   While driving at speed, vehicle electrical went haywire. Headlights went on and off. Horn sounding on and off, Wipers and washers going on and off, HVAC blower on and off. Pulled over vehicle and turned off and removed key and it still remained running, all horn, lights, and wipers still going on and off. Opened hood, removed negative battery terminal, and with that, car still ran! Was several minutes and car finally shut itself off. Scary that the car went completely…

   April 22, 2025 my 2008 Jeep lost power. There was a sequence, where one warning light was followed by another, followed by a complete loss of power. I charged the battery, car started up, I drove to dealer (a 5-minute trip), and by my arrival the Jeep had again lost all power. Dealer checked the vehicle, and told me the battery and charging system were fine, but the ABS brake modulator was draining the power. They have not been able to get another modulator and the vehicle…

   The TIPM shorts out then the wipers, start running, horn blares, windshield washer fluid sprays, lights flash. The only way to stop it is unhook the battery. This is so unsafe driving on the highway you cant see the road. I almost crashed trying to pull over. After doing some internet research this is so common. This should be a recall it is dangerous! I wont let my son drive it now.

    This has happened on more than 1 occasion. Driving on the highway and I lose power, the Jeep slows way down, the accelerator pedal is dead, and the Electronic Throttle Control (ETC) light comes on. It does the same thing driving in town. Sometimes you can turn the vehicle off, wait a couple minutes, start it back up and it will be ok for a little bit. Sometimes it won’t. I have replaced some parts, read forums, communicated with a dealer service department and it doesn’t…
