Takata recall mhc kenworth has replaced or corrected the drivers low beam light 5 times, 3 for fee and 2 as a cost to my business. The this headlight continues to malfunction and the light bulb IS not even blown. The dashboard lights goes pitch black dark. The orange engine outline comes on every single time the malfunction occurs. This IS not safe and we cannot continue driving this truck like this. The truck continues to misfire after the warranty covered the injectors replacement. Some times the entire electrical shut down in the truck. I need answers asap as this can cost thousands in fines and dot fees! This has occurred more than once, numerous times with the most recent being dec 2018 and jan 2019. The cabinet handles fell off and the both arm rests on the driver's side. This 3 year old truck IS falling apart.

Defect investigations

- Haldex Brake Chamber Failures
The Office of Defects Investigation (ODI) opened this Preliminary Evaluation (PE21018) based on eleven Vehicle Owner Questionnaires (VOQ).

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