Service Brakes problem #1

The abs system turn off, took to shop they could not fine trouble it had reset. Today same thing abs turn off. Will take it in if it does not reset. Both times that it turn off car was parked and I was just starting it to leave. .

Service Brakes problem #2

While driving down the road, all of the warning lights on the dash board came on and then the breaks failed. We were able to get to safety after going off the road. When taken into the Ford motor company repair shop they reset the codes and said everything was fine, no parts to repair. Less than 50 miles later, the same thing happened again injuring 3! this time it's the abs module. After calling the Ford motor company, they refuse to admit there is any problem and no reason for a recall. We were given the NHTSA information to make a complaint and if eventually NHTSA informs Ford that they must do a recall we can be given a refund for our money spent on this repair. Our question is what happens when someone dies? does it take that before someone is going to do something about the known hybrid breaking problems? the manger at the Ford motor company customer service doesn't think it's an issue worth looking into only to say that a vehicle with high mileage should be taken care of and repaired by the owners. Not that Ford is responsible for faulty parts! please NHTSA do something about the hybrid breaking system before multiple people continue to be injured or are killed!.

Service Brakes problem #3

This vehicle has lost brakes 3 times. My now 17 year old daughter is the driver! the first time the brake pedal went to the floor and pumping it would not help. Putting the car in neutral and using the emergency brake was the only way to stop the car. A non-Ford car technician told us it was a possible brake booster issue and the best thing to do would be for it to happen again and bring it to Ford for the codes to be read. I drove the car for over a week and it would not repeat the probelm. The second time was also around 40 mph and pushing the brakes as hard as posible would only slightly stop the car and it would keep jumping forward. My daughter had to stop with the e-brake. I took it to Ford for diagnosis and repair. Ford replaced the vacuum pump/hose assembly. Then 2 days later, she lost brakes again. Had to use e-brake to stop in busy traffic. The southeast region Ford technician came to diagnosis this car. After 9 days at the shop the brake booster assembly was replaced. We have been told again that this should take care of the problem. Fyi ( each time the car lost brakes, by turning off the car and back on agian it would regain them). I am now driving this car to determine if the issue is in fact taken care of. This has been a very scary situation - especially since my daughter is the driver of this vehicle. When reading automobile blogs it appears brakes are an issue not only with the Mariner Hybrid, but the escape hybrid as well. I would like this investigated.

Service Brakes problem #4

Mercury Mariner Hybrid 2009 had it for 18 months and August 3, 2010 upon an approach to a stop light engaging the brakes I heard an audible warning sound and looked at my console to see the warning to check brakes, at that moment my brake pedal went soft and to the floor, I had to apply the emergency brake to stop the mariner to avoid hitting the vehicle in front of me. I parked ASAP in a gas station leaving the mariner and calling for a ride back to my office to pick up another vehicle to get home and the next morning contacted my dealership instructing me to contact Ford to get it towed to them, later that day I get a call from the service department telling me that it was not covered under warranty because I had 40,000 mile on a 18 month vehicle and the repair cost is $1,700. 00. My wife and self could have been injured or worse. I will be willing to cooperate to any extent to help escalate this concern as a safety recall issue.
