Random vent lights going out and traffic sign assist inoperable.

No idea but a trip to the dealer is in order, take your pics as proof.

jerseya220

Indeed. Especially since I picked the car up 1 week ago.

Traffic sign inoperative is common for me. Almost every time I remote start the car. I haven't had LED problems though.

jerseya220

Any idea why it happens to you? I know my view was unobstructed and the windshield clean?

I asked Mercedes about it and they said to bring it in. Appointment setup for tomorrow AM for them to try to figure out why the lights are going on and off and take a look at the traffic sign issue.

Deriggs007

Did you remote start the car? But yes, frost, dirt etc can cause it. I've only noticed on remote starts.
The lights should not happen. You need to take it in for that. In fact, take it in for both of those. Mine shouldn't do it either, but I haven't taken it in yet for the sign recognition

jerseya220

If I remember correctly I did remote start the car. It has happened several times. Agreed, the lights should definitely not happen, even if it sporadic. I guess it's a bad sign that I've had the car almost two weeks and I'm already frustrated with it.

aaaand they are saying there is nothing they can do about either problem. Sounds like a load of crap to me.

Go to another dealer? The traffic sign issue, is that consistent? I've had something similar to that related to a camera. The vent light issue should definitely not be happening though.

Dealerships in my area have a 2.5 rating for service, I found this Mercedes shop that has a 4.5, the difference is amazing, of course that's for non-warranty work.

The issue is somewhat inconsistent but it has happened numerous times in the last week, under varying conditions. My service advisor said he going to do some digging but at worst I am going to keep bugging them until this gets fixed. There is no reason I should just accept lights randomly not working.

Does anyone know the proper email address for Mercedes Customer Service?

jerseya220

After I pushed back on the service department and demanded they take another look at the car they discovered that the controllers for the Traffic Sign Detection Camera and the Ambient lights needed software updates. Hopefully, that will resolve the issue. We will see.

Don’t let them pull you around. Clearly it has issues and needs addressed.

Pretty sure you can just tell them. “ How can my lights going out be a normal, unsupported warranty fix. Either fix it, or I’ll demand a buy back and let mercedes know how you’re treating it’s customers”

the good thing about having Mercedes on your side with horse **** dealerships is that they can refuse inventory deliveries for lack of performance. They don’t want that

jerseya220

Thanks. That is basically what I did now...twice. They told me the issues were fixed yesterday. I picked the car up and within 1 hour the Traffic Sign Detection error was back when I started it up. I drove right back to the dealership and showed it to them. Car is still in the shop

Deriggs007

Mine does it every time I remote start. I have not had the issue anytime I have done a normal start of the vehicle. That more than likely is a software problem.

jerseya220

Yeah I am thinking the same. However, at the cost of these cars they need to resolve it. I should not have to live with dismissing an interstitial error message whenever I start my car remotely. Especially since it is specific callout to a malfunctioning traffic sign detection system.

Deriggs007

Keep taking it back. Every time you take it back and the techs diagnose it. They get paid by Mercedes. So the more we take the car in for problems like this, the quicker they are for an official fix.

jerseya220

Picked the car up this morning and the error message has not recurred. I have tested using remote start and it does not recur then either. They ran an update to MBUX on it that seems to have had a fix for this issue listed as part of the update. Will let you know if the error happens again. Fingers crossed it does not.

Deriggs007

can you provide your software version? Want to make sure mine is same as yours

jerseya220

Never mind, the error happened again this morning. This is getting ridiculous. Back to the shop it will go for the third time.

jerseya220

aaaannnndddd the ambient light issue has recurred as well. This time the passenger side door and the passenger side vent. So much for German engineering!

Deriggs007

That sucks.

Take it in again, get to your 3 times a charm mark and buy back .

Kenyon1976

More bells and whistles, more that can be wrong. My A.I. has been acting weird, interrupts conversations even without the "Mercedes" prompt. It's also said a few very unusual things, had a witness to one, either pranking or an easter egg?

jerseya220

Update: It looks like they have finally fixed both the light issue and the traffic camera recognition issue. In doing so they had to replace a ton of components (including the lights). Let's see how this goes. In total 22 days in the shop in about 45 days of ownership. Not an awesome start. I am still waiting on Mercedes to tell me whether they will buyback the car.
