Summary

On April 3, 2017, the Office of Defects investigation (ODI) opened Engineering Analysis (EA17-001) as an upgrade to a Preliminary Analysis (PE16-005). The investigation focused on alleged windshield wiper failures on 2015-2016 MY Freightliner Cascadia trucks. ODI received Early Warning Reporting (EWR) field reports from the manufacturer describing wipers that intermittently failed to operate, causing a loss of visibility for the driver while driving in rain or snow. Several of the reports alleged multiple vehicles experiencing the failure, while multiple failures also happened on the same vehicle. Many of the field reports indicated the windshield wiper problem was resolved once the wiper motor was replaced.Following a detailed analysis of data collected by ODI it was determined that a low failure rate for a complete loss of wiper function existed on the subject vehicles. Given this low failure rate and the Technical Service Bulletins (TSBs) to address this issue released by DTNA, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists. The agency reserves the right to take further action if warranted by the circumstances.For a detailed summary of the investigation see attached closing resume document.The ODI reports cited above can be reviewed at: http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID using the following complaint identification number: 11141519

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.
