Sadly after about three weeks the problem occurred again for me as well. The conditions that you are describing are almost exactly the same for me. Damp out and slight downhill seems to trigger this issue. Depressing the brakes for about 20 to 40 % in hybrid mode and it bounces off to activate the combustion engine for some weird reason and then the warning message comes on (but no check engine light yet), if I give it gas the check engine light comes and I lose throttle response. Currently have another service appointment scheduled for this Wednesday.

Let us know if the dealer recommends that you move to Tucson where it's flat and dry (lol).
Following thread with interest. I have been reporting about these issues with my '23 EQB. It is currently in the shop again and I have initiated a buy back through a lemon law attorney. Too early to determine MB's response. In shop for third time for sensors that disabled. The third time was accompanied by the "turtle mode" as I now call it. After 2 weeks in the shop, MB engineers determined it needed a new rear motor. The dealer has not answered my question about whether part comes from Germany or US, but I am presuming Germany. I do not believe any of these EV's or PHEV's can actually be repaired once these issues start and essentially MB is making an interior EV product. And my loaner car is ICE vehicle since dealership says they have no EV loaners. All I want right now is a buy back and to get this vehicle out of my life. Going to try my luck with a BMW iX as soon as I get a settlement from MB.
But I liked Ipana toothpaste with Buc-e Buc-e Beaver (dating myself). Agreed that it is one ugly car.
BMW solved the coolant leak issue. And I guess no vehicle is trouble-free. But leased the EQB in July '23 and since Nov '23 it has been a constant source of trouble. The dealer is clueless about what to do and gets its cues from MB engineers. The MB engineers are clueless and nothing they suggest works. And now I face at least 3 months of the lawyer fighting with MB. I have a phenomenal dealer with attentive sales and service. They really are not allowed to get involved with advocating for me with MB (lawyer or not).
Had pondered a GLE450e but seems to be prone to the same issues as the EQB. I can only conclude that MB PHEV and BEV cars are flawed.
Prior to this had '21 GLE350 and before that GLC300. Both cars were flawless and the only issue was squeaky rear breaks after getting the GLC.
After 3 trips to dealer on a 2024 GLE450e w. 1800 miles on it and 90+ days out of service, 10 day lemon buy back letter and 2 months with buyback request open, I was contacted today that they are going to buy it back.
Dealer has it for 2-3 months this visit and they have no idea what is wrong with it. They are just saying factory engineers gave them a list of parts, wires, sensors, pumps etc to replace since all of the last replacements didn't fix anything. Said the parts are still on backorder with no ETA however they keep building new ones with the "parts" we supposedly need but are not available.
This will put an end to this story and hopefully they negotiate fairly. They can see that I have (4) Mercedes in my house currently and I am glad I kept the 2021 GLE 53 which has never had issues. I will be going back to that one or my ML63 while we wait to see what is next. I think it may be time to consider another brand after this terrible experience.
so glad for your success. i am hoping for similar success with my eqb300 although dealer now claims it is fixed. I do not believe it for a moment.

I am having the same problem. Problem started with ~1600 miles on the vehicle in early July. I live in Maine and it has been really humid lately. The problem happens consistently when I am going up hill. It's at the dealer for the second time and I'm sure the are clueless as to the cause.
I am disheartened to hear of all of the problems. I really like this car and wanted it to work out. Now I'm beginning to prepare for a buy-back battle. I bought the car in Virginia but live in Maine. I suppose the Virginia lemon laws would apply. In any case, I would love to know if anyone has successfully had this problem fixed. Thanks!

I've written about my EQB sensor issues and my failed lemon law case. Live in NJ, bought car in NY so NY Lemon Law applicable. Lemon Law atty was unable to get MB to budge and he did not believe filing suit would result in favorable verdict.
Since you bought in VA, the VA lemon law will be applicable.
BTW, my EQB required a rear motor replacement which they said was the cause of the "reduced power" issue.
Thanks everyone for the help. I picked my car up from the dealer two days ago. After 200 miles,so far so good. Here is what the service record said:
2315 installed battery maintainer, sds,short test. Found code (P0A9300 The cooling system for the low temperature circuit has a malfunction.) stored in power electronic power unit. Processed fault code and it states possible air in the coolant system. Removed all upper and lower engine panels, completely drained the low temp coolant system.Reinstalled all panels.Used a vacuum bleeder to fill the low temp coolant system as designed. Performed the automatic bleeding procedure using the sds in the ptcu control unit three times. Performed an extensive overnight road test and no warnings or codes returned.
So, here's hoping that the problem is fixed.
All I can say is that I never had problems like this with my Hondas.
How I wish I had visited this site and read about all the postings on the GLE 450e before I bought my 2025 GLE450e !
Took delivery of my fully loaded 2025 GLE450er on August 31, 2024 from the MB dealer in Chicago area. The car is beautiful and I loved it ! The range of the EV battery is perfect for my daily commuting to work, I was very happy with the car.
Then, on October 6, 2024, the 5-week old car with only 850 miles (~90% electric) displayed the Check Engine Light that would not go away. The car has been with the dealer for service for ~10 days now. The diagnosis given to me is a faulty (leaking) EVAP hose which they have to order from Germany. I can only hope that my problem is this simple and the part will arrive soon to solve the problem. Somehow, I have a deep suspicion that is going to be the case.

Cars are highly complex made up of thousands of parts from different suppliers. I wouldn't be worried about a failed part. The real worry is when the dealer says they found no problems or a software update is expected in the future to fix your problem.

Thanks again for the support.
So… car has been at the dealer since September 6. They have no clue what is wrong and started replacing everything they could think of. I hired a lawyer and am exercising Virginia’s lemon law to get a buy back.
MB has permanently lost another customer. Will replace it with a BMW x5 xDrive50e.

Sorry for your troubles. As annoying as your predicament is, just be aware that BMW isn't any better. Just read around bimmerpost before you jump ship so you can make an informed decision. Plenty of lemon, recall/stop orders, CEL threads.
Yea I'm switching to only Japanese cars, specifically Toyota and Honda ---- no where near as fun to drive as their German counterparts but at least you're not pulling your hair couple times a month

Now that those brands have updated their technology (last year or two -finally), their complaints and recalls have shot up. Also true of BMW and Audi, who are updating seven-year-old models.
Those are not really reliability studies. They are Initial Satisfaction Surveys - "was the car what you expected" is the general nature of the questions. Cheap car: low expectations. Expensive car: high expectations.
Powers also rated Hyundai top of the heap when their cars were leading even Ford in recalls, for serious things like engine failures, not confusion over menus.
If you want a reliable car, don't buy an advanced automobile, especially one that Powers or CR rates highly. Get one at the end of their model cycle. And RTFM.

If I could keep only one of my current vehicles, it would be my '95 Jeep YJ. There's nothing in between the two bumpers that I can't repair. Come to think of it, I've replaced both bumpers too!

Thanks, Wildta. I will definitely research the new car before buying. I may go back to Honda or Toyota. FWIW, Consumer Reports rates BMW as the best auto maker in it's latest report. MB ranks 29. https://www.consumerreports.org/cars...s-a6159221985/

A tribute to Aged Out models, nothing more. Get a 6 or 7 year old car and most of the bugs are gone.
It also shows that Slow tech and No tech is more reliable than new tech. With menus that people struggle with.
And those aren't reliability reports. They're popularity reports.
Cupholders are the CR reviewers' most important, critical features. They hate MB's cupholders with a passion.
Second priority? Too many dark interiors. Watch their online processes and discussions. It's a Parody of real reviews.
