Horn going off whilst driving

[SimonMG5]

On my last drive of about 20mins the horn just randomly went 3 or 4 times whislt driving, hands no where near the horn - anyone had this?

Short answer: No!

Which version of the MG5 do you have, pre-facelift or facelift?

 

[Black estate]

Me neither

facelift

I think someone else had a similar issue to do with the horn or buttons on the steering wheel.

Their problem was the cable inside the steering wheel.

It is quite complex because that cable has to be able to expand and contract as you turn the wheel full lock either way.

If the issue keeps happening you might need to get something replaced behind the wheel.

Certainly sounds like a fault so one to refer to your dealer although that may be problematic if the symptoms are not repeatable.

I had it once,... found i was sitting on the keys which was setting the horn off!

Second this, i was driving down a country road and the bumps were enough for me to be pressing the remote button in my pocket and sounding the horn. I leave the keys in the cup holder now.

Yes! At first I thought I was imagining it but it happened 3 or 4 times. It hasn't happened since.

Same issue with pressing key button in trouser pockets, just put your keys somewhere unlikely to be pressed

Mine happens most mornings when I bend over to put my boots on and the fob presses against my phone.

Neighbours don't need sleep, right?

My horn blows when I'm turning right.

OMG - that's a blast from the past (literally) - you've just taken me back about 40 (cough... maybe 50) years. My parents had an original Opel Manta and it also started hooting when they turned the wheel. Turned out to be part of the horn switch's contact (larger metal plate) within the steering wheel which had delaminated and contacted the other plate, closing the circuit and making the horn sound. Not sure if steering wheel horn switches are so mechanical these days, though!

Yes! Had the same with a VW Polo ~30years ago.
