“We have a 2012 Ford FLEX normally aspirated engine. Starting in august, we had an issue with our electronic throttle body which caused our car to shut down. We had the part replaced, shortly after a similar problem occurred. This was due to the dealership frying the computer. This was replaced, by the dealership, after calling Ford directly. In february, the electronic throttle body failed again. Replaced under warranty. The same issue occurred last night and the vehicle will be taken back to the dealership. All signs point toward the electronic throttle body again. …”
