Ford and Mercury preliminary evaluation PE11016

Rear Liftgate Window Glass Breakage. NHTSA’s Office of Defects Investigation opened this preliminary evaluation about the hatchback/liftgate on 4 model years (2010–2011). Opened Apr 27, 2011, closed Aug 18, 2011 after 4 months without a recall. closed

What NHTSA says

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 advised that it investigated the failures but failed to identify an anomaly in the glass manufacturing process (which is often a factor in glass breakage trends ODI investigates) that could explain the reports. It did however identify a potential thermal expansion/compression condition in the mounting of the rear wiper motor to the liftgate glass. Starting at MY 2008 vehicle production the motor was attached to the glass using an adhesive. Ford revised that design to a nut and bolt type attachment in October 2010, during MY 2011 vehicle production. ODI's review of Ford data indicates that vehicles built after this change exhibit lower glass breakage rates. Among the 296 consumer complaints on the subject vehicles, ODI identified 15 injury incidents resulting in a total of 18 alleged injuries. All the injuries were minor in nature and consisted mainly of superficial skin cuts or minor lacerations, with two of the injury incidents occurring when vehicle owners were cleaning up broken glass. Additionally both the injury rate and report rate (including warranty claims) are low in comparison to similar investigations resulting in safety recalls (see PE04-045, MY 2002 Ford explorer liftgate glass failure, which resulted in NHTSA safety recall 04V442). In November 2010 Ford issued Technical Service Bulletin (TSB) 10-22-10 to address reports of liftgate glass breakage on all MY 2010 vehicles, and MY 2011 vehicles built through 10/15/2010, the date the above design revision was implemented. The TSB enables owners of affected vehicles to have a broken liftgate glass replaced under normal vehicle warranty, which would not otherwise be a warrantable failure, with the revised design liftgate glass. A safety-related defect has not been identified at this time and further use of agency resources does not appear to be warranted. Accordingly, this investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The agency will monitor this issue and reserves the right to take further action if warranted by the circumstances.

A Preliminary Evaluation is the first formal stage: NHTSA has decided the complaints and other information it screened are worth a closer look, and asks the manufacturer for its own data on the condition. The summary is the agency’s own text from its investigation file, unedited; the opening and closing resumes with the full reasoning are on NHTSA’s site under this number.

What this means for an owner

Source: and what happens next

An investigation is not a finding that a defect exists, and it puts no duty on anyone. NHTSA opens a Preliminary Evaluation when complaints and other reports suggest a condition worth asking the manufacturer about; it upgrades to an Engineering Analysis when the answers warrant testing; it closes either when it recommends a recall, when the manufacturer recalls on its own, or when no defect trend is found. The agency’s own goals are about four months for a petition, eight for a Preliminary Evaluation or a Recall Query and eighteen for an Engineering Analysis; many run longer.

This one closed without a recall. That means NHTSA found no defect trend it chose to act on at the time, or the manufacturer addressed the condition another way (a service campaign or a bulletin, which have their own pages). A closed file can be reopened if new reports arrive.

Common questions

Source: NHTSA Office of Defects Investigation

Is PE11016 a recall?

No. A preliminary evaluation is NHTSA asking questions, not a recall. A safety recall carries an NHTSA campaign number and a duty to repair for free; this one closed without one. Whether one particular vehicle has an open recall is a VIN question at nhtsa.gov/recalls.

Is PE11016 still open?

No. It closed on Aug 18, 2011 without a recall.

Which vehicles does PE11016 cover?

NHTSA opened it on 4 model years: 2010 Ford Escape, 2011 Ford Escape, 2010 Mercury Mariner, 2011 Mercury Mariner. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
