Open the full vehicle complaint log (all categories)The throttle body went bad while driving 55mph and 35mph. Over 5 times I could not accelerate while stepping on the gas peddle and it would stall out trying to get it to ford on the same road for 5 miles. I had to quickly stop and turn it back on with my flashers going less than 35mp on a 55mph road. This happened at first going around a corner you can not stop on due to no visual on the other side which would cause a wreck stopping there. The problem was confirmed by Coughlin of Heath Ford and they were the ones that fixed it. There was no warning of the throttle body going bad until it happened at that moment and repeated to happen as I tried to get it to ford on the same road it was happening on into town. The check engine light did come on but it it would go on and off during the situation until it finally stayed on after a few minutes. There is a photo of the report attached to this document.
I’m a snowbird and in the past 18 months, of which I was in Iowa for 12 months of this time, the dealership has replaced the fuel pump five times. I’m scared to take this vehicle out on the highway. The module that controls the fuel pump has been replaced once. The third replacement I didn’t even get off the dealers lot before it quit
