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

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
