Cummins Recalls, Complaints & Safety Data

NHTSA safety recalls, owner-reported complaints and investigations, by model and model year · 1988–2003

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received. This total counts a complaint once for each Cummins model year it names.
7
Safety recallsDistinct NHTSA recall campaigns covering at least one Cummins model year. One campaign can cover several models and many model years; it is counted once here.
5
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Complaint totals count a report once for each model year it names; recall totals count a campaign once per model.
