Red Triangle in Left Mirrror

Can some one help?
Started out so intermittently every once and awhile....
Now while driving, signalling left in either single or double(left or right lane) or triple lanes the left mirror lights up a red triangle and there is an audible noise from inside. There is nothing there in the blind spot, on the left or behind us. This does not happen signalling right.
Thanks

Your blind spot sensor is acting up, probably water got into it. Some dealership they offer good will repair, if your dealership don't offer that, you are looking for 2k repair bills.(Sensor $800 CAD each + wiring $300). Do a search on forum, you will find a lot of information

Just buy a sensor form a snow free area like Australia.

Our sensors never seem to fail.
