ELECTRICAL SYSTEM, ENGINE, UNKNOWN OR OTHER
Me and my wife purchased a vehicle from a private seller to use for personal commute. A month later we started to notice more issue were occurring with the car then stated from the seller. I took it to an auto body shop to get it inspected and possibly serviced and upon that inspection the clerk stated that there was a milage adjustment done to the vehicle. We contacted the seller to try and return the vehicle and receive our money back, but the dealer refused and requested us to resell it.

STEERING
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.

FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
My vehicle keeps throwing codes for the EVAP system. I have noticed many of these vehicles have to have their Purge Valve Cannister replaced along with the selenoid for it. I have to replace mine. Is that not a defect if the vehicle? I have owned several vehicles and never had this issue with any of them.

FUEL/PROPULSION SYSTEM
I bought a 2010 Mercury Mariner on June 22, 2023 from a local dealer. There are several recalls associated with the make and model of the vehicle, but they do not appear to be associated with the VIN on my vehicle. However, the recalls on the vehicle appear to be affecting my vehicle and there is a warning on the dashboard of my car about the fuel system which is one of the recalls on the vehicle. Fuel Delivery System is causing issues in my vehicle.

FUEL/PROPULSION SYSTEM, SUSPENSION, STEERING
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.

SERVICE BRAKES
Driving downhill after dropping my children off at school heard a loud popping noise and brake pedal fell to the floor. Total loss of brakes. Coasted to the side off the road narrowly avoiding busy intersection. Vehicle was looked at by mechanic, traced to faulty ABS Sensor. Serious safety hazard— Recall must be issued immediately to prevent accidents and injuries!

SERVICE BRAKES
Brake pedal went to floor on my 10 Mariner, slid into intersection, no warning lights came on, checked for any fluid leaks and there were none. This is 2nd time it has happened and is extremely dangerous! Believe, like others that it is the ABS control. Ford should fix this immediately!

ENGINE, ELECTRICAL SYSTEM
When the weather is hot (close to 100 degrees or more) and I am driving with the a/c - my vehicle on 3 occasions will not start after parking the vehicle and trying to restart it. The red padlock sign blinks and it won't start. At first it is trying to turnover but then will continually sound worse and all other warning lights go haywire. I leave the car alone for half a day and it starts up again like nothing happened. On the fourth occasion, the car stopped while driving, just a quiet shutdown and the car glided. This time it did not work for over 24 hours and then started up again like nothing happened. Multiple mechanics and also the dealership cannot figure out the problem because by the time i have it towed to shop, it works again. They did a full check on the car and cannot find anything wrong and there were no diagnostic codes. This issue happens when the weather is hot and poses a safety concern as now it is shutting off while driving and I become stranded each time. (First incident happened 8/25/18, last incident 5/14/22) Total of 4.

FUEL/PROPULSION SYSTEM
My vehicle has been running out of gas extremely quick. It also leaks underneath when I am pumping gas into the Mariner. I am having a loud thunking sound underneath the vehicle an when I let off the accelerator, my car slowly comes to a hault. My power steering went out one day also without warning. I can't figure the problem out except I seen a recall for the power steering module or some sort that has malfunctioned an causes the computer to erase the power steering sensor completely clean of it's existence. Please help!
