False Collision detection alerts at stop lights

[leecm]

Does anyone else have this problem? My 2019 GT2 sporadically gets false collision detection alerts at stop lights when I'm a normal distance behind a car. Usually it's just the yellow warning, but I've had a couple of instances where it was the red warning. If so, does anyone know what causes it? Is there any way to fix it?

I guess one positive is that it encourages me to sit further back from the car in front of me.

I rarely get a beep, yellow (don't remember ever getting a red except when a pedestrian walks too close to me). And it has been surmised that surrounding vehicles with their own electronic gadgetry are interfering. Other than annoying, I don't believe that this quirk signifies anything heading south; all is as it should be.

I've had the sensors go off a few times when I wasn't near anything that I could see. Maybe the sensors picked up something very small. Sometimes the sensors don't pick up anything when I'm very close to something. Electronics can be quirky.

It’s warning of imminent collision with a fly.

Occasionally. Probably a handful of times in 14 months.

I'm more irritated by the front sensors yelling at me when backing out of a parking space, like my garage.

Just curious, you mean FCA/FCW instead of parking sensors right? Because I had parking sensors magically re-activate when I was kinda close to a vehicle's quarter panel at a stop light (yes I was driving over 12.4 MPH per the manual).

It sometimes occurs for me when I am behind a ford/lincoln/mercury crossover or some bmw vehicles.

It's the other vehicles parking sensors interacting with yours. The sensors emit a pulse and look for reflection, but sometimes it will lineup with transmitted pulse from the car in front. Usually its just a quick beeping before they desynch. It only happens when the vehicle in front has similar parking sensors also.

Happens to me all the time
