ABS BRAKE LIGHT WARNING CAME ON. BRAKES PRETTY MUCH STOPPED WORKING WITHOUT ANY PRIOR WARNING TO THE LIGHTS. HAD TO DEPRESS THE PEDAL ALL THE WAY TO GET BRAKES. VERY UNSAFE. NOW THE BRAKE IS STUCK ON AND THE CAR DOESN'T MOVE. HAVE TALKED TO AND READ ABOUT SEVERAL PEOPLE THAT HAD THE SAME ISSUE. WHY HASN'T THERE BEEN A RECALL YET?

IN STOP AND GO CITY TRAFFIC GOING ABOUT 1 MILE AN HOUR I BRAKED BUT MY MARINER DIDN'T AND I SLOWLY REAR ENDED ANOTHER VEHICLE. MY ABS SENSOR WENT ON THEN OFF EVENTUALLY AN ABS REGEN LIGHT CAME ON AND I HAD NO BRAKES SO I DROVE ,VERY CAREFULLY, 83 MILES TO MY FORD DEALER ( WITH NO BRAKES) TO FIND OUT THAT I NEEDED A COMPLETE REPLACEMENT OF MY ABS HYBRID BRAKING MODULE. $3900! MY MECHANIC AND I CALLED TWO DIFFERENT JUNK YARDS WHERE WE RECEIVED REPLACEMENTS AND THEY WERE INSTALLED BUT WHEN BROUGHT BACK TO THE FORD DEALER THE UNITS WOULDN'T TAKE THE COMPUTER CODE AND THE (USED) SYSTEMS FAILED. $3900 IS A LOT OF MONEY FOR A VEHICLE, WITH 158,000 MILES ON IT, THAT I BOUGHT USED FOR UNDER $5000. THAT SAID IS THERE ANYWAY THAT THIS ABS HYBRID BRAKE MODULE SHOULD HAVE BEEN ON A RECALL LIST. ARE OTHERS HAVING SIMILAR ISSUES? IS THIS WHY THEY QUIT MAKING HYBRIDS AT THIS TIME? I DON'T KNOW BUT I'M THINKING THIS IS A RECALL ISSUE AT THAT PRICE.

"TAKATA RECALL" WHEN I WAS LEAVING A STORE YESTERDAY I NOTICED THAT MY ABS, BRAKE LIGHT CAME ON ALONG WITH A DESCRIPTION INDICATING MY CHECK BRAKE SYSTEM. I NEVER NOTICED AN ISSUE WITH MY BREAKS PRIOR TO THESE SIGNALS COMING ON AND MY FIANC'S CAR HAD BEEN FUNCTIONING WELL FOR THE LAST FOUR YEARS. I NORMALLY DRIVE THE SUV SO WHEN I NOTICED IT SAID THAT I MADE SURE THE BREAKS WERE WORKING WHEN I STARTED TO MOVE. I DID NOTICE THAT THE BREAKS REQUIRED MORE OF A FIRM PUSH WHEN I WAS NEEDING TO COME TO A SPOT. I DIDN'T HAVE ANY ACCIDENTS OR CAUSED ME TO RUN ANY STOP LIGHTS OR STOP SIGNS. HOWEVER, AFTER DOING MY OWN RESEARCH I DID FIND OUT THAT THIS IS A PROBLEM FOR THE 2008 MERCURY MARINERS AND FROM SOME OF THE WARNINGS I HAVE READ STATED THE BREAKS ENDED UP FAILING AFTER THIS ALL ACCRUED AND ABOUT GOT THEM INTO ACCIDENTS. WITH THE NHTSA ALREADY INVESTIGATING THE '2006-2012 FUSION AND LINCOLN MKZ AND THE 2006-2011 MERCURY MILAN' MODELS WITH THE SAME ISSUES, IT SEEMS THE ISSUE IS BIGGER THAN JUST THE MERCURY MARINER.

