Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2011 MARINER is power train with 24 filings, followed by fuel/propulsion system (22) and steering (19). 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 2011 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.

While my wife was driving the vehicle, the power assisted steering failed and produced a "power assist fault code" on the display. The car became too hard for a 74 year old woman to be able to steer. I took the car to the Ford dealer near me who confirmed it was the steering torque sensor had failed and needed to order in one and would cost $600 to replace. I did a VIN search on your data base, but it didn't show any recalls for this problem. However a google search showed a recall for my vehicle make, model and date of manufacturer and part of the Ford 14SO5 recall. The information on your web site shows that Mercury Mariners manufactured prior to Sept.11, 2010 were affected. Mine was manufactured in August of 2010. According to the Ford notices as published on your web site my car should be part of that recall and should receive a software update that would prevent the steering assist from being turned off. The Ford dealer is refusing to do the update and sensor replacement for free

This car has excessive under body rust under all the wheels wells. I was just told that my car would not pass a State Inspection because the on the front drivers side there is a bracket that holds up the engine is almost totally gone. I have read and over that this vehicle has a known rust and corrosion issue and Mercury/Ford has not been made responsible. I bought this car from a Ford Dealer in Aberdeen, MD used in 2018 and made them aware that I noticed rust on the rear wheel panels. They told me there is no recall however now I am not in a position to purchase or fix the entire under carriage of this vehicle. And I do not feel safe that an important bracket supporting the engine is totally rusted out.
