What NHTSA says
Source: Office of Defects Investigation, as filedIn a letter received on October 24, 2018, a citizen petitioned the National Highway Traffic Safety Administration (NHTSA) to initiate a safety defect investigation into frame weld deficiencies on model year (MY) 2018 'JL' Jeep Wrangler vehicles. The petitioner described a broad list of frame weld deficiencies, including porous welds, excessive slag, lack of weld penetration, over penetration of welds, overweld or weld drip, and weld splash. The weld defects are allegedly located at a variety of locations on the frame assembly. On November 16, 2018, the Office of Defects Investigation (ODI) opened a Defect Petition (DP18-004) to evaluate whether to grant or deny the petition. On March 8, 2019, ODI sent an Information Request letter to Fiat Chrysler Automobiles (FCA) requesting information on frame weld related issues on all MY 2018-2019 Jeep Wrangler 'JL' vehicles. Due to a previous steering related recall that was caused by a misaligned weld on the front track bar (NHTSA Recall No. 18V-675), ODI opted to include a request for additional information concerning reports of steering shimmy or wobble, loose steering, and steering lockup in the March request letter. ODI has performed a preliminary analysis on the information obtained from FCA. Based on ODI's review of the applicable materials, NHTSA has decided to grant the petition. While reviewing the applicable materials obtained from the manufacturer, ODI identified various reports and references to frame welded component detachments that were outside of the scope of NHTSA Recall No. 18V-675. Additionally, the information that FCA provided did not adequately address whether frame weld quality deficiencies compromise the structural integrity of vehicles, and therefore may pose an unreasonable risk to motor vehicle safety. Finally, ODI needs to further evaluate the alleged steering-related defects reported through MY 2019 and the alleged defects' relation to weld quality. The petition was granted on September 16, 2019. Preliminary Evaluation PE19-012 has been opened to further assess the scope, frequency, and potential safety-related consequences of alleged weld quality deficiencies and steering related concerns on the MY 2018-2019 'JL' Jeep Wrangler vehicles.

A Defect Petition is a petition from a member of the public asking NHTSA to open a defect investigation; the agency grants or denies it and publishes the reasons. 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 DP18004 a recall?
No. A defect petition 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 DP18004 still open?
No. It closed on Sep 17, 2019 without a recall.
Which vehicles does DP18004 cover?
NHTSA opened it on 2 model years: 2019 Jeep Wrangler, 2018 Jeep Wrangler. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
