternator checked several times and it tested good. This defect/malfunction is dangerous and a hazard to my life as well as other motorist. I am very dissatisfied with Jeep's handling of the situation and long await period of the recall part.

2006 Jeep Grand Cherokee - all safety warning lights as well as engine lights flash on and off, rpm gauge drops, all lights around gear panel light, doesn't seem to know what gear it is in. Sometimes it is just the lights on the panel flashing on and off. No codes read when taken to mechanic. Put a new batter and alternator in the vehicle. Problem is intermittent. May happen a few times in a row and then go away for days or weeks. Lost power brakes and steering as well a few times, luckily no accidents resulted due to loss of power. You can hear a clicking noise when the panel lights are flickering on and off. This problem has been occurring for the last year and a half. I had a complete transmission service as well.
