The 2008 Mercury Mariner page works best as a research starting point. Complaint totals show how much owner-reported activity exists, while recalls and investigations help show whether any of that activity turned into formal safety action.
Because this is a newer-era vehicle page, it usually helps to compare this year against nearby model years before deciding whether a complaint pattern looks isolated or persistent. On this page, the most prominent complaint area is steering with 262 reported complaints.
This page combines three types of NHTSA data: recall campaigns (official manufacturer or government actions), owner complaints (unverified consumer reports), and crash test ratings (where available). A vehicle with many complaints is not necessarily less reliable — complaint volume correlates with sales volume and vehicle age. Recalls indicate identified defects, not overall quality. To compare this model year with others, use the year navigation in the sidebar or return to the model overview page.
If you are researching a used vehicle, start with the complaint categories, compare them against the recall list, and then check nearby model years to see whether the same issue profile repeats. That usually produces a better buying or research signal than treating the raw complaint total as a standalone safety ranking.
Ford Motor Company (Ford) is recalling certain model year 2001-2008 Ford Escape and Mercury Mariner vehicles manufactured March 31, 2001, to September 1, 2009. The affected vehicles are equipped with either a 2.3L or 3.0L engine and have had their CD4E transmission replaced with remanufactured one that was rebuilt between June 11, 2015 through July 15, 2015. These service repair part transmissions have a shift lever bolt that may not be properly tightened. As a result, the shift control lever could disengage from the transmission without warning.
Remedy Status
Ford will notify owners, and dealers will inspect the transmissions and either tighten the manual shift lever bolt or replace the manual shift lever assembly. These repairs will be performed free of charge. The recall began on October 23, 2015. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 15S28.
The Timken Company (Timken) is recalling certain aftermarket front wheel bearings, part number 510072, sold from January 22, 2015, to May 21, 2015, to be used as service parts on 2001-2012 Ford Escape, 2001-2011 Mazda Tribute, and 2005-2011 Mercury Mariner vehicles. The affected wheel bearings have incorrect dimensions of a 42mm bore, 76mm outer dimension, and 39mm width, instead of a 42mm bore, 78mm outer dimension and a 45mm width.
Remedy Status
Timken has begun notifying distributors who will offer purchasers replacement wheel bearings, free of charge. The recall began on May 21, 2015. Owners may contact Timken customer service at 1-866-984-6536.

Remedy Status
Ford will notify owners, and dealers will update the software for the power steering control module (PSCM) and the instrument cluster module, free of charge. If a vehicle shows a history of a loss of the torque sensor signal or fault codes relating to the PSCM when the vehicle is brought in for the recall remedy, the affected components will be replaced, free of charge.
