P052E PCV valve issue, as for many others, this part malfunctioned about a month after warranty has expired. This seems to be a known issue for this model (GLC300) according to many online forums.

From the beginning, I have had issues with my car and received nothing but patronizing responses from both the dealership and the service department. From the very start, I have experienced constant issues with my car, only to be met with a condescending attitude from all levels of senior staff members at the dealership and the service department. When I asked for solutions, their solution was to inform me that I was merely using my car door handle incorrectly to open it and activate keyless go. The repair department refused to acknowledge any mechanical faults and instead blamed me as the operator although I had no issues with operating any of their loaner vehicles. Mr. Max Spata eventually arranged one last attempt at repair, yet I was immediately denied service after the service department eventually received notice of my legal letter asserting my rights under the contract. Instead of making an attempt to remedy the solution as requested in that letter, the service department called and advised me that they were demanding the return of the loaner vehicle and that I must pick up my vehicle immediately. The service department then subsequently refused to make any attempts to repair the vehicle under warranty and have continuously made me feel as if my issues are invalid. Throughout the entire process, I have felt invalidated and belittled by their attempts to gaslight me in order to avoid responsibility for their faulty product. The vehicle has experienced several malfunctions, including but not limited to, the KeylessvGo Entry malfunctioning while attempting to enter the car, the vehicle locking without beingvprompted, and the vehicle failing to recognize when keys are inside, thus not allowing it to operate. Moreover, there have been several audio/muffled sound issues with the vehicle's radio system, which have significantly impacted my driving experience. Additionally, I have experienced a recurring problem of the vehicle locking the keys inside the car.

Hello, I own a 2019 Mercedes Benz GLC 300 that's been on recall with no remedies released since April of this year. The recall is a SIM module defect that is suppose to help the driver get ahold of emergency responders in case an accident were to happen. The remedy is suppose to be OTA, but I have not seen anything update on my vehicle and I am worried Mercedes is going to forget about this update.
