AFTER TURNING ON THE REAR DEFROSTER FOR ABOUT 2-3 MINUTES THE RIGHT REAR WINDOW SHATTERED. (IF LOOKING FROM BEHIND ITS THE FAR RIGHT OUT OF THE 3 PART WINDOW. ) ITURNED IT ON AND DROVE ON A STRAIGHT ROAD FOR 1/4 TO 1/2 MILE AT APROX 35 MPH. WE HEARD A LOUD POP/BANG AND LOOKED AROUND AND FOUND THE SHATTERED WINDOW. NO PUNCTURE MARK OR HOLE FROM ANY OBJECT HITTING IT. APPARENTLY THIS IS A COMMON PROBLEM ACCORDING TO REVIEWS AND NEWS ARTICLES AS THERE IS A DEFECT IN THE DEFROSTER OVER HEATING. LUCKILY IT STAYED IN THE WINDOW SO WE DO NOT HAVE GLASS EVERY WHERE BUT IT COULD FLY OUT EVERY WHERE AT ANY SECOND. THIS IS EXTREMELY DANGEROUS, ESPECIALLY IF YOU HAVE A CHILD IN THE BACK.
REAR DEFROSTER WORKED SOMETIMES AND SOMETIMES NOT NOW IT STOPPED COMPLETELY AFRAID IT WILL START ON ITS OWN AND SHATTER MY WINDOW I HAVE MY TWO GRANDKIDS IN THE BACK EVERY DAY AFRAID THEY WILL BE HARMED IF IT SHATTERS OR CATCH ON FIRE DUE TO THE SHORT WHY NO RECALLS TO FIX THE PROBLEM.

AFTER HAVING MY TRUCK FAIL TO START SEVERAL TIMES I DISCOVERED IT WAS A "FUSE 27" ISSUE WITH THE TRUCK. THIS ISSUE IS SO PREVALENT THAT THE FORD DEALER KNEW THE ISSUE BY NAME AS SOON AS I DESCRIBED IT. THE FUSE, LOCATED IN SLOT 27 OF THE MAIN FUSE PANEL WAS SEVERELY BURNED AND CHARRED FROM AN OVERLOAD ISSUE THAT CAUSES THE FUSE TO BURN IN ITS SOCKET INSTEAD OF TRIPPING LIKE A FUSE IS DESIGNED. AFTER RESEARCHING THE ISSUE, I DISCOVERED THIS IS A KNOWN ISSUE TO FORD (TSB 15-0137) AND HUNDREDS, POSSIBLY THOUSANDS OF FORD F-150 VEHICLES ARE AFFECTED WITH THIS ISSUE. THIS ISSUE IS A POTENTIAL FIRE HAZARD TO THE VEHICLE, OR COULD CAUSE LOSS OF POWER AT HIGHWAY SPEEDS. FORD IS CHOOSING TO RELEASE A TSB AND A REPAIR KIT, AND CHARGE CUSTOMERS TO FIX THEIR FAULTY WIRING IN THEIR NEW VEHICLES INSTEAD OF A RECALL OR WARRANTY COVERAGE OF A KNOWN ISSUE THEY ARE NOT FIXING. THIS IS DANGEROUS AND IRRESPONSIBLE ON FORD'S PART. *TR

2RQ24005 · Unintended Transmission Downshift
Opened Mar 27, 2024 · Closed Jul 29, 2024
Status: closed (inferred from source dates) · Power Train:automatic Transmission:control Module (tcm/pcm/tecm)
In September 2016, Ford Motor Company (Ford) issued safety recall 16V-248 which included certain model year (MY) 2011-2012 Ford F-150 vehicles equipped with 6-speed (6R80) automatic transmissions. This recall was in response to allegations of unintended, unexpected vehicle transmission downshifting to a lower gear without warning, often accompanied by temporary rear wheel lock-up, increasing the risk of a crash and/or injury, and included approximately 153,581 vehicles. Ford identified the root cause of the unintended, unexpected vehicle transmission downshifting to a lower gear to be intermittent signal loss from the transmission’s Output Shaft Speed (OSS) sensor due to solder joint cracks on the OSS circuit board as a result of manufacturing process issues. The OSS sensor is mounted onto the molded lead frame and transmits changes in transmission shaft speed to the Powertrain Control Module (PCM). The remedy program described in safety recall 16V-248 involved reprogramming of the PCM to prevent unintended vehicle transmission downshifting from occurring. In December 2017, the Office of Defects Investigation (ODI) opened a Recall Query (RQ17-010) to assess the scope and remedy effectiveness of safety recall 16V-248. As a result of this ODI investigation, Ford issued safety recall 19V-075 to expand the scope of 16V-248 to include MY 2011-2013 Ford F-150 vehicles equipped with 6-speed (6R80) automatic transmissions and included approximately 1,263,051 vehicles. The remedy program described in safety recall 19V-075 involved reprogramming of the PCM to prevent unintended vehicle transmission downshifting from occurring. In June 2019, Ford issued safety recall 19V-433 as the remedy program used to service MY 2013 Ford F-150 5.0L and 6.2L vehicles in accordance with safety recall 19V-075 did not contain the necessary updates to prevent unintended vehicle transmission downshifting from occurring and included approximately 107,857 vehicles. On March 27, 2024, ODI opened this Recall Query (RQ24-005) to investigate the scope of the above-described safety recalls. At the time that this investigation was opened, ODI had received 86 Vehicle Owner Questionnaires (VOQs) reporting allegations of unintended, unexpected vehicle transmission downshifting to a lower gear without warning, often accompanied by temporary rear wheel lock-up, in MY 2014 Ford F-150 vehicles. As a result of this Recall Query, Ford filled safety recall 24V-444 on June 14, 2024, to include MY 2014 Ford F-150 vehicles and expand the scope of safety recalls 16V-248, 19V-075 and 19V-433. The remedy program described in safety recall 24V-444 involved reprogramming of the PCM to prevent unintended vehicle transmission downshifting from occurring and included approximately 552,188 vehicles. In its May 2024 response to ODI’s information request, Ford concluded that a predominant root cause for the intermittent OSS signal loss has not been identified outside of the original safety recall (16V-248). Ford’s investigation also concluded that the primary causes of the defect in MY 2014 F-150 vehicles were related to the molded lead frame and the control assembly transmission main. In the May 2024 response, Ford identified 2,184 total reports that described unintended vehicle transmission downshifting and rear wheel lock-up events; 1,441 warranty claims and 743 reports from consumer complaints, field reports, consumer surveys, and lawsuits/legal claims. Note that the values presented here and in the table above represent the total number of reports which can include a single consumer with multiple reports of the same event as well as a consumer with reports of multiple distinct events. Of the 1,441 warranty claims, 551 warranty claims involved repair of the molded lead frame (38%) and 509 warranty claims involved repair of the control assembly transmission main (35%). Ford has also stated that the PCM programming used to prevent unintended vehicle transmission downshifting was implemented starting with MY 2015 vehicle #1 production and onward. In view of the safety recall action being taken by Ford, ODI is closing this Recall Query (RQ24-005). The agency reserves the right to take additional action if warranted by future circumstances. To review the reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

