Pontiac engineering analysis EA13005
Brake Light Switch/Sensor Malfunction. NHTSA’s Office of Defects Investigation opened this engineering analysis about the brake lights on 4 model years (2005–2008). Opened Jun 6, 2013, closed Jul 1, 2014 after 13 months. It led to safety recall 14V252000. became a recall
What NHTSA says
Source: Office of Defects Investigation, as filedOn May 14, 2014 General Motors (GM) announced a recall action (14V-252) involving model year (MY) 2004-12 Chevrolet Malibu, MY 2004-07 Malibu Maxx, MY 2005-10 Pontiac G6 and MY 2007-10 Saturn Aura vehicles. An increased resistance can develop in the Body Control Module connection systems and result in voltage fluctuations in the Brake Apply Sensor (BAS, or brake light switch) circuit that can cause the brake lamps to malfunction. As a result, and according to GM, the brake lamps may illuminate when pedal application is not being applied or may not illuminate when pedal force is applied. Additionally, the cruise control may not engage or if it is engaged it may require increased pedal travel to disengage. Pedal application may not be required to move the shift lever out of PARK or additional travel may be required to move the shift lever out of PARK. Traction control, electronic stability control (ESC) and panic brake assist features may also become disabled. These failure conditions may increase the risk of a crash. The Office of Defects Investigation (ODI) opened Engineering Analysis EA13-005 on June 6, 2013 to further investigate complaints alleging that the brake lights did not operate properly on MY 2005-08 Pontiac G6 vehicles. The BAS in these vehicles produces a single analog voltage output proportional to the brake pedal's position. The BAS signal is used by various systems to determine both pedal position and rate of displacement, so a failure or inaccuracy of the signal may affect multiple systems. ODI also received similar complaints on MY 2009 Pontiac G6, MY 2004-11 Chevrolet Malibu and MY 2007-09 Saturn Aura vehicles that use the same BAS. All of these above models were included in the subject vehicle population of ODI's Information Request (IR) letter to GM. Prior to the recall announcement date, ODI received 855 reports of brake light malfunction resulting in one or several of the failure conditions. Eight (8) of the reports alleged crashes, with 1 resulting in an injury. Of these crash allegations, 2 were roll-away incidents, in which the shift interlock was moved out of PARK without pedal application and the vehicle rolled into another object. Three (3) crashes involved rear-end hits, which were believed to be due to brake light reversal. ESC/Traction Control failures were the alleged cause of 2 incidents, which resulted in unresponsive brake application and in 1 case caused the vehicle to leave the roadway. One (1) crash allegation was not counted as the circumstances of the crash were not related to any of the failure modes. ODI notes that it is difficult to determine the actual cause of incidents where brake light reversal or ESC/Traction Control failures were the alleged cause. In response to ODI's IR, GM submitted 2,268 unique reports that related to brake lamp malfunction. Combined with the data submitted during Recall Query 13-001, a total of 4,664 unique complaints were submitted. Twelve (12) of the GM reports alleged a crash, with 2 reporting minor injuries and 4 alleging property damage. Of the 12 reports, 3 involved brake light reversal allegations, 4 involved roll-away incidents and 2 involved ESC/Traction Control malfunctions. ODI did not include three (3) reports that involved allegations inconsistent with the alleged defect. This investigation is closed on the basis of GM's announcement of safety recall 14V-252.

A Engineering Analysis is the deeper stage, usually upgraded from a Preliminary Evaluation: NHTSA tests, requests engineering documents and decides whether a safety defect exists. 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 nextAn 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 became a recall. The campaign page carries the manufacturer’s filed defect, risk and remedy, the build window and every model year covered; whether one specific vehicle is included is settled by VIN at nhtsa.gov/recalls.

Common questions
Source: NHTSA Office of Defects InvestigationIs EA13005 a recall?
No — it is the investigation that led to one. Recall 14V252000 is the campaign; its page carries the remedy.
Is EA13005 still open?
No. It closed on Jul 1, 2014 and led to recall 14V252000.
Which vehicles does EA13005 cover?
NHTSA opened it on 4 model years: 2005 Pontiac G6, 2006 Pontiac G6, 2007 Pontiac G6, 2008 Pontiac G6. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
