2008 Jeep Wrangler electrical system problems

“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 haywire and would not shut off, even with key out, and battery disconnected!”

“The ABS computer brake module is bad in my jeep. It needs a replacement. Confirmed by Chrysler Jeep dealership. However, Chrysler does not offer a replacement module. ABS does not work on my vehicle. This is a huge safety issue and is common problem among this year Jeep. Chrysler shouldn’t be allowed to NOT have a replacement OEM ABS module. Huge safety risk and lawsuit”

“I was driving down the road in my 2008 wrangler and all of the sudden every light flashed on my dash board then it felt like I could not shift gears then smoke came pouring out of my air vents. I pulled over and got out realizing it was on fire. Climbed in to save my dog just before the fire got huge. My entire Jeep is gone.”

“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 is still at the dealer (Crown Chrysler Jeep Dodge Ram Dublin, OH). Losing power precipitously presents a safety hazard.”

“Headlights stopped working. The Headlights are controlled by a computer. No relay, fuse, or anything that can be fixed at a parts store. We had to wait days for a computer to show up.”

“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.”
