Hi guys

I am wondering if the freezing cold can affect the parking sensors plus the boot lock mechanism?  I have got a Ford Fiesta 2011 model which has got some rear parking sensors on it..  They were find yesterday but now for some reason when I put the car into reverse it beeps once (like normal) and then a continuous beep even though there is nothing behind it at all.

Also the Boot is very hard to open in the morning.. Plus sometimes while driving the boot sensor says that the boot has come open..

 

No idea if both things are affected by the freezing cold or this is more of a serious problem

Hi had the same problem with mine when not cleared all the snow from back bumper,

also if if there is any paint blisters , srape off with finger nail and problem went away !

When I started my car this morning in a temperature of -4, it sounded like the big ends had gone.   Was OK after a couple of minutes driving though.

 

Wayer can get into the sensor housing, and when it freezes it becomes a solid item which the sensors interpret as you hitting a wall.  With luck it should clear come the thaw...with luck.

Yeah I think there is ice completely in the whole sensor section.. Have to wait until the weather warms up and hopefully that will sort out the issue :)
