The Mercury Mariner, produced by the now-defunct Mercury division of Ford Motor Company, was a compact crossover SUV and Mercury's inaugural car-based SUV. Introduced in 2005, the Mariner was marketed primarily in the US, Mexico, Middle East, and earned recognition such as the Consumers Digest Best Buy for three consecutive years, and the Mariner Hybrid was named 2006 Green Car of the Year. The Mariner was notable for being the first Mercury to feature a four-cylinder engine since the discontinuation of the Mercury Cougar in 2002. Over its two generations, the Mariner saw a series of improvements. It was initially 4,442 mm long and 1,781 mm wide, but became larger in the second generation, featuring a redesigned interior with high-quality auto parts and new features, and an updated exterior, including new seats, headlights, doors, and wheels. It was powered by a 3.0L Duratec V6 engine, with its hybrid version introduced in 2006. Notably, the Mariner, along with the Ford Escape, was the first to showcase pull-drift steering compensation. The 2009 model saw further enhancements with a 2.5-liter engine and a 6-speed automatic transmission, resulting in improved fuel economy and an output of 170 horsepower. As for its 2010 model, it added Flex-Fuel capabilities, and the 2011 model introduced HD Radio, a strong selling point being the Sync system. Production of the Mercury Mariner ceased on October 5, 2010.
The Mercury Mariner, spanning models from 2005 to 2010, confronted two prominent issues: power steering malfunctions and transmission failures. For the 2008, 2009, and 2010 models, the recurrent power steering dilemma manifested as an erratic loss, predominantly during low-speed tight turns. This problem was frequently linked to the power steering control module (PSCM) housed in the steering column. A 2014 recall attempted to rectify this through a software update, but the absence of a comprehensive hardware solution meant that numerous vehicles, even those seen during the recall, still grappled with the issue. Compounding this concern, certain Mariners, based on their VINs, were excluded from the recall, imposing both financial and safety burdens on the owners. Specifically, the 2008 model's power steering could falter even with proper fluid levels, often due to a flawed Steering Shaft Torque Sensor. To diagnose this, a Power Steering Control Module scan is imperative, with the B2278 code typically signifying a sensor issue warranting replacement. In parallel, the Mariner, especially the 2006 and 2008 models, exhibited transmission glitches, with symptoms like slippage and fluid leaks from compromised cooling lines, leading to an average replacement cost of about $2,035. Additionally, a significant recall (ID 15V606000 / 15S28) targeted Mariners with remanufactured CD4E transmissions from mid-2015, addressing a loose shift lever bolt risk. Ford's resolution involved either tightening the bolt or replacing the shift lever assembly. Other highlighted issues from Technical Service Bulletins encompassed engine stalling, missing gears, and common transmission ailments like leaks, unresponsiveness, and unusual sounds. While Mariners might achieve up to 180,000 miles without transmission issues, neglecting maintenance or unresolved design flaws could introduce complications. The go-to method for pinpointing these problems involves diagnostic tools, and based on detected codes, interventions might involve specific part replacements or even entire transmission overhauls.
