I would certainly have it replaced, because if it's operating in an "implausible" regime now, it'll get worse later. It could be a loose connector, or it could just be a defect in the sensor, such as a funky deposition on the antenna array or an intermittently-bad power amplifier. I definitely wouldn't just let it sit there and have to work around the car to get things to work properly. You didn't buy a Tesla after all.
I don't believe that the radar sensor is defective based on a number of observations and talking with the lead tech. I can stop the issue if I also turn off the headlight animations. The problem is too much voltage drop due to everything starting at once. The software change which was applied reduced the issue to only once out of 20 starts. MB needs to revise the latest software enables enterprise for the sensors to have a bit more delay. BTW, the control module and sensor are one unit. There's no guarantee that a replacement unit won't develop the same issue. I'm not interested in a front end teardown to replace a small part. The engineer in me can't deal with the potential end result of misaligned bumper/fender and potential loose panels.

The service dept has opened a technical case for the condition. Meanwhile, I'm not interested in the frontal lobotomy of my new car in order to address this annoying issue.
I have had frontal, interior, and posterior lobotomy for three different issues in the first 3 months of ownership. Everything was put back together perfectly with no scratches, misalignments, or rattles. The car has been solid for the last five months.
Seems like low risk for good reward, but it is you cal if you can live with the issue.

Thanks for your reply. The radar sensor is only showing an initialization issue and no other errors. I understand from my tech that there could be another software update as the initialization issues have been occurring on other vehicles in addition to the EQE. Otherwise, the car is functioning extremely well and I'm most pleased with the ride quality and handling. I especially like not spending over $130 / month on gas anymore!
I am seeing similar issues with my EQE SUV. I took it to the dealer and they said the software update should fix the issue. Two days later I had the same issue at start of the car. Now planning to take it back to service to diagnose again. Not thrilled about this as I had a Tesla with sensor issues before this. Hoping this time I won't end up having to give the car back, as I enjoy the car so far except for this issue.

I'd insist on having the faulting sensor replaced. This is not normal vehicle behavior. Never had this happen once on either of our cars, or on my dad's. Faulty sensors do happen. I'm not sure who makes these particular radar sensors, whether Continental Teves, Valeo, etc., but there may be a bad batch floating around there.

It's software sequencing. Sensors see marginal voltage and fault.

Ask which sensor is giving the failure code. I bet it's the left front sensor. Post back.

Finally got the car to service, the service rep said there is a known "Glitch" in the battery module. And have a software update to fix it. He also said that it's not common but they have seen a few cars with this issue. Let me see if this issue goes away. Software update details

There is no 48v battery in the AMG EQEX4. My errors have not reappeared, but I don't start the car with my foot on the brake the first time. I let everything settle down before I depress the start button with my foot on the brake the second time.