On May 23, 2016, Ford Motor Company (Ford) submitted a Defect Information Report (DIR) to NHTSA regarding a master cylinder defect that could result in loss of the front brake circuit in approximately 225,012 model year 2013 through 2014 Ford F-150 vehicles equipped with 3.5-liter GTDI engines and built at the Dearborn Truck Plant from August 1, 2013 through August 22, 2014; and the Kansas City Assembly Plant from August 1, 2013 through August 31, 2014 (NHTSA Recall #16V-345, Ford Recall #16S24).Ford indicated that the rearmost cup seal in the brake master cylinder may roll, resulting in leakage from the brake fluid reservoir to the brake booster.According to Ford's DIR, Depending on the amount of brake fluid loss from the brake master cylinder into the brake booster, the driver will experience an audible chime, message center alert, red brake warning light in the instrument cluster and may begin to experience a change in brake pedal travel and feel.In the event that a loss of brake fluid is substantial enough to reduce brake function to the front wheels, the driver may experience longer pedal travel, increased pedal effort, and extended stopping distance, increasing the risk of a crash.Full braking function would remain in the rear wheel brake circuit.Ford's recall will replace the master cylinder and, if the master cylinder is leaking, also replace the brake booster.Seventy-three (73) of the complaints received by ODI contained vehicle identification number (VIN) information required to determine date of build and recall applicability.ODI's analysis found that 66 complaints to ODI and 278 complaints to Ford involving vehicles built in the range covered by 16V-345, resulting in an overall complaint rate of 152.9 incidents per 100,000 vehicles.Twelve (12) crash incidents were reported, including 11 with VIN information.All 11 crash incidents with VIN information reported involve vehicles covered by Ford's recall.ODI's analysis identified 7 ODI complaints and 36 Ford complaints in the 194,139 subject vehicles built outside of the build range for 16V-345, resulting in a complaint rate of 22.1 incidents per 100,000 vehicles.Ford indicated that warranty return analyses identified issues with minor internal leakage between circuits due to internal contamination caused by supplier assembly plant cleanliness concerns in these vehicles.Ford assessed the internal leak condition as an early-life condition with minimal safety risk that does not result in loss of fluid or circuit failure.ODI will continue to monitor complaints in subject vehicles not included in 16V-345.No complaints have been identified in MY 2013 through 2014 Ford F-150 vehicles equipped with other engine options.The recall action initiated by the manufacturer appears to address the safety risks identified by this investigation.This preliminary evaluation is closed.The ODI reports cited above can be reviewed at http://www-odi.nhtsa.dot.gov/owners/SearchSafetylssues under the following identification numbers:10870768, 10870747, 10870511, 10870395, 10870055, 10869981, 10865843, 10865521, 10865342, 10865043, 10864862, 10864714, 10864360, 10863982, 10863527, 10862333, 10862047, 10861735, 10861190, 10860378, 10860118, 10855381, 10855356, 10854785, 10853751, 10853295, 10853012, 10852349, 10852134, 10852037, 10851317, 10851268, 10851109, 10850015, 10849862, 10846488, 10846335, 10846193, 10846006, 10840414, 10840377, 10839994, 10839985, 10839981, 10839833, 10839825, 10839816, 10838782, 10838510, 10818273, 10817706, 10809601, 10788886, 10788369, 10785526, 10779854, 10776834, 10766291, 10762034, 10761412, 10760663, 10758997, 10750065, 10749886, 107
