Mercedes-Benz Metris 2019 — Reported problems

My 2019 Mercedes-Benz Metris, with approximately 78,000 miles, developed a check-engine light and diagnostic code P052E/P052E71 for a failure involving the positive crankcase ventilation/crankcase ventilation regulator system. I was advised that the repair will cost approximately 3,000 because the failed ventilation component is part of a larger assembly. I am concerned because Mercedes-Benz has acknowledged this same P052E71 crankcase ventilation failure on other Mercedes-Benz models equipped with the M274 engine and has provided extended warranty coverage on certain vehicles. My Metris also uses the M274 engine, but Mercedes-Benz has excluded the Metris from that extended coverage. I have also learned that other Metris owners have reported the same P052E/P052E71 failure. I am filing this complaint because I believe this may be a recurring defect in the crankcase ventilation system on M274-equipped Mercedes-Benz Metris vehicles and should be investigated to determine whether these vans should have received the same repair coverage or corrective action as other affected Mercedes-Benz vehicles.

A check engine light on a Mercedes-Benz Metris, accompanied by a P052E code, often indicates a problem with the Positive Crankcase Ventilation (PCV) system, specifically the PCV regulator valve or its associated components. This code signals that the Powertrain Control Module (PCM) has detected an issue with the crankcase pressure, suggesting a malfunction in the PCV system's ability to regulate pressure.

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 contact owns a 2019 Mercedes Benz Metris equipped with Hankook Tires, Tire Line: Ventus S1 Noble, Tire Size: 225/55/R17, DOT Number: (N/A). The contact stated that while driving approximately 70 MPH, the rear driver's side tire experienced a blowout. The cause of the failure was not yet determined. The vehicle was taken to the local dealer who replaced the tire. The contact stated that all the original tires on the vehicle were replaced due to premature treadwear. The manufacturer was not made aware of the failure. The failure mileage was 23,000.

There is an active recall that Mercedez is ignoring.

This recall was issued on July 7, 2022, nearly 6 months ago. The recall involves a sticker. This vehicle is rented out on Turo. Turo delisted this vehicle due to this open recall costing us over $1,000 in lost rental income for our business. Payments on this van are nearly $800/month. This is causing enormous financial pressure on our business with no end in sight. We do not believe it should take 6+ months to replace a sticker. Additionally, the VIN plate on this van is nothing more than a sticker on the dashboard. The VIN plate was damaged when the windshield was replaced last July. Now we cannot even sell this van. It is taking forever for MB to provide a new VIN plate to the glass replacement company.

THIS VEHICLE IS EQUIPPED WITH ELECTRONICS STABILITY CONTROL (ESC) WHICH INCLUDES CROSSWIND ASSIST. THE CROSSWIND ASSIST IS THE SOURCE OF THE SAFETY PROBLEM. The crosswind assist will engage in strong crosswinds and in certain road conditions such as a dip in the road or an off camber dip it immediately brake one side or the other causing the vehicle to quickly and unexpectedly lurch to one side or the other. I've experienced this multiple times and it has the potential for causing serious accidents. I communicated this complaint to my Mercedes service tech. It is a known problem on both Metris and Sprinter vans. It cannot be disabled from ESC. I was shocked to find out this has been reported to Mercedes multiple times and there has been no corrective action. If this defect has not killed anyone yet (that we know of) it certainly will. Even though there are not that many Merceds vans on the road in the US this problem is very serious and needs to be addressed quickly. Please update me on this problem as soon as possible. I am very uncomfortable driving this vehicle in its current condition.
