2 Radiator problem of the 2006 Mercury Mountaineer

Failure Date: 11/10/2015

My 2006 Mercury Mountaineer was leaking coolant due to a crack in the radiator. After searching online forums, I have learned that has been a long standing issue with many of this vehicles owners. Unfortunately for owners, Ford issued a tbs in 2009 just in time for most of the affected vehicles' warranties to expire. Some owners are on their 3rd or more radiator replacement, I am only on my first. I petition that Ford recalls this issue before myself and others have to repeatedly pay for this clear design problem with their hard owned money. This problem also poses safety risk to the passengers operating these vehicles and to any animals attracted to the sweet smell of the coolant from affected vehicles whose owners who may not yet know this issue or cannot afford to fix it.

9 Radiator problem of the 2007 Mercury Mountaineer

Failure Date: 05/01/2012

I was driving on the highway and noticed that my steering was not working well. My engine was overheating and eventually shut off. I had to pull over on the side of the highway. When I got someone to look at the car, we realized it had no coolant. We filled up the coolant and everything seemed fine. About a month later I noticed that the engine was making the same noise as it had before as if it were working too hard. I checked the coolant and it was completely empty again. I have a friend who also owns the mm and had the same problem. The repair and cost of a new radiator was 1500. Ford/merucy needs to do a recall on this product and get it taken care of. I just purchased this car in January and should not have to be spending so much money on a repair.

10 Radiator problem of the 2006 Mercury Mountaineer

Failure Date: 11/17/2011

The radiator coolant system is junk. Busted seals and hoses all the time. Iam beginning to think this car is a lemon. I replaced my radiator less than 1 year ago, had the part replaced with the factory part Ford supplies and once again I have a busted seal and have to replace the radiator again. When are they going to recall this part? seriously I've done my research and the radiators on these vehicles busting isnt an isolated incident. Is Ford going to pay $400. 00 dollars every 6 or so months to replace my radiator. I wish someone would file a class action law suit or something.

New showroom 2002 Mercury Mountaineer. The engine in this vehicle malfunctioned twice without warning; no overheating, no dashboard light indicators either time. July 2004/odometer reading 92213, the mechanics at the freeway Lincoln Mercury were baffled. They advised me that all the fluids were in the vehicle. Later (one week) they found a "hole" in the radiator. I was told I had a new engine, with a new warranty. 2nd time was June 06, odometer 166199,(new engine 73986) no warning, no dashboard lights, no overheating. Per a different certified mechanic not only was the engine not new but it had severe corrosion in it and showed signs of multiple overheating conditions. They told me of an "all technical service bulletin" dated 1/21/02 for my vehicle's engine regarding the "engine head gasket"---"some engine assemblies with aluminum cylinder heads repaired in-vehicle have been found to leak coolant and/or oil from the cylinder head gasket area due to particle contamination or scratches and dents to block mating surfaces. " action: refer to the following service information for recommended gasket sealing surface preparation procedures. If the engine diagnosis points to a faulty head gasket (leaks oil, leaks coolant, oil or coolant contamination, or air in coolant), thorough cleaning procedures are necessary for a successful head gasket repair. Diagnosis and post- repair confirmation can be done successfully utilizing leak detection methods such as a black light dye process. Service procedure:to sum up, a successful leak repair depends on:accurate diagnosis of the leak using Ford-recommended test equipment and procedures . Surface preparation and gasket installation using the approved tools, cleaners, and methods. Exercising care and cleanliness during disassembly/assembly of components use of genuine Ford oem replacement parts<use of a Ford remanufacturer.
