2015 MERCEDES-BENZ SLK250 Complaints
I am submitting this complaint to report a serious high-pressure fuel system failure on my 2015 Mercedes-Benz SLK 250 equipped with the M274 2.0L turbocharged engine, which resulted in a sudden and dangerous loss of propulsion. While accelerating to pass another vehicle at roadway speed, the engine abruptly lost power, stalled, and the vehicle immediately entered limp mode, leaving me exposed to active traffic with no warning and unable to complete the maneuver safely. The incident triggered diagnostic fault code P000277, consistent with a fuel pressure or fuel control system malfunction. This failure created an immediate safety hazard, as loss of engine power during acceleration significantly increases the risk of rear-end or side-impact collisions. Of particular concern is that Mercedes-Benz has previously acknowledged fuel system safety defects in the same M274 engine family, as documented in NHTSA Safety Recall Campaign No. 18V-837, which addressed known vulnerabilities in the fuel delivery system that could lead to engine malfunction. Although my specific vehicle may not have been included in that recall, the symptoms and failure mode I experienced are consistent with those known fuel system issues. A sudden and complete loss of engine power during normal driving conditions represents an unreasonable risk to motor vehicle safety. I respectfully urge NHTSA to investigate this failure pattern to determine whether additional vehicles using this engine platform are affected and to take appropriate action to prevent injuries or fatalities. Can you please give me a document so I can go to Mercedes and get this fixed? this first happened in June 2024 and I am since clearing the code myself and I just found out this problem.;
