I have a MC Benz 300 GLC with $50,000 miles. I was having heating issues so took it to the dealership, which basically advised of the issue describer below, which would cost $14k to repair. Contaminated coolant in Mercedes-Benz GLC 300 models often results from the internal failure of a "desiccant bag" inside the coolant expansion tank, which disintegrates, releasing material that clogs the heater core. Symptoms include black residue in the tank, reduced cabin heat, and engine overheating. Key actions include replacing the expansion tank (reservoir) and flushing the entire system.

My sunroof just exploded while driving on the highway without any impact or warning. It was a clear sunny day. There wasn't a vehicle in front of me. Nothing fell on my windshield nor sunroof. The sudden explosion and shattering of the glass was extremely startling. I had a mesh underneath the sunroof that contained some of the shattered glass so it did not fall on me while I was driving. I'm so thankful there wasn't a car behind me for the glass debris to fall on. Mercedes USA was not helpful, unresponsive for many weeks. They eventually declined repair coverage due to out of warranty, not manufacture defect nor safety issue.

Sunroof exploded while I was driving. No other cars around me, pretty day, not a very hot day. I’m driving along and suddenly hear a loud POP that sounded like a shotgun going off! I swerved, but thankfully did not leave the road. Shattered glass was contained in the cover of the sunroof as I didn’t have it open at the time. A huge hole is in my roof of my car! I called the dealership who said it was not covered under any warranty although I just got the vehicle in Feb of this year. He said I would have to contact corporate. I contacted corporate who said bring it in for an inspection. At the conclusion of the inspection on 10/8/24, they could not determine if it was a manufacturer defect or outside sources since they could not find a point of impact, because the glass was nearly all gone. I had to get my insurance involved. There was no warning whatsoever. The dealership said no recalls. It just exploded all of a sudden!

The error code is P052E and it is a PCV Code Crankcase Ventilation Oil Separator. It's a time-consuming and expensive repair that seems to be regularly occurring on a lot Mercedes Benz that have this installed. And it happens often on cars with under 50K miles on them and when it's just been out of warranty this is a small inexpensive part that the customer funds through the cost of labor. Not that mechanics don't deserve their labor costs, but Mercedes ought to fix this is issue as it is borne by the consumer of a high end vehicle for a consistent, faulty part that they have engineered.

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.
