Passenger side rear inner fender well rusted completely through above the rear shock causing the shock to potentially break through and drop the whole suspension and cause and accident or flip over if it broke through during a turn. The rest of the vehicle hardly has any rust on it. The mariner shares the same inner sheet metal as the ford escape and there have been many complaints of this happening to escapes. My vehicle was studied at a ford investigation about 4 years ago for this problem. I was told they were working on a solution and nothing ever happened. The employee told me that the undercoating they used of these years of escape/mariners was faulty and broke down prematurely causing the inner fender exposed to the elements. This is also happening on the driver's side where the undercoating is start to break down. This is not a case of misuse by the owner but an actual design flaw and a big safety issue as this could cause a lot of harm. Luckily I heard the loud knocking from the rear end and stopped driving it.

The brake system's hydraulic control unit ("hcu"). On several occasions while driving, the brake pedal will travel to the floor while trying to brake resulting in no braking action (ie., vehicle not slowing). This might happen for one or two pedal depressions before there is any slowing of the vehicle. This problem has placed me in situations where I have to take evasive action to not hit a vehicle in front of me, or traveling into a controlled (with stop signs) intersection. Below there is a space to specify 'when did this happen.' I am inputting the most recent date of this problem, but it has happened at least ten times before this.

The power steering went out in my mother's 2007 mariner hybrid with 72,000 miles due to failure of the power steering control module. After searching online forums, I found this to be a rather common issue on the 05-07 mariner and escape hybrids. The repair will cost just under a thousand dollars once you locate the part. After having it diagnosed at my ford dealer, I contacted ford customer care to see if they could resolve the issue, and they acted like it was something they were unaware of even though it does not take much searching to see it's a common problem. Also it's a safety issue. The same part was recalled on the 08-11 escape and mariner hybrids, and the recall should have included the 05-07 as well.
