Data Attribution & Reporting Methodology: Complaints are unverified voluntary submissions to the NHTSA Office of Defects Investigation (ODI). Because multiple vehicle components can be cited within a single owner complaint submission, component-level rollups may sum to more than the unique complaint count (667). Injury and fatality entries in the detailed table reflect raw values entered by reporting consumers across individual submissions; they are not deduplicated casualty statistics and may include duplicate or unverified entries. Complaint volume is not normalized for sales volume or vehicle mileage and does not represent an audited component failure rate.

Official NHTSA Defect Investigations (1)

1 OPEN

Formal safety defect inquiries and engineering analyses opened by the NHTSA Office of Defects Investigation (ODI)

Official Federal Inquiries: NHTSA opens a defect investigation when safety screening or consumer defect trends indicate a potential unreasonable safety risk. An open investigation is a formal inquiry and does not by itself confirm a defect or result in a mandatory recall.
OPEN Engineering Analysis (EA) ODI Action #EA23001
Opened: 2023-03-17 • Currently Active

High pressure fuel pump failure

Affected Component: FUEL SYSTEM, DIESEL:DELIVERY:FUEL PUMP

The Office of Defects Investigation (ODI) opened PE21-021 on October 14, 2021, to investigate incidents alleging a stall/loss of motive power as a result of high-pressure fuel pump failures in certain model year (MY) 2019-2020 Ram 2500, 3500, 4500, and 5500 heavy duty trucks equipped with 6.7L Cummins turbodiesel engines. During the investigation, ODI sought to determine if the related defect allegation was limited in scope to the recalled popula...
