2001 Mitsubishi Montero Sport electrical system problems

“THIS WEEK I HAVE HAD TWO OCCURRENCES WHERE THE HORN JUST STARTS BLARING AND WON'T STOP. ONCE WAS IN THE AFTERNOON, AND THE OTHER WAS AT 5:00 AM. MY ONLY DIY ALTERNATIVES ARE TO DISCONNECT THE BATTERY (OBVIOUSLY CAN'T USE THE VEHICLE), OR REMOVE THE FUSE (VERY UNSAFE). THE VEHICLE WAS STATIONARY, NO WEATHER PROBLEMS, TEMPERATURE WAS MILD (AROUND 70 DEGREES). PRIOR TO THIS HAPPENING, THE HORN RARELY WORKED AT ALL; AT LEAST NOT WHEN I WANTED IT TO WORK. I GOOGLED THE PROBLEM AND IT APPEAR TO BE VERY WIDESPREAD ON THIS VEHICLE. FROM WHAT I HAVE FOUND OUT, IT INVOLVES REMOVING THE AIRBAG ASSEMBLY, SO GETTING IT FIXED IS VERY COSTLY (OVER $1000). I EXPECT TO SPEND SOME MONEY ON A FEW ITEMS HERE & THERE ON A 16 YEAR OLD VEHICLE, BUT I DON'T EXPECT TO SPEND OVER $ 1000 ON A VEHICLE JUST TO MAKE THE HORN WORK RIGHT.”

“TL* THE CONTACT OWNS A 2001 MITSUBISHI MONTERO. THE CONTACT STATED THAT THE HORN SOUNDED INDEPENDENTLY. THE CONTACT STATED THAT THE BATTERY HAD TO BE DISABLED TO STOP THE HORN FROM SOUNDING. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 150,000.”

“TL* THE CONTACT OWNS A 2001 MITSUBISHI MONTERO. WHILE DRIVING 65 MPH, THE HORN SOUNDED LOUDLY WITHOUT WARNING. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE HORN FAILED AND THE HORN MODULE NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 352,478. MA 10/15/2015”

“I HAVE HAD AN ISSUE WITH MY TRUCK BECAUSE THE HORN QUIT WORKING SEVERAL YEARS AGO. I WAS TOLD BY THE DEALER MULTIPLE TIMES THAT THE AIRBAG HAS A METAL RING INSIDE OF IT THAT MAKES CONTACT TO ACTIVATE THE HORN WHEN PRESSED. THEY CLAIMED THE RING HAS EITHER DETERIORATED OR BROKEN INTERNALLY AND THAT IS WHY THE HORN DOESN'T WORK AND IS A VERY COMMON ISSUE FOR YEARS WITH THESE TRUCKS. BASED ON THE CURRENT RECALLS I AM WONDERING IF THAT ALSO EFFECTS THE AIRBAGS AND IF THEY WILL WORK PROPERLY OR IF THERE COULD BE METAL SHARDS IN THERE THAT WHEN DEPLOYED COULD POSE A SAFETY ISSUE. *TR”

“RANDOMLY THE FACTORY ALARM GOES OFF THROUGHOUT THE DAY WITH THE HORN BLARING. AFTER A WHILE, THE ALARM DRAINS THE BATTERY, EVEN IF IT RESETS. FUSES HAVE BEEN CHANGED, RELAYS, AND A RESET BY DISCONNECTING THE BATTERY- TO NO AVAIL. *TR”

“THE HORN RANDOMLY STARTS BLARING IN THE MIDDLE OF THE NIGHT IF YOU DO NOT REMOVE THE FUSE. IF YOU REMOVE THE FUSE IT LEAVES YOU WITH NO HORN! COMPLETELY UNSAFE WHEN DRIVING NOT TO HAVE A HORN. CLEARLY THIS DEFECT WAS NEVER CORRECTED BY THE MANUFACTURER. AFTER LOOKING FOR A CAUSE IN MANY FORUMS, IT IS CLEAR NO ONE IS CERTAIN OF THE ACTUAL CAUSE. *TR”
