The 2010MERCURYMARINER carries 393 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 4 crashes, 4 fires, 12 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2010 MARINER is vehicle speed control with 66 filings, followed by engine (61) and steering (59). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 3 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 22 investigation files overlapping the 2010 MARINER. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

Power Steering assist fault went out with no warning. Now steering wheel is locking up while driving. Also when trying to gain speed the vehicle bogs out.
Engine light came on after putting fuel in my car it is hapless the codes read emission and fuel issues to replace cap but it is hapless it says it's an issue that needs to be fixed now my engine light won't go off
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.

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.

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.
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.