HEADING WEST ON THE INTERSTATE I TOOK THE OFF RAMP AND CAME TO A STOP. AS I WAS STOPPING A TONE RANG OUT, THE ABS LIGHT, AND BRAKE WARNING LIGHT CAME ON. THE BRAKES DIDN'T FEEL AS STIFF AS THEY SHOULD HAVE BUT I DID COME TO A STOP AS I WASN'T TRAVELING VERY FAST WHILE APPROACHING THE STOP SIGN. I TURNED LEFT AND PROCEEDED OVER THE OVERPASS TOWARDS A SIDE ROAD WHEN A CAR THAT HAD COME UP THE OFF RAMP FROM THE EASTBOUND LANE ROLLED THE STOP SIGN AND STOPPED WITH THE NOSE OF THEIR VEHICLE IN MY LANE. I NEARLY PUT THE BRAKE PEDAL THROUGH THE FLOOR AND HAD LITTLE TO NO BRAKES TO STOP ME. I AND MADE A SPLIT SECOND DECISION TO SWERVE AROUND THE CAR, DRIVING IN THE ONCOMING LANE AS I WAS ABLE VERIFY THERE WAS NO ONCOMING TRAFFIC. ONCE I PULLED OVER ON A SIDE ROAD I NOTICED THE DISPLAY IN THE DASH READ "REGEN BRAKE DISABLED" I DROVE SLOWLY TO A SMALL CAR SALES LOT WITH AN AUTO SHOP AND THEY RESEARCHED FOR A FEW MINUTES AND TOLD ME I WOULD HAVE TO TAKE IT TO A DEALER TO REPLACE A HYDRAULIC PUMP. THEY WERE ABLE TO FIX THE ISSUE BY DISCONNECTING THE BATTERY FOR A BIT BUT SAID MORE THAN LIKELY THE FIX WOULDN'T LAST. NEXT STOP IS THE FORD DEALER BUT FROM WHAT I'VE READ TONIGHT, MANY OTHER USERS HAVE EXPERIENCED THE SAME ISSUE AND HAVE BEEN QUOTED OVER HALF THE BOOK VALUE OF THE VEHICLE TO FIX THE ISSUE. I WAS GLAD NOT TO SLAM INTO THE PASSENGER DOOR OF THE LADY WHO PULLED OUT IN FRONT OF ME, I WAS GLAD I HAD A CLEAR LANE TO AVOID HER WITHOUT HAVING A HEAD-ON COLLISION BUT I CAN SEE WHERE THIS ISSUE COULD HAPPEN AT THE WRONG TIME AND PLACE AND CAUSE HARM OR LOSS OF LIFE FOR THOSE INVOLVED. BECAUSE I HAD LITTLE TO NO BRAKES WITH THE PEDAL PUSHED ALL THE WAY TO THE FLOOR

I PUT MY 2006 MERCURY MARINER HYBRID INTO REVERSE TO BACK OUT OF MY DRIVE WAY. I APPLIED A LITTLE GAS AND BEGAN ROLLING DOWN THE INCLINE TOWARDS THE STREET. AS I APPROACHED THE STREET I PUT ON MY BRAKES, BUT NOTHING HAPPENED AND I FAILED TO SLOW DOWN. A CODE DISPLAYED ON MY DASH READING, "REGEN BRAKES" THE LAST WORD WAS EITHER FAILURE OR DISABLED. I CAN'T REMEMBER BECAUSE I WAS IN A PANIC ABOUT MY BRAKES NOT WORKING WITH MY FAMILY IN THE CAR. I APPLIED THE BRAKES AGAIN. THE BRAKE PEDAL WAS HARD TO PUSH AND THOUGH I TRIED WITH ALL MY STRENGTH, IT DID NOT STOP THE CAR. MY HUSBAND THEN PULLED THE PARKING BRAKE FROM THE PASSENGER SEAT. I TURNED THE CAR OFF TO COLLECT MYSELF, HOPING THE FAILURE WAS SOME WEIRD FLUKE, AND TURNED THE CAR BACK ON. IT IMMEDIATELY DID THE SAME FAILURE. AT THIS POINT, I PUT THE CAR IN PARK AND MY HUSBAND OFFERED TO DRIVE IT AROUND THE BLOCK AND BACK INTO THE GARAGE. IT NEVER SHOWED ANOTHER CODE AFTERWARDS. WE LEFT THE CAR FOR A FEW HOURS AND THEN CAUTIOUSLY DROVE IT TO THE GAS STATION. NO MORE CODES OR ISSUES. HOWEVER, WE NO LONGER FEEL WE CAN SAFELY DRIVE THE CAR AS WE HAVE NO IDEA WHEN THE BRAKES COULD GO OUT AGAIN. NEXT TIME WE MAY NOT BE SO FORTUNATE AS TO BE ON A RESIDENTIAL STREET WITH NO OTHER TRAFFIC.

