WHILE DRIVING DOWN THE HIGHWAY, THE VEHICLE FLASHED SERVICE ADVANCE TRAC, DOWN HILL DESCENT CONTROL FAULT, TRAILER BRAKE MODULE FAIL AND A COUPLE MORE CODES. ALL ELECTONICS IN VEHICLE WENT BLANK, INCLUDING ALL CONTROLS/GAUGES. BEFORE DOING SO, LAST CODE READ, SHIFT TO PARK. ALMOST CAUSED ME TO HAVE AN ACCIDENT, BECAUSE THE POWER STEERING WENT OUT AND NEARLY PULLED ME INTO ANOTHER VEHICLE. THE ACCELERATION IS BAD TOO, FEELS LIKE IT IS NOT FIRING ALL CYLINDERS AGAIN. HAVE ALREADY TAKEN IN FOR A NUMBER OF ISSUES, INCLUDING CRANKSHAFT SENSOR ISSUES(WAS LOSING POWER TO DRIVELINE); BRAKES LOCKING UP (HAVE REPLACED THE ROTORS AND PADS SIX TIMES AND LAST TIME I REPLACED BOTH CALIBERS AS WELL; POWER STEERING HAS BEEN REPLACED ONCE BEFORE, FRONT AXLES AND BEARINGS REPLACED. AS WELL AS, AC PROBLEMS. WHEN THE FIRST ISSUES AROSE, I WAS TOLD BY SERVICE TECH AT DEALERSHIP I NEEDED A NEW ENGINE, (LATER HE COMPLETELY DENIED TELLING ME THIS) INSTEAD THEY FIXED SOME THINGS AND GAVE IT BACK TO ME. PROBLEMS HAVE CONTINUED SINCE, LIKE I SAID HAVE TAKEN IT IN AT LEAST 6 TIMES TO A DEALER AND ONCE TO AN INDEPENDENT MECHANIC. AT FIRST THE PROBLEMS WERE COVERED BY WARRENTY, NOW THEY ARE NOT, THERE IS ONLY 78,000MILES ON THE TRUCK AND HAS BEEN IN SHOP AT LEAST 6 TIMES AND IS ONLY 4 YRS OLD. NOT SURE WHAT TO DO, AS THE PROBLEMS RESEMBLE RECALL ISSUES, BUT DEALERSHIP SAYS THEY AREN'T PART OF ANY RECALLS. CONCERNED FOR MY SAFETY ON THE ROAD.

RQ17010 · Unexpected Transmission Downshift

Opened Dec 25, 2017 · Closed Oct 22, 2019

Status: closed (inferred from source dates) · Power Train:automatic Transmission; Power Train:automatic Transmission:control Module (tcm/pcm/tecm)

The Office of Defects Investigation (ODI) opened an investigation based on consumer allegations of transmissions unexpectedly downshifting to a lower gear without input from the driver on model year (MY) 2011-2013 Ford F-150, Expedition and Navigator vehicles. ODI has received 455 unique reports related to the alleged problem that were not covered under a previous recall for this issue (16V-248).Expedition and Navigator complaint rates are lower than F-150 complaints. Of those 455 reports, 34.7% claimed that the rear wheels locked up when the transmission downshifted. There were 4 accident claims with no injuries. There are many instances where drivers report leaving their lane or the road because of this issue.In response to ODI's Information Request (IR) letter, Ford Motor Company (Ford) responded with 783 unique reports related to the alleged problem. There were 6 accident claims with 3 injuries. Ford also submitted 1206 warranty claims related to transmission downshifting failures. The failure can occur at any time, but typically at higher speed, and include symptoms such as sudden transmission downshifting, loss of speedometer, erratic shifting of transmission, and transmission stuck in one gear. The failures typically occur without warning and may result in the rear wheels momentarily locking up. The driver often had to fully stop the vehicle and restart it to get the vehicle to shift properly.On February 2nd, 2019 Ford notified ODI that it would conduct a safety recall (19V-075) to remedy transmission downshifting failures on all 2011-2013 F-150 vehicles. Ford will also offer extended warranties to 2011-2013 Expedition and Navigator vehicles with the same issue. Per Ford, some vehicles may experience an intermittent loss of Transmission Output Speed Sensor (OSS) signal to the Powertrain Control Module (PCM), potentially resulting in a temporary unintended downshift into first gear. Ford will reprogram the PCM with software that will prevent an unintended downshift into first gear and illuminate the Malfunction Indicator Light in the event of an intermittent OSS signal loss.The recall action initiated by the manufacturer appears to address the safety risks of concern to ODI.Accordingly, the investigation is closed.The ODI reports cited above can be reviewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the identification (ODI) numbers found in the attached list.

