Me and my wife purchased a vehicle from a private seller to use for personal commute. A month later we started to notice more issue were occurring with the car then stated from the seller. I took it to an auto body shop to get it inspected and possibly serviced and upon that inspection the clerk stated that there was a milage adjustment done to the vehicle. We contacted the seller to try and return the vehicle and receive our money back, but the dealer refused and requested us to resell it.
The passenger side of the subframe has holes and will veer hard right when it brakes
Power Steering assist fault went out with no warning. Now steering wheel is locking up while driving. Also when trying to gain speed the vehicle bogs out.
Repair instructions and other communications the manufacturer sent dealers about known issues. A TSB is not a recall, and the repair is usually free only while the car is under warranty; ask your dealer for the bulletin number.
These SKUs are Exhaust Manifolds with Catalytic Converters. The customer communication requested return of unsold inventory due to a loss of CARB certification. These SKUs can no longer be sold as they do not meet CARB standards, but parts on vehicles are not effected.

Some 2010-2020 vehicles may exhibit distorted glass with a subtle orange peel pattern or streaking etched into the surface. This is caused by hydrofluoric acid which is used in some car wash solutions as a cleaning agent. Hydrofluoric acid can attack the glass and cause visual distortion and/or discoloration on the outer surface which cannot be removed by further cleaning. If this type of distortion is found, inspect the area of the glass that is covered by the cowl and/or molding. The portion of glass that is covered by the cowl or molding will not be affected by the acid. Hydrofluoric acid d
On vehicles equipped with an automatic transmission it is imperative that the converter pilot hub be greased with Motorcraft Multi-Purpose Grease Spray XL-5-A even if grease was not applied from the factory. Also verify that the engine/transmission alignment dowel pins are present as well as the engine crankshaft dowel pin, if equipped, when installing the transmission. Failure to adequately lubricate the converter hub greatly increases the likelihood of the flexplate cracking in the future. Missing dowels may cause a misalignment issue also resulting in a premature failure. Refer to Workshop

The Powertrain Control/Emissions Diagnosis (PC/ED) manual has been revised for diagnosing electronic throttle bodies (ETBs). The ETC_ACT and ETC_DSD PIDs should not used to diagnose possible ETB concerns. The IDS has a limited refresh rate when reading these PIDs and cannot display quickly enough to validate a concern. The PCM automatically monitors these inputs more accurately and will set diagnostic trouble codes (DTCs) when appropriate. Using these PIDs for diagnostics will lead to inaccurate results and improper ETB replacements. If a concern is intermittent and no DTCs are present, refer
6F35 TRANSMISSION - FLUID LEAK AT LEFT SIDE HALFSHAFT SEAL BUILT ON OR BEFORE 10/14/2013 ISSUE Some 2009-2014 Escape, 2009-2011 Mariner, 2010-2014 Fusion, 2010-2011 Milan, 2012-2014 Edge/Explorer, and 2013-2014 Taurus/MKT/MKZ vehicles built on or before 10/14/2013 and equipped with a 6F35 automatic transmission may exhibit a fluid leak from the left hand (LH) transmission halfshaft seal due to wear on the transmission case bushing.
NHTSA’s Office of Defects Investigation opens these when complaints point to a possible safety defect. Many end in a recall.
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-spe
On May 27, 2014, amended June 2, 2014, Ford Motor Company (Ford) submitted a Defect Information Report (DIR) to NHTSA describing a safety defect that may result in a sudden loss of power steering assist while driving in approximately 746,067 model year (MY) 2008 through 2011 Ford Escape vehicles equipped with electric power assisted steering (NHTSA 14V-284, Ford 14S05). Ford's DIR described the defect condition as a poor signal to noise ratio [SNR] in the torque sensor within the Electric Power
On February 21, 2013, the Office of Defects Investigations (ODI) opened Preliminary Evaluation PE13-003 to investigate allegations of electronic throttle body (ETB) failures resulting in sudden reduction of engine power in model year (MY) 2009-2013 Ford Escape, Fusion, Mariner and Milan vehicles. During this investigation, Ford identified a condition in subject vehicles equipped with 2.5L and 3.0L engines that may result in a sudden reduction of engine power.According to Ford, the ETB internal m
In its response to the agency, Ford acknowledged a higher than normal level of glass breakage incidents in the model year (MY) 2010 to early-build MY 2011 subject vehicles.The incidentsoccurred when the liftgate glass was being opened, or more typically while being closed, but in both cases while the vehicle was stationery, i.e., not moving on the roadway.Additionally failures often occurred during early morning hours when ambient and/or liftgate glass temperatures may have been lower.Ford advis
Source: NHTSA Office of Defects Investigation public data (complaints, manufacturer communications, investigations), model years 2010 and later. Had a safety problem? Report it to NHTSA.
In complaints filed with NHTSA for model years 2010–2013, owners most often name: power train, vehicle speed control, steering. 367 complaints are on record.
No. A complaint is an unverified report from an owner. A technical service bulletin (TSB) is the manufacturer telling dealers how to fix a known issue; it is not a safety recall and is usually covered only under warranty. A recall is a formal safety action, and its repair is free.
File a vehicle safety complaint at NHTSA.gov. NHTSA reads every report, and patterns of complaints are what open defect investigations and, eventually, recalls.