HCU MODULE FAILURE AT 60,000 MILES. THIS FAILURE IS MENTIONED INTSB 05-8-5 & IN NHTSA ID# 10017553 THIS SEEMS TO BE A RECURRING PROBLEM IN MANY FORD ESCAPE/ MERCURY MARINER HYBRIDS GOING BACK TO 2005. MY DEALER ESTIMATED THE COST TO BE ALMOST $6000. THIS IS VERY DISTURBING, ESPECIALLY SINCE THIS VEHICLE HAS BEEN WELL MAINTAINED SINCE PURCHASED IN 2009. IS FORD GOING INVESTIGATE THIS PROBLEM? CAN YOU DO ANYTHING TO HELP WITH THE FINANCIAL BURDEN PLACED ON AN OWNER OF ONE OF YOUR VEHICLES? WE HAVE PURCHASED A NUMBER OF FORD PRODUCTS OVER THE YEARS & FEEL THAT CUSTOMER LOYALTY SHOULD BE CONSIDERED. I HAVE LOST FAITH IN FORD SINCE THIS HAS OCCURRED. I HAVE DECIDED TO NOTIFY YOU OF THIS SITUATION SINCE THIS REPAIR COST IS OUT OF THE QUESTION. THANK YOU FOR YOUR CONSIDERATION IN THIS MATTER.

ABS WARNING LIGHT COMES ON AND CHECK BRAKE SYSTEM MESSAGE COMES ON AT ANYTIME WHILE DRIVING ON SITTING STILL. LOSE BRAKING POWER, CAUSING DRIVER TO PUSH BRAKE VERY HARD TO STOP AND BRAKE PEDAL SOMETIMES GOES TO THE FLOOR AND YOU HAVE TO USE EMERGENCY BRAKE TO STOP. DEALER COULDN'T LOOK AT THE CAR FOR THREE WEEKS SAID ITS OKAY TO DRIVE IN "MANUAL MODE", HOWEVER MANUAL MODE ONLY USES REAR BRAKES AND WILL TAKE VEHICLE A LONG DISTANCE TO STOP IN RAINY CONDITIONS.(I WENT THROUGH A BUSY INTERSECTION IN THE RAIN AND ALMOST HAD AN ACCIDENT SO LEFT IT AT THE DEALER). DEALER HAD VEHICLE FOR ALMOST SIX WEEKS, REPLACED THE ABS HUC TWICE, FINALLY CALLED FORD. FORD ADVISED TO REPLACE ALL BRAKE HOSES "DUE TO RESTRICTIONS". DEALERS ARE TELLING OWNERS THEY HAVE TO REPLACE ABS HCU AND PART ALONE COST $4700.00. HOWEVER, FORD KNOWS OF THE PROBLEM AND IS NOT PUTTING OUT A BULLETIN OR RECALL, UNTIL SOMEONE GETS KILLED. OWNERS ARE TRADING THE UNSAFE CAR BECAUSE THE DEALER IS MISDIAGNOSING THE REAL PROBLEM WHICH COST APPROXIMATELY $300.00

AFTER PRESSING THE BRAKE PEDDLE, THE ABS LIGHT AND RED BRAKE LIGHT COME ON AND THE REGENERATIVE BRAKING AND POWER BRAKES FAIL. IT SEEMS TO HAPPEN ONLY WHEN THE OUTDOOR TEMPERATURE IS OVER 90 DEGREES. ONCE IT HAPPENS, BRAKING REQUIRES A HARD PUSH OF THE BRAKE PEDDLE TO THE FLOOR AND STOPPING TAKES LONGER. IT IS INDEED DANGEROUS. MY RESEARCH SHOWS THAT THIS IS A COMMON AND DANGEROUS PROBLEM. THANKS FOR YOUR TIME, [XXX] *TT
