2016 Mercedes-Benz Metris

On November 27, 2018, Daimler Vans USA, LLC submitted a Defect Information Report (DIR) to NHTSA describing two engine compartment fuel hose connection defects in certain model year (MY) 2016 and 2017 Mercedes-Benz Metris vehicles (Recall 18V-837).The recall scope includes approximately 12,383 Metris vehicles manufactured from March 2, 2015 (SOP) to March 15, 2017.The defects may result in leakage from an upper hose connection that feeds the high-pressure fuel pump or from a lower hose connection of the fuel transition hose between the underbody fuel line and the Shrader valve.The upper connection defect was caused by thermal aging of the hose material (Veritas hose), resulting in a loss of elasticity over time.The thermal aging of the hose leads to a progressive reduction of sealing performance, which is most evident at low ambient temperatures.The problem was corrected by changing to a hose with better material properties (ContiTech hose).The lower connection defect was caused by a manufacturing process problem, where the hose clamp may have been installed using an incorrect tool.The recall remedy involves replacing the upper and lower hoses and clamps, as necessary, and ensuring proper installation. The Office of Defects Investigation (ODI) opened Preliminary Evaluation PE18-002 to investigate nine (9) complaints (VOQs) reporting incidents of gasoline odor or leakage in nine (9) model year (MY) 2016 Mercedes-Benz Metris vans (subject vehicles).Eight (8) of the VOQs indicated that the problem occurred in cold ambient temperatures, either during engine warm-up after a cold start or after the vehicle had been parked and shutoff. Two (2) of the consumers have indicated to ODI that the problems were diagnosed by dealer service technicians as the upper hose connection defect.As part of PE18-002, ODI analyzed information related to the incidents reported to the Office by consumers and analyzed the information provided by Daimler Vans in response to ODI's information request letter.The fuel hose leak field experience shown in the Failure Report section of this resume all involve vehicles covered by the Daimler Vans recall.This Preliminary Evaluation is closed with recall 18V-837.VOQs associated with the investigation: 10936026, 10936184, 10991876, 11054491, 11057992, 11063437, 11063829, 11104437, 11138922, 11139024, 11140844, 1150262, 11152201.

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 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.

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 customers.

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?

The contact owns a 2016 Mercedes-Benz Metris. The contact stated that while driving at 40 MPH, the steering wheel seized, and the vehicle became difficult to maneuver. The contact stated that the failure occurred immediately after driving over a speed bump, and the message "Power Steering Assist Malfunction" was displayed. The contact pulled over into a parking lot, and the vehicle was towed to a body shop to be diagnosed. The contact was informed that the power steering wire had overheated, causing a failure. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 17V595000 (Steering); however, the VIN was not included. The manufacturer was not made aware of the failure. The failure mileage was approximately 75,000.

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.

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.

ASSYST PLUS service reminder appears earlier than expected due to vehicle operating conditions Complaint The ASSYST PLUS service reminder appears earlier than expected. The customer or dealer may report that the vehicle did not reach the starting maintenance interval shown in vehicle documentation, option coding, sales literature, or the Owner's Manual. The service reminder may appear significantly earlier than anticipated even though no faults are stored and no malfunction is present in the vehicle. The remaining distance and remaining time continue to decrease normally until the service reminder is displayed. Cause This condition is not caused by a malfunction of ASSYST PLUS. ASSYST PLUS is a dynamic maintenance management system that continuously evaluates vehicle usage and opera-ting conditions to determine maintenance requirements. The starting maintenance interval specified by variant coding represents a maximum interval that may only be achieved under favorable operating conditions. Actual maintenance intervals may be significantly shorter depending on vehicle use. Vehicle operating conditions such as driving conditions, engine load, engine operating conditions, idling, short-trip operation, environmental influences, oil aging, and Diesel Particulate Filter (DPF) regeneration activity may reduce the maintenance interval from its starting value. These conditions may accelerate engine oil aging through increased soot loading, fuel dilution, moisture accumulation, and additional engine operating stress. As a result, the remaining distance and remaining time until the next service may be reduced from the starting maintenance interval. Remedy Do not replace any parts. A due service must be assumed if the maintenance data calculated by ASSYST PLUS indicates that service is required.

