“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”

NHTSA complaint #11630287, filed 2024-12

“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. …”

“problem is when you go to check the oil do you think you’re gonna find a low oil situation and what happens is the oil is actually overfilled however it’s not overfilled because you put too much oil in it. It’s overfilled because gasoline is leaking into the oil pan. So the oil is diluted and it actually doesn’t even seem like oil. It seems like dirty gas. That’s how much gas gets into it. Supposedly this is a known issue after searching it on the Internet, this is known, and it happens with this making my vehicle. The manufacturer should be responsible for fixing it. …”
