Parking sensor alert while at complete stop

these cars talk to each other. mostly newer Ford pickups chat with my 2015 sedan at red lights

This has already been covered in several threads here. Probably due to interference from other cars around you with proximity sensors. For me it seems to be mostly Teslas.

If you find it hard to believe that most car manufacturers are using the same technology (and possibly the same parts from the same supplier), then I doubt that I could do anything to persuade you otherwise.
It's a limited case problem that started when some manufacturers (possibly unexpectedly) started leaving their rear facing backup sensors powered even when they were moving f

I do not find it hard to believe that various car makers source parts or systems from a single manufacturer. What I find hard to believe is that the car makers would not have designed & manufactured their cars to avoid this interference.

They give off an ultrasonic signal that reflects back from an object. When another sensor is giving off the same signal it perceives it as bouncing back and reacts. Simple and works well when parking.

They can't figure out 5G cell phone towers and aircraft altimeters either.

If you have a solution for either, Genesis and Boeing would like to hear from you.

Other than the dealer, do you have a source for this information, specifically the cause? I find it hard to believe that sophisticated modern cars would have this problem. I had a 2008 Toyota with front & back parking sensors, never a problem. Did the technology get worse over 11 years (I have 2019 G90)? It doesn't make sense for any car maker to design and build a car without planning around other vehicles using the same technology. My dealer told me what you are telling me and I just don't buy it. I really think something is wrong. So if you have any supporting information I would greatly appreciate it. Thanks.

Possible your Toyota had electromagnetic sensors that are not as good as ultrasonic. Think about the logic of how ultrasonic works and you will understand why the get signals from another nearby. The price of a better sensor.

My Toyota had ultrasonic sensors. I know how ultrasonic systems work. I still find it hard to believe that a $50,000 car can't tell the difference between another car's ultrasonic sensors and an actual obstruction. If the gain or other filter parameters were adjustable perhaps the interference could be tuned out. Just because the dealer says it doesn't make it true.

I’m appointing you to contact your dealer to resolve this question and advise us. Are you up to this task?

A) It 's a new federal regulation. Cars are now required to practice social distancing. As long as you stay apart by +6ft the false alerts should be minimized/eliminated.
B) Cars are now communicating with each other, planning to takeover the world (Skynet v1.0).


I rarely get these false alerts because I don't crawl up the "arse" of the car in front of me at a red light. It's a driving habit I've been doing for years.
1) If I get rammed in the rear it will prevent/reduce damage to the front end of my car.
2) If the car in front of me doesn't move (breaks down, driver has a heart attack, drive talking on a cell phone, etc.) or a carjacking attempt, I can easily pull around them without having to back up.

Also,
Regularly clean the sensors removing dirt/bugs. This will affect the functionality of the system.
I've also experience these systems malfunctioning during heavy rain or snow/ice/slush accumulating on the sensors.

I've asked my dealer and their answer simply doesn't make sense. I maintain that a $50,000 car should be able to tell the difference between another car's ultrasonic transmission and an actual object. I will continue my discussion with the dealer and keep everyone posted. Thanks

As an electrical engineer, the explanation makes perfect sense to me. I suspect that the real change now is that there are so many cars now with the sensors, and so many are leaving them powered all the time now. Until the last few years, it was rare to see parking sensors on most cars, and when you did, it was usually only on the rear. It seems that the cars with rear only sensors, are more likely to have them powered down when not in reverse.

My 2006 Lincoln had rear sensors only, and it had both ultrasonic (for close up) and radar. Since it had radar, it could warn about things that were several yards away. Of course, this added distance wasn't really that useful. I never got any false forward alerts simply because it had no forward sensors.

Great explanation. Makes perfect sense and doesn’t surprise me.

You'll probably not feel any better but it is not just the $50,000 car, the $85,000 ones have the same issue.

Yeah - I looked back and my car new was more like $75k. I am still not satisfied with this concept. I understand the physics perfectly well. I will continue to research. Thanks.

yet another example of a simple software fix that could provide a little less annoyance. these are really adding up with genesis. other brands lower the volume of their parking sensor alerts if the vehicle has been stopped and the sensors are alerting more than about 3 seconds. by doing this, you still get the annoyance, but its not as loud as your preset volume. some manufacturers even disable the alerting if the car is in gear but stopped more than 3-5 seconds and just display the visual on the dash gauges! something genesis should implement!

Light2000, clearly you have not been indoctrinated by this thread properly. The type of thinking displayed in your comment indicates that you are not a sheep. How dare you use logic instead of blindly accepting what the all-knowing dealership says as the gospel? Where do you get off? From your comments I can tell already that you are a trouble maker who tries to think for himself as opposed to a good boy who stays quiet in the face of adversity. I'd hate to be your service manager at the Genesis dealership. Clearly the worst kind of customer.

What are the other software issues?

Update for everyone on this thread: My dealer said the mother company from S Korea acknowledged the parking sensor malfunction as not performing as designed or intended and is working on a fix. In other words, simply accepting the false positives as an unfixable result of interference from other cars' sensors may be acceptable for you but not for Genesis nor for me.
