 In a letter dated august 30, 2012, the north carolina consumers council (nccc) petitioned the national highway traffic safety administration (nhtsa) to initiate a defect investigation of alleged electronic throttle body failures resulting in engine stall or surge while driving in model year (my) 2005 through 2012 ford escape vehicles.on october 2, 2012 the office of defects investigation (odi) opened a defect petition dp12-006 to evaluate whether to grant or deny the petition. the petition is hereby granted on certain model years.the nccc letter cites two complaints of stall while driving in my 2009 ford escape vehicles that were diagnosed as failed throttle bodies with diagnostic trouble codes (dtc) p2111, throttle body stuck open, and p2112, throttle body stuck closed. the petitioner indicates that the owners of both vehicles reported experiencing repeated incidents of stalling and engine surging.according to ford, escape non-hybrid vehicles are equipped with electronic throttle body (etb) assemblies beginning with my 2009.vehicles manufactured between june 22, 2009 and october 15, 2009 may contain contaminated printed circuit boards (pcb) with plating variations. plating variations could lead to a lack of continuity in the throttle position sensor circuit where p2111 and/or other dtcs would be generated and stored.ford and its electronic throttle body supplier, delphi, modified the pcb manufacturing process and issued a technical service bulletin (tsb) 09-23-5.vehicles produced after october 15, 2009 incorporated etbs manufactured with a pcb process that resolved this condition.odi's analysis identified a total of 123 unique reports indicating allegations of reduced motive power or vehicle stall.depending on the condition of throttle control system malfunction, a driver may experience varying levels of reduced engine performance associated with three limp home modes.in two limp modes, reduced engine performance may maintain vehicle speeds above 20mph while the third is a limited limp home mode with engine speeds limited to approximately 900 rpm. allegations of stall appear to be related to the limited limp home mode.vehicles are not likely to unexpectedly stall as a result of this condition, but drivers may characterize the reduced functionality as a stall, even though their vehicle may still has motive capability.allegations of vehicle surge appear to be related to limp home mode operation.complaints alleging surge are most likely related to engine rpm fluctuations at low vehicle speeds or idle as the control system engages to prevent engine stall.in limited limp mode, rough-idle conditions may exist while the control system attempts to modulate engine rpms once the vehicle reaches a reduced speed to maintain approximately 900 rpm.separately, odi received 59 complaints alleging incidents of engine stall while driving in model year (my) 2010-2011 ford fusion vehicles.approximately 60 percent (36) of the incidents occurred at speeds of 40 miles per hour or more.eighty percent of complaints (47) were received beginning march 2012 and 14 complaints reported that the throttle body was replaced or dtcs associated with limp home modes. additionally, ford issued tsb 10-21-6 addressing dtcs associated with idle speed drops and limited limp home mode.the complaints show an apparent increasing trend.a preliminary evaluation has been opened to assess the scope, frequency and potential safety consequences associated with the alleged defect.see additional information for the voqs associated with the opening of this investigation.

 This vehicle has lost brakes 3 times. my now 17 year old daughter is the driver! the first time the brake pedal went to the floor and pumping it would not help. putting the car in neutral and using the emergency brake was the only way to stop the car. a non-ford car technician told us it was a possible brake booster issue and the best thing to do would be for it to happen again and bring it to ford for the codes to be read. i drove the car for over a week and it would not repeat the probelm. the second time was also around 40 mph and pushing the brakes as hard as posible would only slightly stop the car and it would keep jumping forward. my daughter had to stop with the e-brake. i took it to ford for diagnosis and repair. ford replaced the vacuum pump/hose assembly. then 2 days later, she lost brakes again. had to use e-brake to stop in busy traffic. the southeast region ford technician came to diagnosis this car. after 9 days at the shop the brake booster assembly was replaced. we have been told again that this should take care of the problem. fyi ( each time the car lost brakes, by turning off the car and back on agian it would regain them). i am now driving this car to determine if the issue is in fact taken care of. this has been a very scary situation - especially since my daughter is the driver of this vehicle. when reading automobile blogs it appears brakes are an issue not only with the mariner hybrid, but the escape hybrid as well. i would like this investigated.
STEERING

 The steering locked for 1 to 2 seconds during a right hand turn on an entrance ramp to a highway. it happened again 2 months later with the steering locking for 1 to 2 seconds on a left hand turn after stopping at a stop sign.
08/11/201131000
 Power steering cut out, quit working, on left turn, speed about 10 mph. outage lasted about 1-2 seconds. believe would have hit far side curb if steering had not spontaneously recovered. this was first occurrence. drove car directly to dealer from incident; diagnosis tbd. afraid to drive. at higher speed or if had lasted just a little longer would have wrecked!
