Oh boy here we go. In the ~14 days since my wife and I bought our 2022 GLE 580 we've driven 1060 miles, mostly from a roadtrip taken last week - been absolute perfection. UNTIL today. Driving into our garage she hit the brake and the engine auto-shut off, restarted, and then violently started shaking - all while her foot was on the brake. CEL came on and once my wife hit the gas again to finish parking the shaking went away. No notifications from the Mercedes app other than my maps are ready for an update.

I am mentally preparing myself for the nightmare @BACnMercedes went through but hope I am overreacting. I mean, Mercedes discontinued most V8's for almost a year to sort out "quality issues". This shouldn't be happening for what the car cost. I maintain this is the best vehicle I've ever owned, including a prior L405 2017 Range Rover Diesel TD6 (no issues).

Have any other GLE 580 owners (abit, I know there aren't many of us) also experienced this issue since BACnMercedes did ~18 months ago? Scarily enough, your old car has been on sale since 12/13/2021.

It sounds like a bad misfire, especially considering it started right when the auto start/stop disengaged. Something didn’t work or failed to activate when it disengaged causing that horrible misfire. It could be software related or something more nefarious like a hardware component that is failing (like ignition coils).

Frankly, I turn off that auto start/stop feature every-single-time I start the car. The pittance in fuel saving isn’t worth the wear and tear.

 

I agree with you. Personally I am already getting 12.4MPG (granted with a heavy foot) - me mostly driving. I loathe the stop/start system for it's complexity when I used to own a 2015 Yukon Denali w/ a 6.2 that averaged 14.5 MPG.

Again, the GLE is obviously superior but at a certain point I don't care about fuel economy and just want a vehicle that has only the complexity needed. AKA a 48V mild-hybrid system that doesn't seem to produce meaningful fuel economy improvements while adding some unknown cost to the MSRP for its existence.

It has a warranty of course so for now it's going back to Park Place so they can diagnose. Will keep everyone updated - 1st appointment is 3 weeks out

 

Yeah I averaged a mere 13 MPG city driving in my X5 M50i and that was literally driving around like a grandpa. Having that V8 and insane HP was certainly nice, but in reality, I rarely ever used all of it other than the occasional stoplight escape. This V6 is enough for me and I’m averaging 18 MPG doing the same grandpa-like city driving.

Good luck. I’m sure they’ll sort it out.

 

Uhh I6.

 

With our '22 GLE450 SUV I6 and 7,922 miles, we are averaging 18.8 MPG in mostly cit driving down here in Jupiter, Fl.

 

 

Thanks! Informative post!

 

I've been a long time lurker on here before purchasing. Not seeking to needlessly bash Mercedes or the V167 platform, just a little frustrated having a potentially large issue so early on.

More-so curious if I was the only one to experience this since someone else reported on it ~18 months ago. But I have a warranty, a great dealer and faith it'll be resolved. I'll be sure to update the thread with what the dealer tells me in 3 weeks or if the issue happens again. Took 2 small trips today and so far nothing

 

I got tagged but there’s not much I can add for help. Good luck.

 

Well, I know it's easy to assume the worse, but I would just wait until you take it in and see what they say; there's no point worrying about something you have no control over. Just drive and enjoy it as it could be something innocuous. If it starts misfiring while idling or driving, well that's another matter and I would drive straight to the dealer, appointment or not.

I'm surprised your dealer is so backed up. I was able to schedule an appointment within two days for a cosmetic issue.

 

Could be bad gasoline. Let us know what dealer says.
Good luck!

 

Dealer couldn't replicate the problem but I had no proof of the check engine light or shaking I felt. Fast forward a month...out of nowhere while driving I got a general "error" message followed by the infamous 48V error. Luckily though the car didn't stop working and was able to restart without the error coming back. Need to get this checked out more thoroughly since I travel to visit my parents in Northwest Arkansas and traveling through middle of nowhere Oklahoma is the last place I'd want this issue to come back. ~2,700 miles

Providing this as a data point for others that maybe the 48V system hasn't had all the wrinkles ironed out yet. Will update with what the dealer says

 

In case anyone comes across this thread in the future I wanted to close the loop out after finally getting my GLE 580 back from service after (3) weeks!

