I have a 2008 Mercury Mariner hybrid. Sometimes when I apply the brakes with medium pressure the left rear of the vehicle will vibrate so hard it rattles the trim in the storage area. It is as though the ABS is operating only on that wheel but much more pronounced than when the ABS normally actuates. There is no consistency as to when or where this condition occurs. It will not happen for days, then will occur every time I brake for a time period (no particular length). Consumer stated he traded in on a 3 year old vehicle. Consumer stated he has no more information regarding the vehicle left all of the records he had in the vehicle when he traded it in. Updated 6/8/18

Failure of ABS brakes on 2008 Mercury Mariner hybrid. This has happened to my car twice. Summer of 2009 and the summer of 2010. Both times I have had to replace the master brake cylinder. Symptoms include inconsistent braking response and loss of brake fluid. Driver experiences overly sharp braking and a "grabbing" sensation as well as very soft braking and "coasting" sensation almost as if there are no brakes or very little braking. It is very hard to drive safely in this condition. Both times, repair included replacing the master cylinder with a $1500 bill. This resulted in $3000 in repair costs to avoid continuing to drive the vehicle in an unsafe condition. The master brake cylinder should not have failed once on a 2008 car much less twice and the dealership has as much told me they feel this may be a system design flaw that needs correcting through recall.
