Brand new car. Check engine light came on within 24hrs.
I picked up a brand new 2021 GLE350 on Saturday and drove it home. On Sunday took it out for a drive and the check engine light came on. Took it back to the dealership on Monday and they have been running diagnostics all day (can see engine/doors/hood etc. opened and closed via Mercedes Me app) but so far no verdict on the issue. It must be more serious than a gas cap not screwed on properly. Pretty sad and disappointed. I should be focusing on “break in” the car but car is actually “broken”

Got a C300 sedan as a loaner.
Dealership just called and said they need to keep the car for another day to do more diagnostics. Initial verdict is the factory overfilled engine oil and it triggered a sensor when the oil expand when engine got hot or there is a faulty sensor.
I don’t know why they didn’t catch it with the pre-delivery inspection. Aren’t they supposed to check the engine oil??

2023 GLE 450 4matic
My 2020 GLE350 displayed a check engine light at about 250 miles. Took it back to the stealer and they "fixed" something trivial. I don't remember what it was, but it took them a week, When I picked it up, the light came back on before I got home. The second time they had it for almost 2 weeks, waiting for parts. A charcoal canister and some tubing were replaced. It's been totally flawless ever since. I know how you feel, the stealer had it more than I did during the first month of ownership and I was not a happy boy! Thankfully I've not had any other problems and learned to really like this car. Hang in there.

Sorry to hear. If you are able/willing when the vehicle comes back to you, can you please post a copy of the service invoice with your personal information redacted? It will help others with their vehicles.

I have a GLE , however on my daughter’s GLB her CEL went on and she too had to have her charcoal canister and purge valve replaced. It was a big job when reading the bill/ summary of what was done , dropped gas tank , removed muffler, cleaned floor boards and more. Someone at dealership said that she has seen several cars in for the same problem and there may be a service recall.

I don't trust "someone at the dealership said." We have multiple posts like that on many threads, and most don't seem to bear fruit. But they are repeated often by the "usual suspects" who then claim that it's irrefutable proof that M-B's are trash, because they've repeated it so often.
I'd dig deeper if it's my car.

When I referred to “someone at the dealership said “ , this is an individual who sees all the services done on every vehicle. She is in an excellent position to perhaps see any trend of a particular repair. The repair becomes more obvious when it requires 2 days to complete and a loaner car is provided. I was simply reaching out to see if other MB devotees may have experienced the same problem. I don’t see where I claim irrefutably that MB is junk as you mentioned. This is our 5th MB , for me to think that a MB is junk and continue to buy them would truly be an insane thing to do. Perhaps I am not as sensitive about my MB as some contributors on this site my be, my son has a BMW and I still love him. Seriously speaking, when I get into my brand new GLE it makes me feel real good, I hope everyone enjoys his car as much as I do.

It sounds like your source is more reliable than some of the tales we see on this forum.
I think this is our 5th M-B also. Our fourth was a disaster and we came back - hope your problem is transient.

just went trough a similar situation with my 2022 GLE 53 , difference was they fixed it in 1 day . They said it was a cracked EVAP line to the charcoal canister . Defective from the factory .

Man... reading these threads I don't know if I should be excited about the car coming. This will be our first MB and wife is always worried she would not be able to go pick up our son.

Some people vent, some are always bad-mouthing a brand, while others are looking for answers.
Unfortunately for those looking for answers, people in the first two categories seem to dominate far too many discussions.
Fortunately, their numbers are few, although their posts can be many.
These days it seems like a newbies task is to identify those first two categories, and give them less credibility.
Such is the life on the web.

Here's a real tale of woe. My brand new AMG GTR which I was lucky to get and waited a year for broke down in Vegas and was stuck blocking traffic in the valet at the Aria for over four hours. Little long but an interesting read for any who care to check it out.

You won't find anyone on a forum complaining that their car has never had a problem and they are missing out on the stale donuts at the service department. As useful as enthusiast forums like this are, they generally reflect a disproportionate representation of the amount of issues that are occurring. My problems out of the gate were apparently part of an unfortunate batch of defective charcoal canisters Mercedes received early on as I've seen a few others report the exact same issue. The same thing applies to a run of defective 48 volt batteries in the 450's with the with the notable difference that at least a defective charcoal canister didn't require a flatbed. There are a few haters lurking who only post when they see an opportunity to denigrate what is by most reasonable standards, a car that's for the most part no more problematic than any other mass produced product of high complexity during a global pandemic and supply chain collapse. It sucks when something goes wrong but MB will get it fixed and life goes on.

On the other hand, we’ve bough two GLEs last summer and have had zero issues with either one in almost a year of use.
Unfortunately, in forums, a lot of the folks that post are the ones having issues.

Pick your brand, go visit their forums, and you'll see a litany of complaints. The last couple of years hasn't been good for availability, or patience.
