Example complaints

Electrical system: “We are currently under NHTSA Recall ID: 26V073 and Mercedes-Benz has not given us a reasonable timeline with which they intend to remedy the recall. We are currently unable to drive the car safely and unable to park the car safely without the risk of fire. To not have any answers as to when this recall will be remedied is unacceptable.”

NHTSA complaint #11728360, filed 2026-03

Fuel system: “Mercedes previously issued a software update for the battery fire risk, but we have received a letter more than a year later stating that this fix was not adequate. We pursued a vehicle buyback due to the safety risk this presents to my family, and Mercedes vehemently stated that the issue was resolved and the vehicle did not qualify. The vehicle is an inherent risk to my family's safety if it may just catch fire at any time.”

NHTSA complaint #11726005, filed 2026-03

The messages “Reduced Drive System Performance and Towing not Permitted were displayed. The accelerator pedal was depressed; however, the vehicle failed to respond as needed and stalled. …”

NHTSA complaint #11690713, filed 2025-10, 115,000 miles

Transmission and drivetrain: “he vehicle intermittently fails to shift from Park (P) to Drive (D). Recently, the car was completely immobilized for over 6 hours because the gear would not engage, making it dangerous and unpredictable to drive. Additionally, the vehicle has experienced multiple charging failures where charging repeatedly cuts off unexpectedly. A formal diagnosis from Mercedes-Benz of Cary confirmed a front axle drive unit failure and high-voltage insulation faults, triggering codes U041A00 and P154800. …”
