ENGINE
Crankcase Ventilation Valve malfunction at under 50k. Check engine light is on and I took it into the shop after gas fumes were coming into the car through the ventilation system. I was informed that has been an ongoing issue with Mercedes and I was referred to fill out this document to try and kickstart a recall process. This is a problem that is very costly, and seemingly is happening to most recent models at around the 50k mark. Beyond that is is also a safety hazard as it is causing gas fumes to enter the cabin of the vehicle.

ENGINE
CEL on, P052e code for crankcase ventilation/PCV failure. Vehicle has about 55k miles. Extremely common failure on these vehicles at this mileage and expensive/complicated to repair. Will not pass state emissions because of this. Given extensive anecdotal evidence of the pervasiveness of this problem, recall should be issue.

POWER TRAIN
I have owned the vehicle for only about 4 months. My wife took the car out for a short errand and returned to tell me that the engine light was on. I took the vehicle to AutoZone and had the code ran on their diagnostic computer and it returned a P052E code for “Positve Crankcase Ventilation Regulation Valve Performance”. I have done a lot of research and have learned that this is a common problem and incurs huge financial impact to unsuspecting buyers. Mercedes has even made improvements to the part because of this issue. It’s not safe due to the possibility of oxygen build occurring in the combustion chamber. This part should be recalled and repaired by Mercedes.

UNKNOWN OR OTHER, STRUCTURE:BODY
the Burl wood trim panel on the interior doors are deteriorating , the drivers side panel is deteriorating to the point that it looks like acid is eating away at the material there is red markings showing .. i find this could be a safety hazard as it could eat away at the door itself. i have pictures of evidence. there was a recall on Mercedes E class during the same years i purchased my car, my car is the C-class which was not part of the recall, but falls into the same category as time frame of purchase. Mercedes told me to contact you. i look forward to your response as this is a safety concern thank you
