NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Equipment Query EQ15-006.
try.vin does not copy NHTSA's investigation documents; NHTSA's investigation record lists the ones NHTSA has published.
In a part 573 Safety Recall Report dated March 4, 2015, Haldex Commercial Vehicle Systems notified NHTSA that it decided that a defect exists in certain Type 30/30 Long Stroke Haldex Life Seal Actuators manufactured from December 17, 2013 to February 18, 2015. The affected actuators are equipped with an incomplete attachment of the internal rubber diaphragm to the actuation mechanism of the parking brake section of the Life Seal Actuator. If the brakes drag or overheat it may result in smoke or thermal damage to the vehicle and/or chassis components.
On December 7, 2015 the Office of defects Investigation opened Equipment Query, EQ15-006, in order to obtain Haldex's customer list and to contact the companies that purchased the defective actuators, notify them of the defect, and ensure thorough safety recalls are conducted where appropriate. Eighteen Information Request letters were sent out on May 3, 2016, to each corresponding company requesting a safety recall decision be made, the requisite notice filed, and recall campaign conducted where appropriate. As a result, the following five companies have filed defect reports and are conducting safety recalls:?Meritor, Inc. (16E-004) ?John Evans Mfg. (16V-470) ?West-Mark (16V-399) ?Vanguard National Trailer Company (16V-025) ?Western Trailer Company (16V-019)The following six companies have provided written statements that they were not manufacturers, did not receive, and/or did not sell any products containing the defective actuators to costumers in the USA:?Schnure Manufacturing Company, Inc.?Bud's Spring & Suspension Service ?Aurora Parts & Accessories ?Westmor Industries, LLC ?Stoughton Trailers, LLC ?Mac TrailerThe following six companies were included in recalls prior to the opening of the EQ:?Holland Binkely Company (15V-017) ?New Life Transport Parts (15V-017) ?Westport Trailers (15V-026) ?Hendrickson (15V-017) ?Fenix Forwarding Inc.

They will be referred to Chief Counsel: ?Pratt Industries All vehicle and motor vehicle equipment manufacturers have been identified and have either filed recall reports and are conducting recalls, or have provided responses explaining why they are not conducting recalls. Accordingly, this equipment query investigation is closed.

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.
