Recall campaignsA 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.

Open 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.

What a recall is

Safety recall
A 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.
Safety investigation
NHTSA 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.
Manufacturer communication
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.

Safety investigations

NHTSA inquiries naming this vehicle. An investigation is not a finding of a defect, and it is not a recall.

Automatic Emergency Braking Errors

Opened Oct 23, 2025

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. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

AQ18002ClosedAudit Query

Daimler Trucks North America Recalls

Opened Apr 23, 2018
Closed Jul 11, 2024

On April 23, 2018, the National Highway Traffic Safety Administration (“NHTSA”) opened Audit Query (AQ18002) to assess the timeliness and scope of four recalls filed by Daimler Trucks North America, LLC (“DTNA”). NHTSA subsequently expanded AQ18002 to examine the timeliness and scope of three additional DTNA recalls and compliance with early warning reporting and manufacturer communications reporting requirements. NHTSA and DTNA entered into a Consent Order on December 29, 2020, to resolve NHTSA’s assertions that certain recalls within the scope of AQ18002 were untimely, DTNA failed to timely submit certain manufacturer communications to NHTSA, and DTNA failed to submit field reports to NHTSA as required. As part of the Consent Order, DTNA agreed to a total civil penalty of thirty million dollars ($30,000,000), of which ten million dollars ($10,000,000) was paid on January 12, 2021. Also, of that total civil penalty, DTNA agreed to spend five million dollars ($5,000,000) on the specific performance obligations to develop advanced data analytics capabilities to enhance its ability to detect and study emerging safety-related defect trends on its vehicles (“Safety Data Analytics infrastructure”) and an advanced data analytics and reporting platform that integrates data on emerging safety-related defect trends on its vehicles and recall lessons learned (“Safety Communications Platform”). The Consent Order also held fifteen million dollars ($15,000,000) of the civil penalty in abeyance pending DTNA’s satisfactory completion of the requirements of the Consent Order, and its compliance with the Safety Act, and regulations thereunder. NHTSA and DTNA agreed to a two-year term for the Consent Order—with an option for NHTSA to extend the Consent Order for an additional year, if warranted. In the Consent Order, DTNA agreed to numerous performance obligations, including monthly meetings with NHTSA to discuss potential safety issues, recent manufacturer communications, and recall decision-making, among other things; quarterly meetings with NHTSA to discuss DTNA’s progress on the performance obligations under the Consent Order, including the Safety Data Analytics infrastructure and Safety Communications Platform, and any issues related to compliance with the Consent Order, Safety Act, or regulations; development of written procedures and employee training materials to help DTNA comply with its legal obligations to timely identify and report safety defects and noncompliances, submit complete and accurate recall filings, and timely submit manufacturer communications and field reports to NHTSA; and identifying and reporting previously unreported manufacturer communications and field reports. Also, via the Consent Order, DTNA acknowledged that the failure or inability to identify a specific root cause, develop an adequate remedy or repair, or confirm the affected population of vehicles are not bases for delaying filing a recall with NHTSA. On December 22, 2022, NHTSA extended the Consent Order for a term of one year due to concerns about DTNA’s compliance with its recall-related obligations. Specifically, NHTSA expressed concerns about the completeness of DTNA’s recall reports and issues identified with owner notification letters during the term of the Consent Order, as well as the length of time that DTNA took to consider a straightforward noncompliance issue before filing a recall and DTNA’s interactions with NHTSA during the term of the Consent Order. NHTSA addressed these concerns with DTNA during the third year of the Consent Order. The extended term of the Consent Order expired on December 28, 2023. Based on the Consent Order, this investigation, AQ18002, is closed. Closure of this AQ has no bearing on the terms of the Consent Order or DTNA’s ongoing legal obligations, and it does not represent a determination by NHTSA as to DTNA’s performance under the Consent Order.
