NHTSA's summary

As NHTSA's Office of Defects Investigation wrote it for Engineering Analysis EA17-001.

try.vin does not copy NHTSA's investigation documents; NHTSA's investigation record lists the ones NHTSA has published.

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.

What an NHTSA investigation is

NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.

An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
