“The power steering assist is malfunctioning and it is available for inspection upon request. The steering wheel is very difficult to turn, it's as if the power steering assist is keeping the wheel from turning. No, but I spoke to someone at Ford and they said that it sounded like my car should be in the recall that was announced for my vehicle type but my VIN was not included in the recall. My car has not been inspected by anyone but it says right on the dash board digital display that there is a "Power Steering Assist Fault". Ford does this with many vehicles they recall, a lot of vehicles that should be included in the recalls are not and we're supposed to foot the bill for their lack of concern for public safety? It's going to cause an accident but it's my only working car and I can't afford to pay for their mistakes. How many have died due to their negligence I'm wondering.”

“I recently purchase 2010 Mercury Mariner. There is a few errors appearing on the screen in front of the steering wheel. One of the error is "CHECK FUEL LINES." It also has an error about the tire pressure sensor. It also rides roughly, but the wheels are like new, so it feels like the suspension or shocks have something wrong with them. Also, there is a lot of play in the steering wheel when driving it. When I went to check on the recalls in the system by putting in my VIN, it shows that there are no recalls on my vehicle. However, these errors and issues are connected to the recalls for my vehicle. I am sure that these recalls have not been taken care of for this vehicle and they need to be fixed.”
