On August 31, 2020, the Office of Defects Investigation (ODI) opened a recall query, RQ20001, to investigate the allegations of water intrusion into the truck cab signal-detect and activation module (SAM cab).The investigation further evaluated the effectiveness of the original recall remedy, and the installation of an updated drip shield as it relates to continual water intrusion resulting in the loss of electrical functions and potential fire.The potential hazard was the increased risk of a crash and injury in certain model year (MY) 2007-2021 Freightliner Cascadia P3 vehicles manufactured by Daimler Trucks North America (DTNA). ODI sent DTNA an information request (IR) letter on September 29, 2020.DTNA's November 20, 2020, IR response detailed how the company had implemented various improvements through recall 09V024 and multiple technical service bulletins (TSBs) to mitigate water intrusion.The effectiveness of new windshield seals and revisions to the drip shield is evident by the downward trend in claims rate from an average high of 7.64% in the beginning product life of Cascadia P3 (MYs 2007-2009), to 1.79% average for MYs 2011-2018, and down to 0.49% towards the end of the Cascadia P3 production.Moreover, the data shows that most failures occurred within the first three years of service with a significant downward trend thereafter. In view of the current overall low failure rate, the nature of early-life failure, and failure rate trending downward since model year 2017, this Recall Query (RQ) is closed. The Agency reserves the right to take additional action if warranted by future circumstances.

RQ20001

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.

AQ18002

On April 23, 2018, the Office of Defects Investigation (ODI) opened this Preliminary Evaluation (PE18-004) to investigate certain alleged defects affecting the Powernet Distribution Box (PNDB) and associated wiring on certain model year (MY) 2011-2016 Freightliner Cascadia (P3 platform) truck tractors that may result in disruption or loss of electrical power to the PNDB itself and other electrical circuits, thermal events, and/or vehicle fires.On May 7, 2018, ODI sent an Information Request (IR) letter to Daimler Trucks North America LLC (DTNA). On June 19, 2018, ODI received an IR response from DTNA that included vehicle production, consumer complaint, field report, warranty, manufacturer actions, changes and other data related to the alleged defects. On April 8, 2019, ODI received a supplemental IR response from DTNA that included their assessment of the alleged defects. Furthermore, ODI engaged in discussions with the manufacturer about the alleged defects on multiple occasions during the course of this investigation. ODI analysis of all available data indicates there is not an apparent defect trend. The most recent field report data reviewed was from 2017Q1 and the most recent complaint data was received by ODI in 2019Q1. The complaint rate is low. Most warranty claims occurred early in the vehicles' service life, and with the newest of the subject vehicles being over four years old, they are all now beyond that point. The warranty claim rates for loose input or output terminals (0.16%), loose fuses (0.25%), PNDB power (B+) supply cable corrosion or improper PNDB power (B+) supply cable routing and/ or securement (0.00%) are all low.The most serious consequence in the warranty claim data alleged engine shutoff with a vehicle in motion. While some vehicles did experience a loss of electrical power resulting in loss of motive power with no immediate restart capability, the bulk of the warranty claims were for vehicles equipped with an optional cab power disconnect switch solenoid with an automatic reset feature that may exhibit a brief, intermittent loss of power. If the input and output voltages differ by an unacceptable amount, potentially due to foreign object debris or corrosion on the solenoid's contacts, the PNDB senses the difference and enters an auto-reset mode in an attempt to correct the condition. The internal contacts open for one second, stopping the flow of electricity, and then close, restoring the flow for two seconds. This cycle is repeated for up to five times; after a maximum of thirteen seconds, the PNDB defaults to the on position and electrical power is restored. This condition exhibits a transient loss of power but it does not cause any permanent engine disablement. As a precaution, the solenoid-equipped PNDB part was modified in August 2017 to eliminate the auto-reset feature. Since 2010, there has been only 1 report of vehicle fire and zero reports of crash, injury or death. Accordingly, this investigation is closed. The closing of this investigation does not constitute a finding by the federal safety agency that no safety-related defect exists. The agency reserves the right to take further action if warranted by the circumstances.

PE18004

The Office of Defects Investigation (ODI) received Early Warning Reporting (EWR) data from the manufacturer that indicated some number of subject vehicles had allegedly experienced a fracture of one or more support brackets resulting in an unsecured air brake reservoir.This could result in a loss of air pressure necessary for proper service brake application and a potential road hazard if the reservoir separates from the vehicle in operation.By letter dated August 15, 2012, Daimler Trucks North America LLC (DTNA) has notified ODI that it has initiated a safety recall (identified by NTHSA Recall No. 12V‑405 and DTNA Recall No. FL-631) to address a safety defect in approximately 1,663 model year (MY) 2009 through 2012 Freightliner 114SD, Business Class M2, Cascadia, Coronado, Sterling 9500 and Western Star 4700 trucks manufactured from July 7, 2008 through December 15, 2011, originally equipped with a specific perpendicular oriented air brake reservoir support bracket (P/N 12-22981-000).To date ODI is unaware of any bracket failures that resulted in a complete separation of the reservoir from the vehicle.Affected owners will be notified by DTNA beginning October 15, 2012 and affected vehicles will have the subject air brake reservoir support brackets replaced with a more robust bracket.Repairs will be performed by DTNA authorized service facilities.Copies of DTNA's reimbursement plan for pre-notification remedies will be submitted to ODI as a supplemental report when available.Accordingly, this investigation is closed.

PE12018

DTNA submitted a 573 Recall notice (11V‑289) prior to the IR response date and therefore was granted permission to forgo submission of the IR response.Freightliner reported that Fontaine's TSB issued in March had resulted in the remedy of 55 percent of all subject vehicles with an additional 33% scheduled by the time of their 573 submission.Freightliner will issue another notification 1 July if 100% of the subject population is not remedied by that time.ODI is aware that the Ultra LT 5th wheel was also installed on several other OEM's vehicles.ODI will work with Fontaine and the manufacturers to ensure that the remaining vehicles are identified and remedied.
