Summary

A january 2008 service bulletin suggests that certain model buses should upgrade to a high torque wiper motor.the tsb also alluded to wiper motor failures. Therefore, odi opened this investigation to determine the failure mode, frequency and safety significance since the wiper system is considered to be a critical item of safety equipment and is required by a federal standard. Van hool re-evaluated the issue and decided to conduct a safety recall. Van hool determined that there was an issue, but it was an issue with improperly finished linkage components that were causing the wiper motor to fail. All wiper motor linkages on the affected buses will be replaced under the recall. The recall action resolves the issues raised by this investigation. Accordingly, this investigation is closed.

An NHTSA investigation looks into whether a safety defect exists. Opening one is not a finding. Outcomes can include a recall, closure without action, or further inquiry.
