2008 Mercury Mariner Brakes Problems

The contact owns a 2008 Mercury Mariner. The contact stated that while driving at 30 MPH, he had to hard brake, however, afterward while depressing the brake pedal, the brake pedal traveled to the floorboard. The vehicle was taken to the dealer where the failure was diagnosed as a hydraulic control unit (HCU) failure. The contact was informed that the HCU needed to be replaced. The contact stated that the vehicle was not repaired as the parts were on backorder. The contact stated that he discovered NHTSA Campaign Number: 19V904000 (Service Brakes, Hydraulic) however, the VIN nor the Year/Make/Model was not included in the recall. The manufacturer was notified of the failure and informed that contact to call the NHTSA Hotline to file a complaint. The approximate failure mileage was 89,000.

I see a recall NHTSA campaign #19V904000 ,MFG campaign #19S54 Also a NHTSA recall#150546 How am I going to drive with brakes on the floor My vehicle is a 2008 Mercury Mariner Thanks in advance

2008 MERCURY MARINER. THE VEHICLE SPORADICALLY AND INTERMITTENTLY BRAKES WHILE DRIVING AND ACCELERATING. THIS WAS A REPORTED ISSUE MANY YEARS AGO ON THESE CARS BUT FORD NEVER ISSUED A RECALL EVEN THOUGH THERE ARE A NUMBER OF BRAKING ISSUES WITH THIS VEHICLE. THIS MAKES THE VEHICLE EXTREMELY DANGEROUS TO DRIVE IF YOUR BRAKES WITHOUT WARNING LOCK UP. I CONTACTED THE LOCAL DEALER AND FORD CORPORATE AND THEY WERE OF NO HELP. I ALSO FILED AN INCIDENT REPORT WITH FORD CORPORATE #CAS31601808.

DRIVING, COMING TO A STOPLIGHT, THE BRAKES SUDDENLY FAILED, THE BRAKE PEDAL WENT ALL THE WAY TO THE FLOOR. PUMPING I WAS ABLE TO GET JUST ENOUGH BRAKES TO STOP BEFORE COLLIDING WITH THE CAR IN FRONT OF US. THE SERVICE ABS AND EMERGENCY BRAKE SERVICE WARNING LIGHTS CAME ON AFTER THE NEAR COLLISION. I TOOK THE CAR TO A FORD DEALERSHIP AND WAS TOLD THE HCU UNIT HAD FAILED. THIS IS A $4,000 PART THAT WE HAD ALREADY REPLACED AT 76,000 MILES,. THE NEW PART FAILED AGAIN WITHOUT WARNING ONLY 22,000 MILES LATER.

THE ABS HYDROLIC CONTROL UNIT HAS MALFUNCTIONED RESULTING IN FAULTY BRAKES AND DANGEROUS DRIVING CONDITIONS. I HAVE TO PUT THE BRAKE PEDAL TO THE GROUND TO GET ANY TYPE OF BRAKING TO BE DONE. THIS TAKES EXTRA SECONDS THAT COULD RESULT IN AN ACCIDENT IF I HAD TO SUDDENLY BRAKE. THIS SEEMS TO BE A COMMON PROBLEM AND MANY MARINERS AND ESCAPES HAVE IDENTICAL PROBLEMS. I WOULD LIKE MY VIN TO BE ADDED TO THE RECALL LIST TO HAVE THIS PROBLEM FIXED.

MY VEHICLE HAD DIFFICULTY IN STOPPING, NEEDING THE PEDAL TO BE PRESSED ALMOST TO THE FLOOR BEFORE IT STOPPED. I CHANGED THE MASTER CYLINDER IN HOPES THAT IT WOULD FIX THE PROBLEM BUT IT DIDN'T. THE BRAKES PERIODICALLY WOULD WORK PROPERLY, BUT ONCE AGAIN THE PROBLEM WOULD RETURN. I STOPPED BY THE FORD DEALERSHIP AND THEY ADVISED ME THAT THE 2008 MERCURY MILAN WAS RECALLED FOR THIS DEFECT, HOWEVER, MY 2008 MARINER WASN'T ON THE LIST TO BE RECALLED. THE DEALERSHIP ADDED THAT THE PARTS FOR THE REPAIR WAS ON BACK ORDER. I STILL DRIVE THE CAR BUT CAUTIOUS WHENEVER I NEED TO BRAKE.

I STARTED HAVING PROBLEMS WITH MY BRAKES. WHEN I STEP ON THE BRAKE THE PEDAL WOULD GO ALMOST ALL THE WAY TO THE FLOOR. I WOULD REACT BY PUMPING THE BRAKE WHICH WOULD MAKE THEM WORK. I DIDN'T DRIVE WITH THE BRAKES DOING THAT VERY LONG BECAUSE I TOOK THE CAR TO A REPAIR SHOP AND I SPENT 450 DOLLARS ON BRAKE WORK WITH BEING TOLD THAT THE PROBLEM WAS WITH THE ABS SYSTEM AND THE DISABLED THE ABS SYSTEM SO THAT IT DIDN'T INTERFERE WITH STOPPING THE CAR. THERE HAVE BEEN RECALLS ON OTHER FORD PRODUCTS BECAUSE OF ABS PROBLEMS. THE PROBLEM OCCURRED WHILE I WAS DRIVING EVERY TIME I WANTED TO STOP AND WHEN I STOPPED FOR A LIGHT I FELT LIKE THE BRAKES MIGHT QUIT WORKING AND THE CAR COULD ENTER THE INTERSECTION. *TR

