NHTSA Defect Investigations for the 2000 Mercedes-Benz CLK430

The Office of Defects Investigations (ODI) is an office within the NHTSA which investigates serious safety problems in the design, construction or performance of vehicles. The NHTSA is authorized to order manufacturers to recall and repair vehicles, if the ODI finds a safety issue. NHTSA investigations for the 2000 Mercedes-Benz CLK430, both ongoing and closed, are listed below:

    Summary: The Office Of Defects Investigation (ODI) opened this preliminary evaluation to investigate allegations of engine crankshaft pulley harmonic balancer failure that could result in loss of power-steering assist.ODI has received a total of 546 non-duplicative reports that allege engine crankshaft pulley harmonic balancer failure on all Mercedes-Benz vehicles using the subject component.the subject component failures are progressive in nature and only a small percentage of the complaints and warrant claims involved a failure that had progressed far enough to effect power steering performance (6 of 55 ODI complaints reference increased steering effort).there have been no crashes or injuries related to the alleged defect.a safety-related defect has not been identified at this time and further use of Agency resources does not appear to be warranted.accordingly, this investigation is closed.the closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.the Agency will take further action if warranted by the circumstances.see summary report attached for further detail.


    NHTSA Defect Investigation #DP05007

    • Status:
    • Date Opened: November 07, 2005
    • Date Closed: March 27, 2006
    • Recall: No recall issued

    Component(s): Power Train:Automatic Transmission

    Summary: The petitioner alleges that coffee from a cup, placed in the cup holder, spilled onto the gear shifter and shut down the vehicle's entire electrical system. The concern raised by the petitioner was investigated (SQ01-010) and was closed after ODI concluded that the facts did not demonstrate a safety-related defect.ODI has subsequently received nine more complaints alleging fluid contamination of the transmission shifter since the investigation was closed, none of which report crashes or injuries.these nine complainants mainly expressed dissatisfaction with the design of the cup holder and the cost of replacing the contaminated electronic selector module.similarly, in petitioner's case she was able to operate the vehicle to a place where it could be safety stopped after the liquid spillage.the petitioner has not provided any evidence of a safety-related defect.in view of the foregoing and the need to allocate and prioritize NHTSA's limited resources to best accomplish the Agency's safety mission, the petition is denied.
