Front Ultrasonic Sensor Fault

[lucidtouringman]

While using Automatic Cruise Control today on the road going about 40 mph, the car in front of me slowed down to make a left turn. No big deal I think and the car slows down by itself as intended...but then suddenly a fault pops up saying Front Ultrasonic Sensor not working, try cleaning the sensors.

That was around noon earlier today and after numerous hard resets, Air logo resets, Bobby resets and calling customer care, the fault still exists. It's not a critical fault but I'm gonna be on the road for 12hrs tomorrow and would love not to have to deal with this fault. Nothing is physically damaged and I've cleaned the sensors to a squeaky clean including the lidar and radar and anything that throws out a sound or electromagnetic wave ... There was no physical contact of any kind whatsoever....any ideas on what I could do besides take it in for service?

Yes, that happened to me. You will need to take the car to service so they can replace one of the ultrasonic sensors. It is not a big fix but will cause your parking assist and surrounding view not to work until that sensor is replaced.

The issue is with one of your ultrasonic sensors in the front bumper. It is those little circle sensors. Number 5 on pic below.

Thank you.. I figured as much. It's odd though that these sensors can go bad just like that. Oh well...

I just had a similar experience, but Lucid Service says it's not covered under warranty because it's damaged. I've had no accidents and there's no visible damage, but they are saying it might have been a rock chip. Has anyone else had to pay to have it replaced?

Yeah, I paid about $300 or so to get it replaced. Mine had a very clear chip/damage on it though. I recall exactly when it stopped working when I was driving, but I did not hear any rock hit the car. Oh well...they turned it around in like 2 days
