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 PROBLEM. THE SECOND TIME WAS ALSO AROUND 40 MPH AND PUSHING THE BRAKES AS HARD AS POSSIBLE 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 AGAIN 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. *KB

DP22005 · Pedestrian Alert Sounds
Opened Jan 27, 2023 · Closed Aug 7, 2023
Status: closed (inferred from source dates) · Electrical System:propulsion System
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.
DP15001 · Loss Of Power Steering While Driving
Opened Apr 1, 2015 · Closed Jun 14, 2018
Status: closed (inferred from source dates) · Steering:electric Power Assist System
On May 27, 2014, amended June 2, 2014, Ford Motor Company (Ford) submitted a Defect Information Report (DIR) to NHTSA describing a safety defect that may result in a sudden loss of power steering assist while driving in approximately 746,067 model year (MY) 2008 through 2011 Ford Escape vehicles equipped with electric power assisted steering (NHTSA 14V-284, Ford 14S05). Ford's DIR described the defect condition as a poor signal to noise ratio [SNR] in the torque sensor within the Electric Power Assisted Steering (EPAS) system [which] does not allow the PSCM to determine the driver's steering input. When the system detects this fault condition, it transitions the EPAS system to the fail-safe/manual steering mode.Ford's DIR indicates that loss of power steering assist while driving would require higher steering effort at lower vehicle speeds, which may result in an increased risk of a crash.Ford's remedy instructs dealers to check the Power Steering Control Module (PSCM) for Diagnostic Trouble Codes (DTCs) to determine the proper repair procedure. If no DTCs are present, dealers are to update the PSCM and instrument cluster module software. The updated PSCM software changes the torque sensor fault strategy so that the SNR condition does not result in a loss of power steering assist while driving.In addition, audible and visual warnings are provided for torque sensor faults.If DTCs indicating faults in the torque sensor, PSCM or Power Steering Motor (motor) are present in the initial recall inspection, the dealer performs the following repairs: 1) replaces the torque sensor for torque sensor faults (DTC B2278); or 2) replaces the steering column for faults related to the PSCM (DTC B1342) or motor (DTC B2277).Continued in attachment pages