PE16003 · Master Cylinder External Leak

Opened Feb 29, 2016 · Closed Jul 26, 2016

Status: closed (inferred from source dates) · Service Brakes; Service Brakes, Hydraulic; Service Brakes, Hydraulic:fluid; Service Brakes, Hydraulic:foundation Components:master Cylinder

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

PE13018 · Reduced Power During Hard Acceleration

Opened May 22, 2013 · Closed Apr 7, 2014

Status: closed (inferred from source dates) · Engine; Engine And Engine Cooling

On May 22, 2013, the Office of Defects Investigation (ODI) opened PE13-018 to investigate 95 complaints alleging incidents of reduced engine power during hard accelerations in model year (MY) 2011 through 2013 Ford F-150 trucks.ODI was aware of three technical service bulletins (TSBs) issued by Ford for a condition that was related to moisture accumulation in the Charge Air Cooler (CAC) for the turbochargers.A Preliminary Evaluation was opened to gather information to assess whether the subject vehicles contain a safety related defect.The subject vehicles are powered by Ford?s 3.5L EcoBoost engine which uses twin turbochargers to obtain a balance of fuel economy and engine power based on the driver?s demand.When the driver requests more power from the engine, as in accelerating to pass, merge, ascend hills or haul a load the two turbochargers will spin up compressing the air which is then used to increase the power created by the combustion in the engine.The compressed air, which gains heat by the compression process, is passed through a Charge Air Cooler (CAC) which is designed to lower the temperature of the air in order to make the combustion process even more efficient (Figures 1 and 2).In response to ODI?s Information Request letter, Ford indicated that a misfire condition could occur after steady-speed operation under significantly humid and rainy conditions.Ford?s analysis found that under those conditions, condensation could form and accumulate on the inside of the CAC tubes which could then be ingested into the engine during particularly hard acceleration near wide-open throttle.An engine misfire of up to three cylinders could occur if the amount of condensed water released from the CAC exceeded the engine?s operating threshold for water ingestion.Ford noted that due to regulations set by the EPA, the powertrain software would disable up to two of the misfiring cylinders for no more than 30 seconds and until the driver tips out the throttle in order to protect the catalytic converter from damage. Ford?s testing of this condition on the subject vehicles showed that a vehicle experiencing such a condition would continue to maintain its speed as well as accelerate, albeit at a lower rate than expected by the driver.Similar results were obtained in testing done by NHTSA?s Vehicle Research and Testing Center in East Liberty, Ohio (Figure 6).In an ongoing process to address the problem Ford issued a series of TSBs where a deflector shield was installed onto the CAC (Figures 3, 4 and 5).In January 2014 Ford indicated that its data shows that the TSBs have been effective in resolving the problem, that for the MY 2013 vehicles their remedy is 100% effective and the latest TSBs for MY 2011 ? 2012 are 95% effective.The 525 complaints to ODI and the total 4,120 unique VIN complaints listed in the Failure Report are incidents of alleged reduced power or driveability symptoms and not all are necessarily related to the condition created by water ingestion.Reduced power conditions can occur for a variety of reasons including faults with ignition coils, spark plugs, a catalytic converter, the throttle body, turbocharger, fuel pump/filter, powertrain control module (hardware or software) or transmission shifting problems.Ford also noted that in a large number of warranty claims on the subject vehicles, the CAC was replaced or a TSB procedure was performed when the symptoms exhibited were inconsistent with a CAC water ingestion related issue.Given these circumstances, further use of the agency resources in this matter does not appear to be warranted.Accordingly, this investigation is closed.The closing of

Ford?s testing of this condition on the subject vehicles showed that a vehicle experiencing such a condition would continue to maintain its speed as well as accelerate, albeit at a lower rate than expected by the driver.Similar results were obtained in testing done by NHTSA?s Vehicle Research and Testing Center in East Liberty, Ohio (Figure 6).In an ongoing process to address the problem Ford issued a series of TSBs where a deflector shield was installed onto the CAC (Figures 3, 4 and 5).In January 2014 Ford indicated that its data shows that the TSBs have been effective in resolving the problem, that for the MY 2013 vehicles their remedy is 100% effective and the latest TSBs for MY 2011 ? 2012 are 95% effective.The 525 complaints to ODI and the total 4,120 unique VIN complaints listed in the Failure Report are incidents of alleged reduced power or driveability symptoms and not all are necessarily related to the condition created by water ingestion.Reduced power conditions can occur for a variety of reasons including faults with ignition coils, spark plugs, a catalytic converter, the throttle body, turbocharger, fuel pump/filter, powertrain control module (hardware or software) or transmission shifting problems.Ford also noted that in a large number of warranty claims on the subject vehicles, the CAC was replaced or a TSB procedure was performed when the symptoms exhibited were inconsistent with a CAC water ingestion related issue.Given these circumstances, further use of the agency resources in this matter does not appear to be warranted.Accordingly, this investigation is closed.The closing of
