Brake Light On problems of the 2008 Mercury Mariner

Brakes are intermittent, abs light will come on along with red brake light and hybrid regen brakes disabled. Sometimes car stops sometimes car does not stop. I have looked into it and several people have reported failure. I do not understand how such a well documented oe failure can go for so long without rectification.

The brake light came on and indicated "regen brakes disabled". I braked when I came to a traffic light and ended up skidding into the middle of an intersection. The local Ford dealer advised to replace the hcu for $5000. The unit has 55k miles on it. This has continued to happen for the last 2 years, mostly in the summer when it is hot and humid, although just today it happened again (it was 35 degrees all day). I couldn't stop in time and ran off the road onto the median. Some online research has indicated the problem is not with the hcu, but the sensors (replacing the hcu reestablishes a good connection with the sensors). , but the Ford dealer knows nothing about this fix because it's much cheaper. So, I have no choice but to continue to drive this train wreck and hope I'm not in a serious accident.

Takata recall my abs light and brake light comes on and if I drive it with these lights on I smell my break pads burning. I took it to Ford and they said it was the internal failure of the hydraulic control unit and it would cost me upwards of $5,885. 00 to replace and repair the problem. I have searching the internet and there are several other people with the same problem with this vehicle and Ford escapes. (which is basically the same vehicle. If there are this many complaints maybe its worth looking into on dots part. It is a safety issue for sure considering my brakes go to the floor when the abs and brake lights are on. I can turn my SUV off and remove the key and then put the key back in and start it again until the lights go off and I don't have an issue. But when I first get in the vehicle and start it the lights do in fact come on. Please help all consumers with this dangerous situation that should have been recalled already on Ford/Mercury's hydraulic control unit.

While driving on the highway check brake system message and brake light comes on vehicle braking becomes very hard to stop. After stopping vehicle and turning vehicle off and on several times brake warning light goes off and vehicle drives normally for a few days than problem comes back. While at a light one day brake warning light came on drove for approximately 1 mile and no brakes at all was able to turn in to a parking lot and apply the emergency brakes to stop. Left vehicle over night the next day turned vehicle on and off several time and brakes began to work. Made appointment with dealer who advised it will be three weeks to get it in. After three weeks to take vehicle in a week later was advised abs hcu was probably bad. Cost for new abs hcu module $4700 for the part alone. Picked up vehicle without having it fixed and drove locally for a few weeks with brake in "manual mode" until I tried to stop for a yellow light in the rain and slid through the intersection since only the back brakes works in manual mode. Later ordered a refurbished abs hcu module cost $1400. 00, the Ford dealer is the only one who can install unit since the module has to be programed to the vehicle software. Took two weeks to get an appointment dealer had vehicle for another six weeks trying to program and bleed brake system. Dealer finally installed the other abs hcu unit that was sent to me when I advised the refurbishing company that the dealer was having issues with the first one. Dealer advised that they installed the replacement abs hcu and replaced the brake lines, and the brakes started to work labor cost $1900. 00. I'm glad to be here to report this safety issue the next person would probably not be so lucky.

Abs light along with service brake light came on with no warning resulting in near complete brake loss and nearly striking a person crossing the street.
