On multiple occasions, the horn itself will start blowing without command. After pressing the horn to alert another driver, the horn will then stick again. There are repairs where 3m tape is applied to the horn switch behind the airbag, however it is not a professional repair and looks like it could potentially cause the horn to blow without command again.

What 2001 Mitsubishi Montero Sport owners say
Most recent owner complaints, unedited.
4 wh drive light flashes no apparent reason no issues makes the anti lock light come on and also the abs light worried cause a prob wit the brakes or something
Brake lines completely rusted through and I lost all brakes while heading to work, thankfully I was able to pull the emergency brake to slow down and I coasted through a red light blowing my horn so I was not hit. I bought this vehicle brand new with only 3 miles on it and ever since I initially got it , it began to rust. Clearly it was not rust treated as everything under the body and alot under the hood is rusted. There is even metal inside of the vehicle cabin that is rusted, like the gas cap lever. This vehicle should have been recalled many years ago like the Outlander due to all of the rust the vehicle gets under it causing thing to fail while its being driven. My vehicle just has a little over 100,000 miles on it and it now sits after that brake incident as I am afraid to drive it seeing all of the rust under it. Even the running boards are all rusted underneath. I am sure that everyone with this model vehicle has experienced the same problem but these vehicles are dangerous on the roads due to everything on them rusting .
I drove my family to their doctor app. And when I was parked gasoline was dripping down in front of the drivers rear tire onto the pavement upon inspection I saw gasoline running off of the top of the gas tank I then went and told the parking lot attendant what was happening he then had to blockade that area of the parking lot off. I had call to get us a ride home . I had my vehicle towed home and had a mechanic inspect it and he found the steel gas lines were completely rusted thru on the pressure side and the return line as well upon further inspection he found severe frame rot and said it won't pass inspection when it comes due next time.
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.
Frame is rusting to a point where it's becoming unsafe to drive. While driving the car tends to shift back and forth in the rear. A service representative pointed out the almost rusted through frame near the drivers side rear wheel.
Tl* the contact owns a 2001 mitsubishi montero sport. The contact heard a squeaking noise coming from the steering pump pulley when the vehicle was started. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was unknown.
Lost control of vehicle and proceeded to drive onto shoulder. After checking I noticed the frame had ripped ,broken off. The passenger side frame was completely rotted for 3-4 feet. From the front door to the rear wheel . After inspection of the entire frame the driver side is unaffected which leads me to believe it is poor metal/frame from the factory,no anty corrosion was apply to the metal frame from mitsubishi factory.[xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
While driving on the highway. I lost control of vehicle and proceeded to drive onto shoulder. After quickly checking tires, etc. I noticed the frame had ripped in half.
