SUMMARY:
On April 29, 2015, the Office of Defects Investigation (ODI) opened PE15-017 to investigate reports of low-mileage failures of front brake jounce hoses in model year (MY) 2015 Ford Explorer Police Interceptor vehicles operated as training vehicles by the City of Sacramento, California (ODI VOQ No. 10705832). To date, the Sacramento police fleet has reported a total of 7 front hose failures in 5 different Explorer Police Interceptor vehicles used for its Emergency Vehicle Operation Course (EVOC) training.  Most of the failures occurred within the first few miles of service on a closed course used for the EVOC program, which includes evasive accident avoidance and pursuit maneuver training.  The hose assemblies either leaked at, or pulled completely free from, the caliper-end attachment where the hose is crimped to the steel end fitting.  Most of the failures resulted in a sudden loss of braking performance that caused the vehicle to run off the intended course.  None of the failures resulted in any crashes, injuries or property damage. 

The subject MY 2015 hose assemblies are similar in design to hoses used on MY 2013 through 2014 Explorer Police Interceptor and civilian vehicles. The 5 vehicles used by Sacramento EVOC have all been repaired using MY 2016 front hose assemblies that have been changed to incorporate a short steel tube attached to the caliper end banjo block.  No failures have been experienced by the Sacramento fleet to date in the other 37 MY 2014-2015 Explorer Police Interceptor vehicles (2 MY 2014 and 35 MY 2015) used by the fleet in regular law enforcement duty cycles unrelated to the EVOC training.  In its response to ODI's information request letter for PE15-017, Ford provided information about 2 additional failures reported by other fleets, including 1 involving a Sacramento Regional Transit vehicle that occurred while being driven on the street.

Based on its analysis of failed parts returned from the Sacramento fleet and the fleet's EVOC training duty cycle, Ford attributes the Sacramento fleet hose failures to excessive temperatures produced during "hot-soak" portions of the EVOC training duty cycle (when the vehicles are stationary after hard braking exercises, with no cooling air flow through the brake rotor vents and across the other brake components).  During testing conducted to replicate the EVOC duty cycle, Ford measured temperatures at the subject crimp fittings that exceeded the design limits of the brake hose material after several successive training intervals and hot soaks.  Ford has provided the Sacramento fleet with modified replacement hose assemblies for all of its MY 2014-15 Explorer Police Interceptor vehicles.  The replacement hose assemblies were developed for use in MY 2016 Explorer vehicles and were modified slightly to accommodate the addition of a ride height sensor in those vehicles.  The revised assemblies have an additional length of brake pipe between the caliper end connection and the subject crimp ferrule that results in additional heat dissipation and makes the assemblies more robust to the severe thermal effects experienced during the EVOC testing (the hose material is the same in both assemblies).  Ford believes that the excessive temperatures experienced at the crimp fitting in the subject vehicles are unique to the EVOC duty cycle, have not been observed in the standard on-road severe duty cycle testing performed by Ford and police fleets who routinely conduct such testing and are not likely to occur in service usage for on-road Explorer Police Interceptor vehicles.

An Engineering Analysis has been opened to conduct testing and further assess the scope, frequency and safety-related consequences of the alleged defect in the subject vehicles.

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

FORD TRANSMISSIONS THAT SUDDENLY DOWNSHIFT UNDER INVESTIGATION


December 28, 2017 Ford transmissions that suddenly downshift are under investigation in nearly 1.4 million 2011-2013 Ford F-150, Ford Expedition and Lincoln Navigator vehicles.

The National Highway Traffic Safety Administration (NHTSA) says the transmissions can unexpectedly downshift to 1st gear without warning, something that has caused at least two crashes.

Ford recalled some of the vehicles in 2016
for the same downshifting problems allegedly caused by output speed sensors. However, NHTSA says 123 complaints have been filed by F-150, Expedition and Navigator owners since the 2016 recall.

Many owners say they have experienced the sudden downshifting of the transmissions, but their vehicles weren't included in the 2016 recall. Other owners complain they had the recall repairs performed but the transmission problems continued.

Two of those 123 complaints came from 2012 Ford F-150 owners, one who said his truck wasn't included in the previous recall.

Rather have sensor issues than hard parts failure, LOL

FORD 'DOOR AJAR' LIGHT CLASS-ACTION LAWSUIT MAKES HEADWAY
Lawsuit alleges Ford vehicles have defective door latch sensors that Ford concealed from owners.  Z

NOVEMBER 13, 2018 — A Ford "door ajar" light class-action lawsuit is moving forward as a federal judge granted in part and denied in part Ford's motion to dismiss the complaint.

According to the lawsuit, the vehicles are equipped with door latch mechanisms that cause sensors to wrongly indicate a door is open when it's really closed. Contaminated sensors allegedly cause "door ajar" warning lights that normally indicate the doors aren't completely closed.

Included in the door latch lawsuit are these models:

2011-2016 Ford Edge
2012-2014 Ford Flex
2013-2014 Ford Explorer
2011-2013 Lincoln MKX
2013 Lincoln MKT. 

The "wetting current" is "the minimum electric current needed to flow through an electrical contact to break through the surface film resistance on the contact" and to prevent oxidation that may occur from humidity and exposure to moisture. But the lawsuit alleges the wetting current is too low to clean the sensors, resulting in faulty "door ajar" warnings.

The dirty sensors allegedly interfere with accurate voltage readings which "triggers an audible warning, activates a visual warning on the instrument panel, and sends out a visual intermittent 'shift to park' message" because the faulty sensor causes the computer system to mistakenly believe the vehicle has stopped .
