SEAT BELTS
Issue: Front driver and passenger seat belts do not fully retract despite completed recall service. The seatbelts often "puddle" behind the seats when unbuckled, and sometimes get trapped between their seat and adjacent door. My car was recalled and serviced under Mercedes Campaign 2021020010 to fix this in October 2021. Also, the right front seatbelt was replaced in October, 2018 under Campaign 2017050023. The first paragraph of the Mercedes Recall Campaign Bulletin states, "...certain C-Class Cabriolet vehicles (A205 platform) with PRE-SAFE might not meet the requirements of FMVSS 208, S7.4.5., as the front seat belts might not fully retract to its stowed position. In this case, certain regulatory requirements under FMVSS 208 might not be fulfilled. If the seatbelt webbing does not fully retract into its stowed position, the consumer may find the operation of the seatbelt inconvenient and not wear it, increasing the risk of injury in the event of a crash." In its step 1, the bulletin states, "The seat belt strap must retract into its final position automatically. Provide manual assistance with rolling up the seat belt strap if necessary." Having to provide manual assistance to retract the seat belt does not meet the definition of "must retract into its final position automatically". Further, it does not meet the aim stated in the bulletin's first paragraph about the importance of the seat belt fully retracting. The labor time spent on campaign was only 0.10 hours (6 minutes), so nothing more than a cursory inspection was done, and not any actual service work. I spoke with my local Mercedes dealer and the Mercedes USA customer service rep. They are both Ok with manually feeding the seatbelt into its slot. This is unacceptable and does not meet FMVSS 208. Both the dealer and the Mercedes USA say I can pursue proper fix at my expense. This is a failed recall service and I should not have to pay to explore a proper remedy.

ENGINE, FUEL/PROPULSION SYSTEM
Diagnosis code P052E PCV regulator valve replacement/crankcase replacement. Dealership does not want to acknowledge code while car was under warranty despite proof that it existed when check engine was diagnosed. Now code keeps coming back with check engine light on dashboard. To replace part, the engine has to be taken down since the crankcase is inside the engine. This is a malfunction during assembly/manufacturing, it is impossible to damage part while under usage. Mercedes Benz should be held responsible for part replacement and labor. I urge you to investigate this matter with other clients and ask the manufacturer to replace part and pay for labor.

ENGINE, POWER TRAIN, FUEL/PROPULSION SYSTEM
At approximately 26,500 miles of use, the check engine light came on in my Mercedes Benz C300. I brought the vehicle to the dealership and they informed me that the diagnosis was a crankcase vent valve malfunction. The MB fault code is P52E71. After paying Mercedes to fix the issue, I found forums on the internet where many other MB owners reported the same issue at around the same mileage. Being that this seems to be a common malfunction with the C300, I believe that it should be considered as a recall issue. I don't know what could have happened if I didn't service the vehicle, but any engine issue is dangerous while a vehicle is in motion.

UNKNOWN OR OTHER
I’m trying to ship my car back to the United States and there is a valid recall on my car which I have taken it to the dealership in Korea, which is where I’m currently at, and I cannot get me car updated either because they don’t understand the paper or because I don’t have an official recall which I have also encountered in the states. Without this update my car will not be shipped back home with me. Is there any way I can get this recall information in Korean to possibly make them perform the update.
