“2002 Mitsubishi Montero Sport. The horn sounds for no reason, when the temperature drops below 55degrees. I must remove the fuse to silence it. It is state required safety equipment. I contacted the lancaster, pa Mitsubishi dealer but they won't reply. The problem started in the winter when the temperature dropped below 18 degrees. It is 8 months later and a cold august night triggered it.”
NHTSA complaint #10421099, filed 2011-08, 82,000 miles“During cold weather (approximately 20 degrees c and below) the horn starts blowing and won't turn off unless the battery is disconnected or the car interior has warmed up. The only way I have to prevent the horn from coming on is to keep the horn/air/bag assembly warm. I wrap an electric blanket around the steering wheel.”
NHTSA complaint #10181825, filed 2007-02, 69,108 miles“2002 Mitsubishi Montero Sport; the car horn/alarm goes off usually when a drop of temperature occurs in the middle of the night. To fix ... Has something to do with a short in the electrical of the air bag and the steering wheel column. Very expensive for a mechanic, over $1200. I have to unhook my battery every night and on colder days. Researching online.....a lot of people are disabling the horn/alarm system and driving without horns. Or they are tampering with the air bag to try and fix. It is a very common problem....... …”
NHTSA complaint #10556927, filed 2013-12, 125,000 miles“Horn button when the accessory socket is in use or not in use,the horn continues to blow when the button is released. Therefore the fuse to the horn must be disconnected at all times. I had it put on a diagnostic machine and in order to have this fixed it will cost $1300 because the problem has to do with the air bag. If it were the relay switch it would have been $24. This is not from what I think is something that consumers must pay for. I live in the state of virginia where it is required to have vehicle safety inspection done every year and the first thing that's checked is the horn. …”
NHTSA complaint #10312616, filed 2010-02, 89,000 miles“Dealership said there is sludge in engine due to lack of proper maintenance . We've had the oil changed according to the manual but believe that the oil pan is positioned wrong as the dealerships told us that about 1/4 inch to 1/2 inch is always left in the bottom of the oil pan when you change the oil, therefore creating sludge. The oil pump has also gone bad on this 2002 Mitsubishi Montero Sport, with 62,000 miles. No one will pick up the bill, even though we paid for an extended warranty. We've also put three alternators on it in one month and had the cam seals replaced. …”
