Hi
have 2010 ix35 and have few months. It lately over passed week the alarm goes off for no reason . Any ideas how to fix this
cheers

 

Make sure all the doors, hatch and hood are closed properly. It's possible one of them is not closed all the way and the switch isn't fully closed.

 

My Accent’s alarm kept going off at the slightest noice like bikes and free-flows etc. This drove me mad since I moved to a new house with a speed bump right in front.
I took it in, tried everything but finally found the issue myself.
The motion sensor in the car is mounted on a little bracket.
If the bracket isn’t tightened properly it vibrates in the car setting the alarm off!
Mine was tightened but the flat pin that swivels the motion sensor was loose. Tightened it two days ago. Working like a charm.

 

Had my 2010 ix35 for 10 years and intermittently the alarm goes off for no apparent reason. Can happen in wind or no wind, on the flat or on a slope. Happened twice last night at 4 am and 7 am. Very annoying fir both me and the neighbours

 

turned out my alarm screw was just rattled a tad loose so went off when it rattles (thunder etc). Tightened it and its all good now.
