I own 2 Acura with this feature: a 2014 MDX and a 2015 TLX. But both behave quite differently. The MDX seems to be very reliable and comes on whenever a car comes in your blind spot and very rarely comes on for no apparent good reason. On the other hand, the TLX gives me a lot of false positive, in other works very often it will light when there are no cars in your blind spot; sometimes I thing lamp post sets it off. Are the sensor different or is it just the programming? Has anyone experienced the same issue? Any ideas?
