Fuel smell in the engine compartment and visible leaking fuel on the lower hoses per NHTSA Campaign Number 18V837000. I previously complained about this in April 2025 (ID 11669847). Dealer inspected in April 2025 and replaced the lower hose, but I still would smell fuel. After a lot of my own troubleshooting over the last six months, I have determined that when the car has sat un-used for over 24 hours, the rubber fuel lines shrink just enough that the next time the fuel system is primed (pre-start routine when you unlock the car, or start the car), a small amount of fuel leaks out at the connection. If the car sits for weeks and then you start it up, fuel will visibly leak out of the rubber connection (I have video). Once the rubber line swells up again due to the fuel in the line, it will slow the leak. So, if you use the car daily, you will be less likely to notice a leak. If you use the car infrequently, you will be more likely to have a leak.
NHTSA complaint #11708574 — an unverified report by a vehicle owner.
My 2022 Mercedes-Benz Metris recently experienced a sudden onset of engine issues, triggering the Check Engine Light. Diagnostic data retrieved from the vehicle (via onboard telematics) revealed the following error codes via onboard OBD GPS Bouncie: P0300: Random/Multiple Cylinder Misfire Detected P0301: Cylinder 1 Misfire Detected P0304: Cylinder 4 Misfire Detected Upon professional inspection, a mechanic diagnosed the root cause of these misfires as critically low fuel pressure resulting from a failed low-pressure fuel pump. The mechanic advised that the fuel pump requires immediate replacement. These symptoms (low fuel pressure causing engine misfire and potential stall) align exactly with the safety defect described in NHTSA Recall Campaign #23V881 (and the related #23V444). That recall describes a defect where the fuel pump impeller deforms and meets resistance, causing a drop in fuel delivery and potential loss of motive power. Despite my vehicle being the same model year (2022) and suffering the identical component failure described in the recall documents, my VIN [XXX] ) is currently excluded from the eligibility list. Corrective Action Sought: I request that the NHTSA investigate this failure as evidence that the scope of Recall #23V881 is insufficient. The defective fuel pump components appear to be present in my vehicle's production batch. I request the manufacturer be compelled to expand the recall to cover my VIN for repair and reimbursement.

It has been two years after posting an issue with engine light on indicating the error code p052e which is a known problem on many models mercedes has. This metris van is not a passenger van but a commercial van. It has however the SAME engine and SAME error code as all the models mercedes having this engine. It is stated that it is under warranty by mercedes up to 150k, with the exception of the commercial van. This is ludicrous and a failure to correct a known defect and expecting the customer to pay the bill. It is also disturbing that the NHTSA does not communicate to the complaint or direct mercedes to FIX the problem. What happened to Quality and Customer care?
NHTSA complaint #11695391 — an unverified report by a vehicle owner.
Recently took my vehicle in to get the brakes check and inspected. Technician at Mercedes Benz noticed a fuel leak in the upper fuel line. We both thought was very odd because the vehicle only has 35k miles on it and the line is visibly in great condition. I did a little research and found that there was a recall for this exact issue. But it seems that my vin wasn’t in the recall. I contacted Mercedes and told me to reach out to you guys. I’ve had multiple issues with Mercedes upon the delivery of my van. It was missing a Hermes module and had parts incorrectly installed. I ordered this van brand new and picked all the options. I have no doubt that my van some how missed this recall due to Mercedes absolute incompetence as I have had to deal with their incompetence to the full extent to the point where corporate actually awarded me a $1000 check to compensate for my bad experience And now they are trying to charge me over $1000 for this fix when it is clearly a recall.. please help. I had actually noticed the gasoline smell in the cockpit and when I exit the vehicle for over a year. When I asked the Mercedes technician about this they told me it was from installing the new fuel pump that had been recalled and that it would go away. (NHTSA Recall #22V134) due to insecure upper and lower fuel hose connections that could cause a fuel leak and a fire hazard. Best Tim
NHTSA complaint #11686351 — an unverified report by a vehicle owner.
There was a fuel smell emanating from the engine compartment during the vehicle pre-start routine (fuel pump priming). The dealership determined this to be a leak in the lower fuel hose to fuel line of the service connection per NHTSA Campaign Number 18V837000, however they refused to cover the cost of the repair because the recall work was previously completed in 2019. Corporate Mercedes Benz USA also refused to extend any goodwill toward this repair despite acknowledging it is the recall issue because the work was done once and is now considered out of warranty. Recall 18V-837 only requires authorized dealer to inspect and replace as necessary, so I don't know if the previously completed recall work on my van actually resulted in replaced parts or not (I bought this van used after the recall work order was completed). This is a health and safety hazard and Mercedes should have a permanent fix, not give us a part that needs regular expensive maintenance.
NHTSA complaint #11669847 — an unverified report by a vehicle owner.
The pressure relief valve part on our Mercedes van is causing a check engine light to go off with code P052E. It's a known issue on several MB models (GLB, C300, etc.) that this original part wears out and can potentially cause an under-hood fire if oil gets clogged up in the components. To my knowledge there is no routine maintenance that we missed that would be causing this issue. MB has since released a new style of PCV part with insulation wrapped around the hose to prevent condensation build up. It's not possible to get the original stye of that part that is installed on our van anymore because Mercedes knows the part is poorly constructed and will fail. It's a costly and laborious repair (5-7 hrs), yet it seems like they already know it's a widespread and serious safety issue, however there is no recall on it on the 2019 Mercedes Metris as of now.

The fuel line is leaking again. I have had this replaced three times already. Once under warranty and twice out-of-pocket. Why wasn't the MY2016 included in the recall? The raw fuel smell permeates the cabin and is nauseating. This is a safety issue were something needs to be done for a permanent fix before someone dies in a fiery death.

The Crankcase ventilation valve called (Crankcase Rebreather)comes with a defect making engine light to come on after about an average of 50.000 miles, with a code p052e, preventing passing state vehicle inspection. Feedback from many Metris ownership highlights exact same challenge with engine light turned on at all times. But dealership is charging up to 3.000 dollars to remove their own faulty designed part.

The digital display system that indicates how many miles you have left until empty is not accurate. The dashboard display indicated that I had about 85 miles of range left before my tank was empty. Approximately 35 miles later, when there should have been 50 miles of range left according to the digital dashboard display, the vehicle ran out of gas and I was left stranded on the side of the freeway. This is a safety issue. I have read numerous reports of similar incidents with this vehicle in online forums.

New heavy fuel odor in cab. I wonder how much fuel I am leaking. Where is the fuel that is being leaked out go? On a hot exaust system? Fuel line was replaced once by MB dealer. I think they used the same defective fuel line to replace the first one. One of the last times the van was in at the dealer they "didn't have time" to check the fuel line complaint. And there is no mention of my request in the service writers document that says I wanted it checked out.
