Fuel Pump Recall
From Autoblog:
Mercedes-Benz is recalling 143,551 new cars and SUVs to address a fuel pump issue. The impeller — which does the hard work of moving fuel out of your tank and into your engine — may degrade or fail, resulting in poor or non-existent fuel delivery and potentially forcing the vehicle to shut down. Mercedes says the problem arose due to poor material quality control of the impellers as delivered by one of the company's sub-suppliers. This is not only a pretty large campaign by sheer volume but a rather broad one. If you own a rear-wheel-drive Mercedes-Benz manufactured for the 2021-2023 model years, congrats! You're invited to the party.
This recall covers the 2021-2023 GLE/GLS (W167 platform), C-Class (W205, W206 platform), E-Class (W213 platform), S-Class (W223 platform), SL (W232 platform), E-Class Coupe/Convertible (W238 platform), GLC (W253 platform), CLS (W257 platform), AMG GT 4-doors Coupe (W290 platform) and G-Class (W463 platform), including the AMG variants thereof. In total, Mercedes counts 76 individual sub-models.
"Due to a deviation in the production process of a sub-supplier, certain fuel pump impellers might not meet the material requirements and thus certain batches of fuel delivery modules might not meet the durability requirements," the company said. "As a consequence, the impeller might deform and therefore come into contact with the fuel pump housing, leading to a mechanical resistance. In some instances, this could lead to a shutdown of the fuel pump. As a result, the vehicle could lose propulsion, which could increase the risk of crash or injury."
Mercedes says performance degradation may occur before the pump fails outright, and a malfunction message will display in the instrument cluster if adequate fuel is not being delivered to the engine. Once the deterioration reaches that point, engine performance will likely be tangibly impacted. Mercedes will begin notifying dealerships of the recall campaign immediately; customers should expect notices to arrive in August.

It should be vehicle specific since they should know exactly which cars had that run of pumps installed.
They even know what tool tightened every screw.

and the NHTSA one:

Is that true that the GLE 350 is not included? Am I reading that right?

FYI for anyone trying to get this fuel pump swap done sooner vs later: My SA said today that the earliest they can order a new pump for the recall to be covered is 8/15/23, so they set an appt for me. I know the notice says Customer letters will be mailed on or before August 25, 2023. I want to get mine swapped out asap. If it fails between now and 8/15 it should just be a warranty item anyways....

Do you think that they will have them in stock, or only only order when a car comes in for service?
There's what, 143,000 cars affected? Did they expect a shortage or delay?
I guess I'll keep the tank topped off, to keep it from working harder. It might help. Probably not. About 30k miles now.

I called and my dealer said the part hasn’t been released yet and they have no ETA.
I wonder who pays for all of this. 123,000 vehicles at says $2,000 in total MB warranty parts and labor hours to repair (just a wild guess), that’s roughly $250 million, or a quarter of a billion U.S. dollars. I don’t know how the supplier contracts are setup, but I can only imagine if there is a verified defect, the supplier will ultimately get billed or sued for all of this, assuming it doesn’t bankrupt whomever that supplier is. Unless of course, Mercedes inspected and approved of the pumps on a very firsthand basis, which I hope they did. In that case, that might relieve some liability.

Is anyone able to check 2 vins for me to see if they are impacted? I am unable to get through to anyone at Mercedes to confirm.

So I spoke with the parts manager, until the recall campaign for the fuel pump delivery module is actually released we cannot pre-order any parts, nor will we know anything about parts availability until it is actually an open campaign.
My guess is that they'll have the car a couple days to get this done. My hope Is that with the sheer number of affected vehicles they will stage the replacement parts in the regional distribution warehouses for quick delivery when the recall is opened up. At least that's my glass half full outlook.

From reading another article mentioned on another thread from another forum member for a different vehicle but covered by this recall, MB first was aware this issue over a year ago, supplier changed production method/spec without notifying with MB, hopefully that means MB has prepared ample supply of pumps for this recall.

I'm from Canada and there is no recall yet here. I called the dealer and he said just because there's a recall in the USA doesn't mean it's going to be in Canada also.
He said they have not been notified of any fuel pump issues.
Weird, they all come out of the same plant at different times though.
We'll wait and see I guess.

I got this recall notice. But when I try to schedule the appointment with dealer, this recall is not listed. What should be the next course of action? Should we wait until mercedez send confirmation to schedule the appointment or can we go ahead and replace it and pay with our own money.?

Was your notice specific to your car, or just a general notice?
Did the notice give you specific directions? And the dealer didn't honor it?
If you have had symptoms, it should be covered under warranty, recall or not.

It's specific only to certain VINs. You may be able to ignore it.

It is specific to my VIN and my when login with my VIN, it shows the notice there too. This is the 3rd recall notice for my 2022 GLS 450. Looks like very bad manufacturing process just to meet the customer demand. Instructions on the letter say remedy not yet available and when the delivery module becomes available they will send the notice to schedule appointment with the dealer.
From article:
"The German automaker started investigating said condition back in June 2022, following a rising number of reports from outside the United States of America. Retrieved pumps were analyzed together with the supplier, Hyundam Industrial Co. from South Korea."
"Merc also discovered that Hyundam implemented a few changes to its production processes without informing the automaker. Changes included the switch to a different supplier for the raw material, a new injection molding process at the injection molding supplier, and more quality controls across the board."

Is the pump in the fuel tank? I hope not. Don't relish the thought of having the fuel tank dropped to do this or taking out some of the interior to get to an access point from the top to replace it.
