“The Power Electronics Control Unit (ECM), Part No. A453-900-72-11, and the DC-to-DC converter have both failed, rendering this all-electric vehicle completely inoperable. There is no backup propulsion system. The DC-to-DC converter powers safety-critical systems including lighting, turn signals, and hazard flashers — its failure could cause loss of safety-critical functions while driving. Total repair estimate is $20,560.43. The manufacturer Mercedes-Benz USA denied warranty coverage using a Canadian warranty document for the wrong vehicle model. …”
