Every safety complaint, recall and defect investigation the US government
holds on this vehicle.
Owners have filed 9 safety complaints
about the 2010 Mercury Mariner Hybrid with the US government. Of those, 1 describes a crash and no death is recorded. No recall campaign has been matched to this year, make and model.
The most complained-about system is vehicle speed control,
named in 3 complaints, 33% of the total.
The typical failure was reported at 59,250 miles,
the median across the 8
complaints that gave
an odometer reading.

A complaint is an unverified account by the person who filed it, not a
finding of fault. One complaint is one ODI number, which is how NHTSA counts
them.
No recall campaign was matched to this year, make and model. That is not
the same as a clean vehicle: recalls are issued against production
ranges, and the only reliable check is your own VIN.

One complaint can name several systems, so these add up to more than 9.

Crash test ratings
NHTSA New Car Assessment Program
NHTSA crashes a car into a barrier and a pole and measures what
happens to the dummies inside. This is what it awarded the 2010 Mercury MARINER HYBRID, and it is a separate
question from what owners report going wrong later.

NHTSA made its frontal crash test harder for the 2011 model year, and says ratings from before that change should not be compared with ratings after it.
A dash means NHTSA did not rate that test for this vehicle.
Defect investigations
2 on file
An investigation means NHTSA has decided a pattern is worth examining. A
preliminary evaluation is often closed with no action; an engineering
analysis is the stage that usually precedes a recall.

the electrical system
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.
Loss of power steering while driving

Closed defect petition · opened April 1, 2015 · closed June 14, 2018
the steering
On May 27, 2014, amended June 2, 2014, Ford Motor Company (Ford) submitted a Defect Information Report (DIR) to NHTSA describing a safety defect that may result in a sudden loss of power steering assist while driving in approximately 746,067 model year (MY) 2008 through 2011 Ford Escape vehicles equipped with electric power assisted steering (NHTSA 14V-284, Ford 14S05). Ford's DIR described the defect condition as a poor signal to noise ratio [SNR] in the torque sensor within the Electric Power Assisted Steering (EPAS) system [which] does not allow the PSCM to determine the driver's steering input. When the system detects this fault condition, it transitions the EPAS system to the fail-safe/manual steering mode.Ford's DIR indicates that loss of power steering assist while driving would require higher steering effort at lower vehicle speeds, which may result in an increased risk of a crash.Ford's remedy instructs dealers to check the Power Steering Control Module (PSCM) for Diagnostic Trouble Codes (DTCs) to determine the proper repair procedure. If no DTCs are present, dealers are to update the PSCM and instrument cluster module software. The updated PSCM software changes the torque sensor fault strategy so that the SNR condition does not result in a loss of power steering assist while driving.In addition, audible and visual warnings are provided for torque sensor faults.If DTCs indicating faults in the torque sensor, PSCM or Power Steering Motor (motor) are present in the initial recall inspection, the dealer performs the following repairs: 1) replaces the torque sensor for torque sensor faults (DTC B2278); or 2) replaces the steering column for faults related to the PSCM (DTC B1342) or motor (DTC B2277).Continued in attachment pages

MY AIRBAGS DID NOT INFLATE AND I IMPACTED THE STEERING WHEEL SO HARD I BROKE THE STEERING COLUMN OFF THE DASHBOARD. 3 DAYS IN THE HOSPITAL WITH A COMPRESSED CHEST, IMPAIRED BREATHING, AND MASSIVE BRUISES. I HAD A COLD AT THE TIME AND IT MADE RECOVERY SLOWER. *TR

If this is your car and a dealer keeps failing to fix it, your state's
lemon law may require the manufacturer to replace it or buy it back. How
many repair attempts it takes, and how long you have to file, is set by
the state you bought in and by nothing on this page.

A complaint is one owner's account and has not been verified by NHTSA or by
us. A vehicle with more complaints is not necessarily worse: models that
sold in larger numbers collect more of them. How this is counted.
