Roof Skin Separation While Driving. NHTSA’s Office of Defects Investigation opened this preliminary evaluation about the roof and pillars on 2 model years (2004–2005). Opened Feb 1, 2019, closed Dec 12, 2019 after 10 months without a recall. closed
What NHTSA says
Source: Office of Defects Investigation, as filedOn August 23rd, 2018 - the Office of Defects Investigation (ODI) received a media inquiry pertaining to a motorist experiencing separation of the roof skin from their Cadillac XLR while driving. Based on the data in-hand at that time and a subsequent (December) consumer complaint, ODI opened PE19-001 on February 1, 2019 to evaluate the scope of this condition in the 2004 - 2005 XLR population. The subject vehicle model is a two-seat roadster equipped with an electrically powered retractable roof system. The outer roof skin is a Sheet Molded Composite (SMC) which is adhered to the magnesium alloy roof frame. ODI's February 7, 2019 Information Request (IR) letter to General Motors (GM) covered the entirety of XLR production: MY 2004 - 2009. GM's March 21, 2019 IR response attributed the separations to an unexpected oxide layer on the magnesium framework. A total of eight separations were identified, six of which coincided with consumer complaints to NHTSA. Separations occurred at two per calendar year with the most recent taking place in late 2018. An additional twenty-one noise, fit/finish/ functionality claims were identified that did not lead to separations. ODI compared the separation rate in the subject vehicles to those in to two roof skin separation safety recalls involving the Corvette (06V181: 2005 - 2006 Corvette; 09V491: 2005 - 2007 Corvette) to find that the subject vehicles took over ten years of exposure to reach the failure rate that triggered the 06V181. Since PE19-001 opened, ODI has received only one additional consumer complaint which reported wind noise symptoms. The complainant has not responded to outreach efforts by ODI or GM. Based on a low failure rate, sporadic occurrence, and high detectability of the alleged defect in the subject vehicles, this investigation is closed. Further use of agency resources on this matter is not warranted. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist in the subject vehicles. The agency reserves the right to take further action if warranted by the circumstances. The ODI complaints cited above can be viewed at www.nhtsa.gov under the following ODI identification numbers: Separations: 11155574, 11101657, 11012176, 11012166, 10970736, 10970383, 10653304Note: ODI 11012176 & 11012166 pertain to the same incidentNot Separated: 11243947, 11194359, 11176647, 11173362, 11074433, 10985013 Note: 11176647 & 10985013 pertain to the same incident
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 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 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 InvestigationIs PE19001 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 PE19001 still open?
No. It closed on Dec 12, 2019 without a recall.
Which vehicles does PE19001 cover?
NHTSA opened it on 2 model years: 2004 Cadillac XLR, 2005 Cadillac XLR. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
