NHTSA Complaint #11549631 — 2017 FORD EXPLORER

While driving cross country, driver began to experience lag in acceleration and delayed shifting. In some cases, noted transmission was not down shifting. At destination, the check engine light came on and we took the vehicle into a Ford dealership for repair. It should be noted that there was a low coolant light just prior to the trip and we filled up approximately a quart to bring it back to serviceable limits. The dealer called after several hours to explain the car would need a new 2.3L EcoBoost engine and new Automatic transmission. The engine had evidence of coolant in the engine/oil. The transmission was diagnosed to have a failure of an internal component. The vehicle was been regularly serviced for the 79000 miles with no previous warning lights. We currently have the vehicle in our garage trying to decide if it's worth fixing for $25000 quoted by the dealer.
