The vehicle has a severe brake fluid leak. There is a recall for the issue. I called the local Lincoln dealership Ford Mill Lincoln SC and they said there was nothing they could do. I explained to them that there was a safety recall. They refused to fix the vehicle under the recall. The car is very unsafe to drive and the manufacturer is not offering any assistance to fix the defect.

problem is when you go to check the oil do you think youâre gonna find a low oil situation and what happens is the oil is actually overfilled however itâs not overfilled because you put too much oil in it. Itâs overfilled because gasoline is leaking into the oil pan. So the oil is diluted and it actually doesnât even seem like oil. It seems like dirty gas. Thatâs 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. Supposedly the fix is either changing the fuel pump or fixing the valves or maybe a combination of both either way…

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…
