2008 Jeep Wrangler exterior lighting 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!”

“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.”

“VEHICLE COMPONENTS BEGIN MALFUNCTIONING, WIPERS TURN ON, WIPER WASHER PUMP FLOODS WINDSHIELD, LIGHTS FLASH, HEADLIGHTS RANDOMLY TURN OFF WHILE VEHICLE IS IN MOTION, HORN SOUNDS, CANNOT TURN VEHICLE OFF. TURN KEY TO OFF POSITION AND VEHICLE CONTINUES TO RUN CREATING AN EXTREMELY DANGEROUS SITUATION. WIPERS AND WASHERS BLIND DRIVER RANDOMLY. ONLINE RESEARCH ALL POINTS TO KNOWN ISSUE WITH TOTALLY INTEGRATED POWER MODULE THAT HAS WELL DOCUMENTED FAILURE RATE. THIS IS A HORRIBLY DANGEROUS SITUATION THAT DESERVES INVESTIGATION AND REMEDIATION.”

“THE HORN BLOWS ON ITS ON, THE WIPERS AND WASHERS COME ON BY THERE SELF, LIGHTS COME ON BY THERE SELF, AND THE ONLY WAY TO TURN THEM OFF IS DISCONNECT THE BATTERY. IT HAPPENS MOVING OR STATIONARY.”

“2008 JEEP WRANGLER HAS HAD SEVERAL ISSUES WITH TIPM. WIPERS WILL COME ON, HORN WILL SOUND, WASHER FLUID SPRAYS, AND TRANSMISSION WILL NOT SHIFT (WHEN THE VEHICLE IS IN MOTION AND THIS HAPPENS) INTERMITTENTLY AND WILL SOMETIMES CREATE A NO CRANK/NO START CONDITION AFTER THE MALFUNCTION HAPPENS WHILE THE VEHICLE IS IN MOTION AND HAS BEEN SHUT OFF. DEFECT HAS BEEN TRACED BACK TO TIPM AND TIPM WAS REPLACED WITH AN AFTERMARKET REMANUFACTURED TIPM. PROBLEM RESOLVED AND NOW HAS REAPPEARED WITH ADDITIONAL SYMPTOMS, SUCH AS WHEN VEHICLE IS PUT IN REVERSE WIPERS WILL GO OFF AND ENGINE WILL REV TO HIGHER RPMS THAN NECESSARY TO ALLOW FOR ACCELERATION. THE TIPM DEFECT CREATES A SIGNIFICANT SAFETY HAZARD WHEN IT INTERFERES WITH THE SHIFTING, ACCELERATION OF VEHICLE. MOST RECENT ISSUE WAS 11/09/2020; ISSUE HAS BEEN ONGOING SINCE 06/2019.”

“WE WERE DRIVING IN THE NM MOUNTAINS AT NIGHT. THE HEADLIGHTS AND TAIL LIGHTS WENT OUT. THE WIPERS STARTED RUNNING. I PULLED OFF THE ROAD. WE WERE LUCKY WE DIDN'T HAVE A WRECK. EVENTUALLY WE SHUT OFF THE ENGINE AND RESTARTED IT. THE LIGHTS CAME BACK ON.”
