OPENED MY DOOR PASSENGER SIDE AND MY GLOVE COMPARTMENT WAS THE SOURCE SO I OPEN IT AND ALL I SAW WERE FLAMES LEAPING FROM THE TOP OF THE COMPARTMENT AND FLAMES COMING OUTTA THE AIR VENTS. WITHIN MINUTES THE ENTIRE GLOVE BOX COMPARTMENT AS WELL AS THE DASH ITSELF MELTED ONTO THE FLOORBOARD. SOME GENTLEMAN FOUND A FIRE EXTINGUISHER AND PUT IT OUT BEFORE THE FIRE DEPARTMENT EVEN ARRIVED. IM JUST LUCKY I WASN'T IN IT BUT THIS HAD TO BE SOME MANUFACTURE DEFECT IN THE WIRING BECAUSE I BELIEVE THAT IT STARTED ABOVE THE GLOVE BOX RIGHT WERE THE WIRE HARNESSES ENTER THE CAR THROUGH THE FIRE BREAK BETWEEN THE CAR AND ENGINE COMPARTMENT.

AFTER ABOUT 8 MONTHS OF PURCHASE OF THIS VEHICLE THE BACKUP CAMERA BEGAN TO ACT UP. THE CAMERA WOULD OCCASIONALLY GO TO STATIC OR A COMPLETELY BLACK SCREEN. I HAD FINALLY MANAGED TO HAVE TAKEN A VIDEO AND PRODUCED IT FOR THE MECHANIC TO SEE. THEY SAID THAT THEY COULD NOT RECREATE THE ISSUE SO THEY HAD BLAMED THE PROBLEM ON THE HEAT. WHILE I AGREE IT IS HOT IN THE STATE OF ARIZONA, THIS IS SOMETHING THAT SHOULD HAVE BEEN SORTED OUT DURING THE DEVELOPMENT CYCLES OF THE VEHICLE AND THE CAMERA. ARIZONA THE LAST I CHECKED IS A PART OF THE UNITED STATES WHERE FORD EXISTS AS A COMPANY AND ROAD TESTS VEHICLES ON ACCOUNT OF THE HEAT. THESE ARE SITUATIONS THAT SHOULD HAVE BEEN FIGURED OUT ALREADY. YOU ARE NOT EXPECTED TO RELY ON BACKUP CAMERAS, BUT IN A VEHICLE LIKE THIS IT IS AN IMPORTANT WAY OF BEING ABLE TO SEE OUT THE BACK OF THE CAR AND IS A PREMIUM ITEM. THIS IS ONE OF FOUR COMPLAINTS I HAVE HAD ABOUT THIS VEHICLE THAT HAVE NOT BEEN RESOLVED.

SYNC GOES OUT FAIRLY REGULARLY INCLUDING PHONE FUNCTION, BACK UP CAMERA, STEREO. CURRENTLY IN SHOP AGAIN SINCE 7-3-17 @ 9 AM.(16 CONSECUTIVE DAYS THIS TRIP). SAFETY CONCERN OF MOST IMPORTANCE TO ME IS THE FACT THAT CAR HAS LOST POWER MULTIPLE TIMES ON HIGHWAY AND THANKFULLY HAS NOT YET BEEN IN A MAJOR ACCIDENT. QUICK REFLEXES OF DRIVERS BEHIND ME ARE ONLY REASONS THAT ACCIDENTS HAVE BEEN AVOIDED THUS FAR. I AM TOLD BY DEALER THAT THIS IS A THROTTLE BODY MALFUNCTION. THROTTLE BODY HAS BEEN REPROGRAMMED AFTER A NEAR REAR END ACCIDENT ( HIGHWAY/ INTERSECTION/TURN). THROTTLE BODY WENT OUT WITH NO WARNING CAR INSTANTLY DECELERATED WITH NO ACCELERATION CAPABILITY. ONE WEEK LATER THROTTLE BODY FAILS AGAIN CAUSING A NEAR ACCIDENT THAT WOULD HAVE BEEN FATAL IN NATURE DUE TO THE SPEED OF TRAFFIC ON HIGHWAY. MY 7 YEA OLD WAS IN REAR SEAT. MY CHILDREN ARE NO LONGER FOR ANY REASON ALLOWED IN THE VEHICLE SINCE OCTOBER 2016. THROTTLE BODY HAS YET AGAIN BEEN REPLACED JUNE 2017. THIRD ATTEMPT TO REPAIR THIS CAR WITH NO INDICATION THAT THIS IS A REPAIR, IT SEEMS TO BE MERELY A REPAIR ATTEMPT AS THIS PROCESS OF ATTEMPTED REPAIRS HAS CAUSED 3 NEAR REAR ACCIDENTS. THIS CAR HAS PROVEN ITSELF TO BE A DANGER ON THE ROAD AND A MAJOR SAFETY HAZARD FOR ANYONE INSIDE OR OUTSIDE OF THIS VEHICLE WHILE IT IS IN MOTION. LOW MILEAGE IS INDICATOR OF HOW UNTRUSTWORTHY VEHICLE IS TO ME. IT IS ONLY DRIVEN BY ME, NO PASSENGERS ALLOWED. ONLY DRIVEN IF ANOTHER CAR CAN NOT BE BORROWED. UNRESOLVED ISSUES.

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.
