Parking sensors going off in stop and go traffic

[kitkat]

Yeah I don't think this is a pointed wrong issue on my car.

 

[virtualmacho]

Which ones are we talking about? The "corner" sensors (boxed in green) or the "front" sensors (circled in red) ?

Well, the plot thickens. While reading the manual, I noticed there is another area highlighted as having radar aside from the visible circular sensors, and it does note that PPF can affect it (on a previous page). Note the red area on the left and right of the bumper here. I thought this was just a control unit or module, but then I noticed it says to keep it clean. Any ideas if this combined with PPF could be an issue?

On all US cars so far (first edition) there is nothing there. I know the area you’re talking about and the bumper has a recess for it but there’s no module present. Many of us put the Miltek valve controller module in that spot.

I have been having front driver side sensor issues since day 1 (dealer tried to address it during delivery via a full round of software updates unsuccessfully). It is something I learned to live with (for now) by disabling parking sensor after backing out of my driveway (the icon is available on backup camera display) but would be great if they fixed it once and for all. Given that this is a same sensor for many of us I would image this is a software issue rather than a hardware issue (unless something next to that sensor in the bumper is triggering it via radio interference?)

For me, it's always seems to be the far right sensor giving false positives. Maybe it's not a problem with the software, as I suspected, b/c this probably would be happening on the left side, as well.

My memory may be suspect, but I don't ever remember seeing this on the far left side sensor. Will keep monitoring.

False positives have always been on the front left for me, so if we are running the same software, the probability of a hardware issue would be higher. No way for the end user to confirm the software level, so we're all just guessing...

Has anyone tried some sort of vibration damping in the vicinity of the sensors? If there is a vibration close to the operating frequency (50-60Hz ?) it may be causing the sensors to go off.

My Emira has the same issue since day 1. The driver side front sensor beeps on red (the "closest" reading) whenever I stop in traffic or on lights (once every 5 stops or so). Took it to the service center and they fully replaced all the sensors of the car and updated the software... and it's still happening albeit not as often (once every 30 stops or so)
Also, it used to do a full beep for 4 or 5 seconds but now it does a small instant one (less than a second), and I still need to wait for the graphic to auto dismiss.
I'm considering this issue fixed since it rarely ever happens anymore but I'm pretty confident it's a software problem since after replacing all sensors it's the same exact issue with the same exact sensor. I have also noticed a weird new behavior that every single time I pull out of my garage that same sensor beeps maybe half a beep long enough to show the graphic but not long enough to show the red mark of thr sensor on the graphic. Not sure what this is about but it happens every single time. It's usually ok cz that's only once a day as I'm leaving to work. During regular driving though it's very rare now.
Also for what it's worth, the service center told me they've had a lot of the same issue reported and Lotus is aware, didn't give more details.
Otherwise the car is amazing and driving it is a joy, so I'm willing to forgive this as it's the only issue and is happening pretty rarely after the fix.
Hope this helps others!

Oddly, so far, I haven't experienced a false trigger of the proximity sensors on my Emira, but it has occurred occasionally, albeit very infrequently, with my 911.

Mine does it randomly as well when stopped at a stoplight. Sensor on the left front.

Anyone experience their parking sensors going off in stop and go traffic? For me it's always the LHD driver front sensor that triggers. It doesn't happen all the time, but happens enough to be slightly annoying. I believe it's detecting a car in the front because it has happened with no car on my left. Ironically, the last Honda Odyssey I owned also had a similar issue, but in that case, it was completely phantom - I could be sitting by myself in a large empty lot and it would beep at me. I largely lived with it because it's impossible to replicate reliably.

Same here, LHD location but only occasionally. Bordering on being annoying though, will mention to dealer when I bring in for service.

I have this same issue. The dealer recently replaced the front left sensor and it did not fix the issue. They now have the right sensor on order to replace it, if that doesn't work, they said they are going to have to call Lotus to troubleshoot the issue. I don't think its the sensors for whatever that is worth.

Do you have a front plate? My Land Rover did that all the time until I removed the plate; wasn’t even near the sensor but can’t be a coincidence.

No, I don't have a front plate or any type of plate mount up front.

Front left ghost sensor here as well - annoying but maybe I'll mention it on my next service.

I also have this issue with it being the front drivers side sensor.

 

[Eagle7]

Since others have had the front sensors completely replaced, and they're still having the issue, I'm wondering if there might be some corrosion in the electrical connector from the wiring harness. I'd check both there and at the fusebox to see if somehow moisture got in there and the connectors are either corroded or oxidized.

Front driver ghost sensor here very often, particularly annoying.

Am I the only one that has the ghost on the passenger side?
