After one year of ownership, purchased used from dealer with 40 miles) I have to replace control unit due to the location of the unit in the car developing mold from condensation. Is a common problem, is widely discussed on the internet, and mbz does not cover under warranty. The repair is to replace the unit ($2,700 in labor/parts) and place a plastic bag over the new unit.

Code p052e-71 valve for crankcase ventilation has a malfunction code p06da-00 actuation of the valve in the combustion engine has an electrical fault or open circuit. These codes have been reported on too many times on forums to not have these issues recalled and fixed and paid for by mercedes. This expensive problem should not have occurred with such little mileage and have to be fixed by the consumer.

Check engine light checked and diagnostic code p052e71 showed that the valve for crankcase ventilation has a malfunction. The actuator is blocked, p06da00 the actuation of the valve of the oil pump in the combustion engine has an electrical fault or open circuit. The problem is prolific on the Metris vans and the repair costs extremely high for such a lemon sensor and can cause catastrophic failure and damage to the engine.

The wiring harness for the seatbelt pretensioner wore through in its normal factory installed location and shorted out, causing the air bag light to come on. No modifications have ever been done to the vehicle to disturb this path and causing wire chafing. It is highly doubtful the pretensioner would have worked either, as 3 out of the 4 wires had their insulation worn through. This was diagnosed by the dealership and video of the issue was provided at https://r7788463. M. Reyrey. Net/app/?ref=ao9xdmndqtsq554czq1dqg%3d%3d&sys=e1b63ec6-8626-424a-b7a7-80e9ade1db58 I have had this fixed, but the text messages with the dealership lead me to believe that this is not the first time they have seen and repaired the issue.

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.

Electrical failure by mercedes Metris is intermittent but frequent. There are multiple times where car will indicate that blind spot alert is inoperable. Similarly, it appears that indicator on same side and automatic door locks on that side do not work. It will sometimes reboot and work intermittently for a period of time before recurring.

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.

I have been trying for 5 months to get this fixed from the dealer and or manufacturer. They still state they dont have the parts or something . Its been to long and this is a serious safety hazrd to not be able to use the back up camera correctly . We are not even using the vehicle at this time .

Two failures of wheel speed sensors. Right front was first and just caused the computer to shut down anti lock breaking system. Most recent was left rear and caused transimission to go into “limp”.

Rearview camera broken.

Battery caught fire and melted down. Vehicle was driven for about 2. 5-3hrs on 12/26 and then parked for 2 hrs, when I went to start vehicle it was totally dead, all electronics black and car would not turn over, I then notices a small amount of smoke coming from passenger seat where battery is stored. I exited the vehicle thinking it was just a small short and would have it towed. I then noticed smoke billowing out of vehicle so called 911 and fire dept came out, battery was literally melting, the firemen were able to discconect battery and stop the meltdown preventing the car from going up in flames, I can only imagine what would have happened while driving.

The rearview camera froze while I was backing up. By "froze" I meant the picture became static while the van was moving back. This is very dangerous because it will mislead the driver on what's or what's not on the path of moving direction. The issue persist when I moved the car back and forth. It went away after parking the van in garage for a few hours. I am very concerned that it may happen again and may cause serious accidence.

I have a 2016 Metris passenger van with 14000 miles that the mechanical/analog speedometer shows incorrect speed sometimes. It only happens after the van has been traveling with speeds over 60 mph + I notice the speedometer showing about a 20 mph slower speed, then over a few min. The speed slowly keeps dropping until 0 mph. The total time to 0 mph is about 15 min. After coming to a complete stop the speedometer functions properly. Only the mechanical speedometer is affected, the digital displays correct speed. This has happened 10 times that I know of.
