The check engine light came on and the code reads PO52e. Mercedes has a Intake Line Assembly Extended Emissions Warranty (Code P052E) up to 150,000 miles. Theyâve admitted this was a problem with this engine but only covers 3 other vehicles with the identical platform, & excluded the Mercedes Metris

The contact owns a 2016 Mercedes-Benz Metris. The contact received a notification of NHTSA Campaign Number: 22V482000 (Tires); however, the part to do the recall repair was not yet available. The local dealer was contacted; however, the recall repairs were denied, and the contact was asked to take the vehicle back to the original dealer who sold the vehicle. The contact reached out to several other local dealers; however, the assistance was provided due to the vehicle having approximately 18inch rims. The manufacturer was made aware of the issue, but no assistance was provided. The contact had not experienced a failure.

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…

How does the digital display suddenly disappear from your dashboard? Mercedes has lost its respect for being a High Quality brand. Too many recalls,. Too many issues that vehicles less costly never have such as 1. Out of alignment at 0 mileage resulting in worn out tires at 12k miles. Realignment that was useless at mb specs resulting in third set of tires. 2. Pcv regulator valve triggers engine code p052e which means a $3000 repair bill that's not covered on commercial vans but covered on passenger vans with the same engine. 3. Digital display on dashboard gone. Yet cars in the 60's with digital screens still working. Thanks Mercedes for the Quality and commitment you have to your…

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?

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…

2016 Metris Engine M274 Check engine light, P052E71 Crankcase ventilation valve- Oil leakage- safety is compromised as this damage causes engine failure. The dealer has confirmed multiple oil leaks and other parts and service is required at extensive cost to me. This is the same damage and failure that passenger models with the M274 engine have an extended warranty available to them- my PASSENGER Metris with the exact same engine is excluded from this extended warranty.
