This is related to recall #25V-481. A Mercedes Benz dealer (Mercedes Benz of Loveland) is refusing to complete the recall fix issued to my vehicle, even though I have the safety notice letter with my VIN. In conditions where the charge on the house batteries is low, the secondary alternator activates while the engine may be in a low idle state which can cause the engine to stall. The gas pedal can be pushed to the floor with no effect. This happened on the highway with the result being cars having to emergency avoid behind me.
