2009 Mercury Mariner brakes complaints

Have had multiple brake failures including an accident that my daughter was involved in as a result of brake failure. The brakes will work fine for a short period of time and then out of nowhere you step on the brake and there's just a soft pedal for about 3/4 of the was before you get a very soft brake. Into this for thousands and now ford says a hydraulic brake sensor is the problem for between $2100-2400. Heard that it was fixed every time I've picked it up. Dangerous!!! My daughter or someone else could have been killed.

While I was driving on hwy doing 75mph my mercury mariner 2009 it suddenly loss power and (while engine was running) I could not accelerate. "tool" light came on. I could not do anything to regain speed (accelerator was disable) and the only fix was to shut down the engine and re-start. Vehicle will start and work normally I took to the mechanics the next day he said that no codes came up.

Coming to red light one car in front of me. I pushed down on brake petal and it was hard to push down. Engine revved up to over 5 RPM's and car wouldn't stop finally I put car in neutral and engine went back to idle position. Almost rear ended car in front of me. Took mariner to dealer who wasn't very helpful because he never heard of this before & wanted to know if I wanted to leave mariner there. Also ask if I had my foot on the gas petal instead of the brake. Dealer was unable to verify concern so they replaced canister purge valve. Have also had transmission problems with this mariner that I believe still exist. Filled out surveys and was told manager would call but no one ever contacted me. Very unprofessional dealer.
