THE POWER TORQUE SENSOR FOR THE POWER STEERING WAS ALREADY RECALLED AND HAD THE SYSTEM UPDATED BEFORE I GOT THE CAR IN 2014. THE CARS STEERING WHEEL STARTS SHAKING A LITTLE THEN ALL OF A SUDDLE THE STEERING WHEEL LOCKS UP AND THE POWER STEERING STOPS WORKING, SO YOU CAN'T HARDLY TURN IT. I CAME INCHES FROM GETTING IN A WRECK. YOU CAN UPDATE THE SYSTEM BUT IT WILL ONLY WORK FOR ABOUT 1 OR 2 YEARS.

TL* THE CONTACT OWNS A 2008 MERCURY MARINER HYBRID. WHILE DRIVING APPROXIMATELY 35 MPH, THE BRAKES FAILED. THE ANTILOCK BRAKES AND REGENERATIVE BRAKES DISABLED WARNING INDICATORS ILLUMINATED. THE CONTACT COASTED THE VEHICLE TO THE SIDE OF ROAD. THE VEHICLE WAS TOWED HOME. THE CONTACT ALSO STATED THAT THE WARNING INDICATORS ILLUMINATED APPROXIMATELY TWENTY TIMES BEFORE THE ACTUAL FAILURE. THE VEHICLE WAS TAKEN TO TWO DIFFERENT DEALERS, BUT THEY COULD NOT DUPLICATE THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VIN WAS INVALID. THE APPROXIMATE FAILURE MILEAGE WAS 131,000.
TL* THE CONTACT OWNS A 2008 MERCURY MARINER HYBRID. THE CONTACT STATED THAT THE STEERING WHEEL SEIZED AND THE POWER STEERING INDICATOR ILLUMINATED. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE POWER STEERING TORQUE SENSOR FAILED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 58,000.
QUITS RUNNING WHILE CAUTION WITH EXPLANATION IN MIDDLE LIGHT APPEARS AND WRENCH LIGHT APPEARS. THEN NOTIFICATION TO STOP AT ONCE SAFELY. THIS HAS HAPPENED ON FREEWAY. AFTER 15-20 MINUTES CAR WILL CRANK AGAIN BUT MAY ONLY GO A FEW FEET AND STALL AGAIN, NEAR DEATH EXPERIENCE.

APRIL 2016 THE ABS LIGHT WAS ON ALONG WITH THE MESSAGE "CHECK BRAKE SYSTEM AND THE REGEN BRAKES." WHEN BREAKING THE VEHICLE TOOK MUCH LONGER THAN NORMAL TO SLOW AND STOP. THE REPAIR FOR THIS WAS $4100 ($4800 WITH LABOR). I WAS ADVISED THAT THIS WAS A SAFETY ISSUE SINCE THE BRAKES WERE NOT WORKING PROPERLY AND TO NOT DRIVE THE VEHICLE. I CHOSE TO HAVE THE REPAIR SINCE I NEED THE VEHICLE FOR WORK AND STILL OWE MONEY ON IT. I DID SOME RESEARCH AND IT APEARS THAT THIS IS A KNOWN PROBLEM AS OTHER COMPLAINTS ON NHTSA AND OTHER FORUMS ATTEST TO. I CONTACTED FORD AND ASKED THAT I BE REIMBURSED AS THIS IS A SAFETY ISSUE. THEY DECLINED MY REQUEST.
UPON STARTUP AND SOMETIMES WHEN DRIVING THE ABS WARNING LIGHT WILL ILLUMINATE ALONG WITH THE SERVICE BRAKE SYSTEM AND THE REGENERATIVE BRAKE SYSTEM SHUTDOWN. CAUSING THE BRAKES TO BECOME WEAK AND INEFFECTIVE.

2DP22005 · 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
