GLE 400d suddenly losing power

[Georgie1201]

We've got a 4 month old GLE 400d which has 4,500 miles on it and has started to lose power on occasion. There's no response from acceleration, the dashboard remains illuminated, but the mood lighting goes off. I have to pull over, stop the car and restart the engine.

Interestingly, before we bought this beautiful car, we had a credit hire GLE 400d whilst our old Audi Q7 was in for repair. It did exactly the same thing which I put down to a one off, but did report it to the hire company.

I'll be booking it in with Mercedes to have it checked but wondered if anyone has experienced the same issue with this engine and if so what was the outcome?

Thanks

Good morning to you. With a 4 month old car you're doing the right thing in taking it to MB. Let them sort out the issue.

Welcome!

As the 400d engine is fairly new there has very little feedback on problems other than tandem oil/vacuum pump failures which is situated in the sump.

Do report back when MB have made a diagnosis and rectified the fault it’s good reference for the forum

This, there is around 200 pages thread on the German forum on the w213 400d, apparently it’s a engine out job, if it is the above problem, at least yours is still under warranty.

Would you mind pointing me to the German forum that has this thread. Thanks

I thought i had better write up my current situation with my 2020 E400d. (December 2019 build date) Bought the car in June, 1 year old. Apart from the boot lid opening itself once in a while and a very occasional issue with the gear stalk not selecting properly (and the 20" wheels getting...

Yet another particularly stupid design being in the f sump. Heard vw did same thing someone PLEASE explain how that design is any use to car owner over origional safe, easy access, decades old, simple, design.
I can't wait......

Like you I don’t understand the logic of the ‘engine designers’ a tandem oil and vacuum pump situated in the sump repair and replacement is likely to write the vehicle off at 5+yrs old (dependent on mileage) and certainly at 10yrs old these vehicles are being built to fail unfortunately. I look at buying the S213 E43/53 estates with a dilemma do I really want to buy a complex engine made by MB I’m losing brand confidence which was not the case with the S124, S210 and S212

Look and be prepared to pay for mint older model wud be where I going. Otherwise ur going to have to pay out for things designed to stop u from fixing, or get another job so u can pay for others to do wot used to be simple "we are being driven down this road" no question in my view. And even if u do yrself ur driven every Yr into a new dead end ref tooling as the b, s. Change a perfectly good fixing just so you need to buy a new "tool".
Older, I have the tools, older, I can fix it, older, prob more reliable, older prob more pts around, older parts prob cheaper, no £1000 pound headlights, older no bolt on dtf, older, might even go up in value, older, might not be dead in 8.1 Yr!!
Admittedly not maybe best plan on motorway commutes but for sure has many + sides unless u deside u must have a "special?" place to sit.o call it iPhone desease, every Yr people que round the block for a 1000 pound phone to me that's just nuts
But they fall for it. I have just reached the point of 200 euro phone. I use phone to make, receive calls emails n a little surfing, I am still quite capable of turning my lights and heating on myself. Same with car functions. As far as aware speed limits near same, or less than 25vyr ago, so I don't need a, 1000 pound headlight that can illuminate the moon a lucas unit converted to h4 that I can get at without taking a day off work would do me fine.

Back from Gatwick Mercedes yesterday. No fault codes found. They checked the pressure of the tandem oil & vacuum pump and all ok there. Battery all ok too. However, it does need some software updates, which can take up to 4 hours to complete, so will be back with them next Thursday.

Great let’s see how you get with the updates, I do hope that fixes it for you as no doubt it’s annoying to live with.

With reference to ajlsl600 and Malcom, it’s very simple. Consumers are blindly wrapped in the ‘keep them poor net’. With cars being stolen, lasting 5 minutes causing terrible financial impact when they shouldn’t, people will just go and buy another. People want badge as they falsely think material things show a sign of wealth/status. When in fact different things actually suit different people. Even better for the industry if they are leased so whack up the price some more to deter people buying anything outright. It’s all win win for the industry. It should just say it all when even in this day and age folks dance around if a car can make it to 100,000 miles without issue.

Yet I have 20+yr old cars that are barely getting run in at around 200,000 miles and several track days, regular speeds in excess of 160mph etc and they don’t bat an eye lid, on original water pumps, wheels bearings, engines just as strong as they ever were, no rust underneath, no annoying warning lights or noises, all rubber hoses still strong as they ever were. On these even I’m capable of performing mechanical and electrical work. Oh they have also gone up in value…..

It’s sad as the ability to make cars genuinely last a long time and be reliable, provide headache free motoring is there but it won’t do the industry’s profits much good.

That's always been the case though. In the US General Motors expected their 1957 Chevrolet model to have a life expectancy of 3 years but realised in the early 70's that the majority of that years production were still on the road. Many of course still are, including mine which, largely unrestored, has just passed it's 65th birthday. It's of no advantage to manufacturers to produce cars that will last years, unfortunately.

Consumerism has gone mad IMO vehicle manufacturers should be designing their products to last longer.
As regards my E43/E53 dilemma I’ve come to the conclusion that the M276 V6 in the E43 is my preferred option due to the fact that the engine core has been in production for some time, it’s easy to service/maintain and most of the inherent problems are known about and I’m quite happy with the addition of twin turbos and an intercooler to achieve the power gains.
The E53 M256 engine seems to have a tendency to overheat from the feedback I’ve read (which might be something to do with the hybrid element), what I’ve looked at for sale has been moved on regularly which is a red flag for me and finally too much unproved new technology ie the combined starter/alternator/electric motor - can you imagine the cost of replacing that

All consumer products should have a minimum 30yr lifespan, with component level spares available for the life of the product. And no modular repair units at £xxxx costs permitted.

Fairly definite that manufactures and governments wouldn’t go for it, however that is what Greta and all her woke chums should be campaigning for.

Maybe the woke generation will wake up and campaign for something that would make a difference.
I worked in the nuclear power industry and everything we produced had a design life of 25 years and aren’t we appreciative of that now with so many nuclear stations having their generating life extended to cope with the absolute mess we are in. The demise of the CEGB/Gas Board was collateral damage from Mrs T taming the unions and Tory greed of course and we are now paying the price unfortunately with no security of energy. I understand why we have burnt huge volumes of gas to produce electricity it gave NG finite control of meeting electrical demand but it was too noble a product to waste in this way - rant over lol
