Recalls, owner-reported complaints, investigations and safety data

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.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

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.

Powertrain (other)
Filed May 14, 2026

After a decel to 20ish mph, the automated manual transmission attempted to shift into gear to begin acceleration. The transmission made load noises indicating a failure followed by a transmission warning with the fault code being 617 FMI 14. All acceleration and engine braking ability was disabled, increasing the risk of an accident due to the vehicle being disabled. A similar safety recall for the same vehicle would be NHTSA #24V-190 which causes the vehicle to become disabled and increase a crash risk. This is a known issue caused by compressed air contamination according to Eaton Transmissions service bulletin TAIB-1006, which was first published April 2023. In the over 3 years since the service bulletin was released, Eaton, Peterbilt, Paccar, and Cummins(engine manufacturers) have failed to develop adjusted maintenance intervals, added inspections, or additional filtration to prevent contamination of the transmissions air system. They've instead passed the financial burden of repair on the customers by denying warranties. The dealer determined based on TAIB-1006 that the MTM requires replacement and the air system cleaned of contamination. This was based on data and not a detailed inspection to determine the internal failure.

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. Older model years have had longer for reports to accumulate.
