2020 Acura MDX Fuel System Problems

Auto idle cuts off idling at stop light but when reengaged stalls the car completely. Must totally restart car before continuing causing back up in intersection and almost being hit. Happened several times, when I forget to turn auto idle off. New battery did not help

While driving on the highway, at highway speeds, all dash lights came on and the vehicle immediately lost power coming to an abrupt stop. We were able to limp the car to the side of the road. It was ultimately determined that the car’s fuel pump had gone out. The fuel pump was replaced by Acura, and covered under the initial manufactures warranty. However, it’s rather suspicious that our car is not included in the recall given that the fuel pump failure is identical to the open recall for our same make and model.
