Defect investigations
Daimler Trucks North America Recalls
On April 23, 2018, the National Highway Traffic Safety Administration (“the federal safety agency”) opened Audit Query (AQ18002) to assess the timeliness and scope of four recalls filed by Daimler Trucks North America, LLC (“DTNA”). the federal safety agency 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. the federal safety agency and DTNA entered into a Consent Order on December 29, 2020, to resolve the federal safety agency’s assertions that certain recalls within the scope of AQ18002 were untimely, DTNA failed to timely submit certain manufacturer communications to the federal safety agency, and DTNA failed to submit field reports to the federal safety agency 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. the federal safety agency and DTNA agreed to a two-year term for the Consent Order—with an option for the federal safety agency 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 the federal safety agency to discuss potential safety issues, recent manufacturer communications, and recall decision-making, among other things; quarterly meetings with the federal safety agency 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 the federal safety agency; 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 the federal safety agency. On December 22, 2022, the federal safety agency extended the Consent Order for a term of one year due to concerns about DTNA’s compliance with its recall-related obligations. Specifically, the federal safety agency 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 the federal safety agency during the term of the Consent Order. the federal safety agency 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 the federal safety agency as to DTNA’s performance under the Consent Order.

What 2007 Western Star 4900EX owners say
Most recent owner complaints, unedited.
On march 12, 2009 I bought 8 sumitomo 255/70r22.5 model #st727 tires for my commercial truck. Aprox. 50k miles of use one of the tires are cracking from the top of the tire going down the side wall. I was told by the retailer that the tire did not show any signs of impact and that it is only a stress crack and not a defect.
