PARKING BRAKE ENGAGEMENT/ADJUSTMENT THE EMERGENCY BRAKE DOES NO ENGAGE WHEN THE HANDLE IS PULLED UP DUE TO A SLACK IN THE CABLE LINE OF ABOUT 2 INCHES. THIS CAUSES AN ISSUE DRIVING AS THE SENSOR IS ENGAGED AND CAN CAUSE CRUISE CONTROL TO TURN OFF. ALSO, IT BECOMES A RISK PARKING THE CAR ON A HILL SINCE YOU HAVE TO PULLED THE HANDLE ALL THE WAY UP FOR PROPER TENSION ON THE BRAKE LINE CABLE. THE OTHER ISSUE IS THIS CABLE CAN COME LOOSE RESULTING IN LOST OF THE EMERGENCY BRAKE FUNCTION. ALSO, IT CAN CAUSE VIBRATION AND RATTLING SINCE THE CABLE MOUNT AND BOLTING CAN MOVE AGAINST THE TRANSMISSION CASING. FORD SHOULD CREATE A TSB FOR THIS ISSUE AND NOTIFY DEALERS TO LOOK FOR IT DURING REGULAR MAINTENANCE SINCE MULTIPLE USERS HAVE HAD THIS ON INTERNET FORUMS. 1)HTTP://WWW.MUSTANG6G.COM/FORUMS/SHOWTHREAD.PHP?T=25204&HIGHLIGHT=BRAKE 2)HTTP://WWW.MUSTANG6G.COM/FORUMS/SHOWTHREAD.PHP?T=54010&HIGHLIGHT=PARKING+BRAKE

BOTH TIMES THEY SAID I WOULD NEED A NEW ENGINE. BUT, I JUST RECEIVED A CALL FROM THEM LAST FRIDAY ON 10-21-16 AND THEY SAID THEY ARE NOT GOING TO BE PUTTING A NEW ENGINE IN THE CAR AS THEY FEAR THE NEW ENGINE WILL DO THE SAME THING. THEY SAID THEY "MAY HAVE A FIX NEXT SPRING." I CALLED FORD CUSTOMER SERVICE AND THEIR REGIONAL REP CALLED ME BACK. SHE ONLY OFFERED ME A MAINTENANCE PLAN FOR FREE OIL CHANGES. THIS IS WORTHLESS TO ME AND MY CURRENT PROBLEM AS IT DOESN'T NEED OIL CHANGES AND DOES NOTHING TO ADDRESS THE PROBLEM. SINCE THEY ADMIT THEY HAVE A PROBLEM WITH THE ENGINE AND HAVE NO REPAIR FOR IT, I ASKED THEM TO BUY THE CAR BACK. THEY REFUSED.

I USED TWO DIFFERENT STYLES OF TORQUE WRENCH TO CONDUCT MY TEST. ONE TYPE WAS USED TO LOOSEN TEN LUG NUTS AND ANOTHER WAS USED TO LOOSEN THE REMAINING TEN. MY INTENT WAS TO RULE OUT ANY GROSS ERROR IN TORQUE READINGS. TO MY KNOWLEDGE THE WHEELS HAVE NEVER BEEN REMOVED FROM THE VEHICLE, THEREFORE I SEE THREE POSSIBILITIES: THE DEALER REMOVED THE WHEELS FOR SOME REASON AND DID NOT TORQUE TO SPECIFICATION OR THE LUG NUTS ARE LOOSENING THEMSELVES EVENLY OR THEY WERE NOT TORQUED TO SPECIFICATION FROM THE FACTORY. I FEEL THE MOST LIKELY SCENARIO IS THAT THEY WERE NOT TORQUED TO SPECIFICATION FROM THE FACTORY.

25V614000 · Seat Belts:pretensioner

Sep 12, 2025

Ford Motor Company (Ford) is recalling certain 2015-2017 Mustang vehicles. Water and road salt may corrode the front seat belt anchor pretensioner cables.

Consequence & remedy

Consequence: A corroded cable can break, preventing the seat belt from properly restraining an occupant, and increasing the risk of injury during a crash.

Remedy: Dealers will inspect and replace both front seat belt anchor pretensioner assemblies, as necessary. In addition, dealers will remove sections of the carpet and underlayment that contact the cables. Dealers will also inspect the A-pillar sealing patches, and as necessary, install A-pillar body plugs, and/or inspect and replace the front outboard seat bolts. Repairs will be performed free of charge. Interim letters, notifying owners of the safety risk, were mailed October 20, 2025. Additional letters will be sent once the final remedy is available, anticipated December 2026. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 25S92. Vehicle Identification Numbers (VINs) involved in this recall became searchable on NHTSA.gov September 17, 2025.

EA21002 · Desiccated Air Bag Inflator Rupture

Opened Sep 17, 2021 · No close date supplied

Status: open (inferred from source dates) · Air Bags:frontal:driver Side:inflator Module; Air Bags:frontal:passenger Side:inflator Module

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.
