On May 22, 2025, while parked, my 2019 Mercedes-Benz GLC300 spontaneously caught fire, completely destroying the vehicle. Thankfully, no one was inside, and no injuries occurred, but the property damage was significant. I later discovered Recall 21V961000 / Campaign 2022030003 affecting some 2019 GLC300s for fuel leaks at the fuel rail/injector interface, which pose a serious fire hazard. Further research has shown reports of loose ground connections in these vehicles as well, increasing the risk of sparks igniting leaked fuel. Given that my vehicle caught fire spontaneously and matches the defect described in this recall, I firmly believe this incident was related to that defect. Mercedes-Benz has not provided adequate assistance. The vehicle was towed to a local dealership (Plaza Mercedes-Benz), but they refused to accept it, adding further confusion and hardship. I am submitting this report to request that NHTSA fully investigate this issue and work to ensure that Mercedes-Benz USA takes responsibility for this vehicle defect and compensates me for this dangerous failure. I am happy to provide photos, tow reports, or further documentation if needed. Thank you for your assistance in ensuring public safety.

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.
