Freightliner preliminary evaluation PE24032
EVDM connector plate separation. NHTSA’s Office of Defects Investigation opened this preliminary evaluation about the electrical system on 9 model years (2020–2025). Opened Nov 5, 2024, closed Jun 10, 2025 after 7 months. It led to safety recall 25V046000. became a recall
What NHTSA says
Source: Office of Defects Investigation, as filedThe Office of Defects Investigation (ODI) opened this Preliminary Evaluation (PE) on November 6, 2024, to investigate Electric Vehicle Distribution Module (EVDM) connector plate separation on model year (MY) 2020-2025 Freightliner eCascadia and MY2022-2025 Freightliner eM2 electric trucks. The EVDM connector plate contains multiple safety-related circuits including Anti-lock Brake System (ABS), stability control and vehicle protective mechanisms to de-energize the high-voltage propulsion system. In January 2025, prior to Daimler Truck North America's (DTNA) final response to ODI's Information Request (IR) letter, DTNA conducted controlled testing of the EVDM. The final test results demonstrated that in certain circumstances of EVDM separation, the vehicle may lose motive power without prior warning to the driver. Based on the EVDM testing results, DTNA filed a recall (NHTSA ID 25V-046). This recall covers MY2020-2025 Freightliner eCascadia and MY2022-2026 Freightliner eM2 electric trucks. These vehicles will have the EVDM replaced if the plate shows separation from the housing. The recall chronology identified that DTNA had received nine warranty claims and six field reports for this issue. This Preliminary Evaluation has been closed as a result of the manufacturer filing recall 25V-046. The Agency reserves the right to take additional action if warranted by future 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 resumes carrying the full reasoning are linked below.

These are NHTSA’s own files, served from the agency’s site — the resumes are what ODI wrote when it opened and closed the action, and the rest is the correspondence behind them, including what the manufacturer sent when the agency asked. They are linked, not copied: where a document names the people who wrote in, that redaction is the agency’s to make and its copy is the one you should read.
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 PE24032 a recall?
No — it is the investigation that led to one. Recall 25V046000 is the campaign; its page carries the remedy.
Is PE24032 still open?
No. It closed on Jun 10, 2025 and led to recall 25V046000.
Which vehicles does PE24032 cover?
NHTSA opened it on 9 model years: 2020 Freightliner E-Cascadia, 2021 Freightliner E-Cascadia, 2022 Freightliner E-Cascadia, 2023 Freightliner E-Cascadia, 2024 Freightliner E-Cascadia, 2025 Freightliner E-Cascadia and more. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