BRAKES SUDDENLY STOPPED WORKING WHILE MY 17 YEAR OLD DAUGHTER WAS DRIVING. A MESSAGE APPEARS 'REGEN BRAKES DISABLED, CHECK BRAKE SYSTEM'. WENT TO DEALERSHIP AND WAS TOLD HCU AND MASTER CYLINDER NEEDS TO BE REPLACED $4000 REPAIR. NOT ACCEPTABLE SEEING SO MANY COMPLAINTS OF THIS ISSUE THAT FORD HAS NOT YET ISSUED A RECALL. *TR

MY 17 YEAR OLD DAUGHTER CAME HOME SAYING A MESSAGE WAS ON HER DASH ABOUT HER BRAKES IN OUR 2008 MERCURY MARINER HYBRID. I WAS ABOUT TO LEAVE SO I DECIDED TO TAKE HER CAR, AS SOON AS I PULLED OUT OF THE DRIVEWAY AND STARTED DOWN THE HILL WE LIVE ON, I NOTICED THE BRAKES DIDN'T FEEL RIGHT, I PRESSED ALL THE WAY DOWN TO GET THE CAR TO SLOWLY COME TO A STOP, AS I DID THIS, I NOTICED A WARNING SOUND AND THE MESSAGE ON THE SCREEN SAID CHECK BRAKE SYSTEM, REGEN BRAKES DISABLED. I IMMEDIATELY TURNED THE CAR AROUND AND WENT HOME, WHEN TRYING TO STOP IN OUR DRIVEWAY, AGAIN THE BRAKES WERE NOT WORKING PROPERLY CAUSING US TO ALMOST HIT THE OTHER CAR IN THE DRIVEWAY. THIS IS EXTREMELY CONCERNING AS THIS CAR IS OUR 17 YEAR OLD DAUGHTERS CAR. ONCE YOU GET THE CAR TO STOP, IF THE CAR IS POWERED OFF FOR A FEW MINUTES AND BACK ON THE BRAKES WORK AGAIN. THIS IS A SAFETY ISSUE AND SEEMS TO BE A COMMON PROBLEM. THIS HAPPENED YESTERDAY 5/16/2020, THE CAR HAS 120K MILES.

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.

ABS AND REGEN BRAKES DISABLED WARNING LIGHTS WENT ON WHEN STARTING CAR FROM PARKED POSITION; HAVE BEEN ADVISED BY FORD DEALER AND ON LINE REPORTS BY CAR OWNERS THAT BRAKES CAN FAIL AND WE SHOULD NOT DRIVE THE CAR. REPLACING REGEN BRAKE SYSTEM MORE THAN 6K ; THIS IS A SAFETY PROBLEM REQUIRING MANUFACTURER RECALL;

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.

BRAKE SYSTEM FAILURE, ABS FAILURE. HALF OR MORE OF BRAKING POWER DIMINISHES. WHILE GOING DOWN THE ROAD, VEHICLES TRIES STOPPING ITSELF, CREATING A FRONT END WOBBLE. WHEN HAVING TO USE THE BRAKES, TIRES SKID. CANNOT STOP VEHICLE QUICKLY, VERY DANGEROUS. CONSTANT BRAKE SMELL. BRAKE PADS WEAR OR DISINTEGRATE WITHIN 3 MONTHS. PROBLEM WILL NOT GO AWAY WAS INTERMITTENT AT FIRST, BUT NOW CONSTANT. FORD DEALERSHIP REPORTS PART IS $6200 DOLLARS. THE VEHICLE IS NOT WORTH THAT.

I lost all braking ability and the pedal goes to the floor. This is a Mercury Mariner Hybrid and Ford Escape Hybrid issue, it doesn't affect the non-hybrid models. Ford knows about this as there are hundreds and hundreds of complaints online about it and it's a $5000+ fix. I have not been able to drive my Mariner Hybrid since 2018.

HCU (HYDRAULIC CONTROL UNIT) FAILURE MEANING MY HYBRID VEHICLE CAN'T BRAKE WHETHER IN HYBRID MODE OR NORMAL MODE AND IT'S OVER A $5000 REPAIR. MY MARINER HAS BEEN SITTING IN MY DRIVEWAY FOR CLOSE TO 2 YEARS NOW, UNUSED, BECAUSE OF THIS KNOWN ISSUE. *TR

TOOK TO DEALER FOR BRAKE PROBLEMS. POOR AND UNPREDICTABLE STOPPING, AFTER OVER $ 500 REPAIRS TO BRAKES. WORKED OK FOR A WEEK NOW WORST THAN THEY WERE BEFORE REPAIRS.BRAKES CANNOT BE TRUSTED.

TL* THE CONTACT OWNS A 2008 MERCURY MARINER. THE CONTACT STATED WHILE DRIVING 60 MPH AND DEPRESSING THE BRAKE PEDAL, THE BRAKE PEDAL REQUIRED ADDITIONAL BRAKE TRAVEL TIME TO STOP THE VEHICLE. THE CONTACT STATED NO WARNING LIGHT WAS ILLUMINATED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED WITH NEEDING THE BRAKE MASTER CYLINDER TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. UPON INVESTIGATION, THE CONTACT ASSOCIATED THE FAILURE WITH NHTSA CAMPAIGN NUMBER: 19V904000 (SERVICE BRAKES, HYDRAULIC) HOWEVER THE VIN WAS NOT INCLUDED. THE MANUFACTURER WAS NOT INFORMED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 100,000.

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.
