At least in Canada, MB is extending the warranty on M260, but not in US so far:
https://mbworld.org/forums/glb-class...nder-head.html
I saw it earlier but didn't look farther because it didn't apply to either a GLE or my 19 GLC.
I thought it was unusual because it only applied to transverse engines, and also because TSBs usually include VIN ranges.
I also wondered why tha M264 engines weren't included. There must be a difference.
And why only Canadian cars? Consumer protection laws? Different heads?
The TSBReseach link didn't pull up a GLE, either, but I could be using it wrong.
https://en.wikipedia.org/wiki/Merced...60/M264_engine
Warranty extension letter is in accordance with the requirements of the Canadian Environmental Protection Act of 1999, so that is why... It is a very common problem with M260 engines based on my conversation with MB service manager. It is covered under warranty. Problem is if that happens after your warranty expires. That is why Canadians get the extension of warranty. I will call US MB to check on it. Per service manager, they cannot fix it until it happens, so MB should extend the warranty in other countries including US if they are behind their products...
See below link. It is not a recall, it is a service bulletin, which lists the engines. Sometimes it doesn't open for me, so I posted the other link which doesn't have all the cars related to the engines.

It only applies IF you have a CEL and mixture codes. Then they perform a leak down test to verify eroded valve seat.
Just reinforcement that its probably a good idea to consider an extended Service Contract for any modern car.
Do you have any data on the percentage of cars affected?

Here’s hoping the M177 rear main seal failure problem doesn’t become widespread and MB issues a field fix for failed vapor separators. Fortunately the vapor separator itself isn’t terribly expensive, but dealer labor to replace is exorbitant because intercoolers need to be moved or removed in some installations. DIY it shouldn’t be too bad, just time, aggravation and inconvenience on a vehicle, the price point of which should grant the owner immunity to such annoyances.
Thankfully for owners, the 3.0 M256 inline six doesn’t seem to be plagued (yet) with substandard engineering as the fours and eights have suffered.

That said, numbers without context are meaningless. Mercedes had/has supply chain issues, impacting the sales of GLE in 2022. Anybody looking for one, especially 450's will know that.
Wether one likes it or not, Mercedes has been selling every GLE they could get their hands on and demand outstripped supply. This is the very definition of a well selling car.
Personally, I actually prefer the X5 over the GLE but the utility and space of the GLE is simply better (as with the prior GLE model) and since that was the primary purpose of getting the car it was an easy choice.
I agree, GCBC has good data for US and Canada. I pulled the 2022 numbers into a sortable Spread Sheet. Attached is a shot comparing BMW and Merc. BMW surely crushed MB in sales, but then again, they are discounting their cars more than most, and MB isn't (to the contrary actually). Assuming these numbers are right, 82k to 58K for X5 vs GLE is not an ignorable stat.
BTW, the sums in the bottom row are for all cars - I should not have included it as it is confusing.

Clearly, actual reliability isn't on people's minds when purchasing. Or resale, or costs to own and refuel. https://www.hotcars.com/brutal-truth...-owning-tesla/
I don't know who ended up last year with the most recalls after Ford, but it may be Tesla, Toyota and Hyundai again. The "most reliable" according to Power and CR.
If I were trying to predict future market trends as a manufacturer, I think I'd Punt.
The Best of Mercedes & AMG

But again, since one can’t sell what is not available and BMW has had more inventory and less part shortages during the last 2 years.
Was depressing walking into these empty MB dealer showrooms and the sales guys trying to sell future allocations…

I hear you about the inventory, it definitely messes with the numbers and the prices. I believe that things have changed or are in the process of changing though. Can't say about everywhere but my local dealer (in a group of 3 MB dealers in the Boston area) is showing over 50 GLE's in stock (24 of them are GLE53's, 3 63's but only 4 450s) most of which have pictures so I am guessing they are not "in transit". Having said this, they are notorious for high prices and "market adjustments". When I was looking to buy my e450 I saw a G-Class Wagon in their showroom with a "market adjustment" tag at greater than $100k.
I guess my main point here is that sales numbers are governed by multiple factors and I am guessing reliability reports are less of a factor than people think.
The same dealer network has 2 BMW dealers that has just under 50 X5s (20 or so in transit), none have 4 cylinder engines, and from my sources X5s can be had for between $4 and $5k off MSRP (lease). I can't speak for anyone else, but, in a pinch, I would surely buy my 2nd choice vehicle at that price gap (especially if the my 1st choice was selling at over MSRP).

Mercedes sold 63,050 GLE in 2022 for a loss of 3.1% YoY.

I addressed both.
Reliability doesn't seem to sell cars.
The most recalled cars top both "most reliable" lists. Except Ford, who is the top seller, among the least reliable, and most recalls.
Go figure.








I should have said reliability ratings.
People are concerned about reliability, but clearly the Clickbait-ers aren't useful for high end car buyers. The more sophisticated buyers expect more from their cars.
Drivetrains are only 1/9th of the score and infotainment dominated the scores.
If recent reports about a simplified MBUX2 interface is true, it's an example of a manufacturer adjusting to complaints. I expect others do, as well.
Other reporting sources have been mentioned, and those are usually more reliable than the reliability ratings we see on slow news days.
(I'm not talking about the JD Power data as Clickbait - just the media that present their "take" on the actual info. CR is definitely Clickbait, since their car reviews counter their headlines.)
My complaint with the Clickbait stuff is that nobody can explain why the most recalled cars rate high on the polls. There seems to be a disconnect. Maybe its the polls themselves.

^ I definitely agree with this. I'm not going to bother looking at how other brands like Ford, Toyota, etc rank on these lists because I don't care about those brands. But, it is worrying that MB shows up at the bottom of various lists while BMW keeps showing up on top. It's probably a tiny tiny factor at most in my decision making, but I do notice it and wonder.
Thanks for the catch. Why is this data different from three different sources? Is the number being manipulated? Regardless, taking yours, as highest number, 63,050, that is a whooping 30,000 less than X5 or almost 50%. Is that considered well compared to its direct competitor?
How do you know BMW does not have that issue? They do/did. They dropped many features too. Their lots/showrooms were empty too. I remember when I was getting this one, there were around five on this dealer's lot. I had to switch dealership and order because this dealership flipped and dropped some items they had verbally agreed on.
If this is the definition of a well selling car, GLE is not the only. The debate is/was GLE sells as well as its direct competitor. So what is a better argument than the numbers themselves?
That is true and GLE also has other advantages over the X5 but they are irrelevant for the discussion, right?

I just get a chuckle when I see so many media rags parroting the headlines, instead of the meat. Which is behind a Paywall, otherwise the misleading headlines wouldn't get eyeballs.
The responsible media don't even bother. They're the ones to read. And recall history, IMO.

One sentence:
I don't blame Power, just the media who does a crappy job of relaying facts, because we don't subscribe to Power.
Another:
CR is the worst because their subscription articles rate the GLE at the top, but their headline writer also does a crappy job of relaying their own findings.
Not sure why you're arguing though, cuz you're affirming my posts. Oops four paragraphs.

You just have to read a dozen articles to piece it together.
I spent several days before I entered this thread (post 45) deep diving after the release on Feb 9, because of all the hand-wringing and misinformation. Wanted to get my info correct.
My quotes, above, are from some of that research. They are sifted from the Greater BS.
Since I can find real information on their site, they do have it.
Since their headlines disagree with their articles, it's Clickbait. That's giving them the benefit of the doubt.

You're actually agreeing with my posts.
However the other reports I posted from various media, have a lot more information than was included in the JDP PR. They did include a lot more info, which were refuted by their headlines.
I don't think you can defend them either.
