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

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.

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.

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.

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.

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.

Mercedes claimes that the Metris is able to tow 5000lbs. We bought the vehicle new with the tow package factory installed. Mercedes never disclosed the fact that it's wiring harness included in the package does not operate electric trailer brakes and that no factory or third party option is available. We almost had an accident due to our inability to stop quickly enough. Thats how we found out that the factory installed trailer wiring harness does not operate electric brakes. Mercedes should have warned us about this issue. The factory trailer wiring harness includes a 7 wire connector, but is only wired for 6. it controls brake lights, turn signals, running lights but not electric brakes. I filed a complaint with Mercedes corporate and stated how this is a safety issue. Customers may wrongly assume that their electric trailer brakes are being activated when applying the vehicles brakes. Without trailer brakes, most tow payloads are limited to 2500lbs. 5000lbs is way beyond the safe limit. Mercedes stated that there is no way for the Metris to activate electric brakes. I believe that Mercedes needs to warn customers of this specific design flaw. Most light duty trailers and campers in the usa use electric brakes. Our almost accident happened on the I35 South of waco tx. We were at highway speed when the traffic came to a sudden stop. Luckily we had a large enough distance between us and the cars stopping ahead. We had a car at the last moment swerve into our lane and stop. Now we were trying to come to an emergency stop. We had to depart our lane to keep from rear ending the car. We later found out that our trailer brake we not being activated and that was the cause of our increased stopping distance.