Told me they'd replaced the battery only to 180 and say no replacement on the 48V battery - apparently codes are only stored for a limited time so if you see errors like I did, drive straight to your dealer - their instruction. My SA confirmed they are having a lot of issues still with the 48V battery on the EQ Boost systems (GLE 450 and 580 - likely soon to be 350 too given the new C300 uses EQ boost). Mine is a June 2022 build. The 48V battery is fully covered by the 4yr/50K warranty but NOT by any MB extended warranty. Replacement cost was quoted at $586 + tax which I find reasonable considering the technology and how I thought it'd surely cost thousands. Biggest downside is a fatal 48V error results in your car being inoperable, unlike a normal 12V battery where you can get a jump or plan ahead with a jumper box.

Oh and they also fixed an air vent that wouldn't open from the factory, rattle in the sunroof, creak in the steering at slow speeds, air balance that wouldn't work and a whistle in the driver's side mirror. Got a free full detail which helped but wow! Too many issues to have under 4K miles. Lucky for Mercedes they built one hell of a car otherwise I'd be running for the exits. After picking her up and wafting onto the highway hearing that V8 roar, all was forgiven.

 

Thanks for your report on battery warranties. We were hoping for longer because of the "hybrid" association, but I'm not surprised.
I AM surprised at the low price of a replacement, though.

Hope your car (and you) has paid its dues and the next 80,000 miles will be trouble free.

 

Good god, three weeks is a long time. I wouldn’t be happy and would ask for some compensation. I have as many issues as you under that many miles. I have a creak in the in the steering area as well although I thought it was the MBUX screen. I also have a rattle in the headliner. Did they explain what they did to fix those?

I have another one that just started: my Burmester completely went silent. I had to shut it off and restart it twice before it came back on.

 

Thank you @mikapen ! Happy to help and fingers crossed you are right.

@Frenetic Here are the pages on my invoice from the creaking steering wheel and sunroof rattle issue, hopefully this will help your dealer replicate and fix the issue.

 

Did you custom order that 2022 GLE or was it sitting on the lot? Either way, do you have a build date for it?

Asking cause I was hoping that these issues wouldve been sorted out by now on new cars

 

I got really lucky and happened to find it on the lot right after the dealer got it in July. Was a June 2022 build (99% sure but it's 40F outside right now and not checking the door VIN sticker). Look, I get your frustrations. Personally, I blame the chicken tax - I wish our German vehicles were built in Germany. But this is the globalized world we live in and despite the issues (MB is not the only brand with issues! Remember, the same suppliers make parts for most OEMs) I think it's still a great vehicle. What makes a big difference is how your local dealer is rated and how they handle issues. Ideally these are teething issues and from here on out it's smooth sailing. We shall see

 

Gotcha, thanks for the info.

I have never owned a Mercedes but I ordered a GLE 63S Coupe last month. So I've been doing my research both before and after the order to prepare myself lol.

 

I think you will be so satisfied with your GLE 63 S Coupe! You will get the hand-built and more powerful version of my V8 engine - jealous! Video below is fascinating to watch


Don't get me wrong, you will have issues but they can be fixed. Complexity is a byproduct of what makes vehicles like these so wonderful to drive and special. Unless you are (and I don't think this is the case) planning on owning past 100K miles, you will be happy with your purchase.

 

The Chicken Tax only applies to light trucks, which is why the Sprinter is assembled in South Carolina. The Alabama plant isn't about getting around the Chicken Tax, it's simply about reducing assembly and shipping costs.

 

If that quote is for the 48V battery, I would double check it — it is unbelievably low for a Lithium Ion battery. That quote sounds like it is for the AGM 12 Volt battery — perhaps they made a mistake and looked up the wrong one?

 

A lot of SUVs are classified as light trucks and the chicken tax does apply here. It's likely why the EQS is German made and the EQS SUV is built in Alabama.

I asked her that because I agree, it seemed low. She seemed confident in the quote and said they do these all the time, the 48V battery is apparently not much more than a 12V. Would love someone to either confirm or refute that as my willingness to be on the hook for a very expensive battery past 50K is 0.

 

Best bet would be to call the parts dept and give them your VIN and have them look up the 48V battery. For the record, I do hope the price you were quoted is correct. On Google, assuming I’m searching for the correct battery, I’m seeing $1200-$1600 for a used one. That is still better than I thought, so maybe the quote you were given is correct…however it might be the dealer cost.
