The DRLs are required to deactivate when the hazard warning lights are activated, however, the DRLs on these vehicles override the hazard flashing functionality after the brake pedal is pushed for more than two seconds. Normal hazard flashing functionality returns once the service brake is released. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 108, "Lamps, Reflective Devices, and Associated Equipment."

The risk

If the hazard warning lamps are overridden by the DRL, oncoming vehicles may fail to be warned, increasing the risk of a crash.

The affected trucks are built with a driveshaft that may not transmit power to the wheels due to weld failure from corrosion.

The risk

If the weld fails causing a loss of power to the rear wheels, the vehicle operator may be unable to move the vehicle, or may experience deceleration if the vehicle is in motion, increasing the risk of a vehicle crash.

The remedy

PACCAR will notify owners, and dealers will replace the defective driveshafts, free of charge. The recall began on July 15, 2015. Owners may contact Kenworth customer service at 1-425-828-5000, or Peterbilt customer service at 1-940-591-4000. PACCAR's number for this recall is 15KWJ and 515-H.

The Office of Defects Investigation (ODI) opened this Preliminary Evaluation (PE21018) based on eleven Vehicle Owner Questionnaires (VOQ). These VOQs included seven wheel-end fires on various Kenworth and Peterbilt trucks.Several of the VOQs were submitted by a maintenance facility stating that the fires were due to power spring fractures within brake chambers manufactured by Haldex Commercial Vehicle Systems (Haldex). According to the reports, the fractured spring punctured the brake chamber diaphragm, resulting in a partial loss of compressed air to the park brakes, causing the brakes to drag and overheat. ODI sent an information request letter to Haldex on August 3, 2021. On October 17, 2021, Haldex submitted a complete response. In this investigation, ODI analyzed thousands of warranty claims as well as fleet reports of brake chamber replacements. ODI gathered information from multiple vehicle manufacturers and reviewed legal testimony alleging defects and laboratory reports that raised concerns about spring failures initiated by corrosion. ODI found that spring failures were often detectable as soon as they occurred. In the subject incidents, after detecting the failures, some operators continued driving to a maintenance facility rather than stopping and waiting for a mobile technician to address the issue, increasing the risk of fire. While over twenty entities purchased the subject component from Haldex, the VOQs that ODI received involved only PACCAR vehicles. Haldex completed replacement campaigns for several fleets operating PACCAR vehicles, reducing the risk of further failures. Brake chambers have a limited service life. Industry guidance generally recommends replacement every two to four years depending on operating conditions, with some manufacturers and fleets recommending even shorter intervals. Vehicles operating in salt-belt states—where the majority of VOQs originated—require more frequent replacement than vehicles in less corrosive environments. Haldex’s standard warranty is four years and unlimited mileage. ODI determined that the average time in service for warranty claims was 4.9 years and 260,000 miles. Currently, all of the chambers subject to this investigation are between five and ten years old. Given the absence of recent failures and because the subject components are now older than their expected service life, ODI is closing this investigation. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency reserves the right to take additional action if warranted by future circumstances.
