Western Star 5700: recalls, complaints and investigations.
Evidence summary
- Evidence found
- 0 recent recall campaigns, 0 complaint rows, and 2 monitored investigations.
- Source coverage
- NHTSA complaint and current-action window 2024-08-24 to 2026-08-24; historical campaign count uses the complete official pre- and post-2010 recall files acquired for this release.
- What this means
- The records were matched to the NHTSA make/model identity “Western Star 5700”. Each evidence type is reported separately.
- What this does not mean
- Complaint reports are allegations, not defect findings or a safety score. Counts are not normalised for sales, registrations, mileage or exposure, and a zero does not prove safety.
Official recall campaigns
Campaigns received in the monitoring window
Zero NHTSA recall campaigns for this model family were received in the monitoring window. The historical count above may still include earlier campaigns.
Consumer reports — allegations
Complaint aggregates by model year
Zero complaint rows matched this make/model in the monitoring window. That is not a safety clearance.
NHTSA says complaints are consumer reports. RecallCheck excludes narratives, VINs, names, contact details and locations. A crash, fire, injury or death flag is reported information, not an independently verified causal finding.

DP26002: Redundant wheel fastener locking mechanism closed
The Office of Defects Investigation (ODI) received a petition on November 21, 2025, requesting a defect investigation to “determine whether the absence of a redundant mechanical wheel-fastener locking mechanism constitutes a safety-related defect in motor vehicles and motor-vehicle equipment” in the heavy-vehicle sector. On March 4, 2026, NHTSA opened Defect Petition DP26002 to evaluate the petitioner's request. The petition itself can be reviewed at NHTSA.gov under ODI number 11703245. The petitioner focused on all vehicles utilizing the 10-285.75 mm bolt wheels, also known as 10 Hole 22.5" Hub Pilot Wheels, as the subject of the petition. ODI conducted a comprehensive search of Vehicle Owner Questionnaire's (VOQ) and Early Warning Reporting (EWR) data for vehicles equipped with the subject wheels. Furthermore, ODI reviewed six months of the Federal Motor Carrier Safety Administration's Motor Carrier Management Information System violation data for commercial vehicles cited for loose/missing wheel fasteners. After a review of this data, ODI has found insufficient evidence to support the petitioner's claim that a safety-related defect exists. The data indicates that instances of loose or missing fasteners typically occur at higher mileages following fleet maintenance activities, rather than as a result of an inherent vehicle manufacturing or design defect. Furthermore, commercial motor vehicle operators are required to conduct daily pre-trip inspections to detect and mitigate loose fasteners before operation. In the absence of a Federal Motor Vehicle Safety Standard requiring wheels to have a redundant locking system and given the lack of evidence establishing a systemic safety defect, ODI is denying this Defect Petition. The denial of this petition does not foreclose the agency from taking further action if warranted or making a future finding that a safety-related defect exists based upon additional information the agency may receive.

EA25006: Automatic Emergency Braking Errors open
On May 26, 2023, the Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE23010) to assess reports of false positive activation of the Automatic Emergency Braking (AEB) system in model year (MY) 2017-2022 Daimler Trucks North America (DTNA) vehicles. The reports alleged that activation of the AEB system occurred while driving with no apparent obstruction in the vehicle's forward path, resulting in sudden vehicle deceleration. DTNA indicated that it received of a total of 315 reports that may relate to the alleged defect in MY 2017-2022 DTNA vehicles. DTNA stated that the vast majority of false positive activation of the subject systems occur in very limited durations and result in a five mile per hour deceleration. ODI considered four AEB systems offered by DTNA: Detroit Assurance 2.0, Detroit Assurance 4.0, Detroit Assurance 5.0, and Wabco OnGuard. ODI’s analysis shows that of the Detroit Assurance versions, all are failing at similar rates. The OnGuard AEB systems equipped on the same model and model year vehicles have experienced a significantly lower claim rate. To date, ODI has received a total of 32 consumer complaints of inadvertent activation of AEB in MY 2017-2022 DTNA vehicles. In total, ODI reviewed 347 unique (i.e., non-duplicative Vehicle Identification Numbers) reports that may relate to the alleged defect, which include 24 reports involving a crash, 13 reports involving an alleged injury and one report with a fatality. PE23010 has been upgraded to an Engineering Analysis to further assess the scope, frequency, and potential safety related consequences of the inadvertent AEB activations in MY 2017-2022 DTNA vehicles.
