2008 Mercury Mariner Hybrid

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.

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

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?

"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.