Acoustic Warning or message occurring when a closed sliding door is not recognized Complaint Customer may state the warning message or indicator accompanied by acoustic tone alerting the sliding door is ajar when the door is completely closed Cause There are several reasons that lead to the failure occurring: - Mechanical damage through bending when loading and unloading - Worn contact plates --> After detachment of silver plating, the coper plate is corroded - Movement of sliding door/body when driving --> Contact pins do not always make contact with contact plate --> Central locking system fault message in instrument cluster Remedy In a problem case, replace contact switch for vehicles with +T50/+T55/+EL9 or contact plate with A4478201903. Remember to check the fit of the sliding doors and make any necessary adjustments as per AR72.16-S-1023E (447/448) and AR72.16-D-1023TS (907/910). Further valid damage codes: 82326 Contact switch for central locking system on sliding door 82347 Contact plate for central locking system on sliding door 53196 K/Z contact plate for central locking system on sliding door 82645 Contact switch for sliding door

OM642 DPF Filter Cracked or Broken Complaint Vehicle will not start or exhibits noisy exhaust. Check Engine Lamp (CEL) is on. Multiple control unit communication and system faults may be present, including but not limited to: 134800, 134900, 11B300, 11EC00, 15E100, 155700, 162500. Additional events codes may include: 134300, 102200, 163400, 16CE00. In many cases, multiple unrelated faults are stored due to electrical disruption from wiring damage rather than indivi-dual component failure. Cause The DPF filter is cracked, broken, or leaking, allowing hot exhaust gas to escape from the exhaust system. Depending on the location of the break or leak, hot exhaust gas may be directed toward the main wiring harness and/ or the SCR (Selective Catalytic Reduction) dosing valve assembly. This heat exposure can result in: • Internal melting of wiring insulation within the harness • Short to ground conditions and loss of communication between control units • Damage to the dosing valve and/or heated AdBlue line Damage to the wiring harness may not be visible externally, as the outer tape can remain intact while the internal wires are melted and fused together. Remedy Inspect the DPF assembly for cracks, separation, or leakage. Do not proceed with further diagnosis or component replacement until the exhaust leak source has been identified and confirmed. If any damage is found, replace the DPF filter assembly. Based on the location of the failure, inspect all components in the path of the exhaust leak, including the dosing valve assembly and main wiring harness. The wiring harness must be opened in any area exposed to the exhaust leak to visually inspect the individual wires. External inspection alone is not sufficient to determine harness condition. Repair or replace any damaged wiring in accordance with approved repair procedures. Replace any dosing system components that show signs of heat damage. Failure to identify and repair all heat-affected components will result in repeat faults or no-start conditions.

Check engine light on and FC P146264 stored in engine and fuel pump control units Complaint Check engine light active and FC P146264 Temp. and pressure sensor B4/15 is stored in Engine control unit and Fuel pump control unit. Cause Software parameter in Fuel pump control unit. Remedy Update fuel pump control unit (FSCU) to software version A0009024488 A0009030664. Clear fault codes and check for any additional symptoms.

Complaint Transmission control unit Y3/8n4 (fully integrated transmission control unit (VGS)) not listed in quick test and/or no communication possible with VGS. Cause Transmission control unit Y3/8n4 Remedy For vehicles with 722.9 transmission: Ensure LI54.15-P-057373 is performed before replacing any component parts. After processing and complying with the above document(s): 1. Perform an ignition reset on Y3/8n4 (VGS) 2. Inspect transmission connector for loose connections, damaged wiring or pins and any other concerns. If communication with the VGS cannot be established, the complete valve body ('electrohydraulic controller unit (EHS)') must be replaced. Installation of a VGS repair kit is not permitted in this case as it is not possible to transfer the necessary valve characteristics without communication with the original control unit.
